Krystalizačně-strukturní studie bakteriofágového lysinu ECD7
REINDLOVÁ, Žaneta
This bachelor thesis is focused on the crystallization of newly acquired bacteriophage lysine ECD7. Bacteriophage lysine ECD7 could be one of a new alternative class of antibacterial agents possibly used against infectious diseases. The main goal of this work was to manage the basic crystallization methods, then apply them for crystallization of ECD7 lysine and produce a suitable crystals for X-ray diffraction analysis. Data from X-ray diffraction analysis will help clarify the structure and function of ECD7 lysine.

New synagogue in Trutnov
Vašička, Jakub ; Benedek, Borislav (referee) ; Dulenčín, Juraj (advisor)
Diploma thesis theme is design of a new synagogue in the city of Trutnov on a memorial site of the original unpreserved synagogue. Part of the construction program is the creation of a complex used by the Jewish religious community and its members, containing a building for the Jewish community (administrative and educational use), kosher restaurants with use for the general public, and the Museum of Jewish Culture. The aim of the design is to create a set of buildings functioning as a whole respecting the natural landmark of the surroundings and the historical significance referring to the past. The new synagogue is designed as the dominant feature of the whole complex in the place of the original Jewish prayer house and emphasizes the monumentality of the place connected with nature. Other facilities are located in front of the synagogue and create a new public space for locals but also visitors to the city from a wide area not only for spiritual use but also for cultural, social, and recreational.

Structure analysis of molecular crystals
Janíček, Jakub ; Císařová, Ivana (advisor) ; Vojtíšek, Pavel (referee)
Summary: Diploma thesis covers characterization of molecular crystals by X-ray structural analysis. N-carbamimidazoylisonikotinamid and 1-phenylguanidin were chosen, because their potential use in second harmony generation. Their salts with inorganic acids were prepared and determined their structures. Phase transition of 4,6-diaminopyrimidinium nitrate was studied by x-ray diffraction and differential scanning calorimetry. This phase transition is accompanied by thermosalient effect, causing that the crystals jump. Keywords: thermosalient, jumping crystal, X-ray diffraction, non-linear optics, N-carbamimidazoylnikotinamid, 1-phenylguanidin, 4,6diaminopyrmidin.

TOWNHOUSE ON THE WATERFRONT IN PŘEROV
Srpková, Barbora ; Mutina, Petr (referee) ; Jura, Pavel (advisor)
The key role in the project were a light conditions of the given site. These generated a basic shape solution. Futhermore, the building is designed to fit in well together with neighbouring buildings and in order to minimalize shadow cast. In the ground floor are a public-service spaces. In higher floor are spaces for living and in the two top floors are a spaces for maisonnettes.

TOWNHOUSE ON THE WATERFRONT IN PŘEROV
Dvořáková, Kateřina ; Hoffmann, David (referee) ; Kratochvíl, Jan (advisor)
Our development area comprises the corner part of building block delimited by streets Brabansko – Malá Dlážka on parcels No. 4382, 4379, 4378, 4380. The place is divided by the river Bečva and by the waterfront road from the historic town centre. Multifunctional building includes public service and housing. The front entry is from the riverside street Brabansko, parking and supply place on the courtyard open to the street Malá Dlážka. First 3 floors serves as a commercial lease place, which can be free divided due to used space structure. 3th – 5th floor are destined for flats 2+kitchen and 3kitchen, 6th – 9th floor flats 4+kitchen. Urbanistic situation: fractionalism of sporadic building, breach of the street lines, absence of the regulative plan, specificity of waterfront. Space solution: Main feature: calm space with pedestrian, the river – impression – change of mood all day, water reflex, the south sun There are two differential points of view: over the river: sensation context of 2 adjoining building – linearity, pacific mass; close view – expression variety of surrounding allows more creative concept. The mass is connected to adjoining building and grows up. The form is inspired by ship, the corner symbolizes keel. The corner tower was cut in 2 directions, cuts are not so expressive over the river, it is apparent from side and close view. The cut features fallacy - disturbance of the vertical lines turns beholder´s head, it seems to be thinner than the prism. Open corner gives view angle from the rear street and there is a entry place with entry to the grand floor, to stairs to 1st and 2nd floor and through the passage way to car lifts and central stairs leading from basement garage through all the residential tower. There is used attractive views – terrace in 2nd floor for offices and large glass surfaces in flats. The facade raster against river matches scale of adjoining building, raster of cut surfaces is denser. It is the second fallacy – softer scale, so the surface seems to be deeper from the front view. Color solution result from water reflex, there are 3 materials of the diverse reflection intensity: glass, safety enamel dark grey glass and aluminum siding of blue metallic reflex. So there are various surface features all day. There is replaced dark glass surfaces by photovoltaic panels in the various solution. The construction combines concrete frame and wall system, both monolithic steel concrete, the basement is from rigid water-proof concrete construction, which results water and earth pressure. Yard facade is plaster and lightweight facade systems on front face – steel jambs clipped on steel concrete flooring plate. Parking for non-residential spaces is provided by vertical independent car lift for 2 cars and 2 standing for disabled, 36 places in sum. 14 parking standing is in the basement for residential, enterable from yard lift.

Laboratory device involving the high selectivity filters
Tuhý, Luboš ; Kovář, Jan (referee) ; Petržela, Jiří (advisor)
This project deals with the frequency filters of high selectivity. The area frequency filtering is fairly comprehensive and theoretically demanding discipline. The aim of this work isn’t to describe in detail and to include knowledge of the frequency filters, but only to clarify the aforementioned issues. In particular, we focus practically on filters working on other physical principles, especially on the crystal structure of partition filters and ceramic filters. The circuit simulation programs through classes Spice will be one of the parts of the theoretical analysis. There will be presented various options for implementing these filters, and the test products used in the design. The laboratory exercises dealing with frequency filtering and measuring engineered product will be made and based on the theoretical findings of this work. The laboratory exercises will include the developing of the model protocol.

Module for verification of rotational position sensors
Krolák, David ; Růžek, Václav (referee) ; Dřínovský, Jiří (advisor)
This master‘s thesis deals with design and realisation of a control module for automated measurements of the modern contactless inductive position sensors by a mechanical rotational system consisting of a DC motor and an incremental quadrature encoder. The thesis presents methods of driving DC motor and recording of measured data by a microcontroller. The thesis presents a communication protocol between the control module and personal computer via USB interface. A part of this thesis is also to develop a control software and firmware, including the measurement and evaluation of properties of the control module.

Estimation of equivalent circuit parameters of a piezoelectric resonator
Ryšavý, Lukáš ; Majzner, Jiří (referee) ; Sedlák, Petr (advisor)
In this thesis, a simple measurement setup including control software is designed to estimate the parameters of Mason electrical equivalent circuit for piezoelectric resonators. Direct measurements can evaluate variables, such as mechanical quality factor, parallel resonance, serial resonance and serial resistance. These variables are used to estimate remaining parameters. The software is implemented in C++ Builder. Experimental study and verification were carried out on several quartz crystal and piezoceramic samples. The measurements are in good agreement with simulations as it is illustrated by a low value of relative error. The measurement setup will be used for scientific purposes of Dept. of physics FEEC BUT.
