Automatic lighting controls demonstration  

SciTech Connect

The purpose of this work was to demonstrate, in a real building situation, the energy and peak demand reduction capabilities of an electronically ballasted lighting control system that can utilize all types of control strategies to efficiently manage lighting. The project has demonstrated that a state-of-the-art electronically ballasted dimmable lighting system can reduce energy and lighting demand by as least 50% using various combinations of control strategies. By reducing light levels over circulation areas (tuning) and reducing after hours light levels to accommodate the less stringent lighting demands of the cleaning crew (scheduling), lighting energy consumption on weekdays was reduced an average of 54% relative to the initial condition. 10 refs., 14 figs., 3 tabs.

AUTOMATIC LIGHT CONTROL  

DOE Patents (OSTI)

A control system for a projection kinescope used in a facsimile scanning system and, in particular, meams for maintaining substantially constant the light emanating from the flying spot on the face of the kinescope are described. In general, the invention provides a feeler member disposed in such a position with respect to a projecting lens as to intercept a portion of the light striking the lens. Suitable circuitry in conjunction with a photomultiplier tube provides a signal proportional to the light intensity of the flying spot. The grid bias on the kinescope is controlled by this signal to maintain the intensity of the spot substantially constant.

Control circuit for automatic battery chargers  

SciTech Connect

An improved battery charger apparatus having a control circuit providing different charging periods which are automatically correlated with the type of battery connected to the charge for charging the connected battery to a preselected full charge state. The apparatus has a charging circuit for charging the battery, a sensing circuit for sensing the state of the battery during charging thereof by the charging circuit and a circuit for determining first and second predetermined reference voltage/current states. The apparatus causes the charging of the battery at a preselected initial charging level for an initial time period and establishes a first finish time period. The apparatus further determines a first time at which the state of the battery reaches the first predetermined referenced voltage/current state during the initial time period, and causes the charging circuit to continue to charge the battery at a preselected first charging level after the determination of the first time for a first finish time period. The apparatus further establishes a second finish time period and determines a second time at which the state of the battery reaches the second predetermined referenced voltage/current state during the first finish time period. The apparatus terminates charging of the battery if the state of the battery does not reach the second predetermined referenced voltage/current state during the first finish time period, and causes the charging circuit to continue to charge the battery at a preselected second charging level after the determination of the second time for a second finish time period.

Automatic control and management of electrostatic precipitator  

Science Conference Proceedings (OSTI)

The efficient operation of an electrostatic precipitator (ESP) in practice depends upon many variables, such as charging method, particle size, gas flow, temperature, dust resistivity, etc. With the air pollution control requirements becoming increasingly stringent, it is essential to closely monitor and accurately control the key parameters of an ESP control system. The efficient functioning of an ESP normally means minimizing power consumption and maximizing dust collection. Several control strategies can be adopted to meet this broad requirement. In this paper, a distributed control technique of an ESP, which uses the actual dust emission and boiler load as feedback inputs has been explained. The Electrostatic Precipitator Management System, which is a system designed by Bharat Heavy Electricals Ltd., Hyderabad, India, to meet the above control strategies using the distributed architecture to achieve efficient ESP operation is also described.

Closed loop computer control for an automatic transmission  

DOE Patents (OSTI)

In an automotive vehicle having an automatic transmission that driveably connects a power source to the driving wheels, a method to control the application of hydraulic pressure to a clutch, whose engagement produces an upshift and whose disengagement produces a downshift, the speed of the power source, and the output torque of the transmission. The transmission output shaft torque and the power source speed are the controlled variables. The commanded power source torque and commanded hydraulic pressure supplied to the clutch are the control variables. A mathematical model is formulated that describes the kinematics and dynamics of the powertrain before, during and after a gear shift. The model represents the operating characteristics of each component and the structural arrangement of the components within the transmission being controlled. Next, a close loop feedback control is developed to determine the proper control law or compensation strategy to achieve an acceptably smooth gear ratio change, one in which the output torque disturbance is kept to a minimum and the duration of the shift is minimized. Then a computer algorithm simulating the shift dynamics employing the mathematical model is used to study the effects of changes in the values of the parameters established from a closed loop control of the clutch hydraulic and the power source torque on the shift quality. This computer simulation is used also to establish possible shift control strategies. The shift strategies determined from the prior step are reduced to an algorithm executed by a computer to control the operation of the power source and the transmission.

Computer controlled synchronous shifting of an automatic transmission  

DOE Patents (OSTI)

A multiple forward speed automatic transmission produces its lowest forward speed ratio when a hydraulic clutch and hydraulic brake are disengaged and a one-way clutch connects a ring gear to the transmission casing. Second forward speed ratio results when the hydraulic clutch is engaged to connect the ring gear to the planetary carrier of a second gear set. Reverse drive and regenerative operation result when an hydraulic brake fixes the planetary and the direction of power flow is reversed. Various sensors produce signals representing the torque at the output of the transmission or drive wheels, the speed of the power source, and the hydraulic pressure applied to a clutch and brake. A control algorithm produces input data representing a commanded upshift, a commanded downshift, a commanded transmission output torque, and commanded power source speed. A microprocessor processes the inputs and produces a response to them in accordance with the execution of a control algorithm. Output or response signals cause selective engagement and disengagement of the clutch and brake at a rate that satisfies the requirements for a short gear ratio change and smooth torque transfer between the friction elements.

Automatic lighting controls demonstration: Long-term results  

SciTech Connect

An advanced electronically ballasted lighting control system was installed in a portion of an office building to measure the energy and demand savings. The lighting control system used an integrated lighting control scenario that included daylight following, lumen depreciation correction, and scheduling. The system reduced lighting energy on weekdays by 62% and 51% in the north and south daylit zones, respectively, compared to a reference zone that did not have controls. During the summer, over 75% energy savings were achieved on weekdays in the north daylit zone. Even in the south interior zone, which benefitted lime from daylight, correction strategies and adjustment of the aisleway lights to a low level resulted in energy use of only half that of the reference zone. Although, in general, the savings varied over the year due to changing daylight conditions, the energy reduction achieved with controls could be fit using a simple analytical model. Significant savings also occurred during core operating hours when it is more expensive to supply and use energy. Compared to the usage in the reference zone, energy reductions of 49%, 44%, and 62% were measured in the south daylight, south interior, and north daylight zones, respectively, during core operating hours throughout the year. Lighting energy usage on weekends decreased dramatically in the zones with controls, with the usage in the north daylit zone only 10% that of the reference zone. A simple survey developed to assess occupant response to the lighting control system showed that the occupants were satisfied with the light levels provided.

Automatic IEEE 802.11 rate control for streaming applications  

E-Print Network (OSTI)

Streaming multimedia content in real-time over a wireless link is a challenging task because of the rapid fluctuations in link conditions that can occur due to movement, interference, and so on. The popular IEEE 802.11 standard includes low-level tuning parameters like the transmission rate. Standard device drivers for today’s wireless products are based on gathering statistics, and consequently, adapt rather slowly to changes in conditions. To meet the strict latency requirements of streaming applications, we designed and implemented an advanced hybrid control algorithm that uses signal-strength (SNR) information to achieve fast responses. Since SNR readings are quite noisy we do not use that information to directly control the rate setting, but rather as a safeguard limiting the range of feasible settings to choose from. We report on real-time experiments involving two laptops equipped with IEEE 802.11a wireless interface cards. The results show that using SNR information greatly enhances responsiveness in comparison to statistics-based rate controllers. Finally, we will present the results of an experiment with realtime video streaming to a moving laptop in an office-like environment. Our hybrid control algorithm effectively prevented many packets losses, thereby achieving a much higher video quality than 1 the statistics based algorithm.

A field demonstration of automatic restroom ventilation control to reduce energy consumption  

SciTech Connect

This report documents the motion sensor evaluation task for the Hanford Energy Management Committee (HEMC) performed by Pacific Northwest Laboratory (PNL) to support the energy reduction mission. The study included installing automatic exhaust ventilation controls in the restrooms of the 1103 Building, 100N area. The goal of this task was to measure the benefit of automatically controlling exhaust ventilation in restrooms of an office building on the Hanford Site. The HEMC belief is that the value of controlling the fans is not limited to the power consumed by the fans, but also includes the value invested to condition (heat or cool) the makeup air. The air exhausted to the exterior of the building must ultimately be replaced by unconditioned air from the outside. This outside air must then by conditioned to maintain the comfort of building occupants. 6 figs., 1 tab.

Service- and energy-related optimization of advanced automatic train control  

DOE Green Energy (OSTI)

The Bay Area Rapid Transit (BART) system, in collaboration with Hughes Aircraft Company and Harmon Industries, is in the process of developing an Advanced Automatic Train Control (AATC) system to replace the current fixed-block automatic system. As in the current ATC system, the trains will be controlled by station computers at the wayside; however, spread-spectrum radios rather than track-circuits will be employed to determine train locations and reliably transfer control information, allowing for finer speed and acceleration control, as well as more precise train locating capabilities and moving-block control. The authors have developed a simulator of the train control and power consumption of the AATC system, and are now employing this tool to develop enhanced train control algorithms to supplement the safety-critical controller. These algorithms do not attempt to globally optimize the control system with respect to a cost function, but rather they modify the baseline vital control to smooth the train trajectories, and to reduce energy consumption and power infrastructure requirements, through coordination of multiple trains. Several control algorithms are under development, including (1) delay recovery, which smoothly and efficiently controls trains approaching and stopped behind a delayed train, (2) interference management, which controls closely-following trains to avoid oscillatory brake/acceleration cycles, and (3) low voltage avoidance, which limits power consumption by multiple trains in an area to prevent low voltage events. The authors discuss progress to date on development of these control algorithms, as well as their service- and energy-related benefits.

A Novel Approach for Automatic Control of Piezoelectric Elements Used for Lorentz Force Detuning Compensation  

E-Print Network (OSTI)

Abstract: Linear accelerators such as Free Electron Lasers (FELs) use superconducting (SC) resonant cavities to accelerate electron beam to high energies. TESLA type resonators are extremely sensitive to detuning induced by mechanical deformations – Lorentz force detuning (LFD), mainly due to the extremely high quality factor (Q) of the 1.3 GHz resonance mode, in the range of 1e6. The resulting modulation of a resonance frequency of the cavity makes power consumption and stability performances of the Low-Latency Radio Frequency (LLRF) control more critical. In order to minimize the RF control efforts and desired stabilities, the fast piezoelectric actuators with digital control systems are commonly used. The paper presents a novel approach for automatic control of piezoelectric actuators used for compensation of Lorentz force detuning, the practical application and carried out tests in accelerating module ACC6 in Free-Electron Laser in Hamburg (FLASH).

A controller for automatically regulating the supply of secondary combustion air to woodstoves and small furnaces. The controller includes a movable air valve for controlling the amount of secondary air admitted into the chamber. A self powered means monitors the concentration of combustible gases and vapors and actuates the movable air valve to increase the supply of secondary air in response to increasing concentrations of the combustible gases and vapors. The self-powered means can be two fluid filled sensor bulbs, one of which has a coating of a combustion catalyst. Alternatively, the self powered means can be two metallic stripes laminated together, one of which is coated with a combustion catalyst, and when heated, causes the air valve to actuate.

The Quantum Governor: Automatic quantum control and reduction of the influence of noise without measuring  

E-Print Network (OSTI)

The problem of automatically protecting a quantum system against noise in a closed circuit is analyzed. A general scheme is developed built from two steps. At first, a distillation step is induced in which undesired components are removed to another degree of freedom of the system. Later a recovering step is employed which the system gains back its initial density. An Optimal-Control method is used to generate the distilling operator. The scheme is demonstrated by a simulation of a two level byte influenced by white noise. Undesired deviations from the target were shown to be reduced by at least two orders of magnitude on average. The relations between the quantum version of the classical Watt's Governor and the field of quantum information are also discussed.

Automatic lighting controls demonstration: Long-term results. Final report, July 1991  

SciTech Connect

An advanced electronically ballasted lighting control system was installed in a portion of an office building to measure the energy and demand savings. The lighting control system used an integrated lighting control scenario that included daylight following, lumen depreciation correction, and scheduling. The system reduced lighting energy on weekdays by 62% and 51% in the north and south daylit zones, respectively, compared to a reference zone that did not have controls. During the summer, over 75% energy savings were achieved on weekdays in the north daylit zone. Even in the south interior zone, which benefitted lime from daylight, correction strategies and adjustment of the aisleway lights to a low level resulted in energy use of only half that of the reference zone. Although, in general, the savings varied over the year due to changing daylight conditions, the energy reduction achieved with controls could be fit using a simple analytical model. Significant savings also occurred during core operating hours when it is more expensive to supply and use energy. Compared to the usage in the reference zone, energy reductions of 49%, 44%, and 62% were measured in the south daylight, south interior, and north daylight zones, respectively, during core operating hours throughout the year. Lighting energy usage on weekends decreased dramatically in the zones with controls, with the usage in the north daylit zone only 10% that of the reference zone. A simple survey developed to assess occupant response to the lighting control system showed that the occupants were satisfied with the light levels provided.

Solar powered automatic turn-on control (spa-toc) unit and method  

SciTech Connect

Orderly control of power applied by a photovoltaic solar panel d.c. source to a load is attained despite varying long and short term solar conditions by coupling power from the panel to an inverter in response to the panel voltage exceeding a predetermined level and preventing coupling of power from the panel to the inverter in response to the panel voltage being less than a predetermined level. The switching frequency of the inverter is controlled in response to the panel voltage so that approximately maximum power which the panel is capable of generating is supplied to the inverter for the incident solar energy on the panel at a given temperature. Power is supplied to the inverter by a series switch between the panel and inverter. The switch is activated into a conducting state in response to the panel voltage exceeding a predetermined value. The panel voltage controls the turn-on and turn-off levels of the series switch by a hysteresis effect, provided by connecting a dummy power dissipating load in shunt with the panel while the series switch is cut off. The dummy load has a value causing the panel output voltage to be less than the voltage for maximum panel output power. A similar series switch and hysteresis control is provided for control circuitry for the inverter. The series switch for supplying power to the control circuitry can be activated in response to the same voltage which activates the series switch for the inverter, or in response to a different voltage level.

AUTOMATIC COUNTER  

DOE Patents (OSTI)

An automatic counter of alpha particle tracks recorded by a sensitive emulsion of a photographic plate is described. The counter includes a source of mcdulated dark-field illumination for developing light flashes from the recorded particle tracks as the photographic plate is automatically scanned in narrow strips. Photoelectric means convert the light flashes to proportional current pulses for application to an electronic counting circuit. Photoelectric means are further provided for developing a phase reference signal from the photographic plate in such a manner that signals arising from particle tracks not parallel to the edge of the plate are out of phase with the reference signal. The counting circuit includes provision for rejecting the out-of-phase signals resulting from unoriented tracks as well as signals resulting from spurious marks on the plate such as scratches, dust or grain clumpings, etc. The output of the circuit is hence indicative only of the tracks that would be counted by a human operator.

The Use of Automatic Wire Coding to Evaluate Control Selection Bias in the Savitz et al. Study  

Science Conference Proceedings (OSTI)

One possible explanation of the association between wire codes and childhood cancer is that selecting controls using random digit dialing techniques may have resulted in controls that were not representative of the population from which the cases arose. An under-representation of controls in the highest wire code category could have created the appearance of an association between that category and childhood cancer. The project was designed to evaluate this possibility in the Savitz et al. study in Denver.

The Lightspeed Automatic . . .  

