Electrical and electronic device insulation systems experience multiple stresses while in service. Insulation design engineers usually make attempts to study the behavior of insulation under multiple stresses to keep the size and weight of the electrical insulation at a minimum. In this thesis, magnet wire insulation properties under multiple stresses are studied. Magnet wires are used for insulation in transformers, flyback transformers, solenoids, sensors, motors, adjustable speed drives etc. The magnet wire insulation under study in this work is micrometers thick, yet they are expected to provide high breakdown strength, good windability, and resistance to moisture. Accelerated life tests are performed on two different AWG 43 magnet wires. Combined Weibull Electrical-Thermal life models and Electrical-Thermal-Frequency life models were successfully verified in this work. The statistical information like lifetime characteristics, probability of failures, and lifetime percentiles determined for the two different magnet wire insulation is helpful for a better understanding of their insulation properties.

This diploma thesis deals with the problem of satisfying needs of preschool age children in preschool facilities. The theoretical part of this work provides an insight into the curricular reform in the Czech Republic and a view of perception of children needs by the society. Furthermore there is has been research into the contemporary trend of coordinating a family life with an employment. This was one of the reasons for founding of business kindergartners. A summarization of current legal conditions of establishing of business kindergartners is included as well. Furthermore, the theoretical part includes a relation of curricula documents and satisfying children needs in the kindergarten. Important sections of this work are summaries of various models of needs and list of means of satisfying the needs in the kindergarten. The aim of the practical part of this thesis is to do a qualitative survey in differences between business and state kindergartens in satisfying needs of children. The result of the survey show that are differences in surroundings created in order to satisfy children needs while approaches for the satisfying of children needs were similar.

This work deals with the influence of multistress ageing (electrical and thermal stress) to relaxation effects depending on defined conditions had being labored.

(in English): The aim of this thesis is to present the personality of Anne of Silesia at several levels: as king's daughter, wife, mother, duchess, foundress and candidate to holiness. The initial part sums up the phenomenon of female sanctity in the 13th century influenced both by new religious orders and by the ideal of "holy ruler" pursued by Anne of Silesia as well. The biographical chapter that follows deals especially with Anne's activities as the duchess of Silesia and benefactress of ecclesiastical institutions. It is based on extraordinarily rich diplomatic material. Though Anne of Silesia did not reach official canonization, a Latin legend on her survived which testifies that a certain religious veneration of her existed. The final part of the thesis studies the legend using the comparative analysis method, that is comparing Anne's legend with those of her more famous predecessors and relatives, Elizabeth of Thuringia, Hedwig of Silesia and Agnes of Bohemia. The thesis concludes that the position of Anne of Silesia after her husband's death was extraordinarily strong for the given period, and formulates the hypothesis that Anne may have held the land in indivisible ownership with her son. It is impossible to find an unequivocal answer to the question why Anne did not reach official...
