Digital (or mixed mode) circuit implementations of neural networks bring one major modification to their ideal, defectless models: quantization of the weights dynamics. Would this modification completely perturb the behavior of the network, it will never be possible to implement it on a digital...

The dependence of total population and population distribution on the spatial distribution of the intrinsic growth factor is studied. The existence of solutions of a nonlinear single species and the corresponding predator-prey model is established. The solutions are then approximated by the...

When establishing an imaging system to support a microscopy laboratory, it is important to seek information from individuals who have knowledge of video, audio and computer equipment. The type of camera system purchased may depend upon the type of microscopy performed in the laboratory....

This paper is the sequel of a paper by the authors (1993) and it has a complete version in (1995). We develop a stochastic calculus which allows to integrate non-adapted processes taking their values in the space of second-order 1-forms that are above a manifold valued anticipating process....

The aim of the present paper is to propose an algorithm to easily obtain good estimates of the three parameter Weibull distribution. Our proposed procedure is given in eight steps and it depends on the Simple Iteration Procedure, which always converges, converges fast and does not depend on any...

An electrical power system usually includes machines with their regulators and controls linked through power lines, transformers, capacitor banks, reactors, and loads. In stability analysis, two distinct strategies are possible for solving the differential equations and network equations...

A model of the thalamocortical system was constructed for the purpose of a computational analysis of spindle. The parameters used in the model were based on experimental measurements. The model included a reticular thalamic nucleus and a dorsal layer. The thalamic cells were capable of...

This paper considers the optimal consumption and investiment policy for an investor who has available one bank account paying a fixed interest rate r and n risky assets whose prices are log-normal diffusions. We suppose that transactions between the assets incur a cost proportional to the size...

The pointwise Birkhoff theorem applied with the shift operateur on RN yields a new practical method to compute expectation of functionals in L1(RN). Compared to the classic Monte carlo method the shift turns out to be an efficient process in many aspects, especially when taking account its...