E-Print Network (OSTI)

We present an automated approach for high-quality preview of feature-film rendering during lighting design. Similar to previous work, we use a deep-framebuffer shaded on the GPU to achieve interactive performance. Our first contribution is to generate the deep-framebuffer and corresponding shaders automatically through data-flow analysis and compilation of the original scene. Cache compression reduces automatically-generated deep-framebuffers to reasonable size for complex production scenes and shaders. We also propose a new structure, the indirect framebuffer, that decouples shading samples from final pixels and allows a deep-framebuffer to handle antialiasing, motion blur and transparency efficiently. Progressive refinement enables fast feedback at coarser resolution. We demonstrate our approach in real-world production.

Automatic Electric Load Identification in  

E-Print Network (OSTI)

Abstract — A microgrid is the power system of choice for the electrification of rural areas in developing countries. It should be able to adapt to changing load situations without the need for specialists to change the configuration of the microgrid controller. This paper proposes a self-configuring microgrid management system that is able to adjust both generation and demand of the system, so that also in case of growing electricity demand the grid can still be operable by disconnecting unessential loads. A crucial task for the microgrid controller is to automatically identify the connected loads on the basis of their consumption behaviors. For this, a template-matching algorithm is proposed that is based on Dynamic Time Warping, which is primarily used in speech recognition. It has been found that for load profile analysis, simple signal features such as the number of rising edges or the aggregated energy consumption in a given time window is sufficient to describe the signal. In contrast to speech recognition, frequency domain analysis is not necessary.

Automatic Parallel Parking and Returning to Traffic Maneuvers  

E-Print Network (OSTI)

This video illustrates a control approach developed to perform parallel parking and returning to traffic maneuvers for a car capable of autonomous motion. The key idea is to carry out a motion control procedure involving a "Localization-Planning-Execution" cycle until a specified location of the car relative to its environment is reached. Range measurements are used to model environmental objects around the car. The automatic maneuvers developed are demonstrated on an experimental electric autonomous car in a usual traffic environment. 1 Introduction Many drivers have difficulties or make errors while parallel parking or in pulling out of a parking place. A control approach to automatic parallel parking and pulling out maneuvers has been developed and tested on an experimental electric car capable of autonomous motion.

ADOMIT is an algorithm for Automatic Detection of OMissions in Translations. The algorithm relies solely on geometric analysis of bitext maps and uses no linguistic informatlon. This property allows it to deal equally well with omissions that do not correspond to linguistic units, such as might resuit fi'om word-processing mishaps. ADOMIT has proven itself by discovering many errors in a handconstructed gold standard for evaluating bitext mapping algorithms. Quantitative evaluation on simulated omissions showed that, even with today's poor bitext mapping technology, ADOMIT is a valuable quality control tool for translators and translation bureaus.

Automatic flue gas heat recovery system  

Science Conference Proceedings (OSTI)

An automatic flue gas heat recovery system for supplementing or replacing a conventional, separate hot water system. In the example described, the heat recovery system is applied to a pizza restaurant where large quantities of heat energy are normally wasted up an oven chimney stack, and large quantities of hot water also are required for restaurant operations. An electric motor driven pump circulates water in a closed loop between a storage tank and a heat exchanger tube located in the oven chimney stack. A thermostat control automatically starts the pump when the oven heats the chimney stack to an effective water heating temperature. When temperature in the storage tank reaches a predetermined maximum, the thermostat control stops the pump, opens a drain valve, and dumps water quickly and completely from the heat exchanger tube. Three different embodiments are shown and described illustrating systems with one or more storage tanks and one or more pumps. In the plural storage tank embodiments, an existing hot water heating tank may be converted for use to augment a main tank supplied with the present system.

Hybrid approach is employed to establish a commissioning and re-commissioning tool of VAV air-conditioning system. Performance indices with expert rules based on system physical characteristics are adopted to detect and diagnose the nine of the ten faults. PCA (Principal Component Analysis) method is developed to detect and diagnose the VAV box flow sensor bias (Fault 10) and to reconstruct the faulty sensors. A multiple VAV fault FDD strategy for a VAV entire system is developed, which is validated in simulation and filed tests.

Automatic Exploration of Datacenter performance Regimes  

E-Print Network (OSTI)

Horizontally scalable Internet services present an opportunity to use automatic resource allocation strategies for system management in the datacenter. In most of the previous work, a controller employs a performance model of the system to make decisions about the optimal allocation of resources. However, these models are usually trained offline or on a small-scale deployment and will not accurately capture the performance of the controlled application. To achieve accurate control of the web application, the models need to be trained directly on the production system and adapted to changes in workload and performance of the application. In this paper we propose to train the performance model using an exploration policy that quickly collects data from different performance regimes of the application. The goal of our approach for managing the exploration process is to strike a balance between not violating the performance SLAs and the need to collect sufficient data to train an accurate performance model, which requires pushing the system close to its capacity. We show that by using our exploration policy, we can train a performance model of a Web 2.0 application in less than an hour and then immediately use the model in a resource allocation controller.

Requirements for Automatically Generating Multi-Modal Interfaces for Complex Appliances  

E-Print Network (OSTI)

Several industrial and academic research groups are working to simplify the control of appliances and services by creating a truly universal remote control. Unlike the preprogrammed remote controls available today, these new controllers download a specification from the appliance or service and use it to automatically generate a remote control interface. This promises to be a useful approach because the specification can be made detailed enough to generate both speech and graphical interfaces. Unfortunately, generating good user interfaces can be difficult. Based on user studies and prototype implementations, this paper presents a set of requirements that we have found are needed for automatic interface generation systems to create high-quality user interfaces.

Attacking Automatic Wireless Network Selection  

E-Print Network (OSTI)

Wireless 802.11 networking is becoming so prevalent that many users have become accustomed to having available wireless networks in their workplace, home, and many public places such as airports and coffee shops. Modern client operating systems implement automatic wireless network discovery and known network identification to facilitate wireless networking for the end-user. In order to implement known network discovery, client operating systems remember past wireless networks that have been joined and automatically look for these networks (referred to as Preferred or Trusted Networks) whenever the wireless network adapter is enabled. By examining these implementations in detail, we have discovered previously undisclosed vulnerabilities in the implementation of these algorithms under the two most prevalent client operating systems, Windows XP and MacOS X. With custom base station software, an attacker may cause clients within wireless radio range to associate to the attacker’s wireless network without user interaction or notification. This will occur even if the user has never connected to a wireless network before or they have an empty Preferred/Trusted Networks List. We describe these vulnerabilities as well as their implementation and impact. 1

Automatic camera tracking for remote manipulators  

SciTech Connect

The problem of automatic camera tracking of mobile objects is addressed with specific reference to remote manipulators and using either fixed or mobile cameras. The technique uses a kinematic approach employing 4 x 4 coordinate transformation matrices to solve for the needed camera PAN and TILT angles. No vision feedback systems are used, as the required input data are obtained entirely from position sensors from the manipulator and the camera-positioning system. All hardware requirements are generally satisfied by currently available remote manipulator systems with a supervisory computer. The system discussed here implements linear plus on/off (bang-bang) closed-loop control with a +-2-deg deadband. The deadband area is desirable to avoid operator seasickness caused by continuous camera movement. Programming considerations for camera control, including operator interface options, are discussed. The example problem presented is based on an actual implementation using a PDP 11/34 computer, a TeleOperator Systems SM-229 manipulator, and an Oak Ridge National Laboratory (ORNL) camera-positioning system. 3 references, 6 figures, 2 tables.

Automatic tool path generation for finish machining  

SciTech Connect

A system for automatic tool path generation was developed at Sandia National Laboratories for finish machining operations. The system consists of a commercially available 5-axis milling machine controlled by Sandia developed software. This system was used to remove overspray on cast turbine blades. A laser-based, structured-light sensor, mounted on a tool holder, is used to collect 3D data points around the surface of the turbine blade. Using the digitized model of the blade, a tool path is generated which will drive a 0.375 inch diameter CBN grinding pin around the tip of the blade. A fuzzified digital filter was developed to properly eliminate false sensor readings caused by burrs, holes and overspray. The digital filter was found to successfully generate the correct tool path for a blade with intentionally scanned holes and defects. The fuzzified filter improved the computation efficiency by a factor of 25. For application to general parts, an adaptive scanning algorithm was developed and presented with simulation results. A right pyramid and an ellipsoid were scanned successfully with the adaptive algorithm.

Ekofisk automatic GPS subsidence measurements  

Science Conference Proceedings (OSTI)

A fully automatic GPS satellite-based procedure for the reliable measurement of subsidence of several platforms in almost real time is described. Measurements are made continuously on platforms in the North Sea Ekofisk Field area. The procedure also yields rate measurements, which are also essential for confirming platform safety, planning of remedial work, and verification of subsidence models. GPS measurements are more attractive than seabed pressure-gauge-based platform subsidence measurements-they are much cheaper to install and maintain and not subject to gauge drift. GPS measurements were coupled to oceanographic quantities such as the platform deck clearance, which leads to less complex offshore survey procedures. Ekofisk is an oil and gas field in the southern portion of the Norwegian North Sea. Late in 1984, it was noticed that the Ekofisk platform decks were closer to the sea surface than when the platforms were installed-subsidence was the only logical explanation. After the subsidence phenomenon was recognized, an accurate measurement method was needed to measure progression of subsidence and the associated subsidence rate. One available system for which no further development was needed, was the NAVSTAR GPS-measurements started in March 1985.

Personal Universal Controllers: Controlling Complex Appliances with . . .  

E-Print Network (OSTI)

We envision a future where each person will carry with them a personal universal controller (PUC), a portable computerized device that allows the user to control any appliance within their environment. The PUC has a two-way communication channel with each appliance. It downloads a specification of the appliance's features and then automatically generates an interface for controlling that appliance (graphical, speech, or both). In this demonstration we present a working PUC system that automatically generates graphical and speech interfaces, and controls real appliances, including a shelf stereo and a Sony camcorder.

Pilot Study: Measurement of Room Illuminance to Assess Automatic Brightness  

NLE Websites -- All DOE Office Websites (Extended Search)

Study: Measurement of Room Illuminance to Assess Automatic Brightness Study: Measurement of Room Illuminance to Assess Automatic Brightness Control in Televisions Title Pilot Study: Measurement of Room Illuminance to Assess Automatic Brightness Control in Televisions Publication Type Conference Proceedings Year of Publication 2012 Authors Greenblatt, Jeffery B., Mia Forbes Pirie, Louis-Benoit Desroches, Sally M. Donovan, Clancy Donnelly, Craig Billingsley, and Chris Calwell Pagination 13 Date Published August 12 Conference Location Berkeley Abstract Automatic brightness control (ABC) is an increasingly common feature found in newtelevisions (TVs) and computer monitors. ABC is intended to adjust TV screen brightness(luminance) according to the ambient light level (room illuminance). When implementedcorrectly, this can both reduce energy consumption and improve viewing quality. The currentENERGY STAR test procedure provides for a more favorable energy use rating for TVs withABC, by measuring power consumption at two light levels (0 and 300 lux) and reporting aweighted-average energy use. However, this and other studies suggest that these levels are notrepresentative of actual TV viewing conditions.As there were currently only limited data available concerning room illuminance, weundertook a small pilot study in 2011 to begin to answer two key questions: 1. To what extent doroom illuminance levels vary depending on the location of measurement (e.g., center of theroom, on the couch, or at the TV)? 2. What room illuminance conditions are prevalent whenpeople watch TV?We measured room illuminance in the homes of nine volunteers in California andColorado to begin addressing the above two questions. Although the study had the usualdrawbacks of a pilot (limited sample size, time duration, etc.), it has, nonetheless, yielded usefulresults. The study shows definitively that there is large variability between measurements madeat different locations in the room and, therefore, that location of room illuminance measurementsis critical. Moreover, the majority (over 75%) of TV viewing occurred at illuminance levels ofless than 50 lux (though measurements of up to several hundred lux were also recorded), a resultthat was consistent with subsequent larger-scale studies. This type of information can helpdetermine how ABC-enabled TVs should be tested to best represent actual viewing conditions.

Automatic Projector Calibration with Embedded Light Sensors  

E-Print Network (OSTI)

Projection technology typically places several constraints on the geometric relationship between the projector and the projection surface to obtain an undistorted, properly sized image. In this paper we describe a simple, robust, fast, and low-cost method for automatic projector calibration that eliminates many of these constraints. We embed light sensors in the target surface, project Gray-coded binary patterns to discover the sensor locations, and then prewarp the image to accurately fit the physical features of the projection surface. This technique can be expanded to automatically stitch multiple projectors, calibrate onto nonplanar surfaces for object decoration, and provide a method for simple geometry acquisition.

Automatic History Matching of Geothermal Field Performance  

DOE Green Energy (OSTI)

We have developed inverse modeling capabilities for the multiphase multicomponent numerical simulator TOUGH2 to facilitate automatic history matching and parameter estimation based on data obtained during exploitation of geothermal fields. The ITOUGH2 code allows one to estimate TOUGH2 input parameters based on any type of observation for which a corresponding TOUGH2 output can be calculated. Furthermore, a detailed residual and error analysis is performed, and the uncertainty of model predictions can be evaluated. This paper focuses on the solution of the inverse problem, i.e. the determination of model-related parameters by automatically calibrating a conceptual model of the geothermal system against data obtained during field operation. We first describe the modeling approach used to simulate fluid and heat flow in fractured-porous media. The inverse problem is then formulated, followed by a brief discussion of the optimization algorithm. A sample problem is given to demonstrate the application of the method to geothermal reservoir data.

Natural Statistical Models for Automatic Speech Recognition  

E-Print Network (OSTI)

The performance of state-of-the-art speech recognition systems is still far worse than that of humans. This is partly caused by the use of poor statistical models. In a general statistical pattern classification task, the probabilistic models should represent the statistical structure unique to and distinguishing those objects to be classified. In many cases, however, model families are selected without verification of their ability to represent vital discriminative properties. For example, Hidden Markov Models (HMMs) are frequently used in automatic speech recognition systems even though they possess conditional independence properties that might cause inaccuracies when modeling and classifying speech signals. In this work, a new method for automatic speech recognition is developed where the natural statistical properties of speech are used to determine the probabilistic model. Starting from an HMM, new models are created by adding dependencies only if they are not already well captured by the HMM, and only if they increase the

Automatic Sequences and Zip-Specifications  

E-Print Network (OSTI)

We consider infinite sequences of symbols, also known as streams, and the decidability question for equality of streams defined in a restricted format. This restricted format consists of prefixing a symbol at the head of a stream, of the stream function `zip', and recursion variables. Here `zip' interleaves the elements of two streams in alternating order, starting with the first stream. For example, the Thue-Morse sequence is obtained by the `zip-specification' {M = 0 : X, X = 1 : zip(X,Y), Y = 0 : zip(Y,X)}. Our analysis of such systems employs both term rewriting and coalgebraic techniques. We establish decidability for these zip-specifications, employing bisimilarity of observation graphs based on a suitably chosen cobasis. The importance of zip-specifications resides in their intimate connection with automatic sequences. We establish a new and simple characterization of automatic sequences. Thus we obtain for the binary zip that a stream is 2-automatic iff its observation graph using the cobasis (hd,even...

The construction of a reference ontology for a large domain still remains an hard human task. The process is sometimes assisted by software tools that facilitate the information extraction from a textual corpus. Despite of the great use of XML Schema files on the internet and especially in the B2B domain, tools that offer a complete semantic analysis of XML schemas are really rare. In this paper we introduce Janus, a tool for automatically building a reference knowledge base starting from XML Schema files. Janus also provides different useful views to simplify B2B application integration.

