Computation of a closed curved beam deformation
Dvořáček, Jan ; Krepl, Ondřej (referee) ; Hrstka, Miroslav (advisor)
Presented bachelor's thesis deals with a computation of a closed curved beam (ring) deformation with a U-shaped cross section. The thesis consists of four parts. In the first part a brief summary of theories used for analytical solution is given. Specifically energy approach and related straight and curved beam theories, Timoshenko beam theory and Euler-Bernoulli beam theory are listed. The second part contains a complete analytical solution of given problem for both straight and curved beam theories. In the third part a design of computation models and numerical solution is described. In the last part, obtained values are compared and reviewed.

Forming device integration into production line
Šabata, Radek ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
ŠABATA Radek: Forming device integration into production line Due to raising need for flexible exhaust hoses made by WESTFALIA Metal s.r.o. is com-ing closer to its manufacturing limits of inner ending rings. Finding suitable layout and technological solution is needed. Inner ring is made from scroll sheet steel 17 240. Sheet is roll bended, WIG welded and formed into final shape. Problem is press PYE 160 which is used for other company needs. Replacement of this press with new machine spe-cialized for this part is solution. Thanks to its specialization it will be smaller. Two main technology variants were considered - radial expanding and thorn expanding. Radial ex-panding is not suitable for this simple ring and forming force is bigger so thorn expanding is recommended.

Utilization of SolidWorks at power electrical engineering
Fazekas, Tamás ; Mikulčík, Aleš (referee) ; Veselka, František (advisor)
The purpose of the bachelor thesis was to became familiar with parametric CAD systems and create a simple model in high power electronics branch. The first part of the project summarizes the most known CAD systems. The second part deals with a specifics software:SolidWorks 2008. Finally, a simple model has been created in Solidworks 2008 from the power electronics branch. It is a model of an electric machine which is suitable for the research of the sliding contact.

Inquiry-based science club for children
Šulcová, Alena ; Čapek Adamec, Martin (advisor) ; Blažková, Veronika (referee)
This Bachelor thesis is dealing with the use of research-oriented teaching during hobbies as part of leisure activities in the field of natural sciences, especially chemistry. Nowadays is noticeable trend to start with research activities and building relation to natural and technical sciences at very young age of students. In the theoretical part the thesis describe principles and forms of research-oriented teaching and their realization, lecturer qualification conditions and work safety during the experiments in the hobby, development of students potential during younger school age, specifics of this students period and characterizes leisure activities in detail and their delineation in relation to formal education. Part of the practical part is a local survey of the accessibility of research-oriented clubs in the Polepy and Libochovice districts. The empirical part contains verified proposals for five meetings of the science-oriented research group for students of younger school age. The preparation allows both: face-to-face and distance form and indicates the availability and price budget of the material, the risks and the safety of working with tools, the clearly stated goal of each meeting and a detailed description of the students research-oriented activities, including questions and...

How the teacher perceives his work as a leisure teacher.
MALČÁKOVÁ, Eva
The diploma thesis focuses on the topic of how a teacher perceives their job as a leisure-time teacher. The main point of the whole thesis is to search for an answer to the following research question: "How teachers who, apart from teaching, lead after-school clubs perceive their work as leisure-time teachers?" The goal of the thesis will be to obtain subjective statements from specific teachers in relation to the research question. The theoretical part characterizes basic terms connected to key philosophical and pedagogical terms from the field of pedagogics. The empirical part is realized by means of qualitative research using in-depth.

After school activity in chemistry education
Provazníková, Eliška ; Teplý, Pavel (advisor) ; Šmejkal, Petr (referee)
This diploma thesis deals with chemistry and science after school clubs, which are held in schools or in official public organization called "leisure education centres". Chemistry after school clubs, play an important role in motivating pupils to further study chemistry, enabling them to carry out more experiments, acquiring practical skills, and applying theoretical knowledge. Last but not least, chemistry after school clubs help pupils to spend their leisure time meaningfully. This thesis is divided into the theoretical and practical part. The theoretical part describes the importance of leisure time, motivation for education legal basis for leisure education and other topics related to chemical interest groups. The practical part contains the results and analysis of the questionnaire survey, which was realized mainly among the chemistry teachers. The results of the survey show that the chemistry clubs are mostly focused on the realization of the experiments and the dissemination of the curriculum. And the pupils themselves are primarily interested in establishing of clubs. Most after school clubs aren't organized in leisure education centre. For this reason, they can't use state funding for the clubs, which are organized in leisure education centre.
