Anomaly Detection and Degradation Prediction of MOSFET (2015)

The MOSFET is an important power electronic transistor widely used in electrical systems. Its reliability has an effect on the performance of systems. In this paper, the failure models and mechanisms of MOSFETs are briefly analyzed. The on-resistance<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mrow><mml:mfenced separators="|"><mml:mrow><mml:msub><mml:mrow><mml:mi>R</mml:mi></mml:mrow><mml:mrow><mml:mtext>on</mml:mtext></mml:mrow></mml:msub></mml:mrow></mml:mfenced></mml:mrow></mml:math>is the key failure precursor parameter representing the degree of degradation. Based on the experimental data, a nonlinear dual-exponential degradation model for MOSFETs is obtained. Then, we present an approach for MOSFET degradation state prediction using a strong tract filter based on the obtained degradation model. Lastly, the proposed algorithm is shown to perform effectively on experimental data. Thus, it can provide early warning and enhance the reliability of electrical systems.
Metamaterial with Simultaneously Negative Bulk Modulus and Mass Density (2007)

We report a metamaterial which simultaneously possesses a negative bulk modulus and mass density. This metamaterial is a zinc blende structure consisting of one fcc array of bubble-contained-water spheres (BWSs) and another relatively shifted fcc array of rubber-coated-gold spheres (RGSs) in epoxy matrix. The negative bulk modulus and mass density are simultaneously derived from the coexistent monopolar resonances from the embedded BWSs and dipolar resonances from the embedded RGSs. The Poisson ratio of the metamaterial also turns negative near the resonance frequency.
Increasing Passive RFID-Based Smart Shopping Cart Performance using Decision Tree (2019)

This paper proposes the smart shopping cart based on passive RFID. While on peak season market, queues are often found at clothing store. This happens because the service time between consumers takes a long time; the cashier must scan all items one by one, and make the transaction process at the cashier slow. In proposed system, each item be equipped with an RFID tag, and the shopping cart be equipped with an RFID reader, so the items that are inserted into the shopping cart will be scanned and calculated in the system. This system makes the service time shorter and minimize the number of queues at the cashier. To support the performance of smart shopping cart, a decision tree algorithm is implemented for classifying consumer shopping lists and determine discounts. The author tests and analyzes the performance of the decision tree ID3 algorithm in the smart shopping cart. The test results show that decision tree algorithms can determine discounts with a 90% accuracy rate and 100% precision rate.
Calibrated Fabry-Perot etalon as an absolute frequency reference for OFDM communications (1992)

The frequency locking of a large number of lasers in OFDM applications requires an equally large number of stable references at predictable frequencies. The authors present a technique to lock a Fabry-Perot etalon on an atomic reference to provide multiple and evenly spaced absolute frequency references. Absolute etalon spacing is calibrated by matching two atomic references with two corresponding etalon modes. To maintain long-term stability in channel spacing, the etalon is locked to an atomic resonance using an electrical feedback loop to control mirror separation. This technique can be used for close spacing or coherent applications where channel separation and reproducibility is critical between transmitter and receiver.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Purification of Nucleic Acids by Hybridization to Affinity Tagged PNA Probes (1999)

The use of affinity tagged PNA capture probes offers an efficient means for the purification of nucleic acids by hybridization. Two different approaches are described. A sequence specific method and a generic method. The sequence specific method requires sequence information on the target and synthesis of a dedicated PNA. It can be used to selectively purify the nucleic acid containing the target from non-related nucleic acids and other cellular components. The generic method uses a "universal" triplex forming PNA and requires no sequence information on the target. It can be used in the bulk purification of large nucleic acids.

Electronic Scheme for Computing Inverse-Cosine and its Application to a GMR Based Angle Sensor (2012)

This paper presents a new, simple but effective, electronic method to obtain inverse-cosine of an electrical variable. The proposed method is very useful for linearization of sensors whose output is a cosine or sine function of the physical quantity being sensed. The inverse-cosine of the variable is obtained by comparing it with a reference sinusoidal wave. The proposed method is easy to implement using electronic components. Using the new technique, a giant magneto-resistance-based angle sensor that provides an output linearly proportional to the angle being sensed has been developed, and the details are reported in this paper. A prototype of the angle sensor has been built, and the practicality of the new method has been tested successfully. The developed sensor provides a linear output for a range of 0° to 180°. The worst case error was found to be less than 0.35° for a range of 10°-170°.
Corrosion Prediction and Materials Selection for Oil and Gas Producing Environments (2005)

