We present free-space transparency, a method that renders unimportant regions of a window as transparent. This allows users to view screen content that lies beneath these regions. By maximizing the amount of simultaneously visible content, while keeping window sizes and locations constant, users can be made more productive with minimal window layout manipulation.

This paper investigates the general problem of resource allocation for mitigating channel fading effects in Free Space Optical (FSO) communications. The is modeled as constrained stochastic optimization framework, which covers a variety FSO scenarios involving power adaptation, relay selection and their joint allocation. Under this we propose two algorithms that solve problems. We first present...

the risk free rate of return plays a main role in financial economic theory and financial markets. due to prohibition of interest in islamic countries there is no specific financial instrument with risk free rate of return as a criterion for measuring the risk free rate of market. we apply the kalman filter to estimate this variable for financial markets in iran. the technique is based on a sta...

a new approach for analyzing cracked problems in 2d orthotropic materials using the well-known element free galerkin method and orthotropic enrichment functions is proposed. the element free galerkin method is a meshfree method which enables discontinuous problems to be modeled efficiently. in this study, element free galerkin is extrinsically enriched by the recently developed crack-tip orthot...

It is an open challenge to analyze the crystalline color superconducting phases that may arise in cold dense, but not asymptotically dense, three-flavor quark matter. At present the only approximation within which it seems possible to compare the free energies of the myriad possible crystal structures is the Ginzburg-Landau approximation. Here, we test this approximation on a particularly simpl...
