Design of bio-incubator for cell culture transport
Machýček, David ; Maňas, Pavel (referee) ; Paloušek, David (advisor)
In a research part, this diploma thesis deals with dividing incubators into groups according to their kind of use. From the groups biological incubators have been chosen to describe their construction, to explain possibilities of doing sampling and temperature and CO2 control. The research part is concluded by an overview of biological transport incubators for a transfer of cell cultures. In the part of the thesis which deals with a new construction solution some variations are suggested. The most suitable variation has been chosen after a structural technological description, and it is further described in a constructional solution. The frame of the incubator is made from aluminium alloy and is controlled by FEM. There are individual structural nodes being explained and visualised step by step in the construction solution. In the end of the construction solving some information about making the construction and prices of all continuing manufacture are stated.

Development and design of a modular battery box.
Rozinek, Josef ; Buday, Vladimír (referee) ; Porteš, Petr (advisor)
Tato práce se zabývá problematikou battery packů. V první části popisuje návrh battery packu z hlediska volby baterií, jejich tvaru, velikosti, typu a konfigurace zapojení. Dále uvádí vliv těchto charakteristik na výkonnost battery packu a jeho spolehlivost. Zabývá se problematikou termálního managementu battery packů a jeho vlivu na životní cyklus baterií. V druhé části se zabývá praktickým návrhem konceptu battery packu pro Lithium-polymerové baterie. Kalorimetricky je zde zjištěno množství produkovaného tepla při vybíjení, které je poté využito v CFD simulaci chlazení článku.

Design of all-terrain vehicle with electric drive
Kučera, Pavel ; Blaťák, Ondřej (referee) ; Porteš, Petr (advisor)
This master's thesis describes the design of All-Terrain Vehicle (ATV) with electric drive. The design is focused on the main parts of the ATV, which are designed with modern trends ATVs. Location of electric drive and batteries in the frame of the ATV is solved for the sport version of the ATV. Steering geometry is designed using the program Adams. For models of main components are created stress analysis in Ansys Workbench. The input is 3D model, which is created in Pro/Engineer. The braking system and wheels are designed for movement and braking of the terrain.

Uninterruptible Power Supply
Mrázek, Petr ; Harabiš, Vratislav (referee) ; Chmelař, Milan (advisor)
The thesis deals with Uninterruptible Power Supply (UPS) and associated problems of backup power in case of unexpected outages of electricity. Start of work is dedicated to limitation of the electricity supplies, as well as their causes and consequences. Furthermore, brief history of UPS and subsequently distinguish between UPS’s architectures. There is also a description of the energy sources such as batteries, flywheels or fuel cells. Part of thesis describes security of electricity supply in health care facilities, including requirements for emergency power. The own design of UPS is described in the end.

Stability of cathode materials for Li-ion accumulators
Janíček, Zdeněk ; Libich, Jiří (referee) ; Sedlaříková, Marie (advisor)
This diploma thesis focuses on study of positive electrode materials for Li-Ion batteries. Our aim are intercalation materials whose are really perspective materials whose are widely used in this case. The theoretical part of my thesis focus on basic study of Li-ion batteries and their parameters. We studied charging and discharging processes. AFM and SEM were used as additional techniques for study LiCoO2 a Li0,975K0,025CoO2. We tested lifetime and stability of electrode as a perspective material for electrode for Li-ion batteries.
