FIELD TESTING AND EVALUATION OF THE TRANSIT INTEGRATED MONITORING SYSTEM (1998)

This Innovations Deserving Exploratory Analysis (IDEA) project is a follow-up to the IDEA TRANSIT-10 project which indicated the potential of using radio frequency identification to integrate automatic passenger counting (APC) systems and automatic vehicle location (AVL) systems. This follow-up Phase 2 demonstration examined the integration of APC/AVL and other monitoring functions in the form of a Transit Integrated Monitoring System (TIMS). This project specifically addressed the following three needs: (1) Advanced systems for transit vehicle location, identification, and management of transit systems; (2) Improved methods of data collection about or from transit users; and (3) Advanced systems for fare collection and control systems. The Phase 2 overall project objectives included developing a demonstration system that: (1) improves the hardware components of the system; (2) enhances the software components of the system; and (3) enables a better understanding of the operational performance of TIMS under transit conditions. The results of this project included a completed software conceptual model of the information content for the system, a set of use cases for the system, a design specification for the database, a design specification for the user interface, and the hardware requirements and specifications. In addition, the software and hardware were implemented and installed on a bus within the Charlottesville Transit System. The system was tested during a field trial of one week. The final product associated with this project is the completed design and specifications of TIMS, the integrated hardware and software, and a demonstrated system.
A 462GOPs/J RRAM-based nonvolatile intelligent processor for energy harvesting IoE system featuring nonvolatile logics and processing-in-memory (2017)

An energy-efficient nonvolatile intelligent processor (NIP) is proposed for battery-less energy harvesting system. This NIP employs RRAM-based nonvolatile logics (NVL) with self-write-termination (SWT) scheme and low-power processing-in-memory (PIM) to achieve energy-efficient computing against frequent power-off situations. An NIP test chip was fabricated in 150nm CMOS process using HfO RRAM. This NIP chip achieves 462GOPs/J energy efficiency at 20MHz clock frequency, showing 13× performanceimprovement over state-of-the-arts. This work presents the first nonvolatile processor capable of general as well as neural network computing in addition to the first integrated chip using RRAM-based PIM.
Testing stochastic software using pseudo-oracles (2016)

Stochastic models can be difficult to test due to their complexity and randomness, yet their predictions are often used to make important decisions, so they need to be correct. We introduce a new search-based technique for testing implementations of stochastic models by maximising the differences between the implementation and a pseudo-oracle. Our technique reduces testing effort and enables discrepancies to be found that might otherwise be overlooked. We show the technique can identify differences challenging for humans to observe, and use it to help a new user understand implementation differences in a real model of a citrus disease (Huanglongbing) used to inform policy and research.
Dual-Frequency Antenna Design for RFID Application (2006)

With good read range and fast data rate, UHF Ra- dio Frequency Identi¯cation (RFID) is deployed in the supply chain to identify each item uniquely. However, UHF transmission power is easily absorbed by liquids, such as water. Hence, normally, in a environment with lots of liquid products, an HF RFID system is cho- sen instead. This paper investigates the feasibility in designing a dual-frequency (HF and UHF) RFID an- tenna, with frequency ratio of up to 70, to embrace the bene¯ts o®ered by both the UHF and HF RFID systems. Also, this paper shows that with careful de- sign, a single feed dual-frequency RFID antenna can be achieved. A prototype of the dual-frequency RFID an- tenna is presented in this paper, with valid simulation and measurement results.

Improving cache locality for thread-level speculation (2006)

With the advent of chip-multiprocessors (CMPs), thread-level speculation (TLS) remains a promising technique for exploiting this highly multithreaded hardware to improve the performance of an individual program. However, with such speculatively-parallel execution the cache locality once enjoyed by the original uniprocessor execution is significantly disrupted: for TLS execution on a four-processor CMP, we find that the data-cache miss rates are nearly four-times those of the uniprocessor case, even though TLS execution utilizes four private data caches (i.e., four-fold greater cache capacity). We break down the TLS cache locality problem into instruction and data cache, execution stages, and parallel access patterns, and propose methods to improve cache locality in each of these areas. We find that for parallel regions across 13 SPECint applications our simple and low-cost techniques reduce data-cache misses by 38%, improve performance by 12.8%, and significantly improve scalability - further enhancing the feasibility of TLS as a way to capitalize on future CMPs.
Combination of Object Detection and Path Planning Using the Environmental Information for Bin-picking. (1999)

