Apartment house
Havlíček, Jakub ; Vacenovská, Veronika (referee) ; Utíkalová, Ivana (advisor)
This bachelor thesis deals with the project of two apartment blocks “A” and “B” in the village Rudíkov. These two objects are located in sloping terrain and both have two floors aboveground and one floor underground. In the apartment block “A” there are six apartment units aboveground and four garage units and storage area underground. In the apartment block “B” there are eight apartment units aboveground and two wheelchair accessible apartments with common storage areas underground. The objects are designed from a construction system made of ceramic blocks. The ceilings are monolithic and the roof is hipped with trusses. The thesis provides documentation for realization of the construction.

BLDC drive control
Havlíček, Jiří ; Buchta, Luděk (referee) ; Otava, Lukáš (advisor)
The bachelor thesis is focused on problems of sensor control of Brushless DC Electric motor (BLDC) using hall-effect sensors. The BLDC motor is connected to 3-Phase low-voltage board which was produced by Freescale Semiconductor, Inc. The board is adapted to control electrical motors by MC56F8006 signal microcontroller. The next part is devoted to implementation of interconnection of the machine with the Matlab/Simulink programme using the MF 624 multifunction I/O card. Cascaded control, current and speed loops are used for the final configuration. The former loop is realized in the signal microcontroller, the latter one in the Simulink programme.

Encoding algorithms of soft cryptography
Havlíček, Jiří ; Burda, Karel (referee) ; Člupek, Vlastimil (advisor)
This bachelor's thesis deals with so called lightweight crptography which is specified for low-efficiency hardware. The first part of my thesis explains basic terms and principles of cryptography, difference between symmetrical and asymmetrical encryption including description of the most widespread examples of both of these cryptography's branches. The thesis continues with the description and parametric comparison of newly developed algorithms focusing on lightweight cryptography. I specially pay attention to current and block ciphers and hash functions. Afterwards the thesis describes limited computing power hardware. This is about device which is limited from the point of view of power supply and size of chips. The description is focused on smart cards, RFD chips and microcontrollers. The practical part deals with testing of current ciphers which are designed for software implementations and with testing of current ciphers designed for lightweight cryptography. Results of the tests provide comprehensive view of differences of output of individual ciphers specified for different implementations.

Oxygen cycle during pulse charging of lead-acid accumulator
Havlíček, Jiří ; Vaněk, Jiří (referee) ; Křivík, Petr (advisor)
This master´s thesis applies to puls charging of lead-acid accumulator and arising oxygen cycle while charging. First part of the thesis is focused on potential dividing of lead-acid accumulators and their construction. I also focus on priciples of submerged electrodes accumulator, gel accumulator and AGM accumulator based on oxygen cycle. The next topic are thermal and degradation processes inside accumulators and their influence on capacity and lifespan. In theoretical part am I describing ways of charging and I also point out possitives and negatives. Practical part focuses on producing experimental cell and its form. Experimental cell is tested to different modes. I evaluate their influence on temperature inside the cell, intensity of oxygen cycle and capacity. I compare their influence on duration of charging cycle to another possible charging modes.

Small strain stiffness of soils and methods of its measurement
Havlíček, Jaroslav ; Miča, Lumír (referee) ; Chalmovský, Juraj (advisor)
This thesis consists of theoretical and practical part. Firstly, the soil behaviour at small-strain range and its physical nature are described. Subsequently, the individual soil parameters affecting the value of small-strain shear modulus and the shape of the stiffness reduction curve with increasing shear strain are described. The individual methods of measuring the small-strain stiffness in the laboratory and in-situ with a more detailed explanation of the evaluation of measurements using bender elements are given in the last chapter of the theoretical part. In the practical part, a device for measuring small-strain stiffness using bender elements was put into operation. The used laboratory equipment is described first and then the parameters of tested soil are given. The main chapter is measurement and evaluation of the impact of software and hardware settings and the influence of effective stress of soil on the small-strain shear modulus that is compared with predictions of empirical expressions from the literature.

REALITY
Kadlčák, Šimon ; Havlíček, Jiří (referee) ; Sterec, Pavel (advisor)
My diploma project at Faculty of Fine Arts in Brno Reality is based on video docummentation of football fans, shot at the match of 24th round of the 1st Czech football league between Slavia Praha and Hradec Kralove in spring 2017. Presentation form of multi-channel installation enables the viewer to watch parallel actions. The center whole shot displays the tribune of Slavia ultras as massive, highly-coordinated collective body. Simultaneously filmed detailed shots display individual diversity, invisible in the image of the whole. Using the method of juxtaposition, I pose questions on the nature and relationship of an individual and collective. Depending on current perspective,, the individual might seem as independent on the collective, or it might easily seem to be firmly linked together. In the Documentation of Diploma Thesis I suggest several ideas on the individual/collective relationship: the role of cultural and other dependance, the nature of time, or the role and relevance of glance and observation.

New town hall for the district Brno-North
Havlíček, Jan ; Havlíček, Tomáš (referee) ; Nový, Vítězslav (advisor)
The purpouse of this thesis was finding the way to design new city hall of district Brno - Sever. It builds on a urban study from previous semesters. I have found the pattern for my concept in ancient public proto-democratic structures - agoras, phorums. By creating some sort of a district with various (not only city hall) programmes, we gain a diversified, living and vibrant public spaces, outdoors as well as indoors.

LABORARTORY BRNO
Havlíček, Jan ; Sládeček, Svatopluk (referee) ; Kratochvíl, Jan (advisor)
The concept: gallery ~ temple. Powerful corner mass, smooth, absent perforation, it pushes viewer to thinking about human scale and scale of a structure. The effect is strenghtened by it's concrete surface with noble texture. In adition, the object logially conceals exisitng development. Insides of the building protects the visitor from noisy streets and on a small area, they offer generous, yet subtle spaces of exhbition (1500m2). Two, more rational looking, masses, at sides of the main one, match, with their height and roof profile, surrounding buildings. These two contains service and administration areas on one hand and comercial space, café and workshops on the other.
