in this paper, the effect of different boundary conditions on the free vibration analysis response of a sandwich plates is presented using higher order shear deformation theory. the face sheets are orthotropic laminated composite that follow the first order shear deformation theory (fsdt) based on rissners-mindlin (rm) kinematics field. based on energy method and hamilton's principle, the ...

This paper investigates the impact of urban spatial structure on the opportunities for people to participate in face‐to‐face activities. We make use of the Social Interaction Potential (SIP) metric, a tool to measure the average level of opportunity for people to engage in face‐to‐face activities given some basic constraints on their daily mobility patterns. Generally, this opportunity is a ref...

The Inspector/Executor is well-known for parallelizing loops with irregular access patterns that cannot be analyzed statically. The downsides of existing inspectors are that it is hard to amortize their high run-time overheads by actually executing the loop in parallel, that they can only be applied to loops with dependencies that do not change during their execution and that they are often spe...

The one-component plasma (OCP) represents the simplest statistical mechanical model of a Coulomb system. For this reason, it has been extensively studied over the last forty years. The advent of the integral equations has resulted in a dramatic improvement in our ability to carry out numerical calculations, but came at the expense of a physical insight gained in a simpler analytic theory. In th...

In this paper, a rectangular sandwich plate with a constrained layer and an electrorheological (ER) fluid core is investigated. The rectangular plate is covered an ER fluid core and a constraining layer to improve the stability of the system. The two outer layers of the sandwich structure are elastic. The viscoelastic materials express the middle layer behavior under electric field and small st...

This study explores the competing influences of different types of board interlocks on diffusion of a strategic initiative among a population of firms. We examine a broad social network of interlocking directors in U.S. firms over a period of 17 years and consider the likelihood that these firms will adopt a strategy of expansion into China. Results show that ties to adopters that unsuccessfull...

background: hepatitis b virus (hbv) infection is the most common cause of end-stage liver disease in iran. more than 70% of cases are negative for the hepatitis b e antigen (hbeag) and have a long-term response to antiviral therapy, as well as a high relapse rate after discontinuing lamivudine or interferon. these features could be due, in part, to genetic variation of the hbv genome. materials...
