Design of actuators for the butterfly safety valve
Melecký, Josef ; Halfar, Jiří (referee) ; Ripel, Tomáš (advisor)
The bachelor s thesis desribes desing of actuator and safety mechanism for a butterfly safety valve. Based on research mentioned in the introduction was chosen type of actuator, whose particular parameters come out of moment proportions calculated according to concrete requests of external firm. Another part of the thesis concerns design of safety mechanism for critical status. In the final part of the thesis parameters of design actuator system are stated, focusing on kinematics motion of the butterfly valve.

Hydraulic control of butterfly valve
Ševčík, Vlastimil ; Svoboda, Petr (referee) ; Brandejs, Jan (advisor)
This bachelor's thesis deals with construction and design for hydraulic servomotor bracket and valve's hydraulic control. The main part describes the history and types of butterfly valves. Construction part deals with selection of optimal design and there is made the strength analysis for the selected type of bracket.

Reconstruction of the Hranice weir
Křenek, Tomáš ; Uhmannová, Hana (referee) ; Julínek, Tomáš (advisor)
The bachelor´s thesis is the modification of the existing weir structure in Hranice on the river Becva at river kilometer 38,300. The first part is a search dealing with the topic of weir structures. In the second part, the locality of interest is first described. Then there is a mention of the historical development riverbed of the Becva and the original fixed weir, which goes on to describe the existing weir structure. Subsequently, the individual reconstruction proposals were evaluated and the most suitable variant was selected, including the choice of the type of substructure construction, movable valve and the fish pass. Last but not least, hydrotechnical calculations were performed, witch also contain a partial calculation of the stability of the proposed structure.

Design of a weir structure with movable locking elements
Staněk, Tomáš ; Uhmannová, Hana (referee) ; Julínek, Tomáš (advisor)
The aim of this Bachelor thesis is the design of the movable barrier structure on the site of the existing fixed weir in the city district of Brno - Husovice on the Svitava River in km 7,820. The first half of the thesis deals with theoretical aspects concerning the design and utilization of weir structures. In the second half of the thesis, theoretical knowledge is applied to practical design of the moving weir structure. First of all, the locality of interest including adjacent objects is positioned and described. Subsequently, a critical evaluation of the scope and quality of input materials is performed. The following is the selection of the appropriate type of substructure construction and movable valve. Based on the chosen type of construction, hydrotechnical calculations are performed, which include partial assessment of weir stability. The thesis also includes drawings and summary description of the designed structure.

Engine Motormanagement Software
Huška, Lukáš ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
This master thesis deals with ignition systems which are used in cars vehicles with gas engines and also with setting of the best moment of ignition of gasoline-air mixture in cylinders of engine. Ways of gas injection at diesel engines and their control systems are also described in this thesis. Next chapter deals with control unit and describes main actions which are necessary for today’s motor vehicles. As illustration is used example of succession of actions which are necessary for calculation and setting regular value of pre-ignition. At the end is shown animation, which can be used for practice lessons in a subject Automobile Electric and Electronic Systems as a example. It will simplify understanding of described activities which are all accomplished by central control unit. For purposes of laboratory lessons is in this thesis also discussed measuring of engine performance with changes of parameter of central control unit.
