Power chokes
Škrla, Milan ; Vorel, Pavel (referee) ; Patočka, Miroslav (advisor)
Thesis dissertate power reactors and analyses techniques of an air-core power coils and inductors with ferromagnetic circuit and an air gap. Construction of the inductors verified the accuracy of the calculated values against the measured parameters. According to the outcome of this analysis, corrections of the design process are derived. Thesis design optimization to minimize size, weight, efficiency and in comparsion of these two factoctors.

Blansko Cycle Route - New Castle
Efenberk, Tomáš ; Patočka, Miroslav (referee) ; Kosňovský, Michal (advisor)
The diploma thesis deals with treatment of project documentation of the corridor for pedestrians and bicyclists on road Blansko ČKD – Nový Hrad. It is a common two-way pedestrian and bicycle trail along the Svitava River and railway line No. 260 Brno - Česká Třebová and the regional road II / 379. Part of the design will be any footbridges across the Svitava River and other construction solutions to overcome difficult terrain in the problematic section. Part of the diploma thesis is the concept of a variant directional solution of the route and justification of the selection of a more detailed variant.

Tišnov - transport solutions in the U staré hřbitov locality
Hněvsa, Filip ; Patočka, Miroslav (referee) ; Smělý, Martin (advisor)
The subject of the thesis is the design of traffic zone 30 in the city of Tišnov. The main reason is the layout of the streets Bezručova, Na Hrádku, Svatopluka Čecha, Chodníček, Hřbitovní and the level crossing Svatopluka Čecha. The newly designed local roads are intended to ensure safe driving in this addressed location and to separate the traffic area from the associated one. In this work, 6 variants are proposed, of which only one variant is selected for further elaboration.

Power soldering station 500W
Šelepa, Jan ; Patočka, Miroslav (referee) ; Vorel, Pavel (advisor)
This thesis contains a complete description of the design and implementation of a 500W transformer soldering station. This soldering station includes a half-bridge DC/DC converter with a pulse transformer. The device works with a very low voltage and extremely high output current. Therefore some parts have a special design to ensure the proper equipment function. Coaxial transformer with very low leakage inductance (nH units) is unusual. A synchronous rectifier is another special feature working with low voltage and high output current of the transformer. The finished functional prototype consists of a soldering station and a soldering adapter.

Adjustment an intersection Rerychova x Foltýnova in Brno
Janko, Vojtěch ; Patočka, Miroslav (referee) ; Smělý, Martin (advisor)
The subject of the bachelor thesis is to suggest an adjustment of a local cross intersection in Brno Bystrc. The existing intersection is too vast and obfuscated and does not guarantee safe operation of vehicles and pedestrians. The aim of the thesis is to adjust this vast intersection while maintaining all the standards and regulations and also suggest its mini roundabout version. The traffic volume is calculated based on the obtained camera recording. Then a project part of both version is conducted together with the capacity calculation and the estimated budgets for both proposals.

Modern Mathematical Methods of the Analysis and Synthesis of AC Machines
Cipín, Radoslav ; Skala,, Bohumil (referee) ; Richter, Aleš (referee) ; Patočka, Miroslav (advisor)
The doctoral thesis is divided into three main parts with a focus on induction motors. The first part deals with the electromagnetic design and analysis of windings of AC ma-chines. There is introduced the density of conductors, which describes the distribution of the windings in the slots. There is derived general formula for calculation of the total winding factor applicable to any type of winding. The second part of this work deals with the acceleration method of the induction motors torque-speed characteristics measurement. The measured characteristics are used for exact identification of the equivalent circuit parameters of induction motor. The third section is focused on a very precise identification of the equivalent circuit parameters of induction motor in the form of -circuit. The identification is based on mutual comparison of measured and calculated torque-speed and current-speed characteristics.

The electric precipitator
Broďák, Kamil ; Patočka, Miroslav (referee) ; Huták, Petr (advisor)
The Bachelor’s thesis is focused on the issue of power separation. The first part describes the principle of power separation process. The second part deals mainly with mechanical parts and their function inside the electric precipitator. The third part focuses on the use of electrostatic precipitators and system management. The last section is devoted to design an electric precipitator according to the specified parameters. Due to the dominance of electric separators company ZVVZ-Enven Engineering, Milevsko from the Czech and Slovak Republics, the work focuses primarily on the products offered by their production program.

Lipůvka – turbo roundabout of roads I/43 and II/379
Patočka, Miroslav ; Sedlák, Lubomír (referee) ; Smělý, Martin (advisor)
This thesis builds on previous work on an Institute of Roads FAST VUT dealing with modifications of road I/43 Brno – Svitavy. A conversion of the existing temporary three leg single lane roundabout to egg turbo roundabout with four legs, is proposed there, in accordance with local plan of Lipůvka. The intersection of road I/43 and II/379 can be characterized by large congestions in the morning peak hours during weekdays and afternoon peak hours on Saturday and Sunday. That is the reason for implementation of capacity assessment of designed turbo roundabout and comparison with current situation. Construction of fourth leg is motivated by the planned expansion of residential area and the development of industrial zone on the south-western outskirts of the village and rerouting of the county road II/379 out of built-up area as well. Road I/43 is an important thoroughfare north of Brno, so it is obvious effort to eliminate the bottlenecks on the route. The thesis also includes a theoretical introduction dealing with the design of turbo roundabouts abroad.

Residential Zone village Chválkovice
Rejzek, Jan ; Patočka, Miroslav (referee) ; Smělý, Martin (advisor)
The aim of the bachelor thesis is a design of a residential zone in the village Chvalkovice. New roads, parking places, layout of building plots and engineering network in the street were designed on the current grassy land. One option has been proposed, which has been elaborated in detail.
