Development of the cities in the early post-socialism. The impact of the liberalization in the nineties of the 20th century to the planned development of socialist modernism
Sedlák, Jaroslav ; Kováč, Bohumil (referee) ; Wittmann, Maxmilian (referee) ; Kopáčik, Gabriel (advisor)
Housing estate quarters of urban structures, that have been built in the period of socialism, currently suffer from the necessary urban transformations and neoplasms. While both here and in many other countries of the former Soviet satellites, is a form of housing estates and their development tied by regulations and "economic players" who determine the radical architectural or urban design changes, in areas of the former Soviet Union is the current form of housing units resulted by unguided architectural and urban interventions. Though in many cases, the expansive examples that are bordering with so called "folk art", we can observe on them the functional principles of "urbanity". They may represent a potential for future design and development of housing estates in the Czech Republic. The thesis will thematize the process of using bloc-of-flats areas in Czech republic as well as in economically low powerful countries, namely Moldova and Georgia. After the collapse of the Soviet Union, while new economic system has destroyed the original urban structure so called mikrorajon, with the development of small individualism the private sector has changed the form of the city housing estate. The total economic collapse and lack of spatial regulation began to offer an accessible alternative housing and place to do business. We can discover kiosks and gradually expanding parterres of real urban type. At the same time we can see new front of street responding to space reserves and distance, as well as appearance of vertical streets inside the houses. The construction itself is no longer just a place for living, but many flats are used as offices and small businesses. Services are developed and the total value of diversity of the environment begins to grow rapidly. Typical monotony of housing units is starting to fade and transformed into a network monitoring the needs of the population. Thus the periphery offer a distinctive part of the city.

Onboard computer for electric scooter
Stříteský, Vladimír ; Burian, František (referee) ; Kříž, Vlastimil (advisor)
The aim of this thesis is clarify construction of onboard computer for electric scooter. There is description of components, from which the electric scooter is built. Within this thesis a computer simulation of accelerating scooter is created. Based on the simulation three possible ways of controlling the electric drive were proposed. Then thesis describe parts from witch control system is composed. Onboard computer and support circuits are described in more detail and explained their functions. Description of the created software is in the final part.

The Continuity Indicators Calculation of E-ON ČR Distribution Network Segment
Girga, Eduard ; Černý, Pavel (referee) ; Paar, Martin (advisor)
The aim of this master’s thesis is calculation and analysis of reliability indicators of the company E.ON Česká republika, s.r.o. distribution network in the south Moravia territory (area of former Jihomoravská energetika) for the period of one year, from 1st November 2008 to 31st October 2009. We consider events incurred on overhead or underground lines of level of high voltage or directly connected with these lines. Events originated from extensive disaster interruption of electric energy supply caused by particularly unfavourable external effects are not considered, because network components can not be efficiently dimensioned on those influences. Known aspects of the events are time of origin, time duration, place and cause of failure inception. Analysis of reliability indicators is accomplished according to different point of view. The first aspect is the hours of day, during which the event lasted. The second aspect is the hours of day, during which the event incurred. The third one focuses component pointed as reliable for the origin of the event. The last standpoint is percentage load of the line outlet, on which the event occurred. We can ordain this load as the proportion of current flowing through the line outlet in the time of event inception and of the value of maximum current set up on the protection of the line outlet. Indications mentioned in the last sentence were searched in the dispatcher centre thanks to graphical interface of application RIS JME Brno. In the theoretical part of the work there is described the structure of distribution network and its fundamental influence on the continuity of electric energy supply, the ways of evaluation and increasing of electric energy supply reliability, regulation of continuity of electric energy supply with emphasis on regulation in the Czech Republic valid until 26th February 2010 and since 27th February 2010. The last theoretical part focuses on definition of failure and differentiation of failures according to various aspects.

Control system for equipment using renewable energy sources
Novotný, Jan ; Bradáč, Zdeněk (referee) ; Benešl, Tomáš (advisor)
The work deals with design of power and control electronics for water micro source in island network. In the general part the readers are acquaints with the issue of renewable energy sources and describes commercially produced micro sources. The practical part deals with the design of its own control system and power electronics using its own control system or PLC for water micro source. The microcontrollers were used for the implementation of the control system, for which the program part was created.

Control of HVAC equipments
Zaoralová, Kateřina ; Weiglhofer,, Willy (referee) ; Rubina, Aleš (advisor)
The aim of the diploma thesis is application of the topic Control of HVAC equipments. The thesis is divided into three part – A, B, C. The first theoretical part deals with controlling/regulation in general, it focuses on controlling/regulation of HVAC equipments and it describes ways of air volume flow measurement, which relates to the third experimental part. The second part is focused on design of HVAC system in inpatient ward and fit-out for employees. In the third part was realized verification of air flow volume controller in two chosen buildings, whence in one there weren´t fulfilled manufacturer´s requirements and in the second one they were fulfilled. In conclusion there were compared measured values.

Nonlinear Control of Complex Systems by Utilization of Evolutionary Approaches
Minář, Petr ; Ošmera, Pavel (referee) ; Oplatková,, Zuzana Komínková (referee) ; Matoušek, Radomil (advisor)
Control theory of complex systems by utilization of artificial intelligent algorithms is relatively new science field and it can be used in many areas of technical practise. Best known algorithms to solved similar tasks are genetic algorithm, differential evolution, HC12 Nelder-Mead method, fuzzy logic and grammatical evolution. Complex solution is presented at selected examples from mathematical nonlinear systems to examples of anthems design and stabilization of deterministic chaos. The goal of this thesis is present examples of implementation and utilization of artificial algorithms by multi-objective optimization. To achieve optimal results is used designed software solution by multi-platform application, which used Matlab and Java interfaces. The software solution integrate every algorithms of this thesis to complex solution and it extends possible application of those approaches to real systems and practical world.

Steam turbine
Čípek, Petr ; Škorpík, Jiří (referee) ; Fiedler, Jan (advisor)
The aim of the thesis is to design a high-speed steam turbine as a small energy source. Steam turbine consists of a high-pressure, a medium-pressure and a low-pressure part with a removable condensing module. High-pressure part is designed to perform a single-stage radial turbine with axial steam outlet. The work also includes the layout of the modules and sections. To design individual parts are used steam table „X-steam“.