This proposed bin-picking method removes the inconsistency in the information transferred from object detection to path planning of manipulator by using environmental information. The inconsistency is that the object detection only provides the position and orientation of a few detected objects while the path planning needs the environmental information including all objects in the work field. To solve this problem, we propose to include possible objects representing undetected objects in the environmental information. A Hough transform, which records the model-to-image matches in a parameter space, is used to estimate the pose. Both detected and possible objects are extracted from the parameter space. To reduce the number of detection errors and the object-detection time, a pair of object features that reduces the number of invalid votes in the parameter space is used for the Hough transform. Simulated path planning and an experiment on casting objects using a range finder and a manipulator showed that the environmental information including the possible objects improves the ability to plan a safe path for the manipulator. Simulated object detection and an experiment showed that using a pair of features makes the process faster and reduces the number of invalid votes.
Ten Million Data Points from TSO-Approved Aviation GPS Receivers: Results of Analysis and Applications to Design and Use in Aviation (2000)

ABSTRACT: This paper gives details of the failure rates and the failure modes experienced with Standard Positioning Service (SPS) GPS receivers certificated for aviation use to the Technical Standard Order (TSO) C-129 specification. These failure rates are significant compared with those from other modern avionics and are comparable to those currently experienced from unscheduled failures in the GPS signals-in-space. The paper also gives details concerning the two-dimensional errors that have been experienced with these receivers and indicates further work that needs to be done with C-129a receivers.
Synthetic Studies in the Intramolecular Carbocyclization of <i>N</i>-Acyloxyiminium Ions. Stereoelectronic and Steric Implications of Nucleophilic Alkene, Alkyne, and Allene Tethers (2005)

N-Acyloxyiminium ions generated from 4-substituted l-pyroglutamic esters with 4-(3-butenyl), 4-(3-butynyl), 4-(3-cinnamylmethyl), and 4-allenic tethers undergo rapid Lewis acid mediated carbocyclization to give stereodefined azacyclic compounds depending on the nature of the nucleophilic tether. In general, reactions of alkenes and alkynes with terminal alkyl or aryl substituents, as well as allenes, proceed through transient vinylic carbocations that are attacked internally by the N-Boc group to give tricyclic dihydrooxazinones. Diastereotopic bis-4-(3-butenyl) and 4-(3-butynyl) tethers undergo stereochemically controlled attack favoring an antiperiplanar rather than synclinal approach to give enantiopure 6-halo octahydroindole-2-carboxylic acids and 6-halo hexahydroindole-2-carboxylic acids as their methyl esters, respectively. The aza bicyclic and tricyclic compounds are excellent scaffolds for diversification.
Features of Achievement systems (2013)

Achievements and Achievement systems are recognized as important elements to increasing the profitability and success of games titles. Achievements can influence a player's buying decisions and can even increase a player's motivation to continue playing a game. Despite their growing importance to game players, designers, and promoters, little attention has been paid to them by the academic community. In order to better understand these games elements, there exists a need to better understand Achievement Systems, their features and the opportunities offered by them. To this end, this paper will consolidate current knowledge and provide an overview of the features of today's Achievement Systems, exploring the common features of the most popular systems and highlighting points of differentiation designed to better engage players and increase distributor revenue.
Networked Acoustic Sensor Array's Performance During 2004 Horizontal Fusion - Warrior's Edge Demonstration (2004)

As the Army transforms to the Future Force, particular attention must be paid to operations in Complex and Urban Terrain. because our adversaries realize that we don't have battlefield dominance in the urban environment, and because population growth and migration to urban environments is still on the increase, our adversaries will continue to draw us into operations in the urban environment. The Army Research Laboratory (ARL) is developing technology to equip our soldiers for the urban operations of the future. Sophisticated small robotic platforms with diverse sensor suites will be an integral part of the Future Force, and must be able to collaborate not only amongst themselves but also with their manned partners. ARL has developed a Reconnaissance, Surveillance, and Target Acquisition (RSTA) sensor payload for integration onto small robotic vehicles (Packbots), larger robotic scout vehicles (M-Gators), manned soldier transports (ATVs), and on a tethered aerial platform (aerostat). The RSTA sensor payload is equipped with an acoustic array that will detect and localize on an impulsive noise event, such as a sniper's weapon firing. Additionally, the robot sensor head is equipped with visible and thermal camera for operations both day and night. The Packbot can be deployed from the soldier's ATV to enhance their situational awareness in the urban environment, while keeping them out of harms way. The information from one Packbot can then be fused with other sensors as part of a sensor network. Sensor equipped mobile platforms provide an awesome capability to the future dismounted infantry soldier during warfighting and peacekeeping operations in complex and urban terrain by enhancing their situational awareness and improving their survivability. ARL demonstrated networked acoustic detection and localization of mortar, sniper fire, gunfight, and vehicle tracking at the August 11, 2004 Horizontal Fusion - Warrior's Edge (WE) demonstration at the at Fort Benning, Ge7
Degradation of Membrane-bound Ganglioside GM2 by β-Hexosaminidase A (2001)

