Wide-area situation awareness in electric power grid  

Science Conference Proceedings (OSTI)

Two primary elements of the US energy policy are demand management and efficiency and renewable sources. Major objectives are clean energy transmission and integration, reliable energy transmission, and grid cyber security. Development of the Smart Grid seeks to achieve these goals by lowering energy costs for consumers, achieving energy independence and reducing greenhouse gas emissions. The Smart Grid is expected to enable real time wide-area situation awareness (SA) for operators. Requirements for wide-area SA have been identified among interoperability standards proposed by the Federal Energy Regulatory Commission and the National Institute of Standards and Technology to ensure smart-grid functionality. Wide-area SA and enhanced decision support and visualization tools are key elements in the transformation to the Smart Grid. This paper discusses human factors research to promote SA in the electric power grid and the Smart Grid. Topics that will be discussed include the role of human factors in meeting US energy policy goals, the impact and challenges for Smart Grid development, and cyber security challenges.

Enhanced Energy-Aware Feedback Scheduling of Embedded Control Systems  

E-Print Network (OSTI)

Dynamic voltage scaling (DVS) is one of the most effective techniques for reducing energy consumption in embedded and real-time systems. However, traditional DVS algorithms have inherent limitations on their capability in energy saving since they rarely take into account the actual application requirements and often exploit fixed timing constraints of real-time tasks. Taking advantage of application adaptation, an enhanced energy-aware feedback scheduling (EEAFS) scheme is proposed, which integrates feedback scheduling with DVS. To achieve further reduction in energy consumption over pure DVS while not jeopardizing the quality of control, the sampling period of each control loop is adapted to its actual control performance, thus exploring flexible timing constraints on control tasks. Extensive simulation results are given to demonstrate the effectiveness of EEAFS under different scenarios. Compared with the optimal pure DVS scheme, EEAFS saves much more energy while yielding comparable control performance.

PILGRIM: a Location Broker and Mobility-Aware Recommendation System  

E-Print Network (OSTI)

Mobile computing adds a new, mostly unexplored dimension to data mining: the user's position is now a relevant information, and recommendation systems, i.e. services that select and rank a small number of links that are probably of interest to the user, have the opportunity to take location into account. The use of location discovery systems, that automatically detect the device location, relieve the user from the burden of explicitly inserting that information when formulating a query. In this paper, a mobility-aware recommendation system that uses the location of the user to filter recommended links is proposed. To avoid the potential problems and costs caused by systems where the bindings between locations and resources are inserted by hand, a new middleware layer, the location broker, collects a historic database where user locations and links explored in the past are mined to develop models relating resources to their spatial usage pattern. The models are used to calculate a preference metric when the current user is asking for resources of interest.

Minimum State Awareness for Resilient Control Systems Under Cyber-Attack  

Science Conference Proceedings (OSTI)

State awareness for a control system is the accurate knowledge of the internal states of the system realization. To maintain stable operation, a controller requires a certain degree of state awareness. By definition, a cyber-attacker decreases the state awareness by modifying or removing the information available to the operator and control system. By doing so, the attacker can directly cause damage to the physical system through the control system, or indirectly by causing the operator to react in a damaging manner to the false information. In a number of recent papers, detection and mitigation strategies have been proposed that assume state awareness. The goal of the attacker to reduce or remove state awareness makes this assumption invalid for most situations. One of the central problems of resilient control is developing methods to retain sufficient state awareness to continue operation during a cyberattack. In this paper, we will define state awareness, discuss the consequences of loss of state awareness, and some potential research directions for maintaining state awareness.

Power-Aware Operating Systems for Interactive Systems  

E-Print Network (OSTI)

Many portable systems deploy operating systems (OS) to support versatile functionality and to manage resources, including power. This paper presents a new approach for using OS to reduce the power consumption of IO devices in interactive systems. Low-power OS observes the relationship between hardware devices and processes. The OS kernel estimates the utilization of a device from each process. If a device is not used by any running process, the OS puts it into a low-power state. This paper also explains how scheduling can facilitate power management. When processes are properly scheduled, power reduction can be achieved without degrading performance. We implemented a prototype on Linux to control two devices; experimental results showed nearly 70% power saving on a network card and a hard disk drive.

Personalization in privacy-aware highly dynamic systems  

E-Print Network (OSTI)

Fifteen years after Mark Weiser’s inspiring paper on ubiquitous computing [ 1], his vision has become technically feasible. Objects of everyday use are becoming increasingly interconnected and mobile communication of all bandwidth and devices of all sizes are used in various ways. Highly dynamic information systems (HDS) are emerging, bringing new challenges for the management of information systems: having to cope with components that enter and leave the system spontaneously and be autonomous in their actions. The changing and possibly conflicting requirements of the single components have to be taken into account leading to a dynamic negotiation of requirements. Moreover, such highly dynamic systems have to be able to contend with constant growth of communicated data avidly collected in various forms. Solving the challenges of HDS is accompanied with a prospect of economic potential. A first realization is the present rollout of RFID by major retail groups worldwide Currently, cost savings through process automation is of prime importance but the use of this technology in retailing goes beyond mere productivity improvements.

Improving Control System Cyber-State Awareness using Known Secure Sensor Measurements  

SciTech Connect

Abstract—This paper presents design and simulation of a low cost and low false alarm rate method for improved cyber-state awareness of critical control systems - the Known Secure Sensor Measurements (KSSM) method. The KSSM concept relies on physical measurements to detect malicious falsification of the control systems state. The KSSM method can be incrementally integrated with already installed control systems for enhanced resilience. This paper reviews the previously developed theoretical KSSM concept and then describes a simulation of the KSSM system. A simulated control system network is integrated with the KSSM components. The effectiveness of detection of various intrusion scenarios is demonstrated on several control system network topologies.

Traffic flow wide-area surveillance system definition  

SciTech Connect

Traffic Flow Wide-Area Surveillance (TFWAS) is a system for assessing the state of traffic flow over a wide area for enhanced traffic control and improved traffic management and planning. The primary purpose of a TFWAS system is to provide a detailed traffic flow description and context description to sophisticated traffic management and control systems being developed or envisioned for the future. A successful TFWAS system must possess the attributes of safety, reconfigurability, reliability, and expandability. The primary safety premise of TFWAS is to ensure that no action or failure of the TFWAS system or its components can result in risk of injury to humans. A wide variety of communication techniques is available for use with TFWAS systems. These communication techniques can be broken down into two categories, landlines and wireless. Currently used and possible future traffic sensing technologies have been examined. Important criteria for selecting TFWAS sensors include sensor capabilities, costs, operational constraints, sensor compatibility with the infrastructure, and extent. TFWAS is a concept that can take advantage of the strengths of different traffic sensing technologies, can readily adapt to newly developed technologies, and can grow with the development of new traffic control strategies. By developing innovative algorithms that will take information from a variety of sensor types and develop descriptions of traffic flows over a wide area, a more comprehensive understanding of the traffic state can be provided to the control system to perform the most reasonable control actions over the entire wide area. The capability of characterizing the state of traffic over an entire region should revolutionize developments in traffic control strategies.

Reliability-aware dynamic energy management in dependable embedded real-time systems  

E-Print Network (OSTI)

Recent studies show that, voltage scaling, which is an efficient energy management technique, has a direct and negative effect on system reliability because of the increased rate of transient faults (e.g., those induced by cosmic particles). In this work, we propose energy management schemes that explicitly take system reliability into consideration. The proposed reliability-aware energy management schemes dynamically schedule recoveries for tasks to be scaled down to recuperate the reliability loss due to energy management. Based on the amount of available slack, the application size and the fault rate changes, we analyze when it is profitable to reclaim the slack for energy savings without sacrificing system reliability. Checkpoint technique is further explored to efficiently use the slack. Analytical and simulation results show that, the proposed schemes can achieve comparable energy savings as ordinary energy management schemes while preserving system reliability. The ordinary energy management schemes that ignore the effects of voltage scaling on fault rate changes could lead to drastically decreased system reliability.

TACO-DTN: A Time-Aware COntent-based dissemination system for Delay Tolerant Networks  

E-Print Network (OSTI)

Content dissemination applications are becoming more and more popular on fixed infrastructure: in this paper we introduce TACO-DTN, a content dissemination system which, by virtue of being time-aware in terms of subscriptions and events, is appropriate for delay tolerant networks, where a number of nodes act as infostations, enjoying some form of connectivity to the backbone, and other nodes are mobile devices, reachable sometimes only through intermittent connectivity of carriers. Examples of applications benefiting from such a system could be travel information dissemination systems in large cities (exploiting infostations at bus stops) or on highways, advertisements dissemination at specific times, and information dissemination to remote villages. The approach is based on a novel concept of temporal utility of subscriptions and events. The temporal utility is used to govern the routing of the events to the right infostation (i.e., the one reached by the interested subscribers at the right time), avoiding unnecessary information transfer on slow links and the buffer management, in case buffer limitations are an issue. We give a description of our protocol and discuss its validation through simulation.

Wide area network monitoring system for HEP experiments at Fermilab  

SciTech Connect

Large, distributed High Energy Physics (HEP) collaborations, such as D0, CDF and US-CMS, depend on stable and robust network paths between major world research centers. The evolving emphasis on data and compute Grids increases the reliance on network performance. Fermilab's experimental groups and network support personnel identified a critical need for WAN monitoring to ensure the quality and efficient utilization of such network paths. This has led to the development of the Network Monitoring system we will present in this paper. The system evolved from the IEPM-BW project, started at SLAC three years ago. At Fermilab this system has developed into a fully functional infrastructure with bi-directional active network probes and path characterizations. It is based on the Iperf achievable throughput tool, Ping and Synack to test ICMP/TCP connectivity. It uses Pipechar and Traceroute to test, compare and report hop-by-hop network path characterization. It also measures real file transfer performance by BBFTP and GridFTP. The Monitoring system has an extensive web-interface and all the data is available through standalone SOAP web services or by a MonaLISA client. Also in this paper we will present a case study of network path asymmetry and abnormal performance between FNAL and SDSC, which was discovered and resolved by utilizing the Network Monitoring system.

System-wide emissions implications of increased wind power penetration.  

DOE Green Energy (OSTI)

This paper discusses the environmental effects of incorporating wind energy into the electric power system. We present a detailed emissions analysis based on comprehensive modeling of power system operations with unit commitment and economic dispatch for different wind penetration levels. First, by minimizing cost, the unit commitment model decides which thermal power plants will be utilized based on a wind power forecast, and then, the economic dispatch model dictates the level of production for each unit as a function of the realized wind power generation. Finally, knowing the power production from each power plant, the emissions are calculated. The emissions model incorporates the effects of both cycling and start-ups of thermal power plants in analyzing emissions from an electric power system with increasing levels of wind power. Our results for the power system in the state of Illinois show significant emissions effects from increased cycling and particularly start-ups of thermal power plants. However, we conclude that as the wind power penetration increases, pollutant emissions decrease overall due to the replacement of fossil fuels.

Columbia River Hatchery Reform System-Wide Report.  

