Tandem Differential Mobility Analyzer/Aerodynamic Particle Sizer (APS) Handbook  

SciTech Connect

The tandem differential mobility analyzer (TDMA) is a single instrument that cycles through a series of complementary measurements of the physical properties of size-resolved submicron particles. In 2008, the TDMA was augmented through the addition of an aerodynamic particle sizer (APS), which extends the upper limit of the measured size distribution into the supermicron range. These two instruments are operated in parallel, but because they are controlled by a common computer and because the size distributions measured by the two are integrated in the produced datastreams, they are described together here. Throughout the day, the TDMA sequentially measures submicron aerosol size distributions and size-resolved hygroscopic growth distributions. More specifically, the instrument is operated as a scanning DMA to measure size distributions and as a TDMA to measure size-resolved hygroscopicity. A typical measurement sequence requires roughly 45 minutes. Each morning additional measurements are made of the relative humidity (RH) dependent hygroscopicity and temperature-dependent volatility of size-resolved particles. When the outside temperature and RH are within acceptable ranges, the hydration state of size-resolved particles is also characterized. The measured aerosol distributions complement the array of aerosol instruments in the Aerosol Observing System (AOS) and provide additional details of the light-scattering and cloud-nucleating characteristics of the aerosol.

A cost-effective differential mobility analyzer (cDMA) for multiple DMA column applications  

Science Conference Proceedings (OSTI)

In aerosol research and applications, a differential mobility analyzer (DMA) is now considered the standard tool for sizing and classifying monodisperse particles in the sub-micrometer and nanometer size ranges. However, DMA application at the pilot or industrial production scale remains infeasible because of the low mass throughput. A simple way to scale up DMA operation is to use multiple DMA columns. The manufacture and maintenance costs of existing DMAs, however, limit such a scale-up. A cost-effective DMA column (named cDMA) has thus been developed in this work to address the above issue. To reduce its manufacturing cost, the prototype was constructed using parts requiring little machining. The cDMA column was also designed for easy maintenance and easy variation of the classification length for any application-specified size range. In this study, prototypes with two particle classification lengths, 1.75 and 4.50 cm, were constructed and their performance was experimentally evaluated at sheath-to-aerosol flowrate ratios of 5:1, 10:1, and 15:1 via the tandem DMA (TDMA) technique. It was concluded that both prototype cDMAs, operated at a sheath/aerosol flowrate ratio less than 15:1 and with a polydisperse aerosol flowrate of 1.0 lpm, achieved sizing resolution comparable to that offered by Nano-DMA. The longer cDMA had comparable transmission efficiency to that of Nano-DMA, and the shorter cDMA exceeded the performance of Nano-DMA. Hence, the cDMA with the shorter (1.75 cm) classification length is better suited for the characterization of macromolecular samples.

High-Resolution Differential Ion Mobility Separations Using Planar Analyzers at Elevated Dispersion Fields  

SciTech Connect

Analyses of complex or isomeric mixtures increasingly involve ion mobility spectrometry/ mass spectrometry (IMS/MS). The IMS methods are grouped into conventional, based on the absolute ion mobility, and differential or field asymmetric waveform IMS (FAIMS), based on the mobility difference in strong and weak electric fields. The key attraction of FAIMS is substantial orthogonality to MS, and several FAIMS/MS platforms have been commercialized. However, the utility of FAIMS had been constrained by limited resolving power, typically R ~ 10 - 20. Recently, the use of helium/nitrogen mixtures comprising up to 75% He has enabled R > 100, with broad resolution gains allowing separation of previously “co-eluting” isomers. These performance metrics open major new FAIMS applications in proteomic and other biological analyses. Here, we show that raising the separation field by ~35% over the previous 21 kV/cm provides similar or better resolution at 50% He, while avoiding problems due to elevated gas pressure in the MS manifold upon excessive He intake. In particular, a resolving power of >200 has been achieved for multiply-charged peptides. The field heating of ions under these conditions appears to exceed that at higher He content but weaker separation field, inducing greater izomerization of fragile species.

Selection and generation of waveforms for differential mobility spectrometry  

Science Conference Proceedings (OSTI)

Devices based on differential mobility spectrometry (DMS) are used in a number of ways, including applications as ion prefilters for API-MS systems, as detectors or selectors in hybrid instruments (GC-DMS, DMS-IMS), and in standalone systems for chemical detection and identification. DMS ion separation is based on the relative difference between high field and low field ion mobility known as the alpha dependence, and requires the application of an intense asymmetric electric field known as the DMS separation field, typically in the megahertz frequency range. DMS performance depends on the waveform and on the magnitude of this separation field. In this paper, we analyze the relationship between separation waveform and DMS resolution and consider feasible separation field generators. We examine ideal and practical DMS separation field waveforms and discuss separation field generator circuit types and their implementations. To facilitate optimization of the generator designs, we present a set of relations that connect ion alpha dependence to DMS separation fields. Using these relationships we evaluate the DMS separation power of common generator types as a function of their waveform parameters. Optimal waveforms for the major types of DMS separation generators are determined for ions with various alpha dependences. These calculations are validated by comparison with experimental data.

Accelerated High-Resolution Differential Ion Mobility Separations Using Hydrogen  

SciTech Connect

The resolving power of differential ion mobility spectrometry (FAIMS) was dramatically increased recently by the introduction of carrier gases comprising up to 75% He or various vapors, enabling many new applications. However, the gains were often at the expense of analysis speed, in particular making high-resolution FAIMS incompatible with online liquid-phase separations. Here, we report FAIMS employing hydrogen, specifically in mixtures with N2 containing up to 98.4% H2. Such compositions raise the mobilities of all ions and thus resolving power, while avoiding the electrical breakdown inevitable in He-rich mixtures. The increases of resolving power and ensuing peak resolution are especially significant at the greatest H2 fractions - above {approx}80 - 90%. Higher resolution can be exchanged for acceleration of the analyses by up to {approx}20 times. For more mobile species such as multiply-charged peptides, this exchange is presently forced by the constraints of existing FAIMS devices, but future designs optimized for H2 should consistently improve resolution for all analytes.

High-Resolution Differential Ion Mobility Spectrometry of a Protein  

SciTech Connect

Use of elevated electric fields and helium-rich gases has recently enabled differential IMS with resolving power up to R ~ 300. Here we applied that technique to proteins (namely, mass-selected ubiquitin ions), achieving R up to ~80 and separating many previously mixed conformers. While still limited by conformational multiplicity within each observed feature, this resolution is some four times the highest previously reported using either conventional or differential IMS. The capability for fine resolution of protein conformers may open new avenues for variant separation in top-down proteomics.

Differential Mobility Spectrometry/Mass Spectrometry: The Design of a New Mass Spectrometer for Real-Time Chemical Analysis in the Field  

SciTech Connect

The design of a prototype, field-portable mass spectrometer (MS) is described. The MS has been designed with an atmospheric interface in order to couple the system to a commercially available differential mobility spectrometer. The differential mobility spectrometer provides selective injection of trace-level analytes of interest into the inlet of the MS for real-time chemical detection. To accomplish this task, the MS design incorporates the use of an electrodynamic ion funnel to transport the ion beam, generated at atmospheric pressure, to the high-vacuum chamber that houses the mass analyzer. This leads to a design that utilizes two stages of differential pumping to achieve an overall pressure drop from atmosphere (760 Torr) to approximately 1 ×

High-Definition Differential Ion Mobility Spectrometry with Resolving Power up to 500  

Science Conference Proceedings (OSTI)

As the resolution of analytical methods improve, further progress tends to be increasingly limited by instrumental parameter instabilities that could be ignored before. This is now the case with differential ion mobility spectrometry (FAIMS), where fluctuations of the voltages and gas pressure have become critical. A new high-definition generator for FAIMS compensation voltage reported here provides a stable and accurate output than can be scanned with negligible steps. This reduces the spectral drift and peak width, thus improving the resolving power (R) and resolution. The gain for multiply-charged peptides that have narrowest peaks is up to ~40%, and R ~ 400 - 500 is achievable using He/N2 or H2/N2 gas mixtures.

Separation of Protein Conformers by Differential Ion Mobility in Hydrogen-Rich Gases  

Science Conference Proceedings (OSTI)

Proteins in solution or the gas phase tend to exhibit multiple conformational families, each comprising distinct structures. Separation methods have generally failed to resolve these, with their convolution producing wide peaks. Here we report full separation of >10 conformers for most ubiquitin charge states by the new approach of differential ion mobility spectrometry (FAIMS) employing H2/N2 gas mixtures with up to 85% H2. The resolving power (up to 400) is five times the highest previously achieved (using He/N2 buffers), greatly increasing the separation specificity. The peak widths match the narrowest obtained by FAIMS for any species under same conditions and scale with the protein charge state (z) and ion residence time (t) as z?1/2 and t?1/2, as prescribed for instrumental (diffusional) broadening. This suggests resolution of specific geometries rather than broader ensembles.

Differential cross section and analyzing power of the p-vectorp{yields}pp{pi}{sup 0} reaction at a beam energy of 390 MeV  

Science Conference Proceedings (OSTI)

The differential cross section and analyzing power A{sub y} of the p-vectorp{yields}pp{pi}{sup 0} reaction have been measured at RCNP in coplanar geometry at a beam energy of 390 MeV and the dependence on both the pion emission angle and the relative momentum of the final protons has been extracted. The angular variation of A{sub y} for the large values of the relative momentum studied here shows that this is primarily an effect of the interference of pion s and p waves and this interference can also explain the momentum dependence. Within the framework of a very simple model, these results would suggest that the pion-production operator has a significant long-range component.

The design and design philosophy of a high performance, extremely versatile transient analyzer is described. This sub-system was designed to be controlled through the data acquisition computer system which allows hands off operation. Thus it may be placed on the experiment side of the high voltage safety break between the experimental device and the control room. This analyzer provides control features which are extremely useful for data acquisition from PPPL diagnostics. These include dynamic sample rate changing, which may be intermixed with multiple post trigger operations with variable length blocks using normal, peak to peak or integrate modes. Included in the discussion are general remarks on the advantages of adding intelligence to transient analyzers, a detailed description of the characteristics of the PPPL transient analyzer, a description of the hardware, firmware, control language and operation of the PPPL transient analyzer, and general remarks on future trends in this type of instrumentation both at PPPL and in general.

Combinatorial mobile IP: a new efficient mobility management using minimized paging and local registration  

E-Print Network (OSTI)

Abstract. Combinatorial Mobile IP, a new mobility management scheme for Mobile IP, is proposed and analyzed. We present how to adopt mobility management schemes on cellular networks and adapt them in Mobile IP without disrupting the nature of the Internet. We apply widely used mobility management schemes such as hierarchical architecture and paging in cellular networks to Mobile IP. We restrict paging to the area that has to be paged using local registrations. In this way, we show that the total signaling costs of Combinatorial Mobile IP are reduced compared to other micro-mobility protocols such as Mobile IP Regional Registration and P-MIP. Random walk on a connected graph is used to analyze the performance of Combinatorial Mobile IP.

