The paper is concerned with the comparison of four basic control strategies of the on-board energy storage system. The energy storage system is able to increase the tram efficiency and decrease operating costs. The comparing criteria are energy savings of strategies. Energy savings are calculated via stochastic model of the real tram line. Return on the investment is also estimated in this paper.

This paper deals with the design and construction of a switching power supply which is intended for direct resistive heating of iron components. The power supply is especially intended for resistive heating of horseshoes. The supply is able to deliver an output current of up to 1600 A at a power of up to 2500 W. The chosen topology, design parameters and control strategy are included in the contribution. Specific construction of the pulse transformer with respect to minimum leakage and details of the secondary synchronous rectifier are described. Finally measurement results are presented and operation details are introduced and documented with the measurements. The power supply was successfully tested and the required output parameters were met. However some problems do exist, especially with contacting the heated component to the output leads of the supply. The power supply can be used as an alternative solution to classic means of iron heating. The methods and ideas presented in this work can be applied in a design of a similar power supply with high output current, but most of the design rules are valid generally for the given topology.

In this study, a robot arm that can imitate human arm is designed and presented. The potentiometers are located to the joints of the human arm in order to detect movements of human gestures, and data were collected by this way. The collected data named as “movement of human arm” are classified by the help of Artificial Neural Network (ANN). The robot performs its movements according to the classified movements of the human. Real robot and real data are used in this study. Obtained results show that the learning application of imitating human action via the robot was successfully implemented. With this application, the platforms of robot arm in an industrial environment can be controlled more easily; on the other hand, robotic automation systems which have the capability of making a standard movements of a human can become more resistant to the errors.

Systems grow in complexity but their behavior has to meet the specifications and to be robust in all or most situations and conditions. When variations affect more responses of a system, achieving robustness becomes a hard to fulfill task because different responses may demand concurrent settings for the system's factors. In this paper, we approach multi-response robustness optimization by estimating the dependence of the response distribution on some controllable factors. The estimation is made based on a number of simulations with different factors settings and it is able to predict the response distribution. We used three methods for choosing the optimal factor settings. The first uses a weighted cost function based on the importance of each response, while the last two methods constraint the factors space by imposing a restriction for each response. The methods are applied on a beam-leveling system used in automotive and proved to be successful even if the number of heterogeneous factors is greater compared with other systems used in literature. The optimal settings are validated by comparing the estimated cost functions with the simulated ones.

The nonlinear beam with vertical combined excitations is proposed as an energy harvester. The system is modelled as a cantilever beam with included a tip mass and piezoelectric patches which transduce the bending strains induced by both, the harmonic and as an additive stochastic forces. The excitation affects in vertical directions by kinematic forcing into electrical charge. The main goal is to analyse the dynamics of the electro-mechanical beam system and the influence of the mixed excitation forces into an effectiveness of the energy harvesting. Overcoming the potential barrier by the beam system is also analysed, where large output amplitudes occur. Such region of the vibration affects more power generation as well as voltage spikes, which is crucial in terms of load resistors sensitivities. By increasing the additive noise level with fixed harmonic force we observe the transition from single well oscillations to inter-well stochastic jumps, and the output power is measured during different system behaviours.

In order to determine position, GPS receiver needs to know navigation message which is obtained by demodulating received signal. Demodulating process requires the local harmonic signal and received signal must have pretty good phase alignment. So the phase locked loop is employed to track phase of received signal. This paper implements the phase locked loop to track the GPS signal. Basic principle of phase locked loop signal is presented. Then different types of phase locked loop with different architectures and types of the filter are implemented. Results of implementation show performance of the loops. The tracking loop is carried out in MATLAB using samples of intermediate frequency signal recorded from a GPS front-end.

Light-emitting diodes (LED) has been developing rapidly during recent years due to the advancement of technology driven by the global demand of reducing carbon dioxide emission to the atmosphere. Meanwhile, various kinds of corresponding LED products has been generated and widely used in many fields, e.g.. However, how to improve the luminous efficiency is the challenge in LED industry. And the problem is closely related to PN junction cooling, which becomes more prominent. To solve this problem, a new type of heat dissipation structure is proposed in this paper, which uses a new kind of heat pipe - bionic transpiration heat pipe with high thermal efficiency. In addition, the simulation used ANSYS Icepak on basis of this model will show the advantages of the system we design in details. Furthermore, the application of the present design can further broaden the application fields of LED in IT, military, machinery,aviation and so forth.
