Automatic Dosing Unit for Pool Chemistry
Kejík, Jan ; Štůsek, Martin (referee) ; Zeman, Kryštof (advisor)
The objective of this thesis was to design and construct the dosing unit for pool chemistry with the features of common available equipments, but with lower acquisition costs compared to these equipments. The initial part of this thesis describes the requirements for water quality in the pools and the principles of its sustaining. The next section describes the ESP32 microcontroller, which was selected because of sufficient computation power and memory resources and RF connectivity capability. Furthermore, the pH, ORP probes and temperature sensors for measurement of the pool water quality are described in this section. Lastly, sensor convertors, power supplies, pump controls circuit and display interface are described here. The key section of the thesis is the design description which consists of hardware, mechanical and software section. It starts by the description of the printed circuit board with a description of diagram. In the section followed is described and illustrated mechanical design of the box for this dosing equipment. It is my own design made by 3D print. The last design section deals with software consisting of three different kinds of software: display software, ESP32 microcontroller firmware written in C/C++ and HTML code of the webside. This description is focused especially on the firmware architecture of the processor ESP32 related to consecutive part including description of a local user interface as well as a web application. The resulting device was developed to the state with matured well tested user interfaces. However, the controls algorithms of pH and ORP were tested only in simulated conditions. Therefore the testing in real pool for verification of the firmware and reliability should be done in the next steps.

Srovnání vybraných sociodemografických ukazatelů ORP Chrudim a ORP Polička
Mutňanská, Nela
The subject of the thesis is the comparison of selected socio-demographic indicators ORP Chrudim and ORP Polička. Demographic comparison is based on the population structure and basic demographic processes. This comparison is complemented by selected social indicators. Comparison of some indicators is not selected ORP, but also in the Czech Republic or the European Union and global trends.

Information for the protection of the population for the citizens of the Týn nad Vltavou ORP on its website
TRÁVNÍČKOVÁ, Marie
The diploma thesis deals with the issues of population protection in the district of Týn nad Vltavou. The aim of this work is to analyse the website of the administrative district of Týn nad Vltavou (as the municipality with extended powers) to protect the population. The partial goal is to find out whether the website provides all necessary for the protection of the population in the emergency planning zone of the Temelín nuclear power plant. The last goal was to survey how citizens use the web pages of the district of Týn nad Vltavou and how they understand them. In order to meet these objectives, an analysis of the Týn nad Vltavou website in the field of population protection and a questionnaire survey of the level of knowledge of the population on this topic is performed. At first we will get acquainted with the area of Týn nad Vltavou. Then we will continue with the current state of protection of the population in our territory and legal norms. The next part mentions the position and tasks of a crisis management worker. An essential part of the work are the tasks of population protection and their characteristics, which are a necessary part of knowledge in this area. Specifically, it concerns the protection of the population at the level of the municipality with extended powers and technical and organizational measures to protect the population, such as, in particular, warning, notification and emergency information of the population; evacuation; hiding; civil defense; civil protection and, as a last resort, general warnings and their importance. An integral part is the knowledge of crisis situations, which are discussed in the work. Following the theoretical part, which is based on a literary search of documents addressing the issue, the work continues with a practical part, which is based on the analysis and comparison of information content in the field of population protection on the website of Týn nad Vltavou. This analysis shows that enough information provided on the website is rated at 85 %. Furthermore, a questionnaire survey was conducted, with the result that most respondents rated the website very positively and also the comprehensibility of information in the field of population protection. The final evaluation of the website providing comprehensible information for the citizens of the Týn nad Vltavou district is evaluated as YES.

Transport accessibility of peripherals areas in the region Vysočina
LEŽÁK, Martin
The main concept of this bachelor thesis is the definition of peripheral municipalities or coherent spatially homogeneous areas in Vysočina region based on comprehensive socio-economic indicators, which describe in detail the various processes occurring in each geographical area. For the author, it was important to use fundamental theoretical basis and detailed work of various social geographers in the this issue to determine the peripherals. In other parts of thesis the author continues by detailed analysis of the socio-economic categories and discovers spatial differences of the analysed region. After the peripheral areas determination, he will present a comprehensive and versatile character analysis of quality of transport service in such municipalities, which is the second aim of this work. Wide variety of activities are bound with the transport accessibility in the geographical area, so it is extremely important to explore its effectiveness, as well as some differences in its quality. Final maps of peripheral areas in Vysočina region and of quality of transport service in these marginalized municipalities are included in this thesis.
