We offer a standpoint that emotions are a necessary mechanism for autonomous control systems. By an autonomous controlled object we understand an object, that is controlled by a control system which is its on-board subsystem. The control system performs learning and control in one process. We develop a methodology of autonomous adaptive control (AAC), that allows us to construct a control system for a given controlled object. As the control goals we take the controlled object survival and the knowledge accumulation. As a whole these goals bring maximization of the controlled object lifetime. We suggest an emotions modeling mechanism (EM). We give the description of its functions and their implementation in AAC methodology. These functions are: (1) a compulsion of the control system for activity; (2) an appreciation of the CO current state at its quality; (3) an appreciation of the formed patterns and their usefulness for control goals; (4) an influence on tempo and depth of reasoning of decision making in current state; (5) providing the decision making subsystem with emotional appraisals of the recognized patterns; (6) providing transfer of information on patterns of emotional appraisals simultaneously with information on the patterns while the organism interacts with another organism.

We present the basis of the original autonomous adaptive control (AAC) methodology. It is an approach to the design of intelligent systems that simulate structure and functions of the nervous system and brain. The AAC methodology idea is that structure and functions of the nervous system are forced to follow the control system conditions at an initial moment. The initial conditions are: (a) the control system (CS) is a discrete device; (b) the CS is located inside of the controlled object; (c) the CS has minimum initial knowledge. We briefly described the AAC CS structure and functions. The AAC CS can be made, for example, in neural networks form.

In this paper, we supplement the set of basic and back-forth behavioural equivalences for Petri nets considered in [11] by place bisimulation ones. The relationships of all the equivalence notions are examined, and their preservation by refinements is investigated to find out which of these relations may be used in top-down design. It is demonstrated that the place bisimulation equivalences may be used for the compositional and history preserving reduction of Petri nets. In addition, we consider all the mentioned equivalences on sequential nets which are a special subclass of general Petri nets modelling sequential systems, where no two actions can happen simultaneously. On this net subclass all pomset equivalences merge with the corresponding interleaving ones, and it allows us to simplify their check.

Object-oriented (OO) software development techniques have gained in popularity as an attractive alternative to the traditional, structured development approach. Fundamental to the OO approach is the object, which bundles data with associated operations in a self-contained unit. The inherently modular object provides an excellent mechanism for creating reusable, stable, and easily maintainable code. In this paper, we present an introduction to OO development; discuss the challenges of large, complex systems; and document the procedures we developed to meet these challenges for our project.

On-line real-time monitoring of marine and operational exhaust stacks and process streams can play a critical role in providing safe, environmentally sound operation of marine and industrial processes using volatile organic species. Monitoring systems are needed that are inexpensive and powerful to be effective. It has been demonstrated that two independent responses, wave velocity and wave attenuation can be obtained from surface acoustic wave devices coated with viscoelastic polymers. This output technique enables identification and concentration determination of isolated species with a single sensor. This paper discusses the development of the sensor devices and the basis of portable acoustic wave sensor systems (which are being used) to monitor volatile organic compounds from marine and industrial chemical processes. Furthermore, on-line monitoring of spray cleaning processes has been effective in quantifying how emissions can be decreased based on substituting solvents, optimizing worker protocols, and utilizing new spray nozzle configurations.

Lack of machine intelligibility in human/computer interactions can be traced to present approaches in software design. From the duality principle, software involved in human/computer software interaction contains two distinct layers, a declarative knowledge-level layer and a lower-level functional or procedural-knowledge layer. The former supports simple deductive and inductive inferences and can be used to facilitate human-comprehensible communication between programs, while the latter is composed of normal procedurally encoded computer programs. The duality principle in software design is necessary in dealing with the demands of wide-scale computer usage in the information age and an urgent goal for computer science research.

In this article a multimedia computer-assisted learning (MCAL) system is presented. The major objective of this work was to investigate the potential of using such systems as tools for transferring instructional course information through various types of computer media as opposed to the classic CAL systems. The philosophy and techniques employed to design the system are investigated. Usage of the implemented system and its merits have been illustrated through its application to teach engineering students and technicians the theory and concepts of marine radar. System design, implementation, test, and revision phases are presented and discussed.
