作者： M Nowak M Baier Silesian University of Technology Faculty of Automatic Control Electronics and Computer Science 16 Akademicka Street 44-100 Gliwice Poland Silesian University of Technology Faculty of Mechanical Engineering 18A Konarskiego Street 44-100 Gliwice Poland

The paper covers issue of conducting advanced research of electrical race car participating in international competition called Sileverline Corporate Challenge. Process of designing race cars in Silesian Greenpower team is aided by a professional engine test stand built particularly in purpose of this research. Phase of testing and simulation is an important part of the implementation of new technologies. Properly developed solutions and test procedures are able to significantly shorten development time and reduce design costs. Testing process must be controlled by a modular and flexible application, easy to modify and ensuring safety. This paper describes the concept of object-oriented programming in LabVIEW and exemplary architecture of object-oriented control application designed to control engine test stand of the electrical race car. Eventually, the task of application will be to steer the electromagnetic brake and the engine load torque to perform according to data from the actual race track. During the designing process of the car, minimizing energy losses and maximizing powertrain efficiency are the main aspects taken into consideration. One of the crucial issues to accomplish these goals is to maintain optimal performance of the motor by applying effective cooling. The paper covers the research verifying the effectiveness of the cooling system.

Selected Problems of Electrical engineering and Electronics (WZEE)

The variability of electromagnetic parameters of induction motors with deep-bar cage or solid rotors is represented, with a satisfactory approximation, by the machine secondary multi-loop equivalent circuit with constant lumped parameters. An estimation procedure of electromagnetic parameters of such an equivalent circuit is presented in the paper. The procedure is carried out using the measured frequency characteristic determined on the basis of instantaneous values of investigated induction motor electromechanical quantities. The study has been subjected to an induction motor with a solid rotor manufactured from the magnetic material, i.e. a machine characterized by a significant skin effect occurring in rotor solid conductive elements.

An artificial vision solution for reusing discarded parts resulted after a manufacturing process

Asachi' of Iaşi - Romania Faculty of Machine Manufacturing and Industrial Management Department of Machine Manufacturing Technology Blvd. Mangeron No. 59A 700050 Iasi Romania Tehnical University 'Gh.

The profit of a factory can be improved by reusing the discarded components produced. This paper is based on the case of a manufacturing process where rectangular metallic sheets of different sizes are produced. Using an artificial vision system, the shapes and the sizes of the produced parts can be determined. Those sheets which do not respect the requirements imposed are labeled as discarded. Instead of throwing these parts, a decision algorithm can analyze if another metallic sheet with smaller dimensions can be obtained from these. Two methods of decision are presented in this paper, considering the restriction that the sides of the new sheet has to be parallel with the axis of the coordinate system. The coordinates of each new part obtained from a discarded sheet are computed in order to be delivered to a milling machine. Details about implementing these algorithms (image processing and decision respectively) in the MATLAB environment using Image Processing Toolbox are given.

Genetic algorithms (GAs) are optimization techniques inspired from natural genetics. A genetic algorithm has in view to evaluate many points in the parameter space with the aim to converge to the global optimal solution. Mathematica software is an excellent symbolic tool for hard tasks and is used in this paper. Proportional Integral Derivative (PID) control is very important for the quality of robust control, new approaches as symbolic to genetic tuning of PID controllers are excellent choice to solve this problem. A global integral index ISE (Integral of Squared Error) is minimized. At first the PID Symbolic Tuning is considered. The complicated problem of robust genetic tuning is solved. Some examples obtained by simulation are considered in both cases.

In this paper are presented several techniques used for improving the pupil detection algorithm based on a head mounted eye tracking system employing an infrared video camera. The coordinates of the eye pupil center obtained by any eye tracker device are affected by many noise sources. In order to improve the pupil detection position, several different techniques of real time filtering and high frequency spikes canceling from the signal provided by the pupil detection algorithm are presented. The optimal parameters of the real time filter, depending on the application sampling frequency, have been determined.

Wireless sensors networks is an active research topic. The sensor nodes (i.e. motes) are the main building blocks of these networks. There is a permanent concern for building more and more efficient motes in order to satisfy the demanding specifications of a sensor network. This paper introduces a new mote device: aceMOTE which is based on a 32 bit microcontroller. The hardware structure of the mote is presented and a comparison is made with similar popular devices. An experimental analysis is made regarding the energy consumption and the results prove that a 32 bit microcontroller is a viable choice for usage in mote design compared with the more frequently used 8 bit and 16 bit microcontrollers. © 2014 IEEE.

Modern, based on biomedical signals interfaces have become recently very complex, however the complexity does not always lead to increased functionality or usability. In particular, when it comes to handicapped users, the currently available solutions are far from satisfactory. In this paper an innovative approach for biomedical signals based interfaced with the implementation of an inexpensive gaming headset Emotiv EPOC was presented. The main goal was to design, and develop an intuitive and user-friendly interface based on implementation of various biomedical signals such as EEG or EMG. The project was primarily intended for handicapped users as a replacement for traditional interfaces such as keyboard or mouse, however its potential use was extended. The proposed system differs from the already existing interfaces mainly because of its versatility to work with various biomedical signals, thus enabling a single interface to be controlled with different devices. Initial investigation has proven that Emotiv EPOC headset could be applied as an inexpensive, easily available on the open market tool for Human-computer Interaction (HCI) systems for the gaming purpose.

This paper shows how control techniques, such as PID or generalized predictive control, can improve the performance of TCP/IP networks when dealing with congestion. Drop tail, or more sophisticated AQM techniques such as RED, perform worse than process control techniques. A comparison between the different methods in different working scenarios is analyzed. Two different GPC controllers are evaluated. One considers the model resulting from on-line identification and the other is the linearization of the non-linear model. © 2009 EUCA.