Sensor-based navigation of a mobile robot using automatically constructed fuzzy rules  

SciTech Connect

A system for automatic generation of fuzzy rules is proposed which is based on a new approach, called ``Fuzzy Behaviorist,`` and on its associated formalism for rule base development in behavior-based robot control systems. The automated generator of fuzzy rules automatically constructs the set of rules and the associated membership functions that implement reasoning schemes that have been expressed in qualitative terms. The system also checks for completeness of the rule base and independence and/or redundancy of the rules to ensure that the requirements of the formalism are satisfied. Examples of the automatic generation of fuzzy rules for cases involving suppression and/or inhibition of fuzzy behaviors are given and discussed. Experimental results obtained with the automated fuzzy rule generator applied to the domain of sensor-based navigation in a priori unknown environments using one of our autonomous test-bed robots are then presented and discussed to illustrate the feasibility of large-scale automatic fuzzy rule generation using our proposed ``Fuzzy Behaviorist`` approach.

Automatic generation of executable communication specifications from parallel applications  

Science Conference Proceedings (OSTI)

Portable parallel benchmarks are widely used and highly effective for (a) the evaluation, analysis and procurement of high-performance computing (HPC) systems and (b) quantifying the potential benefits of porting applications for new hardware platforms. Yet, past techniques to synthetically parameterized hand-coded HPC benchmarks prove insufficient for today's rapidly-evolving scientific codes particularly when subject to multi-scale science modeling or when utilizing domain-specific libraries. To address these problems, this work contributes novel methods to automatically generate highly portable and customizable communication benchmarks from HPC applications. We utilize ScalaTrace, a lossless, yet scalable, parallel application tracing framework to collect selected aspects of the run-time behavior of HPC applications, including communication operations and execution time, while abstracting away the details of the computation proper. We subsequently generate benchmarks with identical run-time behavior from the collected traces. A unique feature of our approach is that we generate benchmarks in CONCEPTUAL, a domain-specific language that enables the expression of sophisticated communication patterns using a rich and easily understandable grammar yet compiles to ordinary C + MPI. Experimental results demonstrate that the generated benchmarks are able to preserve the run-time behavior - including both the communication pattern and the execution time - of the original applications. Such automated benchmark generation is particularly valuable for proprietary, export-controlled, or classified application codes: when supplied to a third party. Our auto-generated benchmarks ensure performance fidelity but without the risks associated with releasing the original code. This ability to automatically generate performance-accurate benchmarks from parallel applications is novel and without any precedence, to our knowledge.

Applications of automatic differentiation in CFD  

DOE Green Energy (OSTI)

Automated multidisciplinary design of aircraft requires the optimization of complex performance objectives with respect to a number of design parameters and constraints. The effect of these independent design variables on the system performance criteria can be quantified in terms of sensitivity derivatives for the individual discipline simulation codes. Typical advanced CFD codes do not provide such derivatives as part of a flow solution. These derivatives are expensive to obtain by divided differences from perturbed solutions, and may be unreliable, particularly for noisy functions. In this paper, automatic differentiation has been investigated as a means of extending iterative CFD codes with sensitivity derivatives. In particular, the ADIFOR automatic differentiator has been applied to the 3-D, thin-layer Navier-Stokes, multigrid flow solver called TLNS3D coupled with the WTCO wing grid generator. Results of a sequence of efforts in which TLNS3D has been successfully augmented to compute a variety of sensitivities are presented. It is shown that sensitivity derivatives can be obtained accurately and efficiently using ADIFOR, although significant advances are necessary for the efficiency of ADIFOR-generated derivative code to become truly competitive with hand-differentiated code.

Automatic CO/sub 2/ removal system and operation thereof  

SciTech Connect

A system is described for removing CO/sub 2/ from the manufactured process gas in an SNG manufacturing plant, the system operating the hot carbonate process wherein hot potassium carbonate solution absorbs CO/sub 2/ from the process gas under pressure in an absorber column and is regenerated by pressure reduction and steam stripping in a regenerator column and a reboiler before being returned to the absorber by a circulating pump. The system is completely automated and is controlled by a computer so that start-up, running and shut-down of the system is carried out automatically upon initiation by an operator, whereby the system is particularly suited for use in peak load SNG plants. For this purpose the system includes a solution make up tank, a solution storage tank, and a flushing water collection tank, preferably has all of its surfaces contacted by potassium carbonate solution made of stainless steel, and has sensors (F, L, T, P, AN, SG, and PH) and valve switches for transmitting information to the computer relating to the state of the system. The computer is programmed to operate the sequences of operation necessary to achieve the start-up, running and shut down of the system, operate loop controls on the solution levels in the absorber and regenerator columns, and on the rates of flow of solution to the absorber and of steam to the reboiler, and also to monitor the system parameters and to display data and signal alarm conditions.

Automatic tuning for linearly tunable filter  

E-Print Network (OSTI)

A new tuning scheme for linearly tunable high-Q filters is proposed. The tuning method is based on using the phase information for both frequency and Q factor tuning. There is no need to find out the relationship between a filter's passband magnitude and Q. A gm-C biquadratic filter is designed to demonstrate the proposed tuning circuitry. The project includes a phase locked loop (PLL) based frequency tuning loop, reference clock generator, and differential difference amplifier (DDA) for dealing with frequency and Q factor tuning loop and linearly tunable second order gm-C bandpass filter. Simulation results for a 10 MHz prototype filter using AMI 0.5?m process is presented. The chip testing results show that the automatic frequency tuning error is 2.5% for the 10 MHz case.

This paper describes a complete face tracking system that interprets human head movements in real time. The system combines motion analysis with reliable and efficient object recognition strategies. It classifies head movements as "yes" (nodding head), "no" (shaking head) or "nothing" (still head). The system's skill allows contactless man-machine interaction, thus giving access to a number of new applications. 1 Introduction As industrialization proceeds, the importance of interactions between man and machine increases rapidly. Information flow from machine to man has become comfortable and direct in recent years due to tremendous progresses in computer graphics. Information flow from man to machine, on the other hand, is still on a low level. It is restricted to moving mice, pressing buttons, and typing character sequences on a keyboard. Automatic interpretation of gestures and facial expressions could reduce this imbalance and is therefore of central interrest for current and futu...

An automatic analysis of Norwegian compounds  

E-Print Network (OSTI)

Introduction The University of Oslo is currently developing an automatic morphosyntactic tagger for Norwegian. 2 A very important module is one which can analyse compounds. Compounding is extremely productive in Norwegian, and it is futile to ever hope for a lexicon (dictionary) that will contain all or even most of the compounds that occr in actual texts. Since the tagger we are developing is based on the possibility of recognising words by the help of a lexicon, it is of great importance to have a module that recognises new compounds. According to Munthe (1972), 10.4 per cent of all words in running text are compounds. Any text sample will contain a greatnumber of compounds. This statistics is true even for small samples. I took an arbitrary 440-word article from the newspaper Aftenposten from September this year, Full penhet om passunion (Full openness on passport union), and I quickly counted 47 compounds.

Automatic registration of serial mammary gland sections  

SciTech Connect

We present two new methods for automatic registration of microscope images of consecutive tissue sections. They represent two possibilities for the first step in the 3-D reconstruction of histological structures from serially sectioned tissue blocks. The goal is to accurately align the sections in order to place every relevant shape contained in each image in front of its corresponding shape in the following section before detecting the structures of interest and rendering them in 3D. This is accomplished by finding the best rigid body transformation (translation and rotation) of the image being registered by maximizing a matching function based on the image content correlation. The first method makes use of the entire image information, whereas the second one uses only the information located at specific sites, as determined by the segmentation of the most relevant tissue structures. To reduce computing time, we use a multiresolution pyramidal approach that reaches the best registration transformation in increasing resolution steps. In each step, a subsampled version of the images is used. Both methods rely on a binary image which is a thresholded version of the Sobel gradients of the image (first method) or a set of boundaries manually or automatically obtained that define important histological structures of the sections. Then distance-transform of the binary image is computed. A proximity function is then calculated between the distance image of the image being registered and that of the reference image. The transformation providing a maximum of the proximity function is then used as the starting point of the following step. This is iterated until the registration error lies below a minimum value.

The paper describes the design, the implementation of a neural controller used in an automatic daylight control system. The automatic lighting control system (ALCS) attempt to maintain constant the illuminance at the desired level on working plane even if the daylight contribution is variable. Therefore, the daylight will represent the perturbation signal for the ALCS. The mathematical model of process is unknown. The applied structure of control need the inverse model of process. For this purpose it was used other artificial neural network (ANN) which identify the inverse model of process in an on-line manner. In fact, this ANN identify the inverse model of process + the perturbation signal. In this way the learning signal for neural controller has a better accuracy for the present application.

Automatic design of 3-d fixtures and assembly pallets  

Science Conference Proceedings (OSTI)

This paper presents an implemented algorithm that automatically designs fixtures and assembly pallets to hold three-dimensional parts. All fixtures generated by the algorithm employ round side locators, a side clamp, and cylindrical supports; depending on the value of an input control flag, the fixture may also include swing-arm top clamps. Using these modular elements, the algorithm designs fixtures that rigidly constrain and locate the part, obey task constraints, are robust to part shape variations, are easy to load, and are economical to produce. For the class of fixtures that are considered, the algorithm is guaranteed to find the global optimum design that satisfies these and other pragmatic conditions. The authors present the results of the algorithm applied to several practical manufacturing problems. For these complex problems the algorithm typically returns initial high-quality fixture designs in less than a minute, and identifies the global optimum design in just over an hour. The algorithm is also capable of solving difficult design problems where a single fixture is desired that can hold either of two parts.

DOE Patents (OSTI)

An automatic target recognition apparatus (10) is provided, having a video camera/digitizer (12) for producing a digitized image signal (20) representing an image containing therein objects which objects are to be recognized if they meet predefined criteria. The digitized image signal (20) is processed within a video analysis subroutine (22) residing in a computer (14) in a plurality of parallel analysis chains such that the objects are presumed to be lighter in shading than the background in the image in three of the chains and further such that the objects are presumed to be darker than the background in the other three chains. In two of the chains the objects are defined by surface texture analysis using texture filter operations. In another two of the chains the objects are defined by background subtraction operations. In yet another two of the chains the objects are defined by edge enhancement processes. In each of the analysis chains a calculation operation independently determines an error factor relating to the probability that the objects are of the type which should be recognized, and a probability calculation operation combines the results of the analysis chains.

EVALUATION OF AUTOMATIC DATA PROCESSING IN THE FLUORIDE VOLATILITY PILOT PLANT  

SciTech Connect

Automatic data logging and digital-computer techniques were evaluated in the ORNL Fluoride Volatiltty Pilot Plant, The data reduction sequence consisted of encoding plant signals from conventional instrumentation, digitizing the encoded signals with an on-line automatic data logger, and processing the logged data off-line with a digital computer. Data reduction and computational codes were useful in disseminating process data, with photographic curve plots being the most efficient means. Considerable difficulty was experienced with logger output errors, which complicated the data processing and frequently resulted in erroneous results. After continuous operation of the data-processing sequence for 12 months it was concluded that output from a data logger is of limited use without recourse to a computer, loading of raw logger data to the computer and subsequent conversion to a useful form (engineering units) can account for up to 70% of total computer charges, and some backup to automatic data logging, either as continuous or manual recording, may be desirable because logger downtime may be as much as 5%. The use of the data reduction sequence will be continued in the pilot plant. Expanding the sequence to include on-line computation and process control features is not justified because of process limitations. (auth)

Energy conserving automatic light output system  

SciTech Connect

An energy conserving lighting system is provided wherein a plurality of fluorescent lamps are powered by a poorly regulated voltage source power supply which provides a decreasing supply voltage with increasing arc current so as to generally match the volt-ampere characteristics of the lamps. A transistor ballast and control circuit connected in the arc current path controls the arc current, and hence the light output, in accordance with the total ambient light, i.e., the light produced by the lamps together with whatever further light is produced by other sources such as daylight. In another embodiment, a transistor ballast is utilized in combination with an inductive ballast. The transistor ballast provides current control over a wide dynamic range up to a design current maximum at which maximum the transistor is saturated and the inductive ballast takes over the current limiting function. An operational amplifier is preferably connected in the base biassing circuit of the control transistor of the transistor ballast. In an embodiment wherein two sets of lamps with separate inductive ballasts are provided, the arc currents for the two ballasts are scaled or matched to provide the desired light output.

Sounds great, but I know when I'm rushing out the door, the last thing on my mind is turning down the thermostat. Luckily, programmable thermostats make it easy to save without much effort. In fact, once you get the thermostat installed and programmed to your schedule, you can stop thinking about it; your home is programmed to save. First, decide what to set your thermostat at when you are home and awake; 68°F is a good guideline in the winter. From there, program the thermostat

Automatic image alignment for 3d environment modeling  

E-Print Network (OSTI)

We describe an approach for automatically registering color images with 3D laser scanned models. We use the chisquare statistic to compare color images to polygonal models texture mapped with acquired laser reflectance values. In complicated scenes we find that the chi-square test is not robust enough to permit an automatic global registration approach. Therefore, we introduce two techniques for obtaining initial pose estimates that correspond to a coarse alignment of the data. The first method is based on rigidly attaching a camera to a laser scanner and the second utilizes object tracking to decouple these imaging devices. The pose estimates serve as an initial guess for our optimization method, which maximizes the chi-square statistic over a local space of transformations in order to automatically determine the proper alignment. 1.

Gaze-Based Interaction for Semi-Automatic Photo Cropping  

E-Print Network (OSTI)

We present an interactive method for cropping photographs given minimal information about the location of important content, provided by eye tracking. Cropping is formulated in a general optimization framework that facilitates adding new composition rules, as well as adapting the system to particular applications. Our system uses fixation data to identify important content and compute the best crop for any given aspect ratio or size, enabling applications such as automatic snapshot recomposition, adaptive documents, and thumbnailing. We validate our approach with studies in which users compare our crops to ones produced by hand and by a completely automatic approach. Experiments show that viewers prefer our gaze-based crops to uncropped images and fully automatic crops.

Automatic Bayesian inference for LISA data analysis strategies  

E-Print Network (OSTI)

We demonstrate the use of automatic Bayesian inference for the analysis of LISA data sets. In particular we describe a new automatic Reversible Jump Markov Chain Monte Carlo method to evaluate the posterior probability density functions of the a priori unknown number of parameters that describe the gravitational wave signals present in the data. We apply the algorithm to a simulated LISA data set containing overlapping signals from white dwarf binary systems (DWD) and to a separate data set containing a signal from an extreme mass ratio inspiral (EMRI). We demonstrate that the approach works well in both cases and can be regarded as a viable approach to tackle LISA data analysis challenges.

2011 Status of the Automatic Alignment System for the National Ignition Facility  

SciTech Connect

Automated alignment for the National Ignition Facility (NIF) is accomplished using a large-scale parallel control system that directs 192 laser beams along the 300-m optical path. The beams are then focused down to a 50-micron spot in the middle of the target chamber. The entire process is completed in less than 50 minutes. The alignment system commands 9,000 stepping motors for highly accurate adjustment of mirrors and other optics. 41 control loops per beamline perform parallel processing services running on a LINUX cluster to analyze high-resolution images of the beams and their references. This paper describes the status the NIF automatic alignment system and the challenges encountered as NIF development has transitioned from building the laser, to becoming a research project supporting a 24 hour, 7 day laser facility. NIF is now a continuously operated system where performance monitoring is increasingly more critical for operation, maintenance, and commissioning tasks. Equipment wear and the effects of high energy neutrons from fusion experiments are issues which alter alignment efficiency and accuracy. New sensors needing automatic alignment assistance are common. System modifications to improve efficiency and accuracy are prevalent. Handling these evolving alignment and maintenance needs while minimizing the impact on NIF experiment schedule is expected to be an on-going challenge for the planned 30 year operational life of NIF.

