A new effective and fast minimization approach completely based on the physical theory is proposed for protein design. The sequence space is essentially searched according to the Boltzmann distribution. In this approach, the relative entropy is used as a minimization object function. The method has been tested on an off-lattice model of proteins and the results are better than those obtained fr...

We give a program describing the pervasiveness of the short-time Fourier transform (STFT) in a host of topics including the following: waveform design and optimal ambiguity function behavior for radar and communications applications; vector-valued ambiguity function theory for multi-sensor environments; finite Gabor frames for deterministic compressive sensing and as a background for the HRT co...

In this paper, we introduce an alternative approach to reasoning about action. The approach provides a solution to the frame and the ramification problem in a uniform manner. The approach involves keeping a (syntax-based) model of the world that is updated when actions are performed. Our approach is similar to the STRIPS system in which formulas are deleted and added as effects of an action. Th...

The solution to the problem of optical or electromagnetic-wave scattering from perfectly conducting rough surfaces modeled by a multiscale fractal function is generalized to the case of relative uniform translating motion with respect to the observer. The presence of motion can be treated by the relativistic frame hopping method by means of plane-wave simplification techniques, since the soluti...

In this study, a system of discontinuous rigid blocks is employed to simulate the possible damage mechanisms in unreinforced masonry (URM) façades and load-bearing frame systems subjected settlement using discrete element method (DEM). First, modeling strategy validated utilizing available experimental results presented literature. Once there good agreement between computational models findings...

In this study, we investigate analytical treatment of three dimensional MHD viscous flow in a rotating frame. The flow is generated due to uniform stretching of a sheet in x direction. Analytic solution is obtained through peturbation method after transforming the governing partial differential equation to ordinary differential equation using suitable similarity transformations. Graphs are plot...

It is proved that in classical electrodynamics the uniform rectilinear motion of charged " rigid " sphere with self-action (Sommerfeld model) is stable. 03.50.De In classical electrodynamics long time ago in Sommerfeld works [1, see also 2] was derived the expression of self-force acting on " nonrelativistically rigid charged sphere " , i.e sphere with radius a, its center moving along trajecto...

In this paper we present a new approach to reason about actions and causation which is based on a conditional logic. The conditional implication is interpreted as causal implication. This makes it possible to formalize in a uniform way causal dependencies between actions and their immediate and indirect effects. Furthermore, this new approach provides a natural formalization of concurrent actio...

Permutation source codes are a class of structured vector quantizers with a computationally-simple encoding procedure. In this thesis, we provide two extensions that preserve the computational simplicity but yield improved operational rate–distortion performance. In the first approach, the new class of vector quantizers has a codebook comprising several permutation codes as subcodes. Methods fo...

the available shear correction factors have mainly been developed for homogeneous isotropic plates and/or assuming that no shear tractions are imposed on the top and bottom surfaces of the plate. in the present research, a more general case of a circular functionally graded plate subjected to non-uniform normal and shear tractions at the top and bottom surfaces is considered. these non-uniform ...
