Exploring the influence of pressure on the life of lead acid batteries for hybrid electric vehicles
Pospíchal, Martin ; Tošer, Pavel (referee) ; Bača, Petr (advisor)
The lead-acid batteries used in hybrid electronic vehicles HEV operate in high-rate mode in a state of partial charge PSoC. It occurs when the degradation mechanisms related to irreversible sulphation and negative electrodes are a limiting factor in the life of lead-acid batteries. The electrode system was applied to experimental pressure cells of different sizes. Exp. cells were subjected to measurement and evaluation of potential negative electrode, a negative active mass resistance, contact resistance of transition collector - the active mass with the evaluation and measurement of pressure fluctuations within four PSoC runs.

Then comes after the description of the several metered and biased parameters and its impression on the quality and level of the recieved signal. The experimental part deals with the metering of the several parameters, that contains the description of the laid metering constellation diagrams, tables of the measured values, graphics dependences and evaluation of the concrete metering. The metering deals with the influence of the amplitude of the screened signal, phasic error, suppression carrier, amplitude imbalance, convolution code, guard interval and with the using the several modulations on a bit error rate BER, modulation error rate MER (S/N), the quality and the level of the received signal for the several TV channels.
Works stress and coping strategies in relations to human immune system
Pospíchal, Martin ; Rymeš, Milan (advisor) ; Šolcová, Iva (referee) ; Letovancová, Eva (referee)
Úvod ABSTRACT Work stress and coping strategies in relation to the state of the human immune system Research in recent decades has shown that not only purely biological factors have an effect on the immune system and the possible development of disease. It is becoming increasingly clear that psychological factors must also be taken into account. The topic of our research is to try to clarify, at least partly, how coping with work and life worries (or mental stress) affects a person's health, mainly the activity of immune system, especially in relation to the possible progression of cancer. In the presented research we focus on three basic research areas, being the possible connection between the experienced number of demanding life and work events and the increased chance for the development of oncological disease. Furthermore, we look to identifying the possible difference in the use of strategies for overcoming stress in sick people and those who do not get sick. In the last part of the research, the possible connection between the experience of cancer and the perceived positive benefits of this challenging life experience. We try to answer these (first two) research areas by comparing the two researched groups: groups of people without cancer and groups of people after cancer treatment and then a...
