آنچه در سیستم‎های مخابرات سیار تا کنون مرسوم بوده، این است که در ایستگاه پایه، از آنتن‎های همه جهته و یا از تکنولوژی قطاع‎بندی سلول، استفاده کنند. این روش کار منجر به هدر رفتن توان می‎شود چرا که توان در جهات دیگری، غیر از جهت مورد نظر فرستاده می‎شود. اما در روشهای جدید، با استفاده از آنتن‎های هوشمند، و الگوریتم‎های خاصی که در قسمت پردازشی آنها به کار گرفته می‎شود، می‎توان جهت ورود سیگنال (doa) ...

previously studies have shown that music can be used to increase the time to engage in physical activity but music's role in controlling the intensity of pa has been studied less. the sensorimotor synchronization (sms), the coordination of rhythmic movement with rhythmic sensory stimuli method, seems to have enough potential and can be applied instead of the previous method for ordinary pe...

An algorithm that discovers the themes, motives and other perceptually significant repeated patterns in a musical work can be used, for example, in a music information retrieval system for indexing a collection of music documents so that it can be searched more rapidly. It can also be used in software tools for music analysis and composition and in a music transcription system or model of music...

This paper studies the problem of line spectral estimation in the continuum of a bounded interval with one snapshot of array measurement. The single-snapshot measurement data is turned into a Hankel data matrix which admits the Vandermonde decomposition and is suitable for the MUSIC algorithm. The MUSIC algorithm amounts to finding the null space (the noise space) of the Hankel matrix, forming ...

In this paper, we present our evaluations in using blind single channel dereverberation on music signals. The target material is heavily reverberated and dynamic range compressed polyphonic music from several genres. The applied dereverberation method is based on spectral subtraction regulated by a time-frequency domain linear predictive model. We present our results on enhancing music signal q...

Introduction: Listening to music during physical activity reduces the perceived stress on body. Hence, this study aimed to evaluate the effects of music genre and sound pressure level on calorie consumption and physical performance of students during treadmill tests. Methods: In this cross-sectional study, 27 students were randomly selected. A demographic questionnaire, Borg Rating of Percei...

Introduction: This randomized clinical trial (RCT) was conducted to evaluate whether use of music could reduce the pain and duration of labor. Methods: Between 2010 and 2011, a total of 99 women at 38 weeks or greater with spontaneous labor were randomized to fast music, slow music, and control groups. Labor pain was assessed on a visual analogue scale (VAS) at beginning of the active phase an...
