Mobile IP is the Internet Engineering Task Force (IETF) proposal to cater for All-Internet Protocol (All-IP) mobility. It forms the backbone for next generation Wireless Internet Technology to provide uninterrupted network service while on the move. Our paper conducts a performance study of the various Mobile Internet Protocol version 6 (IPv6) protocols(More)
The design and development of a real-time enhanced password security system, based on the analysis of habitual typing rhythms of individuals, is discussed in this paper. The paper examines the use of force exerted on the keyboard and time latency between keystrokes to create typing patterns for individual users. Pressure signals which are taken from the(More)
Pulsed air jet impingement system is one of the most important area of heat transfer studies due to its wide engineering applications in heating and cooling such as in textile drying and electronics cooling. In this paper, the tests parameters used are a constant Reynolds number of 16000, Copper impingement plate surface temperature of 100°C, radial(More)
Pulsed air jet is a very interesting new research area due to its contribution towards heat and mass transfer enhancement and has a potential for future industrial application. It has been proven that pulsed air jet has better heat transfer performance compared with steady air jet system for certain flow geometry under certain conditions only. The objective(More)
—In this paper, the homotopy-perturbation method (HPM) is employed to obtain approximate analytical solution to the linear and nonlinear systems of partial differential equations (PDEs). HPM yields solutions in convergent series forms with easily computable terms. Generally, the closed form of the exact solution or its expansion is obtained without any(More)
In this paper, a gas kinetic solver is developed for the Reynolds Average Navier-Stokes (RANS) equations in two-space dimensions. To our best knowledge, this is the first attempt to extend the application of the BGK (Bhatnagaar-Gross-Krook) scheme to solve RANS equations with a turbulence model using finite difference method. The convection flux terms which(More)
