Multi object tracking using multi threaded parallel approach

In this Paper, we proposed a method for tracking multi object using multithreading concept in a video. This method is based on continuously adaptive mean shift algorithm using color model which is designed to track multi object using multithreading concept by comparing it's mean in the successive frame of the video. It is observed that an object can be tracked in the next frame, when the mean shift vector converges. Simulation result shows that the proposed method is capable of detecting multi moving object quickly.
Exclusión y falta de integración social: Jornaleros veracruzanos asentados en Tamaulipas

En México los jornaleros constituyen el grupo social más marginal de la sociedad rural: sus ingresos son inferiores a los de cualquier otro grupo social, y el carácter estacional de la actividad que realizan implica que se vean obligados a emigrar en busca del escaso empleo disponible. En zona centro de Tamaulipas, compuesta por los municipios de Güémez, Hidalgo, Padilla, Victoria y Llera, la demanda de mano de obra en el sector citrícola se ha incrementado de modo notable durante las últimas décadas debido a la expansión del sector; de modo que esta actividad se ha tornado dependiente del empleo de trabajadores migratorios. La diferente estacionalidad de la pizca de la naranja en Veracruz y Tamaulipas, genera un circuito migratorio que parte de Veracruz en el mes de marzo, cuando comienza a escasear el trabajo allí, y se dirige hacia Tamaulipas, donde la temporada de la naranja comienza en la primavera. La mayor parte de los más de 5 mil jornaleros migratorios que llegan todos los años a Tamaulipas regresan a sus lugares de origen; pero cada vez es mayor el número de jornaleros que se han asentado de modo permanente en esta zona, lo cual genera profundos problemas de convivencia con la población local.
Information-Theoretically Optimal Compressed Sensing via Spatial Coupling and Approximate Message Passing

We study the compressed sensing reconstruction problem for a broad class of random, band-diagonal sensing matrices. This construction is inspired by the idea of spatial coupling in coding theory. As demonstrated heuristically and numerically by Krzakala [30], message passing algorithms can effectively solve the reconstruction problem for spatially coupled measurements with undersampling rates close to the fraction of nonzero coordinates. We use an approximate message passing (AMP) algorithm and analyze it through the state evolution method. We give a rigorous proof that this approach is successful as soon as the undersampling rate δ exceeds the (upper) Rényi information dimension of the signal, d̅(pX). More precisely, for a sequence of signals of diverging dimension n whose empirical distribution converges to pX, reconstruction is with high probability successful from d̅(pX) n+o(n) measurements taken according to a band diagonal matrix. For sparse signals, i.e., sequences of dimension n and k(n) nonzero entries, this implies reconstruction from k(n)+o(n) measurements. For “discrete” signals, i.e., signals whose coordinates take a fixed finite set of values, this implies reconstruction from o(n) measurements. The result is robust with respect to noise, does not apply uniquely to random signals, but requires the knowledge of the empirical distribution of the signal pX.
Torque Feedforward Control Technique for Permanent Magnet Synchronous Motors

This paper proposes a torque control method for Interior Permanent Magnet (IPM) motors operating in a wide speed range requiring high torque/power accuracy and fast dynamic response. Using the fact that the motor parameters are nonlinear and vary significantly with direct and quadrature current operating points, a new optimal operating plane is generated. This operating plane combines the PTPA (Peak Torque per Ampere) curve, current limit circle and MTPV (Maximum Torque per Volt) curve, voltage limitations and torque calculation under the nonlinear parameter variations. As a result, new feedforward tables are generated which make full use of measured motor parameters. The new torque and flux regulators built around the feedforward tables provide fast dynamic response and accurate steady state torque/power production. The proposed controller was implemented and successfully tested on a 105 kW IPM motor electric drive used in a fuel cell vehicle program.
Learning Bayesian Networks from Incomplete Data with Stochastic Search Algorithms

This paper describes stochastic search approaches, including a new stochastic algorithm and an adaptive mutation operator, for learning Bayesian networks from incomplete data. This problem is characterized by a huge solution space with a highly multimodal landscape. State-of-the-art approaches all involve using deterministic approaches such as the elrpectation-maximization algorithm. These approaches are guaranteed to find local maxima, but do not explore the landscape for other modes. Our approach evolves structure and the missing data. We compare our stochastic algorithms and show they all produce accurate results.
The random oracle methodology, revisited

