A 32nm logic technology for high performance microprocessors is described. 2 generation high-k + metal gate transistors provide record drive currents at the tightest gate pitch reported for any 32nm or 28nm logic technology. NMOS drive currents are 1.62mA/um Idsat and 0.231mA/um Idlin at 1.0V and 100nA/um Ioff. PMOS drive currents are 1.37mA/um Idsat and 0.240mA/um Idlin at 1.0V and 100nA/um Io...
این پایان نامه یک تکنیک جدید برای تخمین سرعت باد با استفاده از شبکه عصبی پیشنهاد می دهد، به این صورت که تلفات سیستم توربین بادی با یک روش جدید برای تخمینگر عصبی سرعت باد مدل می شوند. ابتدا عملکرد دو نوع تخمینگر عصبی سرعت باد 1) شبکه عصبی پیش خور پرسپترون چند لایه(mlp) 2) شبکه عصبی پس خور انعکاس حالت (esn) برای کنترل حداکثر نقطه توان توربین بادی بدون سنسور برای دو حالت 1) بدون در نظر گرفتن جریان...
A digital signal processor (DSP) based voice communication system for divers with a 2400 bitls transmission rate is described. Each speech signal frame is analysed using linear predictive coding (LPC) and the essential parameters such as amplitude, pitch period and digital filter coefficients are extracted. These parameters are transmitted through a water channel at a rate of 2400 bitls by empl...
Recently, a method for joint extraction of pitch and location information from two-channel recordings has been introduced. This framework offers a new, natural representation of all acoustic sources in the auditory scene, and has potential to be used as front-end in applications such as advanced tracking of multiple speakers in conference rooms. In this paper, we explore basic properties of thi...
As cochlear implant patients achieve greater success in understanding speech it is important to examining more complex hearing tasks. One logical step is to begin exploring some of the problems associated with music perception. Because music requires relatively precise pitch information, it can present unique challenges to current speech-oriented implant designs, which are limited in the amount...
On August 7, 2003 the Cluster spacecraft moved through the dayside magnetosphere. The energetic particle spectrometer on board Cluster provided measurements of an extensive range of energy. Besides, satellite measurements of geomagnetic field showed a gradient magnetic field. It is known that an inhomogeneity of the magnetic field leads to a drift of charged particles. In this paper, the drift ...
Orthodontic miniscrews are widely used as temporary anchorage devices to facilitate orthodontic movements. Miniscrew loosening is a common problem, which usually occurs during the first two weeks of treatment. Macrodesign can affect the stability of a miniscrew by changing its diameter, length, thread pitch, thread shape, tapering angle and so on. In this study, a 3-D finite element analysis wa...
This paper presents a novel method for identifying regions of speech in the kinds of energetic and highly-variable noise present in ‘personal audio’ collected by body-worn continuous recorders. Motivated by psychoacoustic evidence that pitch is crucial in the perception and organization of sound, we use a noise-robust pitch detection algorithm to locate speech-like regions. To avoid false alarm...