SciTech Connect

The US Congress funded the Puget Sound and Coastal Washington Hatchery Reform Project via annual appropriations to the US Fish and Wildlife Service (USFWS) beginning in fiscal year 2000. Congress established the project because it recognized that while hatcheries have a necessary role to play in meeting harvest and conservation goals for Pacific Northwest salmonids, the hatchery system was in need of comprehensive reform. Most hatcheries were producing fish for harvest primarily to mitigate for past habitat loss (rather than for conservation of at-risk populations) and were not taking into account the effects of their programs on naturally spawning populations. With numerous species listed as threatened or endangered under the Endangered Species Act (ESA), conservation of salmon in the Puget Sound area was a high priority. Genetic resources in the region were at risk and many hatchery programs as currently operated were contributing to those risks. Central to the project was the creation of a nine-member independent scientific review panel called the Hatchery Scientific Review Group (HSRG). The HSRG was charged by Congress with reviewing all state, tribal and federal hatchery programs in Puget Sound and Coastal Washington as part of a comprehensive hatchery reform effort to: conserve indigenous salmonid genetic resources; assist with the recovery of naturally spawning salmonid populations; provide sustainable fisheries; and improve the quality and cost-effectiveness of hatchery programs. The HSRG worked closely with the state, tribal and federal managers of the hatchery system, with facilitation provided by the non-profit organization Long Live the Kings and the law firm Gordon, Thomas, Honeywell, to successfully complete reviews of over 200 hatchery programs at more than 100 hatcheries across western Washington. That phase of the project culminated in 2004 with the publication of reports containing the HSRG's principles for hatchery reform and recommendations for Puget Sound/Coastal Washington hatchery programs, followed by the development in 2005 of a suite of analytical tools to support application of the principles (all reports and tools are available at www.hatcheryreform.us). In 2005, Congress directed the National Oceanic and Atmospheric Administration-Fisheries (NOAA Fisheries) to replicate the Puget Sound and Coastal Washington Hatchery Reform Project in the Columbia River Basin. The HSRG was expanded to 14 members to include individuals with specific knowledge about the Columbia River salmon and steelhead populations. This second phase was initially envisioned as a one-year review, with emphasis on the Lower Columbia River hatchery programs. It became clear however, that the Columbia River Basin needed to be viewed as an inter-connected ecosystem in order for the review to be useful. The project scope was subsequently expanded to include the entire Basin, with funding for a second year provided by the Bonneville Power Administration (BPA) under the auspices of the Northwest Power and Conservation Council's (NPCC) Fish and Wildlife Program. The objective of the HSRG's Columbia River Basin review was to change the focus of the Columbia River hatchery system. In the past, these hatchery programs have been aimed at supplying adequate numbers of fish for harvest as mitigation primarily for hydropower development in the Basin. A new, ecosystem-based approach is founded on the idea that harvest goals are sustainable only if they are compatible with conservation goals. The challenge before the HSRG was to determine whether or not conservation and harvest goals could be met by fishery managers and, if so, how. The HSRG determined that in order to address these twin goals, both hatchery and harvest reforms are necessary. The HSRG approach represents an important change of direction in managing hatcheries in the region. It provides a clear demonstration that current hatchery programs can indeed be redirected to better meet both conservation and harvest goals. For each Columbia River Basin Environmentally Si

The Wide-area Energy Management System Phase 2 Final Report  

DOE Green Energy (OSTI)

The higher penetration of intermittent generation resources (including wind and solar generation) in the Bonneville Power Administration (BPA) and California Independent System Operator (CAISO) balancing authorities (BAs) raises issue of requiring expensive additional fast grid balancing services in response to additional intermittency and fast up and down power ramps in the electric supply system. The overall goal of the wide-area energy management system (WAEMS) project is to develop the principles, algorithms, market integration rules, a functional design, and a technical specification for an energy storage system to help cope with unexpected rapid changes in renewable generation power output. The resulting system will store excess energy, control dispatchable load and distributed generation, and utilize inter-area exchange of the excess energy between the California ISO and Bonneville Power Administration control areas. A further goal is to provide a cost-benefit analysis and develop a business model for an investment-based practical deployment of such a system. There are two tasks in Phase 2 of the WAEMS project: the flywheel field tests and the battery evaluation. Two final reports, the Wide-area Energy Management System Phase 2 Flywheel Field Tests Final Report and the Wide-area Energy Storage and Management System Battery Storage Evaluation, were written to summarize the results of the two tasks.

Use of the WECC WAMS in Wide Area Probing Tests for Validation of System Performance & Modeling  

Science Conference Proceedings (OSTI)

During 2005 and 2006 the Western Electricity Coordinating Council (WECC) performed three major tests of western system dynamics. These tests used a Wide Area Measurement System (WAMS) based primarily on Phasor Measurement Units (PMUs) to determine response to events including the insertion of the 1400-MW Chief Joseph braking resistor, probing signals, and ambient events. Test security was reinforced through real-time analysis of wide area effects, and high-quality data provided dynamic profiles for interarea modes across the entire western interconnection. The tests established that low-level optimized pseudo-random ±20-MW probing with the Pacific DC Intertie (PDCI) roughly doubles the apparent noise that is natural to the power system, providing sharp dynamic information with negligible interference to system operations. Such probing is an effective alternative to use of the 1400-MW Chief Joseph dynamic brake, and it is under consideration as a standard means for assessing dynamic security.

A Fault-Tolerant Emergency-Aware Access Control Scheme for Cyber-Physical Systems  

E-Print Network (OSTI)

Access control is an issue of paramount importance in cyber-physical systems (CPS). In this paper, an access control scheme, namely FEAC, is presented for CPS. FEAC can not only provide the ability to control access to data in normal situations, but also adaptively assign emergency-role and permissions to specific subjects and inform subjects without explicit access requests to handle emergency situations in a proactive manner. In FEAC, emergency-group and emergency-dependency are introduced. Emergencies are processed in sequence within the group and in parallel among groups. A priority and dependency model called PD-AGM is used to select optimal response-action execution path aiming to eliminate all emergencies that occurred within the system. Fault-tolerant access control polices are used to address failure in emergency management. A case study of the hospital medical care application shows the effectiveness of FEAC.

The proposed solution situates 4 viewing systems in the equatorial ports 3, 9, 12, and 17 with 4 views each (looking at the upper target, the inner divertor, and tangentially left and right). This gives sufficient coverage. The spatial resolution of the divertor system is 2 times higher than the other views. For compensation of vacuum-vessel movements, an optical hinge concept is proposed. Compactness and low neutron streaming is achieved by orienting port plug doglegs horizontally. Calibration methods, risks, and R and D topics are outlined.

Power-aware scheduling and dynamic voltage setting for tasks running on a hard real-time system  

E-Print Network (OSTI)

Abstract- This paper addresses the problem of minimizing energy consumption of a computer system performing periodic hard real-time tasks with precedence constraints. In the proposed approach, dynamic power management and voltage scaling techniques are combined to reduce the energy consumption of the CPU and devices. The optimization problem is first formulated as an integer programming problem. Next, a three-phase solution framework, which integrates power management scheduling and task voltage assignment, is proposed. Experimental results show that the proposed approach outperforms existing methods by an average of 18 % in terms of the system-wide energy savings. I.

Barriers to a Wide-Area Trusted Network Early Warning System For Electric  

E-Print Network (OSTI)

It is apparent that perturbations of the North American electric power grid follow the patterns and characteristics of Self Organized Critical (SOC) systems. Published studies show SOC systems exhibit statistical properties that may result in early warning systems predicting electric power instability and loss of reliability. However, in order for such an early warning system to exist, a trusted wide-area data network must collate information from disparate subsystems and compile that information into homogenous data records for input to a modeling system. This paper explores similarities between widearea trusted computer networks and the needs of a widearea trusted network early warning system for electric power instability. An analysis of commercial equipment used in power stations uncovers disparate access methods and protocols that inhibit interoperability, and yet that problem has been mitigated in computer networking. Recent advances lend hope that wide-area data collection and modeling of electric power system perturbations will be commonplace in the not to distant future. I. Modeling Disturbance Data The electric power grid can be modeled as a complex system of dynamic load and generation balances characterized by two types of stability. Steady-state stability describes the nominal balancing of relatively minor disturbances in load/generation fluctuations caused by normal start-up and shut-down events associated with the millions of appliances and equipment attached to the grid. Constraints on operating parameters – nominally voltage levels, current magnitudes and power flows – are used to achieve steady-state equilibrium where the generation input is matched to system losses and electrical outputs. Whereas, transient stability describes the power systems ability (or lack thereof) to absorb major disturbances and return to a relatively balanced steadystate. Load shedding, generation shedding, and regional

Time Stamp Attack on Wide Area Monitoring System in Smart Grid  

E-Print Network (OSTI)

Security becomes an extremely important issue in smart grid. To maintain the steady operation for smart power grid, massive measurement devices must be allocated widely among the power grid. Previous studies are focused on false data injection attack to the smart grid system. In practice, false data injection attack is not easy to implement, since it is not easy to hack the power grid data communication system. In this paper, we demonstrate that a novel time stamp attack is a practical and dangerous attack scheme for smart grid. Since most of measurement devices are equipped with global positioning system (GPS) to provide the time information of measurements, it is highly probable to attack the measurement system by spoofing the GPS. By employing the real measurement data in North American Power Grid, simulation results demonstrate the effectiveness of the time stamp attack on smart grid.

The effectiveness of forest carbon sequestration strategies with system-wide adjustments, Resources for the Future  

E-Print Network (OSTI)

This paper addresses the effectiveness of tree planting and forest conservation strategies to increase the sink of carbon in global forests. Because forests are expected to sequester additional carbon without explicit human intervention, a baseline case is presented. The baseline predicts that forests will sequester an additional 17.9 Pg (10 15 grams) of carbon over the next 150 years, with nearly 95 % of this accruing to storage in marketed forest products. The paper then compares strategies which assume markets adjust to changes in future timber supply to an optimistic regional planner case in which no market adjustment occurs. The resulting predictions show that system wide market interactions may lead to substantial leakage of carbon from the forest system.

CLASS B2108+213: A new wide separation gravitational lens system  

E-Print Network (OSTI)

We present observations of CLASS B2108+213, the widest separation gravitational lens system discovered by the Cosmic Lens All-Sky Survey. Radio imaging using the VLA at 8.46 GHz and MERLIN at 5 GHz shows two compact components separated by 4.56 arcsec with a faint third component in between which we believe is emission from a lensing galaxy. 5-GHz VLBA observations reveal milliarcsecond-scale structure in the two lensed images that is consistent with gravitational lensing. Optical emission from the two lensed images and two lensing galaxies within the Einstein radius is detected in Hubble Space Telescope imaging. Furthermore, an optical gravitational arc, associated with the strongest lensed component, has been detected. Surrounding the system are a number of faint galaxies which may help explain the wide image separation. A plausible mass distribution model for CLASS B2108+213 is also presented.

Tomographic reconstruction for Wide Field Adaptive Optics systems: Fourier domain analysis and fundamental limitations  

E-Print Network (OSTI)

Several Wide Field of view Adaptive Optics (WFAO) concepts like Multi-Conjugate AO (MCAO), Multi-Object AO (MOAO) or Ground-Layer AO (GLAO) are currently studied for the next generation of Extremely Large Telescopes (ELTs). All these concepts will use atmospheric tomography to reconstruct the turbulent phase volume. In this paper, we explore different reconstruction algorithms and their fundamental limitations. We conduct this analysis in the Fourier domain. This approach allows us to derive simple analytical formulations for the different configurations, and brings a comprehensive view of WFAO limitations. We then investigate model and statistical errors and their impact on the phase reconstruction. Finally, we show some examples of different WFAO systems and their expected performance on a 42m telescope case.