We take a critical look at the relationship between the security of cryptographic schemes in the Random Oracle Model, and the security of the schemes that result from implementing the random oracle by so called "cryptographic hash functions". The main result of this article is a negative one: There exist signature and encryption schemes that are secure in the Random Oracle Model, but for which any implementation of the random oracle results in insecure schemes. In the process of devising the above schemes, we consider possible definitions for the notion of a "good implementation" of a random oracle, pointing out limitations and challenges.
Análisis de los modelos de uso público en la red de parques nacionales

Dentro del conjunto de los Espacios Naturales Protegidos (ENP) nos encontramos con la figura de Parque Nacional, la cual se aplica en aquellos espacios naturales de alto valor ecológico y cultural cuya conservación se considera de interés general para la nación. Desde su origen, y principalmente en las últimas décadas, el deseo de conservación materializado en la declaración de estos espacios tiene que compatibilizarse con la demanda recreativa de los mismos. Actualmente, existen catorce Parques Nacionales declarados por Ley, con problemas de gestión del uso público (UP) particulares, aunque muchos de ellos afines a otros ENP. El proyecto aquí presentado tiene como principal objetivo realizar un análisis de los modelos de UP que se siguen en cada una de las unidades de la Red declaradas a fecha de 2005, extrayendo recomendaciones para su mejora. Este objetivo principal se aborda desde varios ámbitos que se complementan y que permiten obtener una visión de conjunto. En primer lugar, a partir de una valiosa recopilación de información, se ha detectado la existencia de varios modelos de gestión del UP. A partir de la definición de criterios de calidad para la elaboración de un instrumento de evaluación de la gestión del UP se ha podido obtener una visión amplia del nivel de desarrollo de éste área, siendo calificado como de “notable” para el conjunto de la Red. Se han detectado ejemplos de buenas prácticas y establecido prioridades de mejora para cada parque y programa analizado. Utilizando la misma metodología cuantitativa, esta vez complementada con preguntas abiertas se ha analizado la calidad de los centros de visitantes. El conjunto de los mismos muestra una calidad alta en cuanto a sus instalaciones y funcionamiento, pero menor valor en cuanto a la funcionalidad de los mismos. Al igual que en el caso anterior se han detectado ejemplos de buenas prácticas, y establecido prioridades de mejora para cada centro analizado.
Chromosomal-Level Assembly of the Asian Seabass Genome Using Long Sequence Reads and Multi-layered Scaffolding

We report here the ~670 Mb genome assembly of the Asian seabass (Lates calcarifer), a tropical marine teleost. We used long-read sequencing augmented by transcriptomics, optical and genetic mapping along with shared synteny from closely related fish species to derive a chromosome-level assembly with a contig N50 size over 1 Mb and scaffold N50 size over 25 Mb that span ~90% of the genome. The population structure of L. calcarifer species complex was analyzed by re-sequencing 61 individuals representing various regions across the species’ native range. SNP analyses identified high levels of genetic diversity and confirmed earlier indications of a population stratification comprising three clades with signs of admixture apparent in the South-East Asian population. The quality of the Asian seabass genome assembly far exceeds that of any other fish species, and will serve as a new standard for fish genomics.
Inhaled Nitric Oxide Improves Gas Exchange and Lowers Pulmonary Vascular Resistance in Severe Experimental Hyaline Membrane Disease

ABSTRACT: To determine the effects of inhaled nitric oxide (NO) on pulmonary hemodynamics and gas exchange in experimental hyaline membrane disease (HMD), we studied 16 premature lambs (0.78 term) in two separate protocols. All animals were treated with exogenous surfactant before mechanical ventilation. In protocol 1, we measured the acute response to brief treatment with inhaled NO (20 ppm, 20 min) after 2 h of mechanical ventilation with fraction of inspired oxygen of 1.00 (n = 5). After 2 h, brief NO treatment lowered pulmonary vascular resistance from 0.26 ±0.05 to 0.16 ±0.03 mm Hg- (mL/min)−1 (p < 0.01) and improved gas exchange (arterial Po2, 44 ± 9 mm Hg baseline to 168 ± 45 mm Hg NO, p < 0.01; arterial Pco2 45 ± 5 mm Hg baseline to 35 ± 4 mm Hg NO, p < 0.05). In protocol 2, to determine whether early and continuous treatment with inhaled NO could sustain improvement in gas exchange and pulmonary hemodynamics in severe HMD, we compared the physiologic effects of ventilation with high inspired oxygen concentrations for 3 h with NO (20 ppm, n = 6) and without NO (controls, n = 5). After 3 h, the NO treatment group had sustained reduction in pulmonary vascular resistance (0.10 ± 0.01 mm Hg (mL/ min)−1 NO versus 0.25 ± 0.04 mm Hg (mL/min)−1 control, p < 0.05), increased left pulmonary artery blood flow (204 ± 24 mL/min NO versus 109 ± 15 mL/min control, p < 0.05), and increased arterial Po2 (114 ± 27 mm Hg NO versus 36 ± 11 mm Hg control, p < 0.05). We conclude that inhaled NO causes marked and sustained improvement in pulmonary hemodynamics and gas exchange in severe experimental HMD. We speculate that pulmonary vasoconstriction and ventilation/perfusion abnormalities contribute to the pathophysiology of severe respiratory failure in preterm newborns, and early treatment with inhaled NO may be effective in clinical management of selected premature patients with HMD.
Automatic image retargeting

