City Library, Lausanne
Klinkovský, Lukáš ; Sedlák, Jaroslav (referee) ; Koleček, Ivan (advisor)
The subject of my diploma project is urbanism and architectural design of the city Library in Lausanne, specifically in previous industry area Séveline. Four long line of houses brought easy concept that complete actual structure whole Séveline. Two houses, a shopping center in south part in contact with the new metro station. The second house in the north part, in which se located the new cultural center – the city library. The street between houses will be transformed into urban street that will be mainly for pedestrians or necessary supplies. The library is designed as a single house. It is a five storey building (one ground floor) with dimensions of 98 x 27 m. Mass of the library is cut through a large entrance hall and long skylight that brings light to the library. The main communication connections are escalators in two directions. In the corners of the building are two concrete cores with an escape staircase, elevators and toilets. In the western part (third and fourth floors) of the house is space over two floors.

Traffic accidents on department of forensic medicine – cases from practice
Ďatko, Miroslav ; Zelený, Michal ; Sedlák, Jaroslav
The authors present two cases from the recent practice. In the first case report the authors describe a conflict of an aggressive driver, which occurred after stopping vehicles, one of the drivers was injured and his vehicle was damaged. The second case study concerns the unusual fatal traffic accident, during which a cyclist collide with delivery van. The cyclist was killed at the end of traffic accident due to the fact that the delivery van flipped on the side and fell on the body of the cyclist.

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

Measuring the Deceleration of Trucks up to 12 Tons of Weight with the Use of Engine Braking
Kašparová, Hana ; Sedlák, Jaroslav (referee) ; Bradáč, Albert (advisor)
This thesis deals with braking effect of the truck’s engine. The theoretical part introduces the reader to the basic construction of trucks, describes most using engine and defines the factors having a significant effect on engine braking. In the practical part the reader is familiar with the technique used in making the measurement and description of the vehicle chosen for the implementation of measurement. The result of the practical part is the values obtained by measurement including their interpretation contained in the conclusion.

The Measurement of Car Deceleration During Engine Braking
Bejčková, Jana ; Sedlák, Jaroslav (referee) ; Bradáč, Albert (advisor)
The presented diploma thesis deals with the measurement of car deceleration during engine braking from different starting speeds and different speed gears with a sample of vehicles. This piece of work consists of a theoretical part, where problem background is defined, selected driving parameters including the manner how to measure them are explained and the facts in the field of structural characteristics of the vehicle are given, further from a design of measurement methodology that gives an overall plan of implementation, all the respective information and a description of handling with decelerometer, further from a real measurement of the deceleration including an interpretation of partial obtained values and finally from the evaluation of all results with appropriate conclusions.

Transformations of Cities in the Post-Socialist Era
Sedlák, Jaroslav
The dissertation thesis explores the transformations and new urban structures of housing estates built in the Socialist era. It focuses namely on the decades of transformation of society after the collapse of the Socialist system, when the influence of Western lifestyles and the geopolitical climate changed the way modern Socialist housing development in the Eastern bloc was perceived.

City Library, Lausanne
Jašek, Jiří ; Sedlák, Jaroslav (referee) ; Koleček, Ivan (advisor)
The main issue when designing libraries of Lausanne was an environment in which the library is located. The city is relatively steeply sloping from the Lac Léman and because they offer interesting views of the lake from many places in the city. In this system, when the views are oriented south toward the lake, is a territory that differs in structure from the rest of the city. The valley in which the river flowed Flon in the 19th century were filled on a flat surface vzikly industrial buildings with rational structure that crossed the railroad.
