Measuring temperature inside PC
Rataj, Tomáš ; Kolka, Zdeněk (referee) ; Michálek, Václav (advisor)
This master’s thesis deals with measuring temperature inside personal computer. The main goal of this work is to develop tool which is able to measure temperatures in several places, display a store the values. Theoretical section is concentrated on selection of temperature sensor, that have suitable interface for microcontrollers and has sufficient accuracy for this application. In next part there is complete hardware and software design of instrument. Software solution is based on real-time operating system. Device is projected as a battery-operated compact tool. With created application for personal computer, measured data can be downloaded through USB and displayed in graphic format.

Single span pedestrian bridge
Rataj, Tomáš ; Nečas, Radim (referee) ; Koláček, Jan (advisor)
The subject of the bachelor's thesis is the design of a single-span footbridge. Within the thesis, two variants were proposed and compared, and a simply supported pre-stressed structure was selected. This particular variant was further analyzed and evaluated for ultimate limit state and serviceability limit state. The calculations were performed using the SCIA Engineer and MS Excel software, supplemented with manual calculations. The calculation procedure followed applicable standards and regulations.

Dendrochronologické datování a stavebněhistorické hodnocení krovu kostela sv. Jana Křtitele v Hlučíně
Rataj, Tomáš
The aim of this thesis was to conduct a survey and documentation of construction and the historical development of Object church. John the Baptist in Hlučín, district Opava. The available resources and literature to chart the history of truss structure and determine its typology. Anatomically determine tree species in different parts of the roof structure of the church and using dendrochronological analysis to determine the age of the samples. The work deals with a methodical procedure from dendrochronological sampling, treatment and subsequent measurement until after dating results with comparison using statistical methods within specified Czech and Moravian standard chronologies of tree species. The work is complemented by the resources available on the historical development of building construction. As a result, based on microscopic slides of the samples was identified fir wood. There have been a historical summary of the aspects related to the construction and definition of the age of the individual parts of the roof structure. The truss nave was dated to 1890, the age of the truss presbytery was designed in 1732. Truss above the nave was defined as longitudinally coupled rafter construction Hambálková, stagnant faeces. Historical evaluation of extended documentation package, which is now the object of the church we can leave to future generations. Dating age truss church confirmed the historical development of the subject and contributed to the overall mapping of the now almost restored monument.