We present a non-photorealistic algorithm for retargeting large images to small size displays, particularly on mobile devices. This method adapts large images so that important objects in the image are still recognizable when displayed at a lower target resolution. Existing image manipulation techniques such as cropping works well for images containing a single important object, and down-sampling works well for images containing low frequency information. However, when these techniques are automatically applied to images with multiple objects, the image quality degrades and important information may be lost. Our algorithm addresses the case of multiple important objects in an image. The retargeting algorithm segments an image into regions, identifies important regions, removes them, fills the resulting gaps, resizes the remaining image, and re-inserts the important regions. Our approach lies in constructing a topologically constrained epitome of an image based on a visual attention model that is both comprehensible and size varying, making the method suitable for display-critical applications.

An experimental analysis of a 2×2 MIMO transmitter using two-tones and WCDMA signal is presented.
The effects of processing on radiation damage in SiO2

This paper reviews the general interaction of radiation with thermally grown SiO2, both phenomenologically and atomistically. Radiation induced trapped charge, the creation of fast surface states and the all-important neutral electron traps are individually discussed. The types of radiation and their concomitant damage produced by the typical processes of ion implantation, reactive ion etching and E-Beam lithography are outlined. The effect of these processes on the oxidized silicon system is treated and process modification to minimize radiation damage is discussed.
Continuous Speech Recognition from Phonetic Transcription

Previous research by the authors has been directed toward phonetic transcription of fluent speech. We have applied our techniques to speech recognition on the DARPA Resource Management Task. In order to perform speech recognition, however, the phonetic transcription must be interpreted as a sequence of words. A central component of this process is lexical access for which a novel method is proposed.
Fast thermal profiling of power semiconductor devices using Fourier techniques

Accurate prediction of temperature variation of power semiconductor devices in power electronic circuits is important to obtain optimum designs and estimate reliability levels. Temperature estimation of power electronic devices has generally been performed using transient thermal equivalent circuits. In the presence of varying load cycles, it has been typical to resort to a time domain electrical simulation tool such as P-Spice/sup TM/ or SABER/sup TM/ to obtain a time series of the temperature profiles. However, for complex and periodic load cycles, time series simulation is time consuming. In this paper, a fast fourier analysis based approach is presented for obtaining temperature profiles for power semiconductors. The model can be implemented readily into a spreadsheet or simple mathematical algebraic calculation software. The technique can be used for predicting lifetime and reliability level of power circuits easily. Details of the analytical approach and illustrative examples are presented in the paper.

Digital Preservation of Interactive Multimedia Performances

A developing apparatus is provided in which a developer material in a development tank is made to circulate through a developer material storage vessel detachably mounted on the development tank, thereby prolonging the service life of the developer material. In the developing apparatus of the present invention, a predetermined developer material composed of a toner and a carrier stored in a development tank 31 is stirred by a stirring roller 33, and supplied to a latent image formed on a photoreceptor 11 by means of a development roller 32 in the development tank to visualize the latent image. The concentration of the toner consumed in the development tank is detected by a toner concentration sensor 34 so that toner is supplied from a toner storage tank 41 to the development tank so as to maintain the concentration of the toner at a constant level. In this case, a developer material conveyor shaft 37a discharges the developer material from the development tank to a developer material storage vessel 50, and a developer material conveyor shaft 37b makes the developers material received from the developer material storage tank into the development tank thereby to control the amount of developer material and the concentration of the toner in the development tank to be constant. The developer material storage vessel is replaced with a new one at proper times so as to gradually refresh the developer material therein.
Memory consistency and event ordering in scalable shared-memory multiprocessors