Methods for automatically evaluating answers to complex questions  

E-Print Network (OSTI)

Evaluation is a major driving force in advancing the state of the art in language technologies. In particular, methods for automatically assessing the quality of machine output is the preferred method for measuring progress, provided that these metrics have been validated against human judgments. Following recent developments in the automatic evaluation of machine translation and document summarization, we present a similar approach, implemented in a measure called Pourpre, an automatic technique for evaluating answers to complex questions based on n-gram co-occurrences between machine output and a human-generated answer key. Until now, the only way to assess the correctness of answers to such questions involves manual determination of whether an information “nugget ” appears in a system’s response. The lack of automatic methods for scoring system output is an impediment to progress in the field, which we address with this work. Experiments with the TREC 2003, TREC 2004, and TREC 2005 QA tracks indicate that rankings produced by our metric correlate highly with official rankings, and that Pourpre outperforms direct application of existing metrics. 1

Automatic discovery of query-classdependent models for multimodal search  

E-Print Network (OSTI)

We develop a framework for the automatic discovery of query classes for query-class-dependent search models in multimodal retrieval. The framework automatically discovers useful query classes by clustering queries in a training set according to the performance of various unimodal search methods, yielding classes of queries which have similar fusion strategies for the combination of unimodal components for multimodal search. We further combine these performance features with the semantic features of the queries during clustering in order to make discovered classes meaningful. The inclusion of the semantic space also makes it possible to choose the correct class for new, unseen queries, which have unknown performance space features. We evaluate the system against the TRECVID 2004 automatic video search task and find that the automatically discovered query classes give an improvement of 18% in MAP over hand-defined query classes used in previous works. We also find that some hand-defined query classes, such as “Named Person ” and “Sports ” do, indeed, have similarities in search method performance and are useful for query-class-dependent multimodal search, while other hand-defined classes, such as “Named Object” and “General Object” do not have consistent search method performance and should be split apart or replaced with other classes.

REACTOR CONTROL  

DOE Patents (OSTI)

This patent relates to nuclear reactors of the type which utilize elongited rod type fuel elements immersed in a liquid moderator and shows a design whereby control of the chain reaction is obtained by varying the amount of moderator or reflector material. A central tank for containing liquid moderator and fuel elements immersed therein is disposed within a surrounding outer tank providing an annular space between the two tanks. This annular space is filled with liquid moderator which functions as a reflector to reflect neutrons back into the central reactor tank to increase the reproduction ratio. Means are provided for circulating and cooling the moderator material in both tanks and additional means are provided for controlling separately the volume of moderator in each tank, which latter means may be operated automatically by a neutron density monitoring device. The patent also shows an arrangement for controlling the chain reaction by injecting and varying an amount of poisoning material in the moderator used in the reflector portion of the reactor.

Human-system Interfaces for Automatic Systems  

SciTech Connect

Automation is ubiquitous in modern complex systems, and commercial nuclear- power plants are no exception. Automation is applied to a wide range of functions including monitoring and detection, situation assessment, response planning, and response implementation. Automation has become a 'team player' supporting personnel in nearly all aspects of system operation. In light of its increasing use and importance in new- and future-plants, guidance is needed to conduct safety reviews of the operator's interface with automation. The objective of this research was to develop such guidance. We first characterized the important HFE aspects of automation, including six dimensions: levels, functions, processes, modes, flexibility, and reliability. Next, we reviewed literature on the effects of all of these aspects of automation on human performance, and on the design of human-system interfaces (HSIs). Then, we used this technical basis established from the literature to identify general principles for human-automation interaction and to develop review guidelines. The guidelines consist of the following seven topics: automation displays, interaction and control, automation modes, automation levels, adaptive automation, error tolerance and failure management, and HSI integration. In addition, our study identified several topics for additional research.

[An improved, more reliable and more marketable version of the Automatic Metering System  

SciTech Connect

Texas Research Institute Austin, Inc. (TRI/Austin) was tasked by Letco International to evaluate its Automatic Metering System (AMS), a proportional controller for heat tracing cable. The original objectives were focused primarily on the reliability of the AMS controller. However, from the time of the original TRI/Austin proposal, the AMS device evolved beyond the prototype level into an established market product with sufficient operational experience and data that product reliability evaluation was not a significant test objective. The goals of this effort have been to determine the relative energy usage of the AMS proportional control compared to existing thermostatic control in a realistic freeze protection installation (low temperature test), to perform an accelerated life test for self limiting heat tracing cables to determine the service life impact of AMS control vs. thermostat control, and to perform a reliability analysis of the AMS device according to the 1986 edition of MIL-HDBK-217E [1] specifications. TRI/Austin designed and constructed a test set-up for conducting the low temperature test and the accelerated life test. A conceptual diagram of the test hardware is shown in Figure 1. The control computer was programmed to monitor and collect data from both tests in parallel, using the relay box and control circuitry fabricated at TRI/Austin. Test data and control commands were transmitted to and from the computer via standard parallel and serial interfaces. The AMS controller and relay box switched the power to the test cables, the commercial freezer, and the ALT chamber.

Remote Automatic Material On-Line Sensor  

DOE Green Energy (OSTI)

Low cost NMR sensor for measuring moisture content of forest products. The Department of Energy (DOE) Industries of the Future (IOF) program seeks development and implementation of technologies that make industry more efficient--in particular, more energy-efficient. Quantum Magnetics, Inc. (QM), a wholly-owned subsidiary of GE Security, received an award under the program to investigate roles for low-cost Nuclear Magnetic Resonance (NMR) technology in furtherance of these goals. Most NMR systems are designed for high-resolution spectroscopy applications. These systems use intense magnetic fields produced by superconducting magnets that drive price and operating cost to levels beyond industry tolerance. At low magnetic fields, achievable at low cost, one loses the ability to obtain spectroscopic information. However, measuring the time constants associated with the NMR signal, called NMR relaxometry, gives indications of chemical and physical states of interest to process control and optimization. It was the purpose of this effort to investigate the technical and economic feasibility of using such low-field, low-cost NMR to monitor parameters enabling greater process efficiencies. The primary target industry identified in the Cooperative Development Agreement was the wood industry, where the moisture content of wood is a key process parameter from the time the cut tree enters a mill until the time it is delivered as pieces of lumber. Extracting the moisture is energy consuming, and improvements in drying efficiency stand to reduce costs and emissions substantially. QM designed and developed a new, low-cost NMR instrument suitable for inspecting lumber up to 3 inches by 12 inches in cross section, and other materials of similar size. Low cost is achieved via an inexpensive, permanent magnet and low-cost NMR spectrometer electronics. Laboratory testing demonstrated that the NMR system is capable of accurate ({+-} 0.5%) measurements of the moisture content of wood for moisture ranging from 2% to over 140% (referenced to the wood's dry weight). Accuracy exceeded that offered by existing instrumentation when the moisture content was in excess of the fiber saturation point ({approx}20%). Accuracy was independent of the wood form: solid wood, wood chips or sawdust. The prototype NMR system was designed and built for incorporation and use in a beta test site. Beta testing is under way at the pilot plant operated by the Pulp and Paper Research Institute of Canada (PAPRICAN) in Vancouver, B.C. Other industries were also investigated. For example, laboratory testing demonstrated that low-field NMR is capable of measuring the hydrogen content of calcium oxide (quicklime). Hydrogen content measurement can be done both rapidly (on the order of 1 second) and nondestructively. Measurement of moisture in quicklime affects energy consumption in the steel industry. Further advances in system electronics, ongoing under DOD support, will enable yet more substantial system cost reductions over the prototype system, opening up a wider range of utility.

Nuggeteer: Automatic NuggetBased Evaluation using Descriptions and Judgements  

E-Print Network (OSTI)

The TREC Definition and Relationship questions are evaluated on the basis of information nuggets that may be contained in system responses. Human evaluators provide informal descriptions of each nugget, and judgements (assignments of nuggets to responses) for each response submitted by participants. While human evaluation is the most accurate way to compare systems, approximate automatic evaluation becomes critical during system development. We present Nuggeteer, a new automatic evaluation tool for nugget-based tasks. Like the first such tool, Pourpre, Nuggeteer uses words in common between candidate answer and answer key to approximate human judgements. Unlike Pourpre, but like human assessors, Nuggeteer creates a judgement for each candidatenugget pair, and can use existing judgements instead of guessing. This creates a more readily interpretable aggregate score, and allows developers to track individual nuggets through the variants of their system. Nuggeteer is quantitatively comparable in performance to Pourpre, and provides qualitatively better feedback to developers.

Automatic script identification from images using cluster-based templates  

SciTech Connect

We have developed a technique for automatically identifying the script used to generate a document that is stored electronically in bit image form. Our approach differs from previous work in that the distinctions among scripts are discovered by an automatic learning procedure, without any handson analysis. We first develop a set of representative symbols (templates) for each script in our database (Cyrillic, Roman, etc.). We do this by identifying all textual symbols in a set of training documents, scaling each symbol to a fixed size, clustering similar symbols, pruning minor clusters, and finding each cluster`s centroid. To identify a new document`s script, we identify and scale a subset of symbols from the document and compare them to the templates for each script. We choose the script whose templates provide the best match. Our current system distinguishes among the Armenian, Burmese, Chinese, Cyrillic, Ethiopic, Greek, Hebrew, Japanese, Korean, Roman, and Thai scripts with over 90% accuracy.

Mining Software Usage with the Automatic Library Tracking Database (ALTD)  

Science Conference Proceedings (OSTI)

Tracking software usage is important for HPC centers, computer vendors, code developers and funding agencies to provide more efficient and targeted software support, and to forecast needs and guide HPC software effort towards the Exascale era. However, accurately tracking software usage on HPC systems has been a challenging task. In this paper, we present a tool called Automatic Library Tracking Database (ALTD) that has been developed and put in production on several Cray systems. The ALTD infrastructure prototype automatically and transparently stores information about libraries linked into an application at compilation time and also the executables launched in a batch job. We will illustrate the usage of libraries, compilers and third party software applications on a system managed by the National Institute for Computational Sciences.

Automatic Speech Recognition using Pitch Information in Dynamic Bayesian Networks  

E-Print Network (OSTI)

The challenge of automatic speech recognition (ASR) increases when speaker variability is encountered. Being able to automatically use dierent acoustic models according to speaker type might help to increase the robustness of ASR. We present a system that attempts to do so by augmenting the standard acoustic observations with pitch information. This allows the system to use acoustic models more appropriate to speech with the given pitch. Furthermore, pitch information is more easily detected in noisy conditions; thus, it may be of use in robust speech recognition. Using dynamic Bayesian networks (DBNs) allows further renement of the system by eliminating unnecessary statistical dependencies and thus reducing the number of parameters. We show that when a system is trained on observed pitch data and performs recognition with missing pitch data, it can perform signicantly better than a system that uses acoustics information only.

Exploiting lower face symmetry in appearance-based automatic speechreading  

E-Print Network (OSTI)

Appearance-based visual speech feature extraction is being widely used in the automatic speechreading and audio-visual speech recognition literature. In its most common application, the discrete cosine transform (DCT) is utilized to compress the image of the speaker’s mouth region-of-interest (ROI), and the highest energy spatial frequency components are retained as visual features. Good generalization performance of the resulting system however requires robust ROI extraction and its consistent normalization, designed to compensate for speaker headpose and other data variations. In general, one expects that the ROI- if correctly normalized- will be nearly laterally symmetric, due to the approximate symmetry of human faces. We thus argue that forcing lateral ROI symmetry can be beneficial to automatic speechreading, providing a mechanism to compensate for small face and mouth tracking errors, which would otherwise result to incorrect ROI normalization. In this paper, we propose to achieve such ROI symmetry indirectly, by considering the spatial frequency domain and exploiting the DCT properties. In particular, we propose to remove the odd frequency DCT components from the selected visual feature vector. We experimentally demonstrate that, in general, this approach does not hurt speechreading performance, while it reduces computation, since it results to less DCT features. In addition, for the same number of features, as in traditional DCT coefficient selection, the method results in significant speechreading improvements. For the connected-digit automatic speechreading experiments considered, and for low feature dimensionalities, such can reach up to 12 % relative reduction in word error rate. 1.

Air control can improve field heater efficiency  

SciTech Connect

Independent field tests have demonstrated that the proper selection of primary and secondary air controls for wellhead gas dehydrators can reduce their burner fuel gas consumption by at least 30%. The tests were conducted by G.A. Baca and Associates Ltd., an engineering consulting firm located in Santa Fe, N.M. The new thermostat, venturi burner, and automatic secondary air control combination used in the tests were developed by Weatherford International as part of its Engineered Controls and Instruments (ECI) product line. The principle innovation of Weatherford's ECI burner/control combination is the Automatic Secondary Air Shutter, a device which limits the supply of secondary air surrounding the venturi burner. This air-flow control provides significant improvements in combustion efficiency compared to burners without such controls. Patents for the shutter and burner equipment are pending.

Coordinated train control and energy management control strategies  

DOE Green Energy (OSTI)

The Bay Area Rapid Transit (BART) system, in collaboration with Hughes Aircraft Company and Harmon Industries, as in the process of developing an Advanced Automatic Train Control (AATC) system to replace the current fixed-block automatic system. In the long run, the AATC system is expected to not only allow for safe short headway operation, but also to facilitate coordinated train control and energy management. This new system will employ spread spectrum radios, installed onboard trains, at wayside locations, and at control stations, to determine train locations and reliably transfer control information. Sandia National Laboratories has worked cooperatively with BART to develop a simulator of the train control and the power consumption of the AATC system. The authors are now in the process of developing enhanced train control algorithms to supplement the safety critical controller in order to smooth out train trajectories through coordinated control of multiple trains, and to reduce energy consumption and power infrastructure requirements. The control algorithms so far considered include (1) reducing peak power consumption to avoid voltage sags, especially during an outage or while clearing a backup, (2) rapid and smooth recovery from a backup, (3) avoiding oscillations due to train interference, (4) limiting needle peaks in power demand at substations to some specified level, (5) coasting, and (6) coordinating train movement, e.g., starts/stops and hills.

Automatic Continuous Commissioning of Measurement Instruments in Air Handling Units  

E-Print Network (OSTI)

This paper presents a robust strategy based on a condition-based adaptive statistical method for automatic commissioning of measurement instruments typically employed in air-handling units (AHU). The multivariate statistic method, principal component analysis (PCA), is adopted and modified to monitor the air handling process. Two PCA models are built corresponding to the heat balance and pressure-flow balance of the air-handling process. Sensor faults can be detected and isolated using the Q-statistic and the Q-contribution plot. The fault isolation ability against typical component faults is improved using knowledge-based analysis. A novel condition-based adaptive scheme is developed to update the PCA models with the operation conditions for continuous online application. A commissioning tool is developed to implement the strategy. Simulation tests and field tests in a building in Hong Kong were conducted to validate the automatic commissioning strategy for typical AHU. The integration of the tool with a building management system (BMS) and its application is demonstrated.

Automatic differentiation of advanced CFD codes for multidisciplinary design  

SciTech Connect

Automated multidisciplinary design of aircraft and other flight vehicles requires the optimization of complex performance objectives with respect to a number of design parameters and constraints. The effect of these independent design variables on the system performance criteria can be quantified in terms of sensitivity derivatives which must be calculated and propagated by the individual discipline simulation codes. Typical advanced CFD analysis codes do not provide such derivatives as part of a flow solution; these derivatives are very expensive to obtain by divided (finite) differences from perturbed solutions. It is shown here that sensitivity derivatives can be obtained accurately and efficiently using the ADIFOR source translator for automatic differentiation. In particular, it is demonstrated that the 3-D, thin-layer Navier-Stokes, multigrid flow solver called TLNS3D is amenable to automatic differentiation in the forward mode even with its implicit iterative solution algorithm and complex turbulence modeling. It is significant that using computational differentiation, consistent discrete nongeometric sensitivity derivatives have been obtained from an aerodynamic 3-D CFD code in a relatively short time, e.g. O(man-week) not O(man-year).