Abstract A computer model is described which predicts corrosion rates of carbon steel flowlines and tubing in the presence of carbon dioxide. The model can be applied also for processing facility piping and equipment. The influences of dissolved corrosion products, hydrogen sulfide, crude oil type, acetic acid and flow regime on the corrosion rate are predicted. Inhibition scenarios can be compared and, for highly corrosive environments, the model incorporates the evaluation of a number of Corrosion Resistant Alloys and incorporates a life-cycle cost evaluation.
Pd<sup>0</sup>‐Catalyzed Coupling Cyclization Reaction of Aryl or 1Alkenyl Halides with 1,2‐Allenyl Ketones: Scope and Mechanism. An Efficient Assembly of 2,3,4‐, 2,3,5‐Tri‐ and 2,3,4,5‐Tetrasubstituted Furans (2003)

Described herein is the Pd(0)-catalyzed coupling cyclization reaction of 1,2-allenyl ketones with organic halides leading efficiently and conveniently to not only 2,3,4- and 2,3,5-trisubstituted furans but also 2,3,4,5-tetrasubstituted furans. Furthermore, this method showed high substituent-loading capability and tolerance of various substituents. The reactions of 1,2-allenyl ketones 1 e, 1 p, 1 q, and deuterated [D]1 c were performed for a mechanistic study, which demonstrated that instead of an enolization pathway, the reaction may proceed via the intermediacy of dienolate palladium and intramolecular nucleophilic attack on the pi-allyl palladium intermediate by the carbonyl oxygen.
IV. Theories of Law and Government (2010)

Abstract This chapter on theories of law and government begins with a discussion of the thought of Jeremy Bentham. It then discusses John Austin's reformulation of the province of jurisprudence, intuitionists and utilitarians, theories of evolution, individualism versus socialism, and late 19th-century jurisprudence.
The combination of epigallocatechin gallate and curcumin suppresses ERα‐breast cancer cell growth <i>in vitro</i> and <i>in vivo</i> (2007)

Both epigallocatechin gallate (EGCG) and curcumin have shown efficacy in various in vivo and in vitro models of cancer. This study was designed to determine the efficacy of these naturally derived polyphenolic compounds in vitro and in vivo, when given in combination. Studies in MDA-MB-231 cells demonstrated that EGCG + curcumin was synergistically cytotoxic and that this correlated with G(2)/M-phase cell cycle arrest. After 12 hr, EGCG (25 microM) + curcumin (3 microM) increased the proportion of cells in G(2)/M-phase to 263 +/- 16% of control and this correlated with a 50 +/- 4% decrease in cell number compared to control. To determine if this in vitro result would translate in vivo, athymic nude female mice were implanted with MDA-MB-231 cells and treated with curcumin (200 mg/kg/day, po), EGCG (25 mg/kg/day, ip), EGCG + curcumin, or vehicle control (5 ml/kg/day, po) for 10 weeks. Tumor volume in the EGCG + curcumin treated mice decreased 49% compared to vehicle control mice (p < 0.05), which correlated with a 78 +/- 6% decrease in levels of VEGFR-1 protein expression in the tumors. Curcumin treatment significantly decreased tumor protein levels of EGFR and Akt, however the expression of these proteins was not further decreased following combination treatment. Therefore, these results demonstrate that the combination of EGCG and curcumin is efficacious in both in vitro and in vivo models of ER alpha-breast cancer and that regulation of VEGFR-1 may play a key role in this effect.
Development of GEM Detectors at Hampton University (2019)

Two GEM telescopes, each consisting of three 10x10 cm2 triple-GEM chambers were built, tested and operated by the Hampton University group. The GEMs are read out with APV25 frontend chips and FPGA based digitizing electronics developed by INFN Rome. The telescopes were used for the luminosity monitoring system at the OLYMPUS experiment at DESY in Hamburg, Germany, with positron and electron beams at 2 GeV. The GEM elements have been recycled to serve in another two applications: Three GEM elements are used to track beam particles in the MUSE experiment at Paul Scherrer Institute in Switzerland. A set of four elements has been configured as a prototype tracker for phase 1a of the DarkLight experiment at the Low-Energy Recirculator Facility (LERF) Jefferson Lab in Newport News, USA, in a first test run in summer 2016. The Hampton group is responsible for beam particle tracking in the MUSE@PSI and for the DarkLight phase-I lepton tracker in preparation. Further efforts are ongoing to optimize the data acquisition speed for GEM operations in MUSE and DarkLight. An overview of the group’s GEM detector related activities will be given. This work is presently supported by NSF PHY-1436680 and HRD-1649909.
Evaluation of a system to identify relevant patient information and its impact on clinical information retrieval. (1999)

