The Wigner quasi-probability distribution function is a familiar tool to many working in quantum and atom optics [1]. It is primarily used in the classical-quantum correspondence where the appearance of positive and negative regions of the Wigner function gives easily understood information concerning the probability concentrations and quantum interferences present within the quantum state [2]....

We present an optimized algorithm to estimate from shifted stellar spectra the variations of radial velocity caused by a rotating planet. This algorithm is based on a rigorous approach in the spectral Fourier space that uses a weighted analysis of the cross spectrum phase between the high resolution spectra of the object and an appropriate reference. We give a simple method to calculate the bes...

Introduction: The main goal of SPECT imaging is to determine activity distribution inside the organs of the body. However, due to photon attenuation, it is almost impossible to do a quantitative study. In this paper, we suggest a mathematical relationship between activity distribution and its corresponding projections using a transfer matrix. Monte Carlo simulation was used to find a precise tr...

the dependence of the lateral distribution of cherenkov light in simulated extensive air showers to the energy and the mass of the primary cosmic rays has been studied. it has been shown that a previous claim about mass independent proportionality of shower energy to the total cherenkov photon number is not valid in energies below eeas ~ 1014 ev. we have found that the core distance of the so c...

Dust particles charging in a stratified positive column of a low-pressure DC glow discharge was investigated theoretically. The presented model consists of (i) previously developed 1D selfconsistent model for discharge parameters on the tube axis; (ii) ambipolar approximation for radial electric potential distribution and the assumption that the electron energy distribution function in radial d...

A theoretically based closed-form analytical equation for the radial distribution function, g(r), of a fluid of hard spheres is presented and used to obtain an accurate analytic representation. The method makes use of an analytic expression for the short- and long-range behaviors of g(r), both obtained from the Percus-Yevick equation, in combination with the thermodynamic consistency constraint...

Distribution feeder reconfiguration has been an active field of research for many years. Some recent theoretical studies have highlighted the importance of smart reconfiguration for the operating conditions of such radial networks. In general, this problem has been tackled using a multi-objective formulation with simplified assumptions, in which the uncertainties related to network components h...

A Radial Distribution network is important in power system area because of its simple design and reduced cost. Impact of Distributed generation in radial distribution feeder is increased because of its application of green technology and it also meet out some of the power system issues. Allocation of Distributed Generation at non-optimal places leads to increased power loss and reduced bus volt...

in this article, a multi-objective function for placement of distributed generation (dg) and capacitors with thetap setting of under load tap changer (ultc) transformer is introduced. most of the recent articles have paidless attention to dg, capacitor placement and ultc effects in the distribution network simultaneously. insimulations, a comparison between different modes was carried out with,...
