S U M M A R Y We propose a forward wavefield simulation based on a particle continuum model to simulate seismic waves travelling through a complex subsurface structure with arbitrary topography. The inclusion of arbitrary topography in the numerical simulation is a key issue not only for scientific interests but also for disaster prediction and mitigation purposes. In this study, a Hamiltonian ...

In this paper, He’s homotopy perturbation method (HPM) is applied to spatial one and three spatial dimensional inhomogeneous wave equation Cauchy problems for obtaining exact solutions. HPM is used for analytic handling of these equations. The results reveal that the HPM is a very effective, convenient and quite accurate to such types of partial differential equations (PDEs). Keywords—Homotopy ...

We introduce two powerful methods to solve the Davey-Stewartson equations: one is the homotopy perturbation method (HPM) and the other is the homotopy analysis method (HAM). HAM is a strong and easy to use analytic tool for nonlinear problems. Comparison of the HPM results with the HAM results, and compute the absolute errors between the exact solutions of the DS equations with the HPM solution...

Abstract. One of the newest analytical methods to solve nonlinear dispersive wave equations is using both homotopy and perturbation methods which is called (HPM). Other the reliable methods are variational iteration method (VIM) by He and Adomian's decomposition method (ADM). Here, we compare the exact solution of HPM which are applied to solve a various fifth-order Korteweg-de Vries problems w...

The Homotopy Perturbation Method (HPM) is used to solve the Burgers-Huxley non-linear differential equations. Three case study problems of Burgers-Huxley are solved using the HPM and the exact solutions are obtained. The rapid convergence towards the exact solutions of HPM is numerically shown. Results show that the HPM is efficient method with acceptable accuracy to solve the Burgers-Huxley eq...

The present study aimed to compare microbead injection with and without hydroxypropyl methylcellulose (HPM) in order to establish an experimental animal model of glaucoma. This model was established in C57BL/6 mice and transgenic mice expressing cyan fluorescent protein (CFP) under the control of the Thy1 promoter in retinal ganglion cells (RGCs). C57BL/6 mice aged between 12 and 20 weeks old w...

The suitability of various radiating systems for generating a directive high power microwave (HPhl ) beam is investigated. It is concluded that offset reflector antenna systems are well suited for this purpose. An HPM reflector antenna may consist of one or two reflectors that are illuminated by single or array feeds. To accurately predict the performance of an HPM reflector antenna, a versatil...

Title of Document: CHARACTERIZATION AND MODELING OF HIGH POWER MICROWAVE EFFECTS IN CMOS MICROELECTRONICS. Michael A. Holloway, Doctor of Philosophy, 2010 Directed By: Professor & Chair, Patrick G. O'Shea, Department of Electrical and Computer Engineering The intentional use of high power microwave (HPM) signals to disrupt microelectronic systems is a substantial threat to vital infrastructure....

Goat antibody IgG produced against bovine corpus luteum mitochondrial cytochrome P-450 (P-450scc) associated with cholesterol side chain cleavage (CSCC) was used to compare immunological characteristics of mitochondrial cytochrome P-450s from the bovine adrenal cortex (BAM), bovine corpus luteum (BCLM), and human placenta (HPM). In Ouchterlony double diffusion, anti-P450scc produced a single ba...

It is well known that Peer-to-Peer systems are generally featured with high flexibility and scalability, enabling dynamic resources localization and mutualization, and allowing the nodes to freely join and leave. But in some special environments such as mobile P2P networks, routing optimization, resources reliability and availability are critical concerns. To deal with these issues, we propose ...
