Quality-Based Multiple-Sensor Fusion in an Industrial Wireless Sensor Network for MCM (2014)

The early alert monitoring system for an effective scheduled maintenance strategy based on a wireless technology requires reliable transfer of the diagnostic information between the sensor and the gateway. This paper presents an industrial wireless sensor network (IWSN)-based machine condition monitoring (MCM) system capable of overcoming a false indication caused by temporary loss of data, signal interference, or invalid data. We use multisensor fusion driven by a quality parameter, which is produced by each sensor node according to the data history outliers and the actual state of the node. The fusion node provides a quality evaluation on its output as well. This novel approach enables the propagation of information about the uncertainty of a measured value from the source node to the sink node. Thus, potential degradation of acquired or transferred diagnostic information is minimized. Instead of raw data, the signal features are transferred, so that bandwidth savings are rapidly improved. The proposed concept was experimentally verified on real wireless sensor network (WSN) hardware. The performance evaluated using the signal-to-noise ratio and false-alarm rate detection demonstrates the effectiveness of the proposed approach.
Virtual machine auto-configuration for web application (2010)

With the booming trend of cloud computing, on-demand resource management is overwhelming static and dedicated strategy. The increasing demands introduce multiple challenges including energy efficiency, performance enhancement, and fault tolerance. Virtualized computing environment decouples OS and applications with hardware to best facilitate these on-demand cloud services. In this paper, we propose an online learning approach for resource auto-configuration of distributed virtual machines to support multilayer web applications. Based on performance metrics from host OS, virtual machine, and application server, the approach is able to adjust resource configuration and direct virtual machine migration corresponding to service demand variations. Support vector regression is applied to control reconfiguration and migration. The approach will be evaluated by using TPC-E benchmark on multi-layer web applications deployed on networked virtual machines. Our approach will guide systems with proactive changes to improve dependability, efficiency, and reduce the power consumption.
Wireless Source Localization and Signal Collection from an Airborne Symmetric Line Array Sensor Network (2014)

Wireless communication technology has become a critical aspect in many civilian and military applications. With regard to remote sensing, search and rescue, disaster relief operations and signals intelligence, there exists an interest in developing capabilities to collect these signals-of-interest. The objective of this dissertation is to maximize signal collection performance in the presence of signal measurement and sensor related errors. To accomplish this objective, we proposed a signal collection scheme that exploits an elevated, mobile network to maximize the collaborative collection of a target signal. The proposed scheme begins with source localization. This technique consists of an initial weighted least-squares estimate followed by a maximum-likelihood estimate. Implemented on an elevated, mobile network, this technique is able to obtain an optimal localization. To enhance localization robustness, we developed an outlier rejection process that mitigates the effects of measurement and sensor position errors. To collect the signal, this research quantified the effects of sensor position errors on beamforming and proposed a novel signal collection scheme that combines signal estimation and collaborative beamforming. Using all these techniques in concert, we were able to show that the proposed scheme outperforms standard collaborative beamforming in the presence of sensor position errors.
Nomad - an Aircraft to Meet the Changing Needs of Society (1982)

The Nomad is a twin-engined STOL aircraft designed and developed by the Australian Government Aircraft Factories, Melbourne. Designed originally for the Australian Army and for aerial work, it has been developed to carry 16 passengers for commuter-type airline operations and to carry sophisticated radar and navigational systems for maritime surveillance. Its fuel economy makes it attractive to commuter operators and its economy in surveillance operations has led to its use by the Australian Departments of Transport and Customs along the northern and north-eastern coastlines of Australia and for patrolling the 200 mile Exclusive Economic Zone.
Antibiotic Susceptibility and Resistance Testing: An Overview (2000)

The results of in vitro antibiotic susceptibility testing can predict the clinical response to treatment and guide the selection of antibiotics. The minimum inhibitory concentration (MIC) of an organism is the lowest concentration of an antibiotic that will inhibit its growth. Bacteria are classified as sensitive, intermediate or resistant based on breakpoint MIC values that are arbitrarily defined and reflect the achievable levels of the antibiotic, the distribution of MICs for the organism and their correlation with clinical outcome. Broth dilution, agar dilution and gradient diffusion (the 'E test'), where twofold serial dilutions of antibiotic are incorporated into tubes of broth, agar plates or on a paper strip, respectively, are different methods to measure the MIC of an organism. The disk diffusion method defines an organism as sensitive or resistant based on the extent of its growth around an antibiotic-containing disk. MIC values are influenced by several laboratory factors. To ensure reproducible results, the laboratory must closely follow methods developed by the National Committee for Clinical Laboratory Standards, which defines standard growth media, incubation temperature and environment, the inoculum and quality control parameters.

