Electromagnetic field simulators have become a widely used tool in a design process of microwave circuits and systems. A proper usage of electromagnetic (EM) field simulators allows substantial reduction of the design time providing reliable results. In such case the required parameters of the designed circuit can be reached even at the first manufactured prototype in spite of high complexity o...

We deal with problems arising in the coupling of process and device simulators. It is analyzed what kind of data and algorithms such simulations are based on. An overview of existing technology computer-aided design data models is given. A generic object-oriented data model suitable for three-dimensional process and device simulations, the so-called WAFER-STATE-SERVER is presented. By taking ad...

In this paper we study message flow processes in distributed simulators of open queueing networks. We develop and study queueing models for distributed simulators with maximum lookahead sequencing. We characterize the “external” arrival process, and the message feedback process in the simulator of a simple queueing network with feedback. We show that a certain “natural” modelling construct for ...

Modeling and simulation is one of the essential aspects in the robots research field. In order to understand the importance of the graphical simulation it is necessary to consider why and where the simulation systems are mainly used. The industrial tendency is to develop simulation systems, which could be of help for the systems (robots) off-line control and for the robot operational workspace ...

Formal technology-based training can be costly for all concerned. Efficient and effective alternatives to face-to-face training need to be found. One option is to use equipment simulators before undertaking formal training so that hands-on training can be conducted at a more advanced level and thereby increase efficiency. Case studies using Global Positioning System (GPS) simulations were condu...

This work describes a general framework for the prediction of industrial sustainability integrated with process simulators. Even if sustainability is a complex concept, it can be estimated using some indicators or metrics. Two kinds of sustainability indicators are used in the present work: (i) threedimensional indicators (3D-indicators) and (ii) one-dimensional indicators (1D-indicators). The ...

Simulator fidelity has been defined as the conformance of a flight simulator to the characteristics of the real aircraft. Objective fidelity evaluation is an engineering approach that attacks the fidelity problem with comparison of simulator and the actual system behavior over some quantitative measures. Testing can be pronounced as the fundamental mean for this comparison. From the utilization...