According to a recent hypothesis, glycosphingolipids originating from the plasma membrane are degraded in the acidic compartments of the cell as components of intraendosomal and intralysosomal vesicles and structures. Since most previous in vitro investigations used micellar ganglioside GM2 as substrate, we studied the degradation of membrane-bound ganglioside GM2 by water-soluble beta-hexosaminidase A in the presence of the GM2 activator protein in a detergent-free, liposomal assay system. Our results show that anionic lipids such as the lysosomal components bis(monoacylglycero)phosphate or phosphatidylinositol stimulate the degradation of GM2 by beta-hexosaminidase A up to 180-fold in the presence of GM2 activator protein. In contrast, the degradation rate of GM2 incorporated into liposomes composed of neutral lysosomal lipids such as dolichol, cholesterol, or phosphatidylcholine was significantly lower than in negatively charged liposomes. This demonstrates that both, the GM2 activator protein and anionic lysosomal phospholipids, are needed to achieve a significant degradation of membrane-bound GM2 under physiological conditions. The interaction of GM2 activator protein with immobilized membranes was studied with surface plasmon resonance spectroscopy at an acidic pH value as it occurs in the lysosomes. Increasing the concentration of bis(monoacylglycero)phosphate in immobilized liposomes led to a significant drop of the resonance signal in the presence of GM2 activator protein. This suggests that in the presence of bis(monoacylglycero)phosphate, which has been shown to occur in inner membranes of the acidic compartment, GM2 activator protein is able to solubilize lipids from the surface of immobilized membrane structures.
Personalization of Hyperlinked Video in Interactive Television (2005)

The GMF4iTV project is building an end-to-end broadcast system for providing interactivity to TV programs through active video objects. This paper describes the personalization scheme that has been defined and implemented in this project. On the authoring side, an interface tool allows the video producers to annotate both objects and associated additional content, with attributes from different ontologies. On the receiver side, a personalization engine compares these attributes with the user profile to personalize the interaction with the user. We describe the various components of the system and provide some application examples.
Aperiodic phase re‐setting in scalp EEG of beta–gamma oscillations by state transitions at alpha–theta rates (2003)

We evaluated the rapid changes in regional scalp EEG synchronization in normal subjects with spatial and temporal resolution exceeding prior art 10-fold with a high spatial density array and the Hilbert transform. A curvilinear array of 64 electrodes 3 mm apart extending 18.9 cm across the scalp was used to record EEG at 200/sec. Analytic amplitude (AA) and phase (AP) were calculated at each time step for the 64 traces in the analog pass band of 0.5-120 Hz. AP differences approximated the AP derivative (instantaneous frequency). The AP from unfiltered EEG revealed no reproducible patterns. Filtering was necessary in the beta and gamma ranges according to a technique that optimized the correlation of the AP differences with the activity band pass filtered in the alpha range. The sizes of temporal AP differences were usually within +/-0.5 radian from the average step corresponding to the center frequency of the pass band. Large AP differences were often synchronized over distances of 6 to 19 cm. An optimal pass band to detect and measure these recurring jumps in AP in the beta and gamma ranges was found by maximizing the alpha peak in the cospectrum of the correlation between unfiltered EEG and the band pass AP differences. Synchronized AP jumps recurred in clusters (CAP) at alpha and theta rates in resting subjects and with EMG. Cortex functions by serial changes in state. The Hilbert transform of EEG from high-density arrays can visualize these state transitions with high temporal and spatial resolution and should be useful in relating EEG to cognition.
Improving 3D image quality of x-ray C-arm imaging systems by using properly designed pose determination systems for calibrating the projection geometry (2003)

C-arm volume reconstruction has become increasingly popular over the last years. These imaging systems generate 3D data sets for various interventional procedures such as endovascular treatment of aneurysms or orthopedic applications. Due to their open design and mechanical instability, C-arm imaging systems acquire projections along non-ideal scan trajectories. Volume reconstruction from filtered 2D X-ray projections requires a very precise knowledge of the imaging geometry. We show that the 3D image quality of C-arm cone beam imaging devices can be improved by proper design of the calibration phantom.