Kinetic dependence of phospholipase A2 activity on the detergent Triton X-100 (1973)

A kinetic analysis is presented for the dependence of one form of phospholipase A(2) from cobra (Naja naja) venom on the presence of the nonionic detergent Triton X-100 for its activity towards egg phosphatidylcholine and synthetic dipalmitoyl glycerophosphorylcholine as substrates. An automatic recording pH-stat apparatus was employed in order to continuously monitor enzyme activity. The results obtained in this study are interpreted in terms of a change in the physical state of the phospholipid when Triton X-100 micelles convert phospholipid bilayers into mixed Triton X-100-phospholipid micelles; this is consistent with the requirement of this enzyme for substrates which are in micellar form rather than either monomers or bilayers. An apparent inhibition of phospholipase A(2) activity at high concentrations of Triton X-100 is described and discussed in terms of the micellar nature of the substrate.
Sticky Traps for Sampling Populations of Stomoxys calcitrans12 (1973)

Sticky panel traps were more than 7 times as effective in collecting stable flies along beaches in NW Florida than previously used box traps. Translucent white was the most effective of 3 tested colors. Stable flies were collected in greater numbers on the leeward side of the traps, and usually the highest concentration collected on any individual trap was along its border.
Visualizing Program Executions on Large Data Sets Using Semantic Zooming (1995)

Understanding and interpreting a large data source is an important but challenging operation in many technical disciplines. Computer visualization has become a valuable tool to help capture and portray characteristics of large data sets. In software visualization, illustrating the operation of very large programs or programs working on very large data sets has remained one of the key open problems. Here, we introduce an approach that uses semantic zooming to depict large program executions. Our method utilizes abstract, clustered graphics to portray program operations on the entire data set. Then, by interacting with the presentation, a viewer can zoom in to examine details and individual values. At this "magnified" level, the presentation adjusts to reflect displays common in existing algorithm animation and program visualization systems.
The G2 development and deployment environment (2003)

G2 is an object-oriented development and deployment environment, combining rule-based and procedural reasoning, user interface graphics, database interface capabilities, dynamic simulation, and real-time execution in a single package. The applications of G2 typically have large knowledge bases, with tens of thousands of objects, and generally real-time execution is required. The online installations span the process industries, discrete manufacturing, aerospace, telecommunications, electric utilities, and others. Primarily these installations have been implemented directly by plant engineers, who have defined the knowledge contained in the applications using G2's structured natural language and active-object graphics. The design of G2 is described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Designing Cold Ironing Power Systems: Electrical Safety During Ship Berthing (2014)

Cold ironing power system design requires unique components to supply shore power to ships for cold ironing operation. Currently, the development of new standards is in progress, and operating procedures are being written to maximize electrical safety, standardization of the process, and interchangeability from one location to another. This article describes the power system design, including a power system protection scheme, which should enhance the electrical safety by design. The power system grounding, equipment grounding, and touch potential that can impact personnel safety are described. A very basic outline of the operating procedures and training needed for the operators to maximize electrical safety during cold ironing operation are also included in this article. In addition, this article provides the current status of the draft International Electrotechnical Commission (IEC)/International Organization for Standardization (ISO)/IE Standards 80005-1 [5] and 80005-2 [6].
Mapping the Gene for Hereditary Cutaneous Malignant Melanoma–Dysplastic Nevus to Chromosome Lp (1989)

We used molecular genetic techniques and multipoint linkage analyses to locate the gene responsible for cutaneous malignant melanoma-dysplastic nevus. We evaluated 99 relatives and 26 spouses in six families with a predisposition to melanoma. Thirty-four family members had cutaneous malignant melanoma, and 31 of these 34 also had histologically confirmed dysplastic nevi. Twenty-four family members had dysplastic nevi alone. An analysis of the cosegregation of the cutaneous malignant melanoma-dysplastic nevus trait with 26 polymorphic DNA markers on the short arm of chromosome 1 demonstrated the presence of a gene for susceptibility to melanoma. The gene was located between an anonymous DNA marker (D1S47) and the gene locus for pronatrodilatin, a commonly used reference gene (PND), in chromosome band 1p36. The odds were greater than 260,000:1 in favor of linkage at this location.
Investigations Into Alternate Spark Gap Switching Techniques (1994)

