Speech constitutes much of the communicated information; most other perceived audio signals do not carry nearly as much information. Indeed, much of the non-speech signals maybe classified as ‘noise’ in human communication. The process of separating conversational speech and noise is termed voice activity detection (VAD). This paper describes a new approach to VAD which is based on the Wavelet ...

This study deals with the design of a near-field wireless power transfer (WPT) system applied to left ventricular assist device (LVAD) treat patients heart-failure problems. An LVAD is an implanted electrically driven pump connected heart and traditionally powered by batteries external human body via percutaneous driveline cable. The main challenge wirelessly powering deep in relatively high ef...

A Biometric system is essentially a pattern recognition system that makes use of biometric traits to recognize individuals. Systems which are built upon multiple sources of information for establishing identity which are known as multimodal biometric systems can overcome some of the limitations like noisy captured data, intra class variations etc... In this paper a Bi modal biometric system of ...

In order to enhance the tolerance of frequency misalignment and solve amplitude-bandwidth limitation issue traditional linear resonance wireless power transfer (WPT) system, this paper proposes a non-linear WPT (NLR-WPT) system which is mainly composed high supply, primary resonator, secondary load. Such resonator can be implemented with passive capacitor magnetic saturation inductor, it descri...

ultrasound imaging is a popular and noninvasive tool frequently used in the diagnoses of liver diseases. a system to characterize normal,fatty and heterogeneous liver, using textural analysis of liver ultrasound images, is proposed in this paper. the proposed approach isable to select the optimum regions of interest of the liver images. these optimum regions of interests are analyzed by two lev...

In this paper, we investigate multi-dimensional chaotic signals with respect to wireless power transfer (WPT). Specifically, analyze a Lorenz-based signal under WPT framework. By taking into account the nonlinearities of energy harvesting process, closed-form analytical expressions for average harvested are derived. Moreover, practical limitations high amplifier (HPA) at transmitter also taken ...

The aim of the present study was to determine the effect of patellar taping (PT) on landing characteristics of the vertical ground reaction force (VGRF) and on flight time during a counter movement jump (CMJ). Eleven healthy male subjects (age: 31.1 ± 4.2 years) volunteered for the study. Each subject performed six CMJs under two different jumping conditions: with PT and without PT (WPT). The o...

The aim of the present study was to determine the frequency of alteration in warm perception thresholds (WPT), cold perception thresholds (CPT) and the warm and cold perception interval (WCPI) in leprosy-suspected skin lesions, and to determine if these tests could assist in the diagnosis of leprosy. Tests were conducted using a thermal sensory analyser TSA-2001 (Medoc Ltd, Israel) and the meth...

Recently, research has been actively conducted to overcome various challenges observed in wireless power transfer (WPT) technology. However, as additional techniques are implemented, the complexity and cost of WPT systems increased. Therefore, there is a need for new method that can shortcomings existing This paper presents metal surface guided-wireless (MSG-WPT) system applications with multip...

Consider a complex symplectic manifold X and the algebroid stack WX of deformation-quantization. For two regular holonomic WXmodules Li (i = 0, 1) supported by smooth Lagrangian submanifolds, we prove that the complex RHom WX (L1,L0) is perverse over the field Wpt and dual to the complex RHomWX(L0,L1).
