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.

Controlling of camera
Tylš, Ladislav ; Valach, Soběslav (referee) ; Richter, Miloslav (advisor)
This thesis describes the principles of making application which is able to set and control camera. The first part describes basic camera connections and it explains definition and specification of camera’s features. The second part of my thesis describes implementation of application, which can use more cameras to image preview, image acquisition and to simply set of camera’s features. To implement the applications we can use MATLAB and C++BUILDER uses opencv libraries.

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.

In the process
Volková, Markéta ; Velická, Erika (referee) ; Korbička, Pavel (advisor)
My bachelor's thesis is an object responding to the space that surrounds it. It points out the contradiction between organic and austere form. In my work, I materialize abstract experiences through metonymically selected building elements related to the places in which I have these experiences. As an extraction of elements appearing in the architecture of the Southern Mediterranean, a form of ornament appears in the work, which is understood by a figurative comparison to the experience of travelling on holiday. Another element, representing a figurative experience of returning "to reality", are the lux spheres. Their character is linked to the architecture of Central Europe. I explore the relationship between the different types of buildings, which I then freely develop. My perception of reality enhances the recognition of the new with the already known. I let the objects represent and capture these two opposing perceptions with implications and emphasis on their differences. In this way, I come to find in my work a similarity between geometric austerity, which signifies perfectionism, and the intuitive unfolding of ornament, which inserts the theme of organicity into the object. An important aspect of the thesis is processuality. I understand my work as a border between conceptual and intuitive process.
