摘要:

AbstractModern simulators represent a combination of very sophisticated mechanical fixturing driven by hydraulic actuators under computer control. So state-of-the-art techniques and tecluiology are required to build and operate such systems.[4 5] That is why the problem of designing such simulators becomes a very important issue. This article explores some approaches in analysis of multi-axial road simulators designed and built by MTS Systems.

摘要:

AbstractSources, coupling mechanisms, and receivers of electromagnetic Interference (EMI) in DC electrified rail-transit systems are described, and models for each are proposed. Computational algorithms for predicting the level of EMI are considered, and a discrete time step simulation method is presented that relies on the difference equation technique.

摘要:

AbstractIn this paper we explain the theory of the finite element method and give the formulae for the resolution of the problems based on Poisson's equation. Moreover, we fully explain all the steps necessary to the study of a plane field and introduce new procedures and methods able to reduce computation time and memory employment. These procedures are applied to some examples for the resolution of two-or three- dimensional and axisymmetric fields by means of a microcomputer.

摘要:

AbstractA non-Gaussian long-term model (KAPPAG-T.T) for atmospheric dispersion simulations is presented. The model is based on a two-dimensional analytic solution of the advfiction-diffus ton equation for shear flows. The vertical inhomogeneity of the atmospheric boundary layer is accounted for by power laws for wind velocity and eddy diffusivity profiles. Performances of KAPFAC-LT model in estimating annual ground-level mean concentrations are compared to those of EPA regulatory model ISCLT forcases involving anelevated point oonrce.
