Investigating spherical nano-particles by illumination of Gaussian beam was studied. In order to simulate the scattering e¤ect new software simulation based on the Bromwich formulation and the Mie theory was developed. The scattering simulation enables us to examine the scattered …eld a¤ected by the particle size and material composition. Studying the scattered …elds yielded sensors con…guratio...

1. The integration of different dynamic models, expressed in a variety of formalisms, avoiding the creation of dependency relations among them as much as possible. This is important to achieve modularity, allow flexible scenario composition, and facilitate reuse of simulation models. 2. The inclusion of dynamic models into a game architecture with minimum performance impact. 3. The communicatio...

The Anaerobic Digestion Model No. 1 (ADM1) was applied for the mathematical simulation of the thermophilic mono-fermentation of maize silage. Data from a period of 140 days of pilot plant operation were used for model calibration. The substrate characterization in terms of carbohydrates, proteins, lipids and inert matter was based on data derived from fodder analysis. The model was capable of a...

The amount of pollutant gases in the atmosphere has reached a critical state due to an increase in industrial development and the rapid growth of automobile industries that use fossil fuels. The combustion of fossil fuels produces harmful gases such as carbon dioxide, nitrogen monoxide (NO), soot, particulate matter (PM), etc. The use of Dimethyl Ether (DME) biofuel in diesel engines or other c...

This paper presents "Scythe and Sew", a software environment for analyzing lighting simulation data. It provides a spreadsheet like infrastructure for manipulating high-dimensional simulation results. It allows users to both import and create lighting simulation data, or patterns, into a workspace for inspection. A composition area allows the user to perform algebraic operations on the patterns...

Simulation of specifications is introduced as a unification and generalization of refinement mappings, history variables, forward simulations, prophecy variables, and backward simulations. Eternity variables are introduced as a more powerful alternative for prophecy variables and backward simulations. This formalism is semantically complete: every simulation is a composition of a forward simula...

Numerical simulation and experimental investigation were used for study of laminar forced convective heat transfer of Al2O3/water nanofluid. Single phase model with temperaturedependent properties was employed for numerical simulation of transport phenomena in nanofluid. The results of experiments and computer-aided simulation indicated remarkable enhancement of convective heat transfer of base...

1. A computer programme is described which simulates energy metabolism in the whole animal. Simulation was based on representation of the animal as a quasi-steady-state system. 2. Input for the programme consisted of the chemical composition of the diet and an estimate of either the maintenance energy requirement or an estimate of energy retention. 3. Simulation was performed by estimating the ...

To achieve the overall objective of restoring natural environment and sustainable resource usability, each forest management practice effect needs to be predicted using a simulation model. Previous simulation efforts were typically confined to public land. Comprehensive forest management practices entail incorporating interactions between public and private land. To make inclusion of private la...