Automatic Age Estimation Based on Facial Aging Patterns  

E-Print Network (OSTI)

Abstract—While recognition of most facial variations, such as identity, expression, and gender, has been extensively studied, automatic age estimation has rarely been explored. In contrast to other facial variations, aging variation presents several unique characteristics which make age estimation a challenging task. This paper proposes an automatic age estimation method named AGES (AGing pattErn Subspace). The basic idea is to model the aging pattern, which is defined as the sequence of a particular individual’s face images sorted in time order, by constructing a representative subspace. The proper aging pattern for a previously unseen face image is determined by the projection in the subspace that can reconstruct the face image with minimum reconstruction error, while the position of the face image in that aging pattern will then indicate its age. In the experiments, AGES and its variants are compared with the limited existing age estimation methods (WAS and AAS) and some well-established classification methods (kNN, BP, C4.5, and SVM). Moreover, a comparison with human perception ability on age is conducted. It is interesting to note that the performance of AGES is not only significantly better than that of all the other algorithms, but also comparable to that of the human observers. Index Terms—Computer vision, pattern recognition, machine learning, face and gesture recognition, age estimation. 1

Automated manual transmission controller  

DOE Patents (OSTI)

A powertrain system for a hybrid vehicle. The hybrid vehicle includes a heat engine, such as a diesel engine, and an electric machine, which operates as both an electric motor and an alternator, to power the vehicle. The hybrid vehicle also includes a manual-style transmission configured to operate as an automatic transmission from the perspective of the driver. The engine and the electric machine drive an input shaft which in turn drives an output shaft of the transmission. In addition to driving the transmission, the electric machine regulates the speed of the input shaft in order to synchronize the input shaft during either an upshift or downshift of the transmission by either decreasing or increasing the speed of the input shaft. When decreasing the speed of the input shaft, the electric motor functions as an alternator to produce electrical energy which may be stored by a storage device. Operation of the transmission is controlled by a transmission controller which receives input signals and generates output signals to control shift and clutch motors to effect smooth launch, upshift shifts, and downshifts of the transmission, so that the transmission functions substantially as an automatic transmission from the perspective of the driver, while internally substantially functioning as a manual transmission.

Vertical axis wind turbine control strategy  

DOE Green Energy (OSTI)

Early expensive in automatic operation of the Sandia 17-m vertical axis research wind turbine (VAWT) has demonstrated the need for a systematic study of control algorithms. To this end, a computer model has been developed that uses actual wind time series and turbine performance data to calculate the power produced by the Sandia 17-m VAWT operating in automatic control. The model has been used to investigate the influence of starting algorithms on annual energy production. The results indicate that, depending on turbine and local wind characteristics, a bad choice of a control algorithm can significantly reduce overall energy production. The model can be used to select control algorithms and threshold parameters that maximize long-term energy production. An attempt has been made to generalize these results from local site and turbine characteristics to obtain general guidelines for control algorithm design.

REACTOR CONTROL DEVICE  

DOE Patents (OSTI)

A wholly mechanical compact control device is designed for automatically rendering the core of a fission reactor subcritical in response to core temperatures in excess of the design operating temperature limit. The control device comprises an expansible bellows interposed between the base of a channel in a reactor core and the inner end of a fuel cylinder therein which is normally resiliently urged inwardly. The bellows contains a working fluid which undergoes a liquid to vapor phase change at a temperature substantially equal to the design temperature limit. Hence, the bellows abruptiy expands at this limiting temperature to force the fuel cylinder outward and render the core subcritical. The control device is particularly applicable to aircraft propulsion reactor service. (AEC)

DOE Patents (OSTI)

Control systems for automatic positioning of an electric motor operated vapor valve are described which is operable under the severe conditions existing in apparatus for electro-magnetlcally separating isotopes. In general, the system includes a rotor for turning the valve comprising two colls mounted mutually perpendicular to each other and also perpendicular to the magnetic field of the isotope separating apparatus. The coils are furnished with both a-c and d- c current by assoclate control circuitry and a position control is provided for varying the ratlo of the a-c currents in the coils and at the same time, but in an inverse manner, the ratio between the d-c currents in the coils is varied. With the present system the magnitude of the motor torque is constant for all valves of the rotor orientatlon angle.

Programmable Logic Controllers  

E-Print Network (OSTI)

Programmable Logic Controllers (PLCs) drive the behavior of industrial control systems according to uploaded programs. It is now known that PLCs are vulnerable to the uploading of malicious code that can have severe physical consequences. What is not understood is whether an adversary with no knowledge of the PLC’s interface to the control system can execute a damaging, targeted, or stealthy attack against a control system using the PLC. In this paper, we present SABOT, a tool that automatically maps the control instructions in a PLC to an adversary-provided specification of the target control system’s behavior. This mapping recovers sufficient semantics of the PLC’s internal layout to instantiate arbitrary malicious controller code. This lowers the prerequisite knowledge needed to tailor an attack to a control system. SABOT uses an incremental model checking algorithm to map a few plant devices at a time, until a mapping is found for all adversary-specified devices. At this point, a malicious payload can be compiled and uploaded to the PLC. Our evaluation shows that SABOT correctly compiles payloads for all tested control systems when the adversary correctly specifies full system behavior, and for 4 out of 5 systems in most cases where there where unspecified features. Furthermore, SABOT completed all analyses in under 2 minutes.

Automatic O$(a)$ improvement for twisted-mass QCD  

E-Print Network (OSTI)

We present a condition for automatic O$(a)$ improvement in twisted mass lattice QCD, using symmetries of the Symanzik effective theory. If the continuum part of the Symanzik effective theory is invariant under a particular transformation, named $T_1$ in this report, scaling violations of all quantities invariant under $T_1$ transformation are even in the lattice spacing $a$. On the other hand, quantities non-invariant under $T_1$ vanish in the continuum limit with odd powers in $a$. We prove this statement even for the massive case without using the equation of motion. We also consider a few different criteria for the $T_1$ invariant condition in lattice theories and discuss ambiguities of the lattice condition for O$(a)$ improvement.

Automatic Acquisition of a Thesaurus of Interoperability Terms  

E-Print Network (OSTI)

Abstract: Enterprise Interoperability is the ability of different organizations to work together and exchange documents, data, services, best practices, etc. A preliminary step towards achieving this goal is the assessment of a common vocabulary of relevant domain concepts, a sort of initial, semi-formal, representation of shared domain knowledge. In this paper we describe an experiment, conducted within the INTEROP Network of Excellence (NoE), aimed at automatically extracting a thesaurus of interoperability terms from the web and a corpus of available documents. Statistical and text mining techniques have been used to extract a glossary of relevant terms and term definitions, as well as a preliminary taxonomic structure of the glossary. The result has been evaluated by a team of partners belonging to the NoE. Copyright © 2005 IFAC

A Geometric Approach For Fully Automatic Chromosome Segmentation  

E-Print Network (OSTI)

Chromosome segmentation is a fundamental task in human chromosome analysis. Most of previous methods for separation between touching chromosomes require human intervention. In this paper, a geometry based method is used for automatic chromosome segmentation. This method can be divided into two phases. In the first phase, chromosome clusters are detected using three geometric criteria and in the second phase chromosome clusters are separated using a proper cut line. However, most earlier methods do not work well with chromosome clusters that contain more than two chromosomes. Our method, on the other hand, has a high efficiency in separation of chromosome clusters in such scenarios. Another advantage of the proposed method is that it can easily apply to any type of images such as binary images. This is due to the fact that the proposed scheme uses the geometric features of chromosomes which are independent of the type of images. The performance of the proposed scheme is demonstrated on a database containing to...

Automatic detection and diagnosis of problems in drilling geothermal wells  

DOE Green Energy (OSTI)

Sandia National Laboratories and Tracor Applied Sciences have developed a proof-of-concept Expert System for the automatic detection and diagnosis of several important problems in geothermal drilling. The system is designed to detect loss of circulation, influx, loss of pump efficiency, and sensor problems. Data from flow sensors (including the rolling float meter), the pump stroke counter and other sensors are processed and examined for deviations from expected patterns. The deviations from expected patterns. The deviations are transformed into evidence for a Bayesian Network (a probabilistic reasoning tool), which estimates the probability of each fault. The results are displayed by a Graphical User Interface, which also allows the user to see data related to a specific fault. The prototype was tested on real data, and successfully detected and diagnosed faults.

Extending Metadata Definitions by Automatically Extracting and Organizing Glossary Definitions  

E-Print Network (OSTI)

Metadata descriptions of database contents are required to build and use systems that access and deliver data in response to user requests. When numerous heterogeneous databases are brought together in a single system, their various metadata formalizations must be homogenized and integrated in order to support the access planning and delivery system. This integration is a tedious process that requires human expertise and attention. In this paper we describe a method of speeding up the formalization and integration of new metadata. The method takes advantage of the fact that databases are often described in web pages containing natural language glossaries that define pertinent aspects of the data. Given a root URL, our method identifies likely glossaries, extracts and formalizes aspects of relevant concepts defined in them, and automatically integrates the new formalized metadata concepts into a large model of the domain and associated conceptualizations.

Automatic tuning of agent-based models using genetic algorithms  

E-Print Network (OSTI)

When developping multi-agent systems (MAS) or models in the context of agent-based simulation (ABS), the tuning of the model constitutes a crucial step of the design process. Indeed, agent-based models are generally characterized by lots of parameters, which together determine the global dynamics of the system. Moreover, small changes made to a single parameter sometimes lead to a radical modification of the dynamics of the whole system. The development and the parameter setting of an agent-based model can thus become long and tedious if we have no accurate, automatic and systematic strategy to explore this parameter space. That’s the development of such a strategy that we work on, suggesting the use of genetic algorithms. The idea is to capture in the fitness function the goal of the design process (efficiency for MAS that realize a given function, realism for agent-based models, etc.) and to make the model automatically evolve in that direction. However the use of genetic algorithms (GA) in the context of ABS raises specific difficulties that we develop in this article, explaining possible solutions and illustrating them on a simple and well-known model: the food-foraging by a colony of ants. We apply the method to a more complex example. We work on the simulation of the glycolysis and the phosphotranferase systems in Escherichia coli. In this work, we are interested in testing the hypothesis of hyperstructures, which are believed to improve the behavior of a cell. We try to determine under what conditions this may be true, and how these hyperstructures may function. 1

The National Ignition Facility (NIF) is a high power laser system capable of supporting high-energy-density experimentation as a user facility for the next 30 years. In order to maximize the facility availability, preventive maintenance enhancements are being introduced into the system. An example of such an enhancement is a camera-based health monitoring system, integrated into the automated alignment system, which provides an opportunity to monitor trends in measurements such as average beam intensity, size of the beam, and pixel saturation. The monitoring system will generate alerts based on observed trends in measurements to allow scheduled pro-active maintenance before routine off-normal detection stops system operations requiring unscheduled intervention.

B.: Tackling the internet glossary glut: Automatic extraction and evaluation of genus phrases  

E-Print Network (OSTI)

This paper addresses the problem of developing methods to be used in the identification and extraction of meaningful semantic components from large online glossaries. We present two sets of results. First, we report on the algorithm, ParseGloss, which was used to analyze definitions, and extract the main concept, or genus phrase. We ran the system on over 12,000 online glossary entries. Second, we present a method to evaluate our results, using human judgments on a collection of definitions from six different sources. This paper discusses our approach to the evaluation process, since the creation of a standard for evaluation is in itself a contribution to the field. The methods we have developed have required addressing the significant challenges of abstracting a single gold standard from multiple naive, human judgments on a highly subjective task. Once the method for creating the standard was developed, we then established the gold standard data. We report on our performance in running ParseGloss over this controlled collection of definitions. Our first set of results presents precision and recall on system performance. Our second results are presented in terms of techniques for determining agreement between human subjects. Success in the ParseGloss algorithm will contribute to the automatic creation of ontologies.

Automatic Construction of Anomaly Detectors from Graphical Models  

Science Conference Proceedings (OSTI)

Detection of rare or previously unseen attacks in cyber security presents a central challenge: how does one search for a sufficiently wide variety of types of anomalies and yet allow the process to scale to increasingly complex data? In particular, creating each anomaly detector manually and training each one separately presents untenable strains on both human and computer resources. In this paper we propose a systematic method for constructing a potentially very large number of complementary anomaly detectors from a single probabilistic model of the data. Only one model needs to be trained, but numerous detectors can then be implemented. This approach promises to scale better than manual methods to the complex heterogeneity of real-life data. As an example, we develop a Latent Dirichlet Allocation probability model of TCP connections entering Oak Ridge National Laboratory. We show that several detectors can be automatically constructed from the model and will provide anomaly detection at flow, sub-flow, and host (both server and client) levels. This demonstrates how the fundamental connection between anomaly detection and probabilistic modeling can be exploited to develop more robust operational solutions.

Automatic Generation of Tcl Bindings for C and C++ Libraries  

E-Print Network (OSTI)

In the past few years Tcl has found widespread interest as a extensible scripting language. Numerous Tcl interfaces for a variety of C libraries have been created. While most of these language bindings have been created by hand, others have made use of dedicated code generators designed for the specific library. In this paper we present a tool for the automatic generation of Tcl language bindings for arbitrary C libraries. Moreover, the mapping of C++ class hierarchies to [incr Tcl] classes will be described. 1 Introduction 1.1 Prior Work One of the reasons for the recent success of Tcl is its powerful API to C and C++, which allows the extension of the core language with commands implemented as C functions. This facility has been used to create a variety of language bindings for C libraries, ranging from different 3D graphics libraries (iris gl, OpenGL, vogle, sipp) to several X widget sets, for example Wafe and tclMotif. While most of this work has been done manually, other bind...

Development report: automatic system test and calibration (ASTAC) equipment  

DOE Green Energy (OSTI)

The Automatic System Test and Calibration (ASTAC) Equipment has been developed by Paragon Pacific, Inc. to be used in conjunction with the NASA Lewis Research Center Wind Energy System Time-Domain (WEST) Analyzer. ASTAC is used to monitor the performance of the WEST Analyzer and to identify component malfunctions which may occur from time to time within WEST. The heart of the ASTAC system is a microcomputer which is used to input prescribed test signals into all WEST subsystems via a hybrid interface unit, and to process WEST output responses to these test signals. Measured responses are compared to theoretical levels calculated off-line using specialized ASTAC software. This report describes the microcomputer, the interface unit and the software packages which in total comprise the ASTAC system. Examples of ASTAC test results obtained on the WEST Analyzer are presented and described in detail. In addition, a section has been included which briefly describes the methods by which the microcomputer and interface unit can be maintained.

Analysing solar-like oscillations with an automatic pipeline  

E-Print Network (OSTI)

Kepler mission will provide a huge amount of asteroseismic data during the next few years, among which hundreds of solar-like stars will be targeted. The amount of stars and their observation length represent a step forward in the comprehension of the stellar evolution that has already been initiated by CoRoT and MOST missions. Up to now, the slow cadence of observed targets allowed an individual and personalized analysis of each star. During the survey phase of Kepler, this will be impossible. This is the reason why, within the AsteroFLAG team, we have been developing automatic pipelines for the Kepler solar-like oscillation stars. Our code starts by finding the frequency-range where p-mode power is present and, after fitting the background, it looks for the mode amplitudes as well as the central frequency of the p-mode hump. A good estimation of the large separation can thus be inferred in this region. If the signal to noise is high enough, the code obtains the characteristics of the p modes by doing a glob...

