The design of Audio Amplifier
Schenk, David ; Bohrn, Marek (referee) ; Šteffan, Pavel (advisor)
The theme of my bachelor’s thesis is a design of audio amplifier for the reproduction signal from electric guitars. I decided to combine the advantages of tube preamp with the advantages of digital amplifiers. The work describesthe principle activity of selected involvement, includes the anode voltage filter simulation, analysis and measurement of input and output parameters and thein evaluation. Technical documentation for realization of the amplifier contains printed circuit board.

Optimization of the printed circuit board for power LED
Schenk, David ; Klíma, Martin (referee) ; Ing. Josef Vochyán, Ph.D., ALCZ Jihlava (advisor)
This diploma thesis deals with the problems of heat transfer on printed circuit boards. The first part consists of a theoretical analysis of the principles of conduction of heat in different environments, comparing the properties of common type’s base materials for PCBs in terms of thermal properties and focuses on heat transfer from the chip. In the following part they are general information about the program ANSYS ® Workbench ™. Next part consists of the basic designs of PCBs and their improving. PCBs thermal properties for different configurations are verified with calculations, simulations and practical measurements. In the last part there are created design recommendations for PCBs design based on the comparison of the results of initial proposals and proposals to improvements.

"The wealth of nothingness" - On the (im)possibility of metaphysics in Adorno and Beckett
Schenk, Jan David ; Hartung, Gerald (advisor) ; Sepp, Hans Rainer (referee)
English abstract: "The wealth of nothingness - On the (im)possibility of metaphysics in Adorno and Beckett": The subject of this paper is Theodor W. Adorno's reception of Samuel Beckett and its embedding in his philosophy. Based on an interpretation of Adorno's treatment of the problem of temporality, it is shown that for Adorno Beckett's work both marks the end of time in a bad infinity and at the same time prepares the turn into a fulfilled time. As the opening of a quasi- utopian temporality, it is argued that the engagement with Beckett represents for Adorno as much as the rescue of the possibility of metaphysics and critical theory through its impossibility, moving in the semantics of gift, promise, and gratitude. Keywords: dialectics, temporality, metaphysics, gift, utopia
