Form the past several decades' noise cancellation in speech signal gains researchers' attention. Several techniques were developed for noise cancellation among them optimal wiener filter can be the one of the most fundamental approach for noise cancellation. Later on adaptive filter was introduced to attain better performance. This paper shows the capacity of wiener filter and adaptiv...

the distally based sural fasciocutaneous flap has become a main part of the reconstruction of the lower leg, heel and foot. however, perfusion problems and venous congestion have been reported. over the past decade, several flap modifications have been reported to improve flap viability and to solve a myriad of reconstructive needs. the purpose of this paper is to describe our experience in har...

This paper explains about the mud for CDMA and compares different techniques available in the same field and comes out with the most effective approach. A brief explanation about interference cancellation, decorrelator mud and successive interference cancellation have been emphasized

closure of fascia after transverse rectus abdominis musculocutaneous (tram) flap has usually been performed with direct closure or synthetic material. the dermal autograft was removed from zone iv of flap was an alternative to reinforce fascial closure. the dermal autograft was used in 34 patients after tram harvest for breast, head and neck reconstruction and prolene mesh was used in 42 other ...

The success of awake craniotomies relies on the patient's performance of function-specific tasks that are simple, quick, and reproducible. Intraoperative identification of visuospatial function through cortical and subcortical mapping has utilized a variety of intraoperative tests, each with its own benefits and drawbacks. In light of this, we developed a simple software program that aids in pr...

Analog systems to achieve active noise cancellation in headphones were designed and implemented. Our project addresses two distinct technqiues feed forward and feedback systems. The work up to mid-semester, which was focused mainly on a feed-forward system with the motivation of developing a clip-on platform for generic earphones, is presented briefly. Limitations of this approach that lead to ...

Echo in the telephone network is a well-known phenomenon -long delays and noticeable echo may create significant or even unbearable disturbance in a telephone conversation. Echo cancellation is a technique to reduce the echo to an acceptable level. In fact, network echo canceller is considered as the single most critical element impacting overall voice quality in typical communication networks....
