The home battery energy storage systems (ESSs) are expanding worldwide together with the renewable energy sources (especially solar power plants). As the energy sourced by the different power sources (sun, wind, electrical grid) has to be stored inside the ESS the electrochemical cells&...

For an autonomic power lines inspection robot the energy harvesting system and communication systems are being developed. In this paper the energy harvesting based on toroidal split core current transformer is described. The maximal output power is depend on the current in power li...

In this paper examines procedure for modelling of cardiac output and oxygen consumption as response to cardiopulmonary exercise on a treadmill or bicycle ergometer. The results are presented on 2 athletes - football player and country ski runner which undergone a several stress tes...

This work describes one of the possibilities of amplitude control in recursive sinusoidal digital oscillators with integer arithmetic. As in the case of analog oscillators, it is also necessary to control the amplitude of digital oscillators with a sine wave. If the amplitude is&#x...

This paper compares the different versions of hardware realization of low-cost device for standstill frequency response SSFR testing. The SSFR testing is a modern method used for testing and parameter identification for electrical machines especially for synchronous machines (high power generator...

Long-term usage of photomultiplier tubes (PMTs) led to the discovery of aging effects especially in harsh environment as a radiation is. Aging decreases the efficiency of the PMTs. This means PMTs need to the recalibration after some time. Because CERN´s Large Hadron Collider (LHC)...

It is well known that the heart rate variability (HRV) reflects the activity of the autonomic nervous system. HRV is calculated from heart rate (HR). HR is a nonstationary signal; its frequency variation may contain indicators of current disease, or warnings about impending cardiac...

The timing and synchronisation of the detectors in particle physics play the key role due to the high event rates at particle accelerators. The trigger module in ATLAS Forward Physics project selects the events from time of flight d etector belonging to the proton bunch. ...

This paper examines procedure for static and dynamic modeling of oxygen consumption (VO2) and cardiac output (CO) as response to cardiopulmonary exercise on a treadmill ergometer. It should be noted that the derivation of the subject dynamic model was more difficult due to the ...