A pulse-height analyzer system of improved design for sorting and counting a series of pulses, such as provided by a scintillation detector in nuclear radiation measurements, is described. The analyzer comprises a main transmission line, a cathode-ray tube for each section of the line with its deflection plates acting as the line capacitance; means to bias the respective cathode ray tubes so that the beam strikes a target only when a prearranged pulse amplitude is applied, with each tube progressively biased to respond to smaller amplitudes; pulse generating and counting means associated with each tube to respond when the beam is deflected; a control transmission line having the same time constant as the first line per section with pulse generating means for each tube for initiating a pulse on the second transmission line when a pulse triggers the tube of corresponding amplitude response, the former pulse acting to prevent successive tubes from responding to the pulse under test. This arrangement permits greater deflection sensitivity in the cathode ray tube and overcomes many of the disadvantages of prior art pulse-height analyzer circuits.

A linear or rectangular array of capillaries is introduced into a rectangular flow chamber. Sheath fluid draws individual sample streams through the cuvette. The capillaries are closely and evenly spaced and held by a transparent retainer in a fixed position in relation to an optical detection system. Collimated sample excitation radiation is applied simultaneously across the ends of the capillaries in the retainer. Light emitted from the excited sample is detected by the optical detection system. The retainer is provided by a transparent chamber having inward slanting end walls. The capillaries are wedged into the chamber. One sideways dimension of the chamber is equal to the diameter of the capillaries and one end to end dimension varies from, at the top of the chamber, slightly greater than the sum of the diameters of the capillaries to, at the bottom of the chamber, slightly smaller than the sum of the diameters of the capillaries. The optical system utilizes optic fibers to deliver light to individual photodetectors, one for each capillary tube. A filter or wavelength division demultiplexer may be used for isolating fluorescence at particular bands. 21 figs.

Downhole Fluid Analyzer Development  

SciTech Connect

A novel fiber optic downhole fluid analyzer has been developed for operation in production wells. This device will allow real-time determination of the oil, gas and water fractions of fluids from different zones in a multizone or multilateral completion environment. The device uses near infrared spectroscopy and induced fluorescence measurement to unambiguously determine the oil, water and gas concentrations at all but the highest water cuts. The only downhole components of the system are the fiber optic cable and windows. All of the active components--light sources, sensors, detection electronics and software--will be located at the surface, and will be able to operate multiple downhole probes. Laboratory testing has demonstrated that the sensor can accurately determine oil, water and gas fractions with a less than 5 percent standard error. Once installed in an intelligent completion, this sensor will give the operating company timely information about the fluids arising from various zones or multilaterals in a complex completion pattern, allowing informed decisions to be made on controlling production. The research and development tasks are discussed along with a market analysis.

PULSE HEIGHT ANALYZER  

DOE Patents (OSTI)

An anticoincidence device is described for a pair of adjacent channels of a multi-channel pulse height analyzer for preventing the lower channel from generating a count pulse in response to an input pulse when the input pulse has sufficient magnitude to reach the upper level channel. The anticoincidence circuit comprises a window amplifier, upper and lower level discriminators, and a biased-off amplifier. The output of the window amplifier is coupled to the inputs of the discriminators, the output of the upper level discriminator is connected to the resistance end of a series R-C network, the output of the lower level discriminator is coupled to the capacitance end of the R-C network, and the grid of the biased-off amplifier is coupled to the junction of the R-C network. In operation each discriminator produces a negative pulse output when the input pulse traverses its voltage setting. As a result of the connections to the R-C network, a trigger pulse will be sent to the biased-off amplifier when the incoming pulse level is sufficient to trigger only the lower level discriminator.

Electrical Mobility Spectrometer Using a Diethylene Glycol Condensation Particle Counter for Measurement of Aerosol Size Distributions Down to 1 nm  

Science Conference Proceedings (OSTI)

We report a new scanning mobility particle spectrometer (SMPS) for measuring number size distributions of particles down to {approx}1 nm mobility diameter. This SMPS includes an aerosol charger, a TSI 3085 nano differential mobility analyzer (nanoDMA), an ultrafine condensation particle counter (UCPC) using diethylene glycol (DEG) as the working fluid, and a conventional butanol CPC (the 'booster') to detect the small droplets leaving the DEG UCPC. The response of the DEG UCPC to negatively charged sodium chloride particles with mobility diameters ranging from 1-6 nm was measured. The sensitivity of the DEG UCPC to particle composition was also studied by comparing its response to positively charged 1.47 and 1.70 nm tetra-alkyl ammonium ions, sodium chloride, and silver particles. A high resolution differential mobility analyzer was used to generate the test particles. These results show that the response of this UCPC to sub-2 nm particles is sensitive to particle composition. The applicability of the new SMPS for atmospheric measurement was demonstrated during the Nucleation and Cloud Condensation Nuclei (NCCN) field campaign (Atlanta, Georgia, summer 2009). We operated the instrument at saturator and condenser temperatures that allowed the efficient detection of sodium chloride particles but not of air ions having the same mobility. We found that particles as small as 1 nm were detected during nucleation events but not at other times. Factors affecting size distribution measurements, including aerosol charging in the 1-10 nm size range, are discussed. For the charger used in this study, bipolar charging was found to be more effective for sub-2 nm particles than unipolar charging. No ion induced nucleation inside the charger was observed during the NCCN campaign.

Sketch Recognition on Mobile Devices  

E-Print Network (OSTI)

Sketch recognition allows computers to understand and model hand drawn sketches and diagrams. Traditionally sketch recognition systems required a pen based PC interface, but powerful mobile devices such as tablets and smartphones can provide a new platform for sketch recognition systems. We describe a new sketch recognition library, Strontium (SrL) that combines several existing sketch recognition libraries modified to run on both personal computers and on the Android platform. We analyzed the recognition speed and accuracy implications of performing low-level shape recognition on smartphones with touch screens. We found that there is a large gap in recognition speed on mobile devices between recognizing simple shapes and more complex ones, suggesting that mobile sketch interface designers limit the complexity of their sketch domains. We also found that a low sampling rate on mobile devices can affect recognition accuracy of complex and curved shapes. Despite this, we found no evidence to suggest that using a finger as an input implement leads to a decrease in simple shape recognition accuracy. These results show that the same geometric shape recognizers developed for pen applications can be used in mobile applications, provided that developers keep shape domains simple and ensure that input sampling rate is kept as high as possible.

A continuation of this kind of user support is being done by our upcoming workshop to help past users reduce and analyze data from our SANS instruments using the established data acquisition software. We will be using Igor Pro and our in house routines to do the data reduction and fitting. The goal is that everyone who attends will leave the workshop with completely analyzed data and meaningful results. To accomplish this feat, we will focus the first day on data reduction and the following two days on analysis. We will go over in detail all the different fitting functions that are currently supported in Igor and set-aside time to discuss what other functions need to be inputted into Igor. Finally, there will be a demonstration of the new NSSD data reduction/analysis software, MANTID, that will be implemented in the near future across the SANS beam lines.

MULTICHANNEL PULSE-HEIGHT ANALYZER  

DOE Patents (OSTI)

This patent deals with electronic computing circuits and more particularly to pulse-height analyzers used for classifying variable amplitude pulses into groups of different amplitudes. The device accomplishes this pulse allocation by by converting the pulses into frequencies corresponding to the amplitudes of the pulses, which frequencies are filtered in channels individually pretuned to a particular frequency and then detected and recorded in the responsive channel. This circuit substantially overcomes the disadvantages of prior annlyzers incorporating discriminators pre-set to respond to certain voltage levels, since small variation in component values is not as critical to satisfactory circuit operation.

Mobile Energy Laboratory Procedures  

SciTech Connect

Pacific Northwest Laboratory (PNL) has been tasked to plan and implement a framework for measuring and analyzing the efficiency of on-site energy conversion, distribution, and end-use application on federal facilities as part of its overall technical support to the US Department of Energy (DOE) Federal Energy Management Program (FEMP). The Mobile Energy Laboratory (MEL) Procedures establish guidelines for specific activities performed by PNL staff. PNL provided sophisticated energy monitoring, auditing, and analysis equipment for on-site evaluation of energy use efficiency. Specially trained engineers and technicians were provided to conduct tests in a safe and efficient manner with the assistance of host facility staff and contractors. Reports were produced to describe test procedures, results, and suggested courses of action. These reports may be used to justify changes in operating procedures, maintenance efforts, system designs, or energy-using equipment. The MEL capabilities can subsequently be used to assess the results of energy conservation projects. These procedures recognize the need for centralized NM administration, test procedure development, operator training, and technical oversight. This need is evidenced by increasing requests fbr MEL use and the economies available by having trained, full-time MEL operators and near continuous MEL operation. DOE will assign new equipment and upgrade existing equipment as new capabilities are developed. The equipment and trained technicians will be made available to federal agencies that provide funding for the direct costs associated with MEL use.

Microchip and wedge ion funnels and planar ion beam analyzers using same  

DOE Patents (OSTI)

Electrodynamic ion funnels confine, guide, or focus ions in gases using the Dehmelt potential of oscillatory electric field. New funnel designs operating at or close to atmospheric gas pressure are described. Effective ion focusing at such pressures is enabled by fields of extreme amplitude and frequency, allowed in microscopic gaps that have much higher electrical breakdown thresholds in any gas than the macroscopic gaps of present funnels. The new microscopic-gap funnels are useful for interfacing atmospheric-pressure ionization sources to mass spectrometry (MS) and ion mobility separation (IMS) stages including differential IMS or FAIMS, as well as IMS and MS stages in various configurations. In particular, "wedge" funnels comprising two planar surfaces positioned at an angle and wedge funnel traps derived therefrom can compress ion beams in one dimension, producing narrow belt-shaped beams and laterally elongated cuboid packets. This beam profile reduces the ion density and thus space-charge effects, mitigating the adverse impact thereof on the resolving power, measurement accuracy, and dynamic range of MS and IMS analyzers, while a greater overlap with coplanar light or particle beams can benefit spectroscopic methods.

Mobile trough genesis over the Mongolian Plateau  

E-Print Network (OSTI)

The purpose of this study is to understand the mechanisms responsible for formation of mobile troughs over the large source region in Mongolia. Three winter season mobile troughs which intensified rapidly after formation were analyzed. An objective method developed by Lefevre and Nielsen-Gammon (1995) was used to track the mobile troughs-a quasigeostrophic potential vorticity (QGPV) and associated piecewise tendency diagnosis (PTD) technique developed by Lefevre (1995) was used to analyze the formation mechanisms. Through the PTD technique, which involves in the inversion of QGPV and QGPV advection, it was determined that the mobile troughs developed from a combination of deformation / superposition and downstream development. Baroclinic processes were not evident near the time of formation, but were important as the troughs moved over the Sea of Japan. Two troughs interacted with surface cyclones, but in both cases only minor development occurred. As the troughs moved underneath a climatological mean long wave trough, all three troughs weakened from deformation. There was evidence of orographic masking in one of the cases as the mobile trough existed at upper-levels (above 500 mb) prior to formation by the objective method. However, as the trough moved to the lee-side of the Altai-Sayan mountains, the trough lowered to 500 mb and was initialized by the objective method.

