The Axiom language is based on the notions of “categories”, “domains” and “packages”. These concepts are used to build an interface between symbolic and numeric calculations. In particular, an interface to the NAG Fortran Library and Axiom's algebra and graphics facilities is...

The work deals with the representation of the concepts of program package PIDMaster for the signal analysis, system modeling and controller's synthesis. It is distinguished for the user-friendly interface which enables comfortable work for the less experienced users also. The required...

A numerical model of an axisymmetric confined diffusion flame formed between a CH4 jet and coflowing air is presented. The model utilizes the flame sheet concept to locate the stoichiometric fuel-oxygen interface and,hence, the points of heat release. The numerically simulated steady-state flame...

This paper presents a new method to control elastic-joint robots. Models that include electrical and mechanical parts of actuator dynamics, together with joint elasticity are considered. A novel nonlinear coordinate transformation is introduced. It is possible after the transformation to exactly...

Numerical programs are often difficult to use for people who were not involved in their development. Knowledge necessary for the use of the program can be included in a user interface. Often, further improvements are possible when the user interface gives the appropriate support. The user task...

This paper is intended to demonstrate the use of numerical grids generated by spectral techniques in the solution of the Navier-Stokes equations also obtained by using spectral techniques. This effort thus extends the applicability of spectral techniques to arbitrary domains. In this paper, only...

Work to develop a robust knowledge-base for the automated construction of numerical algorithms is described. The approach adopted is one of synthesis of an algorithm from a library of pre-formed sub-components. The target domain for the system is Finite Element Analysis of incompressible fluid...

Process supervision takes place on top of classical control, and monitoring, and Qualitative Supervision and Diagnostics is an attempt to formalize operator skill and process knowledge, as well as the heuristics about the evaluation of the behaviour of the complete system. The Qualitative...
