The aim of this research was to determine an acceptable method of texture feature extraction that could be used for a visual inspection of ceramic tiles quality. Traditional extraction of statistical features has been carried out as well as feature extraction based on local binary pattern operators. For the purpose of testing the proposed methods good and defective ceramic tiles have been identified. The obtained results indicate a possibility for developing a system of a visual inspection of ceramic tiles quality and point out local binary pattern operators as a powerful tool applicable in this particular case.

The paper suggests a stochastic approximate solution to scheduling problems with unrelated parallel machines. The presented method is based on neurodynamic programming (reinforcement learning and feed-forward artificial neural networks). For various scheduling environments (static-dynamic, deterministic-stochastic) different variants of episodic Q-learning rules are proposed. A way to improve the avoidance of local minima is also discussed. Some investigations on the exploration strategy function approximation and parallelizing the solution are made. Finally a few experimental results are shown.

A multiobjective optimization procedure for the design of interior PM motors based on Differential Evolution algorithm is presented. A comparative analysis has been carried out for the optimized 5 kW, 50 kW and 200 kW IPM motors with two and three layers of cavities in the rotor to show design tradeoffs between goals to minimize the motor volume while maximizing the power output in the field weakening regime with the back emf constraint as the main limiting factor in the design. The finite element method has been used to calculate the motor parameters during the optimization process. The effectiveness of the proposed design methodology has been shown on a 1.65 kW IPM motor with two layers of cavities in the rotor for which a prototype has been built and tested.
The paper examines the conditions for isolating the unknown input detection from the effects of the measurements noise in the important family of positional control problems. The study is motivated by the need of impr...

The control of dynamical systems with inherent non-linear characteristics has motivated research in non-linear control theory. Two main approaches to dealing with uncertainties in control systems design are adaptive and robust control. In this paper, discrete direct adaptive control of unknown non-linear SISO systems is considered. The controller is implemented using a fuzzy neural network. The control concept is tested on a laboratory pilot plant and compared to a standard discrete PID Takahashi controller

This paper presents an evolutionary communication model that makes use of neural networks and evolutionary computation. It is embedded in a simple two-dimensional artificial world. The work builds on the successful approach of Cangelosi (1997) but is designed with considerations of suitability for extensions of more elaborate communication.

The concept of FB based on newly appearing standard IEC 61499 originates in automationengineering and corresponds to the distributed control structure. A FB represents an abstraction of a software functional unit comprising an individual data structure and associated operations. To support the mature of the FB-related design paradigm in this paper, we discuss the specification of FBs and FB applications in UML. The paper suggests three types of models which have the purposes of general specification, automated code generation and test case generation. The first and second models are specified in UML while the third one is to be formalised in certain formal language. We focus on the first two model specification in this paper which transform FB-related elements in UML expressions. This shows that the rich resources provided for UML can be applicable to FB paradigm. The characteristics and the potential use of the model are discussed.

This paper proposes a new kind of auto-climbing robot which is used for cleaning the spherical surface of the newly built National Grand Theatre in China. Firstly, an overview of the robotic system is given. Then for system design and control purposes, the climbing process is studied in detail. The force distribution of the front and rear supporting mechanisms is computed in a way that ensures the safety of the climbing process. After that, a new approach to path planning for wall-cleaning robots is presented considering the movement security, cleaning efficiency and the percentage of cleaning coverage. The successful on-site test confirms the principles described above and the robot's ability to work on a spherical surface
