Abstract: We are proposing a new network transmission model wherein we have a number of users who wish to send their throughput demand in the form of packets through one or more links with minimum cost or more efficiently than the other users. This situation introduces the role of non-cooperative games in the communication network. We introduce three aspects which distinguish this model from other transmission network models studied elsewhere. These aspects are regarding introduction of time (discrete) and penalty to the users, and cost of transmission to be an increasing function of time.
Keywords: Convex, Nash equilibrium, Non-cooperative game

Abstract:In this paper, we have investigated Bianchi Type I spacetime filled with viscous fluid in the presence of magnetic field. Here we assume an equation of state p  . We obtain the solution according to the law, the variation of the average Hubble parameter given by Berman: n H Da  . The geometrical and kinematical features of the model are also discussed.

Abstract: The paper investigated the radiation and chemical reaction effects of mass transfer and Hall current on unsteady MHD flow of a viscoelastic fluid in a porous medium. The resultant equations have been solved analytically. The velocity, temperature and concentration distributions are derived, and their profiles for various physical parameters are shown through graphs. The coefficient of Skin friction, Nusselt number and Sherwood number at the plate are derived and their numerical values for various physical parameters are presented through graphs. The influence of various parameters such as the thermal Grashof number, mass Grashof number, Schmidt number, Prandtl number, viscoelasticity parameter, Hartmann number, Hall parameter, and the frequency of oscillation on the flow field are discussed qualitatively.
Keywords:Chemical reaction, MHD,Nusselt number, thermal Grashof number, viscoelasticity parameter.
