Synthesis of the electronically reconfigurable frequency filters
Michalička, Filip ; Dvořák, Jan (referee) ; Langhammer, Lukáš (advisor)
This diploma thesis deals with design of reconection-less electronically reconfigurable filter structures which have single input and single output using unconventional active elements, which have ability to adjust one of their parameter e.g. gain or transconductance. The first part describes basic parameters of frequency filters, the division of filters by frequency transfer response and used circuit elements, their operational modes, the principle of reconnection-less electronically reconfiguration and the circuit design method MUNV. Second part describes all active elements used in the proposal of filters, their properties and the implementation using existing transistor-level models. The third part contains the design of three reconnection-less electronically reconfigurable filters and the simulations results obtained from simulation programs OrCAD Capture and PSpice. The obtained results were compared with theoretical behaviour. This part also contains results of these analyses: sensitivity, parasitic, Monte Carlo and temperature to determine the behaviour in varied cases.

Thermal analysis of electric machine
Ječmínek, Tomáš ; Ondrůšek, Čestmír (referee) ; Janda, Marcel (advisor)
This masters thesis is focuse for measuring devices of temperature and their usability and accuraci in the event of asynchronous engine in operation. The values from meusuring of engine are used for preparing optimalization of construction. The right proposal of construction is check in numerical program and the results are validation.

Complex strength design of condenser
Denk, Jakub ; Naď, Martin (referee) ; Lošák, Pavel (advisor)
This diploma thesis focuses on strength design of steam condenser. The goal of the thesis is to make strength calculations for the specific operation conditions, introduce possible solutions, provide recommendations and refer to weak points of such calculation procedures. First, thermal-hydraulic design in HTRI software is performed. Strength calculations respect ČSN EN 13445 standard. Strength calculation with imported temperature field is performed in ANSYS Workbench software. In the next step, another strength calculation is realized in Sant´ Ambrogio software. Results are evaluated in conclusion chapter, including recommendations for the possible following work.

Data Analysis of Heatmap of Brno
Kozubek, Jakub ; Hurta, Martin (referee) ; Mrázek, Vojtěch (advisor)
The thesis deals with the analysis of temperature data for the area of the city of Brno. It is focused on the design and verification of hypotheses for warming and cooling parts of the city. The result of the work are methods for statistical testing and for regression analysis implemented in the Python programming language, the results obtained using these methods and their subsequent interpretation in relation to the originally proposed hypotheses.
