In many applications of speech processing the noise reveals some specific features. Although the noise could be quite broadband, there are a limited number of dominant frequencies, which carry the most of its energy. This fact implies the usage of narrow-band notch filters that must be adaptive in order to track the changes in noise characteristics. In present contribution, a method and a system for noise suppression are developed. The method uses adaptive notch filters based on second-order Gray-Markel lattice structure. The main advantages of ....etc

Definition
Space-Time Adaptive Processing (STAP) refers to a class of signal processing techniques used to process returns of an antenna array radar system. It enhances the ability of radars to detect targets that might otherwise be obscured by clutter or jamming.
. The output of STAP is a linear combination or weighted sum of the input signal samples .The adaptive in STAP refers to the fact that STAP weights are computed to reflect the actual noise, clutter and jamming environment in which the radar finds itself. The space in STAP refer ....etc

A GPU is a circuit board with a dedicated processor designed specifically to handle intense computational requirements of displaying graphics. These were earlier known as 3D accelerators, because the main job of these units deals with objects represented in 3 dimensions. There are various applications that require a 3D world to be simulated as realistically as possible on a computer screen. These include 3D animations in games, movies and other real world simulations.

It takes a lot of computing power to represent a 3D world due to the great ....etc

There are a growing number of people who want to use remotely sensed data and GIS data. What is needed is a large-scale processing and storage system that provides high bandwidth at low cost.

Scalable computing clusters, ranging from a cluster of (homogeneous or heterogeneous) PCs or workstations, to SMPs, are rapidly becoming the standard platforms for high-performance and large-scale computing. To utilize the resources of a parallel computer, a problem had to be algorithmically expressed as comprising a set of concurrently executing sub-p ....etc

Introduction

Uncompressed multimedia data requires considerable storage capacity and transmission bandwidth. Despite rapid progress in mass storage density processor speeds and digital communication system performance, demand for data storage capacity and data transmission bandwidth continues to outstrip the capabilities of available technologies. The recent growth of data intensive multimedia-based web applications have not only sustained the need for more efficient ways to encode signals and images but have made compression of such signal ....etc

Large-screen, high-brightness electronic projection displays serve four broad areas of application: (1) electronic presentations (e.g., business, education, advertising), (2) entertainment (e.g., home theater, sports bars, theme parks, electronic cinema), (3) status and information (e.g., military, utilities, transportation, public, sports) and (4) simulation (e.g., training, games). The electronic presentation market is being driven by the pervasiveness of software that has put sophisticated presentation techniques (including multi ....etc

The biggest obstacle to the multimedia revolution is digital obesity. This is the blot that occurs when pictures, sound and video are converted from their natural analog form into computer language for manipulation or transmission. In the present explosion of high quality data, the need to compress it with less distortion of data is the need of the hour. Compression lowers the cost of storage and transmission by packing data into a smaller space. One of the hottest areas of advanced form of compression is wavelet compression. Wavelet Video ....etc