The DOE Wide Area Measurement System (WAMS) Project: Demonstration of dynamic information technology for the future power system  

SciTech Connect

In 1989 the Bonneville Power Administration (BPA) and the Western Area Power Administration (WAPA) joined the US Department of Energy (DOE) in an assessment of longer-term research and development needs for future electric power system operation. The effort produced a progressively sharper vision of a future power system in which enhanced control and operation are the primary means for serving new customer demands, in an environment where increased competition, a wider range of services and vendors, and much narrower operating margins all contribute to increased system efficiencies and capacity. Technology and infrastructure for real time access to wide area dynamic information were identified as critical path elements in realizing that vision. In 1995 the DOE accordingly launched the Wide Area Measurement System (WAMS) Project jointly with the two Power Marketing Administrations (PMAs) to address these issues in a practical operating environment--the western North America power system. The Project draws upon many years of PMA effort and related collaboration among the western utilities, plus an expanding infrastructure that includes regionally involved contractors, universities, and National Laboratories plus linkages to the Electric Power Research Institute (EPRI). The WAMS project also brings added focus and resources to the evolving Western System Dynamic Information Network, or WesDINet. This is a collective response of the Western Systems Coordinating Council (WSCC) member utilities to their shared needs for direct information about power system characteristics, model fidelity, and operational performance. The WAMS project is a key source of the technology and backbone communications needed to make WesDINet a well integrated, cost effective enterprise network demonstrating the role of dynamic information technology in the emerging utility environment.

Design and Analysis of a Region-Wide Remotely Controllable Electrical Lock-Out System  

Science Conference Proceedings (OSTI)

Electric utilities have a main responsibility to protect the lives and safety of their workers when they are working on low-, medium-, and high-voltage power lines and distribution circuits. With the anticipated widespread deployment of smart grids, a secure and highly reliable means of maintaining isolation of customer-owned distributed generation (DG) from the affected distribution circuits during maintenance is necessary to provide a fully de-energized work area, ensure utility personnel safety, and prevent hazards that can lead to accidents such as accidental electrocution from unanticipated power sources. Some circuits are serviced while energized (live line work) while others are de-energized for maintenance. For servicing de-energized circuits and equipment, lock-out tag-out (LOTO) programs provide a verifiable procedure for ensuring that circuit breakers are locked in the off state and tagged to indicate that status to operational personnel so that the lines will be checked for voltage to verify they are de-energized. The de-energized area is isolated from any energized sources, which traditionally are the substations. This procedure works well when all power sources and their interconnections are known armed with this knowledge, utility personnel can determine the appropriate circuits to de-energize for isolating the target line or equipment. However, with customer-owned DG tied into the grid, the risk of inadvertently reenergizing a circuit increases because circuit connections may not be adequately documented and are not under the direct control of the local utility. Thus, the active device may not be properly de-energized or isolated from the work area. Further, a remote means of de-energizing and locking out energized devices provides an opportunity for greatly reduced safety risk to utility personnel compared to manual operations. In this paper, we present a remotely controllable LOTO system that allows individual workers to determine the configuration and status of electrical system circuits and permit them to lock out customer-owned DG devices for safety purposes using a highly secure and ultra-reliable radio signal. The system consists of: (1) individual personal lockout devices, (2) lockout communications and logic module at circuit breakers, which are located at all DG devices, and (3) a database and configuration control process located at the utility operations center. The lockout system is a close permissive, i.e., loss of control power or communications will cause the circuit breaker to open. Once the DG device is tripped open, a visual means will provide confirmation of a loss of voltage and current that verifies the disconnected status of the DG. Further the utility personnel will be able to place their own lock electronically on the system to ensure a lockout functionally. The proposed LOTO system provides enhanced worker safety and protection against unintended energized lines when DG is present. The main approaches and challenges encountered through designing the proposed region-wide LOTO system are discussed in this paper. These approaches include: (1) evaluating the reliability of the proposed approach under N-modular redundancy with voter/spares configurations and (2) conducting a system level risk assessment study using the failure modes and effects analysis (FMEA) technique to identify and rank failure modes by probability of occurrence, probability of detection, and severity of consequences. This ranking allows a cost benefits analysis to be conducted such that dollars and efforts will be applied to the failures that provide greatest incremental gains in system capability (resilience, survivability, security, reliability, availability, etc.) per dollar spent whether capital, operations, or investment. Several simulation scenarios and their results are presented to demonstrate the viability of these approaches.

Microfabricated BTU monitoring device for system-wide natural gas monitoring.  

SciTech Connect

The natural gas industry seeks inexpensive sensors and instrumentation to rapidly measure gas heating value in widely distributed locations. For gas pipelines, this will improve gas quality during transfer and blending, and will expedite accurate financial accounting. Industrial endusers will benefit through continuous feedback of physical gas properties to improve combustion efficiency during use. To meet this need, Sandia has developed a natural gas heating value monitoring instrument using existing and modified microfabricated components. The instrument consists of a silicon micro-fabricated gas chromatography column in conjunction with a catalytic micro-calorimeter sensor. A reference thermal conductivity sensor provides diagnostics and surety. This combination allows for continuous calorimetric determination with a 1 minute analysis time and 1.5 minute cycle time using air as a carrier gas. This system will find application at remote natural gas mining stations, pipeline switching and metering stations, turbine generators, and other industrial user sites. Microfabrication techniques will allow the analytical components to be manufactured in production quantities at a low per-unit cost.

Interference-aware ieee 802.16 wimax mesh networks  

E-Print Network (OSTI)

Abstract — The IEEE 802.16 WiMax standard provides a mechanism for creating multi-hop mesh, which can be deployed as a high speed wide-area wireless network. To realize the full potential of such high-speed IEEE 802.16 mesh networks, two efficient wireless radio resource allocation extensions were developed. The objective of this paper is to propose an efficient approach for increasing the utilization of WiMax mesh through appropriate design of multi-hop routing and scheduling. As multiple-access interference is a major limiting factor for wireless communication systems, we adopt here an interference-aware cross-layer design to increase the throughput of the wireless mesh network. In particular, our scheme creates a tree-based routing framework, which along with scheduling is interference aware and results in a much higher spectral efficiency. Performance evaluation results show that the proposed interference-aware scheme achieves significant throughput enhancement over the basic IEEE 802.16 mesh network.

E-AMOM: An Energy-Aware Modeling and Optimization Methodology for Scientific Applications on Multicore Systems  

E-Print Network (OSTI)

Power consumption is an important constraint in achieving efficient execution on High Performance Computing Multicore Systems. As the number of cores available on a chip continues to increase, the importance of power consumption will continue to grow. In order to achieve improved performance on multicore systems scientific applications must make use of efficient methods for reducing power consumption and must further be refined to achieve reduced execution time. In this dissertation, we introduce a performance modeling framework, E-AMOM, to enable improved execution of scientific applications on parallel multicore systems with regards to a limited power budget. We develop models for each application based upon performance hardware counters. Our models utilize different performance counters for each application and for each performance component (runtime, system power consumption, CPU power consumption, and memory power consumption) that are selected via our performance-tuned principal component analysis method. Models developed through E-AMOM provide insight into the performance characteristics of each application that affect performance for each component on a parallel multicore system. Our models are more than 92% accurate across both Hybrid (MPI/OpenMP) and MPI implementations for six scientific applications. E-AMOM includes an optimization component that utilizes our models to employ run-time Dynamic Voltage and Frequency Scaling (DVFS) and Dynamic Concurrency Throttling to reduce power consumption of the scientific applications. Further, we optimize our applications based upon insights provided by the performance models to reduce runtime of the applications. Our methods and techniques are able to save up to 18% in energy consumption for Hybrid (MPI/OpenMP) and MPI scientific applications and reduce the runtime of the applications up to 11% on parallel multicore systems.

PRELIMINARY RESULTS FROM NEOWISE: AN ENHANCEMENT TO THE WIDE-FIELD INFRARED SURVEY EXPLORER FOR SOLAR SYSTEM SCIENCE  

SciTech Connect

The Wide-field Infrared Survey Explorer (WISE) has surveyed the entire sky at four infrared wavelengths with greatly improved sensitivity and spatial resolution compared to its predecessors, the Infrared Astronomical Satellite and the Cosmic Background Explorer. NASA's Planetary Science Division has funded an enhancement to the WISE data processing system called 'NEOWISE' that allows detection and archiving of moving objects found in the WISE data. NEOWISE has mined the WISE images for a wide array of small bodies in our solar system, including near-Earth objects (NEOs), Main Belt asteroids, comets, Trojans, and Centaurs.

Nuclear magnetic resonance wide-line study of hydrogen in the yttrium-yttrium dihydride system

The /sup 1/H nuclear magnetic resonance was studied in the yttrium-hydrogen system YH/sub x/ in the composition range 0.20 less than or equal to x less than or equal to 1.98 and temperature range 77 K less than or equal to T less than or equal to 490/sup 0/K. Both ..cap alpha..- and ..beta..-phases of YH/sub x/ were investigated in polycrystalline (powdered) specimens. Rigid lattice proton resonance second moments were obtained for both ..cap alpha..- and ..beta..-phase samples. Analysis of the second moment for ..cap alpha..-YH/sub x/ (..cap alpha..-phase) indicates that the hydrogen resides in both the tetrahedral and octahedral interstitial sites of the hcp Y lattice. Second moment values for ..beta..-YH/sub x/ (..beta..-phase) indicate that a sizeable fraction of the octahedral interstitial sites in the fcc yttrium metal lattice are occupied by hydrogen, while a nonnegligible fraction of the tetrahedral interstitial sites are vacant. For example, in YH/sub 1.98/, 28% of the octahedral sites are occupied, while 15% of the tetrahedral sites are vacant. The results for ..beta..-YH/sub x/ also indicate that as the H concentration increases, the probability of H occupation of octahedral sites increases.

The ITER VIS/IR wide angle viewing system: Challenges and on-going R and D  

SciTech Connect

The ITER tokamak is the next generation fusion device which will allow studying burning plasma obtained by a Deuterium-Tritium (D-T) fusion reaction during hundreds of seconds. ITER vacuum vessel real-time protection will be mandatory during plasma operation to avoid water leaks and critical plasma facing components degradation. The protection system will be based on a wide angle viewing system (WAVS) composed with 18 visible (VIS) and 18 infrared (IR) cameras covering 80 % of the vacuum vessel which will be one of the major imaging systems of ITER. Compared to protection systems routinely used on current tokamaks and based on imaging (VIS and/or IR), new constraints must be taken into account because of their influence on the system performance: the harsh environment (high neutron flux) and the metallic plasma facing components (both first wall and divertor). In this new demanding context, we have achieved three mandatory R and D studies starting from the understanding of the source of signals by using realistic photonic simulation up to real-time processing strategy taken into account first order optical design constraints to define what type of performance could be reached for ITER vacuum vessel protection.

