{ The paper describes progress in the modelling of penetration and coupling in conngu-rations relevant to EMC. The application of the TLM method in modelling eeciently thin nite-conductivity panels and thin wires is outlined. Comparisons with experimental and theoretical results show that inexpensive numerical models are accurate enough for EMC studies and hence that whole system modelling is b...

Introduction: It has been estimated that the total number of meteoroids entering the Earth's atmosphere with masses above 1 kg is about 37000 per year [1]. And approximately 4400 events with mass more than 1 kg strike the Earth every year [1]. Among these im-pactors, those in the mass range ~10 4-3.10 6 kg fragment and form crater fields, with the largest crater resulting from impact of the lar...

The Vlasov equation describes the evolution of the distribution function of particles in phase space (x, v), where the particles interact with long-range forces, but where short-range " collisional " forces are neglected. A space plasma consists of low-mass electrically charged particles, and therefore the most important long-range forces acting in the plasma are the Lorentz forces created by e...

It is known that the analyses of complex structures can be affected by a great uncertainties and approximations. The paper schedules these approximations in three groups: numerical errors, modelling errors and human errors. After a brief discussion of these approximations, the paper put in evidence the importance to planning the numerical analysis of complex structures using different models, v...

Over the years, considerable efforts have been made to study the performance of Submerged Entry Nozzle (SEN) and mould of continuous slab caster. Numerous physical and numerical modelling studies have already been carried out and reported in the literature to study the fluid flow behaviour inside the mould. Based on the extensive literature search, a summary of these is presented here. For the ...

The subject of geometric modelling is a blend of different types of geometry, some mathematical modelling, some numerical analysis, and discipline specific applications. In these course notes, we will concentrate of the subdiscipline of geometric modelling known as computeraided geometric design, which was formed from the mathematical structures and methods used in CAD/CAM systems and subsequen...
