Battery management system for Formula Student
Macko, Maroš ; Bohrn, Marek (referee) ; Šteffan, Pavel (advisor)
This thesis is focused on battery management for Formula Student monopost. Part of the work is the design and implementation of this monitoring system. The system uses a distributed topology, is divided into the main subsystem and subordinate subsystems. The main subsystem and the selection of suitable components are described. Furthermore, subordinate subsystems are designed, and the fundamentals of battery voltage and temperature measurement are explained. Control firmware is implemented and it is able to communicate with the rest of the car. All systems were tested and they comply with the rules of the Formula Student competition.

Formula student battery pack
Lysák, Jakub ; Václavek, Pavel (referee) ; Veselý, Libor (advisor)
The thesis deals with the selection of a suitable battery cell for the high-voltage battery of a Formula Student Electric racing car. Based on laboratory measurements, a mathematical model of the cell is identified. The model implemented on the battery management system is capable of estimating the state of charge under dynamically changing conditions during a race.

Analýza ukazatelů užitkových a funkčních vlastností dojnic po přechodu na robotické dojení
SZMITEK, Daniel
The aim of the diploma thesis was to evaluate the effect of changes in housing and milking technology on the productivity of dairy cows in the Czech Spotted Cattle in the organic farming Farm Otročín in the Karlovy Vary region. Monitoring took place in a commercial dairy farm, where the cows were transferred from the original recon-structed barns with a conventional milking parlor to a new free box barn with milking robots. For the evaluation, records of daily milk yield, visits to milking robots taken by milking robots, records of eating and rumination time detected using transponders with identification on neck collars, which are stored in the relevant SW, were used. Data on the reproduction and treatment of cows were taken from the used zootech-nical records. All data were recorded during the period from 19.12.2023 to 12.3.2023 (12 weeks), when the dairy cows were gradually transferred to a new barn with milk-ing robots.

Porovnání technologií dojicích robotů značky Fullwood
ZUKAL, Martin
The topic of this thesis is: Problematics of Fullwood milking robots. Milk, mammary gland anatomy, milk production and milking are described in the literature review. The overview also deals with the methods of milking, machine milking and automated milking. In the practical part were selected two farms with milking robot Fullwood M2erlin, and were monitored parameters such as the number of milked cows in 24 hours, the number of tumbling and unset milking kit, milking time and daily yield from 1 January 2018 to 31 December 2018. These parameters were subsequently evaluated and analyzed. The results were processed into tables.

Fabrics of the Weinsberg granitoids on example of the Prášily pluton (Moldanubický plutonický komplex)
Pour, Ondřej ; Verner, Kryštof (advisor) ; Racek, Martin (referee)
This bachelor thesis is concerned with the brief introduction to the structures and fabrics in granitoid plutons. In the next part of this work are sumarized results of structural analyses of Weinsberg-type granite intrusion (Prášily pluton) located in the SW part of high-grade rocks of the Moldanubian Zone. This research proceeded based on a combination of field structural data and results of AMS (Anisotropy of magnetic susceptibility) method. The internal fabrics and structures of the Prášily pluton reflect emplacement mechanisms, kinematic history and evolution of the regional strain field during Variscan orogeny at around 330 Ma. The examined area provides crucial constraints for the geodynamic models of geological evolution of deeper parts of the Variscan orogen in the SW part of the Bohemian Massif.