Researching Complex Heat, Air and Moisture Interactions for a Wide-Range of Building Envelope Systems and Environmental Loads  

Science Conference Proceedings (OSTI)

This document serves as the final report documenting work completed by Oak Ridge National Laboratory (ORNL) and the Fraunhofer Institute in Building Physics (Holzkirchen, Germany) under an international CRADA No. 0575 with Fraunhofer Institute of Bauphysics of the Federal Republic of Germany for Researching Complex Heat, Air and Moisture Interactions for a Wide Range of Building Envelope Systems and Environmental Loads. This CRADA required a multi-faceted approach to building envelope research that included a moisture engineering approach by blending extensive material property analysis, laboratory system and sub-system thermal and moisture testing, and advanced moisture analysis prediction performance. The Participant's Institute for Building physics (IBP) and the Contractor's Buildings Technology Center (BTC) identified potential research projects and activities capable of accelerating and advancing the development of innovative, low energy and durable building envelope systems in diverse climates. This allowed a major leverage of the limited resources available to ORNL to execute the required Department of Energy (DOE) directives in the area of moisture engineering. A joint working group (ORNL and Fraunhofer IBP) was assembled and a research plan was executed from May 2000 to May 2005. A number of key deliverables were produced such as adoption of North American loading into the WUFI-software. in addition the ORNL Weather File Analyzer was created and this has been used to address environmental loading for a variety of US climates. At least 4 papers have been co-written with the CRADA partners, and a chapter in the ASTM Manual 40 on Moisture Analysis and Condensation Control. All deliverables and goals were met and exceeded making this collaboration a success to all parties involves.

Computationally Efficient Neural Network Intrusion Security Awareness  

SciTech Connect

An enhanced version of an algorithm to provide anomaly based intrusion detection alerts for cyber security state awareness is detailed. A unique aspect is the training of an error back-propagation neural network with intrusion detection rule features to provide a recognition basis. Network packet details are subsequently provided to the trained network to produce a classification. This leverages rule knowledge sets to produce classifications for anomaly based systems. Several test cases executed on ICMP protocol revealed a 60% identification rate of true positives. This rate matched the previous work, but 70% less memory was used and the run time was reduced to less than 1 second from 37 seconds.

Development of Design Guidelines for Soil Embedded Post Systems Using Wide-flange I-beam to Contain Truck Impact  

E-Print Network (OSTI)

Anti ram perimeter barriers are part of the protection of important facilities such as power plants, air ports and embassies against unrestricted vehicle access. Many different systems can be used to achieve the containment goal. One of these systems makes use of soil embedded posts either single posts if the soil is hard enough or groups of soil embedded posts tied together by beams if the soil is not hard enough for a single post to stop the in-coming truck. The design of these soil embedded posts needs to take account a number of influencing factors which include the soil strength and stiffness, the post strength and stiffness, the mass of the vehicle and its approach velocity. This dissertation describes the work done to develop a set of design recommendations to select the embedment of a single post or group of posts. The post is a steel beam with an H shape cross section: W14X109 for the single post system and W14X90 for the group system with a double beam made of square hollow steel section HSS8X8X1/2. The spacing of the posts for the group includes 2.44 m, 4.88 m, and 7.32 m. The soil strength varies from loose sand and soft clay to very dense sand and very hard clay. The vehicle has a mass of 6800 kg and the velocities include 80 km/h, 65 km/h, and 50 km/h. The design guidelines presented here are based on 10 medium scale pendulum impact tests, 2 medium scale bogie impact tests, 1 full scale impact test on a single post, 1 full scale impact test on a group of 8 side by side posts with a 5.2 m spacing and connected with two beams, approximately 150 4-D numerical simulations of full scale impact tests using LS-DYNA, as well as fundamental theoretical concepts.

Development of an Enterprise-wide Energy Information and Utility Monitoring System in a Major Hotel Chain: The Hyatt Hotels Corporation Experience  

E-Print Network (OSTI)

Hyatt Hotels Corporation is currently implementing an enterprise-wide Energy Information and Utility Monitoring System (UMS). New Horizon Technologies and eComponents Technology have teamed to provide an integrated solution that will ultimately include all Hyatt Hotels in North America. In addition, these 120 Hyatt Hotels participate in a monthly web-based energy benchmarking and hotel engineering reporting system. For hotels with Utility Monitoring Systems (UMS) installed, energy and water consumption data is automatically summarized for the web reports. Hotels without the UMS enter monthly utility data manually on the website. The base UMS at the hotels consists of electric, gas and domestic water consumption and local temperature and relative humidity measurements. The Hyatt UMS is one of the first enterprise-wide systems to include domestic water metering. Many hotels elect to install additional sub-metering for major loads or end uses such as chillers, kitchens and laundries. The local hotel UMS consists of a data acquisition system capable of displaying real-time data that also logs 15-minute interval data. The system transfers interval data daily, to a data center and also transfers interval data hourly, via a Local Area Network, to an on-site workstation with a local database. The local workstation permits users to have real-time alarming capability, access to easy-touse data visualization and analysis tools, and the ability to generate both customized and standard daily and monthly reports. Report writing and utility costing software are used to generate daily and month-to-date cost reports. Bill estimation software uses actual utility rate tariff models to create estimates of utility costs for any custom defined period. Data resident in the Hyatt data center is accessible to the individual hotels using a web-based system. Senior engineers with authorization can access data for all Hyatt Hotels in their regions. The corporate energy director and senior management have access to all data in the Hyatt data center. Browser-based hotel benchmarking data is also available through a similar system with an authorization hierarchy. This paper will describe the design and implementation of the Hyatt UMS in detail, review how the system is currently being used by Hyatt personnel, discuss potential future applications and provide an initial look at UMS system-wide data, including a preliminary return on investment (ROI) analysis.

Architecture-Aware Algorithms for Scalable Performance and Resilience on Heterogeneous Architectures  

SciTech Connect

The goal of the Extreme-scale Algorithms & Software Institute (EASI) is to close the ?application-architecture performance gap? by exploring algorithms and runtime improvements that will enable key science applications to better exploit the architectural features of DOE extreme-scale systems. For the past year of the project, our efforts at the University of Tennessee have concentrated on, and made significant progress related to, the following high-level EASI goals: ? Develop multi-precision and architecture-aware implementations of Krylov, Poisson, Helmholtz solvers, and dense factorizations for heterogeneous multi-core systems; ? Explore new methods of algorithm resilience, and develop new algorithms with these capabilities; ? Develop runtime support for adaptable algorithms that are dealing with resilience, scalability; ? Distribute the new algorithms and runtime support through widely used software packages; ? Establish a strong outreach program to disseminate results, interact with colleagues and train students and junior members of our community.

Layout-Aware I/O Scheduling for Terabits Data Movement  

Science Conference Proceedings (OSTI)

Many science facilities, such as the Department of Energy s Leadership Computing Facilities and experimental facilities including the Spallation Neutron Source, Stanford Linear Accelerator Center, and Advanced Photon Source, produce massive amounts of experimental and simulation data. These data are often shared among the facilities and with collaborating institutions. Moving large datasets over the wide- area network (WAN) is a major problem inhibiting collaboration. Next- generation, terabit-networks will help alleviate the problem, however, the parallel storage systems on the end-system hosts at these institutions can become a bottleneck for terabit data movement. The parallel storage system (PFS) is shared by simulation systems, experimental systems, analysis and visualization clusters, in addition to wide-area data movers. These competing uses often induce temporary, but significant, I/O load imbalances on the storage system, which impact the performance of all the users. The problem is a serious concern because some resources are more expensive (e.g. super computers) or have time-critical deadlines (e.g. experimental data from a light source), but parallel file systems handle all requests fairly even if some storage servers are under heavy load. This paper investigates the problem of competing workloads accessing the parallel file system and how the performance of wide-area data movement can be improved in these environments. First, we study the I/O load imbalance problems using actual I/O performance data collected from the Spider storage system at the Oak Ridge Leadership Computing Facility. Second, we present I/O optimization solutions with layout-awareness on end-system hosts for bulk data movement. With our evaluation, we show that our I/O optimization techniques can avoid the I/O congested disk groups, improving storage I/O times on parallel storage systems for terabit data movement.

Thermo-mechanical analysis of ITER first mirrors and its use for the ITER equatorial visible/infrared wide angle viewing system optical design  

SciTech Connect

ITER first mirrors (FMs), as the first components of most ITER optical diagnostics, will be exposed to high plasma radiation flux and neutron load. To reduce the FMs heating and optical surface deformation induced during ITER operation, the use of relevant materials and cooling system are foreseen. The calculations led on different materials and FMs designs and geometries (100 mm and 200 mm) show that the use of CuCrZr and TZM, and a complex integrated cooling system can limit efficiently the FMs heating and reduce their optical surface deformation under plasma radiation flux and neutron load. These investigations were used to evaluate, for the ITER equatorial port visible/infrared wide angle viewing system, the impact of the FMs properties change during operation on the instrument main optical performances. The results obtained are presented and discussed.

Wide-Area Energy Storage and Management system to Balance Intermittent Resources in the Bonneville Power Administration and California ISO Control Areas  

DOE Green Energy (OSTI)

The entire project addresses the issue of mitigating additional intermittency and fast ramps that occur at higher penetration of intermittent resources, including wind genera-tion, in the Bonneville Power Administration (BPA) and the California Independent Sys-tem Operator (California ISO) control areas. The proposed Wide Area Energy Storage and Management System (WAEMS) will address the additional regulation requirement through the energy exchange between the participating control areas and through the use of energy storage and other generation resources. For the BPA and California ISO control centers, the new regulation service will look no different comparing with the traditional regulation resources. The proposed project will benefit the regulation service in these service areas, regardless of the actual degree of penetration of the intermittent resources in the regions. The project develops principles, algorithms, market integration rules, functional de-sign and technical specifications for the WAEMS system. The project is sponsored by BPA and supported in kind by California ISO, Beacon Power Corporation, and the Cali-fornia Energy Commission (CEC).

Development of a Context Aware Virtual Smart Home Simulator  

E-Print Network (OSTI)

Context awareness is the most important research area in ubiquitous computing. In particular, for smart home, context awareness attempts to bring the best services to the home habitants. However, the implementation in the real environment is not easy and takes a long time from building the scratch. Thus, to support the implementation in the real smart home, it is necessary to demonstrate that thing can be done in the simulator in which context information can be created by virtual sensors instead of physical sensors. In this paper, we propose ISS, an Interactive Smart home Simulator system aiming at controlling and simulating the behavior of an intelligent house. The developed system aims to provide architects, designers a simulation and useful tool for understanding the interaction between environment, people and the impact of embedded and pervasive technology on in daily life. In this research, the smart house is considered as an environment made up of independent and distributed devices interacting to supp...

THE HUBBLE WIDE FIELD CAMERA 3 TEST OF SURFACES IN THE OUTER SOLAR SYSTEM: THE COMPOSITIONAL CLASSES OF THE KUIPER BELT  

SciTech Connect

We present the first results of the Hubble Wide Field Camera 3 Test of Surfaces in the Outer Solar System. The purpose of this survey was to measure the surface properties of a large number of Kuiper Belt objects and attempt to infer compositional and dynamical correlations. We find that the Centaurs and the low-perihelion scattered disk and resonant objects exhibit virtually identical bifurcated optical color distributions and make up two well-defined groups of objects. Both groups have highly correlated optical and NIR colors that are well described by a pair of two-component mixture models that have different red components but share a common neutral component. The small, H{sub 606} {approx}> 5.6 high-perihelion excited objects are entirely consistent with being drawn from the two branches of the mixing model, suggesting that the color bifurcation of the Centaurs is apparent in all small excited objects. On the other hand, objects larger than H{sub 606} {approx} 5.6 are not consistent with the mixing model, suggesting some evolutionary process avoided by the smaller objects. The existence of a bifurcation amongst all excited populations argues that the two separate classes of object existed in the primordial disk before the excited Kuiper Belt was populated. The cold classical objects exhibit a different type of surface that has colors that are consistent with being drawn from the red branch of the mixing model, but with much higher albedos.

