Water Resources and their Technical Construction
Machač, Tomáš ; Hlaváč,, Jaroslav (referee) ; Kučera, Tomáš (advisor)
Nowdays, the renewal of water supply infrastructure is becoming increasingly hot topic. Gradual renewal is one of the key points for long-term maintenance of quality and trouble-free operation. The most basic element of the entire water supply system are water resources, which shouldn't be neglected during the planning of a renewal. This thesis deals with technical construction of drinking water resources and it is mainly focused on ground-water resources. The main part of the thesis is the design of a technical assessment system for underground drinking water resources for public water supply. The purpose of such system is to create a tool for technical assessment that will identify current technical status of multiple water resources and will compare them. This comparison enables to create more effective renewal plan in future.

The effect of the development of supply parameters on the selling price of houses
Jandásková, Tereza ; Schneiderová Heralová, Renáta (referee) ; Sedláček, Jan (referee) ; Cupal, Martin (advisor)
The dissertation thesis deals with the development of supply parameters, specifically, time on market ("TOM") and the share of the initial asking and selling price IP. In the research carried out as part of this thesis, the asking prices are monitored for the duration of their time on the market until the realization of the transaction as indicators of the market efficiency. As part of the microeconomic research, a database of houses in the district of Brno – venkov is created with 631 completed transactions, where the asking price, selling price, time on market including individual changes in the asking price during the time on market and other relevant characteristics of the individual houses is being tracked. A total of 39 variables were monitored. The primary output of the thesis is the creation of a functional statistical model applicable in microeconomic Czech conditions together with the proposed process model. Another output of the dissertation thesis is the influence of the technical condition on the selling price of houses including defining all significant price-setting factors on the selling price. Statistical tests confirmed the significant influence of the technical condition variables on the selling price. In addition to the recommended values for use in determining the market value price, the work also contains parametric equations for both investigated variables. The first variable examined in more detail was IP, which was examined based on the binary variable "price change" by a logit model. The results point to a primary effect of the time on the market, which, however, is not uniform. The second research variable was TOM, which was examined using a 2SLS model due to its endogenous relationship to selling price. The practical application of the dissertation thesis is in increasing the efficiency and accuracy in estimating the market value of real estate based on the comparative valuation method (SCA - Sales Comparison Approach) in the investigated market segment and selected location. As well as increasing their reviewability and transparency, valuation reports, estimates and expert opinions.

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.
