Memories
Conde, Tamara ; Schubert,, Theres (referee) ; Malý, Břetislav (advisor)
In this work I reflect on the obsessive compulsive tendency of materializing fleeting thoughts and moments. I use leaves and their placement and detachment from landscapes as a metaphor to memories, through an installation with video.

Design of Experimental Stand for the Study of Railway Vehicles Sanding
Galas, Radovan ; Hruška, Marek (referee) ; Šperka, Petr (advisor)
Presented master’s thesis describes the design and the implementation of an experimental device used for the study of tribological aspects of wheel-rail contact. In this work, the reader will first learn the fundamentals such as adhesion, slip, traction curve, etc. Subsequently, the work is describing devices that are used for the study of wheel-rail contact around the world. This section is followed by the author proposed solution. The result is a twin disc device in the scale of 1:3. The device allows determining traction characteristics for different environmental conditions (presence of water, sand and oil in contact for different temperatures) and various operating parameters (contact pressure and speed). A part of this work are also the validation experiments and complete design documentation.

Belt conveyor
Konečný, Tomáš ; Pokorný, Přemysl (referee) ; Řezníček, Milan (advisor)
The aim of this bachelor's thesis is to propose design solutions conveyor belt to transport sand and gravel to concrete batch mixer. The maximum transport capacity 2000 kg/cycle, the cycle time benefits, including stirring for 4 min and 4.5 m height difference work contains a description of the main functional parts of the conveyor belt, functional calculations according to standard ISO 5048, determination of main dimensions, the design of the drive and tensioning devices. Strength calculation is performed for tightening screws, nuts and truss structures.

Revitalization Program of Floral Garden in Kromeriz
Guzdek, Adam ; Šupler, Libor (referee) ; Jura, Pavel (advisor)
Today's entrance through honorable courtyard is so representative that there's no sense of replacing it by a new one anywhere else. The entrance object has a triangular tympanum including Maxmilian Josef's gold signature and coat of arms. It looks like noble city palace of that period. Sense of the first floor, so called piano nobile, is slightly recognizing on a facade. It's the floor with a larger high that's intended for representation. Therefore I decided to use the historical object fully and all the visitors' equipment, exhibition and lecture spaces are placed right here. New-buildings in the garden are minimized that way. I conceived both of the resolving gardens very sparingly. The reason is their historical essence. Always they were only related to the formal part of the Flower garden. Premises used for any purpose (breeding of rare birds, resource for rabbit hill, growing tulips and oranges). Květnice with the cut lane walls to allow the visitor facilities and provide some exciting long-distance views Converging walls, disorientation in space, entertainment in the bowling alley, in the maze. These elements should remain a formal part of the garden today. They should be isolated and without competition. I design gardens with order, as well as the designed Libosad itself.

Hydrodynamic mixing of water-ask mixture in vessel
Holub, Přemysl ; Franc, Zdeněk (referee) ; Habán, Vladimír (advisor)
Master´s thesis Hydrodynamic mixing of water-ash mixture in vessel is interested in describing fluid and solid particles flow in a vessel. The mixing was conducted in cylindrical vessel by a radial nozzle. The goal of the thesis is to describe flow field and places where the most of the particles are descending according to position, depth, flow rate and nozzle orientation in the vessel. An experiment was conducted in order to investigate and document 8 different positions and orientation of the nozzle. Significant changes in flow fields and mixing time were observed. A mathematical model of the vessel with the nozzle was created in Fluent program. Places with the lowest velocities according to the model were in good agreement with places where the most of the solid particles were descending.

Design of rail vehicle sanding systems
Balounová, Hana ; Šperka, Petr (referee) ; Hartl, Martin (advisor)
The bachelor thesis deals with creating an overview of sanding systems, which are available on the marketplace in terms of their construction. Sanding devices are used in rail transport to incerase the adhesion during braking and moving off in bad weather condition. The thesis inculdes findings of testing influences of construction on the quality of sanding, list of companies producing sanders and their products and defining the future development trends.

New pavilion SOU Písek
Troup, Tomáš ; Klubalová, Pavlína (referee) ; Bečkovská, Tereza (advisor)
Diploma thesis deals a project documentation of a new school pavilion SOU in the location Pisek because of the unsatisfactory existing school bulding, which is located at a small distance from the new pavilion. Investor wants to build a new object of universal classrooms for ca. 180 students and sports hall with hygienic and technical facilities, which will be able for football club FC Pisek (football fields and central object of FC Pisek are close to neighboring plots). Investor wants to let the school canteen be on the current place, which is north of the new object. The object is designed as a two-floor with roof ascent (3.NP terrace), part of the building is embedded in the ground. The structural system of the school object is a ceramic bricks system, structural system of the sports hall is a reinforced concrete system. The roof of school object is warm flat roof and roof of sport hall is warm flat roof as well but mono-pitched type. The object has a U -shaped.

Possibilities of enhancement of kaolin whiteness
Krahulová, Veronika ; Bartoníčková, Eva (referee) ; Opravil, Tomáš (advisor)
This thesis focuses on problematics of increasing the kaolin whiteness index. The aim of the thesis is to verify possibilities and efficiency of the mechanical method of increasing whiteness of kaolin using sand of a defined fraction. This method cannot be considered as a whitening operation of kaolin but as a pre-treatment of the raw material or as one of the steps in increasing the whiteness. There have been tested diverse proportions of added sand with which the batch of kaolin material was intensively mixed for various times. Moreover, there has been tested influence of water and total batch volume. To characterize prepared samples there have been used several methods; XRF and XRD analysis was used to determine the elemental and phase composition of raw kaolin before and after mechanical sand action. The UV - VIS method with reflectance was used to assess the achieved whiteness.
