Tracking across nonoverlapping cameras based on the unsupervised learning of camera link models (2012)

A multiple-camera tracking system that tracks the human across cameras with nonoverlapping views is proposed. The system is divided into two phases. In the training stage, the camera link model, including transition time distribution, brightness transfer function, region mapping matrix, region matching weight, and feature fusion weight, is estimated by an unsupervised learning scheme which tolerates well the presence of outliers in the training data. In the testing stage, besides the temporal and holistic color features, region color and region texture features are considered. The systematically integration of multiple cues enables us to perform the effective re-identification. The camera link model keeps being updated during the tracking in order to adapt the change of the environment. The complete system has been tested in a real-world camera network scenarios.
Powerful change part 2: reducing the power demands of mobile devices (2004)

Consumers expect their mobile devices to be small and light, have a decent battery lifetime, and still be powerful enough to run all their desired applications. The need to satisfy such consumer demands has driven mobile-device manufacturers to make products (such as PDAs and cell phones) that match these needs. However, this inevitably requires tradeoffs. Building smaller, lighter devices requires sacrificing the device's battery capacity because battery technology is still fairly dense and heavy, and contributes most of a mobile device's size and weight. But, mobile devices with the required resources to run useful desktop applications need additional battery power to run those resources for a reasonable length of time. Because the tension facing manufacturers appears to be in deciding the battery-weight and battery-performance tradeoffs, the solution seems to lie in finding ways to increase a mobile device's battery lifetime.
Feasibility of using impedance‐based damage assessment for pipeline structures (2001)

Abstract This paper presents the feasibility of using an impedance‐based health monitoring technique in monitoring a critical civil facility. The objective of this research is to utilize the capability of the impedance method in identifying structural damage in those areas where a very quick condition monitoring is urgently needed, such as in a post‐earthquake analysis of a pipeline system. The basic principle behind this technique is to utilize high‐frequency structural excitation (typically greater than 30 kHz) through surface‐bonded piezoelectric sensors/actuators to detect changes in structural point impedance due to the presence of damage. Real‐time damage detection in pipes connected by bolted joints was investigated, and the capability of the impedance method in tracking and monitoring the integrity of the typical civil facility has been demonstrated. Data collected from the tests illustrates the capability of this technology to detect imminent damage under normal operating conditions and immediately after a natural disaster.

"Odour patris tu" (my father's smell) (2017)

This creative-led research extends on my ongoing investigation on how ephemeral materials can provide insight into mortality; and the role that art can play in mediating issues of life and death. The exhibition displays a series of perfumed toiletries that represent a signature fragrance of a deceased family member. As a highly nuanced sense, with an enormous capacity to trigger human emotions, it is surprising that smell features so rarely in aesthetics. This research redresses this by using wind up deodorant sticks, and talcum powder as art materials to create personal talismans that speak to the power of smell to evoke memories; build an intimate portrait of the subject behind the aroma; and explore the cultural dimensions of smell and its function as a medium of self-definition.
Strained Si<sub>1-x</sub>Ge<sub>x</sub>/Si Dots and Wires Grown by Selective Epitaxy (1995)

Selective epitaxial growth of Si1-xGex was studied with the aim to fabricate quantum wires and dots. The selective deposition was performed by low pressure chemicd vapor deposition with dichlorosilane and germane as precursors, at 0.1 Torr and 700°C in a radiation heated, cold wall, high vacuum, quartz reactor. Dislocation free strained dots and wires could be grown much thicker than the critical thickness for unpatterned area, because the critical thickness by formation of misfit dislocations increases when the window dimension is reduced. For x up to 20% it was found that for 10x10µm2 dots the critical thickness increases by more than 4 times. The tendency of facet formation was exploited to realize laterally confined multiple quantum well dots and wires with size down to 50 nm. Besides the emission from the (100) quantum well layers excintonic emissions from quantum well layers from flat {110} facets and from islands in the (100) and {311}facets were detected. All dots and wires luminecse stronly down to the lowest achieved dimension of 50 nm, the integral intensity exceeding that from the substrate.
Randomised controlled trials and health services research (1995)

