Averaging is one of the basic methods of statistical analysis of experimental data where the response of the system is periodic or quasi-periodic. As long as the noise are Gaussian, the standard averaging leads to good results and effective noise reduction. However, when the distortions have impulsive nature, then such an approach leads to a deterioration of the system. In this case the robust ...

in recent years, emotion dysregulation and anxiety sensitivity have been introduced of the most effective factors in sleep disturbance. the purpose of this study was to examine emotion dysregulation and anxiety sensitivity as potential contributor to sleep problems in students. the statistical population of this research consisted of all the bu-ali sina university’s students in the academic yea...

This paper presents a new method for suppressing noise in video sequences. The filter is an extension of the sigma filter. It uses local measurements to obtain noise reduction while preserving the image edges and details. By using a special defined weighting function, this filter can reduce both Gaussian and impulse noise effectively.

This paper describes a new method for design of linear phase finite impulse response (FIR) filters. This new approach, based on the ε-insensitive loss function, allows the design process to take into account not only constraints specified in the frequency domain, but also constraints on the output, time domain, signal. The performances of the proposed approach are shortly illustrated with a des...

Recent studies indicate that the extent of perceived motion smear is attenuated asymmetrically during smooth pursuit eye movements, based on the relative directions of the target and eye motion. We conducted two experiments to determine if the reduction of perceived smear during pursuit might be associated with an acceleration of the temporal impulse response function (TIRF). In Experiment 1, t...

Background: The purpose of this study was to calculate and compare the specificity and sensitivity of impulse oscillometry (IOS) as a new technique in the detection of airways dysfunction by means of a simple pulmonary function test in chemical warfare injured cases suffering from respiratory diseases. Methods: The study was performed prospectively in 100 patients, who complained of dyspnea as ...
