Energy distribution in a Schwarzschild-like spacetime
(2007)In this paper, utilizing Moller's energy-momentum complex, we explicitly evaluate the energy and momentum density associated with a metric describing a four-dimensional, Schwarzschild-like, spacetime derived from an effective ... -
Energy-Momentum Localization for a Space-Time Geometry Exterior to a Black Hole in the Brane World
(2013)In general relativity one of the most fundamental issues consists in defining a generally acceptable definition for the energy-momentum density. As a consequence, many coordinate-dependent definitions have been presented, ... -
Modelling the Environmental Effects of Railway Vibrations from Different Types of Rolling Stock: A Numerical Study
(2015)This paper analyses the influence of rolling stock dynamics on ground-borne vibration levels. Four vehicle types (Thalys, German ICE, Eurostar, and Belgian freight trains) are investigated using a multibody approach. First, ... -
Numerical modeling of pyrolytic laser-induced chemical vapor deposition
(2003)Laser chemical vapor deposition (LCVD) is a technique to deposit thin films of oxidation, corrosion, and wear resistant as well as electronic, optoelectronic, and superconductor materials. In order to understand the ... -
Variational analysis of gradient elastic flexural plates under static loading
(2010)Gradient elastic flexural Kirchhoff plates under static loading are considered. Their governing equation of equilibrium in terms of their lateral deflection is a sixth order partial differential equation instead of the ...
