The digital factory concept is an integrated approach to enhance the product and production engineering processes and simulation is a key technology in digital factory concepts. Different types of simulation can be applied in virtual models on various planning levels and stages to improve the product and process planning. In an advanced stage simulation can be used in the digital factory concep...

A new method for parametric defect modelling is developed for calculating the conditions for activating physical defects in the modules (for example, in library components) of digital circuits. The method affords for the first time the possibility to handle the defects which increase the number of states in the circuit. By using the concept of functional faults, the new method of defect modelli...

1 – This paper is an effort to develop an FPGAbased real-time digital simulator. FPGA is used instead of parallel processors to simulate electromagnetic transients in power systems. A sample single-phase test systems was used to examine the principle. The mathematical model for the power system under consideration is implemented and simulated using Xilinx ISE 4.2 software and ModelSim simulator.

Monte Carlo simulations of digital images of the contrast detail phantom and the ACR phantom are presented for two different x-ray digital mammography modalities: a synchrotron mammography system and a next-generation scanning slot clinical system. A combination of variance reduction methods made it possible to simulate accurate images using real pixel dimensions within reasonable computation t...

The article focuses on one genre of simulations: computer and video games. The author presents a generic model of the elements that co-operate in producing a simulation that is also a game. The model is applied into practice with a case study that focuses on one particularly interesting game: Grand Theft Auto: Vice City (Rockstar Games, 2002), a game that frames its gameplay by simulating certa...

Time-delays (dead times) are found in many processes in industry. Time-delays are mainly caused by the time required to transport mass, energy or information, but they can also be caused by processing time or accumulation. The contribution is focused on a design of algorithms for digital control for processes with time-delay. The algorithms are based on the some modifications of the Smith Predi...

Due to the explosive demands for high speed wireless services, such as wireless Internet, email and cellular video conferencing, digital wireless communications has become one of the most exciting research topics in electrical and electronic engineering field. The neverending demand for such personal and multimedia services, however, demands technologies operating at higher data rates and broad...

This paper deals with simulation of STATCOM used for harmonic reduction with the aid of multilevel VSI circuit. The harmonics in STATCOM due to the voltage ripple are reduced. As a result, the size of inductor and DC capacitor can be reduced. The STATCOM has the great advantage of a fewer number of devices. The VSI is extremely fast in response to reactive power change. The simulation of the ST...

In the art field, the modelling of the symbolic forms through the computer programming and the calculated simulation seems to be a revolution for the state and the status of the representation. How is it made and where is it situated? By effect how to situate and define it, from real to virtual, from mimetism to abstraction, etc? And what is the nature of this new kind of artifice, produced by ...

The Inversion Algorithm is an event-driven algorithm, whose performance rivals or exceeds that of Levelized Compiled code simulation, even at activity rates of 50% or more. The Inversion Algorithm has several unique features, the most remarkable of which is the size of the run-time code. The basic Algorithm can be implemented using no more than a page of run-time code, although in practice it i...