Analyzing video compression for transporting over wireless fading channels  

E-Print Network (OSTI)

Wireless video communication is becoming increasingly popular these days with new applications such as TV on mobile and video phones. Commercial success of these applications requires superior video quality at the receiver. So it is imperative to analyze the effect of a wireless channel on a video transmission. The aim of this research is to analyze the video transmission over Rayleigh fading channels for various bit error rates (BER), signal to noise ratios (Eb/N0) and Doppler rates, and to suggest which source coding scheme is best at which BER, Eb/N0 and Doppler rates. Alternative schemes such as hybrid (digital/analog) schemes were considered and their performances were compared with pure digital communication. It is also shown that the combination of digital and analog video communication does not yield any better performance compared to pure digital video communication.

Power Analyzer Power Analyzer Power Analyzer power analyzer Gonio-photometer | Integrating sphere | Power analyzer | Spectro-radiometer A power analyzer is a very necessary tool for lighting research. With the power analyzer we are able to monitor the input voltage to the lamp as well as the input power and current. The amount of power a lamp or a lamp-ballast combination uses is very important when determining its efficiency. It is also important to monitor the input voltage to make sure it doesn't vary. This can affect the light output of a lamp greatly. With the power analyzer we can also measure things like the power factor, harmonic distortion, and current crest factor of some lamps. These measurements tell us how well a lamp is working. For example, a high power

Mobile systems capability plan  

Science Conference Proceedings (OSTI)

This plan was prepared to initiate contracting for and deployment of these mobile system services. 102,000 cubic meters of retrievable, contact-handled TRU waste are stored at many sites around the country. Also, an estimated 38,000 cubic meters of TRU waste will be generated in the course of waste inventory workoff and continuing DOE operations. All the defense TRU waste is destined for disposal in WIPP near Carlsbad NM. To ship TRU waste there, sites must first certify that the waste meets WIPP waste acceptance criteria. The waste must be characterized, and if not acceptable, subjected to additional processing, including repackaging. Most sites plan to use existing fixed facilities or open new ones between FY1997-2006 to perform these functions; small-quantity sites lack this capability. An alternative to fixed facilities is the use of mobile systems mounted in trailers or skids, and transported to sites. Mobile systems will be used for all characterization and certification at small sites; large sites can also use them. The Carlsbad Area Office plans to pursue a strategy of privatization of mobile system services, since this offers a number of advantages. To indicate the possible magnitude of the costs of deploying mobile systems, preliminary estimates of equipment, maintenance, and operating costs over a 10-year period were prepared and options for purchase, lease, and privatization through fixed-price contracts considered.

Data-driven Co-clustering Model of Internet Usage in Large Mobile Societies  

E-Print Network (OSTI)

Design and simulation of future mobile networks will center around human interests and behavior. We propose a design paradigm for mobile networks driven by realistic models of users' on-line behavior, based on mining of billions of wireless-LAN records. We introduce a systematic method for large-scale multi-dimensional coclustering of web activity for thousands of mobile users at 79 locations. We find surprisingly that users can be consistently modeled using ten clusters with disjoint profiles. Access patterns from multiple locations show differential user behavior. This is the first study to obtain such detailed results for mobile Internet usage.

Improved Security Mechanism for Mobile IPv6  

E-Print Network (OSTI)

Security is a critical design issue in Mobile IPv6 since adversaries can take advantage of its routing process and arbitrarily channelize the traffic to different destinations. The original security scheme, the return routability (RR) procedure, used in Mobile IPv6 route optimization does not protect against adversaries who are on the path between the home agent (HA) and the correspondent node (CN) [11]. In addition, the long latency associated with the return routability test can impact delay-sensitive applications. This paper presents a hash chain based security mechanism to improve the security and performance of the return routability procedure in Mobile IPv6. Our fast authentication mechanism utilizes the hash chain element as an extra certificate to the mobile node in authenticating binding updates while running the routing process. In addition, by removing the necessity of the home test procedure in the RR test our mechanism can reduce the binding update latency. We analyze the security strength of our scheme under different adversary scenarios. Furthermore, a performance comparison of our scheme and the original RR procedure is provided

Mobile Biomass Pelletizing System  

DOE Green Energy (OSTI)

This grant project examines multiple aspects of the pelletizing process to determine the feasibility of pelletizing biomass using a mobile form factor system. These aspects are: the automatic adjustment of the die height in a rotary-style pellet mill, the construction of the die head to allow the use of ceramic materials for extreme wear, integrating a heat exchanger network into the entire process from drying to cooling, the use of superheated steam for adjusting the moisture content to optimum, the economics of using diesel power to operate the system; a break-even analysis of estimated fixed operating costs vs. tons per hour capacity. Initial development work has created a viable mechanical model. The overall analysis of this model suggests that pelletizing can be economically done using a mobile platform.

Efficient Collaborative Application Monitoring Scheme for Mobile Networks  

E-Print Network (OSTI)

New operating systems for mobile devices allow their users to download millions of applications created by various individual programmers, some of which may be malicious or flawed. In order to detect that an application is malicious, monitoring its operation in a real environment for a significant period of time is often required. Mobile devices have limited computation and power resources and thus are limited in their monitoring capabilities. In this paper we propose an efficient collaborative monitoring scheme that harnesses the collective resources of many mobile devices, "vaccinating" them against potentially unsafe applications. We suggest a new local information flooding algorithm called "TTL Probabilistic Propagation" (TPP). The algorithm periodically monitors one or more application and reports its conclusions to a small number of other mobile devices, who then propagate this information onwards. The algorithm is analyzed, and is shown to outperform existing state of the art information propagation al...

We ran a global social mobilization contest and recorded personal traits of the participants and those they mobilized. We examined how those traits influenced the speed of mobilization. Individuals mobilized faster when they heard about the contest directly from the contest organization, and decreased in speed when hearing from less personal source types (e.g. family vs. media).

Mobile Window Thermal Test  

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

Mobile Window Thermal Test (MoWiTT) Facility Mobile Window Thermal Test (MoWiTT) Facility winter.jpg (469135 bytes) The window has come a long way since the days when it was a single pane of glass in a wood frame. Low-emissivity windows were designed to help buildings retain some of the energy that would have leaked out of less efficient windows. Designing efficient window-and-frame systems is one strategy for reducing the energy use of buildings. But the net energy flowing through a window is a combination of temperature- driven thermal flows and transmission of incident solar energy, both of which vary with time. U-factor and solar heat gain coefficient (SHGC), the window properties that control these flows, depend partly on ambient conditions. Window energy flows can affect how much energy a building uses, depending on when the window flows are available to help meet other energy demands within the building, and when they are adverse, adding to building energy use. This leads to a second strategy for reducing building energy use: using the beneficial solar gain available through a window, either for winter heating or for daylighting, while minimizing adverse flows.

Improved Quantitative Analysis of Ion Mobility Spectrometry by Chemometric Multivariate Calibration  

Science Conference Proceedings (OSTI)

Traditional peak-area calibration and the multivariate calibration methods of principle component regression (PCR) and partial least squares (PLS), including unfolded PLS (U-PLS) and multi-way PLS (N-PLS), were evaluated for the quantification of 2,4,6-trinitrotoluene (TNT) and cyclo-1,3,5-trimethylene-2,4,6-trinitramine (RDX) in Composition B samples analyzed by temperature step desorption ion mobility spectrometry (TSD-IMS). The true TNT and RDX concentrations of eight Composition B samples were determined by high performance liquid chromatography with UV absorbance detection. Most of the Composition B samples were found to have distinct TNT and RDX concentrations. Applying PCR and PLS on the exact same IMS spectra used for the peak-area study improved quantitative accuracy and precision approximately 3 to 5 fold and 2 to 4 fold, respectively. This in turn improved the probability of correctly identifying Composition B samples based upon the estimated RDX and TNT concentrations from 11% with peak area to 44% and 89% with PLS. This improvement increases the potential of obtaining forensic information from IMS analyzers by providing some ability to differentiate or match Composition B samples based on their TNT and RDX concentrations.

Detecting energy-greedy anomalies and mobile malware variants  

E-Print Network (OSTI)

Mobile users of computation and communication services have been rapidly adopting battery-powered mobile handhelds, such as PocketPCs and SmartPhones, for their work. However, the limited battery-lifetime of these devices restricts their portability and applicability, and this weakness can be exacerbated by mobile malware targeting depletion of battery energy. Such malware are usually difficult to detect and prevent, and frequent outbreaks of new malware variants also reduce the effectiveness of commonlyseen signature-based detection. To alleviate these problems, we propose a power-aware malware-detection framework that monitors, detects, and analyzes previously unknown energy-depletion threats. The framework is composed of (1) a power monitor which collects power samples and builds a power consumption history from the collected samples, and (2) a data analyzer which generates a power signature from the constructed history. To generate a power signature, simple and effective noise-filtering and data-compression are applied, thus reducing the detection overhead. Similarities between power signatures are measured by the ? 2-distance, reducing both false-positive and false-negative detection rates. According to our experimental results on an HP iPAQ running a Windows Mobile OS, the proposed framework achieves significant (up to 95%) storage-savings without losing the detection accuracy, and a 99 % true-positive rate in classifying mobile malware.

NON-DESTRUCTIVE SOIL CARBON ANALYZER.  

Science Conference Proceedings (OSTI)

This report describes the feasibility, calibration, and safety considerations of a non-destructive, in situ, quantitative, volumetric soil carbon analytical method based on inelastic neutron scattering (INS). The method can quantify values as low as 0.018 gC/cc, or about 1.2% carbon by weight with high precision under the instrument's configuration and operating conditions reported here. INS is safe and easy to use, residual soil activation declines to background values in under an hour, and no radiological requirements are needed for transporting the instrument. The labor required to obtain soil-carbon data is about 10-fold less than with other methods, and the instrument offers a nearly instantaneous rate of output of carbon-content values. Furthermore, it has the potential to quantify other elements, particularly nitrogen. New instrumentation was developed in response to a research solicitation from the U.S. Department of Energy (DOE LAB 00-09 Carbon Sequestration Research Program) supporting the Terrestrial Carbon Processes (TCP) program of the Office of Science, Biological and Environmental Research (BER). The solicitation called for developing and demonstrating novel techniques for quantitatively measuring changes in soil carbon. The report includes raw data and analyses of a set of proof-of-concept, double-blind studies to evaluate the INS approach in the first phase of developing the instrument. Managing soils so that they sequester massive amounts of carbon was suggested as a means to mitigate the atmospheric buildup of anthropogenic CO{sub 2}. Quantifying changes in the soils' carbon stocks will be essential to evaluating such schemes and documenting their performance. Current methods for quantifying carbon in soil by excavation and core sampling are invasive, slow, labor-intensive and locally destroy the system being observed. Newly emerging technologies, such as Laser Induced Breakdown Spectroscopy and Near-Infrared Spectroscopy, offer soil-carbon analysis; however, these also are invasive and destructive techniques. The INS approach permits quantification in a relatively large volume of soil without disrupting the measurement site. The technique is very fast and provides nearly instantaneous results thereby reducing the cost, and speeding up the rate of analysis. It also has the potential to cover large areas in a mobile scanning mode. These capabilities will significantly advance the tracking carbon sequestration and offer a tool for research in agronomy, forestry, soil ecology and biogeochemistry.

