The problem caused by the representation of different types of events in discrete simulation is discussed and a solution based on their dual nature is presented.

Vehicle simulators traditionally model a vehicle's components separately. This paper describes a “holistic” simulator that constructs a map of fuel consumption vs speed, acceleration, and gear for the vehicle as a whole, based on statistical analysis of road test data. A single computer...

In this paper a technique in given for the simulation and implementation of comb filters. An apropriate discrete model of the comb filter is choosen and through simulation technique are calculated and optimized its parameters. As it is known comb filters are used for different applications...

The main purpose of this work is to establish necessary conditions and sufficient conditions for the existence of a solution of matrix equations whose coefficient matrices have elements belonging to the ring R=C[z1,z2,…zn] of polynomials in n variables with complex coefficients and the ring...

Phosphate in waste water disposed in the field can be partially or wholly retained in soil, eliminating ground water pollution. The retention ability of soil is affected by many factors, such as soil pH, minerals, structure, water content, solute concentration, solution pH, etc. The flow rate of...

The Hybrid Computer Research Center of the National Research Council of Italy carried out a Digital Differential Analyser, the PMICE, whose architecture has been object of previous works. In the present paper the Authors want to inspect the PMICE from the User point of view: a quick tracking...

An alternative approach to state estimation problem in linear, time-invariant dynamic systems is presented in this paper. The approach developed first identifies the initial state of the system by using a proportional plus integral parameter identification method. The Lyapunov design technique...

The correct method for applying the von Neumann stability analysis to composite finite difference schemes for numerical solution of partial differential equations is investigated. Our results provide justification of the hopscotch method and give correction to earlier analyses [1,7]. The methods...

The numerical software users are often perturbed by accuracy problems imputable to the rounding errors generated by computer hardware. M. La Porte and J. Vignes (4) created the permutation-perturbation method for evaluating the validity of the solutions of linear algebraic systems, detection of...

A sample is chosen deterministically from an input distribution to a simulation system. Under certain conditions the mean of the system output sample is equal to the true output mean (up to computational errors). Slightly more stringent conditions guarantee that the output sample variance is...
