Development of Inverse Tasks Solved by Using the Optimizing Procedures and Large Number of Parallel Threads
Ondroušková, Jana ; Skarolek, Antonín (referee) ; Brestovič, Tomáš (referee) ; Horský, Jaroslav (advisor)
In metallurgy it is important to know a cooling efficiency of a product as well as cooling efficiency of working rolls to maximize the quality of the product and to achieve the long life of working rolls. It is possible to examine this cooling efficiency by heat transfer coefficients and surface temperatures. The surface temperature is hardly measured during the cooling. It is better to compute it together with heat transfer coefficient by inverse heat conduction problem. The computation is not easy and it uses estimated values which are verified by direct heat conduction problem. The time-consuming of this task can be several days or weeks, depends on the complexity of the model. Thus there are tendencies to shorten the computational time. This doctoral thesis considers the possible way of the computing time shortening of inverse heat conduction problem, which is the parallelization of this task and its transfer to a graphic card. It has greater computing power than the central processing unit (CPU). One computer can have more compute devices. That is why the computing time on different types of devices is compared in this thesis. Next this thesis deals with obtaining of surface temperatures for the computation by infrared line scanner and using of inverse heat conduction problem for the computing of the surface temperature and heat transfer coefficient during passing of a test sample under cooling section and cooling by high pressure nozzles.

Reinforced concrete slab supported on columns
Horský, Jan ; Perla, Jan (referee) ; Požár, Michal (advisor)
The Bachelor thesis is aimed at calculating internal forces and assessing the reinforced concrete point-supported slab of the 1st floor of the department store. The moment coefficient method and the software method of the finite element method in the SCIA Engineer were selected for the calculation. The thesis also includes the design and assessment of the column and the foundation pad.

Design and stress analysis of temperature and force sensor in hot rolling process.
Nejedlý, Pavel ; Pohanka, Michal (referee) ; Horský, Jaroslav (advisor)
In the process of hot rolling is roll surface thermo-mechanically stressed. To define lifetime of roll or to increase it by change of thermal mode, temperatures and forces acting on this roll need to be known. For this purpose should be used sensors, that are placed near by surface of roll. Aim of the first part of diploma thesis is to debug 2D computing model (MKP) to achieve the match of temperature graphs with experimentally measured values, which was recorded by temperature sensors in real process of rolling. In the second part the same temperature boundary conditions are applied on 3D model, which is used to solve mechanical strength check of the temperature sensor. The last part of thesis is design and verification of mechanical strength of the designed force sensor. The used boundary conditions were acquired in Laboratory of heat transfer and flow. The computing system ANSYS 11 is used to design a model of geometry and numerical calculation. This diploma thesis will be used as donating solution for the granted project, which started in this year with Laboratory of heat transfer and flow partnership.

Residential building in Prague
Horský, Jan ; Šváb, Miroslav (referee) ; Požár, Michal (advisor)
The final thesis is focused on calculating internal forces and assessement of selected structural elements of apartment building in Prague. The software finite element method was selected for the calculation. Foundation slab and basement walls were assessment as „white tub“. Further was assessment aimed to basement column and ceiling slab of typical storey.

Sports motifs in Bohumil Hrabal's short stories
Horský, Jan ; Špirit, Michael (advisor) ; Holý, Jiří (referee)
This thesis focuses on sports motifs in Bohumil Hrabal's short story collections. Its core is Hrabal's collections Perlička na dně and Pábitelé. The thesis examines the concept of sport in literature, the development and depiction of sport motifs in the Czech literary tradition. It then examines in more detail the sports motifs in the individual texts of both collections, points out the differences in the treatment of sport in Hrabal's work and notes the various contexts and roles that sport plays in Hrabal's stories.

Foreign stays of students from 1st generation of Goll's school
Fapšo, Marek ; Beneš, Zdeněk (advisor) ; Horský, Jan (referee)
This presented work is focused on the topic of so called Goll's School. It pays its attention to the foreign stays of Jaroslav Goll's oldest students (Josef Pekař, Josef Vitezslav Simak, Jaroslav Bidlo and Ladislav Hofman), which are situated to the period of "long 19th century". The point of it was to show some concrete perspectives of examining the term "Goll's School", which does not have to be treated as just a methodological group. The main features are Jaroslav Goll as a charismatic tutor, his organization skills or social net of personal relations. These all eventually put together few historians, who are today known as Goll's School.