Factors for conversion between human and automatic read-outs of CDMAM images  

SciTech Connect

Purpose: According to the European protocol for the quality control of the physical and technical aspects of mammography screening (EPQCM) image quality of digital mammography devices has to be assessed using human evaluation of the CDMAM contrast-detail phantom. This is accomplished by the determination of threshold thicknesses of gold disks with different diameters (0.08-2 mm) and revealed to be very time consuming. Therefore a software solution based on a nonprewhitening matched filter (NPW) model was developed at University of Nijmegen. Factors for the conversion from automatic to human readouts have been determined by Young et al.[Proc. SPIE 614206, 1-13 (2006) and Proc. SPIE 6913, 69131C1 (2008)] using a huge amount of data of both human and automatic readouts. These factors depend on the observer groups and are purely phenomenological. The authors present an alternative approach to determine the factors by using the Rose observer model. Methods: Their method uses the Rose theory which gives a relationship between threshold contrast, diameter of the object and number of incident photons. To estimate the conversion factors for the five diameters from 0.2 to 0.5 mm they exposed with five different current-time products which resulted in 25 equations with five unknowns. Results: The theoretical conversion factors (in dependence of the diameters) amounted to be 1.61 {+-} 0.02 (0.2 mm diameter), 1.67 {+-} 0.02 (0.25 mm), 1.85 {+-} 0.02 (0.31 mm), 2.09 {+-} 0.02 (0.4 mm), and 2.28 {+-} 0.02 (0.5 mm). The corresponding phenomenological factors found in literature are 1.74 (0.2 mm), 1.78 (0.25 mm), 1.83 (0.31 mm), 1.88 (0.4 mm), and 1.93 (0.5 mm). Conclusions: They transferred the problem of determining the factors to a well known observer model which has been examined for many years and is also well established. This method reveals to be reproduceable and produces factors comparable to the phenomenological ones.

OpenAD/F: Automatic Differentiation of Fortran Codes OpenAD/F: Automatic Differentiation of Fortran Codes OpenAD/F: Automatic Differentiation of Fortran Codes The OpenAD/F project seeks to develop a modular, open-source tool for the automatic generation of adjoint code from Fortran 95 source code. Discrete adjoint computations are used for sensitivity analysis and to provide the gradients used in geophysical state estimation. Because derivatives are needed with respect to millions or billions of independent variables, finite different approximations are impractical: a gradient computation that would take minutes or hours using an adjoint computation would take months or years using finite differences.

Automatic ID heat load generation in ANSYS code  

SciTech Connect

Detailed power density profiles are critical in the execution of a thermal analysis using a finite element (FE) code such as ANSYS. Unfortunately, as yet there is no easy way to directly input the precise power profiles into ANSYS. A straight-forward way to do this is to hand-calculate the power of each node or element and then type the data into the code. Every time a change is made to the FE model, the data must be recalculated and reentered. One way to solve this problem is to generate a set of discrete data, using another code such as PHOTON2, and curve-fit the data. Using curve-fitted formulae has several disadvantages. It is time consuming because of the need to run a second code for generation of the data, curve-fitting, and doing the data check, etc. Additionally, because there is no generality for different beamlines or different parameters, the above work must be repeated for each case. And, errors in the power profiles due to curve-fitting result in errors in the analysis. To solve the problem once and for all and with the capability to apply to any insertion device (ID), a program for ED power profile was written in ANSYS Parametric Design Language (APDL). This program is implemented as an ANSYS command with input parameters of peak magnetic field, deflection parameter, length of ID, and distance from the source. Once the command is issued, all the heat load will be automatically generated by the code.

Generating Remote Control Interfaces for Complex Appliances  

E-Print Network (OSTI)

The personal universal controller (PUC) is an approach for improving the interfaces to complex appliances by introducing an intermediary graphical or speech interface. A PUC engages in two-way communication with everyday appliances, first downloading a specification of the appliance's functions, and then automatically creating an interface for controlling that appliance. The specification of each appliance includes a high-level description of every function, a hierarchical grouping of those functions, and dependency information, which relates the availability of each function to the appliance's state. Dependency information makes it easier for designers to create specifications and helps the automatic interface generators produce a higher quality result. We describe the architecture that supports the PUC, and the interface generators that use our specification language to build high-quality graphical and speech interfaces.

Automated manual transmission clutch controller  

DOE Patents (OSTI)

A powertrain system for a hybrid vehicle. The hybrid vehicle includes a heat engine, such as a diesel engine, and an electric machine, which operates as both an electric motor and an alternator, to power the vehicle. The hybrid vehicle also includes a manual-style transmission configured to operate as an automatic transmission from the perspective of the driver. The engine and the electric machine drive an input shaft which in turn drives an output shaft of the transmission. In addition to driving the transmission, the electric machine regulates the speed of the input shaft in order to synchronize the input shaft during either an upshift or downshift of the transmission by either decreasing or increasing the speed of the input shaft. When decreasing the speed of the input shaft, the electric motor functions as an alternator to produce electrical energy which may be stored by a storage device. Operation of the transmission is controlled by a transmission controller which receives input signals and generates output signals to control shift and clutch motors to effect smooth launch, upshift shifts, and downshifts of the transmission, so that the transmission functions substantially as an automatic transmission from the perspective of the driver, while internally substantially functioning as a manual transmission.

DIII-D cryogenics control system status  

SciTech Connect

The DIII-D cryogenics system provides liquid helium for various auxiliary systems at the DIII-D tokamak facility. The system described here executes control and supervision of the cryogenics plant and associated load systems which include four neutral beam injectors, superconducting magnets, and an in-vessel tokamak cryocondensation pump. The recent addition of this divertor cryopump represented a major increase in the scope of the control system and greater need for reliable and automatic operation. The pump must be precooled, cooled and regenerated in a relatively short period of time under automatic control. Since the pump is located in the tokamak primary vacuum, coordination with the machine vacuum control system and consideration for the requirements of physics operations and vessel wall conditioning are required. A programmable logic controller is the central element in the cryogenics control system and exercises direct or supervisory control over the liquefier, gas management and loads. In the time since the control system was built during 1989, additions and improvements have been made to simplify operation and support upgrades. Cryogenics system capacity has been upgraded by the purchase of a new 150 {ell}/hr helium liquefier, a second 400 hp helium compressor and additional gas storage. The new liquefier incorporates a controller of its own which exchanges information with the cryogenics control system. This independent controller relieved the main system of liquefier process control tasks but necessitates much finer control of the system high and low pressures. The control system upgrades and automation are discussed with emphasis on the divertor cryocondensation pump control.

The Automatic Real-Time GRB Pipeline of the 2-m Liverpool Telescope  

E-Print Network (OSTI)

The 2-m Liverpool Telescope (LT), owned by Liverpool John Moores University, is located in La Palma (Canary Islands) and operates in fully robotic mode. In 2005, the LT began conducting an automatic GRB follow-up program. On receiving an automatic GRB alert from a Gamma-Ray Observatory (Swift, INTEGRAL, HETE-II, IPN) the LT initiates a special override mode that conducts follow-up observations within 2-3 min of the GRB onset. This follow-up procedure begins with an initial sequence of short (10-s) exposures acquired through an r' band filter. These images are reduced, analyzed and interpreted automatically using pipeline software developed by our team called "LT-TRAP" (Liverpool Telescope Transient Rapid Analysis Pipeline); the automatic detection and successful identification of an unknown and potentially fading optical transient triggers a subsequent multi-color imaging sequence. In the case of a candidate brighter than r'=15, either a polarimetric (from 2006) or a spectroscopic observation (from 2007) will be triggered on the LT. If no candidate is identified, the telescope continues to obtain z', r' and i' band imaging with increasingly longer exposure times. Here we present a detailed description of the LT-TRAP and briefly discuss the illustrative case of the afterglow of GRB 050502a, whose automatic identification by the LT just 3 min after the GRB, led to the acquisition of the first early-time (< 1 hr) multi-color light curve of a GRB afterglow.

Intermediate leak protection/automatic shutdown for B and W helical coil steam generator  

SciTech Connect

The report summarizes a follow-on study to the multi-tiered Intermediate Leak/Automatic Shutdown System report. It makes the automatic shutdown system specific to the Babcock and Wilcox (B and W) helical coil steam generator and to the Large Development LMFBR Plant. Threshold leak criteria specific to this steam generator design are developed, and performance predictions are presented for a multi-tier intermediate leak, automatic shutdown system applied to this unit. Preliminary performance predictions for application to the helical coil steam generator were given in the referenced report; for the most part, these predictions have been confirmed. The importance of including a cover gas hydrogen meter in this unit is demonstrated by calculation of a response time one-fifth that of an in-sodium meter at hot standby and refueling conditions.

Automatic feature detection and identification in digital point-ordered signals  

DOE Patents (OSTI)

A computer-based automated method to detect and identify features in digital point-ordered signals. The method is used for processing of non-destructive test signals, such as eddy current signals obtained from calibration standards. The signals are first automatically processed to remove noise and to determine a baseline. Next, features are detected in the signals using mathematical morphology filters. Finally, verification of the features is made using an expert system of pattern recognition methods and geometric criteria. The method has the advantage that standard features can be located without prior knowledge of the number or sequence of the features. Further advantages are that standard features can be differentiated from irrelevant signals features such as noise, and detected features are automatically verified by parameters extracted from the signals. The method proceeds fully automatically without initial operator set-up and without subjective operator feature judgment.

Semi-automatic system for ultrasonic measurement of texture  

DOE Patents (OSTI)

A means and method are disclosed for ultrasonic measurement of texture nondestructively and efficiently. Texture characteristics are derived by transmitting ultrasound energy into the material, measuring the time it takes to be received by ultrasound receiving means, and calculating velocity of the ultrasound energy from the timed measurements. Textured characteristics can then be derived from the velocity calculations. One or more sets of ultrasound transmitters and receivers are utilized to derive velocity measurements in different angular orientations through the material and in different ultrasound modes. An ultrasound transmitter is utilized to direct ultrasound energy to the material and one or more ultrasound receivers are utilized to receive the same. The receivers are at a predetermined fixed distance from the transmitter. A control means is utilized to control transmission of the ultrasound, and a processing means derives timing, calculation of velocity and derivation of texture characteristics. 5 figures.

Automatic computation for optimum height planning of apartment buildings to improve solar access  

SciTech Connect

The objective of this study is to suggest a mathematical model and an optimal algorithm for determining the height of apartment buildings to satisfy the solar rights of survey buildings or survey housing units. The objective is also to develop an automatic computation model for the optimum height of apartment buildings and then to clarify the performance and expected effects. To accomplish the objective of this study, the following procedures were followed: (1) The necessity of the height planning of obstruction buildings to satisfy the solar rights of survey buildings or survey housing units is demonstrated by analyzing through a literature review the recent trend of disputes related to solar rights and to examining the social requirements in terms of solar rights. In addition, the necessity of the automatic computation system for height planning of apartment buildings is demonstrated and a suitable analysis method for this system is chosen by investigating the characteristics of analysis methods for solar rights assessment. (2) A case study on the process of height planning of apartment buildings will be briefly described and the problems occurring in this process will then be examined carefully. (3) To develop an automatic computation model for height planning of apartment buildings, geometrical elements forming apartment buildings are defined by analyzing the geometrical characteristics of apartment buildings. In addition, design factors and regulations required in height planning of apartment buildings are investigated. Based on this knowledge, the methodology and mathematical algorithm to adjust the height of apartment buildings by automatic computation are suggested and probable problems and the ways to resolve these problems are discussed. Finally, the methodology and algorithm for the optimization are suggested. (4) Based on the suggested methodology and mathematical algorithm, the automatic computation model for optimum height of apartment buildings is developed and the developed system is verified through the application of some cases. The effects of the suggested model are then demonstrated quantitatively and qualitatively. (author)

Advanced mobile networking, sensing, and controls.  

SciTech Connect

This report describes an integrated approach for designing communication, sensing, and control systems for mobile distributed systems. Graph theoretic methods are used to analyze the input/output reachability and structural controllability and observability of a decentralized system. Embedded in each network node, this analysis will automatically reconfigure an ad hoc communication network for the sensing and control task at hand. The graph analysis can also be used to create the optimal communication flow control based upon the spatial distribution of the network nodes. Edge coloring algorithms tell us that the minimum number of time slots in a planar network is equal to either the maximum number of adjacent nodes (or degree) of the undirected graph plus some small number. Therefore, the more spread out that the nodes are, the fewer number of time slots are needed for communication, and the smaller the latency between nodes. In a coupled system, this results in a more responsive sensor network and control system. Network protocols are developed to propagate this information, and distributed algorithms are developed to automatically adjust the number of time slots available for communication. These protocols and algorithms must be extremely efficient and only updated as network nodes move. In addition, queuing theory is used to analyze the delay characteristics of Carrier Sense Multiple Access (CSMA) networks. This report documents the analysis, simulation, and implementation of these algorithms performed under this Laboratory Directed Research and Development (LDRD) effort.

Guidance for Human-system Interfaces to Automatic Systems  

Science Conference Proceedings (OSTI)

Automation is ubiquitous in modern complex systems, and commercial nuclear- power plants are no exception. Automation is applied to a wide range of functions, including monitoring and detection, situation assessment, response planning, and response implementation. Automation has become a 'team player' supporting personnel in nearly all aspects of system operation. In light of its increasing use and importance in new- and future-plants, guidance is needed to conduct safety reviews of the operator's interface with automation. The objective of this research was to develop such guidance. We first characterized the important HFE aspects of automation, including six dimensions: Levels, functions, processes, modes, flexibility, and reliability. Next, we reviewed literature on the effects of all of these aspects of automation on human performance, and on the design of human-system interfaces (HSIs). Then, we used this technical basis established from the literature to identify general principles for human-automation interaction and to develop review guidelines. The guidelines consist of the following seven topics: Automation displays, interaction and control, automation modes, automation levels, adaptive automation, error tolerance and failure management, and HSI integration.

Autonomous, teleoperated, and shared control of robot systems  

Science Conference Proceedings (OSTI)

This paper illustrates how different modes of operation such as bilateral teleoperation, autonomous control, and shared control can be described and implemented using combinations of modules in the SMART robot control architecture. Telerobotics modes are characterized by different ``grids`` of SMART icons, where each icon represents a portion of run-time code that implements a passive control law. By placing strict requirements on the module`s input-output behavior and using scattering theory to develop a passive sampling technique, a flexible, expandable telerobot architecture is achieved. An automatic code generation tool for generating SMART systems is also described.

Semi-Automatic Distribution Pattern Modeling of Web Service Compositions using Semantics  

E-Print Network (OSTI)

Enterprise systems are frequently built by combining a number of discrete Web services together, a process termed composition. There are a number of architectural configurations or distribution patterns, which express how a composed system is to be deployed. Previously, we presented a Model Driven Architecture using UML 2.0, which took existing service interfaces as its input and generated an executable Web service composition, guided by a distribution pattern model. In this paper, we propose using Web service semantic descriptions in addition to Web service interfaces, to assist in the semi-automatic generation of the distribution pattern model. Web services described using semantic languages, such as OWL-S, can be automatically assessed for compatibility and their input and output messages can be mapped to each other. 1.

Identifying Software Usage at HPC Centers with the Automatic Library Tracking Database  

SciTech Connect

A library tracking database has been developed to monitor software/library usage. This Automatic Library Tracking Database (ALTD) automatically and transparently stores, into a database, information about the libraries linked into an application at compilation time and also the executables launched in a batch job. Information gathered into the database can then be mined to provide reports. Analyzing the results from the data collected will help to identify, for example, the most frequently used and the least used libraries and codes, and those users that are using deprecated libraries or applications. We will illustrate the usage of libraries and executables on the Cray XT platforms hosted at the National Institute for Computational Sciences and the Oak Ridge Leadership Computing Facility (both located at Oak Ridge National Laboratory).

