Self-assembled molecular layers on epitaxial graphene
Kovařík, Štěpán ; Švec, Martin (referee) ; Čechal, Jan (advisor)
Samouspořádání organických molekul je spontánní proces tvorby nanostruktur, při kterém je výsledná struktura určena mezimolekulárními and molekulárně-substrátovými interakcemi. Pochopení principů samouspořádávání je klíčem k přípravě funkčních nanostruktur s atomární přesností. Tato diplomová práce se zaměřuje na přípravu a studium samouspořádaných molekulárních struktur 4,4’-diphenyl dikarboxylové kyseliny na povrchu grafenu připraveného na Ir(111). Pro studium vlastností molekulárních struktur je využito rastrovací tunelovací mikroskopie a nízkoenergiové elektronové mikroskopie. Tato kombinace umožňuje získat informace z oblastí o velikosti v řádu nanometrů až milimetrů. V práci je popsána molekulární strukuktura stabilní při pokojové teplotě. Vazebný motiv této struktury je dán interakcí karboxylových skupin sousedních molekul.

HOUSE ON THE EDGE – Valašské Meziříčí, Sokolská Street
Švec, Martin ; Müller, Zdeněk (referee) ; Ruller, Ivan (advisor)
Modern and lightweight-looking architectural concept of the town house, which is the counterbalance to the former historical development and highlight of the look-through axe from the Main square. The inner-space functional allocation come through to the exterior look of the building. The former Poláškova street is extended, there is the piazetta with outside seating. The parter is determined by the roof cantilever and the wooden pergola with the outdoor LED illumination. In the ground floor there are two shopping spaces, pharmacy and film café. The first floor contains rehab centre. Its look is maximally lightweighted, the fassade is made only from the structural glassing. This makes the contrast between the ground floor growing up from the ground a the three-storeyed section for living. This part of building is carried by massive frames from reinforced concrete and is designed as a wood framework with pasted frames and gridiron ceiling pannels. It contains 28 appartments. Most of them are low-cost, epecially for young families and singles. In the underground are three storeys of parking. 81 places are the replacement of former public parking. The arrival ramp is situated on the south side by the Sokolská street. The connection point to the busy drive-through road is on the former crossroad with the Králova street, where are newly installed the traffic lights. The access to the shops is situated on the north side by the historical town centre. To cross the parcel is possible next to the building through the small park on the western side, or throught the centre of the bulding. The terrace above the ground floor is walkable and accessible by the stairs from piazetta or by the skew roof of the film café. The skew roof contains also benches and artificial waterfall, which ends in the fountain. The fountain is there for the good feeling of the space and for technical reasins. It is connected with the reservoir of the rain water.

Fabrication and characterization of two-dimensional heterostructures
Majerová, Irena ; Švec, Martin (referee) ; Procházka, Pavel (advisor)
After the experimental discovery of graphene at the beginning of the 21st century, many other interesting 2D materials have been discovered. However, the electrical and optical properties of these layers are greatly influenced by the composition and quality of the surrounding materials. In order to preserve the exceptional properties of thin films, attention has gradually been drawn to heterostructures from 2D composite materials. This thesis describes the preparation and characterization of heterostructures composed of graphene and hexagonal boron nitride. In addition, a specific focus will be placed on optimizing the production process of heterostructures by the dry thin film transfer process, prepared by micromechanical exfoliation. Characterization and quality of prepared layers are controlled by Raman spectroscopy, while morphology is examined by atomic force microscope (AFM). Furthermore, the electrical properties of the graphene-hBN device are discussed and the charge carrier of the graphene field-effect transistor is measured.

Insurance Fraud
Švec, Martin ; Vykopalová, Hana (referee) ; Štola, Josef (advisor)
The aim of this master's thesis is focusing on the problem of committing insurance frauds in Czech Republic. It is divided into separated chapters. In the introductory part I focused on a theoretical explanation of the terms related to this topic. The following section focuses on explaining the classification and the source of insurance frauds, the reasons of committing these criminal offenses, and the general profile of the perpetrator. Furthermore, in the theoretical part, I outlined the ways of the insurance fraud investigations. The goal of the thesis was to focus on the factors directing to insurance frauds Therefore, the analytic part concentrates on the analysis and the evaluation/assessment of the given statistical data results related to insurance frauds. In the end, for a better understanding, I mentioned a few revealed cases of these criminal offenses, and suggested certain preventive arrangements/actions against their potential happening or their easier revelation (in the future). Finally, I evaluated by analyzing risk groups committing insurance fraud and the main factors that lead to insurance fraud.

Revitalisation of the Hotel Facility by the Brno Artificial Lake
Švec, Martin ; Zemánek, Václav (referee) ; Zemánková, Helena (advisor)
This is the proposal of the new utilization of the former recreational centre, which is situated in the beautiful surrounding of the Brno lake. It has been abandoned for many years and is suffering from decay. It has been built in the 1970's for the demand of the Socialistic youth union (remark: the youth organisation of the communist's party). There were held international political conventions and educational sojourns for the students of high schools and universities. The new utilization will be analogous. Only the communist's ideals will be replaced with the ideals of today's democratical society – especially friendly relations between mankind and environment. There will be created the environmental educational centre with the meeting spaces, conference hall and accomodation. The universal concept enables the usage of the facility also for the international students' workshops, training courses, teambuilding events etc. The ecological educational centre primarily makes the good example and is the live educational requisite. Thanks to the concept of the original facility is very convenient the refurbishment to the standard of the energetically passive building, which consists from the natural materials and utilizes renewable energy resources. Because of the very poor technical condition and devastation of the building will be re-used only basement and steel framework. This solution is more economical than the demolition and following new construction. The construction core of the building is almost for free. However, only if we make minimal changes in the framework and we preserve the original building's shape. On the steel framework will be created the new lightweight housing, which will be made from wood, straw pannels and filled with the cannabis thermal insulation. Almost all the roofs will be covered with the photovoltaic foils and the heat source will be air heat pump. The area is very pleasant place to stay. It's full of sunshine all day long and offers very beautiful view of the lake. The main building and bungalows profit of the attractive views. All the former recreational area has was designed to make the people meeting together and to provide the freedom of move and wide variety of activities. However, the rooms and bungalows provide the highest privacy. The inside and outside of the buildings are shading into each other. All the recreational ground – in exterior and interior – is full of liveliness, in the opposite of the rooms, which are the private islands. This aspect, which is present in the former concept from the 1970's, is to be preserved. The former hotel building is distinguished by the quality architectural concept, above-average in the age of origin. It is thanks to the dynamically balanced composition – inspirative today too, and visually interesting interior design of the meeting spaces. This proposal attempts to continue in this qualities. The ground is enriched with the relaxational spaces and the outside gym path. In the opposite of the original state the area is open to the public and is utilized as a park for leisure activities.