Evaluation of palliative careRecruitment figures may be low EDrroR,-In response to the paper by Ian R McWhinney and colleagues' we wish to report our experience of recruitment into trials in the palliative care setting.The trials were not of a palliative care service but of palliative therapeutic interventions in a specialist cancer hospital.These included randomised studies of pharmacological and non-pharmacological strategies in the manage- ment of bowel obstruction, hypercalcaemia, nausea induced by opiates, anorexia, pain, and dyspnoea as well as non-randomised studies in patients in pain.In the 12 months to October 1994, 344 patients were referred to one of two research sisters in palliative care as being suitable for entry to one of the above studies.Both inpatients and outpatients were referred by medical and nursing staff throughout the hospital.Of the 344 patients, 109 were not approached as they did not fulfil the criteria for inclusion in the studies.Thus after full discussion regarding the implications of entering the trial 235 patients were asked if they would agree to participate in one of the studies.Only 142 patients gave informed consent.The remainder were not entered into the studies because they were too unwell or their condition had deteriorated (27), they were eligible but declined to consent (38), they lived too far away from the hospital ( 16), or for unknown reasons (12).Thus 41% of the patients initially referred and 60% of the patients who were approached were entered into studies.These figures are low but are likely to be higher than those achieved in other palliative care settings since the patients were recruited in a specialist cancer hospital with a high research profile, where the role of the research sister is well established.We agree with Henry McQuay and Andrew Moore that palliative care should not be excused from conducting randomised controlled trials simply because they are difficult to do,2 but our recruitment data show several of the inherent difficulties.
Plasma‐Enhanced Chemical Vapor Deposition of Silicon Dioxide Using Tetraethylorthosilicate (TEOS) (1989)

This paper presents a study on plasma‐assisted chemical vapor deposition of silicon dioxide films using tetraethylorthosilicate (TEOS). It was found that when oxygen is utilized as an oxidant, the resulting film contained approximately 1 atom percent (a/o) of nitrogen or carbon, whereas using in the reaction slightly increased the nitrogen concentration to 2 a/o. However, in the absence of oxidant, the carbon and nitrogen concentrations were approximately 18 and 6 a/o, respectively. The step coverage of the film, regardless of the oxidant, was approximately 34%, a substantial improvement compared to the 10% obtained for oxide films deposited using silane‐based chemistry. The refractive index, infrared spectrum, and film density appear characteristic of deposited films. The electrical characterization of the films yielded a breakdown electric field greater than 6.6 MV/cm, and a leakage current density of at 1 MV/cm. The breakdown electric field and leakage current density of a thermally grown oxide with comparable thickness are 8 MV/cm and , respectively.
Compliant coordination control of two moving industrial robots (1990)

When two robots execute coordinated motion in industrial application such as assembly, not only is the specification of the desired motion of each robot's end effector required, but also that of the desired contact force exerted on the end effectors. The involvement of the forces is the motivation for a consideration of compliance. The compliant coordination control scheme of two moving robots is presented. One robot is equipped with a force/torque sensing wrist, which provides force feedback signals and permits the fine coordinated motion control of complex assembly tasks. A control strategy is derived so that the measured force/torque can be used to modify the trajectory of one of the robots. This control scheme can be realized in real time by using the proposed computational structure. The system stability is related to the force-displacement conversion gain in the forward path. An experiment that screws a moving nut onto a moving bolt has been carried out as an illustration.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Acid ceramidase is upregulated in AML and represents a novel therapeutic target (2016)

There is an urgent unmet need for new therapeutics in acute myeloid leukemia (AML) as standard therapy has not changed in the past three decades and outcome remains poor for most patients. Sphingolipid dysregulation through decreased ceramide levels and elevated sphingosine 1-phosphate (S1P) promotes cancer cell growth and survival. Acid ceramidase (AC) catalyzes ceramide breakdown to sphingosine, the precursor for S1P. We report for the first time that AC is required for AML blast survival. Transcriptome analysis and enzymatic assay show that primary AML cells have high levels of AC expression and activity. Treatment of patient samples and cell lines with AC inhibitor LCL204 reduced viability and induced apoptosis. AC overexpression increased the expression of anti-apoptotic Mcl-1, significantly increased S1P and decreased ceramide. Conversely, LCL204 induced ceramide accumulation and decreased Mcl-1 through post-translational mechanisms. LCL204 treatment significantly increased overall survival of C57BL/6 mice engrafted with leukemic C1498 cells and significantly decreased leukemic burden in NSG mice engrafted with primary human AML cells. Collectively, these studies demonstrate that AC plays a critical role in AML survival through regulation of both sphingolipid levels and Mcl-1. We propose that AC warrants further exploration as a novel therapeutic target in AML.
Read Refresh Scheduling and Data Reallocation against Read Disturb in SSDs (2022)