Concept-oriented views of electronic medical records are desirable, yet difficult to create. We have developed a system that creates concept-oriented views by identifying relevant patient information, however, previous such systems have received little evaluation. We present here an evaluation of our system's ability to identify relevant patient data and generate concept-oriented views, along with the clinical impact of the generated views. The evaluation was carried out in three parts: First, using physicians and medical literature as gold standards, the system's sensitivity and specificity in identifying relevant information were measured. In some areas, the system demonstrated sensitivity comparable to that of physicians. Second, concept-oriented views were compared with original records and shown to contain significantly less non-specific information. Third, physician volunteers, when answering questions about patient cases using the concept-oriented views and traditional source-oriented views generated by the system, showed a significantly greater accuracy in information retrieval using concept-oriented views.
Performance of seed germination and growth of Vicia faba L. in fly ash amended soil. (2003)

The performance of Vicia faba L. in soil amended by different concentrations of fly ash has been studied. The parameters considered are seed germination, growth behaviour and nodulation frequency of the plant. Results revealed that while fly-ash amendment to the soil improved the growth performance at initial stages with application of lower concentrations, it was inhibitory at higher exposure concentrations. Although there was no difference in survival rates, but the seedling growth was reduced in comparison to control plants. Fly ash delayed the nodulation as lesser number of nodules was recorded at higher amendments. Results suggested feasibility of growing V. faba in fly ash contaminated area.

The system bit error rate performance has been observed for 72 h without degradation.
Evaluating Automatic Term Extraction Methods on Individual Documents (2019)

Automatic Term Extraction (ATE) extracts terminology from domain-specific corpora.ATE is used in many NLP tasks, including Computer Assisted Translation, where it is typically applied to individual documents rather than the entire corpus.While corpus-level ATE has been extensively evaluated, it is not obvious how the results transfer to documentlevel ATE.To fill this gap, we evaluate 16 state-of-the-art ATE methods on full-length documents from three different domains, on both corpus and document levels.Unlike existing studies, our evaluation is more realistic as we take into account all gold terms.We show that no single method is best in corpuslevel ATE, but C-Value and KeyConceptRelatendess surpass others in document-level ATE.
Counterfeit Currency Detection Technique Using Image Processing, Polarization Principle and Holographic Technique (2013)

The growing menace of fake or counterfeit currency is one of the biggest threat to any nations economy across the globe and to ameliorate this threat is a far cry, so through this paper titled DIGITIZED CURRENCY we provide an innovative method to identify the counterfeit currency, (i.e) it encompasses polarization concept, Image processing technique, and Holographic Detection methods to detect counterfeit currency based on the physical properties of the currency rather than the existing methodology that relay on its chemical property. This is achieved by providing mathematical model, experimental verification and Lab view based simulation and also through automation to enhance reliability and accuracy in a cheaper, efficient and dynamic way in detecting the counterfeit currency.
The role of G-protein-coupled receptors in mediating the effect of fatty acids on inflammation and insulin sensitivity (2011)

These studies provide a new understanding of the general biology of gastric motility and also shed valuable insight into some potentially beneficial therapeutic targets. Furthermore, highly selective agonists or antagonists for the free fatty acid receptors have been developed and look promising for treating various metabolic diseases.
Design of a Small UAV Combined Between Flying-Wing and Quadrotor with XFRL5 (2016)

The design process of a product is a multi-step process of selection and assessment criteria to create a final product which meets all the needs of the practice. A small UAV combined between flying-wing and quadrotor is a very complex product, so the design process of this small UAV requires a thorough and circumspect review. The problem is how to optimize the design and to carry out the testing of the feasibility of design requirements with the lowest cost and time savings. For that reason, many tools of Multi-Fidelity Analysis for UAV such as XFLR5, XFoil… have been used to give considerable support for this design process. This research focusses mainly on the analysis/design of the configuration of a small UAV flying wing based on the performance at its cruise speed.

Atrial fibrillation is associated with periventricular white matter lesions, but not with subcortical white matter lesions.
The simultest approach for testing mutagens in the <i>Salmonella</i> Microtitre fluctuation assay (1990)

The concept of combining several histidine-dependent Salmonella strains in a single test, the SIMULTEST, has been applied to the microtitre fluctuation test. The activity of five mutagens was determined in strains TA97, TA98, TA100, and TA102 individually as well as in a SIMULTEST mixture. All five compounds were mutagenic in the SIMULTEST, demonstrating the utility of this time and labour-saving approach of combining strains for testing with this method. The microtitre fluctuation SIMULTEST results were quantitatively comparable to those of the SIMULTEST Salmonella/microsome plate test. The microtitre fluctuation test compared with the plate incorporation assay generally showed more favourable "sensitivity" and "quantity" indices in that four of the five chemicals tested in the fluctuation test were mutagenic at lower doses than in the plate test.
Confiabilidade e validade das medidas da cifose torácica através do método flexicurva (2007)