This report documents the design, operation, and experimental results of the evaluation of a new spark gap triggering method. These spark gaps were developed to support ARL's ongoing nuclear electromagnetic pulse (EMP) current injection assessment programs. This trigger method provides operator control, multiple spark gap control with synchronous triggering, and a limited amount of hardware to control the spark gap triggering. A patent application has been started for this device and has been assigned case number HDL No. 94-3.
Stability and cap formation mechanism of single-walled carbon nanotubes (1998)

We use tight-binding total-energy calculations to investigate the energetics and the cap formation mechanism of single-walled carbon nanotubes. The present calculations of the edge energy and strain energy suggest the growth of armchair nanotubes to be energetically more favorable than the growth of zigzag nanotubes. The cap formation at the edge of both nanotubes is animated by the tight-binding molecular-dynamics simulations. The cap formation is immediately followed by the pentagon formation at the edge of both tubes. The role of transitions metals is further discussed.
Direct Hydrogenation of Biomass‐Derived Butyric Acid to <i>n</i>‐Butanol over a Ruthenium–Tin Bimetallic Catalyst (2014)

Catalytic hydrogenation of organic carboxylic acids and their esters, for example, cellulosic ethanol from fermentation of acetic acid and hydrogenation of ethyl acetate is a promising possibility for future biorefinery concepts. A hybrid conversion process based on selective hydrogenation of butyric acid combined with fermentation of glucose has been developed for producing biobutanol. ZnO-supported Ru-Sn bimetallic catalysts exhibits unprecedentedly superior performance in the vapor-phase hydrogenation of biomass-derived butyric acid to n-butanol (>98% yield) for 3500 h without deactivation.
Nanomaterials as Non-viral siRNA Delivery Agents for Cancer Therapy (2013)

Gene therapy has been recently shown as a promising tool for cancer treatment as nanotechnology-based safe and effective delivery methods are developed. Generally, genes are wrapped up in extremely tiny nanoparticles which could be taken up easily by cancer cells, not to their healthy neighboring cells. Several nanoparticle systems have been investigated primarily to address the problems involved in other methods of gene delivery and observed improved anticancer efficacy suggesting that nanomedicine provides novel opportunities to safely deliver genes, thus treat cancer. In this review, various nanoparticle types and related strategies, used in gene delivery for cancer treatment, have been discussed.
Antithrombin action of phosvitin and other phosphate‐containing polyanions is mediated by heparin cofactor II (1988)

We have examined the antithrombin effects of various phosphate-containing polyanions (including linear polyphosphates, polynucleotides and the phosphoserine glycoprotein, phosvitin) on the glycosaminoglycan-binding plasma proteinase inhibitors, antithrombin III (ATIII) and heparin cofactor II (HCII). These phosphate-containing polyanions accelerate the HCII-thrombin reaction, as much as 1600-fold in the case of phosvitin. The HCII-thrombin reaction with both phosvitin and polynucleotides appears to follow the ternary complex mechanism. The HCII-thrombin complex is rapidly formed in the presence of these phosphate polyanions (each at 10 micrograms/ml) when 125I-labeled thrombin is incubated with human plasma (ex vivo). None of these phosphate polyanions accelerate the ATIII-thrombin reaction. Our results suggest that the antithrombotic effect of these phosphate-containing polyanions is mediated by HCII activation and not by ATIII.

Dopant passivation in AlInAs and InGaP by atomic deuterium (1991)

Shallow dopant passivation in AlInAs and InGaP exposed to low power (0.08 W cm−2) deuterium plasmas was investigated by Hall effect and secondary ion mass spectrometry measurements. The carrier concentration in AlInAs was reduced by factors of 3–4 in both Si- and Zn-doped epitaxial layers upon exposure to a D2 plasma at 200 °C. Substantially greater reductions are observed in Si-doped InGaP (500×reduction) and Be-doped InGaP (15×reduction) under the same conditions. Complete reactivation of all the passivated dopants occurs in the temperature range 350–425 °C for annealing in inert ambients. By contrast, the use of hydrogen containing ambients during post-plasma annealing enhances the apparent stability of the dopant passivation. The diffusivity of deuterium is greater in p-type layers than in n-type layers for each material.
43.2: Low‐Temperature Polycrystalline‐Silicon TFT Color LCD Panel Made of Plastic Substrates (2002)

