A joint performance measure for the decorrelating multiuser detector
(2004)We analyze the performance of the decorrelating multiuser detector for a wireless communication system. Instead of looking at the error probability for each user, we focus on the probability distribution of the number of ... -
Kadomtsev-Petviashvili solitons in inhomogeneous plasmas with finite temperature drifting ions
(1994)Two-dimensional ion acoustic solitons travelling in a spatially inhomogeneous plasma with finite temperature drifting ions are studied. The modified Kadomtsev-Petviashvili (mKP) equation governing the soliton propagation ... -
The kenics static mixer: new data and proposed correlations
(1995)New results forwall-to-tube heat and mass tranfer in a kenics-type static mixer allow a unification of extent data. Nearly universal correlations are presented. They allow detailed comparision with open tube designs. heat ... -
Kinetic model of ATP synthase: pH dependence of the rate of ATP synthesis
(2000)Abstract Recently, a novel molecular mechanism of torque generation in the F0 portion of ATP synthase was proposed [Rohatgi, Saha and Nath (1998) Curr. Sci. 75, 716-718].In this mechanism, rotation of the c-subunit was ... -
Kinetic modeling of ATP synthesis by ATP synthase and Its mechanistic implications
(2000)Based on the torsional mechanism of ATP synthesis by ATP synthase, a kinetic scheme has been developed in this work. The scheme considers adenine nucleotide transport, binding of substrates ADP and Pi, unbinding of product ... -
Kinetic studies and shrinking core model on solvolytic extraction of coal
(2000)The studies on the kinetics of solvent extraction of coal using N-methyl 2- yrrolidone NMP, anthracene oil, and cetene have been performed separately. The extractionsrreactions were found to have first order rate law. The ... -
Kinetic theory of ion-cyclotron wave using energy conserving BGK collision operator
(1989)The kinetic ion-cyclotron instability in the presence of an external DC drift has been investigated. The electron-ion collisions were assumed to be the dominant collisions. The energy-conserving BGK collision operator was ... -
Kinetics of adsorption on biporous solids—for a system with rectangular equilibrium—reanalysed
(1994)Mass transfer equations describing the rate of adsorption for rectangular equilibrium on biporous solids were solved numerically by finite difference technique. Values of parameters affecting the rate of adsorption were ... -
Kinetics of biosorption of cadmium on Baker’s yeast
(2003)In the present study the kinetics of biosorption of cadmium(II) ions by deactivated protonated yeast converted to sodium form was investigated for different initial concentrations of the metal ion (10–100 ppm) and different ... -
Kinetics of pyrolysis of rice husk
(1999)The pyrolysis of rice husk in both grain and powder form was investigated to determine the kinetic parameters. Experiments under non-isothermal conditions were carried out for rice husk grain and powder samples in nitrogen, ... -
Kinetics of rice husk char gasification
(2001)The gasification of rice husk char in carbon dioxide and steam was investigated for determining the kinetic parameters. Experiments were conducted with rice husk char in its original grain form in a silica tube reactor ... -
Kosterlitz-Thouless transition and fluctuation effects in YBa2Cu3O7−x thin films
(1994)Fluctuation effects and temperature dependance of IV characteristics of c-axis oriented YBCO thin films on STO(100) have been investigated within the context of unbinding of vortex-antivortex pairs in the Kosterlitz-Thouless ... -
(La0.4Ba0.4Ca0.2)(Mn0.4Ti0.6)O3: A new titano-manganate with a high dielectric constant and antiferromagnetic interactions
(2004)A new perovskite-based titano-manganate, (La0.4Ba0.4Ca0.2)(Mn0.4Ti0.6)O3, has been prepared by the ceramic route at 1100°C. This oxide was found to possess the cubic perovskite structure with ‘a’=3.9477(23) Å (space group ... -
Lactose hydrolysis by Lactozym™ immobilized on cellulose beads in batch and fluidized bed modes
(2003)Lactozym™ is a commercially available preparation of β-galactosidase from Kluyveromyces fragilis. It has valid generally recognized as safe (GRAS) status for whey hydrolysis and production of low lactose milk. Immobilized ... -
Laminar convection of non-Newtonian fluids in the thermal entrance region of coiled circular tubes
