When the times between renewals in a renewal process are not exponentially distributed, simulation can become a viable method of analysis. The renewal function is estimated through simulation for a renewal process simulation for a renewal process with gamma distributed renewal times and the shape parameter a > 1. Gamma random deviates will be generated by means of the so called Acceptance Rejec...

Wireless Sensor Networks (WSNs) have been an exciting topic in recent years. The services offered by a WSN can be classified into three major categories: monitoring, alerting, and information on demand. WSNs have been used for a variety of applications related to the environment (agriculture, water and forest fire detection), the military, buildings, health (elderly people and home monitoring),...

monte carlo simulation is widely used in calculations involing transport of photons through different materials of different shapes. the method consists of randomly generating a finite set of photon histories over which the quantities of interest are averaged. in photon transport calculations, sampling the photon scattering angle from the klein-nishina probability distribution is of special imp...

Multiphysics simulation refers to the inclusion of multiple physical phenomena in a single computational model. This may or may not require multiple solvers. For example, a mechanical solver could be used to model stent deployment to a vessel wall, and then either a mechanical or computational fluid dynamics (CFD) solver could be used to model drug diffusion in the vessel tissue. In situations ...

A parallel implementation of the numerical simulation of a GaAs MESFET device using the finite difference discretisation scheme and solved by a point iterative method is presented. Parallel techniques targeted at Multiple-Instructions Multiple-Data (MIMD) message-passing distributed memory architectures, in particular, Transputers, are described. Efficient parallelism is achieved by the geometr...

Registering 3D point sets subject to rigid body motion is a common problem in computer vision. The optimal transformation is usually specified to be the minimum of a weighted least squares cost. The case of 2 point sets has been solved by several authors using analytic methods such as SVD. In this paper we present a numerical method for solving the problem when there are more than 2 point sets....

Separation of a racemic mixture of ibuprofen at a low concentration level by supercritical fluid chromatography in a simulated moving bed (SFC-SMB) is investigated by simulation. The feasibility of ibuprofen enantiomers separation has been experimentally examined in the literature. Our simulation results show that separation of ibuprofen enantiomers is feasible by this method, and R-ibuprofen a...

This paper proposes a sensor placement method for three-dimensional point source localization using multiple sensors. An observation model of multiple sensors and one source of unknown position is introduced. Given that model, the minimum number of sensors needed to localize the source is determined, and an optimal sensor placement is derived. The placement is optimal in the sense that it minim...

A computer simulation model may be regarded as a mapping function bietween a set of input and output variables. Although simulation models are very popular experimentation tools, in many cases they are computationally expensive. Hence, it would be essential to have fast, accurate approximation of computer simulation. This paper examines the use of an evolutionary artificial neural network for a...
