Two common approaches for estimating a linear trend are 1) simple linear regression and 2) the epoch difference with possibly unequal epoch lengths. The epoch difference estimator for epochs of length M is defined as the difference between the average value over the last M time steps and the average value over the first M time steps divided by N 2 M, where N is the length of the time series. Bo...

to know every phenomenon the first step is to know its root. hygiene and medicine have noble origin from the beginning of the recorded human history; in fact, they have been the milestone of human society. medical history will help us to know this background and roots and achaemenid period as a brilliant age of iranian heritage is meritorious to be studied. the present study is an attempt to fi...

In this work we study a special type of task scheduling referred to as epoch scheduling in a distributed server (processor) system. With this policy, processor queues are rearranged only at the end of predefined intervals. The time interval between successive queue rearrangements is called an epoch. The objective is to examine if epoch scheduling can perform close to STF method and achieve fair...
