T Source Inverter Based Shunt Active Filter with LCL Passive Filter for the 415V 50 Hz Distribution systems

The inverter topology is being used as an active filter to reduce the harmonics in the power system. The traditional voltage source or current source inverters are having the disadvantages of limited output voltage range hence it may not be able to supply enough compensating currents during heavy switching surges, Vulnerable to EMI noise and the devices gets damaged in either open or short circuit conditions and the main switching device of VSI and CSI are not interchangeable. The active filters are the type of DC-AC system with wide range of voltage regulation and integration of energy storages is often required. This cannot be achieved with conventional inverters and hence the impedance source inverters have been suggested. The T source inverters are basically impedance source inverters which can be used as an active filter in the power system. The MATLAB simulation is done and the results are discussed in this paper for both the types. The proposed dampening system is fully characterized by LCL based passive filters and T source inverter based shunt active filter. The disturbances in the supply voltage and load current due to the non linear loads are observed in the simulation. The same is studied after connecting the designed hybrid shunt active filter in the distribution system. The simulation results obtained from the proposed method proves that it gives comparatively better THD value. Full Text: PDF DOI: http://dx.doi. org/10.11591/ijpeds.v6. i2.pp268-273

There is a huge difference between general multimedia teaching courseware, multimedia teaching courseware based on multimedia technology, is refers to the general teaching software, is based on certain teaching target performance that reflects a specific teaching content, the teaching strategy of multimedia applications, it is the use of computer multimedia technology to text, graphics, sound, animation, and other media together to form. In the future, we plan to conduct more case studies to prove the effectiveness of the approach.
An overview of technology, architecture and CAD tools for programmable logic devices

Before the advent of programmable logic devices (PLDs), most digital hardware designs included significant numbers of small-scale integrated (SSI) circuits that comprised basic logic gates and flip-flops. However, modem designs contain virtually none of these low-density parts, but instead are built from more complex devices that consist of an uncommitted array of logic gates and memory elements that can be configured by the user to implement different circuits. The term programmable logic device is not easy to define because the assortment of chips that fall within this broad category, namely any integrated circuit that is programmable by the end user and intended for implementing hardware, has grown very large over the past few years. In fact, even the relevant terminology has become nebulous because of rapid technology changes and the introduction of new innovative architectures. The purpose of this paper is to provide an overview of programmable logic devices in order to present the reader with a clear view of what is available on the market today. The fundamental technologies employed to manufacture PLDs are presented, after which for each of the three categories of chips, namely simple programmable logic devices (SPLDs), complex programmable logic devices (CPLDs), and field-programmable gate arrays (FPGAs), the paper describes the most significant architectural features, examples of applications, and the CAD tool design now typically used when implementing circuits. <<ETX>>
Would evolutionary computation help in designs of ANNs in forecasting foreign exchange rates?

This paper evaluates the relevance of evolutionary artificial neural nets to forecasting the tick-by-tick DEM/USD exchange rate. With an analysis based on modern econometric techniques, this time series is shown to be a complex nonlinear series, and is qualified to be a challenge for ANNs and EANNs. Based on the five criteria, including the Sharpe ratio and a risk-adjusted profit rate, we compare the performance of 8 ANNs, 8 EANNs and the random-walk model. By the Granger-Newbold test, it is found that all neural network models can statistically beat the RW model in all criteria at the 1% significance level. In addition, among the 16 NN models generated in different designs, the best model is the EANN with the largest search space.
Decision-Theoretic Evaluation of Therapy Plans

Abstract Medical decision-support systems that make recommendations for action require a mechanism for comparing the available alternatives. In developing a computer-based system to provide ventilator-setting recommendations, the decision-theoretic concept of a multiattribute value model was used to rank potential plans. The possible treatment plans represent a continuum of choice rather than several discrete options. Physician preferences are obtained by using an automated assessment tool that uses a physiologic model to simulate patient responses to therapy. The decision-theoretic approach described here is able to differentiate among continuous options, is efficient enough to be used in a real time setting, and makes explicit the criteria for selecting plans.
Artificial neural networks for boundary extraction

