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

Imaging technology has a rich history that began thousands of years ago. The reflection from a pool of still water or a shiny metal surface was arguably the first imaging method routinely used by mankind. With the advent of lenses, many other novel forms of optical imaging emerged, including telescopes and microscopes.

Using a lens, a pinhole camera, and a sensitized pewter plate, Ni?pce was the first person to permanently record an image. Optical photography and other forms of optical imaging have since become commonplace.

Of course, im ....etc

Introduction


Web application designing has by far evolved in a number of ways since the time of its birth. To make web pages more interactive various techniques have been devised both at the browser level and at the server level. The introduction of XMLHttpRequest class in the Internet Explorer 5 by Microsoft paved the way for interacting with the server using JavaScript, asynchronously. AJAX, a shorthand for Asynchronous Java And XML, is a technique which uses this MLHttpRequest object of the browser features plus the Document Object Mod ....etc

Sensor networks are widely being used for sense-response applications. The role of the sensor nodes in such applications is to monitor an area for events of interest and report the occurrence of the event to the base-station. The receipt of the event at the base-station is followed by a prompt physical response. An example of a sense-response application is the detection of fires in a forest. The sensor nodes report the occurrence of a fire upon which fire trucks are immediately dispatched to the location of the fire. Other examples of sense-re ....etc

Definition
An Artificial Neural Network (ANN) is an information-processing paradigm that is inspired by the way biological nervous systems, such as the brain, process information. The key element of this paradigm is the novel structure of the information processing system. It is composed of a large number of highly interconnected processing elements (neurons) working in unison to solve specific problems. ANNs, like people, learn by example. An ANN is configured for a specific application, such as pattern recognition or data classification, thr ....etc

An Inverter is simply an electronic device that converts low voltage DC battery power 230 volts AC (Alternating Current) electrical power. They are used in applications ranging from microwaves laptops to satellite systems X-Ray machines etc.

Most industrial applications require high frequency high voltage power supply. These increased power requirements have lead to significant development in inverted technology.


Significant improvements have been made to the traditional pulse width modulations (PWM) Inverters to make power distributio ....etc