Using a MaxEnt Classifier for the Automatic Content Scoring of Free-Text Responses  

SciTech Connect

Criticisms against multiple-choice item assessments in the USA have prompted researchers and organizations to move towards constructed-response (free-text) items. Constructed-response (CR) items pose many challenges to the education community - one of which is that they are expensive to score by humans. At the same time, there has been widespread movement towards computer-based assessment and hence, assessment organizations are competing to develop automatic content scoring engines for such items types - which we view as a textual entailment task. This paper describes how MaxEnt Modeling is used to help solve the task. MaxEnt has been used in many natural language tasks but this is the first application of the MaxEnt approach to textual entailment and automatic content scoring.

CONTROL AND FAULT DETECTOR CIRCUIT  

DOE Patents (OSTI)

A power control and fault detectcr circuit for a radiofrequency system is described. The operation of the circuit controls the power output of a radio- frequency power supply to automatically start the flow of energizing power to the radio-frequency power supply and to gradually increase the power to a predetermined level which is below the point where destruction occurs upon the happening of a fault. If the radio-frequency power supply output fails to increase during such period, the control does not further increase the power. On the other hand, if the output of the radio-frequency power supply properly increases, then the control continues to increase the power to a maximum value. After the maximumn value of radio-frequency output has been achieved. the control is responsive to a ''fault,'' such as a short circuit in the radio-frequency system being driven, so that the flow of power is interrupted for an interval before the cycle is repeated.

Integrating preconcentrator heat controller  

DOE Patents (OSTI)

A method and apparatus for controlling the electric resistance heating of a metallic chemical preconcentrator screen, for example, used in portable trace explosives detectors. The length of the heating time-period is automatically adjusted to compensate for any changes in the voltage driving the heating current across the screen, for example, due to gradual discharge or aging of a battery. The total deposited energy in the screen is proportional to the integral over time of the square of the voltage drop across the screen. Since the net temperature rise, .DELTA.T.sub.s, of the screen, from beginning to end of the heating pulse, is proportional to the total amount of heat energy deposited in the screen during the heating pulse, then this integral can be calculated in real-time and used to terminate the heating current when a pre-set target value has been reached; thereby providing a consistent and reliable screen temperature rise, .DELTA.T.sub.s, from pulse-to-pulse.

LMR design to facilitate control  

SciTech Connect

Recent testing in the Experimental Breeder Reactor-II (EBR-II) has demonstrated the potential for passively accomplishing basic reactor safety functions. Tests have shown that reactor feedbacks can safely shut down the reactor for loss of flow and loss of heat sink accidents and that natural convection can subsequently cool the reactor without aid of active components. Analysis has indicated that passive safety for the transient overpower and loss of coolant events can also be achieved for a larger LMR with metal fuel. The analyses and experiments suggest that there will be both special constraints and opportunities for the design of automatic control and protection systems for inherently safe reactor plants. The constraints are generally a restriction on the control band'' of active components so that they cannot override the reactivity feedbacks, or natural convective heads which otherwise inherently carry out the safety functions. The opportunities for improvement of reactor controls are generally in two areas. First the complexity of safety systems (which evolves from the philosophy of safety reliability through redundancy, diversity and independence) can be reduced. The reliability and diverse nature of passive shutdown, convective heat removal and hydrostatic mitigation of leaks in the primary boundary allow considerable simplification or deletion of active control and protection system, while at the same time improving reliability of the safety functions. 10 refs., 4 figs.

Automated manual transmission mode selection controller  

DOE Patents (OSTI)

A powertrain system for a hybrid vehicle. The hybrid vehicle includes a heat engine, such as a diesel engine, and an electric machine, which operates as both an electric motor and an alternator, to power the vehicle. The hybrid vehicle also includes a manual-style transmission configured to operate as an automatic transmission from the perspective of the driver. The engine and the electric machine drive an input shaft which in turn drives an output shaft of the transmission. In addition to driving the transmission, the electric machine regulates the speed of the input shaft in order to synchronize the input shaft during either an upshift or downshift of the transmission by either decreasing or increasing the speed of the input shaft. When decreasing the speed of the input shaft, the electric motor functions as an alternator to produce electrical energy which may be stored by a storage device. Operation of the transmission is controlled by a transmission controller which receives input signals and generates output signals to control shift and clutch motors to effect smooth launch, upshift shifts, and downshifts of the transmission, so that the transmission functions substantially as an automatic transmission from the perspective of the driver, while internally substantially functioning as a manual transmission.

Servo control booster system for minimizing following error  

DOE Patents (OSTI)

A closed-loop feedback-controlled servo system is disclosed which reduces command-to-response error to the system's position feedback resolution least increment, .DELTA.S.sub.R, on a continuous real-time basis for all operating speeds. The servo system employs a second position feedback control loop on a by exception basis, when the command-to-response error .gtoreq..DELTA.S.sub.R, to produce precise position correction signals. When the command-to-response error is less than .DELTA.S.sub.R, control automatically reverts to conventional control means as the second position feedback control loop is disconnected, becoming transparent to conventional servo control means. By operating the second unique position feedback control loop used herein at the appropriate clocking rate, command-to-response error may be reduced to the position feedback resolution least increment. The present system may be utilized in combination with a tachometer loop for increased stability.

MDP Optimal Control under Temporal Logic Constraints  

E-Print Network (OSTI)

In this paper, we develop a method to automatically generate a control policy for a dynamical system modeled as a Markov Decision Process (MDP). The control specification is given as a Linear Temporal Logic (LTL) formula over a set of propositions defined on the states of the MDP. We synthesize a control policy such that the MDP satisfies the given specification almost surely, if such a policy exists. In addition, we designate an "optimizing proposition" to be repeatedly satisfied, and we formulate a novel optimization criterion in terms of minimizing the expected cost in between satisfactions of this proposition. We propose a sufficient condition for a policy to be optimal, and develop a dynamic programming algorithm that synthesizes a policy that is optimal under some conditions, and sub-optimal otherwise. This problem is motivated by robotic applications requiring persistent tasks, such as environmental monitoring or data gathering, to be performed.

The Liverpool Telescope Automatic Pipeline for Real-time GRB Afterglow Detection  

E-Print Network (OSTI)

The 2-m robotic Liverpool Telescope (LT) is ideally suited to the rapid follow-up of unpredictable and transient events such as GRBs. Our GRB follow-up strategy is designed to identify optical/IR counterparts in real time; it involves the automatic triggering of initial observations, on receipt of an alert from Gamma Ray Observatories HETE-2, INTEGRAL and Swift, followed by automated data reduction, analysis, OT identification and subsequent observing mode choice. The lack of human intervention in this process requires robustness at all stages of the procedure. Here we describe the telescope, its instrumentation and GRB pipeline.

Automatic generation of stop word lists for information retrieval and analysis  

DOE Patents (OSTI)

Methods and systems for automatically generating lists of stop words for information retrieval and analysis. Generation of the stop words can include providing a corpus of documents and a plurality of keywords. From the corpus of documents, a term list of all terms is constructed and both a keyword adjacency frequency and a keyword frequency are determined. If a ratio of the keyword adjacency frequency to the keyword frequency for a particular term on the term list is less than a predetermined value, then that term is excluded from the term list. The resulting term list is truncated based on predetermined criteria to form a stop word list.

Application of automatic differentiation for the simulation of nonisothermal, multiphase flow in geothermal reservoirs  

DOE Green Energy (OSTI)

Simulation of nonisothermal, multiphase flow through fractured geothermal reservoirs involves the solution of a system of strongly nonlinear algebraic equations. The Newton-Raphson method used to solve such a nonlinear system of equations requires the evaluation of a Jacobian matrix. In this paper we discuss automatic differentiation (AD) as a method for analytically computing the Jacobian matrix of derivatives. Robustness and efficiency of the AD-generated derivative codes are compared with a conventional derivative computation approach based on first-order finite differences.

Automatic Calibration of a Building Energy Simulation Model Using a Global Optimization Program

A simulation model used to analyze the energy performance of an existing building should be calibrated to measured consumption data from the building so the simulation output closely follows the measured time series energy consumption data and shows the same temperature dependence. This paper has used optimization software to show that a simple simulation program which is a coding of the ASHRAE 'Simplified Energy Analysis Procedure' can be automatically calibrated to “measured” data. The “measured data” used in this case study was simulation data to which a small amount of white noise had been added.

Knowledge representations for the automatic generation of numerical simulators for PDEs  

Science Conference Proceedings (OSTI)

In this paper we describe an automatic programming (AP) system which generates numerical discretization schemes for partial differential equation (PDE) problems. This system is based on the observation that a wide variety of discretization schemes can be mechanically produced by computing surface integrals of spacetime currents. However, surface integration is difficult to carry out using conventional vector calculus. For this reason, the system is structured to include the differential geometry formalisms which make high dimensional surface integration simple. The differential geometry formalisms have also simplified the representation of continuous physics problems and increased the domain of applicability of the system. 10 refs., 1 fig., 3 tabs.

Abstract — We propose a new method for extrinsic calibration of a line-scan LIDAR with a perspective projection camera. Our method is a closed-form, minimal solution to the problem. The solution is a symbolic template found via variable elimination and the multi-polynomial Macaulay resultant. It does not require initialization, and can be used in an automatic calibration setting when paired with RANSAC and least-squares refinement. We show the efficacy of our approach through a set of simulations and a real calibration. I.

Direct Digital Control- A Tool for Energy Management of HVAC Systems  

E-Print Network (OSTI)

Direct digital control (DDC) applied to heating, ventilating, and air-conditioning (HVAC) systems corrects many of the deficiencies of conventional automatic temperature control systems. By applying new control sequences, DDC optimizes HVAC energy use. DDC can reduce HVAC operation and maintenance time and provide the environmental conditions needed to maximize production. DDC technology uses standalone, microprocessor based controllers. Controllers directly sense and process control variables (e.g. temperature, pressure) and provide a control signal to an actuator. Personal computers provide remote or local access to the digital controllers and give HVAC mechanics, energy managers, and facility engineers capabilities that conventional control systems do not offer. This paper discusses the most common deficiencies of conventionally controlled HVAC systems, advantages of DOC systems, and a case study retrofit from pneumatic control to digital control.

Automated Voltage Control in LHCb  

E-Print Network (OSTI)

LHCb is one of the 4 LHC experiments. In order to ensure the safety of the detector and to maximize efficiency, LHCb needs to coordinate its own operations, in particular the voltage configuration of the different subdetectors, according to the accelerator status. A control software has been developed for this purpose, based on the Finite State Machine toolkit and the SCADA system used for control throughout LHCb (and the other LHC experiments). This software permits to efficiently drive both the Low Voltage (LV) and High Voltage (HV) systems of the 10 different sub-detectors that constitute LHCb, setting each sub-system to the required voltage (easily configurable at run-time) based on the accelerator state. The control software is also responsible for monitoring the state of the Sub-detector voltages and adding it to the event data in the form of status-bits. Safe and yet flexible operation of the LHCb detector has been obtained and automatic actions, triggered by the state changes of the ...

Institutional Controls  

NLE Websites -- All DOE Office Websites (Extended Search)

Institutional Controls Institutional Controls Many major Federal laws (e.g., Atomic Energy Act (AEA), Resource Conservation Recovery Act (RCRA), Comprehensive Environmental Response, Compensation and Liability Act (CERCLA)), Executive Orders, regulations and various other drivers influence the use of institutional controls at DOE sites. Some drivers directly authorize or require the use of institutional controls, while others do not. DOE also uses institutional controls when no specific statutory requirement exists to supplement active remediation, pollution control, public and resource protection, and physical security, or to bolster the integrity of engineered remedies. DOE and its predecessor agencies have conducted activities for over 50 years, using land ownership and access control, environmental monitoring and surveillance, and other tools to support protection efforts at operational and inactive facilities, including radioactive waste burial grounds.

Correctness Analysis Of An Embedded Controller  

E-Print Network (OSTI)

In this paper we report on the use of a new method for quality assurance of safety-critical software in aerospace applications. The power and thermal control unit (PTC) of the X-ray satellite "Abrixas", developed by OHB System GmbH, Bremen, was analysed with this new formal method. On the basis of formal specifications we automatically generated and executed test sequences for the reactive behaviour of the controller. We checked the full functionality of the PTC, including real-time and hybrid properties, user interaction, stress- and long-term behaviour, and fault tolerance. Our tool VVT-RT generated an extensive coverage of test sequences for these properties. The tests were then automatically performed and evaluated, using the original hardware in a simulation environment. Due to the universality of VVTRT, only little effort was necessary to set up the interfaces. Thus, even though we achieved a higher test coverage, the overall costs of the validation were much lower than with comp...

Experience with automatic, dynamic load balancing and adaptive finite element computation  

SciTech Connect

Distributed memory, Massively Parallel (MP), MIMD technology has enabled the development of applications requiring computational resources previously unobtainable. Structural mechanics and fluid dynamics applications, for example, are often solved by finite element methods (FEMs) requiring, millions of degrees of freedom to accurately simulate physical phenomenon. Adaptive methods, which automatically refine or coarsen meshes and vary the order of accuracy of the numerical solution, offer greater robustness and computational efficiency than traditional FEMs by reducing the amount of computation required away from physical structures such as shock waves and boundary layers. On MP computers, FEMs frequently result in distributed processor load imbalances. To overcome load imbalance, many MP FEMs use static load balancing as a preprocessor to the finite element calculation. Adaptive methods complicate the load imbalance problem since the work per element is not uniform across the solution domain and changes as the computation proceeds. Therefore, dynamic load balancing is required to maintain global load balance. We describe a dynamic, fine-grained, element-based data migration system that maintains global load balance and is effective in the presence of changing work loads. Global load balance is achieved by overlapping neighborhoods of processors, where each neighborhood performs local load balancing. The method utilizes an automatic element management system library to which a programmer integrates the application`s computational description. The library`s flexibility supports a large class of finite element and finite difference based applications.

Automatic Transformation of MPI Programs to Asynchronous, Graph-Driven Form  

SciTech Connect

The goals of this project are to develop new, scalable, high-fidelity algorithms for atomic-level simulations and program transformations that automatically restructure existing applications, enabling them to scale forward to Petascale systems and beyond. The techniques enable legacy MPI application code to exploit greater parallelism though increased latency hiding and improved workload assignment. The techniques were successfully demonstrated on high-end scalable systems located at DOE laboratories. Besides the automatic MPI program transformations efforts, the project also developed several new scalable algorithms for ab-initio molecular dynamics, including new massively parallel algorithms for hybrid DFT and new parallel in time algorithms for molecular dynamics and ab-initio molecular dynamics. These algorithms were shown to scale to very large number of cores, and they were designed to work in the latency hiding framework developed in this project. The effectiveness of the developments was enhanced by the direct application to real grand challenge simulation problems covering a wide range of technologically important applications, time scales and accuracies. These included the simulation of the electronic structure of mineral/fluid interfaces, the very accurate simulation of chemical reactions in microsolvated environments, and the simulation of chemical behavior in very large enzyme reactions.

