The quadratic-phase Fourier transform (QPFT) has gained much popularity in recent years because of its applications image and signal processing. However, the QPFT is inadequate for localizing spectrum, which required some applications. In this paper, wave packet (QP-WPT) proposed to address problem, based on (WPT) QPFT. Firstly, we propose definition QP-WPT give relation with windowed (WFT). Se...

A deadlock in a packet switching network is state which one or more messages have not yet reached their target, cannot progress any further. We formalize three different notions of the context networks, to we refer as global, local and weak deadlock. establish precise relations between these notions, prove they characterize sets deadlocks. Moreover, implement checking freedom networks using sym...
