Finite difference solution othird order viscous wave equation
(International journal of engineering, science and mathematics, 2014)
A new numerical method for Nwogu’s (ASCE Journal of Waterway, Port, Coastal and Ocean En-gineering1993;119:618) two-dimensional extended Boussinesq equations is presented using a lineartriangular nite element spatial ...
A HIV/AIDS model in a homogeneous population with time lags in the transmission
(HIKARI Ltd: Applied Mathematical Sciences, 2014-01-01)
We investigate a simple HIV/AIDS epidemic model in a heterosexual population by by modifying a Susceptible-Infective-Removed (SIR) model. The model considers sexual transmission of HIV where individuals are being recruited ...
Some Irreducible 2-Modular Codes invariant Under The Symplectic Group S6(2)
(GLASNIK MATEMATIˇ CKI, 2014-01-01)
We examine all non-trivial binary codes and designs obtained from the 2-modular primitive permutation representations of degrees up to 135 of the simple projective special symplectic group S6(2). The submodule lattice of ...
Distribution of spectrum in a direct sum decomposition of operators into normal and completely non-normal parts
(Modern Scientific press : IJMMS, 2014-01-01)
We discuss the distribution of spectra of a direct sum decomposition of an arbitrary operator into normal and completely non normal parts. We utilize the fact that any given operator 𝑇∈𝐵(𝐻) can be decomposed into a ...
A Predator-Prey Model with a Time Lag in the Migration
(2014)
We develop a two-patch migration model of the classical LotkaVoltera predator-prey system with a time lag in the migration between
patches. We show that when the migration rate is less than the prey
growth rate the species ...
