In this paper modelling and analysis of the SRM torque characteristics including torque ripples are described. Optimal control strategy based on genetic algorithm (GA) to minimize torque ripple is proposed. The optimization criteria depend on choosing the exact current profile based on the optimal excitation parameters which govern the torque shape. The model and control are carried out on high...

Nowadays, the globalization is one of the most significant phenomena of contemporary life. There are many debates about the real meaning of the globalization, its roots, effects and future. Among the most important aspects of the globalization is surely the global transportation system. In this framework it is clear how the availability of an advanced integrated transportation system, for movin...

In this paper, we investigate the use of logic-based multi-agent systems for modelling active environments. Our case study is an intelligent support system for a so-called “active museum”. We show the approach of structuring the “agent space”, i.e., the social organisations acting within the environment, is well fitted to naturally represent not only the physical structure of the application, b...

This report focuses on a problem within the area of Intelligent Tutoring Systems; that of analysing student’s reasoning (student diagnosis). A novel approach to collecting information for this analysis, complementary to traditional student modelling techniques, is presented. This technique is based on using a Learning Companion, a computer based agent, as a collaboration partner to the student....

This paper investigates an approach to providing a general-purpose authoring/tutoring shell for intelligent computer assisted learning systems. The approach is to outline an object-oriented representation of task/goal hierarchies, then to consider the ways in which domain expertise, student information and teacher expertise can be made to interact with such hierarchies. The result is a skeleton...

Nowadays, product information is being a key issue for traceability and quality management but also for state-of-the-art technologies such as intelligent product technologies. From this statement, product information design and management are becoming one of the most important steps in order to control quality of services and products that aims at customer satisfaction. However, there is no rea...

Due to the vast and rapid increase in the size of data, data mining has been an increasingly important tool for the purpose of knowledge discovery to prevent the presence of rich data but poor knowledge. In this context, machine learning can be seen as a powerful approach to achieve intelligent data mining. In practice, machine learning is also an intelligent approach for predictive modelling. ...

This paper discussed the use of Conceptual Graphs (CGs) for implementing tasks employed in web-based educational systems that aid terminology learning. Specifically, we focus on two critical issues in intelligent tutoring student diagnosis and generation of adaptive explanations. Both tasks are demonstrated in terminological domains where learners have to familiarize themselves with concepts in...

Process modelling is and should be goal-oriented. The formal statement of modelling goals in current process modelling practice is either forgotten, somehow considered implicitly, or vaguely remembered at some later point in the model building cycle. This lack of explicit goal statement greatly affects the focus, task efficiency, model parsimony and the termination of the modelling cycle, espec...

Original scientific paper This paper proposes a Neuro-fuzzy system for quantitative assessment of the effects of intelligent transportation systems and technologies on road fatalities. The basic idea in developing Neuro-fuzzy system is the fact that intelligent transportation systems and technologies activate some safety mechanisms and in turn the activation of safety mechanisms will have a pos...