Artificial neural networks are designed to detect edges and extract boundaries. The system can accomplish the following tasks: 1) obtain enhanced boundaries; 2) recover missing edges; and 3) eliminate false edges caused by noise. The research comprises two phases, namely, boundary extraction by a BP net and boundary enhancement by a modified Hopfield neural network. The BP net is trained by 560 typical boundary patterns to enable the network to determine the boundary elements with 8 orientations and to provide the boundary measurement for further processing. A modified Hopfield net is proposed to enhance boundary measurement. Based on constraint satisfaction and the competitive mechanism, interconnection between neural cells are determined. A criteria is provided to find the final stable result which contains the enhanced boundary measurement. The neural network was simulated on a SUN Sparc station. Test images were degraded by random noise up to 30% of the original images. Comparing with the Gaussian edge detection and optimum edge detection, the results are very promising: boundaries were extracted, noise was eliminated, and boundary elements missed in other methods were detected.
A Novel DVS Algorithm for Real Time Embedded Operating Systems

Abstract Energy efficiency is an important property of mobile and pervasive computing devices. Dynamic voltage scaling (DVS) is an energy saving technique, which is achieved by reducing energy dissipation of the core by lowering the supply voltage and operating frequency. In this paper a novel DVS algorithm is presented, which achieves better energy savings with deadline guarantees using real-time scheduling and task splitting technique. The proposed DVS algorithm is compared with existing RT-DVS algorithms for real-time periodic task sets, analyzing their energy efficiency, and discussing the performance differences quantitatively. The simulation results show that the proposed algorithm closely approaches the theoretical lower bound on energy consumption and reduces the energy consumption by 10–15% over the existing DVS algorithm.
A public key cryptography-based security enhanced mail gateway with the mailing list function

When sending corporate secrets by electronic mail (e-mail), care must be taken to protect the security of the information against the various kinds of illicit manipulation that can occur on the Internet. We have developed a security enhanced mail gateway (SEMAIL) that ensures the privacy of e-mail messages without requiring users to install new software or learn complicated operating procedures. The SEMAIL system, in which an encryption program PGP (Pretty Good Privacy) is used, is available for both POP3-based Unix mails and PC-LAN-based ones.

Audition et démasquage binaural chez l'homme

Contexte : Le demasquage binaural est un processus indispensable pour la comprehension en environnement bruyant. Ce mecanisme ferait intervenir la comparaison d’indices temporels et frequentiels tout au long des voies nerveuses auditives. Cependant, il n’existe pas de reel consensus evoquant un traitement du demasquage a un niveau sous-cortical et/ou cortical. L’objet de cette etude est d’etudier ces indices temporels et frequentiels du demasquage par le biais d’une etude perceptive, puis d’une etude electroencephalographique (EEG). Materiels et methodes : Une population normoentendante a ete evaluee lors d’une etude perceptive visant a estimer l’importance du demasquage en fonction de 1) la largeur frequentielle du bruit controlateral (de 1 octave, 3 octaves ou a large bande), 2) la coherence temporelle des bruits bilateraux (correlation egale a 0 ou 1) et 3) la frequence des stimuli cibles (0,5, 1, 2 et 4 kHz). Puis, le demasquage a ete evalue en EEG par l’etude 1) des latences precoces (<10 ms, PEA-P), 2) des latences tardives (<50 ms, PEA-T) et 3) de l’onde de discordance (PEA-MMN). Pour ces trois etudes EEG, l’influence de la coherence temporelle des bruits bilateraux a ete exploree.Resultats : L’etude perceptive traduit un demasquage croissant lorsque la largeur frequentielle du bruit controlateral augmente. L’ajout du bruit controlateral non correle (correlation=0) se traduit par une amelioration de detection de 1,28 dB, quelle que soit la frequence des stimuli cibles (antimasquage), alors que l’ajout d’un bruit controlateral correle (correlation=1) evoque une amelioration de detection lorsque la frequence des stimuli cibles diminue (demasquage) : 0,97 dB a 4 kHz et 9,25 dB a 0,5 kHz. En PEA-P, les latences des ondes III et V se raccourcissent lorsqu’un bruit controlateral correle ou non correle est ajoute (≈0,1 ms). En PEA-T, les amplitudes des ondes P1, N1 et des complexes P1N1 et N1P2 augmentent lorsqu’un bruit controlateral correle ou non correle est ajoute. Enfin, l’amplitude de la MMN est plus consequente lorsque le bruit controlateral ajoute est correle (versus non correle). Conclusion : L’etude perceptive explicite l’importance des indices spectraux (antimasquage) et temporels (demasquage), pour ameliorer la perception d’un signal initialement masque. L’etude EEG suggere, quant a elle, un traitement sous-cortical influence uniquement par les indices spectraux (antimasquage) et un traitement plus cortical influence par les indices temporels (demasquage).
Refinement in Biomedical Communication: A Case Study