Social networks and context-aware spam  

E-Print Network (OSTI)

Social networks are popular for online communities. This paper evaluates the risk of sophisticated context-aware spam that could result from information sharing on social networks and discusses potential mitigation strategies. Unlike normal spam, context-aware spam would likely have a high click-through rate due to exploitation of authentic social connections. Context-aware spam could lead to more insidious attacks that try to install malware or steal passwords. In this paper, we analyzed Facebook, a popular social networking website. Our goal was to determine how many users were vulnerable to context-aware attack email and understand aspects of Facebook's design that make such attacks possible. We also classified different kinds of email attacks based on certain pieces of data such as birthdays, lists of friends, wall posts, and user news feeds. We analyzed Facebook starting from a single university e-mail address to calculate the number of users who would be vulnerable to each type of attack. We found that a hacker could send sophisticated context-aware email to approximately 85 % of users. Furthermore, our analysis shows that people with private profiles are almost equally vulnerable to a subset of attacks. Finally, we discuss defense strategies. Some strategies would require users to coordinate their privacy policies with each other. We also suggest design improvements for social networks that may help reduce exposure to context-aware attack email.

This is especially the fact as small and mobile nodes become available and application scenarios emerge, which lead to much higher requirements in terms of reliability, longterm operability, adaptation, and self-organization. In this paper, we focus on energy control and battery management in mobile robot systems. We show an approximation technique to derive the remaining energy of the local system. The mechanism is based on a model of all energy-consuming parts of the robot system and the corresponding characteristic curves. The results are used for task allocation and behavior adaptation of each autonomously acting system. The proposed methodology increases the probability of completing globally assigned tasks. Therefore, the algorithm contributes to the performance and reliability of the global system. Additionally, each node in the overall system becomes able to employ its energy resources much more efficiently. We see this energy-aware concept for task allocation as a basis for further extensions used for studies on energy efficient communication in mobile sensor networks. 1

Wide-Bandgap Semiconductors  

SciTech Connect

With the increase in demand for more efficient, higher-power, and higher-temperature operation of power converters, design engineers face the challenge of increasing the efficiency and power density of converters [1, 2]. Development in power semiconductors is vital for achieving the design goals set by the industry. Silicon (Si) power devices have reached their theoretical limits in terms of higher-temperature and higher-power operation by virtue of the physical properties of the material. To overcome these limitations, research has focused on wide-bandgap materials such as silicon carbide (SiC), gallium nitride (GaN), and diamond because of their superior material advantages such as large bandgap, high thermal conductivity, and high critical breakdown field strength. Diamond is the ultimate material for power devices because of its greater than tenfold improvement in electrical properties compared with silicon; however, it is more suited for higher-voltage (grid level) higher-power applications based on the intrinsic properties of the material [3]. GaN and SiC power devices have similar performance improvements over Si power devices. GaN performs only slightly better than SiC. Both SiC and GaN have processing issues that need to be resolved before they can seriously challenge Si power devices; however, SiC is at a more technically advanced stage than GaN. SiC is considered to be the best transition material for future power devices before high-power diamond device technology matures. Since SiC power devices have lower losses than Si devices, SiC-based power converters are more efficient. With the high-temperature operation capability of SiC, thermal management requirements are reduced; therefore, a smaller heat sink would be sufficient. In addition, since SiC power devices can be switched at higher frequencies, smaller passive components are required in power converters. Smaller heat sinks and passive components result in higher-power-density power converters. With the advent of the use of SiC devices it is imperative that models of these be made available in commercial simulators. This enables power electronic designers to simulate their designs for various test conditions prior to fabrication. To build an accurate transistor-level model of a power electronic system such as an inverter, the first step is to characterize the semiconductor devices that are present in the system. Suitable test beds need to be built for each device to precisely test the devices and obtain relevant data that can be used for modeling. This includes careful characterization of the parasitic elements so as to emulate the test setup as closely as possible in simulations. This report is arranged as follows: Chapter 2--The testing and characterization of several diodes and power switches is presented. Chapter 3--A 55-kW hybrid inverter (Si insulated gate bipolar transistor--SiC Schottky diodes) device models and test results are presented. A detailed description of the various test setups followed by the parameter extraction, modeling, and simulation study of the inverter performance is presented. Chapter 4--A 7.5-kW all-SiC inverter (SiC junction field effect transistors (JFET)--SiC Schottky diodes) was built and tested. The models built in Saber were validated using the test data and the models were used in system applications in the Saber simulator. The simulation results and a comparison of the data from the prototype tests are discussed in this chapter. Chapter 5--The duration test results of devices utilized in buck converters undergoing reliability testing are presented.

Battery-Aware Power Management Based on Markovian Decision Processes  

E-Print Network (OSTI)

This paper addresses the problem of maximizing the utilization of the battery capacity of the power source for a portable electronic system under a given performance constraint. A new stochastic model of a power-managed battery-powered electronic system is proposed, which is based on continuous-time Markovian decision processes (CTMDP). In this model, two important characteristics of today's rechargeable battery cells, i.e., the current rate-capacity characteristic and the relaxation-induced recovery are considered for. In addition, system properties, such as workload statistics and performance constraints are properly captured. The battery-aware power management problem is formulated as a policy optimization problem based on the theories of CTMDP and stochastic networks and solved exactly using a linear programming approach. Experimental results shows that our method outperforms existing heuristic methods for battery management by as much as 17% in terms of the average energy delivered per unit weight of battery cells.

Global-Aware and Multi-Order Context-Based Prefetching for High-Performance Processors  

Science Conference Proceedings (OSTI)

Data prefetching is widely used in high-end computing systems to accelerate data accesses and to bridge the increasing performance gap between processor and memory. Context-based prefetching has become a primary focus of study in recent years due to its general applicability. However, current context-based prefetchers only adopt the context analysis of a single order, which suffers from low prefetching coverage and thus limits the overall prefetching effectiveness. Also, existing approaches usually consider the context of the address stream from a single instruction but not the context of the address stream from all instructions, which further limits the context-based prefetching effectiveness. In this study, we propose a new context-based prefetcher called the Global-aware and Multi-order Context-based (GMC) prefetcher. The GMC prefetcher uses multi-order, local and global context analysis to increase prefetching coverage while maintaining prefetching accuracy. In extensive simulation testing of the SPEC-CPU2006 benchmarks with an enhanced CMP$im simulator, the proposed GMC prefetcher was shown to outperform existing prefetchers and to reduce the data-access latency effectively. The average Instructions Per Cycle (IPC) improvement of SPEC CINT2006 and CFP2006 benchmarks with GMC prefetching was over 55% and 44% respectively.

New insights into the pleiotropic drug resistance network from genome-wide characterization of the YRR1 transcription factor regulation system  

E-Print Network (OSTI)

Yrr1p is a recently described Zn 2Cys 6 transcription factor involved in the pleiotropic drug resistance (PDR) phenomenon. It is controlled in a Pdr1p-dependent manner and is autoregulated. We describe here a new genome-wide approach to characterization of the set of genes directly regulated by Yrr1p. We found that the time-course production of an artificial chimera protein containing the DNA-binding domain of Yrr1p activated the 15 genes that are also up-regulated by a gain-of-function mutant of Yrr1p. Gel mobility shift assays showed that the promoters of the genes AZR1, FLR1, SNG1, YLL056C, YLR346C, and YPL088W interacted with Yrr1p. The putative consensus Yrr1p binding site deduced from these experiments, (T/A)CCG(C/T)(G/T)(G/T)(A/ T)(A/T), is strikingly similar to the PDR element binding site sequence recognized by Pdr1p and Pdr3p. The minor differences between these sequences are consistent with Yrr1p and Pdr1p and Pdr3p having different sets of target genes. According to these data, some target genes are directly regulated by Pdr1p and Pdr3p or by Yrr1p, whereas some genes are indirectly regulated by the activation of Yrr1p. Some genes, such as YOR1, SNQ2, and FLR1, are clearly directly controlled by both classes of transcription factor, suggesting an important role for the corresponding membrane proteins. Multidrug resistance (MDR) in tumor cells, resulting in the failure of chemotherapy, remains a major obstacle to the successful

TOWARDS A GENDER-AWARE ENERGY POLICY  

E-Print Network (OSTI)

A women needs a man Like a fish needs a bicycle When you’re tryin ’ to throw your arms around the world ‘Tryin ’ To Throw Your Arms Around The World’, U2 Despite the efforts of South Africa and Uganda to genderize their energy policy, a clear idea what engendering energy policy is about is still lacking. There is not much knowledge on what its main characteristics are and how national governments can genderize their energy policy. Governments, civil society and development organizations, do not know how to realize gender mainstreaming in this area. The experience of South Africa in genderizing their energy policy and the attempts of the Ugandan government to integrate gender in their energy policy document could provide an example for other governments. The main objective of this study is therefore to contribute to the formulation of a gender-aware energy policy, which could help to overcome gender-inequality in national energy policy by developing and defining the main characteristics of gender-aware nation al energy policy and analyzing under which conditions such a policy can be realized.

Mission-Aware Medium Access Control in Random Access Networks  

E-Print Network (OSTI)

We study mission-critical networking in wireless communication networks, where network users are subject to critical events such as emergencies and crises. If a critical event occurs to a user, the user needs to send necessary information for help as early as possible. However, most existing medium access control (MAC) protocols are not adequate to meet the urgent need for information transmission by users in a critical situation. In this paer, we propose a novel class of MAC protocols that utilize available past information as well as current information. Our proposed protocols are mission-aware since they prescribe different transmission decision rules to users in different situations. We show that the proposed protocols perform well not only when the system faces a critical situation but also when there is no critical situation. By utilizing past information, the proposed protocols coordinate transmissions by users to achieve high throughput in the normal phase of operation and to let a user in a critical ...

Sustainable Energy Solutions Task 2.0: Wind Turbine Reliability and Maintainability Enhancement through System-wide Structure Health Monitoring and Modifications to Rotating Components  

DOE Green Energy (OSTI)

EXECUTIVE SUMARRY An evaluation of nondestructive structural health monitoring methods was completed with over 132 documents, 37 specifically about wind turbines, summarized into a technology matrix. This matrix lists the technology, what can be monitored with this technology, and gives a short summary of the key aspects of the technology and its application. Passive and active acoustic emission equipment from Physical Acoustics Corp. and Acellent Technologies have been evaluated and selected for use in experimental state loading and fatigue tests of composite wind turbine blade materials. Acoustic Emission (AE) and Active Ultrasonic Testing (AUT), were applied to composite coupons with both simulated and actual damage. The results found that, while composites are more complicated in nature, compared to metallic structures, an artificial neural network analysis could still be used to determine damage. For the AE system, the failure mode could be determined (i.e. fiber breakage, delamination, etc.). The Acellent system has been evaluated to work well with composite materials. A test-rig for reliability testing of the rotating components was constructed. The research on the types of bearings used in the wind turbines indicated that in most of the designs, the main bearings utilized to support the shaft are cylindrical roller bearings. The accelerated degradation testing of a population of bearings was performed. Vibration and acoustic emission data was collected and analyzed in order to identify a representative degradation signal for each bearing to identify the initiation of the degradation process in the bearings. Afterwards, the RMS of the vibration signal from degradation initiation up to the end of the useful life of the bearing was selected to predict the remaining useful life of the bearing. This step included fitting Autoregressive Moving Average (ARMA) models to the degradation signals and approximating the probability distribution function (PDF) of remaining useful life based on the results of Monte-Carlo simulation of the ARMA models. This step was performed for different percentages of the degradation signal of each bearing. The accuracy of the proposed approach then was assessed by comparing the actual life of the bearing and the estimated life of the bearing from the developed models. The results were impressive and indicated that the accuracy of the models improved as more data was utilized in developing the ARMA models (we get closer to the end of the life of the bearing).