Abstract An all‐plastic, full‐color LTPS TFT LCD has been fabricated with practical image quality. The diagonal size is 1.5 inch with a panel thickness of only 0.4mm. The TFT layer on a plastic substrate was prepared with a newly developed transfer process, which does not cause any significant damage to the device layer. This technology will lead to a lightweight, shock‐resistant LCD panel suitable to mobile applications.
Priority-based cache allocation in throughput processors (2015)

GPUs employ massive multithreading and fast context switching to provide high throughput and hide memory latency. Multithreading can Increase contention for various system resources, however, that may result In suboptimal utilization of shared resources. Previous research has proposed variants of throttling thread-level parallelism to reduce cache contention and improve performance. Throttling approaches can, however, lead to under-utilizing thread contexts, on-chip interconnect, and off-chip memory bandwidth. This paper proposes to tightly couple the thread scheduling mechanism with the cache management algorithms such that GPU cache pollution is minimized while off-chip memory throughput is enhanced. We propose priority-based cache allocation (PCAL) that provides preferential cache capacity to a subset of high-priority threads while simultaneously allowing lower priority threads to execute without contending for the cache. By tuning thread-level parallelism while both optimizing caching efficiency as well as other shared resource usage, PCAL builds upon previous thread throttling approaches, improving overall performance by an average 17% with maximum 51%.
Altered skeletal expression of sclerostin and its link to radiographic progression in ankylosing spondylitis (2009)

Sclerostin expression is impaired in patients with AS, suggesting a specific alteration of osteocyte function in this disease. A low serum level of sclerostin in the setting of AS is linked to increased structural damage, emphasizing the role of sclerostin in the suppression of bone formation.
Polymerisation of a terpene-derived lactone: a bio-based alternative to ε-caprolactone (2016)

Topological control of p21WAF1/CIP1 expression in normal and neoplastic tissues. (1995)

The p53-regulated gene product p21WAF1/CIP1 is the prototype of a family of small proteins that negatively regulate the cell cycle. To learn more about p21WAF1/CIP1 regulation in vivo, monoclonal antibodies were developed for immunohistochemistry. These revealed that p21WAF1/CIP1 expression followed radiation-induced DNA damage in human skin in a pattern consistent with its regulation by p53. A detailed comparison of the human, rat, and mouse p21WAF1/CIP1 promoter sequences revealed that this induction was probably mediated by conserved p53-binding sites upstream of the transcription start site. In unirradiated tissues, p21WAF1/CIP1 expression was apparently independent of p53 and was observed in a variety of cell types. Moreover, there was a striking compartmentalization of p21WAF1/CIP1 expression throughout the gastrointestinal tract that correlated with proliferation rather than differentiation. As epithelial cells migrated up the crypts, the Ki67-expressing proliferating compartment near the crypt base ended abruptly, with the coincident appearance of a nonproliferating compartment expressing p21WAF1/CIP1. In colonic neoplasms, this distinct compartmentalization was largely abrogated. Cell cycle inhibitors are thus subject to precise topological control, and escape from this regulation may be a critical feature of neoplastic transformation.
A study on the motion vector prediction schemes for AVS (2005)

The motion vector prediction (MVP) is an important part of video coding. There have been numerous workings on the topic done by researchers before. In this paper, a continue study on MVP of video coding based on the workings of predecessors is made. The video sequences with various motion characteristics are further investigated. The characteristics of motion vectors of objects in video scenes are discussed briefly. Then, summarizing these characteristics, two MVP schemes for a new coding standard, Audio and Video Standard (AVS), are proposed. In these schemes, current block's MV can be predicted based on statistical correlation of MVs of spatial contiguous neighbor blocks. A correlation criterion is employed to measure how correlated between two MVs. With the correlation criterion, the correlated MVs of neighbor blocks are determined. Then, the predicted MV of current block can be obtained with some simple algebraic operations on determined MVs. The two proposed schemes, as the alternative ones of median predictor, are suitable for different video sequences with different motion characteristics, respectively. The experimental results show that the bit rate savings are achieved with these schemes in most of typical video sequences, compared with the median predictor implemented in AVS.
