The different features of MATLAB Toolboxes used in the analysis of power systems are described. Software introduces SIMULINK environment of MATLAB for implementing user friendly and future expansion. To illustrate the capabilities of SIMULINK simulation tool, a case study based on a...

In this paper we will give a brief overview of the physical modeling language Modelica, present the modeling and simulation environment MathModelica, and describe some industrial projects where MathModelica has been used.

Verilog-2001 added many valuable enhancements to the IEEE1364-1995 Verilog Standard, but when can we safely use them? When the full suite of tools used by your company to do design all support Verilog-2001 enhancements, your company can safely start taking advantage of the enhancements. This paper details a number Verilog-2001 coding examples and indicates which simulation tools support the enh...

Well capture zone determination and site remediation has led to an increasing need of understanding how to quantitatively characterize both the heterogeneity of gravel aquifers and the influence of heterogeneity on groundwater flow and solute transport. Models play an important role in decision-making processes, especially in the context of better characterizing and in forecasting the behavior ...

Job Definition Format (JDF) is a relatively young industry standard that specifies a workflow model and a data format for describing print jobs and exchanging production information. Although most vendors today offer JDF-enabled products, little research has been conducted aiming at measuring the benefits of using JDF in production. One reason for this is likely the lack of suitable tools. This...

The decision-making process is a very essential part of any construction operation. Simulation can be used as a tool to assist construction managers in making informed decisions. In this paper, simulation is applied to a Concrete Batch Plant to analyze alternative solutions and resource management. Data is collected to define activity durations for the plant. A simulation model is constructed f...

21 Distributed Virtual Environments simulate the behaviour and activities of a great number of users 22 interacting in a virtual world over a wide area network. The size of the virtual worlds and the 23 tremendous number of users that these environments are called to support require additional 24 bandwidth and computational resources. For supporting large-scale Distributed Virtual 25 Environmen...

This paper describes NESSY (NEtwork Simulation SYstem). This software tool aims to deal with the main problems in the area of performance evaluation simulation tool for communication networks. The tool provides an object oriented methodology in order to represent network components. The assembly of these components is then used for building a network model. Furthermore, the tool relies on a for...

Nowadays is extremely important to monitor and analyze the urban environment and in particular the urban viability. The increasing availability of computational power, together with more efficient simulation algorithm allows real time modeling of even complex systems such as urban traffic. Information and simulation are at the basis of the decisional process for policy makers at global and loca...

A dynamic computer simulator was developed to study planetary rover mobility. The simulator was validated for step-obstacle negotiation by comparing simulation results with a quasi-static analysis of a rockerbogie suspension. In addition, sample rover wheels were constructed and experiments were carried out on a single-wheel testbed to help validate the simulator. It is concluded that to fully ...