Despite a general declaration of support among researchers for peer review in biomedical publication, biomedical journals vary considerably in their practices of criticism. Some publications ask referees to examine all papers submitted; on other journals, the editors decide without the assistance of reviewers. At some journals, a single editor makes a decision after reading reviewers' comments; elsewhere, a panel of editors makes the evaluation. Some journals require no review at all when members of the society or organization that sponsors the journal submit a paper for publication. There is also variation in the intensity of the dialogue between authors and editorial censors. Some journals make an effort to provide feedback to authors of papers and sometimes encourage resubmission of papers after revision. Other journals do not offer this service and simply notify the author of acceptance or rejection-thumbs up or thumbs down. Therefore, papers interface with journals in one of three ways: (1) automatic acceptance for privileged authors; (2) acceptance or rejection without explanation or accountability; (3) an editorial dialogue. Only the third approach provides a formal mechanism for "refinement" of papers, defined as making changes in response to a journal's reactions to the submitted paper (although it is possible that authors refine rejected papers when they resubmit them to other journals). The many avenues to publication indicate a general lack of consensus concerning the need for criticism
Tailoring and conformance testing of software processes: the ProcePT approach

Activities to be performed and documents to be produced or modified are the basic elements of a software process. They are grouped according to aspects of development, quality assurance, configuration management or project management. Activities might be refined or generalized. Each resulting process can be tested separately or in context with all of the other processes, whether it is enactable and whether standard conformity is given. A protocol of the tailoring and conformance testing process is recorded in order to fulfill quality management requirements. As a consequence, model consistency as well as standard conformance (e.g. to ISO9000-3) can be shown. The tailoring and consistency and conformance testing of software processes are supported by the tool ProcePT implemented in Prolog. The entire process of tailoring and conformance testing is recorded and therefore conforms to duality management standard requirements.

Decentralized PID Controller Design for 3x3 Multivariable System using Heuristic Algorithms

Background/Objectives: The objective is to design decentralised PID Controller for 3x3 multivariable system using heuristic algorithms. Methods/Statistical analysis: It is very difficult to control Multivariable system is in the process industries due to the interaction between the process variables. It needs a decentrlised PID controller scheme for the effective control. Here, Ogunnaike and Ray distillation column is considered as an example for simulation. The PID controllers are tuned using using Firefly (FA) and Particle Swarm Optimization (PSO) algorithm for diagonal elements of the transfer function. Findings: From the Simulation it is observed that the performance of Firefly is better than Particle Swarm Optimization for the chosen process model in terms of Integral Square (ISE) and peak overshoot. Application/Improvements: This method of controller design can be used for other distillation column (Example: Wood-berry distillation column). Different optimization algorithm can be used for controller design (Ant Colony optimization algorithm).
Investigation of RF emissions from wireless networks as a threat to avionic systems