Streptococcal Toxic Shock Syndrome: Synthesis of Tumor Necrosis Factor and Interleukin-1 by Monocytes Stimulated with Pyrogenic Exotoxin A and Streptolysin O (1992)

Previous studies have found that 80% of strains isolated from patients with the streptococcal toxic shock syndrome produce pyrogenic exotoxin A (SPEA) and 100% produced streptolysin O (SLO). To elucidate the cellular mechanisms contributing to shock, human monocytes were stimulated with SPEA (0.1-10 micrograms/10(6) monocytes) or SLO (0.2-2.5 hemolytic units/10(6) monocytes), and production of tumor necrosis factor (TNF)-alpha and interleukin (IL)-1 beta was measured at 24, 48, and 72 h. SPEA and SLO were potent inducers of TNF alpha, with maximum production occurring at 72 h for SPEA and at 48 h for SLO (1067 and 687 pg/ml, respectively). In contrast, IL-1 beta production was greater for SLO than for SPEA (557 vs. 258 pg/ml). In addition, the effects of SPEA and SLO together were synergistic in terms of monocyte IL-1 beta production: SPEA, 193 pg/ml; SLO, 452 pg/ml; SPEA plus SLO, 799 pg/ml. These findings suggest TNF alpha and IL-1 beta are important candidates for mediating shock in severe streptococcal infections.
Adaptive Listen-Before-Talk (LBT) scheme for LTE and Wi-Fi systems coexisting in unlicensed band (2016)

Listen-Before-Talk (LBT) protocol is an essential mechanism that allows Wi-Fi and LTE systems to share the unlicensed band while maintaining the performance of each individual system. However, a conventional LBT mechanism in this coexisting environment operates with the fixed channel occupancy time (COT) even under the varying traffic load in each system. In practice, if COT is set too short or large, one of two systems becomes inefficient when it is overloaded. Furthermore, Wi-Fi and LTE systems operate with different back-off mechanisms, which may violate the requirement of fair-coexistence. It implies that the operational parameters in LBT protocol must be dynamically adapted to the varying traffic load and back-off window size of Wi-Fi system. Toward this end, we propose an adaptive LBT protocol that can increase the overall system throughput without compromising a performance of the Wi-Fi system in the coexisting environment. Two different adaptation mechanisms, on-off adaptation for COT of LTE system and short-long adaptation for idle time (IT), are designed to implement the adaptive LBT scheme. Our simulation results demonstrate that the overall system throughput can be improved by 30–105% depending on the traffic load, while warranting the performance of the Wi-Fi system.

The combination of these 15 lipid species as a panel could be used as plasma biomarkers for the diagnosis of breast cancer.
Cell Volume Regulation in Lymphocytes (1988)

This article reviews what is known about the volume regulatory responses of lymphocytes. We present a discussion of recent data and hypotheses pertaining to the underlying mechanisms in regulatory volume increase (RVI) and regulatory volume decrease (RVD). New results from our laboratory are included to demonstrate that RVD is modulated by both temperature and pH, and that RVD occurs in proliferating as well as quiescent lymphocytes. This information is considered in the context of a model that includes the dynamics of membrane potential, K+ conductance. Cl- conductance, a proposed stretch-activated conductance, gating mechanisms, and equilibrium potentials, as RVD progresses. The physiological relevance of volume homeostasis in lymphocyte function, in particular, and in cell growth and proliferation, in general, is discussed.
Design of an On-Chip Reflectance Map (1995)

A reflectance map design is described which uses a minimal amount of memory for the table, in order to be applicable as an on-chip shader. The shader is designed for use with the volumetric super resolution hardware, which performs shading at supersampled locations. However, the design may be used as well to support surface visualization applications. Despite the small table size, the image quality obtained is excellent, even on smooth surfaces.