Computer modeling of ORNL storage tank sludge mobilization and mixing  

SciTech Connect

This report presents and analyzes the results of the computer modeling of mixing and mobilization of sludge in horizontal, cylindrical storage tanks using submerged liquid jets. The computer modeling uses the TEMPEST computational fluid dynamics computer program. The horizontal, cylindrical storage tank configuration is similar to the Melton Valley Storage Tanks (MVST) at Oak Ridge National (ORNL). The MVST tank contents exhibit non-homogeneous, non-Newtonian rheology characteristics. The eventual goals of the simulations are to determine under what conditions sludge mobilization using submerged liquid jets is feasible in tanks of this configuration, and to estimate mixing times required to approach homogeneity of the contents of the tanks.

Analyzing Options for Airborne Emergency Wireless Communications  

SciTech Connect

In the event of large-scale natural or manmade catastrophic events, access to reliable and enduring commercial communication systems is critical. Hurricane Katrina provided a recent example of the need to ensure communications during a national emergency. To ensure that communication demands are met during these critical times, Idaho National Laboratory (INL) under the guidance of United States Strategic Command has studied infrastructure issues, concerns, and vulnerabilities associated with an airborne wireless communications capability. Such a capability could provide emergency wireless communications until public/commercial nodes can be systematically restored. This report focuses on the airborne cellular restoration concept; analyzing basic infrastructure requirements; identifying related infrastructure issues, concerns, and vulnerabilities and offers recommended solutions.

Bacterial mobilization of polonium  

Science Conference Proceedings (OSTI)

Polonium has been observed as the sole {alpha}-emitting nuclide in groundwaters of central Florida, in the absence of its radiogenic parents, at levels of 1,000 dpm/1 or more. Because of the chemical similarity of Po to S (both occupy the same column in the periodic table), studies were begun to determine whether bacteria, particularly those species active in sulfur cycling, could account for the selective solubilization and mobilization of Po. Possible sources of Po are the U-rich phosphate rock and phosphogypsum (gypsum), a byproduct in the manufacture of phosphoric acid. This paper reports on a series of experiments involving the interaction of bacteria with this waste gypsum that resulted in the solubilization of Po. Bacteria were isolated from gypsum that were capable of mediating Po release in column experiments of Po. Bacteria were isolated from gypsum that were capable of mediating Po release in column experiments when fed a growth medium. Sulfate-reducing bacteria were particularly effective at mediating Po release provided the sulfide levels did not rise above 10 {mu}M, in which case Po was apparently coprecipitated as a metal sulfide. Conversely, the ability of sulfate-reducing bacteria to effectively remove dissolved Po when sulfide levels are high suggests that these bacteria may be used as an effective bioremediation tool at reducing groundwater Po levels. 22 refs., 10 figs.

Migrating Home Agents Towards Internet-scale Mobility Deployments  

E-Print Network (OSTI)

While the IETF standardization process of the Mobile IPv6 and Network Mobility (NEMO) protocols is almost complete, their large-scale deployment is not yet possible. With these technologies, in order to hide location changes of the mobile nodes from the rest of the Internet, a specific router called a home agent is used. However, this equipment generates resilience and performance issues such as protocol scalability and longer paths. In order to solve these problems, we describe and analyze a new concept called Home Agent Migration. The main feature of this solution is the distribution of home agents inside the current Internet topology to reduce distances to end-nodes. As is usually done for anycast routing, they advertise the same network prefix from different locations; moreover they also exchange information

Multiple capillary biochemical analyzer with barrier member  

DOE Patents (OSTI)

A multiple capillary biochemical analyzer for sequencing DNA and performing other analyses, in which a set of capillaries extends from wells in a microtiter plate into a cuvette. In the cuvette the capillaries are held on fixed closely spaced centers by passing through a sandwich construction having a pair of metal shims which squeeze between them a rubber gasket, forming a leak proof seal for an interior chamber in which the capillary ends are positioned. Sheath fluid enters the chamber and entrains filament sample streams from the capillaries. The filament sample streams, and sheath fluid, flow through aligned holes in a barrier member spaced close to the capillary ends, into a collection chamber having a lower glass window. The filament streams are illuminated above the barrier member by a laser, causing them to fluoresce. The fluorescence is viewed end-on by a CCD camera chip located below the glass window. The arrangement ensures an equal optical path length from all fluorescing spots to the CCD chip and also blocks scattered fluorescence illumination, providing more uniform results and an improved signal to noise ratio.

AnalyzeHOLE: An Integrated Wellbore Flow Analysis Tool  

SciTech Connect

Conventional interpretation of flow logs assumes that hydraulic conductivity is directly proportional to flow change with depth. However, well construction can significantly alter the expected relation between changes in fluid velocity and hydraulic conductivity. Strong hydraulic conductivity contrasts between lithologic intervals can be masked in continuously screened wells. Alternating intervals of screen and blank casing also can greatly complicate the relation between flow and hydraulic properties. More permeable units are not necessarily associated with rapid fluid-velocity increases. Thin, highly permeable units can be misinterpreted as thick and less permeable intervals or not identified at all. These conditions compromise standard flow-log interpretation because vertical flow fields are induced near the wellbore. AnalyzeHOLE, an integrated wellbore analysis tool for simulating flow and transport in wells and aquifer systems, provides a better alternative for simulating and evaluating complex well-aquifer system interaction. A pumping well and adjacent aquifer system are simulated with an axisymmetric, radial geometry in a two-dimensional MODFLOW model. Hydraulic conductivities are distributed by depth and estimated with PEST by minimizing squared differences between simulated and measured flows and drawdowns. Hydraulic conductivity can vary within a lithology but variance is limited with regularization. Transmissivity of the simulated system also can be constrained to estimates from single-well, pumping tests. Water-quality changes in the pumping well are simulated with simple mixing models between zones of differing water quality. These zones are differentiated by backtracking thousands of particles from the well screens with MODPATH. An Excel spreadsheet is used to interface the various components of AnalyzeHOLE by (1) creating model input files, (2) executing MODFLOW, MODPATH, PEST, and supporting FORTRAN routines, and (3) importing and graphically displaying pertinent results.

Installation and Testing of a Jorin Visual Process Analyzer  

Science Conference Proceedings (OSTI)

The Jorin Visual Process Analyzer (ViPA) is an on-line instrument that uses video microscope imaging to detect and measure the physical characteristics of dispersed objects within a process stream or laboratory sample. Object analysis is performed by capturing an on-going sequence of single frames from the video feed and relaying the images in real time to a nearby control computer where the ViPA software then processes and transfigures the information from the images into meaningful process data. The ViPA captures and analyzes approximately 15 images per second and continuously records 17 material parameters including size, shape and optical density. The ViPA software uses the measured parameters to differentiate between different classes of objects including organic droplets, gas bubbles, and solid particles. Procurement of this instrument provides a unique capability to support predictive modeling and further understanding of mass transfer during solvent extraction processes. Organic droplet data collected using the ViPA can be used to develop dispersion profiles of the liquid-liquid mixing and disengagements sections for each type of process equipment. These profiles will provide insight into mixing dynamics and will guide the prevention of emulsion formation that leads to system losses. Additionally, the measurement capabilities of the ViPA will provide the input needed to create new two-phase Computational Fluid Dynamics (CFD) models that characterize both mixing and separation operations in the various types of equipment. These models can then be used to improve process efficiency by optimizing operation parameters for each proposed extraction cycle.

On the Critical Delays of Mobile Networks under Levy Walks and Levy Flights  

E-Print Network (OSTI)

Delay-capacity tradeoffs for mobile networks have been analyzed through a number of research work, but L\\'{e}vy mobility has not been adopted in such research work due to its mathematical complexity. This paper analytically derives an important point in the delay-capacity tradeoffs, known as critical delay, the minimum delay required to achieve more throughput than $\\Theta(1/\\sqrt{n})$ where $n$ is the number of nodes in the network for L\\'{e}vy mobility: L\\'{e}vy flight and L\\'{e}vy walk. L\\'{e}vy mobility parametrized by its shape parameter $\\alpha \\in (0,2]$ is of special interest because it is known that L\\'{e}vy mobility and human mobility share several common features including heavy-tail step size distributions. Therefore, understanding the fundamental delay-capacity tradeoffs of L\\'{e}vy mobility provides important insight into understanding the performance of real mobile networks governed by human mobility. Our proposed technique involves an analysis of the joint spatio-temporal probability density f...

Enhancement In Charge Carrier Mobility Under Transition To Heavy Doping  

SciTech Connect

New experimental data confirming our suggestion about the universal character of critical phenomena accompanying the transition from 'an impurity gas' to 'an impurity condensate' with impurity concentration increasing are presented. The existence of the range of anomalous growth in the charge carrier mobility under transition to heavy doping is established for PbTe-PbSe solid solutions. The experimental results are analyzed on the basis of percolation theory taking into account alloy scattering and spatial correlations of impurity centers.

A study of mobile trough genesis over the Yellow Sea - East China Sea region  

E-Print Network (OSTI)

The purpose of this study was to understand the mechanisms responsible for the formation of mobile troughs over a prolific source region in the Yellow Sea and East China Sea. Two mobile troughs which intensified significantly after formation were analyzed. The troughs were selected from the objective climatology of mobile troughs by Lefevre and Nielsen-Gammon (1995). A quasigeostrophic potential vorticity (QGPV) and associated piecewise tendency diagnosis (PTD) technique developed by NielsenGammon and Lefevre (1995) was used to quantitatively analyze the dynamics of mobile trough formation. The PTD technique involves the inversion of QGPV and QGPV advection. A qualitative approach using dynamical tropopause maps of constant Ertel's potential vorticity (EPV) was utilized in conjunction with the QGPV method. It was determined that downstream development was the primary mechanism in initiating both mobile troughs. Type A cyclogenesis was not evident in either trough genesis event. A surface cyclone aided the development of one of the mobile troughs, but the cyclone had developed prior to the formation of the mobile trough. Baroclinic processes and large-scale interactions played lesser roles in one trough, but were not important in the other trough. Barotropic deformation modulated the strength of the second mobile trough by changing the shape of the associated QGPV anomaly. Vertical superposition was important in strengthening the latter stages of the life of the mobile trough, due to two jets superimposing over the mobile trough. Subjective analysis of tropopause maps of both trough genesis events showed the downstream development process as the growth of a new wave by cross-contour advection of potential temperature due to a pre-existing upstream disturbance.

