Examination of a Semi-Analytic Finite Element for Plate Bending Problems
In this thesis the Semi-Analytic Finite Element Method of analysis of laterally loaded rectangular plates is examined. A computer program is described in which the eigenfunctions of free vibration of uniform beams are used as the analytic functions. Rectangular plates with any combination of simply …

Homotopy Analysis Method For Nonlinear Ordinary Eigenvalue Problems
… differential equations by the homotopy analysis method (HAM), which is a semi-analytic method first introduced by Shijun Liao in 1992. The modified HAM can be viewed as a more generalized method that encloses many perturbation and non-perturbation methods. It is different from perturbation or …

Analytical solutions of pressure-production tests with permanent multisensors in oil gas and water zones
… technologies for improving the monitoring methods for wells. These wells may have up to eight pressure sensors, recording infrastructure, and data transmission. The information from the sensors is at the disposal of the analyst immediately after the measurements are performed to make …

Numerical solution and spectrum of boundary-domain integral equations
… BDIE/BDIDE) are solved by the LU decomposition method and Neumann iterations. Convergence of the iterative method is analyzed in relation with the eigen-values of the corresponding discrete BDIE/BDIDE operators obtained numerically. The systems obtained from LBDIE/LBDIDE (discretised …

Solving variable coefficient partial differential equations using the boundary element method.
… coefficient PDEs using the boundary element method have been investigated. The application of the boundary element method to these equations is hampered by the difficulty of finding a fundamental solution. In the literature several methods have been proposed to overcome this problem. A survey …

Ultrafast Dynamics and Interactions During Growth at Surfaces
… which greatly exceeds that of alternative methods, makes it possible to probe motion on picosecond to nanosecond timescales. The present thesis is concerned with 3HeSE measurements and modelling of ultrafast dynamics in surface systems with interadsorbate interactions that induce the …
