Variable mesh difference schemes for solving a nonlinear schrodinger equation with a linear damping term
(2000)This paper describes moving variable mesh finite difference schemes to numerically solve the nonlinear Schrodinger equation including the effects of damping and nonhomogeneity in the propagation media. These schemes have ... 
Variable structure control of four pole voltage source inverter for active filtering of nonlinear loads in 3phase 4wire systems
(1998)This paper presents the analysis of four leg voltage source inverter (VSI) used as an active filter (AF) for reactive power compensation, load balancing, harmonic elimination and neutral current compensation in threephase ... 
A variant of time minimizing assignment problem
(1998)A time minimizing assignment problem (TMAP) dealing with the allocation ofn jobs to m(< n) persons is considered in this paper. One job is to be allocated to exactly one person and each person does at least one job. All ... 
Various methods of emission estimation of vehicular traffic in delhi
(1998)Traffic is the predominant source of pollution in urban cities like Delhi. Continuous monitoring of the air quality in roads will be very costly and impracticable. To carry out model calculations is a useful alternative ... 
Vector modes of an optical fiber in the weakly guiding approximation
(1989)The authors show that starting from the appropriate linear combinations of LP modes, the weakly guiding approximation of the hybrid modes can be easily obtained without any reference to the rigorous vector modes. The ... 
Vector multirate filtering and matrix filter banks
(1992)Multichannel or multiinput multioutput multirate filtering is discussed. Vector multirate systems are defined, and the issues of aliasing cancellation and perfect reconstruction are addressed in the vector context. The ... 
Vector quantization of excitation gains in speech coding
(2000)In this paper, we consider vector quantization of excitation gains in codeexcited linear predictive (CELP) speech coder using the average error in reconstruction of the excitation signal as the distortion measure and use ... 
Velocity measurement in solidliquid flows using an impact probe
(1997)The use of a modified impact tipe of probe for velocity field measurent in the flow of multysized(dso=71pm)parteculate slurries is discribed.The impact probe has a sensor similar to a two hole offset probe but has a modified ...

Vibration control in machines and structures using viscoelastic damping
(1998)The work on vibration control of machines and structures incorporating viscoelastic materials in suitable arrangements is highlighted for situations involving vibration excitations over a broad frequency range.The principle ... 
Vibration of continuous bridges under moving vehicles
(1994)The dynamic behaviour of multispan continuous bridges under a moving vehicular load is investigated by considering the effect of interaction between the vehicle and the bridge pavement, the torsion in the bridge due to ... 
Video shot interpretation using principles of perceptual prominence and perceptual grouping in spatiotemporal domain
(2004)We propose a computational model for generating an interpretation of a video shot based on our proposed principle of perceptual prominence. We also provide a formulation of the perceptual grouping problem in the spatiotemporal ... 
Virtual partition algorithm in a nested transaction environment and its correctness
(2001)In this paper, we present a formal description of the virtual partition algorithm in a nested transaction environment and prove its correctness. We model the virtual partition algorithm in a nested transaction environment ... 
A visible plasma
(1989)Summary form only. The authors have obtained a steadystate plasma with the plasma frequency in the visible. Thus, in principle, phenomena such as the production of electron plasma oscillations can be observed visually. ...
