Oscillation of a Third Order Nonhomogeneous Differential Equation.
This thesis considers the third order, nonhomogeneous, (NH), linear differential equation(NH) y'"+ p(x)y' + q(x)y = f(x),together with the associated homogeneous equation(H) u'" + p(x)u' + q(x)u = 0.The coefficient functions p(x), q(x), and the forcing function f(x) are assumed to be continuous, …

On the Oscillation of a Fourth Order Nonhomogeneous Differential Equation.
The primary concern of this study is the oscillation of solutions of (NH). Oscillation of fourth order homogeneous equations has been studied by M. S. Keener, and W. Leighton and Z. Nehari.

Nonhomogeneous Initial Boundary Value Problems for Two-Dimensional Nonlinear Schrodinger Equations
… and on a strip domain R x [0,L] with Dirichlet nonhomogeneous boundary data in a two-dimensional plane. Compared with pure initial value problems (IVPs), IBVPs over part of entire space with boundaries are more applicable to the reality and can provide more accurate data to physical experiments …

Effects of nonhomogeneous cementation in soils on resistance to earthquake effects
… of the stronger mass. The cyclic strength of the nonhomogeneous material, however, is higher than the independent strength of the weak lens. A weak lens has greater influence at relatively higher levels of cyclic stress. Pore pressure generation in cemented sands are seen to be controlled by …

Modeling repairable system failure data using NHPP reliability growth mode.
… the behaviour of repairable systems. The Crow nonhomogeneous Poisson process (NHPP) often known as the Power Law model is regarded as one of the best models for repairable systems. The goodness-of-fit test rejects the intensity function of the power law model, and so the log-linear model was …

Digital Simulation of Compaction in Sedimentary Sequences
… fluid in generating the excess pore pressure in nonhomogeneous sedimentary sequences is developed. In this model, physical properties of fluid and sediments are considered to vary with temperature and pressure. The Crank-Nicolson finite difference method is used to solve the partial differential …
