In this paper an estimator of speech spectrum for speech enhancement based on Laplacian Mixture Model has been proposed. We present an analytical solution for estimating the complex DFT coefficients with the MMSE estimator when the clean speech DFT coefficients are mixture of Laplacians distributed. The distribution of the DFT coefficients of noise are assumed zero-mean Gaussian.The drived MMSE...
OBJECTIVE To compare the clinical Allen test, preoperative Doppler ultrasonography, and intraoperative surgical Allen test with postoperative clinical findings in reconstruction of complex head and neck defects using radial forearm free flaps. DESIGN, SETTING, AND PATIENTS Retrospective review of 143 consecutive patients who underwent radial forearm free flap reconstruction from January 1, 19...
Facebook is the most dominant social networking site in colleges right now. According to a recent study done by OnlineEducation.net on college students' use of social media in the U.S., 96 percent of college students use Facebook. In addition, 75 percent of college students report that they want to collaborate online with each other via Facebook (Andrew, 2011). Because of the popularity of Face...

Methods During 2009, 167 MRSA-infected and 25766 MRSAuninfected control patients were included in a multistate model where occurrence of MRSA infection was the time-dependent exposure and discharge or death was the study endpoint. Infections were stratified by anatomical site. Excess LoS was extracted computing the Aalen-Johansen estimator of the matrix of transition probabilities. 95% confiden...
در این تحقیق اثر تغییر اقلیم بر مراحل فنولوژی گندم در کرمانشاه بررسی شده است در ابتدا رخداد تغییر اقلیم برای دوره پایه (2008 تا 1988) در منطقه با استفاده از دو آزمون من-کندال و sens estimator slope ارزیابی شد نتایج نشان داد که متوسط دمای سالانه دارای روند افزایشی و همچنین متوسط بارندگی های سالانه دارای روند کاهشی می باشد. در ادامه هم با ریز مقیاس نمایی آماری داده های خروجی مدل ccsm4 با استفاده ...
can address every future situation effectively, so designers must be prepared to appreciate design situations subtly and with discipline, invent and re-invent processes, and take personal responsibility for the effects of their designs rather than handing off responsibility for quality outcomes to a single process or theory (Nelson & Stolterman, 2003). Designers act as human instruments, analog...
Introduction In classical methods of statistics, the parameter of interest is estimated based on a random sample using natural estimators such as maximum likelihood or unbiased estimators (sample information). In practice, the researcher has a prior information about the parameter in the form of a point guess value. Information in the guess value is called as nonsample information. Thomp...
The underconfidence-with-practice (UWP) effect is a common finding in calibration studies concerned with judgments of learning (JOLs) elicited on a percentage scale. The UWP pattern is present when, in a procedure consisting of multiple study-test cycles, mean scale JOLs underestimate mean recall performance on cycle 2 and beyond. Although this pattern is present both for items recalled and unr...