Development of a System-Wide Predator Control Program: Stepwise Implementation of a Predation Index, Predator Control Fisheries, and Evaluation Plan in the Columbia River Basin; Northern Pikeminnow Management Program, 2002 Annual Report.  

SciTech Connect

This report presents results for year twelve in a basin-wide program to harvest northern pikeminnow1 (Ptychocheilus oregonensis). This program was started in an effort to reduce predation by northern pikeminnow on juvenile salmonids during their emigration from natal streams to the ocean. Earlier work in the Columbia River Basin suggested predation by northern pikeminnow on juvenile salmonids might account for most of the 10-20% mortality juvenile salmonids experience in each of eight Columbia River and Snake River reservoirs. Modeling simulations based on work in John Day Reservoir from 1982 through 1988 indicated that, if predator-size northern pikeminnow were exploited at a 10-20% rate, the resulting restructuring of their population could reduce their predation on juvenile salmonids by 50%. To test this hypothesis, we implemented a sport-reward angling fishery and a commercial longline fishery in the John Day Pool in 1990. We also conducted an angling fishery in areas inaccessible to the public at four dams on the mainstem Columbia River and at Ice Harbor Dam on the Snake River. Based on the success of these limited efforts, we implemented three test fisheries on a system-wide scale in 1991--a tribal longline fishery above Bonneville Dam, a sport-reward fishery, and a dam-angling fishery. Low catch of target fish and high cost of implementation resulted in discontinuation of the tribal longline fishery. However, the sport-reward and dam-angling fisheries were continued in 1992 and 1993. In 1992, we investigated the feasibility of implementing a commercial longline fishery in the Columbia River below Bonneville Dam and found that implementation of this fishery was also infeasible. Estimates of combined annual exploitation rates resulting from the sport-reward and damangling fisheries remained at the low end of our target range of 10-20%. This suggested the need for additional effective harvest techniques. During 1991 and 1992, we developed and tested a modified (small-sized) Merwin trapnet. We found this floating trapnet to be very effective in catching northern pikeminnow at specific sites. Consequently, in 1993 we examined a system-wide fishery using floating trapnets, but found this fishery to be ineffective at harvesting large numbers of northern pikeminnow on a system-wide scale.

PB-LRU: a self-tuning power aware storage cache replacement algorithm for conserving disk energy  

E-Print Network (OSTI)

Energy consumption is an important concern at data centers, where storage systems consume a significant fraction of the total energy. A recent study proposed power-aware storage cache management to provide more opportunities for the underlying disk power management scheme to save energy. However, the on-line algorithm proposed in that study requires cumbersome parameter tuning for each workload and is therefore difficult to apply to real systems. This paper presents a new power-aware on-line algorithm called PB-LRU (Partition-Based LRU) that requires little parameter tuning. Our results with both real system and synthetic workloads show that PB-LRU without any parameter tuning provides similar or even better performance and energy savings than the previous power-aware algorithm with the best parameter setting for each workload.

An Infrastructure for Distributed Computing and Context Aware Computing  

E-Print Network (OSTI)

This paper focuses what we see as main issues in context awareness, small size and low power of today's mobile computing devices. Until now, these devices are heterogenous and mostly used standalone to accomplish certain task. That means there is no a single generic type device and user needs to be aware of different devices to perform different tasks, which is of course practically inconvenient. We propose a generic device and a network infrastructure which address low power consumption, context aware computing and protable device for the ubiquitous computing environment. Where the generic device (as a mobile device) interacts with the different distributed devices which are fixed in the physical infrastructure.

Context-aware middleware for pervasive and ad hoc environments  

E-Print Network (OSTI)

Abstract: Recent advances in the area of mobile computing and pervasive computing have driven the emergence of new challenges. For example, the “Intelligent Environment ” or “Smart Environment ” has become one of the key research areas in the pervasive computing arena. These scenarios typically consist of intelligent rooms capable of gathering raw sensory data from embedded “invisible ” sensors, then processing and analysing them to deduce highlevel context and infer personal preferences (for room temperature, light intensity, type and level of music, etc.) Mobile and ad hoc scenarios also include time-critical applications such as an automatic car control systems in which cars are able to operate independently and cooperate with each other to avoid collisions. Another example is an air traffic control system whereby thousands of aircraft are proactively coordinated to keep them at safe distances from each other. In this paper, we present a context-aware middleware architecture for the support of both pervasive and ad hoc environments. The approach makes use of both reflection and component technology. A prototype of the middleware has been implemented in OpenCOM, which is a lightweight, efficient and reflective component model based on Microsoft’s COM. 1.

Temperature-aware computer systems: opportunities and challenges  

E-Print Network (OSTI)

Published by the IEEE Computer Society In recent years, power density in microprocessors has doubled every three years, and experts expect this rate to increase within one to two generations as feature sizes and frequencies scale faster than operating voltages. Because a microprocessor consumes energy and converts it into heat, the corresponding exponential rise in heat density is creating significant difficulties in maintaining reliability and low manufacturing cost. Any design must remove heat from the surface of the microprocessor die, and for all but the lowest-power designs today, such cooling solutions have become very expensive.

Leakage-Aware Reallocation for Periodic Real-Time Tasks on Multicore Processors  

E-Print Network (OSTI)

It is an increasingly important issue to reduce the energy consumption of computing systems. In this paper, we consider partition based energy-aware scheduling of periodic real-time tasks on multicore processors. The scheduling exploits dynamic voltage scaling (DVS) and core sleep scheduling to reduce both dynamic and leakage energy consumption. If the overhead of core state switching is non-negligible, however, the performance of this scheduling strategy in terms of energy efficiency might degrade. To achieve further energy saving, we extend the static task scheduling with run-time task reallocation. The basic idea is to aggregate idle time among cores so that as many cores as possible could be put into sleep in a way that the overall energy consumption is reduced. Simulation results show that the proposed approach results in up to 20% energy saving over traditional leakage-aware DVS.

Waste Minimization and Pollution Prevention Awareness Plan  

SciTech Connect

The purpose of this plan is to document Lawrence Livermore National Laboratory (LLNL) projections for present and future waste minimization and pollution prevention. The plan specifies those activities and methods that are or will be used to reduce the quantity and toxicity of wastes generated at the site. It is intended to satisfy Department of Energy (DOE) requirements. This Plan provides an overview of projected activities from FY 1994 through FY 1999. The plans are broken into site-wide and problem-specific activities. All directorates at LLNL have had an opportunity to contribute input, to estimate budget, and to review the plan. In addition to the above, this plan records LLNL`s goals for pollution prevention, regulatory drivers for those activities, assumptions on which the cost estimates are based, analyses of the strengths of the projects, and the barriers to increasing pollution prevention activities.

Wide Bandgap Extrinsic Photoconductive Switches  

SciTech Connect

Photoconductive semiconductor switches (PCSS) have been investigated since the late 1970s. Some devices have been developed that withstand tens of kilovolts and others that switch hundreds of amperes. However, no single device has been developed that can reliably withstand both high voltage and switch high current. Yet, photoconductive switches still hold the promise of reliable high voltage and high current operation with subnanosecond risetimes. Particularly since good quality, bulk, single crystal, wide bandgap semiconductor materials have recently become available. In this chapter we will review the basic operation of PCSS devices, status of PCSS devices and properties of the wide bandgap semiconductors 4H-SiC, 6H-SiC and 2H-GaN.

Multicore Architecture-aware Scientific Applications  

SciTech Connect

Modern high performance systems are becoming increasingly complex and powerful due to advancements in processor and memory architecture. In order to keep up with this increasing complexity, applications have to be augmented with certain capabilities to fully exploit such systems. These may be at the application level, such as static or dynamic adaptations or at the system level, like having strategies in place to override some of the default operating system polices, the main objective being to improve computational performance of the application. The current work proposes two such capabilites with respect to multi-threaded scientific applications, in particular a large scale physics application computing ab-initio nuclear structure. The first involves using a middleware tool to invoke dynamic adaptations in the application, so as to be able to adjust to the changing computational resource availability at run-time. The second involves a strategy for effective placement of data in main memory, to optimize memory access latencies and bandwidth. These capabilties when included were found to have a significant impact on the application performance, resulting in average speedups of as much as two to four times.

Solar-Aware clustering in wireless sensor networks

Energy conservation plays a crucial in wireless sensor networks since such networks are designed to be placed in hostile and non-accessible areas. While battery-driven sensors will run out of battery sooner or later, the use of renewable energy sources such as solar power or gravitation may extend the lifetime of a sensor network. We propose to utilize solar power in wireless sensor networks and extend LEACH a well-known cluster-based protocol for sensor networks to become solar-aware. The presented simulation results show that making LEACH solar-aware significantly extends the lifetime of sensor networks. 1

Exploiting Redundancy to Conserve Energy in Storage Systems  

E-Print Network (OSTI)

This paper makes two main contributions. First, it introduces Diverted Accesses, a technique that leverages the redundancy in storage systems to conserve disk energy. Second, it evaluates the previous (redundancy-oblivious) energy conservation techniques, along with Diverted Accesses, as a function of the amount and type of redundancy in the system. The evaluation is based on novel analytic models of the energy consumed by the techniques. Using these energy models and previous models of reliability, availability, and performance, we can determine the best redundancy configuration for new energy-aware storage systems. To study Diverted Accesses for realistic systems and workloads, we simulate a wide-area storage system under two file-access traces. Our modeling results show that Diverted Accesses is more effective and robust than the redundancy-oblivious techniques. Our simulation results show that our technique can conserve 20-61 % of the disk energy consumed by the wide-area storage system.

Human Factors and Data Fusion as Part of Control Systems Resilience  

Science Conference Proceedings (OSTI)

Human performance and human decision making is counted upon as a crucial aspect of overall system resilience. Advanced control systems have the potential to provide operators and asset owners a wide range of data, deployed at different levels that can be used to support operator situation awareness. However, the sheer amount of data available can make it challenging for operators to assimilate information and respond appropriately. This paper reviews some of the challenges and issues associated with providing operators with actionable state awareness and argues for the over arching importance of integrating human factors as part of intelligent control systems design and implementation. It is argued that system resilience is improved by implementing human factors in operations and maintenance. This paper also introduces issues associated with resilience and data fusion and highlights areas in which human factors including field studies hold promise.

Analyzing and minimizing the impact of opportunity cost in QoS-aware job scheduling.  