Advanced mobile networking, sensing, and controls.  

SciTech Connect

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

An ion mobility spectrometer may include an inner electrode and an outer electrode arranged so that at least a portion of the outer electrode surrounds at least a portion of the inner electrode and defines a drift space therebetween. The inner and outer electrodes are electrically insulated from one another so that a non-linear electric field is created in the drift space when an electric potential is placed on the inner and outer electrodes. An ion source operatively associated with the ion mobility spectrometer releases ions to the drift space defined between the inner and outer electrodes. A detector operatively associated with at least a portion of the outer electrode detects ions from the drift space.

Use of mixed surfactants to generate foams for mobility control in chemical flooding  

Science Conference Proceedings (OSTI)

The application of mixed surfactant foams as an alternative method for mobility control behind a low-concentration chemical flood was evaluated in laboratory experiments. Results indicated that use of alternating slug cycles of gas and selected mixed surfactants resulted in significantly higher differential pressures, [Delta]p, compared with use of only the individual surfactant components, even at low surfactant concentrations. Foams generated with these systems were more stable, even in the presence of oil. The synergistic effect of enhancing foam-generation behavior and stability of these types of systems can improve propagation of a mobility-control front through porous media.

The Economic Mobility in Money Transfer Models  

E-Print Network (OSTI)

In this paper, we investigate the economic mobility in some money transfer models which have been applied into the research on monetary distribution. We demonstrate the mobility by recording the agents' ranks time series and observing the volatility. We also compare the mobility quantitatively by employing an index, "the per capita aggregate change in log-income", raised by economists. Like the shape of distribution, the character of mobility is also decided by the trading rule in these transfer models. It is worth noting that even though different models have the same type of distribution, their mobility characters may be quite different.

in print: Mobile Communities – New Business Opportunities for Mobile Network Operators  

E-Print Network (OSTI)

This paper presents the results of an analysis of potential revuenue streams and business models for mobile communities from a mobile network operator’s perspective. It gives a contribution to the answer of the actual business challenges in the mobile carrier sector where operators are continously searching for new innovative services and business models to increase their revenues and financial performance in the age of 3 rd generation mobile technology. Mobile communities are considered to be the next logical evolutional step of the existing virtual communities on the internet. The extension of web-based virtual communities with new community-orientated mobile services is expected to be enormously attractive – from the community user’s point of view as well as from the mobile operators ’ point of view: Mobile operators are playing the central part in terms of realisation and provision of these new services, since they own and build up the necessary technical infrastructure of mobile communication networks. Furthermore, mobile operators are considered to generate direct revenue streams out of mobile community-services, since they bill the connection fees of mobile services. Mobile communities and mobile community services are a very innovative topic. Despite all these great expectations, no empirical experiences have been made yet regarding this topic, since mobile communities are

Mobility control of caustic flood  

SciTech Connect

Displacement tests to date of oil field core with alkaline solutions at reservoir temperature show low tertiary oil recovery. Inadequate mobility control is singled out as the reason for such poor recovery. To test the validity of this reasoning, a laboratory study was undertaken in which a high heat resistant polymer was used as the mobility control agent in a hot alkaline solution recovery technique. A combination of varying concentration and volumes of the polymer solution was injected into the sandpack which was then flooded with hot sodium hydroxide solution. The range of polymer concentration was between 0.0% and 3.0%, while the volume varied between 0.0 pore volume and 1.7 pore volume. It was observed that polymer injection actually did improve recovery substantially and that there is an optimum concentration and slug size of polymer for a particular reservoir. Higher concentrations of pore volumes injected did not improve recovery significantly.

Distributed services for mobile ad hoc networks  

E-Print Network (OSTI)

A mobile ad hoc network consists of certain nodes that communicate only through wireless medium and can move arbitrarily. The key feature of a mobile ad hoc network is the mobility of the nodes. Because of the mobility, communication links form and disappear as nodes come into and go out of each other's communica- tion range. Mobile ad hoc networks are particularly useful in situations like disaster recovery and search, military operations, etc. Research on mobile ad hoc networks has drawn a huge amount of attention recently. The main challenges for mobile ad hoc networks are the sparse resources and frequent mobility. Most of the research work has been focused on the MAC and routing layer. In this work, we focus on distributed services for mobile ad hoc networks. These services will provide some fundamental functions in developing various applications for mobile ad hoc networks. In particular, we focus on the clock synchronization, connected dominating set, and k-mutual exclusion problems in mobile ad hoc networks.

Discursive Deployments: Mobilizing Support for Municipal and Community Wireless Networks in the U.S.  

Science Conference Proceedings (OSTI)

This paper examines Municipal Wireless (MW) deployments in the United States. In particular, the interest is in understanding how discourse has worked to mobilize widespread support for MW networks. We explore how local governments discursively deploy the language of social movements to create a shared understanding of the networking needs of communities. Through the process of"framing" local governments assign meaning to the MW networks in ways intended to mobilize support anddemobilize opposition. The mobilizing potential of a frame varies and is dependent on its centrality and cultural resonance. We examine the framing efforts of MW networks by using a sample of Request for Proposals for community wireless networks, semi-structured interviews and local media sources. Prominent values that are central to a majority of the projects and others that are culturally specific are identified and analyzed for their mobilizing potency.

Planet-scale Human Mobility Measurement  

E-Print Network (OSTI)

Research into, and design and construction of mobile systems and algorithms requires access to large-scale mobility data. Unfortunately, the wireless and mobile research community lacks such data. For instance, the largest available human contact traces contain only 100 nodes with very sparse connectivity, limited by experimental logistics. In this paper we pose a challenge to the community: how can we collect mobility data from billions of human participants? We re-assert the importance of large-scale datasets in communication network design, and claim that this could impact fundamental studies in other academic disciplines. In effect, we argue that planet-scale mobility measurements can help to save the world. For example, through understanding large-scale human mobility, we can track and model and contain the spread of epidemics of various kinds.

Pathogenicity island mobility and gene content.  

SciTech Connect

Key goals towards national biosecurity include methods for analyzing pathogens, predicting their emergence, and developing countermeasures. These goals are served by studying bacterial genes that promote pathogenicity and the pathogenicity islands that mobilize them. Cyberinfrastructure promoting an island database advances this field and enables deeper bioinformatic analysis that may identify novel pathogenicity genes. New automated methods and rich visualizations were developed for identifying pathogenicity islands, based on the principle that islands occur sporadically among closely related strains. The chromosomally-ordered pan-genome organizes all genes from a clade of strains; gaps in this visualization indicate islands, and decorations of the gene matrix facilitate exploration of island gene functions. A %E2%80%9Clearned phyloblocks%E2%80%9D method was developed for automated island identification, that trains on the phylogenetic patterns of islands identified by other methods. Learned phyloblocks better defined termini of previously identified islands in multidrug-resistant Klebsiella pneumoniae ATCC BAA-2146, and found its only antibiotic resistance island.

DIFFERENTIAL PULSE HEIGHT DISCRIMINATOR  

DOE Patents (OSTI)

Pulse-height discriminators are described, specifically a differential pulse-height discriminator which is adapted to respond to pulses of a band of amplitudes, but to reject pulses of amplitudes greater or less than tbe preselected band. In general, the discriminator includes a vacuum tube having a plurality of grids adapted to cut off plate current in the tube upon the application of sufficient negative voltage. One grid is held below cutoff, while a positive pulse proportional to the amplltude of each pulse is applled to this grid. Another grid has a negative pulse proportional to the amplitude of each pulse simultaneously applied to it. With this arrangement the tube will only pass pulses which are of sufficlent amplitude to counter the cutoff bias but not of sufficlent amplitude to cutoff the tube.

Dynamic Analysis of Mobile Device Applications  

SciTech Connect

The On-Device Dynamic Analysis of Mobile Applications (ODAMA) project was started in an effort to protect mobile devices used in Industrial Control Systems (ICS) from cyber attack. Because mobile devices hide as much of the “computer” as possible, the user’s ability to assess the software running on their system is limited. The research team chose Google’s Android platform for this initial research because it is open source and it would give us freedom in our approach, including the ability to modify the mobile device’s operating system itself. The research team concluded that a Privileged Application was the right approach, and the result was ODAMA. This project is an important piece of the work to secure the expanding use of mobile devices with our nation’s critical infrastructure.

Isotopic Effect on Ion Mobility and Separation of Isotopomers by High-Field Ion Mobility Spectrometry  

SciTech Connect

Since early 1900-s, when vacuum techniques and ion detectors first enabled investigations of gas-phase ions, two approaches to their separation and characterization have emerged - mass spectrometry (MS) and ion mobility spectrometry (IMS).1,2 Though both exploit that distinct charged species move in electric fields differently, MS is performed in vacuum and is based only on the ion mass/charge (m/q) ratio while IMS involves sufficiently dense buffer gases and relies on ion transport properties. The first major discovery enabled by MS was the existence of isotopes by Thomson and Aston,3 and isotopic analyses have since been integral to MS. In particular, the preparative separation of U isotopes using Lawrence’s Calutron was the first industrial application of MS,4 and isotopic labeling is key to MS quantification methods. With IMS, the issue of isotopes was largely ignored as the resolving power (R) was generally too low for their separation. Here, we demonstrate that recently developed high-resolution differential IMS can separate isotopic molecular ions, including nominal isobars with different isotopic content and isotopomers. This capability may enable a new method for isotope separation in a small-scale format at ambient pressure and aid localization of labeled sites in various molecules. Perhaps most importantly, the isotopic shifts depend on the labeled atom position and thus may contain the kind of detailed structural information that is available in solution or solid state using tools such as NMR but has not generally been obtainable for gas-phase ions.

Analysis of a turbine trip test with a plant analyzer  

SciTech Connect

To improve nuclear power plant safety, the Taiwan Power Company is using a plant analyzer developed by Brookhaven National Laboratory (BNL). The BNL boiling water reactor (BWR) plant analyzer program was converted and modified for the Chinshan power station using the ADSIM simulation language. The plant analyzer uses a special-purpose peripheral processor, the AD-100 from the Applied Dynamic International Company, and detailed mathematical models. With the fast-computing features of the AD-100, the plant analyzer can carry out accurate and fast simulations of nuclear power plant transients. To qualify this program, simulation results were benchmarked against power test data. During a power test a Chinshan unit 1, a 1175-MW(thermal) boiling water reactor (BWR), a turbine trip test was performed from a steady-state condition of 83% of rated core power and 80% of rated core flow. It was initiated by a manual trip of the turbine. The purpose of this work is to simulate the turbine trip transient with the plant analyzer and compare the results with plant test data.

