Semigroup presentation for congruences on groups
(KOREAN MATHEMATICAL SOC, 2013)
We consider a congruence rho on a group G as a subsemigroup of the direct product G x G. It is well known that a relation rho on G is a congruence if and only if there exists a normal subgroup N of G such that rho = {(s, ...
A Spectral solenoidal-galerkin method for rotating thermal convection between rigid plates
(HINDAWI LTD, 2013)
The problem of thermal convection between rotating rigid plates under the influence of gravity is treated numerically. The approach uses solenoidal basis functions and their duals which are divergence free. The representation ...
Electrocatalytic oxidation of methanol on Ru deposited NiZn catalystat graphite in alkaline medium
(ELSEVİER, 2013)
The methanol oxidation on C/NiZn-Ru electrode in a 1.00 M KOH and 1.00 M KOH + 1.00 M methanolsolutions at different scan rates and temperatures was studied by the cyclic voltammetry (CV), electro-chemical impedance ...
Global stability-based design optimization of truss structures using multiple objectives
(SPRINGER INDIA,, 2013)
This paper discusses the effect of global stability on the optimal size and shape of truss structures taking into account of a nonlinear critical load, truss weight and serviceability at the same time. The nonlinear critical ...
Entropy Generation for Nonisothermal Fluid Flow: Variable Thermal Conductivity and Viscosity Case
(HINDAWI PUBLISHING CORPORATION, 2013)
This paper investigates the entropy generation of a nonisothermal, incompressible Newtonian fluid flowing under the effect of a constant pressure gradient in plane Poiseuille flow. The effects of variable viscosity and ...
