In the last decade, the use of computer simulation models to analyse complex energy and environmental issues has become increasingly important. New environmental regulations for coal-fired power plants enacted in United States and in other countries have a profound effect on power plant design...

Because of round-off error propagation in floating-point arithmetic, any result provided by a computer always contains an error. The Permutation-Perturbation method, also known under the CESTAC (Contrôle et Estimation Stochastique des Arrondis de Calcul) method is a precious tool: (i) for...

The paper describes a simulation case study of a high capacity digital radio link subject to frequency selective fading with M-QAM modulation and different types of channel encoding. The error rate of the uncoded M-QAM digital radio channel is estimated first. Then the performance of the encoded...

The use of time-step-integration techniques to solve for the dynamic response of cable-stayed masts from wind force excitation is examined in this paper. A simulation scheme suitable for generating spatially separated wind force traces that conform to characteristics observed in nature is also...

On a computer, any entry or elementary operation has two legitimate results, one by default and one by excess. Thus, a given algebraic algorithm with a single result is able, when processed on a computer, to generate a large set of floating-point results, all representative of the exact...

The development of a mechanistically valid model is often an objective for modellers of biological systems. This paper briefly considers problems involved in choosing parameter values for biological models, and in determining reasons for model invalidity if it should fail a statistical...

The present paper offers a remarkably simple alternative dynamic finite element computational descriptor for thin plate vibrational capability. The spirit for the proposed displacement version finite element formalism rests upon the problem setup procedure of the recently published automated...

The Fourier analysis of C1-collocation semidiscretization at the Gauss points, for the hyperbolic equation ut + cux = 0, is performed by use of tridiagonal C1-collocation, i.e., a new 3-point finite difference reformulation of the method. The results are compared with Vichnevetsky's general...
