Applications of some recent techniques for the exact solutions of the small disturbance potential flow equation of nonequilibrium transonic gas dynamics
(2000)Using the isovector approach as developed in [1] and the direct method of Clarkson and Kruskal [2], we have obtained similarity and other reductions to ordinary differential equations and exact solutions of the small ... 
Axisymmetric flow near a rotating permeable bed
(1995)Steadystate boundary layer flow generated on a rotating fluidsaturated porous bed when a column of axisymmetric frictionless potential flow arriving from infinity impinges on it is studied numerically by employing an ... 
Block coded modulation using twolevel group codes over generalized quaternion groups
(1997)This paper deals with Euclidean space codes obtained from twolevel group codes of length n over a generalized quaternion group Q m, m⩾3, with 2m elements, with generators x and y, given by the presentation ... 
Blockcoded modulation using twolevel group codes over generalized quaternion groups
(1999)A length n group code over a group G is a subgroup of Gn under componentwise group operation. Twolevel group codes over the class of generalized quaternion groups, Q(2m), m⩾3, are constructed using a binary code and ... 
Buoyancyinduced flow of nonnewtonian fluids in a porous medium past a vertical flat plate with nonuniform surface heat flux
(1994)Steady buoyancyinduced flow of a nonNewtonian fluid in a porous medium bounded by a vertical flat plate with prescribed variable wall heat flux is investigated analytically by KarmanPohlhausen integral method and ... 
Casson fluid flow in a pipe filled with a homogeneous porous medium
(1996)The flow characteristics of a Casson fluid in a tube filled with a homogeneous porous medium is investigated by employing the Brinkman model to account for the Darcy resistance offered by the porous medium. This analysis ... 
Categorization of image databases for efficient retrieval using robust mixture decomposition
(2001)In this paper, we present a robust mixture decomposition technique that automatically finds a compact representation of the data in terms of components. We apply it to the problem of organizing databases for efficient ... 
A computational method for regularized long wave equation
(2000)Quintic spline technique and splitting method have been used to develop a newfinite difference method to solve regularized long wave (RLW) equation. The convergence and the stability of the proposed method are discussed. ... 
Continuous interval in the dispersion spectrum
(2000)A measure for the denseness of sequences [an mod 1], a irrational, is the disper sion constant D(a) introduced by H. Niederreiter, [1981, Colloq. Number Theory 185, 4350]. In this paper a real number c has been found ... 
Convective heat transfer across a horizontal impermeable partition
(1994)The aim of this paper is to study the natural convection flow on both sides of an impermeable horizontal partition separating two semiinfinite fluid saturated porous reservoirs maintained at different temperatures. As a ... 
Correction to flow rate – pressure drop relation in coronary angioplasty: steady streaming effect
(1998)The changed flow pattern of pulsatile blood flow in a catheterized stenosed artery has been studied through a mathematical model. The study takes into account the effect the movement of the flexible catheter influenced by ... 
CS matrix rings over local rings
(2003)Complete characterization of CS matrix rings Mn(R), n>1, over local rings R is obtained. Application to group algebras is derived as a particular case of the main result. 
Duality in linear programming with fuzzy parameters and matrix games with fuzzy payoffs
(2003)A dual for linear programming problems with fuzzy parameters is introduced and it is shown that a two person zero sum matrix game with fuzzy payoffs is equivalent to a primal–dual pair of such fuzzy linear programming ... 
Dynamic interaction between boundary layer flow and groundwater flow separated by a porous bed
(1994)This paper examines the problem of dynamic interaction between a steadystate axisymmetric boundary layer flow over a fluidsaturated porous bed and a uniform Darcy flow occurring in the bed. The analysis is based on the ... 
EEstimation of increased flow resistance in a narrow catheterized artery — A theoretical model
(1996)The changed flow pattern in a narrow atheterized artery is studied and an estimate of the increased flow resistance is made. The anomalous behaviour of blood in small blood vessels has been taken into account by modelling ... 
Effect of secondary flows on contaminant dispersion with weak boundary absorption
(1997)The present anulysis brings out the interaction of curcature and a weak wall absorption parameter on the dispersion process using Taylor analysis. A perturbation series solution has been obtained to find the values of the ... 
A feature selection technique for classificatory analysis
(2005)Patterns summarizing mutual associations between class decisions and attribute values in a preclassified database, provide insight into the significance of attributes and also useful classificatory knowledge. In this paper ... 
Finite population cellular radio systems with directed retry
(1999)This paper proposes an analytically tractable model to predict the performance of cellular communication nonhomogeneous traffic originated from finite population in cellular radio system. In many locations in cellular radio ... 
Flow in a catheterized curved artery with stenosis
(1999)The fluid mechanics of blood flow in a catheterized curved artery with stenosis is studied through a mathematical analysis. Blood modelled as an incompressible Newtonian fluid and the flow is assumed to be steady and ...