Read disturb is a circuit-level noise in flash-based Solid-State Drives (SSDs), induced by intensive read requests, which may result in unexpected read errors. The approach of read refresh (RR) is commonly adopted to mitigate its negative effects by unconditionally migrating all valid data pages in the RR block to another new block. However, routine RR operations greatly impact the I/O responsiveness of SSDs, because the processing on normal I/O requests must be blocked at the same time. To further reduce the negative effects of read refresh, this article proposes a read refresh scheduling and data reallocation method to deal with two primary issues with respect to an RR operation, including where to place data pages and when to trigger page migrations. Specifically, we first construct a data reallocation model to match the data pages in the RR block and the destination blocks for addressing the issue of where to place the data. The model considers not only the read hotness of pages in the RR block, but also the accumulated read counts of the destination blocks. Moreover, for addressing the issue of when to trigger data migrations, we build a timing decision model to determine the time points for completing page migrations by considering the factors of the intensity of I/Os and the disturb situation on the RR block. Through a series of simulation experiments based on several realistic disk traces, we illustrate that the proposed RR scheduling and data reallocation mechanism can noticeably reduce the read errors by more than 10.3% , on average, and the long-tail latency by between 43.9% and 64.0% at the 99.99th percentile, in contrast to state-of-the-art methods.
A Computational Tool for Quantitative Analysis of Vascular Networks (2011)

Angiogenesis is the generation of mature vascular networks from pre-existing vessels. Angiogenesis is crucial during the organism' development, for wound healing and for the female reproductive cycle. Several murine experimental systems are well suited for studying developmental and pathological angiogenesis. They include the embryonic hindbrain, the post-natal retina and allantois explants. In these systems vascular networks are visualised by appropriate staining procedures followed by microscopical analysis. Nevertheless, quantitative assessment of angiogenesis is hampered by the lack of readily available, standardized metrics and software analysis tools. Non-automated protocols are being used widely and they are, in general, time--and labour intensive, prone to human error and do not permit computation of complex spatial metrics. We have developed a light-weight, user friendly software, AngioTool, which allows for quick, hands-off and reproducible quantification of vascular networks in microscopic images. AngioTool computes several morphological and spatial parameters including the area covered by a vascular network, the number of vessels, vessel length, vascular density and lacunarity. In addition, AngioTool calculates the so-called "branching index" (branch points/unit area), providing a measurement of the sprouting activity of a specimen of interest. We have validated AngioTool using images of embryonic murine hindbrains, post-natal retinas and allantois explants. AngioTool is open source and can be downloaded free of charge.
Measurement of Magnetic Properties of Grain-Oriented Electrical Steel Sheet Using 2D Single Sheet Tester (2011)

We have already reported the accuracy of measurement of 2D magnetic properties of non-oriented electrical steel sheet using a novel SST. In this paper, magnetic properties under alternating and rotating magnetic flux of grain-oriented sheet are measured. The accuracy of measurement in the case of grain-oriented sheet is examined by comparing the measured results using 2D-SST with those using an ordinary SST under alternating flux excitation. The effect of positioning error of orthogonal B and H coils on measurement accuracy is also discussed. Streszczenie.

Endcapping Treatment of Inner Surfaces of a Hexagonal Mesoporous Silica (2012)

Abstract The inner surfaces of a hexagonal mesoporous silica (HMS) are treated by chlorotrimethylsilane, either directly or through vapor or liquid endcapping. The directly treated inner surfaces have the highest effective interfacial tension, and the liquid endcapping treated surfaces have the largest accessible nanopore volume. The difference in the treatment results may be attributed to the distinct surface structures.
ID-based one round authenticated group key agreement protocol with bilinear pairings (2005)

Authenticated group key agreement is important in many modern collaborative and distributed applications. Recently, identity-based authenticated group key agreement has been increasingly researched because of the simplicity of a public key management. Basically, these protocols provide authentication by signatures. Hence they are less efficient for the verification of signatures creates additional computational overhead. In the paper, we propose an efficient authenticated group key agreement protocol by introducing a modified identity-based public key infrastructure with new system setup and key extraction algorithms. The security of our protocol is assured by the discrete logarithm assumption. Moreover, our protocol requires only one round and is more efficient than all previously known ones since it provides authentication without using signatures.
Advances in telemetric continuous intraocular pressure assessment (2009)

With an ageing population showing an increasing prevalence of glaucoma, there is a pressing demand for continuous intraocular pressure (IOP) measurements which could surpass clinic-based measurements such as routine applanation tonometry. Glaucoma patients have fluctuations in IOP, and it has been proposed that these fluctuations are relevant to glaucoma progression. In addition, interindividual and intraindividual variation in corneal thickness and rigidity can lead to significant and poorly quantitated errors in applanation-based methods of estimating IOP. Microelectrical mechanical systems and complementary metal oxide semiconductor-based technology has enabled the development of smart miniaturised devices by augmenting the computational ability of microelectronics with capabilities of microsensors and microactuators. This review addresses various sensor technologies and both invasive and non-invasive approaches to the measurement of IOP. Advances in wireless communication (telemetry) between the implanted sensors and the external readout device are reviewed. In addition, biocompatibility of implantable sensors is discussed.
Perspective: Ga2O3 for ultra-high power rectifiers and MOSFETS (2018)

