Navigation is a fundamental research topic in mobile robotics. Wireless sensor networks are providing distributed intelligence to support robot navigation, which effectively reduce the complexity due to dynamic and unstructured environments. For the purpose of efficient routing, a multiple Bloom-filters technique is introduced to support semantic queries and thus simplify the routing problem for a mobile robot. In this paper, we propose a new method for multiple Bloom-filters design using error expectation criterion, which can greatly reduce overall memory usage and produce a uniform relative error expectation for all paths. Simulation results show its effectiveness for multiple Bloom-filters design in comparison with the conventional method.

As the mobile robots and various robot contests became very popular in the last few years, we developed the concept of a novel event for the students of our master module "Mechatronics and Robotics" - a virtual robot contest. The main idea was to allow them to participate in a robot competition and to design control strategies for various robot tasks without having a real robot. Instead, they can use a simulation and a virtual model of a mobile robot F.A.A.K., which was designed at our department. After preparatory stage, the students compete in an online contest with their robot models via Internet. In our contribution, the organization of the robot contest and developed simulation as well as communication tools are presented.

In this paper a new approach on digital controller design based on logic neural networks is presented. In the first part of the paper the logic neuron and its logic function are introduced. Based on this, there is written the general equation for a logic neural network, which allows the easy design of any digital controller directly from the truth table. This solution is validated through MatLab Simulink modeling and simulation and then is implemented in a VLSI chip using PALASM HDL language and also in a ladder diagram PLC device. This method has the advantages of simplicity and flexibility and represents an easy to design modern solution.
In this paper, we present multirate sampling type dynamic quantizers for linear control systems with discrete-valued signal constraints. Although our previous works have derived an optimal dynamic quantizer and verifi...

The paper presents the calculation of the magnetic field in the arcing chamber of the current-limiting circuit breaker of the direct current 1250 A, 750 V. Current-limiting circuit breakers play an important role in electrical low-voltage circuits. Due to the high short-circuit currents it is necessary a very short time to switch off the defective branch. For this the current limiting circuit breakers are conceived as elaborated solutions especially for the arc quenching system, meaning the path of current and the arcing chamber. In this paper the authors present few optimization solutions of some quenching systems which will lead to more performing constructive choices. The finite element software package ANSYS is use for calculation of the magnetic field components.

The experiments aimed to compare data driven models for the valuation of residential premises were conducted using KEEL (Knowledge Extraction based on Evolutionary Learning) system. Twelve different regression algorithms were applied to an actual data set derived from the cadastral system and the registry of real estate transactions. The 10-fold cross validation and statistical tests were applied. The lowest values of MSE provided models constructed and optimized by means of support vector machine, artificial neural network, decision trees for regression and quadratic regression, however differences between them were not statistically significant. Worse performance revealed algorithms employing evolutionary fuzzy rule learning. The experiments confirmed the usefulness of KEEL as a powerful tool with its numerous evolutionary algorithms together with classical learning approaches to carry out laborious investigation on a practical problem in a relatively short time.

Possible contribution and limitations of model predictive controller are discussed for special case of thermostatic bath temperature control. The control potential is restricted because of constrained heating and cooling manipulated variables. The aim of the paper is to find out which knowledge and requirements can improve control and try to compare predictive controller with some traditional control approaches for given specific thermal process. Base predictive controller uses information about MIMO system dynamics and constrains. The control response of such a controller is unfortunately similar to known simple approaches. control with predictive controller became beneficial after additional information (future set-point knowledge) and other requirements (minimal energy cost - optimal steady state energy consumption) were used.
