In this paper a generalized postfilter algorithm design issues are presented. This postfilter is used to jointly suppress late reverberation, residual echo, and background noise. When residual echo and noise are suppressed, the best result obtains by suppressing both interferences together after the Acoustic echo cancellation (AEC). The main advantage of this approach is that the residual echo ...

Echocardiography is an essential investigation for cardiology services, with its activity directly correlated to cardiothoracic activity, morbidity, and mortality. Much research has been undertaken show that most New Zealand echo departments are under performing. Three key areas highlighted in this presentation: training, allocated scan times, sonographer call duties. proposals make the three a...

An uncemented stem has been used successfully in total hip arthroplasty for 2 decades, and some implants have been updated. The authors have used second-generation uncemented proximal porous coating stems, the Echo Bi-Metric Full Proximal Profile stem (Echo FPP; Biomet, Warsaw, Indiana) and the Echo Reduced Proximal Profile stem (Echo RPP; Biomet). This article reports short-term outcomes with ...