CONTEXTUALIZAÇÃO: A hipercifose torácica é uma das alterações posturais mais comuns, sendo definida como um aumento da curvatura torácica no plano sagital da coluna vertebral. Uma cifose normal varia de 20 a 50º quando avaliada pelo método radiográfico de Cobb. O método radiográfico é o mais popular para mensuração da cifose, mas em função de ser um método caro e que expõe os sujeitos a radiação, não é o método mais adequado para acompanhamento periódico do paciente. Exames clínicos de rotina, como a avaliação fisioterapêutica da cifose torácica, devem ser válidos, confiáveis, sensíveis, práticos e baratos. OBJETIVOS: Verificar a validade concorrente e as confiabilidades intra e interavaliador das medidas de cifose torácica utilizando o Método Flexicurva. MÉTODOS: Estudo transversal em que a cifose torácica de 56 pessoas foi avaliada em radiografias sagitais da coluna torácica pelo método de Cobb e pelo Método Flexicurva por dois avaliadores. RESULTADOS: O coeficiente de correlação intraclasse (ICC) entre as medidas pelo Cobb e pelo método Flexicurva foi de 0,906. A sensibilidade foi de 85%, a especificidade de 97% para diagnosticar a hipercifose torácica. CONCLUSÃO: O Método Flexicurva demonstra ser um parâmetro clínico quantitativo excelente para mensuração da curvatura da cifose torácica.

Sequential structure and parameter-adaptive pattern recognition--I: Supervised learning (1970)

Bayes optimal sequential structure and parameter-adaptive pattern-recognition systems for continuous data are derived. Both off-line (or prior to actual operation) and on-line (while in operation) supervised learning is considered. The concept of structure adaptation is introduced and both structure as well as parameter-adaptive optimal pattern-recognition systems are obtained. Specifically, for the class of supervised-learning pattern-recognition problems with Gaussian process models and linear dynamics, the adaptive pattern-recognition systems are shown to be decomposable ("partition theorem") into a linear nonadaptive part consisting of recursive matched Kalman filters, a nonlinear part--a set of probability computers--that incorporates the adaptive nature of the system, and finally a part of the correlator-estimator (Kailath) form.

Translocation of active mitochondria during pig oocyte maturation, fertilization and early embryo development in vitro (2001)

The distribution of active mitochondria during pig oocyte maturation, fertilization and early embryo development in vitro was revealed by using MitoTracker Green staining and confocal laser scanning microscopy. The regulation of mitochondrial translocation by microfilaments and microtubules was also studied. In oocytes collected from small follicles, strong staining of active mitochondria was observed in the cell cortex. Accumulation of active mitochondria in the peripheral cytoplasm and around the germinal vesicles was characteristic of fully grown oocytes collected from large follicles. Mitochondria accumulated in the perinuclear area during meiotic progression from germinal vesicle breakdown (GVBD) to anaphase I. Larger mitochondrial foci were formed and moved to the inner cytoplasm in mature oocytes. Compared with the oocytes matured in vivo, in which large mitochondrial foci were distributed throughout the cytoplasm, mitochondria were not observed in the central cytoplasm in most of the oocytes matured in vitro. Strong staining of mitochondria was observed in the first polar bodies in metaphase II oocytes. In fertilized eggs, active mitochondria aggregated in the pronuclear region. Perinuclear clustering and a cortical ring were the most marked features of early cleavage. Active mitochondria were distributed in both inner cell mass cells and trophectoderm cells of the blastocysts. Disassembly of microtubules with nocodazole inhibited both mitochondrial aggregations to the germinal vesicle area and their inward movement to the inner cytoplasm during oocyte maturation, as well as the translocation of mitochondria to the peri-pronuclear region during fertilization, whereas disruption of microfilaments by cytochalasin B had no effects. These data indicate that: (i) oocyte maturation, fertilization and early embryo development in pigs are associated with changes in active mitochondrial distribution; (ii) mitochondrial translocation is mediated by microtubules, but not by microfilaments; and (iii) in vitro maturation conditions may cause incomplete movement of mitochondria to the inner cytoplasm and thus affect cytoplasmic maturation.
A Roving User Modeling Framework for Location Tracking Applications (2006)

With the advent of GPS systems, location tracking has become an essential component of fleet management systems. Reliable location estimation of the location of each member of the fleet is critical for optimum operation of organizations such as the police force, taxi-cab, and trucking companies. In this paper a framework for modeling drivers in such environments for location tracking purposes is proposed. The framework's goal is to increase the LTS's ability to accurately answer queries about the whereabouts of its fleet members in the past, present, and the future