Science Conference Proceedings (OSTI)

Quality of service (QoS) mechanisms allowing users to request for turn-around time guarantees for their jobs have recently generated much interest. In our previous work we had designed a framework, QoPS, to allow for such QoS. This framework provides an admission control mechanism that only accepts jobs whose requested deadlines can be met and, once accepted, guarantees these deadlines. However, the framework is completely blind to the revenue these jobs can fetch for the supercomputer center. By accepting a job, the supercomputer center might relinquish its capability to accept some future arriving (and potentially more expensive) jobs. In other words, while each job pays an explicit price to the system for running it, the system may also be viewed as paying an implicit opportunity cost by accepting the job. Thus, accepting a job is profitable only when the job's price is higher than its opportunity cost. In this paper we analyze the impact such opportunity cost can have on the overall revenue of the supercomputer center and attempt to minimize it through predictive techniques. Specifically, we propose two extensions to QoPS, Value-aware QoPS (VQoPS) and Dynamic Value-aware QoPS (DVQoPS), to provide such capabilities. We present detailed analysis of these schemes and demonstrate using simulation that they not only achieve several factors improvement in system revenue, but also good service differentiation as a much desired side-effect.

Integration of space weather into space situational awareness  

SciTech Connect

Rapid assessment of space weather effects on satellites is a critical step in anomaly resolution and satellite threat assessment. That step, however, is often hindered by a number of factors including timely collection and delivery of space weather data and the inherent com plexity of space weather information. As part of a larger, integrated space situational awareness program, Los Alamos National Laboratory has developed prototype operational space weather tools that run in real time and present operators with customized, user-specific information. The Dynamic Radiation Environment Assimilation Model (DREAM) focuses on the penetrating radiation environment from natural or nuclear-produced radiation belts. The penetrating radiation environment is highly dynamic and highly orbit-dependent. Operators often must rely only on line plots of 2 MeV electron flux from the NOAA geosynchronous GOES satellites which is then assumed to be representative of the environment at the satellite of interest. DREAM uses data assimilation to produce a global, real-time, energy dependent specification. User tools are built around a distributed service oriented architecture (SOA) which will allow operators to select any satellite from the space catalog and examine the environment for that specific satellite and time of interest. Depending on the application operators may need to examine instantaneous dose rates and/or dose accumulated over various lengths of time. Further, different energy thresholds can be selected depending on the shielding on the satellite or instrument of interest. In order to rapidly assess the probability that space weather was the cause of anomalous operations, the current conditions can be compared against the historical distribution of radiation levels for that orbit. In the simplest operation a user would select a satellite and time of interest and immediately see if the environmental conditions were typical, elevated, or extreme based on how often those conditions occur in that orbit. This allows users to rapidly rule in or out environmental causes of anomalies. The same user interface can also allow users to drill down for more detailed quantitative information. DREAM can be run either from a distributed web-based user interface or as a stand-alone application for secure operations. In this paper we discuss the underlying structure of the DREAM model and demonstrate the user interface that we have developed . We also present some prototype data products and user interfaces for DREAM and discuss how space environment information can be seamlessly integrated into operational SSA systems.

Energy-Aware Task Partitioning on Heterogeneous Multiprocessor Platforms  

E-Print Network (OSTI)

Efficient task partitioning plays a crucial role in achieving high performance at multiprocessor plat forms. This paper addresses the problem of energy-aware static partitioning of periodic real-time tasks on heterogeneous multiprocessor platforms. A Particle Swarm Optimization variant based on Min-min technique for task partitioning is proposed. The proposed approach aims to minimize the overall energy consumption, meanwhile avoid deadline violations. An energy-aware cost function is proposed to be considered in the proposed approach. Extensive simulations and comparisons are conducted in order to validate the effectiveness of the proposed technique. The achieved results demonstrate that the proposed partitioning scheme significantly surpasses previous approaches in terms of both number of iterations and energy savings.

Energy Aware Scheduling for Weighted Completion Time and Weighted Tardiness  

E-Print Network (OSTI)

The ever increasing adoption of mobile devices with limited energy storage capacity, on the one hand, and more awareness of the environmental impact of massive data centres and server pools, on the other hand, have both led to an increased interest in energy management algorithms. The main contribution of this paper is to present several new constant factor approximation algorithms for energy aware scheduling problems where the objective is to minimize weighted completion time plus the cost of the energy consumed, in the one machine non-preemptive setting, while allowing release dates and deadlines.Unlike previous known algorithms these new algorithms can handle general job-dependent energy cost functions, extending the application of these algorithms to settings outside the typical CPU-energy one. These new settings include problems where in addition, or instead, of energy costs we also have maintenance costs, wear and tear, replacement costs, etc., which in general depend on the speed at which the machine r...

Framework for Real-Time All-Hazards Global Situational Awareness  

Science Conference Proceedings (OSTI)

Information systems play a pivotal role in emergency response by making consequence analysis models based on up-to-date data available to decision makers. While consequence analysis models have been used for years on local scales, their application on national and global scales has been constrained by lack of non-proprietary data. This chapter describes how this has changed using a framework for real-time all-hazards situational awareness called the Energy Awareness and Resiliency Standardized Services (EARSS) as an example. EARSS is a system of systems developed to collect non-proprietary data from diverse open content sources to develop a geodatabase of critical infrastructures all over the world. The EARSS system shows that it is feasible to provide global disaster alerts by producing valuable information such as texting messages about detected hazards, emailing reports about affected areas, estimating an expected number of impacted people and their demographic characteristics, identifying critical infrastructures that may be affected, and analyzing potential downstream effects. This information is provided in real-time to federal agencies and subscribers all over the world for decision making in humanitarian assistance and emergency response. The system also uses live streams of power outages, weather, and satellite surveillance data as events unfold. This, in turn, is combined with other public domain or open content information, such as media reports and postings on social networking websites, for complete coverage of the situation as events unfold. Working with up-to-date information from the EARSS system, emergency responders on the ground could pre-position their staff and resources, such as emergency generators and ice, where they are most needed.

Development of a System-Wide Predator Control Program : Stepwise Implementation of a Predation Index Predator Control Fisheries and Evaluation Plan in the Columbia River Basin, 1990 Annual Report.  

DOE Green Energy (OSTI)

The papers in this document report the results of studies to develop a Columbia River basin-wide program to control northern squawfish predation on juvenile salmonids. Our studies focus on (1) determining where in the basin northern squawfish predation is a problem, (2) conducting various fisheries for northern squawfish, and (3) testing a plan to evaluate how well fisheries are controlling northern squawfish populations. These studies were initiated as part of a basin-wide effort to reduce mortality of juvenile salmonids on their journey from natal streams to the ocean. Earlier work in the Columbia River basin suggested predation by northern squawfish on juvenile salmonids may account for most of the 10 to 20 percent mortality juvenile salmonids experience in each of eight Columbia and Snake river reservoirs. Modeling simulations based on work in John Day Reservoir from 1982--1988 indicated it is not necessary to eradicate northern squawfish to substantially reduce predation-caused mortality of juvenile salmonids. Instead, if northern squawfish were exploited at a 20 percent rate, reductions in their numbers and restructuring of their populations could reduce their predation on juvenile salmonids by 50 percent. We tested three fisheries in 1990, a tribal long-line fishery, a recreational-reward fishery, and a dam hook-and-line fishery.

MORA: an Energy-Aware Slack Reclamation Scheme for Scheduling Sporadic Real-Time Tasks upon Multiprocessor Platforms  

E-Print Network (OSTI)

In this paper, we address the global and preemptive energy-aware scheduling problem of sporadic constrained-deadline tasks on DVFS-identical multiprocessor platforms. We propose an online slack reclamation scheme which profits from the discrepancy between the worst- and actual-case execution time of the tasks by slowing down the speed of the processors in order to save energy. Our algorithm called MORA takes into account the application-specific consumption profile of the tasks. We demonstrate that MORA does not jeopardize the system schedulability and we show by performing simulations that it can save up to 32% of energy (in average) compared to execution without using any energy-aware algorithm.

Agency-Wide Screening Agency-Wide Screening Agency-Wide Screening October 16, 2013 - 4:36pm Addthis Federal agencies face energy-related requirements on new construction projects and major renovations. These Federal requirements range from reductions in fossil-fuel use to specifying the use of certain renewable energy technologies. As some agencies have already found out, not all sites or construction projects are created equal. Because many of the requirements are agency-wide, an effective and efficient way to meet these requirements is to consider and identify appropriate locations for these technologies across all agency land and building assets. FEMP can help Federal agencies conduct a renewable energy screening at all of its sites, or just at all of its upcoming construction project

Global situational awareness and early warning of high-consequence climate change.  

SciTech Connect

Global monitoring systems that have high spatial and temporal resolution, with long observational baselines, are needed to provide situational awareness of the Earth's climate system. Continuous monitoring is required for early warning of high-consequence climate change and to help anticipate and minimize the threat. Global climate has changed abruptly in the past and will almost certainly do so again, even in the absence of anthropogenic interference. It is possible that the Earth's climate could change dramatically and suddenly within a few years. An unexpected loss of climate stability would be equivalent to the failure of an engineered system on a grand scale, and would affect billions of people by causing agricultural, economic, and environmental collapses that would cascade throughout the world. The probability of such an abrupt change happening in the near future may be small, but it is nonzero. Because the consequences would be catastrophic, we argue that the problem should be treated with science-informed engineering conservatism, which focuses on various ways a system can fail and emphasizes inspection and early detection. Such an approach will require high-fidelity continuous global monitoring, informed by scientific modeling.

Interference-Aware Fair Rate Control in Wireless Sensor Networks  

E-Print Network (OSTI)

In a wireless sensor network of N nodes transmitting data to a single base station, possibly over multiple hops, what distributed mechanisms should be implemented in order to dynamically allocate fair and efficient transmission rates to each node? Our interference-aware fair rate control (IFRC) detects incipient congestion at a node by monitoring the average queue length, communicates congestion state to exactly the set of potential interferers using a novel low-overhead congestion sharing mechanism, and converges to a fair and efficient rate using an AIMD control law. We evaluate IFRC extensively on a 40-node wireless sensor network testbed. IFRC achieves a fair and efficient rate allocation that is within 20- 40% of the optimal fair rate allocation on some network topologies. Its rate adaptation mechanism is highly effective: we did not observe a single instance of queue overflow in our many experiments. Finally, IFRC can be extended easily to support situations where only a subset of the nodes transmit, where the network has multiple base stations, or where nodes are assigned different transmission weights.In a wireless sensor network of N nodes transmitting data to a single base station, possibly over multiple hops, what distributed mechanisms should be implemented in order to dynamically allocate fair and efficient transmission rates to each node?

In this paper we present a “Framework for Power Aware Remote Processing ‘ ‘ to minimize the energy consumption of mobile devices transparently. The main difference to remote processing frameworks already published consists in a novel integrated dynamic Power Estimation Unit. This is an adaptive power consumption estimator, which estimates the energy consumption of sojiware and system components. Based on the estimated power consumption an intelligent power manager migrates software components from the mobile device to remote machines, thus reducing the energy consumption of the mobile device.

U.S. Council for Energy Awareness 1992-1993  

Science Conference Proceedings (OSTI)

This report of the US Council for Energy Awareness covers the following main topics. (1) Electricity and Economic growth: growth of these has been roughly parallel. New electric generating capacity will be needed if the US is to sustain economic growth. All resources - coal, oil, natural gas, renewables, energy efficiency, and nuclear energy - have a role to play. (2) Nuclear Energy and the Environment: Nuclear energy is one of the cleanest sources of electric power. (3) Nuclear Power and Energy Independence: Nuclear energy is partly responsible for the dramatic reduction in oil use by electric utilities over the past 20 years. (4) Nuclear Energy: Insurance for the future: As US utilities plan to meet the growing need for electric power, they face major uncertainties (increased competion; the extent that demand-side management and efficiency can reduce need; future price and supply of natural gas; impact of the 1990 Clean Air Act amendments; possibility of increased fossil fuel restrictions) Nuclear energy represents prudent, strategic planning against these uncertainties.

