Bruntál city bypass I/45 with connection to the planned northern bypass I/11
Dlhopolček, Michal ; Patočka, Miroslav (referee) ; Smělý, Martin (advisor)
The subject of this master's thesis is a technical study for the east bypass I/45 around city Bruntál and solution for its mutual connection with the planned north bypass I/11. This work seeks for the most efficient and comfortable connection between both bypasses, as well as the safe movement of vehicles on I/45 bypass. One variant has been elaborated in more detail. The reason for elaborating this work is to divert traffic from the center of the city of Bruntál and create an effective connection between both bypasses.

Current source for the switchgear thermal test
Košíček, Jiří ; Huták, Petr (referee) ; Patočka, Miroslav (advisor)
This thesis describes the design of semiconductor source for laboratory measurements of switchgears. The proposed source is able to use 16-250Hz frequency, fulfilling the standard value of voltage and current distortion. There are explained the theoretical knowledge of various types of inverters without transformer in the thesis. Furthermore, a circumferential proposal of source is made, which includes calculating the desired properties of individual components, their choice from offers from various manufacturers, and subsequently is constructed the total design solution. It is described the control and management of designed source and it is evaluated for the function finally.

Adjustment an intersection of Přístavní x Obvodová in Brno
Nykodým, Miloš ; Patočka, Miroslav (referee) ; Smělý, Martin (advisor)
The one-lane roundabout is designed at the crossing point of road II. Class (Ob-vodová) and local road (speed-A, Přístaviště) in Brno. The current state is unsatis-factory. The danger is at risk due to the increased maximum permitted speed before the junction and also because of the MHD JMK bus stops, which are cur-rently solved in the form of a lane stop in the local road, or with partial bus bay. The goal of this bachelor thesis is to maximize the safety of traffic participants. Furthermore, emphasis is placed on minimizing interference with existing struc-tures, the environment and aesthetics.

DC/AC inverter for small asynchronous machine
Pavlík, Ondřej ; Patočka, Miroslav (referee) ; Červinka, Dalibor (advisor)
The aim of this Bachelor thesis is to propose three-phase converter of low power 100W for driving the asynchronous motor. The device is suitable for construction with fans. This proposal was optimized in light of close price and of technical practicability. The arrangement is possible to use in less exacting applications where it was guarded high price of common converters so far. For allocation catalogue scheme were chosen acceptable components and designed the board of printed circuits.

Substituting circuit of an induction machine
Běloušek, Radim ; Cipín, Radoslav (referee) ; Patočka, Miroslav (advisor)
Although induction motors are the simplest and most working reliability machines, is the identification of the parameters of their substituting circuit very difficult. There is solved the identification of the parameters of the substituting circuit in the T-network and ? –network in this work. The work also includes the proposal of magnetic circuit of the induction motor, the calculation of magnetizing and leakage inductances and resistances of the machine. The conclusion of the work is devoted to the sensitivity analysis of current and torque characteristics of induction motor upon the change of the single parameters of the substituting circuit.

Modifying local road parking spaces in the village Kvasiny
Ešpandrová, Bára ; Patočka, Miroslav (referee) ; Smělý, Martin (advisor)
The aim of my thesis is to modify a local road in village Kvasiny and to connect it to current adjacent roads. The thesis also focuses on designing of parking places for visitors of the local sports centre. Proposed building adjustments will be situated on plots owned by local municipality only, without any land take of contiguous estates. Last but not least the thesis aims on passportisation of parking places within the whole village.

Parameter identification of the asynchronous machine substituting circuit
Otýpka, Jan ; Běloušek, Josef (referee) ; Patočka, Miroslav (advisor)
This work deals the precise identification of the substituting circuit parameters of the asynchronous machine for the gama-network, inverted Gama-network, T-network. I make use the best identification of the substituting circuit parameters of the asynchronous machine experimental method, theoretical procedurs and konstruction dates. In this work I solve various methods of identification and i compare solving like construction moment's characteristics from these establishen parametrs. Further I'm solving in my work comparations of two the costruction of them is similar with asyhronous mashins with power of 2,2kW , 2p = 2.