The paper focuses on understanding and obtaining preliminary measurements of radiated field (RF) emissions of laptop/wireless local area network (WLAN) systems. This work is part of a larger research project to measure radiated emissions of wireless devices to provide a better understanding for potential interference with crucial aircraft avionics systems. A reverberation chamber data collection process is included, as well as recommendations for additional tests. Analysis of measurements from devices under test (DUTs) proved inconclusive for addressing potential interference issues. Continued effort is expected to result in a complete easily reproducible test protocol. The data and protocol presented here are considered preliminary.
Application of the 3D row action maximum likelihood algorithm to clinical PET imaging

True 3D reconstructions from fully 3D PET data can yield high-quality images but at a high computational cost. The 3D row action maximum likelihood algorithm (3D RAMLA) with 3D spherically-symmetric basis functions (blobs) has recently been modified to reconstruct multi-slice 2D PET data after Fourier rebinning (FORE) but still using 3D basis functions (2.5 D RAMLA). In this study both 2.5 D RAMLA and 3D RAMLA were applied to different patient and phantom PET data to assess their clinical performance. Whole-body scans acquired on the C-PET scanner were reconstructed with FORE+FBP, FORE+OSEM, and FORE+2.5 D RAMLA for various reconstruction parameters (blob radius and shape, relaxation parameter). The 3D Hoffman brain phantom scanned on the HEAD Penn-PET scanner was reconstructed with 3DRP and 3D RAMLA, as well as FORE+OSEM. The authors' results demonstrate improvement of the RAMLA compared to the popular reconstruction methods in terms of contrast recovery and noise, especially in regions of limited statistics.
Modélisation biomécanique du système reproductif féminin et du foetus humain pour la réalisation d'un simulateur virtuel d'accouchement

Le but de cette these est de realiser, au moyen d'un simulateur virtuel, un outil pour la formation a l'accouchement des jeunes obstetriciens. Ce simulateur est destine essentiellement a la formation des accouchements avec instruments (notamment en utilisant des forceps) : cette pratique augmentant considerablement les risques de blessures chez l'enfant au moment de l'extraction. La realisation de ce simulateur necessite le developpement d’un modele biomecanique complet du systeme genitale feminin ainsi que du foetus. Cette these est realisee en collaboration avec le laboratoire Ampere (INSA) qui travaille deja depuis quelques annees sur un simulateur haptique d'accouchement « BirthSIM ». A l'heure actuelle, les efforts de poussee presents dans BirthSIM sont d'ordre qualitatif. Cette these a, en plus de son objectif societal de formation, un interet scientifique, par la modelisation 3D du pelvis feminin ainsi que du foetus au moment de l'accouchement. La visualisation de cette simulation 3D permettra notamment de mieux comprendre les efforts engendres lors de l'accouchement, et ainsi d'ameliorer sa comprehension aupres des apprentis obstetriciens. Le but de cette these reside egalement dans l'obtention de valeurs fiables de l’effort total de poussee du foetus en fin d’accouchement afin de les repercuter dans le simulateur physique et ainsi de realiser un couplage entre le simulateur virtuel et le simulateur physique.
An Overview of the DARPA Autonomous Robotic Manipulation (ARM) Program (特集 マニピュレーション研究の最前線)

Circa 2010, manipulation systems required burdensome human operation and high-precision arms and hands, yet could not match the manipulation skills of a two-year old child. To address this situation, the U.S. Defense Advanced Research Projects Agency (DARPA) began funding the Autonomous Robotic Manipulation (ARM) program. The program’s goalsare to develop intelligent control of manipulators that perform subtasks on their own, and to reduce the cost of robot hardware for wider adoption. The ARM program comprises four tracks: software, low-cost hand, low-cost arm, and outreach. ARM-S, the software track, is developing new techniques for grasping and manipulation using local sensors for perception. ARM-H, the low-cost hand track, focused on design and development of low-cost dexterous, multi-fingered robot hands. The low-cost arm track is addressing a lowcost, dual-use robot/prosthetic application. The outreach track is providing the public with an opportunity to interact with the ARM technology. This paper describes recent work in both ARM-S and ARM-H.
