We address a natural question in average-case complexity: does there exist a language L such that for all easy distributions D the distributional problem (L,D) is easy on the average while there exists some more hard distribution D′ such that (L,D′) is hard on the average? We consider two complexity measures of distributions: complexity of sampling and complexity of computing the distribution f...
In this study, in order to simulate the monthly flow of the Khorramabad River, the time series of this river was decomposed into three levels using the wavelet of Daubechies-3, during the period of 1955-2014. Based on this, it was found that there is a Non-uniform noise that includes two periods of time in this signal, with the October 2008 border which required that the signal be become non-un...
We consider the problem of modulating the value of a parameter onto a band-limited signal to be transmitted over a continuous-time, additive white Gaussian noise (AWGN) channel, and estimating this parameter at the receiver. The performance is measured by the mean power-α error (MPαE), which is defined as the worst-case α-th order moment of the absolute estimation error. The optimal exponential...
Background: A pressure ulcer is a complication related to the need for the care and treatment of primarily disabled and elderly people. With the decrease of the blood flow caused by the pressure loaded, ulcers are formed and the tissue will be wasted with the passage of time.Objective the aim of this study was to construct blood flow monitoring system on the heel tissue which was under external...
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
