✦ Synopsis

Tessem, B., Approximations for efficient computation in the theory of evidence (Research Note), Artificial Intelligence 61 ( 1993 ) 315-329.

The theory of evidence has become a widely used method for handling uncertainty in intelligent systems. The method has, however, an efficiency problem. To solve this problem there is a need for approximations. In this paper an approximation method in the theory of evidence is presented. Further, it is compared experimentally with Bayesian and consonant approximation methods with regard to the error they make. Depending on parameters and the nature of evidence the experiments show that the new method gives comparatively good results. Properties of the approximation methods for presentation purposes are also discussed.

## Abstract We develop a model of marketing efficiency based on a directional distance function that allows for marketing spillovers. A parametric model is used to test for spillovers from rival marketing and from a firm's marketing activity of its other related products. We then show how this info

## Abstract In this paper we propose a variational method to find out piecewise‐linear (PWL) approximations of non‐linear dynamical systems in view of their circuit implementations. The method is based on some significant trajectories of the dynamical system and provides reasonably accurate PWL app

Using Laplace transforms, analytical approximations are obtained in a simple way for the probabilities of charge transfer between donor and acceptor states coupled by a bridge. As a test, these are compared with accurate and numerical calculations when the bridge is treated as a standard diatomic Hu
