uOxobridged heterotrinuclear compounds containing antimony(V) and arsenic(III). Crystal structures of Ar3Sb(uOAsPh2)2 (Ar=Ph or ptol)
(1999)Novel compounds containing open chain Sb(OAs)2 units have been synthesised by reacting Ar3SbBr2 (ArPh or ptol) with Ph2AsLi in dry THF:benzene under a N2 atmosphere, followed by a work up of the reaction mixture under ... 
An uncalibrated lightfield acquisition system
(2004)Acquisition of image data for lightfield usually requires an expensive, complex and bulky setup. In this paper, we describe a simple method of acquiring the image data set. The method requires a normal handheld video camera, ... 
Uniqueness of solutions of networks with two terminal piecewise linear resistors
(1994)For networks containing resistors, independentsources, gyrators, ideal transformers, diodes and other saturating monotone piecewise linear resistors, a new condition is proposed to guarantee uniqueness of solutions. This ... 
Unity power factor converterinverter fed vector controlled cage motor drive without mechanical speed sensor
(1995)This paper presents a comprehensive analysis of a vector controlled induction motor drive. The motor is fed from a current controlled converterinverter system which acts as an ideal frequency changer and offers four ... 
A universal active power filter for singlephase reactive power and harmonic compensation
(1998)In modern power distribution systems, the majority of loads draw reactive power and/or harmonic currents from the AC source along with main active power currents. These nonunity power factor linear and nonlinear loads cause ... 
Updated mathematical model and fedbatch strategies for polyBhydroxybutyrate (PHB) production by alcaligenes eutrophus
(1998)The growth and the intracellular biopolymer PolyB Hydroxybutyrate (PHB) storage kinetics of Alcaligenes eutrophus were studied in a batch cultivation process.N/C ratio was found to both limit and inhibit the growth of the ... 
Upper hybrid wave pumped free electron laser
(1995)A large amplitude upper hybrid wave has potential to be employed as a wiggler for the generation of high frequency coherent radiation via free electron laser (EEL) instability. At a density fluctuation level of a few ... 
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 agroresidues as animal feed through bioconversion
(1997)Bioconversion of agroresidues, rice straw and wheat straw, was carried out with the edible mushroom Pleurotus sajorcaju, with a view to increasing nutritive 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 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 ...
