Abstract The functionally graded plates (FGP) with two new porosity distributions are examined in this paper. In work the plate is modeled using higher-order shear deformation principle. correction variables neglected. To evaluate equations of motion, Hamilton method will be used herein. Therefore, free vibration analysis FG developed work. For porous smart simply-supported sides, natural frequ...

in this study, the spatial distribution of overwintered adults of sunn pest, eurygaster integriceps puton, was investigated by using dispersion parameters and indices, mathematical distribution, and regression techniques in rainfed wheat fields by sample size of 1 m2 in 2009 and 2010. the dispersion parameters including: mean-variance test and clumping parameter () showed that the overwintered ...

Optimal reservoir management requires reliable reservoir performance forecasts with as little uncertainty as possible. There is a need for improved techniques for dynamic data intergration to construct realistic reservoir models by using geostatistical techniques. This paper gives a method to create porosity models that honor interpreted pore volumes from well test data. Well porosity data, sei...

The analysis of a flow pattern in cerebral aneurysms and the effect of strut shapes and stent porosity in 2D and 3D model are presented in this paper. The efficiency of a stent is related to several parameters, including porosity and stent strut shapes. The goal of this paper is to identify numerically how the stent strut shape and the porosity affect the hemodynamics properties of the flow ins...

A family of novel broadcast encryption schemes based on probabilistic key pre-distribution are proposed, that enable multiple sources to broadcast secrets, without the use of asymmetric cryptographic primitives. A comprehensive analysis of their efficiencies and performance bounds are presented. The paper also suggests a framework for applications of broadcast encryption, depending on 1) the re...

In the present work, the mathematical model of a homogeneous, isotropic thermoelastic double porous micro-beam, based on the Euler-Bernoulli theory is developed in the context of Lord-Shulman [1] theory of thermoelasticity. Laplace transform technique has been used to obtain the expressions for lateral deflection, axial stress, axial displacement, volume fraction field and temperature distribut...

Introduction And Geologic Overview The Upper Jurassic (Oxfordian) Smackover Formation is a stratigraphically complex carbonate formation, and a major producer of hydrocarbons in the northeastern Gulf of Mexico (Baria et al., 1982; Salvador, 1991). The main reservoir facies in the Smackover Formation are the microbial reefs, which were formed in a gently sloping to distally steepened carbonate r...

The petrophysical analysis of the early Eocene Sui Main Limestone (SML) has been conducted in Kharnhak-1 well for the prospect of the hydrocarbon exploration of the Khairpur-Jacobabad High, Middle Indus Basin, Pakistan. The petrophysical analysis of SML is carried out on the basis of well logs including gamma ray, spontaneous potential, resistivity, neutron, and density logs. These analyses lea...

The modern engineering structures require the advanced engineering materials to resist the high temperatures and to provide high stiffness. In particular the functionally graded porous materials (FGPMs) introduced are expected to have these desired properties, consequently eliminating local stress concentration and de-lamination. In the present paper, a new shear strains shape function is chose...
