Feasibility study for the upgrade of LMS Moodle
Havlíček, Jiří ; Husa, Jiří (advisor) ; Karel, Karel (referee)
Bachelor thesis "Feasibility study for the upgrade of LMS Moodle" deals with the analysis of data and database structures of Moodle versions 1.4 and 3.0, their mutual compatibility and the possibility of transferring from an older version to the new one. The theoretical part introduces the basic software components required for proper function of LMS Moodle environment, their characteristics with the possible justification for their selection and use. The practical part compares the specific differences in data and database structure of both versions, which ultimately appears to be completely different, i.e. non-transferrable from the old version to the new LMS Moodle. The practical part also step by step describes official upgrading procedure which is recommended by LMS Moodle developers. Thesis is concluded by summarizing the test results and subsequent recommendation of the general procedure for upgrading the website. This upgraded web environment could offer more modern look and use of the new features to all students, teachers and visitors.

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.

A Night in the Mill
Topínková, Anita ; Havlíček, Jiří (referee) ; Zet, Martin (advisor)
Be moving, seek, hunt for sth, can´t find it so far, that is a promise of paradise, or a paradise itself. Mobility as a protest, pursuit of adventure, searching for escape, authenticity or identity.

Holographic Hieroglyph
Sobotková, Adéla ; Havlíček, Jiří (referee) ; Cenek, Filip (advisor)
Topics fragmentary , symbolism and memory are the basic elements of creation and thinking Adele Sobotková (1987 ) . In her installation made of clay and covered with a udusaných objects together with the soil can walk, touch , read, intervene . This raises a cryptographic magical space full of mysterious objects in the video that represent clusters of personal hieroglyphic symbols and structures without the possibility of accurate decryption. These enigmatic characters are like glass or water , are changing , floating landscapes and refer to feelings of uncertainty, and forgetting the past, which is not entirely clear - is revealed as a mirage . Hologram is a representation of reality or reality that no longer exists but in time, or never existed , dream hi - technology , the current symbol of immortality, infinite and preservation in time. " Holographic hieroglyph " is a fluid phenomenon with varying meanings depending on its reading , the transcript or constant metaphor memories and the zpřítomňování hand in hand zpřítomňování a revival oblivion . Unclear character that has certainly not decipher , and yet we have it all in front of him , we see him from all sides , but also through him is the present and yet unreal . Great recording of uncertainty. (press release of the exhibition Holographic Hieroglyph in the Youth Gallery in Brno)

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.