Gallium oxide (Ga2O3) is emerging as a viable candidate for certain classes of power electronics with capabilities beyond existing technologies due to its large bandgap, controllable doping, and the availability of large diameter, relatively inexpensive substrates. These applications include power conditioning systems, including pulsed power for avionics and electric ships, solid-state drivers for heavy electric motors, and advanced power management and control electronics. Wide bandgap (WBG) power devices offer potential savings in both energy and cost. However, converters powered by WBG devices require innovation at all levels, entailing changes to system design, circuit architecture, qualification metrics, and even market models. The performance of high voltage rectifiers and enhancement-mode metal-oxide field effect transistors benefits from the larger critical electric field of β-Ga2O3 relative to either SiC or GaN. Reverse breakdown voltages of over 2 kV for β-Ga2O3 have been reported, either with or without edge termination and over 3 kV for a lateral field-plated Ga2O3 Schottky diode on sapphire. The metal-oxide-semiconductor field-effect transistors fabricated on Ga2O3 to date have predominantly been depletion (d-mode) devices, with a few demonstrations of enhancement (e-mode) operation. While these results are promising, what are the limitations of this technology and what needs to occur for it to play a role alongside the more mature SiC and GaN power device technologies? The low thermal conductivity might be mitigated by transferring devices to another substrate or thinning down the substrate and using a heatsink as well as top-side heat extraction. We give a perspective on the materials’ properties and physics of transport, thermal conduction, doping capabilities, and device design that summarizes the current limitations and future areas of development. A key requirement is continued interest from military electronics development agencies. The history of the power electronics device field has shown that new technologies appear roughly every 10-12 years, with a cycle of performance evolution and optimization. The older technologies, however, survive long into the marketplace, for various reasons. Ga2O3 may supplement SiC and GaN, but is not expected to replace them.
An ameliorated methodology for the design of panoptic work process flow diagram (2016)

UML is the only language which clearly distinguishes a higher level design and lower level design diagrams. While designing UML diagrams, the same semantics can be implemented with different pragmatics. This created the commotion in the SDLC design stages. This commotion leads to the gorge between the higher level and lower level designs. This is resolved by the redesign of new higher level diagrams those constellate the lower level diagrams to maintain the balustrade ordered pan-tile sequel of SDLC stages. The precise study of DFD reveals that though DFD represents the behavioral aspect extrinsically, it intrinsically represent the structural flow. On the other hand CD represents the structural information extrinsically, intrinsically it represents behavioral aspect. Thus individually, both diagrams are panoptic complements to each other. So each perse cannot completely give either structural or behavioral aspect of the project. However, if both are superposed each other, it gives both together completely the behavioral and structural aspect of the project. Hence, in our paper DFD and CD are used to design the higher level diagram semiotics to resurrect the SDLC stages.
An autonomous module for supporting mice during spaceflight. (1995)

The Animal Module for Autonomous space Support (A-MASS) was developed to enable 30-day spaceflight for mice on the first Commercial Experiment Transporter mission. Because space hardware did not previously exist to support mice without astronaut intervention, the A-MASS presented considerable technical and animal care challenges. The technical challenges included maintaining a 42.5l payload volume and 20-g structural conformance while providing 30 days of autonomous mouse support. Sensors, video, a pressurized oxygen supply system and an internal data logging system were incorporated. The A-MASS met NIH guidelines for temperature, humidity, food and water access, oxygen supply, air quality and odor control. These technical and animal care challenges, along with power and mass constraints, were addressed using a novel design which ensures a fresh food and water supply, a clean view path into the cage for the camera system, and removal of the wastes from the air supply. The payload was successfully tested in an enclosed chamber and passed animal health, vibrational, mechanical, and electrical tests. The physiological, tactical and animal support information gathered will be applicable to the development of mouse support modules for the Shuttle Middeck and Space Station Freedom Express Rack environments.
Evidence for a Gene-Environment Interaction in Predicting Behavioral Inhibition in Middle Childhood (2005)

Gene-environment interactions are presumed to shape human behavior during early development. However, no human research has demonstrated that such interactions lead to stable individual differences in fear responses. We tested this possibility by focusing on a polymorphism in the promoter region of the gene for the serotonin transporter (5-HTT). This polymorphism has been linked to many indices of serotonin activity. Specifically, we tested the hypothesis that an interaction between children's 5-HTT status and maternal reports of social support predicts inhibited behavior with unfamiliar peers in middle childhood. Results were consistent with this hypothesis: Children with the combination of the short 5-HTT allele and low social support had increased risk for behavioral inhibition in middle childhood.