A Case Study of Wide Diameter Casing for Geothermal Systems  

SciTech Connect

Three wells have been drilled in the central resistivity area of a geothermal field in the Taupo Volcanic Zone, New Zealand. Using a well bore simulator, WELL SIM V3.0, reservoir conditions and well characteristics are evaluated to determine the increase in output by increasing production casing diameters from either 8-5/8 inches OD or 9-5/8 inches OD to 13-3/8 inches OD. Increases in well drilling costs are determined to provide a commentary on the economics. While open hole size is effectively doubled, well costs increase by 10% and, in this study, output increases by an average of 18%.

Distributed Robust Power System State Estimation  

E-Print Network (OSTI)

Deregulation of energy markets, penetration of renewables, advanced metering capabilities, and the urge for situational awareness, all call for system-wide power system state estimation (PSSE). Implementing a centralized estimator though is practically infeasible due to the complexity scale of an interconnection, the communication bottleneck in real-time monitoring, regional disclosure policies, and reliability issues. In this context, distributed PSSE methods are treated here under a unified and systematic framework. A novel algorithm is developed based on the alternating direction method of multipliers. It leverages existing PSSE solvers, respects privacy policies, exhibits low communication load, and its convergence to the centralized estimates is guaranteed even in the absence of local observability. Beyond the conventional least-squares based PSSE, the decentralized framework accommodates a robust state estimator. By exploiting interesting links to the compressive sampling advances, the latter jointly es...

Awareness and knowledge of methylmercury in fish in the United States  

Science Conference Proceedings (OSTI)

In the 1970s several states in the Great Lakes region became concerned about mercury contamination in lakes and rivers and were the first to issue local fish consumption advisories. In 2001, the Food and Drug Administration (FDA) advised pregnant women, nursing mothers, young children, and women who may become pregnant not to consume shark, swordfish, king mackerel, and tilefish and recommended that these women not exceed 12 ounces of other fish per week. In 2004, FDA reissued this advice jointly with the U.S. Environmental Protection Agency (EPA) and modified it slightly to provide information about consumption of canned tuna and more details about consumption of recreationally caught fish. Though several studies have examined consumers' awareness of the joint FDA and EPA advisory as well as different state advisories, few used representative data. We examined the changes in awareness and knowledge of mercury as a problem in fish using the pooled nationally representative 2001 and 2006 Food Safety Surveys (FSS) with sample sizes of 4482 in 2001 and 2275 in 2006. Our results indicated an increase in consumers' awareness of mercury as a problem in fish (69% in 2001 to 80% in 2006, p<.001). In our regression models, we found that in both years, parents having children less than 5 years of age were more aware of mercury in fish and knowledgeable about the information contained in the national advisories about mercury in fish (p<.01) than other adults. In both 2001 and 2006, women of childbearing age (aged 18-45) were less aware and knowledgeable about this information than other women. However, women of all age groups had larger gains in awareness and knowledge than their male counterparts during this time. Participants' race, education, income, region, fish preparation experiences, having a foodborne illness in the past year, and risk perceptions about the safety of food were significant predictors of their awareness and knowledge. - Research highlights: {yields} We examined changes in awareness and knowledge of mercury as a problem in fish. {yields} Data are from the 2001 and 2006 Food Safety Surveys (FSS). {yields} Consumers' awareness of mercury as a problem in fish increased from 2001 to 2006. {yields} Demographics were significant predictors of awareness and knowledge.

Plant Wide Assessment for SIFCO Industries, Inc.  

Science Conference Proceedings (OSTI)

Sifco Industries carreid out a plant wide energy assessment under a collaborative program with the U.S. Department of Energy during October 2004 to September 2005. During the year, personnel from EIS, E3M, DPS, BuyCastings.Com, and Sifco plant facilities and maintenance personnel, as a team collected energy use, construction, process, equipment and operational information about the plant. Based on this information, the team identified 13 energy savings opportunities. Near term savings opportunities have a total potential savings of about $1,329,000 per year and a combined simple payback of about 11 months. Implementation of these recommendations would reduce CO2 emissions by about 16,000,000 pounds per year, which would reduce overall plant CO2 emissions by about 45%. These totals do not include another $830,000 per year in potential savings with an estimated 9-month payback, from converting the forging hammers from steam to compressed air.

Development of Autonomous Magnetometer Rotorcraft For Wide Area Assessment  

SciTech Connect

Large areas across the United States and internationally are potentially contaminated with unexploded ordinance (UXO), with some ranges encompassing tens to hundreds of thousands of acres. Technologies are needed which will allow for cost effective wide area scanning with (1) near 100% coverage and (2) near 100% detection of subsurface ordnance or features indicative of subsurface ordnance. The current approach to wide area assessment is a multi-level one, in which medium - altitude fixed wing optical imaging is used for an initial site assessment. This assessment is followed with low altitude manned helicopter based magnetometry. Subsequent to this wide area assessment targeted surface investigations are performed using either towed geophysical sensor arrays or man portable sensors. In order to be an effective tool for small UXO detection, the sensing altitude for magnetic site investigations needs to be on the order of 1 to 3 meters. These altitude requirements mean that manned helicopter surveys will generally only be feasible in large, open and relatively flat terrains. While such surveys are effective in mapping large areas relatively fast there are substantial mobilization/demobilization, staffing and equipment costs associated with these surveys, resulting in costs of approximately $100-$150/acre. In addition, due to the low altitude there are substantial risks to pilots and equipment. Surface towed arrays provide highresolution maps but have other limitations, e.g. in their ability to navigate rough terrain effectively. Thus there is a need for other systems, which can be used for effective data collection. An Unmanned Aerial Vehicle (UAV) magnetometer platform is an obvious alternative. The motivation behind such a system is that it reduces risk to operators, is lower in initial and Operational and Maintenance (O&M) costs (and can thus potentially be applied to smaller sites) and has the potential of being more effective in terms of detection and possibly characterization (through the use of dynamic acquisition, i.e. survey mission in-flight reprioritization).

LACIO: A New Collective I/O Strategy for Parallel I/O Systems  

Science Conference Proceedings (OSTI)

Parallel applications benefit considerably from the rapid advance of processor architectures and the available massive computational capability, but their performance suffers from large latency of I/O accesses. The poor I/O performance has been attributed as a critical cause of the low sustained performance of parallel systems. Collective I/O is widely considered a critical solution that exploits the correlation among I/O accesses from multiple processes of a parallel application and optimizes the I/O performance. However, the conventional collective I/O strategy makes the optimization decision based on the logical file layout to avoid multiple file system calls and does not take the physical data layout into consideration. On the other hand, the physical data layout in fact decides the actual I/O access locality and concurrency. In this study, we propose a new collective I/O strategy that is aware of the underlying physical data layout. We confirm that the new Layout-Aware Collective I/O (LACIO) improves the performance of current parallel I/O systems effectively with the help of noncontiguous file system calls. It holds promise in improving the I/O performance for parallel systems.

Electric top drives gain wide industry acceptance  

Science Conference Proceedings (OSTI)

Since its introduction, the top drive drilling system has gained acceptance as a productive and safe method for drilling oil and gas wells. Originally, the system was used mostly for offshore and higher cost land drilling, and it had to be installed as a permanent installation because of its enormous weight and size. Essentially, a top drive replaces the kelly and rotary table as the means of rotating drillpipe on oil, gas and geothermal rigs and is considered to be 15% to 40% more efficient than a kelly drive. Top drive systems allow the operator to drill and maintain directional orientation for triple stands and provide tripping efficiency because of the ability to ream and circulate with triple stands, to reduce the risk of stuck pipe or lost wells, and to improve well control and pipe handling safety. The paper describes electric top drives with DC motors, top drives with AC motors, top drives with permanent magnet motors, and top drives with permanent magnet brushless synchronous motors.

Profit-Aware Server Allocation for Green Internet Services  

E-Print Network (OSTI)

A server farm is examined, where a number of servers are used to offer a service to impatient customers. Every completed request generates a certain amount of profit, running servers consume electricity for power and cooling, while waiting customers might leave the system before receiving service if they experience excessive delays. A dynamic allocation policy aiming at satisfying the conflicting goals of maximizing the quality of users' experience while minimizing the cost for the provider is introduced and evaluated. The results of several experiments are described, showing that the proposed scheme performs well under different traffic conditions.

Wide Area Wind Field Monitoring Status & Results  

DOE Green Energy (OSTI)

Volume-scanning elastic has been investigated as a means to derive 3D dynamic wind fields for characterization and monitoring of wind energy sites. An eye-safe volume-scanning lidar system was adapted for volume imaging of aerosol concentrations out to a range of 300m. Reformatting of the lidar data as dynamic volume images was successfully demonstrated. A practical method for deriving 3D wind fields from dynamic volume imagery was identified and demonstrated. However, the natural phenomenology was found to provide insufficient aerosol features for reliable wind sensing. The results of this study may be applicable to wind field measurement using injected aerosol tracers.

Affordable Digital Planetariums with WorldWide Telescope  

E-Print Network (OSTI)

Digital planetariums can provide a broader range of educational experiences than the more classical planetariums that use star-balls. This is because of their ability to project images, content from current research and the 3D distribution of the stars and galaxies. While there are hundreds of planetariums in the country the reason that few of these are full digital is the cost. In collaboration with Microsoft Research (MSR) we have developed a way to digitize existing planetariums for approximately \\$40,000 using software freely available. We describe here how off the shelf equipment, together with MSR's WorldWide Telescope client can provide a rich and truly interactive experience. This will enable students and the public to pan though multi-wavelength full-sky scientific data sets, explore 3d visualizations of our Solar System (including trajectories of millions of minor planets), near-by stars, and the SDSS galaxy catalog.

The University of Hawaii Wide Field Imager (UHWFI)  

E-Print Network (OSTI)

The University of Hawaii Wide-Field Imager (UHWFI) is a focal compressor system designed to project the full half-degree field of the UH 2.2 m telescope onto the refurbished UH 8Kx8K CCD camera. The optics use Ohara glasses and are mounted in an oil-filled cell to minimize light losses and ghost images from the large number of internal lens surfaces. The UHWFI is equipped with a six-position filter wheel and a rotating sector blade shutter,both driven by stepper motors. The instrument saw first light in 2004 in an engineering mode. After filling the lens cell with index matching oil, integration of all software components into the user interface, tuning of the CCD performance, and the purchase of the final filter set, UHWFI is now fully commissioned at the UH 2.2 m telescope.

G.: Developing energy-aware strategies for the blackfin processor  

E-Print Network (OSTI)

Energy usage is becoming an increasingly important design constraint for all computer systems. This issue is particularly critical in battery powered, embedded designs. Although many embedded processors have developed sophisticated power management schemes, few have produced an accurate, easy-to-use energy estimation framework. In this presentation we will describe the development of an instruction-level energy modeling framework for the Analog Devices Blackfin family of processors. Using this model, we are able to accurately estimate the energy consumed when running this code. While our main goal is to demonstrate that we can perform accurate energy estimation, we also plan to develop a framework that is fully integrated with compilation in order to produce more energy-efficient binaries. In this abstract we briefly describe our methodology and show data that illustrate some of the difficulties encountered when attempting to statically model energy. 1
