This study aimed at linear stability analysis of the stratified two-phase liquid-gas flow in a horizontal pipe. First, equations governing the linear stability of flow in each phase and boundary conditions were obtained. The governing equations were eigenvalue Orr Sommerfeld equations which are difficult and stiff problems to solve. After obtaining the velocity profiles of the gas and liquid ph...

A detailed analytic study of the log-linear phase transition of the Smith-Waterman local alignment algorithm is presented. A rectangular alignment lattice is introduced to facilitate the statistical analysis for alignment with gaps. With a few simplifying assumptions, we obtain an analytic expression for the loci of the phase transition line. Our result reproduces the exact and conjectured valu...

This paper presents a novel technique for designing an Infinite Impulse Response (IIR) Filter with Linear Phase Response. The design of IIR filter is always a challenging task due to the reason that a Linear Phase Response is not realizable in this kind. The conventional techniques involve large number of samples and higher order filter for better approximation resulting in complex hardware for...

In this paper a novel hybrid algorithm for harmonics estimation in power systems is proposed. The estimation of the harmonic components is a nonlinear problem due to the nonlinearity of phase of sinusoids in distorted waveforms. Most researchers implemented nonlinear methods to extract the harmonic parameters. However, nonlinear methods for amplitude estimation increase time of convergence. Hen...

in this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave rof) system that uses a dual drive mach zehnder modulator (dd-mzm), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. the input to the dd-mzm are binary phase shift keying (bpsk), quadrature phase shift keying (qpsk), 8-phase shift keying (8-psk) and...
