Optimization of a sinusoidal pump
Sluše, Jan ; Bílek, Martin (referee) ; Pochylý, František (advisor)
The aim of the diploma thesis is to design the technical solution of minimization of frictional losses, which occur when using a sine pump at position of the shaft locking and on the impeller wheel. The losses originating from the frictional forces have a negative influence on the lifetime of individual parts and economy of the pump. In the first part the author describes sine pumps from the constructional point of view and the main producers are mentioned. The second part contains suggestions on the parameters of the pump and various possibilities of solutions. The last part covers the experiment and conclusions.

Goniometric functions in physical applications
Hanzlík, František ; Kvasz, Ladislav (advisor) ; Mošna, František (referee)
This Bachelor thesis gradually presents the properties of goniometric functions as part of physical phenomena which really exist and which people make use of. The phenomena are introduced in four separate chapters named after the experiments which are their central theme. The first chapter describes the movement of the body along the inclined plane. There is shown how we can use such movement to find separate points which lie on the tangent function. However, since all four basic goniometric functions can be expressed by just one function, for example the cosine function, of which the graph is a sinusoid, all next chapters deal with the sinusoid. For the first time it is plotted in the second chapter where are demonstrated some rules of the movement of the harmonic oscillator over time. In this thesis, important sinusoid transformations are also indicated. There is shown that the graphs of sinus and cosine functions differ only in their displacement. Thereby are those functions interlinked to each other. In the third part, when describing the effects of centrifugal acceleration on bodied located on Earth, some other features of the cosine functions are given, making use of the fact that the size of the centrifugal acceleration depends on the cosine of the angle which indicates the latitude. In that...

East and West and Cognition
Koláček, Luboš
of rigorous work Mgr. Luboš Koláček, Ph. D. The work is a specific approximation of the European author to the thought of the West with the East, based on the thinkers he selected on both sides. It presents a reflection of ontological, epistemological, ethical and psychological, sociological and other questions and answers to the problem, indicated by the name itself. It is a kaleidoscopic thinking that, by multiplying the contents in the reflections of the others and the others in the third thinkers, intertwines and unfolds into a huge breadth of ideas. In the work, intentionality is contained in the appropriate network of connections, which represents the West as thinking of explicit meanings and the East as thinking of implicit meanings. The point is to present to the reader not only ready-made statements, but the reader is invited by questions to cooperate in uncovering the unconcealed, i.e. aletheia. It is a hermeneutic method that starts from ready-made answers and only then comes to the questions that are at the same time the background from which the answer arose. It is a special dialogical method that does not want to juxtapose ready-made judgments, but requires the reader to go through this challenge as a co-solver of the question that is to come to the difference between the West and the...

East and West and Cognition
Koláček, Luboš ; Hogenová, Anna (advisor) ; Rybák, David (referee) ; Kalábová, Helena (referee)
The work is a philosophical and necessarily also historical-philosophical comparative analysis of mutually corresponding accents of the issue spanning the period from the 8th century BC to the present, with regard to the "axial period" of cultural "miracle" similarly prosperous cultures and philosophies in the relatively severed countries of East and West. It then deals in more detail with some important and fundamental philosophers and spiritual teachers, related scholars or artists of various disciplines, but also lesser-known personalities, based on general inputs into the deepest depths of thought of these thinkers, all in a relatively intuitive connection, because the scope of work does not allow for a more detailed continuous interpretation of such a wide range of issues. In the end, the author emphasizes, philosophically analyzes and evaluates the most pressing issues of contemporary society. The work should primarily show the Way, not lead, but it is up to the reader / researcher to decide how to approach the text. There is always "some" Enlightenment at the end.
