Civil service Act - Development and result
Staněk, Michal ; Svoboda, Petr (advisor) ; Millerová, Ivana (referee)
Civil service Act - Development and result Abstract The new Civil Service Act (CSA) is a significantly amended version of the previous Civil Service Act № 218/2002 that never came fully into force. This thesis briefly describes the main principles and reasoning behind the proposed legislative measures, taking into account specific socio-political context and reflecting previous practice of public employment in the Czech Republic. During 21 years of its existence, the Czech Republic was governed by 13 different governments. In average, the state witnessed change in its leadership every 18 months. This political instability left a significant mark on the Czech public administration that continuously suffered from excessive political interference. In connection with the accession to the EU, the Civil Service Act approved by the Commission was adopted in 2002. Its entry into force, however, was five times postponed by numerous Czech governments, allegedly because of high budgetary demands of the implementation (the reason that has never been proven). The employment of state employees was based on the Labour Code and they did not enjoy any special legal protection. Frequent changes of top and middle management of the administrative bodies that usually followed after each political change led to the loss of...

Switched power supply with current limiting
Staněk, Michal ; Brančík, Lubomír (referee) ; Kubíček, Michal (advisor)
This thesis is focused on design and construction of switched mode power supply with continuous regulation of output voltage and current. The Power supply is designed as a switching power supply to reduce its weight and dimensions. To reach better parameters, it consists of two separate converters. The first one is isolated step-down controller with transformer. It supplies output the second controller (adjustable) and the measuring section with stable voltage. Input converter is designed as a simple single-transistor flyback converter. The TOPSwitch circuit was selected to reduce number of components. Output bench power supply is non-isolated buck converter with single transistor. For second converter the TL594 was selected as a control circuit, which typical aplication was modified to fulfill requirement of the bench power supply. Processor ATmega16 was used to show both required and actual values of current and voltage on a display.

Design of a forming machine for production of a stainless steel cup with follow die
Staněk, Michal ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
My dissertation describes the procedure and results of designing a single-purpose machine, which is designed for forming a stainless metal product from an initial semi-finished product. This semi-finished product is a 0.28mm-thick stainless-steel plate. The introduction of my dissertation outlines the evolution of the pulling technology in the Czech Republic and abroad and describes its further details. This research part also includes an overview of individual machines according to the CSN. The practical part is then further dedicated to the exploration of individual issues and requirements for designing the machine itself as well as designing the machine according to the requirements of the final pulled product.

Small rotor dynamic balancer
Staněk, Michal ; Vyskočil, Pavel (referee) ; Kubíček, Michal (advisor)
Balancing of rotors is used to remove unwanted vibrations caused by uneven distribution of mass around the axis of rotation of the rotor. Operation of an unbalanced rotor may causes shortening of bearing life, fatigue of materials and deformation of shafts. This work deals with construction of a balancing machine (balancer). Because of its good properties, a soft bearing type balancer was chosen for construction. This type of balancer achieves higher sensitivity at the cost of calibration required for each type of rotor. To capture the magnitude of vibration electrodynamics sensors were chosen. To enter data and display results a microprocessor is used.

Industrial robot application in area machinning technology
Staněk, Michal ; Matějka, Petr (referee) ; Knoflíček, Radek (advisor)
This study analyzes the application of industrial robots and manipulators in the area of cutting. It portrays the evolution of this dynamic sector and its next possible advancement. It explains the basic categorization and division of industrial robots and manipulators (IRM). The author offers an overview of various applications of IRM, with typical examples of the correct use of different types in technological processes (turning, milling, grinding etc.) in order to effectively increase the production. The study also describes two robotized technological work sites that the author personally visited and documented in detail. This study is supposed to show the indisputable advantages of employing the automating elements into the mechanical engineering and to explain the basic concept of this industry.

Modern Trends in Geography Teaching on the 2nd stage of Primary Schools shown on "The Earth in Space"
STANĚK, Michal
The main aim of my thesis is to create a suggestion of my own teaching materials for teaching the topic "The Earth in Space" in the context of geography on the 2nd stage of Primary schools which includes not only workbook for students but also a methodological guide for teachers and additional outputs usable for an interactive whiteboard. The teaching text itself corresponds to the principles defined in the current educational documents. The theoretical part evaluates the significance and status of the material in the curriculum in the context of the Framework Educational Programme for Elementary Education and the school educational programmes of schools monitored. The next chapter is devoted to the didactic analysis of current educational textbooks and workbooks for the 2nd stage of Primary schools which includes the subject matter. The thesis also contains an overview of selected modern elements in the teaching of geography.
