Roots of Moravian Urban Structure
Mohelník, Ladislav ; Löw, Jiří (referee) ; Prokeš, Oldřich (referee) ; Hrabec, Josef (referee) ; Koutný, Jan (advisor)
The thesis has been written on the basis of main architectural concepts and their application in real life within a historical context investigation. Main architectural concepts are represented in a harmony of architectural composition that deals with relations among form, structure and space in the unique art work. Genius loci play very important role in the architectural creation - it represents a special and extra-ordinary urban locality and its architectural value in the historical, geographical and cultural context. The origin of Ostravice village within the historical frame concept of Moravia domain is the topic of this thesis. Other historical documents gave information about Bruneswerde as the Brno Castle. That means Brno Castle had to be founded not in Brno (as it has been consid-ered for many years) but it was located in Beskydy at Ostravice. The sacred city – Civitas Dei had been located in Bruneswerde region in early ages as the centre of European culture, education and spiritual life. Civitas Dei – divine Jerusalem in the transcription of St. Augustine's book De civitate Dei – is not only glorification of God and religious fantasy. It is also one of significant clues for recognition of historical architecture. The depiction of unknown settlement from the book of unde-fined origin is a superb testimony about extinct architectural works. They are legible from cadastral maps. Brno Castle - residence of nobility and power served shelter to St. Vojtěch, St. Prokop, St. Václav and St. Ludmila as it is obvious for the mentioned picture. Three major temples, three com-position axes symbolized by three towers on coins are in analogical relation to Brno triangle of four saints - the Saint family of Brno temples. Powerful ambitions of Brno City principals and clergy are inscribed into the urban structure in the way of composition relations which are legible to them who devoted themselves to the mystery of harmony. The absence of historical continuity affects personal attitudes and also identity of the whole community. The architecture truly reflects the past state of polis and it is eloquent even after its death. The architectural composition relations influence the natural environment for long time, longer than the architectural work existence. The geometric order of Renaissance Brno existence has not been in attention of architects so far. The features were discovered in characteristic paintings by Albrecht Durer. They are evidently secret works of the genius. A meaningful collaborator and follower in the extensive project was also his friend Jan Čert from Brno and lately from Vienna. His noble genealogy played a significant role in history of Silesia and Moravia for centuries. It is tendency to consider him as Austrian or even German architect. It is because of the fact that the genealogy tree of his noble family had roots in Moravia. It is supposed that Durer with Jan Čert´s support created the extraordinarily monumental architectural and urban works in Brno. A remarkable consensus in the urban composition of two squares and transition of traditional urban structure of Ostravice Civitas Dei into the modern Brno is also confirmed due to the identification of noble creators and owners, who were at the foundation, transformation and extinction of elements of the Moravian urban structure.

Possibilities of simulation modeling of traffic accidents with reduced visibility
Rozsíval, Jan ; Motl, Jakub (referee) ; Bradáč, Albert (advisor)
The diploma thesis deals with the possibilities of simulation modeling with reduced visibility in the Virtual CRASH program, which as the only available programs allows work both with the help of mathematical models to simulate vehicle movement and change parameters to simulate reduced visibility, lighting, etc. The theoretical part contains a description of photometric quantities, deals with the human eye and its ability to see under reduced visibility, a description of the luxmeter meter and luminance analyzers. Here are four main reasons for reduced visibility and their description. It contains a sample of the most used programs used to deal with traffic accidents. The four types of headlights most commonly used in today's vehicles are listed and described. In the experimental part, two measurements were performed. The first measurement to obtain input values to obtain a black and white texture determining the shape of the light rays emanating from the vehicle headlights. The second experiment to obtain the contrasts of the white box, black box and pedestrian for subsequent comparison with the output of the Virtual CRASH program.

