Due to the recent surge in silicon demand for solar modules, thin-film photovoltaic (PV) modules have a potential penetrate market significant numbers. As an alternate candidate, thin film technologies PVs ability achieve better performance. The competing PV flexibility adapt any sort of curvature compared rigid cells (SCs). peculiar characteristics newer materials, stability issues, reflection...

In this paper we focus on a special class of commutative local‎ ‎rings called SPAP-rings and study the relationship between this‎ ‎class and other classes of rings‎. ‎We characterize the structure of‎ ‎modules and especially‎, ‎the prime submodules of free modules over‎ ‎an SPAP-ring and derive some basic properties‎. ‎Then we answer the‎ ‎question of Lam and Reyes about strongly Oka ideals fam...

We present an investigation through numerical analysis (FEM) of the solution contact problem in friction clutch systems during engagement manoeuver. The case high pressure between sliding elements a system (flywheel, and plate) has been also considered. A finite element model dry (single disc) to estimate distributions under different working conditions developed main findings are discussed. Fu...

The paper studies effective elastic properties of foam or cellular materials modeled by a set Gibson-Ashby open cells with regular irregular structures. Currently, there are many papers that present results studying using theoretical, numerical and experimental methods. However, these consider either lattices, single cell, representative volume models based not on the models. In this paper, in ...

Security focused OS (Secure OS) is attracting attention as a method for minimizing damage caused by various intrusions. Secure OSs can restrict the damage due to an attack by using Mandatory Access Control (MAC). In some projects, secure OSs for Linux have been developed. In these OSs, different implementation methods have been adopted. However, there is no method for easily evaluating the perf...

Current research in Intrusion Detection Systems (IDSs), targeted towards preventing computer attacks, is mainly focused on improving detection and reaction mechanisms, without preserving the protection of the system itself. This way, if an attacker compromises the security of the detection system, she may be able to disarm the detection or reaction mechanisms, as well as delete log entries that...

Let $ m , n in mathbb{N}$, $D$ be a division ring, and $M_{m times n}(D)$ denote the bimodule of all $m times n$ matrices with entries from $D$. First, we characterize one-sided submodules of $M_{m times n}(D)$ in terms of left row reduced echelon or right column reduced echelon matrices with entries from $D$. Next, we introduce the notion of a nest module of matrices with entries from $D$. We ...

G-frames are natural generalizations of frames which provide more choices on analyzing functions from frame expansion coefficients. First, they were defined in Hilbert spaces and then generalized on C*-Hilbert modules. In this paper, we first generalize the concept of g-frames to Hilbert modules over pro-C*-algebras. Then, we introduce the g-frame operators in such spaces and show that they sha...

The purpose of this paper was to see whether any significant relationship exists among EFL learners’ autonomy, left/right brain dominance, and reading comprehension of the Academic Reading and General Reading Modules of IELTS examination. To this end, 100 female EFL learners were randomly selected from those who were attending IELTS preparatory courses at a language school in Tehran. All partic...

We introduce the notions of T-dual Rickart and strongly T-dual Rickart modules. We provide several characterizations and investigate properties of each of these concepts. It is shown that every free (resp. finitely generated free) $R$-module is T-dual Rickart if and only if $overline{Z}^2(R)$ is a  direct summand of $R$ and End$(overline{Z}^2(R))$ is a semisimple (resp. regular) ring. It is sho...
