Many modern continuous system simulation tools provide good facilities for the efficient implementation of simulation models and for interactive experimentation using a simulation model. In most cases, however, the environment lacks some important features which can greatly assist the user in...

The functional properties of a neuron can be simulated by electrical circuits. This technique is of use for natural as well as for electrical stimulation. In particular, a new model is proposed which shows the influence of the myelinated parts of the neuron.

In this paper, Tikhonov's regularization method and the numerical continuation method are combined into a stable and widely convergent numerical method for determining the resistivities of the earth in the mathematical model of electrical log. Numerical simulations are earried out to test the...

Described in this paper is a novel approach for the object-oriented computer modelling of vehicle dynamics. The key feature of the method is to represent the mechanical system as a collection of concatenated transmission elements carrying out component-related tasks autonomously and in a...

We present a new method based on wavelet transform for the estimation of the power spectrum for a class of non-stationary signals arising in the analysis of random media. Using a convergence result for this signal we can reduce the estimation of the power spectrum to the estimation of only two...

In this paper we first discuss the different assumptions used for the graphical analysis of dynamical systems arising from linear bond graph models. Secondly we propose a descriptor formulation of such dynamical systems defined by the constitutive relations of the elements and a basis set of...

Single cells consist of thousands of different compounds and reactions. Evolution theory tells us that none of these compounds or reactions are useless for the cell. Keeping this in mind, the question is addressed on which basis a selection of state variables and of relation between state...