Increasing Confidence of LC-MS Identifications by Utilizing Ion Mobility Spectrometry  

SciTech Connect

Ion mobility spectrometry in conjunction with liquid chromatography separations and mass spectrometry offers a range of new possibilities for analyzing complex biological samples. To fully utilize the information obtained from these three measurement dimensions, informatics tools based on the accurate mass and time tag methodology were modified to incorporate ion mobility spectrometry drift times for peptides observed in human serum. A reference human serum database was created using 12,139 peptides, tracking the monoisotopic mass, liquid chromatography normalized elution time, and ion mobility spectrometry drift time(s) for each peptide. We demonstrate that the use of three dimensions for peak matching during the peptide identification process resulted in increased numbers of identifications and lower false discovery rates relative to the use of only the mass and normalized elution time dimensions.

Method for tracking the location of mobile agents using stand-off detection technique  

DOE Patents (OSTI)

A method for tracking the movement and position of mobile agents using light detection and ranging (LIDAR) as a stand-off optical detection technique. The positions of the agents are tracked by analyzing the time-history of a series of optical measurements made over the field of view of the optical system. This provides a (time+3-D) or (time+2-D) mapping of the location of the mobile agents. Repeated pulses of a laser beam impinge on a mobile agent, such as a bee, and are backscattered from the agent into a LIDAR detection system. Alternatively, the incident laser pulses excite fluorescence or phosphorescence from the agent, which is detected using a LIDAR system. Analysis of the spatial location of signals from the agents produced by repeated pulses generates a multidimensional map of agent location.

A Tiered Security System for Mobile Devices  

E-Print Network (OSTI)

We have designed a tiered security system for mobile devices where each security tier holds user-defined security triggers and actions. It has a friendly interface that allows users to easily define and configure the different circumstances and actions they need according to context. The system can be set up and activated from any browser or directly on the mobile device itself. When the security system is operated from a Web site or server, its configuration can be readily shared across multiple devices. When operated directly from the mobile device, no server is needed for activation. Many different types of security circumstances and actions can be set up and employed from its tiers. Security circumstances can range from temporary misplacement of a mobile device at home to malicious theft in a hostile region. Security actions can range from ringing a simple alarm to automatically erasing, overwriting, and re-erasing drives.

Power-Aware Communication for Mobile Computers  

E-Print Network (OSTI)

Recently, the mobile community has focused on techniques for reducing energy consumption for mobile hosts. These power management techniques typically target communication devices such as wireless network interfaces, aiming to reduce usage, and thus energy consumption, of the particular device itself. We observe that optimization of a single device's energy consumption, without considering the effect of the strategy on the rest of the machine, can have negative consequences. We propose power management techniques addressing mobile host communications that encompass all components of a mobile host in an effort to optimize total energy consumption. Specifically, we propose runtime adaptation of communication parameters in order to minimize the energy consumed during active data transfer. Information about the network environment is used to drive such adaptations in an effort to compensate for the effect of dynamic service from wireless communication device on the energy consume...

Entropic measures of individual mobility patterns  

E-Print Network (OSTI)

Understanding human mobility from a microscopic point of view may represent a fundamental breakthrough for the development of a statistical physics for cognitive systems and it can shed light on the applicability of macroscopic statistical laws for social systems. Even if the complexity of individual behaviors prevents a true microscopic approach, the introduction of mesoscopic models allows the study of the dynamical properties for the non-stationary states of the considered system. We propose to compute various entropy measures of the individual mobility patterns obtained from GPS data that record the movements of private vehicles in the Florence district, in order to point out new features of human mobility related to the use of time and space and to define the dynamical properties of a stochastic model that could generate similar patterns. Moreover, we can relate the predictability properties of human mobility to the distribution of time passed between two successive trips. Our analysis suggests the exist...

Interaction control of a redundant mobile manipulator  

SciTech Connect

This paper discusses the modeling and control of a spatial mobile manipulator that consists of a robotic manipulator mounted on a wheeled mobile platform. The Lagrange-d`Alembert formulation is used to obtain a concise description of the dynamics of the system, which is subject to nonholonomic constraints. The complexity of the model is increased by introducing kinematic redundancy, which is created when a multilinked manipulator is used. The kinematic redundancy is resolved by decomposing the mobile manipulator into two subsystems: the mobile platform and the manipulator. The redundancy resolution scheme employs a nonlinear interaction-control algorithm, which is developed and applied to coordinate the two subsystems` controllers. The subsystem controllers are independently designed, based on each subsystem`s dynamic characteristics. Simulation results show the promise of the developed algorithm.

The research will use new seismic sources that emphasize shear waves and new seismic data-acquisition technology based on cable-free data recording to acquire seismic research data across two sites covered with surface-exposed highvelocity rocks. Research tasks will involve acquiring, processing, and interpreting both conventional seismic data and multicomponent seismic data. Scientists at BEG will analyze well logs, cores, and reservoir test data to construct geological models of the targeted geology across each study site.

MOBILIZATION AND CHARACTERIZATION OF COLLOIDS GENERATED FROM CEMENT LEACHATES MOVING THROUGH A SRS SANDY SEDIMENT  

Science Conference Proceedings (OSTI)

Naturally occurring mobile colloids are ubiquitous and are involved in many important processes in the subsurface zone. For example, colloid generation and subsequent mobilization represent a possible mechanism for the transport of contaminants including radionuclides in the subsurface environments. For colloid-facilitated transport to be significant, three criteria must be met: (1) colloids must be generated; (2) contaminants must associate with the colloids preferentially to the immobile solid phase (aquifer); and (3) colloids must be transported through the groundwater or in subsurface environments - once these colloids start moving they become 'mobile colloids'. Although some experimental investigations of particle release in natural porous media have been conducted, the detailed mechanisms of release and re-deposition of colloidal particles within natural porous media are poorly understood. Even though this vector of transport is known, the extent of its importance is not known yet. Colloid-facilitated transport of trace radionuclides has been observed in the field, thus demonstrating a possible radiological risk associated with the colloids. The objective of this study was to determine if cementitious leachate would promote the in situ mobilization of natural colloidal particles from a SRS sandy sediment. The intent was to determine whether cementitious surface or subsurface structure would create plumes that could produce conditions conducive to sediment dispersion and mobile colloid generation. Column studies were conducted and the cation chemistries of influents and effluents were analyzed by ICP-OES, while the mobilized colloids were characterized using XRD, SEM, EDX, PSD and Zeta potential. The mobilization mechanisms of colloids in a SRS sandy sediment by cement leachates were studied.

A Statecharts-Based Methodology for the Simulation of Mobile Agents  

E-Print Network (OSTI)

Mobile agent paradigm and technology are profitably being applied for the construction of a wide range of applications and systems in several areas encompassing e-business, telecommunications, meta-computing and military simulations. Such systems are usually complex so requiring methodologies and tools for an in-depth understanding of their dynamics and for their validation. This paper presents and exemplifies a methodology for modeling and validation through simulation of mobile agents based systems and applications. Mobile agents are modeled as asynchronous, event-driven single threaded entities whose behavior is specified using Distilled Statecharts. A distilled statechart, which embeds both the activity and the interactions a mobile agent performs during its lifecycle, can be easily translated into a Java composite object using the mobile active object framework. In order to analyze an agent-based system, a discrete-event, reflective simulation framework which allows for concurrency, timing and meta-level customization, is used. A case study is also provided which highlights the main features of the proposed methodology.

Landmark routing in ad hoc networks with mobile backbones  

E-Print Network (OSTI)

A Mobile Ad Hoc Network (MANET) is usually assumed to be homogeneous, where each mobile node shares the same radio capacity. However, a homogeneous ad hoc network suffers from poor scalability. Recent research has demonstrated its performance bottleneck through both theoretical analysis and simulation experiments and testbed measurements. This is further exacerbated by heavy routing overhead of ad hoc routing protocols when the network size is large. In this paper, we present a design methodology to build a hierarchical large-scale ad hoc network using different types of radio capabilities at different layers. In such a structure, nodes are first dynamically grouped into multi-hop clusters. Each group elects a cluster-head to be a backbone node (BN). Then higher-level links are established to connect the BNs into a backbone network. Following this method recursively, a multilevel hierarchical network can be established. Three critical issues are addressed in this paper. We first analyze the optimal number of BNs for a layer in theory. Then, we propose a stable and light overhead clustering scheme to deploy the BNs. Finally LANMAR routing is extended to operate the physical hierarchy efficiently. We show that the Hierarchical LANMAR (H-LANMAR) can incorporate and efficiently utilize backbone links to reach remote destinations (thus reducing the hop distance). Simulation results using GloMoSim confirm that our proposed schemes achieve good performance.

Analyzing occupancy profiles from a lighting controls field study  

SciTech Connect

Despite a number of published studies on the effectiveness of lighting controls in buildings, only one US study examines the occupancy patterns of building occupants. Occupancy profiles allow one to determine, for example, the probability that an office is occupied for each hour of the workday. Occupancy profiles are useful for many purposes including: (1) predicting the effectiveness of occupancy sensors for reducing peak demand, (2) evaluating the impact of human activity on building lighting and other electric loads and (3) providing lighting equipment manufacturers with detailed lighting operation data to help evaluate the impact of advanced lighting controls on equipment life. In this paper, we examine the occupancy profiles for 35 single person offices at a large office building in San Francisco and analyze the data to obtain average occupancy as a function of time of day. In addition, we analyzed the data to identify how the use of occupancy sensors may affect switching cycles and lamp life.

Pulsed Neurton Elemental On-Line Material Analyzer  

DOE Patents (OSTI)

An on-line material analyzer which utilizes pulsed neutron generation in order to determine the composition of material flowing through the apparatus. The on-line elemental material analyzer is based on a pulsed neutron generator. The elements in the material interact with the fast and thermal neutrons produced from the pulsed generator. Spectra of gamma-rays produced from fast neutrons interacting with elements of the material are analyzed and stored separately from spectra produced from thermal neutron reactions. Measurements of neutron activation takes place separately from the above reactions and at a distance from the neutron generator. A primary passageway allows the material to flow through at a constant rate of speed and operators to provide data corresponding to fast and thermal neutron reactions. A secondary passageway meters the material to allow for neutron activation analysis. The apparatus also has the capability to determine the density of the flowed material. Finally, the apparatus continually utilizes a neutron detector in order to normalize the yield of the gamma ray detectors and thereby automatically calibrates and adjusts the spectra data for fluctuations in neutron generation.

