The present study adds to the knowledge of free vibration antisymmetric angle-ply annular circular plates with variable thickness for simply supported boundary conditions. differential equations in terms displacement and rotational functions are approximated using cubic spline approximation. A generalized eigenvalue problem is obtained solved numerically an eigenfrequency parameter associated e...
introduction: recent studies have shown acute cardioprotective effects of cyclosporine. the aim of the present study was to determine the protective role of cyclosporine on the model simulated the rotational nodal arrhythmia (avnrt) by using extracellular field potential recordings of isolated atrioventricular-node (av-node) of rabbit. methods: this study was performed on isolated double-perfus...
Introduction: Developmental changes in atrioventricular nodal conduction time and refractoriness have been shown in several studies. Prevalence of atrioventricular nodal reentrant tachycardia (AVNRT) is clearly age-dependent. The purpose of this study was to determine developmental changes of basic and frequency-dependent electrophysiological properties of the atrioventricular node (AV-node)...
in this paper, multi-objective uniform-diversity genetic algorithm (muga) with a diversity preserving mechanism called the ε-elimination algorithm is used for pareto optimization of 5-degree of freedom vehicle vibration model considering the five conflicting functions simultaneously. the important conflicting objective functions that have been considered in this work are, namely, vertical accel...

This research paper proposes a new triangular cylindrical finite element for static and free vibration analysis of structures. The formulation the proposed is based on deep shell theory uses assumed strain functions instead displacement functions. satisfy compatibility equations. possesses only five necessary degrees freedom each three corner nodes. element's field, which contains higher-order ...
