The on-line estimation of derivatives is of fundamental importance in gradient-based routing algorithm for data networks and other applications. Smoothed perturbation analysis as proposed in this paper requires minimal knowledge about the system statistics. It is shown that smoothed perturbation...

The article considers the nonlinear optimal impulse control problem of a dynamic plant in which, besides the traditional energy limitation, restrictions are imposed on the number of impulse actions and on the impulse repetition rate.

A Volterra integro-differential equation is said to be stochastic (SVIDE) if it involves any possible combination of (i) random coefficients, (ii) random initial conditions, (iii) random forcing functions, (iv) random kernels. Here stochastic Volterra integro-differential equations are...

This paper is concerned with the management of complex projects, and identifies a research approach to develop a project management training and support system. It adopts a methodology which differentiates between deep and surface knowledge, proposing the use of an appropriate qualitative...

This paper focuses on the modelling and simulation of a planar serial five-link system resembling a headless water-skier. The water-skier is taught to water-ski by an informal gradient method. The informal gradient method determines the parameters associated with control moments applied at the...

A simple approach to the development of user-friendly software for the bounded-error approach to parameter estimation is offered. It enables the computer determination of the boundaries of the set of all parameters satisfying the bounded-error constraints, whether the problem is linear or...