Strain coupling versus decoupling of mantle and crust during orogenesis
Kusbach, Vladimír ; Ulrich, Stanislav (advisor) ; Vanderhaeghe, Olivier (referee) ; Tommasi, Andrea (referee) ; Whitechurch, Hubert (referee)
Deformační interakce mezi horninami na významném rozhraní k·ra - litosférický pláš' je jedním z hlavních proces·, jejichž pochopení umožní lépe popsat termomechanické procesy probíhající hluboko v rozsáhlých pohořích a především chování kontinentálního pláště během kolize kontinentálních desek. Tato disertační práce obsahuje tři hlavní kapitoly, představující výsledky r·zných geologických metod, využitých při zkoumání p·vodu a deformačního chování peridotitových těles ve spodní k·ře Variského orogenu. První kapitola prezentuje závěry ze strukturní studie Mohelenského peridotitu a okolních granulit· z Náměštského granulitového masívu. Jako jedinou efektivní metodou pro studium vnitřní stavby peridotitu se kv·li rozsáhlé serpentinizaci ukázalo měření přednostní mřížkové orientace (EBSD). V serpentinizovaném peridotitu byly zjištěny dva odlišné olivínové skluzné systémy, jejichž distribuce společně s detailním strukturním mapováním v okolním Náměš'ském granulitovém masívu umožnily vysvětlit reologické chování peridotitového tělesa v prostředí kořene orogenu. V této kapiole jsme se pokusili vytvořit geotektonický model, který popisuje historii peridotitového tělesa v rámci mnoha fází tektonické historie orogenního kořenu. Ve druhé kapitole představujeme výsledky z analýzy serpentinizačních proces· v...

Robotizované dojení a jeho působení na dojnice
Ševčík, Jiří
The objective of the dissertation thesis was to evaluate the effects of two different types of milking systems (CMS - conventional milking system vs. AMS - an automatic milking system) on average daily milk yield, on frequency of attending robots, on pre-milking teat preparation procedures and stimulation and milking time, on the teats traumatization of Holstein cows. The experiments were performed in two locations: Žabčice School Farm of Mendel University in Brno and ZEMAX, a. s. in Šitbořice. Data was collected for a period 1st January 2014 to 15th December 2015. Higher average milk yield per day and lower milk yield per milking on the other hand on the farm with AMS were caused by a higher frequency of milking. Cows on farm with CMS were milked twice a day. On the farm with AMS dairy cows were milked in accordance with their own needs. Milking frequency in the AMS was in 2014 2.47, in 2015 2.88 per day. Heat stress has negative impacts on milk production. Effect of heat stress showed more markedly in 2015, which is probably related to the fact that the value of THI greater than 80 lasted longer. The length of pre-milking teat preparation procedures and stimulation various neighborhoods was found in AMS in 2014 from 0:13 min. to 0:16 min., in 2015 from 0:14 min. to 0:19 min. On farm with CMS time not be registered. The length of milking time with CMS in both years was 5:02 min. In AMS was in 2014 from 3:03 minutes to 3:53 min., in 2015 from 3:05 min. to 4:45 minutes. In process of milking machine teat traumatization were smaller when using AMS.

Structural and metamorphic evolution of thermal aureole of the Krkonoše-Jizera Plutonic Complex
Olšanská, Irena ; Verner, Kryštof (advisor) ; Štědrá, Veronika (referee)
Krkonose-Jizera plutonic complex is one of the largest composite plutonic bodies in the Czech massif. The emplacement of this pluton relates to the origin of the structural and thermal aureole. The processes of contact metamorphism are most evident in the northern and southern part. The topic of this work is to find influence of the contact metamorphism in the host rocks. Partial information about contact metamorphism in this area could be found in several papers, but there aren't work which discuss this topic in detail. Goal of this work is to make complex interpretation of contact metamorphic processes connected with intrusion of the Krkonose-Jizera plutonic complex and use this interpretation for discussion about model of magma intrusion. In rocks of contact aureole of Krkonose-Jizera plutonic complex (KJPC) were identified relicts of Variscan regional metamorphism, connected to creation of regional metamorphic fabric S1 and S2. Original mineral associations and deformation fabrics were in near-contact zone of KJPC 1 km in average in width heterogeneously overprinted by effects of the contact metamorphism, which intensity increases towards the intrusive contact. In the mineral associations of contact-metamorphic rocks appears characteristic minerals such as cordierite and andalusite, rarely...
