Temperature as Source Sphere of Conceptual Metaphors
Hýsková, Tereza ; Vaňková, Irena (advisor) ; Pacovská, Jasňa (referee)
This thesis is focused on a research of the source domain of temperature and related concepts. It is based on the approaches of American and Polish Cognitive Linguistics. The first part is regarded to the relationship between the concepts of WARMTH / COLD and other basic concepts. The crucial part of the thesis deals with temperature as the source domain in conceptualization of emotions, emotional states and human behaviour. This part includes the description of general phenomenon in the process of mapping from the source domain of temperature to the target domain of emotions. The next chapters are focused on the Czech expressions related to separate emotions which are viewed as the target domains. There are marked the source domains of WARMTH, COLD, HEAT and FIRE in the thesis. These source domains are considered to have different roles and the human corporealness is assumed to be the main reason for the differences.

Impact of temperature and drought on gliadins and glutenins contents in four varieties of wheat
Tomasz, Teresa ; Vítová, Eva (referee) ; Hrstka, Miroslav (advisor)
This diploma thesis deals with an influence of high temperature and water shortage on the protein content of gliadin and glutenin fractions in four varieties of winter wheat: Bohemia, Tobak, Pannonia and var. Syria with designation S46 (IG142780). The crop was grown at 26, 29, 32, 35, 38 and 41 °C during anthesis under control irrigation treatment (with soil moisture higher than 70 %) or under drought stress (with soil moisture lower than 30 %). To separate gliadins, the A-PAGE method was used, and glutenins were separated by SDS-PAGE method. Proteins were quantified by computer densitometry. Significant influence of genotype on the gluten proteins was found. Variety Pannonia has high content of -, 5-gliadins, LMW and HMW glutenins, but low content of other gliadin fractions. It was the opposite in the other varieties. Due to temperature, as well as drought, there was an increase in the content of all gluten fractions, especially of HMW glutenins, 1,2-gliadins and total gliadins. The largest increase in the gluten fractions due to drought was observed in Syria variety. In other varieties simultaneous exposure to drought and heat caused decrease in gliadin content, but increase in glutenin content. Drought at high temperatures reduced gliadin-to-glutenin ratio, mostly in Bohemia variety. This ratio has increased due to the temperature, especially in Tobak variety. For Syria variety, no effect of stress conditions was found on gliadin-to-glutenin ratio.

Calculation of temperature field of the busbar bridge
Měrka, Ivan ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
This term project’s aim is to theoreticaly analyze thermal phenomena and losses in electrical power devices, describe the design and application of UniGear ZS1 type switchgear, put together a computer simulation model for thermal calculations of current and optimized solution and finally to discuss obtained results and compare them with experimentally acquired values. The main objective of this project is to determine, whether simulation is a viable and reliable enough method, that it could replace the costly real life physical testing. Modelling of the progress of thermal processes in different parts of the examined busbar will be done in computer aided design program Solidworks and its simulation plugin Flow Simulation.

Calculation of the distribution of temperature field of induction machine
Suk, Jiří ; Dostál, Lukáš (referee) ; Janda, Marcel (advisor)
The issue of this bachelor’s thesis is calculation of the distribution of temperature field of induction machine. There is used three different methods of calculating which are compared in the conclusion. First method is lab measuring of surface temperature on different spots on the machine while unloaded without active cooling. Temperature is measured on four spots using different devices. Another way how to calculate temperature field is computer simulation in ANSYS Workbench using finite elements method. In this method is necessary to create real-based model of motor in CAD system. In this case Autodesk Inventor 2015 was used. Last method was simplified analytics calculation using heat circuit of the stator part. Last but not least is comparison of all used methods, results and accuracy of calculation.

Affecting the function of thermal release of circuit-breakers for different connection systems
Lednický, Ján ; Vetiška, Vojtěch (referee) ; Dostál, Lukáš (advisor)
Right function of securing electrical installations is one of the most important factors preventing people, animals and electrical devices themselves from being electrocuted. Circuit breakers with an overcurrent tripping unit work with bimetal. When the bimetal is warmed up enough, it causes disconnection of circuit. This prevents people and animals from being harmed. To make overcurrent tripping unit work the right way, we have to minimise unnecessary disfunction factors caused by thermal thaw and Joule´s heat. This thesis is aimed at gaining general knowledge of heat transmission and transition of electrical current into heat. There are going to be made temperature-rise curves using all available connection sets to evaluate the impact of each one on the tripping unit. Then, a temperature profile of the circuit breaker will be made using a simulation made using SoildWorks Flow Simulation program. Finally, critical places of the current path will be observed.

System level analysis of thermal properties of integrated circuits
Vaněk, Martin ; Jirák, Josef (referee) ; Frk, Martin (advisor)
Hlavním cílem této práce je shrnout základní poznatky o tématech spojených s teplem, se zaměřením na aplikace v elektrotechnice, a provést měření tepelného odporu pouzder integrovaných obvodů. První část je praktická a zabývá se teorií přenosu tepla, tepelnými vlastnostmi materiálů a metodologií JEDEC pro měření tepelných vlastností pouzder integrovaných obvodů. Druhá část se skládá ze sestrojení teplotní komory s přirozeným prouděním, návrhu testovacích desek plošných spojů a tepelných měření. Na závěr je shrnuta metodologie pro měření tepelného odporu čip-okolí spolu s uvedením praktických poznatků z předchozích měření. Tato práce může sloužit jako základ pro další vyhodnocování tepelných vlastností integrovaných obvodů a pro ověřování přesnosti tepelných simulací. Také může pomoci při vyhodnocování tepelné vodivosti desek plošných spojů.

Calculation of temperature fields in induction machines
Horálek, Lukáš ; Dostál, Lukáš (referee) ; Janda, Marcel (advisor)
The issue of this thesis deals with the thermals electrical machines. Specifically, the calculation of temperature fields using the finite element method and analytical calculation of one of the machines with a replacement thermal circuit. Using Autodesk Inventor create a 3D model of the real electric machine and then in the ANSYS Workbench perform thermal analysis using finite element method. Next, perform analytical calculation of one part of the machine, namely the stator, using a simplified thermal replacement scheme. Also, we realize the measurement of temperature on the specific machine under various operating conditions, the calculations and measurements between them compared.
