We present several versions of Regularized Combined Field Integral Equation (CFIER) formulations for the solution of three dimensional frequency domain electromagnetic scattering problems with Perfectly Electric Conducting (PEC) boundary conditions. Just as in the Combined Field Integral Equations (CFIE), we seek the scattered fields in the form of a combined magnetic and electric dipole layer ...

A system of processes in which the interactions are solely through messages is often called loosely-coupled. Such systems are attractive from a programming viewpoint. They are designed by decomposing a specification into its separable concerns, each of which could then be implemented by a process; the operation of the system can be understood by asserting properties of the message sequences tra...

Scalar fields with inverse power-law effective potentials may provide a negative pressure component to the energy density of the universe today, as required by cosmological observations. In order to be cosmologically relevant today, the scalar field should have a mass mφ = O(10 −33eV), thus potentially inducing sizable violations of the equivalence principle and space-time variations of the cou...

In this paper a coupled problem of dynamic electroelasticity is investigated using the variational approach and the concept of generalized solutions. We derive a numerical procedure directly from the deenition of the generalized solution of the problem. We prove the convergence of the numerical scheme (with the second order in space-time) to the solution of the original problem from a class of ...

It is expected that the inflation paradigmwould be explained within superstring/Mtheory. The theory predicts that spacetime dimension is greater than four. Since observable spacetime dimension is four, it is thought that the extra dimensions would be compactified within Planck scale. Recently, it has been pointed out that it is possible to find cosmological solutions which exhibit a transient p...

We derive the asymptotic traveling-wave solutions of the nonlinear 1-dimensional BalitskyKovchegov QCD equation for rapidity evolution in momentum-space, with 1-loop running coupling constant and equipped with the Balitsky-Kovchegov-Kuraev-Lipatov kernel at next-to-leading logarithmic accuracy, conveniently regularized by different resummation schemes. Traveling waves allow to define “universal...

in this work we investigate the thermal entanglement between two-level atoms and photons in a nonlinear cavity. we consider intensity-dependent couplings and calculate the negativity, as a measure of atom-photonentanglement. the cavity is assumed to be at a temperature t, so that all number of photons, and at the same time, both atomic states, with definite probabilities, are present. we then d...

Wind induced ovalling vibrations have been reported to occur on several empty, flexible silo structures in group arrangement. The focus in this paper is on the numerical prediction of this phenomenon by simulating the wind flow around a single silo and taking into account the interaction of the wind flow with the structural response. The importance of the 3D turbulent wind flow and wake effects...

In this paper we consider a quintom model of dark energy with non-minimal coupling between scalar field and modified gravity which is known f(R) gravity. The Lagrangian for scalar field has been inspired by tachyonic Lagrangian in string theory. Then we obtain the equation of state (EoS), and the condition required for the model parameters when ω crosses over −1. This model shows that for havin...
