Background: The aim of the present study is to compare time perception among drug addicts and controls. Methods: 30 drug addicts were selected, and 30 non-addict individuals were selected as the control group. The two groups performed three tests of time reproduction, time estimation, and time discrimination. Findings: There was a significant difference between the addicts group and the control...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
abstract angstrom-prescott equation is one of the most commonly used methods for the estimation of global solar radiation (rs) based on sunshine hours. the critical step in the application of this method's is the calibration of its coefficients for each region. although the coefficients of the equation have been calibrated in different parts of the world, the effect of different time scales has...
In this paper, we improve the performance of the TiR-UWB communication systems with the non-ideal estimation of the channel. Time Reversal (TiR) technique is an effective and simple method for data transmission in extremely multipath indoor UWB channels that mitigates the complexity of receiver by its own time focusing feature. Although, TiR method has the suitable performance, but it is sensit...
today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...
The ARTFIMA model applies a tempered fractional difference to the standard ARMA time series. This paper develops parameter estimation methods for the ARTFIMA model, and demonstrates a new R package. Several examples illustrate the utility of the method.
in this paper an efficient three- stage algorithm is developed for software production cost and time estimation. first stage includes a hybrid model composed of cocomo and function points methods to increase estimation accuracy. second stage encompasses paired comparisons matrix of analytical hierarchy process to determine amount of any resources consumed in each step of software production by ...