DEVELOPMENT OF AN ON-LINE COAL WASHABILITY ANALYZER  

SciTech Connect

Washability analysis is the basis for nearly all coal preparation plant separations. Unfortunately, there are no on-line techniques for determining this most fundamental of all coal cleaning information. In light of recent successes at the University of Utah, it now appears possible to determine coal washability on-line through the use of x-ray computed tomography (CT) analysis. The successful development of such a device is critical to the establishment of process control and automated coal blending systems. In this regard, Virginia Tech, Terra Tek Inc., and several eastern coal companies have joined with the University of Utah and agreed to undertake the development of a x-ray CT-based on-line coal washability analyzer with financial assistance from DOE. The three-year project will cost $594,571, of which 33% ($194,575) will be cost-shared by the participants. The project involves development of appropriate software and extensive testing/evaluation of well-characterized coal samples from operating coal preparation plants. Each project participant brings special expertise to the project which is expected to create a new dimension in coal cleaning technology. Finally, it should be noted that the analyzer may prove to be a universal analyzer capable of providing not only washability analysis, but also particle size distribution analysis, ash analysis and perhaps pyritic sulfur analysis.

A GIS-based Bayesian approach for analyzing spatial-temporal patterns of traffic crashes  

E-Print Network (OSTI)

This thesis develops a GIS-based Bayesian approach for area-wide traffic crash analysis. Five years of crash data from Houston, Texas, are analyzed using a geographic information system (GIS), and spatial-temporal patterns of relative crash risk are identified based on a hierarchical Bayesian approach. This Bayesian approach is used to filter the uncertainty in the data and identify and rank roadway segments with potentially high relative risks for crashes. The results provide a sound basis to take preventive actions to reduce the risks in these segments. To capture the real safety indications better, this thesis differentiates the risks in different directions of the roadways, disaggregates different road types, and utilizes GIS to analyze and visualize the spatial relative crash risks in 3-D views according to different temporal scales. Results demonstrate that the approach is effective in spatially smoothing the relative crash risks, eliminating the instability of estimates while maintaining real safety trends. The posterior risk maps show high-risk roadway segments in 3-D views, which is more reader friendly than the conventional 2-D views. The results are also useful for travelers to choose relatively safer routes.

Design of a Real-Time Scanning Electrical Mobility Spectrometer and its Application in Study of Nanoparticle Aerosol Generation  

E-Print Network (OSTI)

A real-time, mobile Scanning Electrical Mobility Spectrometer (SEMS) was designed using a Condensation Particle Counter (CPC) and Differential Mobility Analyzer (DMA) to measure the size distribution of nanoparticles. The SEMS was calibrated using monodisperse Polystyrene Latex (PSL) particles, and was then applied to study the size distribution of TiO2 nanoparticle aerosols generated by spray drying water suspensions of the nanoparticles. The nanoparticle aerosol size distribution, the effect of surfactant, and the effect of residual solvent droplets were determined. The SEMS system was designed by integrating the Electrical System, the Fluid Flow System, and the SEMS Software. It was calibrated using aerosolized Polystyrene Latex (PSL) spheres with nominal diameters of 99 nm and 204 nm. TiO2 nanoparticle aerosols were generated by atomizing water suspensions of TiO2 nanoparticles using a Collison nebulizer. Size distribution of the TiO2 aerosol was measured by the SEMS, as well as by TEM. Furthermore, the effect of surfactant, Tween 20 at four different concentrations between 0.01mM and 0.80mM, and stability of aerosol concentration with time were studied. It was hypothesized that residual particles in DI water observed during the calibration process were a mixture of impurities in water and unevaporated droplets. Solid impurities were captured on TEM grids using a point-to-plane Electrostatic Precipitator (ESP) and analyzed by Energy Dispersive Spectroscopy (EDS) while the contribution of unevaporated liquid droplets to residual particles was confirmed by size distribution measurements of aerosolized DI water in different humidity conditions. The calibration indicated that the mode diameter was found to be at 92.5nm by TEM and 95.8nm by the SEMS for 99nm nominal diameter particles, a difference of 3.6%. Similarly, the mode diameter for 204nm nominal diameter particles was found to be 194.9nm by TEM and 191nm by SEMS, a difference of 2.0%. Measurements by SEMS for TiO2 aerosol generated by Collison nebulizer indicated the mode diameters of 3mM, 6mM, and 9mM concentrations of TiO2 suspension to be 197.5nm, 200.0nm and 195.2nm respectively. On the other hand, the mode diameter was found to be approximately 95nm from TEM analysis of TiO2 powder. Additionally, concentration of particles generated decreased with time. Dynamic Light Scattering (DLS) measurements indicated agglomeration of particles in the suspension. Furthermore, the emulation of single particle distribution was not possible even after using Tween 20 in concentrations between 0.01mM and 0.80mM. From the study of residual particles in DI water, it was found that residual particles observed during the aerosolization of suspensions of DI water were composed of impurities present in DI water and unevaporated droplets of DI water. Although it was possible to observe solid residual particles on the TEM grid, EDS was not able to determine the chemical composition of these particles.

Methods for Analyzing Electric Load Shape and its Variability  

Science Conference Proceedings (OSTI)

Current methods of summarizing and analyzing electric load shape are discussed briefly and compared. Simple rules of thumb for graphical display of load shapes are suggested. We propose a set of parameters that quantitatively describe the load shape in many buildings. Using the example of a linear regression model to predict load shape from time and temperature, we show how quantities such as the load?s sensitivity to outdoor temperature, and the effectiveness of demand response (DR), can be quantified. Examples are presented using real building data.

National science policy and scientific manpower: Funding effects on job mobility of scientists and engineers in the United States, 1958--1972  

Science Conference Proceedings (OSTI)

Science policy in the United States between 1958 and 1972 was intended to influence the research and development (R D) labor force indirectly, through government funding. An event history analysis of professional R D jobs in five scientific disciplines shows that, while federal funding influences the job mobility of scientists and engineers, other social and economic factors are also significant in explaining mobility patterns. Federal funding significantly decreases the rates of job mobility in all disciplines during the period, stabilizing the employment structure. Indicators of reward-resource arguments-salary, age, and education-significantly affect job mobility. Consistent with human capital and job matching arguments, salary and age significantly reduce mobility. Education is significant only in life science, physical science, and engineering, where higher education leads to increased mobility. Indicators of limited opportunity arguments-socioeconomic background, sex, and ethnicity-show mixed empirical results. Labour markets also significantly affect mobility. In engineering and physical science, a neo-institutional model, which accounts for the degree of government oversight, fits the data best. Social science and life science are best fit by performance sectors, which highlight the importance of universities as employers for these disciplines. Mathematical science is best fit by a model of industrial sectors, consistent with differential expansion of the economy that disproportionately affected this discipline. Federal funding has acted to institutionalize R D in the economy and stabilize employment; it has not insulated workers from general socioeconomic factors such as human capital, discrimination and labour markets.

A Reference Based Analysis Framework for Analyzing System Call Traces  

SciTech Connect

Reference based analysis (RBA) is a novel data mining tool for exploring a test data set with respect to a reference data set. The power of RBA lies in it ability to transform any complex data type, such as symbolic sequences and multi-variate categorical data instances, into a multivariate continuous representation. The transformed representation not only allows visualization of the complex data, which cannot be otherwise visualized in its original form, but also allows enhanced anomaly detection in the transformed feature space. We demonstrate the application of the RBA framework in analyzing system call traces and show how the transformation results in improved intrusion detection performance over state of art data mining based intrusion detection methods developed for system call traces.

We report a precision measurement of the deuteron tensor analyzing powers T{sub 20} and T{sub 21} at the MIT-Bates Linear Accelerator Center. Data were collected simultaneously over a momentum transfer range Q=2.15-4.50 fm{sup -1} with the Bates Large Acceptance Spectrometer Toroid using a highly polarized deuterium internal gas target. The data are in excellent agreement with calculations in a framework of effective field theory. The deuteron charge monopole and quadrupole form factors G{sub C} and G{sub Q} were separated with improved precision, and the location of the first node of G{sub C} was confirmed at Q=4.19{+-}0.05 fm{sup -1}. The new data provide a strong constraint on theoretical models in a momentum transfer range covering the minimum of T{sub 20} and the first node of G{sub C}.

SciTech Connect

The project "Analyzing and visualizing next generation climate data" adds block-structured (mosaic) grid support, parallel processing, and 2D/3D curvilinear interpolation to the open-source UV-CDAT climate data analysis tool. Block structured grid support complies to the Gridspec extension submitted to the Climate and Forecast metadata conventions. It contains two parts: aggregation of data spread over multiple mosaic tiles (M-SPEC) and aggregation of temporal data stored in different files (F-SPEC). Together, M-SPEC and F-SPEC allow users to interact with data stored in multiple files as if the data were in a single file. For computational expensive tasks, a flexible, multi-dimensional, multi-type distributed array class allows users to process data in parallel using remote memory access. Both nodal and cell based interpolation is supported; users can choose between different interpolation libraries including ESMF and LibCF depending on the their particular needs.

Analyzing and Tracking Burning Structures in Lean Premixed Hydrogen Flames  

DOE Green Energy (OSTI)

This paper presents topology-based methods to robustly extract, analyze, and track features defined as subsets of isosurfaces. First, we demonstrate how features identified by thresholding isosurfaces can be defined in terms of the Morse complex. Second, we present a specialized hierarchy that encodes the feature segmentation independent of the threshold while still providing a flexible multi-resolution representation. Third, for a given parameter selection we create detailed tracking graphs representing the complete evolution of all features in a combustion simulation over several hundred time steps. Finally, we discuss a user interface that correlates the tracking information with interactive rendering of the segmented isosurfaces enabling an in-depth analysis of the temporal behavior. We demonstrate our approach by analyzing three numerical simulations of lean hydrogen flames subject to different levels of turbulence. Due to their unstable nature, lean flames burn in cells separated by locally extinguished regions. The number, area, and evolution over time of these cells provide important insights into the impact of turbulence on the combustion process. Utilizing the hierarchy we can perform an extensive parameter study without re-processing the data for each set of parameters. The resulting statistics enable scientist to select appropriate parameters and provide insight into the sensitivity of the results wrt. to the choice of parameters. Our method allows for the first time to quantitatively correlate the turbulence of the burning process with the distribution of burning regions, properly segmented and selected. In particular, our analysis shows that counter-intuitively stronger turbulence leads to larger cell structures, which burn more intensely than expected. This behavior suggests that flames could be stabilized under much leaner conditions than previously anticipated.

