Purpose: The aim of present research was determine the modeling of self-regulation based on cognitive flexibility with mediated role of psychological hardiness in students. Methodology: The present study was descriptive, correlational type. The research population was all secondary high school students of Tehran city in academic years of 2019-20, which from them 499 students were selected by s...

With increasing number of wireless devices like laptops, Wi-Fi Web Cams, network extenders, etc., a new kind of problems appeared, mostly related to poor Wi-Fi throughput or communication problems. In this paper an investigation on wireless networks and it’s saturation in Vilnius City and its surrounding is presented, covering the main problems of wireless saturation and network load during day...

In this paper, we address the problem of identifying the parameters of the nonminimum-phase FIR system from the cumulants of noisy output samples. The system is driven by an unobservable, zero-mean, independent and identically distributed (i.i.d) non-Gaussian signal. The measurement noise may be white Gaussian, colored MA, ARMA Gaussian processes, or even real noises. For this problem, two nove...

In [DG 891, the authors show that many results concerning the problem of efficient interpolation of k-sparse multivariate polynomials can be formulated and proved in the general setting of k-sparse sums of characters of abelian monoids. In this note we describe another conceptual framework for the interpolation problem. In this framework, we consider R-algebras of functions &i, . . . , &” on an...

In the present study, the combination of lattice Boltzmann and immersed boundary methods is used to simulate the motion and deformation of a flexible body. Deformation of the body is studied in microchannel with stenosis and the effect of the flexibility changes on its deformation is investigated. The obtained results in the present manuscript show that by increasing the elasticity modulus, the...

In this paper, a computationally simple approach for damage localization and quantification in beam-like structures is proposed. This method is based on using modal flexibility curvature (MFC) and particle swarm optimization (PSO) algorithm. Analytical studies in the literature have shown that changes in the modal flexibility curvature can be considered as a sensitive and suitable criterion for...
