An (m, M) machine repair problem with spares and state dependent rates: A diffusion process approach
(1997)The diffusion approximation model for (m, M) general machine repair problems with spare part support has been developed. The inter-failure time and repair times are assumed to be generally identically and independently ... -
Macroaffinity ligand-facilitated three-phase partitioning for purification of glucoamylase and pullulanase using alginate
(2003)Starch-degrading enzymes glucoamylase (from Aspergillus niger), and pullulanase (from Bacillus acidopullulyticus) were purified using alginates (polysaccharides consisting of mannuronic acids and guluronic acids) by a ... -
Macromolecular investigations by laser light scattering
(1995)In a liquid suspension the small particles dance around randomly executing Brownian motion. When laser light is focussed onto such a solution, the total light scattered consists of a superposition of the light scattered ... -
Magnetic alginate microparticles for purification of α-amylases
(2003)Spherical magnetic alginate microparticles (25–60 μm in diameter) were prepared using the microemulsion system, with water-saturated 1-pentanol as the organic phase. The limited solubility of 1-pentanol in water enabled ... -
Magnetic properties of In3+ and Cr3+ substituted Mg–Mn ferrites
(2002)Two series of magnesium–manganese ferrites, viz., Mg0.9Mn0.1InxFe2−xO4 and Mg0.9Mn0.1CryFe2−yO4 have been prepared using conventional ceramic technique. Magnetic properties such as saturation magnetization (Ms), Curie ... -
Magnetic properties of nickel-zinc ferrites prepared by the citrate precursor method
(2000)Magnetic properties such as Curie temperature, saturation magnetisation, hysteresis loop and permeability loss factor of various compositions of NiZn ferrites prepared by the non-conventional citrate precursor method are ... -
Magnetoresistive behaviour of La0.67(Ca0.33-xpbx) MnO3 nanopowders prepared at lower temperature
(2001)We have been able to prepare ultrafine powders of pure and doped La Ca MnO (LCMO) at a relatively lower temperature of 5508C using a simple, cost effective and versatile PVA-based chemical route. A maximum magnetoresistance ... -
Maintainability design and evaluation of mechanical systems based on tribology
(2002)Maintainability of mechanical systems based on tribology is suggested and evaluated in this paper. Tribo-features of mechanical systems, which characterise maintainability are identified and are modelled in terms of ... -
Managing document images in a digital library: an ontology guided approach
(2004)We present Heritage+, an integrated platform for interactive access of different types of media elements through an unified interface. A unique aspect of Heritage+ is that it deals with document images as distinct media ... -
Market constrained optimal planning for wind energy conversion systems over multiple installation sites
(2002)This paper presents two market dependent optimization algorithms that can be used to plann wind energy conversion system (WECS)installations simultaneously over several sites of interest to a utility, ithin the scope of ... -
Mass transfer limitations in a membrane module
(1993)Application of reverse osmosis in the manufacture of sugar from cane juice and beet juice is emerging as a major potential field for energy conservation. The effect of flow velocity and pressure of operation is closely ... -
Mass transfer with instantaneous chemical reaction in finite gas–liquid systems
(2000)The moving-boundary problem of gas absorption accompanied by an instantaneous irreversible chemical reaction in a limited gas–liquid system has been analyzed. Analytical solutions have been derived, under the restrictions ... -
Mass-transfer studies of solvent extraction of coals in N-methyl-2-pyrrolidone
(2000)Mass-transfer plays an important role in the solvent extraction of coals. The studies on the kinetics of diffusion of the solvent in coals help in understanding the process of mass-transfer in coal. The coal molecules get ... -
Matching characteristics of the physically short linear impedance transformer
(2001)In contrast to the conventional quarter-wavelength transformer for matching two transmission lines of different characteristic impedance, it has been found that the length can be significantly shortened by using two ... -
Matching of technological forecasting technique to a technology
(2002)Technological forecasting (TF) has been acknowledged as an effective tool in setting technology strategies. A large number of techniques have been evolved for TF. The quality of forecasts would greatly depend on proper ... -
Matching structural shape descriptions using genetic algorithms
(1997)This paper presents a genetic algorithm for solving the problem of structural shape matching. Both sequential and parallel versions of the algorithm have been presented. The genetic operators-- reproduction,crossover and ... -
Mathematical model for atmospheric dispersion in low winds with eddy diffusivities as linear functions of downwind distence
(Elsevier Sclerce, 1996)The dispersion modelling in tow wind speeds assumes importance because of the high frequency of occurrence and episodic nature of these poor diffusion conditions. A steady-state athematical model has been proposed for the ... -
A mathematical model for the dispersion of air pollutant in low wind condition
(Elsevier Science, 1996)For the atmospheric dispersion of pollutants in low wind conditions, a steady-state mathemat- ical model has been formulated which takes into account the diffusion in all the coordinate directions and the advection due to ... -
Mathematical modeling for greenhouse heating by using thermal curtain and geothermal energy
(2004)A thermal model has been developed for the heating of a greenhouse by using inner thermal curtain and natural flow of geothermal warm water through the polyethylene tube laid on its floor. The calculations were done for a ... -
