Harmful Aids

در این مقاله بیماری ایدز با تابلوی بالینی پیچیده خود معرفی خواهد شد. ویروس HIV یا نقص ایمنی انسانی، مانند سایر ویروس ها، جهت چرخه حیات و تولید مثل خود به محیط درونی سلول نیاز دارد. میزبانان HIV در بدن بطور عمده سلول های سیستم ایمنی شامل لنفوسیت های T، سلول های کمک کننده T و مونوسیت ها می باشند . ویروس بصورت مؤثر سلول ها را بکار گرفته و از آن ها به عنوان ماشینی جهت اجرای دستورات ژنتیکی خود استفا...

A Low-Voltage CMOS Filter for Hearing Aids using Dynamic Gate Biasing

In this paper we discuss the design of a low-voltage (1.5V), continuous-time, biquadratic CMOS filter based on Dynamic Gate Biasing (DGB). We begin by discussing the filter’s structure and its tuning mechanism. The filter uses transconductanceC cells and implements low-pass, bandpass and highpass transfer functions. The transconductances are tuned using the gate voltages of MOSFETs operating in...

Speech enhancement with multichannel Wiener filter techniques in multimicrophone binaural hearing aids.

This paper evaluates speech enhancement in binaural multimicrophone hearing aids by noise reduction algorithms based on the multichannel Wiener filter (MWF) and the MWF with partial noise estimate (MWF-N). Both algorithms are specifically developed to combine noise reduction with the preservation of binaural cues. Objective and perceptual evaluations were performed with different speech-in-mult...