Intraspecific relationships among the stygobitic shrimp Typhlatya mitchelli, by analyzing sequence data from mitochondrial DNA  

E-Print Network (OSTI)

Intraspecific relationships among the anchialine cave shrimp Typhlatya mitchelli were examined by sequencing a total of 1505 bp from portions of three mitochondrial DNA genes. Cytochrome b, cytochrome oxidase I, and 16S rRNA were partially sequenced and analyzed for specimens from six different cenotes (water-filled caves) across the Yucatan Peninsula, Mexico. The conspecific Typhlatya pearsei that is sympatric with T. mitchelli was also sequenced and used as the outgroup. Comparisons among specimens of T. mitchelli yielded low sequence divergence values (0-1.7%), with the majority being less than 0.4%. Phylogenetic tree topologies reconstructed with neighbor-joining, maximum likelihood, and maximum parsimony were in agreement in regards of the resolution of deep branches. Also, there was no obvious geographic differentiation among the majority of T. mitchelli samples, with the exception of specimens from Cenote San Antonio Chiich (Yokdzonot, Yucatan, Mexico) which all clustered into an extremely well supported monophyletic group. The level of differentiation of this group, together with the nearly total absence of differentiation among T. mitchelli from distant cave systems, suggests that this is an Evolutionary Significant Unit (ESU), which may correspond to a new species. This unidentified Typhlatya from Cenote San Antonio Chiich was helpful in establishing a period in which the epigean ancestor colonized the cenotes. Based on pairwise distance data and previously published shrimp molecular clocks (Baldwin et al., 1998), T. mitchelli and the putative new Typhlatya species last shared a common ancestor between 3-5 million years ago (mya), during the mid-Pliocene era, while T. mitchelli and T. pearsei was approximately 7-10 mya (middle to late Miocene). The ancestor to T. mitchelli and the unidentified Typhlatya species abandoned its shallow coastal water existence in the early Pliocene and eventually expanded its range across the peninsula. Approximately 4 mya, Cenote San Antonio Chiich became isolated from the remaining gene pool thereby halting gene flow. As the regional water table fluctuated in response to the rise and fall of Pleistocene sea levels, T. mitchelli actively colonized the peninsula. The discovery of a single, continuous subterranean freshwater system provides for a better understanding of anchialine biogeography within the Yucatan Peninsula.

Mobile workstation for decontamination and decommissioning operations  

SciTech Connect

This project is an interdisciplinary effort to develop effective mobile worksystems for decontamination and decommissioning (D&D) of facilities within the DOE Nuclear Weapons Complex. These mobile worksystems will be configured to operate within the environmental and logistical constraints of such facilities and to perform a number of work tasks. Our program is designed to produce a mobile worksystem with capabilities and features that are matched to the particular needs of D&D work by evolving the design through a series of technological developments, performance tests and evaluations. The project has three phases. In this the first phase, an existing teleoperated worksystem, the Remote Work Vehicle (developed for use in the Three Mile Island Unit 2 Reactor Building basement), was enhanced for telerobotic performance of several D&D operations. Its ability to perform these operations was then assessed through a series of tests in a mockup facility that contained generic structures and equipment similar to those that D&D work machines will encounter in DOE facilities. Building upon the knowledge gained through those tests and evaluations, a next generation mobile worksystem, the RWV II, and a more advanced controller will be designed, integrated and tested in the second phase, which is scheduled for completion in January 1995. The third phase of the project will involve testing of the RWV II in the real DOE facility.

User Interfaces for Mobile Augmented Reality Systems  

E-Print Network (OSTI)

In this dissertation, we present typical components of, useful services associated with, and user interactions possible with mobile augmented reality systems, based on a comprehensive series of hardware and software infrastructures and application prototypes we developed. We define a practical taxonomy of user interface components for such systems and establish methodology for adaptive mobile augmented reality interfaces that dynamically rearrange themselves in response to changes in user context. The research contributions to the state-of-the-art in augmented reality begin with the author’s participation in the design of the ”Columbia Touring Machine ” in 1997, the first example of an outdoor mobile augmented reality system, and his lead in developing later prototypes. We develop a series of hardware and software infrastructures for prototyping mobile augmented reality applications that allow multiple users to participate in collaborative tasks taking place indoors and outdoors. We present exploratory user interfaces for many different applications and user scenarios, including the Situated Documentaries application framework for experiencing spatially distributed hypermedia presentations. Based on these explorations, we develop

How Does the User Interface Design of Mobile Devices Influence the Social Impact of Mobile Communication?  

E-Print Network (OSTI)

This paper describes how user interface design of mobile devices interacts with the social impact of mobile communication. Social impact is defined as the influence on relationships between social actors. In the light of mobile communication, one can distinguish among at least three relevant classes of relationships: human-machine relationships, interpersonal relationships between co-located persons, and machine mediated human-human relationships. The characteristics of each class are described, which lead to 13 statements about which social phenomena are important to this specific relationship, e.g., Being aware of the social context of the other party before initiating a communication and during the act of communication might have a significant positive social impact on the interaction outcome. Each statement is followed by a set of user interface design suggestions about how mobile communication user interfaces should be built in order to support the statement, or not to violate the social phenomena regarding a relationship described in the statement, or to make the social impact of mobile communication positive. Adding up across all three classes, 28 concrete user interface design suggestions are described that influence the social impact of mobile communication. 2. Preamble I define the term social impact pragmatically as the influence on relationships between social actors. In the context of mobile communication, there are three relevant classes of relationships: 1. human-machine relationships 2. interpersonal relationships among co-located persons 3. machine mediated human-human relationships. More specifically, the user interface design of a mobile device impacts these relationships by modifying social attributions, human behavior, and interaction outcome. In a...

The tradeoff between energy efficiency and user state estimation accuracy in mobile sensing  

E-Print Network (OSTI)

Abstract. People-centric sensing and user state recognition can provide rich contextual information for various mobile applications and services. However, continuously capturing this contextual information on mobile devices drains device battery very quickly. In this paper, we study the tradeoff between device energy consumption and user state recognition accuracy from a novel perspective. We assume the user state evolves as a hidden discrete time Markov chain (DTMC) and an embedded sensor on mobile device discovers user state by performing a sensing observation. We investigate a stationary deterministic sensor sampling policy which assigns different sensor duty cycles based on different user states, and propose two state estimation mechanisms providing the best “guess ” of user state sequence when observations are missing. We analyze the effect of varying sensor duty cycles on (a) device energy consumption and (b) user state estimation error, and visualize the tradeoff between the two numerically for a two-state setting. Key words: mobile sensing, energy efficiency, user state estimation accuracy, tradeoff 1

EBizPort: Collecting and Analyzing Business Intelligence Information  

E-Print Network (OSTI)

To make good decisions, businesses try to gather good intelligence information. Yet managing and processing a large amount of unstructured information and data stand in the way of greater business knowledge. An effective business intelligence tool must be able to access quality information from a variety of sources in a variety of forms, and it must support people as they search for and analyze that information. The EBizPort system was designed to address information needs for the business/IT community. EBizPort’s collection-building process is designed to acquire credible, timely, and relevant information. The user interface provides access to collected and metasearched resources using innovative tools for summarization, categorization, and visualization. The effectiveness, efficiency, usability, and information quality of the EBizPort system were measured. EBizPort significantly outperformed Brint, a business search portal, in search effectiveness, information quality, user satisfaction, and usability. Users particularly liked EBizPort’s clean and user-friendly interface. Results from our evaluation study suggest that the visualization function added value to the search and analysis process, that the generalizable collection-building technique can be useful for domain-specific information searching on the Web, and that the search interface was important for Web search and browse support.

Method and system for analyzing and classifying electronic information  

DOE Patents (OSTI)

A data analysis and classification system that reads the electronic information, analyzes the electronic information according to a user-defined set of logical rules, and returns a classification result. The data analysis and classification system may accept any form of computer-readable electronic information. The system creates a hash table wherein each entry of the hash table contains a concept corresponding to a word or phrase which the system has previously encountered. The system creates an object model based on the user-defined logical associations, used for reviewing each concept contained in the electronic information in order to determine whether the electronic information is classified. The data analysis and classification system extracts each concept in turn from the electronic information, locates it in the hash table, and propagates it through the object model. In the event that the system can not find the electronic information token in the hash table, that token is added to a missing terms list. If any rule is satisfied during propagation of the concept through the object model, the electronic information is classified.

Pushing the Frontier of High-Definition Ion Mobility Spectrometry Using FAIMS  

Science Conference Proceedings (OSTI)

Differential ion mobility spectrometry (FAIMS) separates ions in gases based on the difference between their mobilities in strong and weak electric fields, captured directly employing a periodic waveform with dissimilar profiles in opposite polarities. As that difference is not tightly correlated with the ion size or mass, FAIMS separations are generally quite orthogonal to both conventional IMS (based on the absolute ion mobility that reflects the physical ion size) and mass spectrometry (based on mass). Until a few years ago, that advantage was largely offset by poor FAIMS resolving power (?10–20), an order of magnitude below that achieved with conventional (drift-tube) IMS. This article summarizes the major recent technical developments that have raised FAIMS resolving power up to ?500. These include use of higher and more stable voltages provided by new waveform generators, novel buffer gas compositions comprising high helium or hydrogen fractions, and extended filtering times up to ?1 s. These advances have enabled previously unthinkable analyses such as broad baseline separations of peptide sequence inversions, localization variants (post-translationally modified peptides with differing PTM attachment sites) even for the larger “middle-down” peptides and smallest PTMs, and lipid regioisomers.

Trichostatin-A induces differential changes in histone protein dynamics and expression in HeLa cells  

SciTech Connect

Trichostatin-A (TSA), a histone deacetylase (HDAC) inhibitor, results in enhanced acetylation of core histones thereby disrupting chromatin organization within living cells. We report on changes in chromatin organization and the resultant alteration in nuclear architecture following treatment with TSA using fluorescence imaging. TSA triggers an expected increase in the euchromatin fraction which is accompanied by a significant increase in nuclear volume and alterations in chromatin compaction mapped using fluorescence anisotropy imaging. We observe differential changes in the mobility of core and linker histones as measured by fluorescence recovery after photo-bleaching (FRAP) and fluorescence correlation spectroscopy (FCS) methods. Further TSA induces a differential increase in linker histone transcription and increased phosphorylation of linker histone proteins accompanying an expected increase in core histone acetylation patterns. Thus subtle feedback responses triggered by changes in chromatin configurations impinge selectively on linker histone mobility and its expression. These observations have implications for understanding the role of HDAC in the dynamic maintenance of chromatin organization.

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.

Evaluating The Performance Of Mobile Agents In Network Management  

E-Print Network (OSTI)

Currently, most network management systems are centralized and therefore, they can not scale when the size or the complexity of the network increases. This paper aims to investigate mobile agent scalability in network management, in order to nd when mobile agents improve the management efficiency. We compare mobile agent performance with SNMP one in several simulations. Results show that the mobile agent performs better when the number of managed network elements ranges between two bounds and that the mobile agent is less sensitive to changes on a general topology.

Industrialization and Social Mobility in Korea  

E-Print Network (OSTI)

This study intends to investigate the patterns of intergenerational mobility among Korean men and to assess the extent to which the Korean case shows distinctiveness within the framework of the core model proposed by Erikson and Goldthorpe (1992a). The greater dissimilarity between origins and destinations associated with massive movement of labor forces out of farm origins, and in the process the predominance of upward over downward mobility are distinctive features of Korea compared to England, France, and Sweden. More importantly, Korean society shows substantial deviations from the core model as four effects among original eight effects in the core more turn out to be non-significant. Finally, the analysis of the log-multiplicative layer effect model even suggests that the overall level of fluidity appears higher in Korea relative to the three European countries. 1