A new model of memory consistency, called release consistency, that allows for more buffering and pipelining than previously proposed models is introduced. A framework for classifying shared accesses and reasoning about event ordering is developed. The release consistency model is shown to be equivalent to the sequential consistency model for parallel programs with sufficient synchronization. Possible performance gains from the less strict constraints of the release consistency model are explored. Finally, practical implementation issues are discussed, with the discussion concentrating on issues relevant to scalable architectures. <<ETX>>
SPEECH IS CHARACTERIZED BY ROBUSTNESS, NEUTRALITY AND EVOLVABILITY

Language is incredibly robust. Humans are able to talk to one another despite noise, and despite variation within and between speakers. In this synthetic paper, I will draw analogies between robustness in biology and robustness in language. Focusing on speech as both a phonetic and a phonological entity, I will show that some of the same ways in which living systems achieve robustness (Kitano, 2004; Wagner, 2005) are also ways in which speech achieves robustness. Two principles are especially important:
The Efficacy of 1% Chlorhexidine Gel on the Reduction of Dry Socket Occurence Following Surgical Third Molar Extraction— Pilot Study

Aim & Objectives: The aim of this prospective pilot-study was to assess the efficacy of intra alveolar application of 1% chlorhexidine gel (CHX) on the reduction of dry socket (DS) occurrence following surgical extraction of mandibular third molars. Materials and Methods: A randomized split-mouth-design study included twenty-five patients with bilaterally impacted lower third molars (partial or full bone) requiring full thickness mucoperiastal flap reflection for extraction. Following surgical extraction of third lower molar, 2 ml of gel containing 1% chlorhexidine digluconate (Chlorhexamed? Gel 1%) were placed in the experimental side, and saline solution was used for irrigation in the control side of extraction sockets, both followed by suturing of extraction site. The surgeries and follow up examinations were performed by the same surgeon. The follow up visits were performed at 48 hours and on day seven, post surgery where presence or absence of dry socket using the Blum criteria for diagnosis was evaluated and pain intensity by Visual Analogue Scale (VAS) 0 - 100 was observed. Results: In this pilot study, dry socket was present in 4.0 and 28.0% of cases in the experimental and control groups, respectively (P = 0.048). Fisher’s test revealed a statistically significant reduction of dry socket occurrence following the use of 1% CHX gel versus saline solution. Conclusion: The application of CHX gel 1% may significantly reduce the incidence of DS following third molar extraction. Prophylactic use of CHX gel 1% may be suggested in all patients, especially in the patients at risk of development of DS.
Temperature dependent dielectric spectroscopy in frequency domain of high-voltage transformer oils compared to physicochemical results

The temperature dependent dielectric spectroscopy in frequency domain is compared to physicochemical and electrical tests that are periodically applied on highly insulating transformer oils. Complex permittivity and tandelta data are obtained as a function of frequency and operation temperatures, to demonstrate the polarization phenomena and the induced loss intensification by the thermally stimulated currents. The acquired dielectric data of oil samples collected from 201 operating high voltage (HV) power transformers, were correlated to their corresponding physicochemical ones in order to demonstrate the future potential employment of the proposed measuring technique in the field of high voltage engineering, towards reliability monitoring of oil filled electrical equipment (OFEE)
Book Review: The Social Media Age by Zoetanya Sujon

This book review and commentary provides an institutional perspective of the book, The Social Media Age. It explores the broader impact of social media on our lives and it also outlines the opportunities associated with social media as well. Scholarly work, as well as trade and popular press, has examined the ills of social media. However, often neglected in these views is a macro, institutional perspective acknowledging the complexities and interconnections between various actors and entities. This commentary brings to fore the importance of examining social media from an institutional perspective within the context of The Social Media Age.
A Phase-Domain Synchronous Machine Model With Constant Equivalent Conductance Matrix for EMTP-Type Solution

Interfacing machine models in either nodal analysis-based (EMTP-like) or state variable-based transient simulation programs play an important role in numerical accuracy and computational performance of the overall simulation. As an advantageous alternative to the traditional qd models, a number of advanced phase-domain (PD) and voltage-behind-reactance machine models have been recently introduced. However, the rotor-position-dependent conductance matrix in the machine-network interface complicates the use of such models in EMTP. This paper focuses on achieving constant and efficient interfacing circuit for the PD synchronous machine model. It is shown that the machine conductance matrix can be formulated into a constant submatrix plus a time-variant submatrix. Eliminating numerical saliency from the second term results in a constant conductance matrix of the proposed PD model, which is a very desirable property for the EMTP solution since the refactorization of the network conductance matrix at every time step is avoided. Case studies demonstrate that the proposed PD model represents a significant improvement over other established models used in EMTP while preserving the accuracy of the original/classical PD model.
