Multiparametric optical assay (MOA) can provide further progress in studies and control of natural disperse systems (DS) such as water and air. MOA includes the nondistructive analysis of DS by different optical methods such as refractometry, absorption. fluorescence. light scattering (integral and differential, static and dynamic. unpolarized and polarized). Taking into account an optical theory and modern technologies of data interpretation can help to elaborate methods for on-line optical control of complex DS. it is in accordance with fiber optics development. Bank of optical data for DS (BODDS) is an informative base of MOA. The goal of BODDS is computer processing of DS analysis, systematization, statistical study of data and solving of inverse physical problems by different ways. At the analysis of unknown polycomponent DS. for example, water with dangerous impurities of oil. bacteria or viruses. etc. the comparison of measured parameters with known one can help us to identify the unknown system.

Effective numerical models of induction heat treatment are developed. They include two-dimensional modeling of coupling electromagnetic and temperature fields in cylindrical systems for processing of tubes and rolls. Also thermal tension during heating and cooling of tubes and rolls are simulated. These data allow defining structure, hardness, the size of grain and other properties of the tubes and rolls. They allow optimizing design and a choice of equipment, a heat treatment mode for the purpose of achievement of the maximum quality and minimization of energy consumption. The developed two-dimensional models were used not only for the design of induction heat treatment systems of tubes and rolls, but also for a digital control of these complexes.

This paper presents the experience of lberdrola (Spain) and EA Technology (UK)in the development and use of expert systems applied to the control/supervision of electricity networks. The need to expand the scope of their existing stand-alone expert system by integrating new information and new capabilities has moved these two companies to enter the emerging area of Distributed Artificial Intelligence (DAI),joining forces in the ESPRIT project ARCHON the objective of which is to produce a general framework for cooperating expert systems. The main objectives of the lberdrola application are disturbance detection, identification of permanent faults, evaluation of network status, preparation of a restoration plan and tracking of network evolution. The EA Technology application integrates fault diagnosis both at high and low voltage, security analysis, generation of safe switching schedules, lighting detection and collates information between these individual systems. Both applications are structured as a set of semiautonomous heterogeneous agents.
modeling scattering structures of various shapes using the method of moments (MoM) with wire grid (WG) models remains crucial in contemporary research. Although many publications focus on WG models constructed with sq...

The implementation of projects for the system of supply and distribution of air in waste management has shown the need to create a mathematical model that would describe in general terms the behavior of gas flows under natural aeration and forced aeration in heterophase media (arrays of different nature). This model would be a necessary addition to chemical kinetics models describing the process of biodegradation of organic matter. One of the criteria for this process is temperature and time characteristics, its relationship with the degree of oxidation of organic matter, accumulation of organic carbon, carbon dioxide content, etc. If we know the nature of temperature changes over time, it is possible in the first approximation to control the course of the process by adjusting the air supply, the intensity of mixing, the degree of moisture, the additional introduction of multifunctional additives, etc. The paper describes the automated waste management system using gas-contact technologies. Gas flow management requires consideration of a huge number of parameters, besides the ones listed above, as well as the creation of generalized criteria for assessing the state of the system. These parameters are classified into the following groups: mechanical (strength), water-filtration and air-filtration, temperature, as well as chemical and biological, and summarized in a multidimensional data file. However, not all of the parameters included in the listed groups are central to the creation of generalized criteria for the choice of technology. Therefore, the decision maker (DM) indicates which parameters are more important and which are not, that is, selects the levels (you can choose different ones each time depending on the situation). To make the right decision when assigning a level, there must be an adequate control algorithm. Based on this algorithm, the automated system should allow one to process a large amount of data and suggest a solution. Then the automated cont
