Uptake of sodium chloride by mixture of weakly acidic and weakly basic ion exchange resins: equilibrium and kinetic studies
(2004)The equilibrium and kinetic behaviour of weakly acidic resin (WAR) with alkali and weakly basic resin (WBR) with acids have been studied by many research teams. But little work is reported in literature regarding equilibrium ... -
Use of an updated finite element model for dynamic design
(2002)Model updating techniques are used to update a finite element model of a structure so that an updated model predicts more accurately the dynamics of a structure. The application of such an updated model in dynamic design ... -
User feedback based enhancement in web search quality
(2004)Of late, there has been a paradigm shift in web searching from the content based searching to the connectivity based or more commonly known as hyperlink based (or simply link based) searching. But, both the content based ... -
Using renewable energy technologies for domestic cooking in India: a methodology for potential estimation
(2002)An attempt has been made to estimate the potential of using biogas plants, solar cookers and improved cookstoves for domestic cooking in India. Based on 1991 statistics on the bovine population and ownership pattern, the ... -
Utilisation of agro-residues as animal feed through bioconversion
(1997)Bioconversion of agro-residues, rice straw and wheat straw, was carried out with the edible mushroom Pleurotus sajor-caju, with a view to increasing nutri-tive values and digestibilities for animal feed. Amongst the inorganic ... -
Utilisation of fruits waste for citric acid production by solid state fermentation
(2003)A solid state fermentation method was used to utilise pineapple, mixed fruit and maosmi waste as substrates for citric acid production using Aspergillus niger DS 1. Experiments were carried out in the presence and absence ... -
Utilization potential of solar energy in the Indian silk industry
(1994)A case is made for the use of solar energy in meeting the energy requirements of the silk production and processing industry of India. The paper briefly reviews the energy requirements of the silk industry and identifies ... -
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 3-phase 4-wire 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 three-phase ... -
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 multi-input multi-output 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 code-excited linear predictive (CELP) speech coder using the average error in reconstruction of the excitation signal as the distortion measure and use ... -
Velocity measurement in solid-liquid 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 ... -
