Frequency evaluation for adapted peer methods

islanding detection methods for microgrids

امروزه استفاده از منابع انرژی پراکنده کاربرد وسیعی یافته است . اگر چه این منابع بسیاری از مشکلات شبکه را حل می کنند اما زیاد شدن آنها مسائل فراوانی برای سیستم قدرت به همراه دارد . استفاده از میکروشبکه راه حلی است که علاوه بر استفاده از مزایای منابع انرژی پراکنده برخی از مشکلات ایجاد شده توسط آنها را نیز منتفی می کند . همچنین میکروشبکه ها کیفیت برق و قابلیت اطمینان تامین انرژی مشترکان را افزایش ...

Evaluation of Similarity Searching Methods for Music Data in Peer-to-Peer Networks

In this paper, we focus on similarity searching for similar acoustic data over unstructured decentralised P2P networks. Similarity is measured in terms of time warping, which can cope with distortion that is naturally present when query-by-content is performed. We propose a novel framework, which takes advantage of the absence of overhead in unstructured P2P networks and minimises the required ...

Mobile Peer-to-peer Frequency-hopping Communications

The potential pe~ormance of mobile peer-to-peer frequencyhopping communication systems in multiple-access networks is studied. Through analysis and simulation, the effects of Rayleigh fding, shadowing, spectral splattec the number offiequency channels, spatial diversity, and thermal noise are examined.

Adapted Bases of Time-frequency Local Cosines

We develop and analyze a best basis algorithm for orthonormal bases of local cosines which satisfy a uniform bound on their time-frequency concentration. All waveforms are obtained from three elementary window functions by shifts, rescaling, and modulation. For a discrete signal of length N, the complexity is of order N(logN) 2 .
