On the numerical modelling of a dc driven glow discharge plasma
Rafatov, İsmail; Kudryavtsev, Aa (2012-09-01)
We developed and tested two dimensional (axial-symmetric) models of a dc glow discharge in low pressure argon gas using two approaches. First, assembling the model from the ”general form” COMSOL Multiphysics pde’s, and second, using COMSOL’s built-in ”Plasma Module”. Calculation results have been compared with those obtained from the CFD-ACE+ package. The discharge models are based on a fluid description of ions and excited neutral species with drift-diffusion approximation for the particle flux. The data f...
On the Design and Implementation of Higher Order Differential Microphones
De Sena, Enzo; Hacıhabiboğlu, Hüseyin; Cvetkovic, Zoran (2012-01-01)
A novel systematic approach to the design of directivity patterns of higher order differential microphones is proposed. The directivity patterns are obtained by optimizing a cost function which is a convex combination of a front-back energy ratio and uniformity within a frontal sector of interest. Most of the standard directivity patterns-omnidirectional, cardioid, subcardioid, hypercardioid, supercardioid-are particular solutions of this optimization problem with specific values of two free parameters: the...
On the assessment of the effect of the anisotropy in in-situ stress on support pressure in tunnels
Osgoui, Reza. R. (2006-06-21)
This paper presents a newly empirical approach to estimate support pressure in rock tunnels. The new approach takes the rock mass quality (Geological Strength Index: GSI), the disturbance degree, the post-failure behavior, the size of tunnel, the state of in-situ stresses, and the squeezing-prone condition into consideration. A parametric study was, too, carried out using numerical analysis to investigate the influence of anisotropy in field stresses and the effect of the various shapes and sizes of tunnels...
On the Implementation of Optimal Receivers for LFM Signals using Fractional Fourier Transform
Candan, Çağatay (2008-05-30)
We present a novel receiver structure for the detection and parameter estimation of linear frequency modulated signals. The proposed structure is based on the relations between the fractional Fourier transform and the ambiguity function. It has been shown that the optimal ML receiver, which is the peak detector in the ambiguity plane, can be implemented at a reduced search complexity with the proposed method. The proposed method uses two 1-dimensional search operations in two different fractional Fourier do...
