System analysis of braking truck - trailer combination
Haring, Andrej ; Kubjatko,, Tibor (referee) ; Řehák,, Miloslav (referee) ; Semela, Marek (advisor)
The dissertation deals with the issue of braking of articulated vehicles, especially articulated vehicles consisting of a tractor and a semi-trailer. This configuration was chosen with regard to the number of accidents and their consequences, and often also does not suit the technical condition of the tractor and semi-trailer, which is closely related to the safety of operation of these combinations. In the case of road accidents, the consequences are often very serious, whether it is personal injury or material damage. Investigating these accidents is a relatively demanding process, requiring a high degree of expertise as well as the necessary technical equipment. In contrast to these requirements, the availability of sources from which the necessary information can be drawn is relatively low. The available resources are mostly in a foreign language and are usually solutions to partial problems, not systemically comprehensive literature. Therefore, it is possible to say a "constant demand" for the available professional literature dealing with issues related to the solution of traffic accidents not only of combinations of vehicles, but of commercial vehicles as a whole. From the point of view of the importance, or topicality of needs arising from expert practice, the dissertation is thematically focused on braking of combinations of vehicles. There are several key reasons to focus on articulated vehicles. First of all, this is due to the specific character of the vehicle itself, which consists of two communication-linked brake systems. Other reasons are that the information contained in the dissertation, whether it is descriptive information, assessment of the technical condition of the systems, or the measurement results themselves, can be partially or even fully used for stand-alone towing vehicles or trailers. However, not all problems related to this issue can be solved within the dissertation. Therefore, in the dissertation, significant influences are selected, the solution of which, given the frequency and severity, the author considers essential. From the title of the dissertation it follows that this is a system analysis of the braking of combinations of vehicles. The system concept of solving a problem situation and selected problems are a guarantee that really essential parameters are selected within the content possibilities and scope of the dissertation and the system approach to their solution allows a "general" application in solving similar problems. The aim of the dissertation is a system analysis of the influence of selected parameters on the overall braking effect and stability of commercial vehicle combinations, analysis of input parameters on the decision logic of electronic brake system control unit, where procedures but also conclusions can be applied in similar cases with similar input parameters and decision criteria. Another partial goal is to develop a framework methodology for determining the technical condition of individual components of brake systems of commercial vehicles, which will be possible to apply especially in trucks, where electronically controlled systems are installed. Here, too, a systemic concept is applied, which will enable a wider use of this methodology.

Survey and Diagnostics of Reinforced Concrete Structure
Blaha, Jaroslav ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The subject of this master’s thesis is the diagnostic survey of the industry cast-in-place hall. The thesis contains theoretical and practical part. The theoretical part is focused on available options of diagnostic methods and options of materials evaluation. The practical part contains material assessment of chosen elements of construction. This part of thesis is focused on localizing the position and the diameter of reinforcement in every single element. Next step is focused on the quality of the concrete, particularly compressive strength and modulus of elasticity. The modern machines, like Hilti PS 1000 and Profometer PM-630, are used to localize the position and diameter of reinforcement. The quality of concrete is determined by removed bore core. Evaluation of material characteristics of the structure is in the conclusion.

Highway bridge diagnostics
Křepelka, Jan ; Suza, Igor (referee) ; Cikrle, Petr (advisor)
This thesis deals with the inspection and construction-technical survey of the highway bridges D2-058..1 and D2-058..2. These structures ale located on the border with the Slovak Republic and were built in 1980. The thesis is focused on the substructure of this long overpass, because of its major failures caused by leaking water. Theoretical part contains information about construction-technical surveys of the bridges, bridges inspections and theory of ultrasound methods. That method has been used in the practical part for identification of the damage extent. Also, material property have been verified and overall condition of the substructure has been evaluated.
