Foret, Zdeněk ; Vašina, Radovan (referee) ; Starý,, Vladimír (referee) ; Svoboda, Milan (referee) ; Švejcar, Jiří (advisor)
Electron microscopy has become an essential component in many scientific fields, in which it contributes to new discoveries. The microscopy itself is continually being developed and the limits, which seemed to be insurmountable, have been overcome. The instruments have become user friendlier and their mobility enables flexible practical use in the field. The subject of this work is the design of a scanning electron microscope, the calculation of a magnetic curcuit of an immersion objective combined with standard lens, the theoretical calculation of a microscope resolution and the design solution of the mechanical parts of the microscope with a sample manipulator. The thesis includes a description of the electron microscopy development summarizing it briefly from the very beginning up to now. It also deals with electron sources, especially the Shottky cathode, which is to be the main object observed by the proposed device. The work also contains a description of the calculation of the microscope resolution as a function of the current density distribution. Another interesting issue included in the theoretical part is the signal detection, a description of several types of detectors and possible signal processing. The solution of the thesis includes a description of the concept of the scanning electron microscope with an explanation of the distribution of combined lens functions. The optical diagram shows the arrangement of the electron optics system and the distibution of pressure in the chamber of the microscope. The theoretical calculation is devoted to the magnetic curcuit design of the objective and to the resolution of the microscope for a given extent of working distances. Two modifications of the lens were designed – a standard simple objective and a combination of the standard objective with the immersion magnetic one. The results of both modifications are given for the parameters to be compared. The combined objective was designed with the possibility of use in two modes, as a standard and immersion lens. The deflection system is also divided into two modes, as a single deflection for the standard lens and as a two-dimension deflection for the immersion lens. Detectors for secondary electrons (SE) and detectors for back scattered electrons (BSE) will be used for the signal detection. The design of the microscope is another large part, which gives details on the most significant components of the microscope. The content of the technical solution is a three-dimensional computer model, created in Autodesk Inventor, which also includes a sample manipulator driven by piezoelectric actuators.

Fire station with gym
Svoboda, Martin ; Machová, Petra (referee) ; Vajkay, František (advisor)
The aim of the work is to design Fire station with a gym in Olomouc. Diploma thesis has three parts. First from institute of building structures, second from intitute of building services and last part is devoted to modeling and assessment of details of building. Fire station is divided into three parts. Garage for 3 fire trucks, main part and gym with training tower. The main part contains toilets, showers, locker rooms, storage places, offices and facilities for firefighters and office rooms. Structural elements of the building are from reinforced concrete. Infill walls are made from ceramic bloks. Thermal insulation is from mineral wool and cladding of the wall is made of fibre-cement boards. The slab in the main part is made of cast-in-place concrete. Others slabs in the garage and gym are made of prefabricated elements. On the building are desined three types of roofs. Extensive green roof, flat roof with a stabilization layer of river aggregates and roof made of insulating sandwich panels. In the thesis is design conception of artificial lighting, ventilating, heating, cooling, water managment, photovoltaics and management scheme of energy and ecological systems. The work contains project documentation for building permits, which were made in accordance with applicable legal and technical regulations.

Pozitive and negative selection of mitochondrial genome
Svoboda, Matěj ; Kupková, Kristýna (referee) ; Maděránková, Denisa (advisor)
The bachelor thesis engages with problematics of positive and negative selection of mitochondrial genome. Thesis is divided into two parts. First part grapples with theory and explanation of fundamental definitions, in particular understates mitochondrial genome, nucleotide mutation, positive and negative selection and furthermore evolution models. Second part focuses on processing mitochondrial DNA practically and on establishing functions in programming environment R. The emphasis is foremost on gene sequencing alignment and exploring substitutions. Consequently, obtained outcomes are contrasted with PAML and KaKs Calculator programme outcomes.

Detached house with graphics centre in Jihlava
Svoboda, Marek ; Uhrinec, Marek (referee) ; Štěpánek, Ladislav (advisor)
The subject of this bachelor thesis is the design of a multi-storey, multifunctional, duplex house with a graphics centre, located in Jihlava. The house is intended for housing two families of four. The operation of the graphics centre will be provided by the residents. The main entrances to the building are oriented to the north. The house has an irregular floor plan and is covered by two mono-pitched roofs. Residential rooms are oriented to the southwest. The building is constructed of ceramic blocks, where the vertical load-bearing structure consists of Heluz masonry and the horizontal structure consists of prestressed Spiroll ceiling panels. The project was developed through the educational version of the computer program AutoCAD. This thesis was created with an emphasis on correct layout, architectural design, static requirements and the fulfillment of structural safety requirements.