Automatic Diabetic Macular Edema Detection in Fundus Images Using Publicly Available Datasets  

SciTech Connect

Diabetic macular edema (DME) is a common vision threatening complication of diabetic retinopathy. In a large scale screening environment DME can be assessed by detecting exudates (a type of bright lesions) in fundus images. In this work, we introduce a new methodology for diagnosis of DME using a novel set of features based on colour, wavelet decomposition and automatic lesion segmentation. These features are employed to train a classifier able to automatically diagnose DME. We present a new publicly available dataset with ground-truth data containing 169 patients from various ethnic groups and levels of DME. This and other two publicly available datasets are employed to evaluate our algorithm. We are able to achieve diagnosis performance comparable to retina experts on the MESSIDOR (an independently labelled dataset with 1200 images) with cross-dataset testing. Our algorithm is robust to segmentation uncertainties, does not need ground truth at lesion level, and is very fast, generating a diagnosis on an average of 4.4 seconds per image on an 2.6 GHz platform with an unoptimised Matlab implementation.

Dentalmaps: Automatic Dental Delineation for Radiotherapy Planning in Head-and-Neck Cancer  

SciTech Connect

Purpose: To propose an automatic atlas-based segmentation framework of the dental structures, called Dentalmaps, and to assess its accuracy and relevance to guide dental care in the context of intensity-modulated radiotherapy. Methods and Materials: A multi-atlas-based segmentation, less sensitive to artifacts than previously published head-and-neck segmentation methods, was used. The manual segmentations of a 21-patient database were first deformed onto the query using nonlinear registrations with the training images and then fused to estimate the consensus segmentation of the query. Results: The framework was evaluated with a leave-one-out protocol. The maximum doses estimated using manual contours were considered as ground truth and compared with the maximum doses estimated using automatic contours. The dose estimation error was within 2-Gy accuracy in 75% of cases (with a median of 0.9 Gy), whereas it was within 2-Gy accuracy in 30% of cases only with the visual estimation method without any contour, which is the routine practice procedure. Conclusions: Dose estimates using this framework were more accurate than visual estimates without dental contour. Dentalmaps represents a useful documentation and communication tool between radiation oncologists and dentists in routine practice.

AUTOMATIC DETECTION OF GRAVEL BARS IN A RIVER CHANNEL FROM AIRBORNE LIDAR-DERIVED DTM  

E-Print Network (OSTI)

Airborne Laser Scanning or LiDAR data are widely used nowadays in river valleys for topography and hydro-morphology. However, the large data sets of unprocessed 3D point clouds require some challenging treatment and end-users may prefer to deal with DTMs (Digital Terrain Models) derived from LiDAR surveys. Without any complementary data (such as field survey or photographs) detecting position and shape of gravel bars in a river is a demanding task, especially if done manually. This paper presents a method for automatic segmentation of a river channel into distinct hydro- morphological entities: water, gravel bars, banks,... This method is based on image processing algorithms (region growing segmentation combined with morphological closing and altitude thresholding) in order to separate water from other elements present in the channel, based on the altitude information. This method is applied to a reach of the Arcen-Maurienne River, France, with alternate gravel bars. The only data source is the 0.25 m resolution DTM, derived from an airborne LiDAR survey. Results show that the developed method succeeds in automatically delimiting the main channel and in detecting gravel bars. It is then possible to get global information on the gravel bars such as location along the river or emerged surface area and topography.

Sensors and Controls Research Sensors and Controls Research The Emerging Technologies team conducts research into technologies related to building sensors and controls. They work with building systems-such as a heating, ventilation, and air conditioning (HVAC) systems-to analyze energy use and help occupants manage energy costs. Building controls have the potential to reduce building energy consumption by monitoring variables and other inputs, and then automatically responding in a predetermined fashion. Research between the Department of Energy, industry, and laboratories focuses on: Sensors Photo of a ceiling-mounted fire sprinkler. Sensors are designed to help building owners and operators better manage their energy use through automation. Sensors measure predefined variables, such as the amount of natural light coming in through an office window, and then feed this data into a building's control system. The control can then respond by adjusting the various building systems. For example, sensors may note when a person leaves a room and let controls know to turn off the lights, or can ensure that faucets only release water if someone's hand is waved.

Performance of Personal Workspace Controls Final Report  

SciTech Connect

One of the key deliverables for the DOE-funded controls research at LBNL for FY04 was the development of a prototype Personal Workspace Control system. The successful development of this system is a critical milestone for the LBNL Lighting Controls Research effort because this system demonstrates how IBECS can add value to today's Task Ambient lighting systems. LBNL has argued that by providing both the occupant and the facilities manager with the ability to precisely control the operation of overhead lighting and all task lighting in a coordinated manner, that task ambient lighting can optimize energy performance and occupant comfort simultaneously [Reference Task Ambient Foundation Document]. The Personal Workspace Control system is the application of IBECS to this important lighting problem. This report discusses the development of the Personal Workspace Control to date including descriptions of the different fixture types that have been converted to IBECS operation and a detailed description of the operation of PWC Scene Controller, which provides the end user with precise control of his task ambient lighting system. The objective, from the Annual Plan, is to demonstrate improvements in efficiency, lighting quality and occupant comfort realized using Personal Workspace Controls (PWC) designed to optimize the delivery of lighting to the individual's workstation regardless of which task-ambient lighting solution is chosen. The PWC will be capable of controlling floor-mounted, desk lamps, furniture-mounted and overhead lighting fixtures from a personal computer and handheld remote. The PWC will use an environmental sensor to automatically monitor illuminance, temperature and occupancy and to appropriately modulate ambient lighting according to daylight availability and to switch off task lighting according to local occupancy. [Adding occupancy control to the system would blunt the historical criticism of occupant-controlled lighting - the tendency of the occupant to leave lights on]. The PWC will be an entirely open networking system in which all manufacturers of task lights, furniture-mounted lighting and ballast manufacturers can participate and have a business position.

The bridge-type fault current controller--a new facts controller  

Science Conference Proceedings (OSTI)

The operation of a novel current controller, which can also function as a fault current limiter and as a solid-state ac circuit breaker, is presented. The controller, which consists of a thyristor bridge, an inductor, and an optional bias power supply, is installed in series with the voltage source and the load, For load current values smaller than a preset value, the inductor of the current controller presents no impedance to the ac current flow. For values higher than the preset current value, the inductor is switched automatically into the ac circuit and limits the amount of current flow. Theoretical results in the form of circuit simulations and experimental results with a single-phase unit, operating on a 13.7 kV three-phase system with peak short-circuit currents of 3140 Arms, are presented.

High-Level Specification and Automatic Generation of IP Interface Monitors  

E-Print Network (OSTI)

A central problem in functional verification is to check that a circuit block is producing correct outputs while enforcing that the environment is providing legal inputs. To attack this problem, several researchers have proposed monitor-based methodologies, which offer many benefits. This paper presents a novel, high-level specification style for these monitors, along with a linear-size, linear-time translation algorithm into monitor circuits. The specification style naturally fits the complex, but well-specified interfaces used between IP blocks in systems-on-chip. To demonstrate the advantage of our specification style, we have specified monitors for various versions of the Sonics OCP protocol as well as the AMBA AHB protocol, and have developed a prototype tool that automatically translates specifications into Verilog or VHDL monitor circuits.

Automatic Scheduling of Outages of Nuclear Power Plants with Time Windows  

E-Print Network (OSTI)

We report on a successful project for transference of advanced AI technology into the domain of planning of outages of nuclear power plants as part of DOD's dual-use program. ROMAN (Rome Lab Outage Manager) is the prototype system that was developed as a result of this project. ROMAN's main innovation compared to the current state of the art of outage management tools is its capability to automatically enforce safety constraints during the planning and scheduling phase. Another innovative aspect of ROMAN is the generation of more robust schedules that are feasible over time windows. In other words, ROMAN generates a family of schedules by assigning time intervals as start times to activities rather than single point start times, without afecting the overall duration of the project. ROMAN uses a constraint satisfaction paradigm combining a global search tactic with constraint propagation.

Algorithm Summary and Evaluation: Automatic Implementation of Ringdown Analysis for Electromechanical Mode Identification from Phasor Measurements  

Science Conference Proceedings (OSTI)

Small signal stability problems are one of the major threats to grid stability and reliability. Prony analysis has been successfully applied on ringdown data to monitor electromechanical modes of a power system using phasor measurement unit (PMU) data. To facilitate an on-line application of mode estimation, this paper develops a recursive algorithm for implementing Prony analysis and proposed an oscillation detection method to detect ringdown data in real time. By automatically detecting ringdown data, the proposed method helps guarantee that Prony analysis is applied properly and timely on the ringdown data. Thus, the mode estimation results can be performed reliably and timely. The proposed method is tested using Monte Carlo simulations based on a 17-machine model and is shown to be able to properly identify the oscillation data for on-line application of Prony analysis. In addition, the proposed method is applied to field measurement data from WECC to show the performance of the proposed algorithm.

Automatic heart isolation for CT coronary visualization using graph-cuts  

E-Print Network (OSTI)

We describe a means to automatically and efficiently isolate the outer surface of the entire heart in Computer Tomography (CT) cardiac scans. Isolating the entire heart allows the coronary vessels on the surface of the heart to be easily visualized despite the proximity of surrounding organs such as the ribs and pulmonary blood vessels. Numerous techniques have been described for segmenting the left ventricle of the heart in images from various types of medical scanners but rarely has the entire heart been segmented. We make use of graphcuts to do the segmentation and introduce a novel means of initiating and constraining the graph-cut technique for heart isolation. The technique has been tested on 70 patient data sets. Results are compares with hand labeled results. 1.

Using PL/SQL to automatically enhance CASE*Generator 2.0 generated forms  

SciTech Connect

The SQL{trademark} Forms generator in CASE{trademark} Generator can generate forms with many useful capabilities. Generated forms can be further enhanced by the use of the CASE{trademark} Generator forms template. The template can be used to make these capabilities easily included in every form in a system. However, there are times when capabilities need to be added to all of the forms in a system, that cannot be implemented with the generator or template. This is especially true when generated block and field level triggers have to be modified. This paper describe how PL/SQL can be used to modify the generated forms. CASE{trademark} Generator can be configured to perform these modifications automatically. Three examples of modifications that have been made using this technique will also be detailed.

Development and Beam Tests of an Automatic Algorithm for Alignment of LHC Collimators with Embedded BPMS  

E-Print Network (OSTI)

Collimators with embedded Beam Position Monitor (BPM) buttons will be installed in the LHC during the upcoming long shutdown period. During the subsequent operation, the BPMs will allow the collimator jaws to be kept centered around the beam trajectory. In this manner, the best possible beam cleaning efficiency and machine protection can be provided at unprecedented higher beam energies and intensities. A collimator alignment algorithm is proposed to center the jaws automatically around the beam. The algorithm is based on successive approximation, as the BPM measurements are affected by non-linearities, which vary with the distance between opposite buttons, as well as the difference between the beam and the jaw centers. The successful test results, as well as some considerations for eventual operation in the LHC are also presented.

Scripting in Radiation Therapy: An Automatic 3D Beam-Naming System  

Science Conference Proceedings (OSTI)

Scripts can be executed within the radiation treatment planning software framework to reduce human error, increase treatment planning efficiency, reduce confusion, and promote consistency within an institution or even among institutions. Scripting is versatile, and one application is an automatic 3D beam-naming system that describes the position of the beam relative to the patient in 3D space. The naming system meets the need for nomenclature that is conducive for clear and accurate communication of beam entry relative to patient anatomy. In radiation oncology in particular, where miscommunication can cause significant harm to patients, a system that minimizes error is essential. Frequent sharing of radiation treatment information occurs not only among members within a department but also between different treatment centers. Descriptions of treatment beams are perhaps the most commonly shared information about a patient's course of treatment in radiation oncology. Automating the naming system by the use of a script reduces the potential for human error, improves efficiency, enforces consistency, and would allow an institution to convert to a new naming system with greater ease. This script has been implemented in the Department of Radiation Oncology at the University of Washington Medical Center since December 2009. It is currently part of the dosimetry protocol and is accessible by medical dosimetrists, radiation oncologists, and medical physicists. This paper highlights the advantages of using an automatic 3D beam-naming script to flawlessly and quickly identify treatment beams with unique names. Scripting in radiation treatment planning software has many uses and great potential for improving clinical care.

Digital multimode buck converter control with loss-minimizing synchronous rectifier adaptation  

E-Print Network (OSTI)

Abstract—This paper develops a multimode control strategy which allows for efficient operation of the buck converter over a wide load range. A method for control of synchronous rectifiers as a direct function of the load current is introduced [1]. The function relating the synchronous-rectifier timing to the load current is optimized on-line with a gradient power-loss-minimizing algorithm. Only low-bandwidth measurements of the load current and a power-loss-related quantity are required, making the technique suitable for digital controller implementations. Compared to alternative loss-minimizing approaches, this method has superior adjustment speed and robustness to disturbances, and can simultaneously optimize multiple parameters. The proposed synchronous-rectifier control also accomplishes an automatic, optimal transition to discontinuous-conduction mode at light load. Further, by imposing a minimum duty-ratio, the converter automatically enters pulse-skipping mode at very light load. Thus, the same controller structure can be used in both fixed-frequency pulsewidth modulation and variable-frequency pulse-skipping modes. These techniques are demonstrated on a digitally-controlled 100-W buck converter. Index Terms—Adaptive control, dead-time, digital control, gradient methods, multimode control, optimization methods, pulse skipping, pulsewidth modulated (PWM) power converters, pulsewidth modulation (PWM), synchronous rectifier (SR), variable frequency control.

Feedback-Controlled LED Photobioreactor for Photophysiological Studies of Cyanobacteria  

SciTech Connect

A custom photobioreactor (PBR) was designed to enable automatic light adjustments using computerized feedback control. A black anodized aluminum enclosure, constructed to surround the borosilicate reactor vessel, prevents the transmission of ambient light and serves as a mount for arrays of light-emitting diodes (LEDs). The high-output LEDs provide narrow-band light of either 630 or 680 nm for preferential excitation of the cyanobacterial light-harvesting pigments, phycobilin or chlorophyll a, respectively. Custom developed software BioLume provides automatic control of optical properties and a computer feedback loop can automatically adjust the incident irradiance as necessary to maintain a fixed transmitted light through the culture, based on user-determined set points. This feedback control serves to compensate for culture dynamics which have optical effects, (e.g., changing cell density, pigment adaptations) and thus can determine the appropriate light conditions for physiological comparisons or to cultivate light-sensitive strains, without prior analyses. The LED PBR may also be controlled as a turbidostat, using a feedback loop to continuously adjust the rate of media-dilution based on the transmitted light measurements, with a fast and precise response. This cultivation system gains further merit as a high-performance analytical device, using non-invasive tools (e.g., dissolved gas sensors, online mass spectrometry) to automate real-time measurements, thus permitting unsupervised experiments to search for optimal growth conditions, to monitor physiological responses to perturbations, as well as to quantitate photophysiological parameters using an in situ light-saturation response routine.

Heliogyro Control  

E-Print Network (OSTI)

Heliogyros with blade length-to-width aspect ratios of 1000 can achieve ambitious science mission goals, but such designs have not been analyzed with rigor. Archived heliogyro analyses indicate that aspect ratios of 1000 are feasible, but the calculations supporting this claim are based on the simplifying assumptions of decoupled twist, vertical deflection, and in-plane deflection of the blades. In making such simplifications, the equations become more tractable, but crucial behavioral characteristics are possibly lost. Without a more rigorous analytical investigation, the reliability and robustness of the heliogyro remains in doubt. However, with verified control models and an appropriate operations strategy, performance of aggressive heliogyro designs can be presumed. This thesis asserts that heliogyro blades with aspect ratios of 1000:1 can sufficiently operate in space. The crux of this investigation is a high-fidelity model that accurately represents a heliogyro blade. Pitch controls command the thrust vector of the large sail structure. Although the validation model mimics a real solar sail, the controller is driven toward the most simplified configuration. The results of this research validate that a model-based controller that neglects blade twist, coning, and wrinkling can sufficiently control the thrust vector of a suitably designed heliogyro.