EXPERT ANALYSIS OF SELECTED PROBLEMS SEEING PEDESTRIANS BY VEHICLE DRIVER IN VISIBILITY REDUCED BY DARKNESS
Sedlák, Jaroslav ; Kropáč, František (referee) ; Drahotský, Ivo (referee) ; Ptáček, Petr (referee) ; Bradáč, Albert (advisor)
The dissertation is focused on the problematic of the driver´s ability to see pedestrians in the conditions of driving at night. The first part tells the current view of these problematic, terms are defined: the outlook and the range of vision to see the obstacle. This part also describes various effects that are affecting the driver´s ability to see pedestrians while driving at night. Out of all mentioned effects, this project mainly focuses on two parameters – how is the driver´s ability to see a pedestrian affected by his obsolence and developing visual handicap. During the research, high number of respondents of wide range of age and various vision quality were present and attended the experiment. This project proposes a methodology of comparasion of those two parameters mentioned above. The main condition which must have been held was to create absolutelly identical conditions of the experiment used by wide range of respondetns. The best way how to possibly achive the best results is by using a video scene on the PC monitor. Two sets of photographies were made while preparing the experiment (2 various sets of clothes for the pedestrian) and these sets were sorted by using the Microsoft Office Power Point program. This made a simulation of a vehicle approaching a pedestrian at night. The measurement was attended by a large number of respondents who were divided into a total of nine categories, according to age and extent of ocular defects. The dissertation is a methodology for evaluating the measurements, determination of contrast and angular size of the watched object (pedestrian) using the scene on the PC monitor. At the end of the experiment is an evaluation of the measurements and put comments on the results obtained. This project proposses a method for the early detection of the driver´s perception when sighting barriers (pedestrian) using the electrophysiological examination method – the electroretinography (ERG). In this dissertation,the initial measurements were carried out using this method, when during the measurement was unfortunately found that the sensitivity of the method does not allow resolution changes of the electrical potential for so little intense stimuli such as the sight of pedestrians at the edge of the road. But it is not excluded that in the future the further development of the ophthalmological diagnostic method will increase the sensitivity so it will allow to spot the objective moment of registration the obstacle by the viusal organ

Recognition of Weather in an Outdoor Stationary Camera View
Jenčo, Michal ; Juránková, Markéta (referee) ; Herout, Adam (advisor)
This thesis deals with classification of weather from stationary outdoor camera images with a landscape view. It classifies fog, clear, partly cloudy and overcast weather in particular. The problem was solved by computing five image flags and using machine learning. Hit rate of 95% was achieved with only small variances between weather types. The main finding of this work is that it is possible to successfully differentiate between the selected weather types with the chosen set of simple image flags. The implementation of this system enables plotting a graph of weather progression during a chosen day.

Reconstruction of the Janeček mill
Owczarzy, Denis ; Venkrbec, Václav (referee) ; Utíkalová, Ivana (advisor)
The task of this diploma thesis was the development of construction documents for the implementation of project, icluding project specialization. This is a rebuilding of the existing mill and it´s conversion to the object. Proposed reconstruction is solved with a sense of highlighting the exist building and expressing his dominance and function in an environment, where the building is located. From the original state was preserved only main building in historical style, and in contrast to this building were proposed two smaller objects with the background. The object is used as a pension for the accommodation for persons, restaurant and also provides rooms for seminars and meetings. Due to a brooklet flowing in front of the building and location of pension between the spa´s and city parks is the use of this building more than suitable.

Spica/ Brno, Nove sady 49°11'20.3"N 16°36'29.4"E
Šmídová, Anežka ; Kisová, Barbora (referee) ; Nový, Vítězslav (advisor)
Design „micro-urbanism“ in designated area. Aim of this work is to find suitable development strategy of open city block. Bachelor‘s thesis adresses design of poly-functional building in Brno-střed. The main theme was to design a town hall and other more functions as for example living space. Design tries to find optimal solution for site, which is currently occupied by parking lots. The building tries to complete corner of designated city block, which will be part of future „south“ neighbourhood. The townhall and housing should function in harmony, which means the building will „live“ all-day long. Between the site and neighbouring building will be parking garage tucked under the ground between malá Amerika and the designated area. The park will be situated above the parking garage to be open to the public. Building is composed by a pedestal in which town hall is situated. On the pedestal are placed 3 housing clusters. These clusters are designed the way which makes the volumes contrast.
