Data compression
Krejčí, Michal ; Havlíková, Marie (referee) ; Čejka, Miloslav (advisor)
This thesis deals with lossless and losing methods of data compressions and their possible applications in the measurement engineering. In the first part of the thesis there is a theoretical elaboration which informs the reader about the basic terminology, the reasons of data compression, the usage of data compression in standard practice and the division of compression algorithms. The practical part of thesis deals with the realization of the compress algorithms in Matlab and LabWindows/CVI.

Fourier transformation and spectrogram analysis of DNA sequences
Krejčí, Michal ; Provazník, Ivo (referee) ; Maděránková, Denisa (advisor)
Various methods of DNA sequences modifications for frequency analysis and basic characteristics of DNA are described in the theoretical part of this thesis. Tricolor spectrograms, created by short time Fourier transform help us to recognize some characteristic patterns in DNA sequences. Practical part of this work deals with developed programme which generates spectrograms and analyse them. Last part deals with the analysis of selected sequences of C. elegans genome. Some patterns are related to data of public databases such as NCBI. Various patterns are explained from the biological nature, which relates to chromosome structure and protein coding regions. Another well recognised patterns, tandem repetitions composed of satellites, microsatellites and minisatelites are described by spectrograms as well.

Dopady změny klimatu na četnost a intenzitu sucha na území ČR
Krejčí, Michal
The main goal of this thesis is the analysis of trends of relative atmospheric humidity, absolute atmospheric humidity and water vapor pressure from years 1981-2015. Only days without precipitation were included in the input data set. The data used in the analysis comes from eight meteorological stations located in the Czech republic: Doksany, Churáňov, Kocelovice, Kostelní Myslová, Kuchařovice, Liberec, Lysá hora and Přibyslav. The statistical significance of the trends was evaluated with the Pearson’s correlation coefficient. The results show no clear evolution of the trends of the relative humidity. On the other hand, the trends of absolute humidity and water vapor pressure show significant rising trends in July (at six stations) and November (at seven stations). The July trends are probably caused by higher temperature during summer and the cause of the November trends might be caused by higher precipitation in autumn.

Analysis of Student Card ISIC Use
KREJČÍ, Michal
The Bachelor thesis is focused on the actual situation of the use of the student ISIC card. The thesis is divided into two parts, theoretical and practical. The theoretical part describes the history of the ISIC card, development and distribution, supported areas of the card, brand partnerships, as well as IT technologies associated with the card. The further description of discounts, benefits and insurance is also included. The practical part describes methods and research objectives. The questionnaire method was used in cooperation with GTS ALIVE s.r.o. company. The analysis of the use of ISIC cards was performed based on the results obtained.

Agroekologické důsledky havárie reaktorů v japonské jaderné elektrárně Fukušima I. se zaměřením na vodní ekosystémy
Krejčí, Michal
This thesis deals with agroecological consequences of the Fukushima Daiichi power plant accident and it focuses on aquatic environment. It includes short history of radioactive elements in energetics. It also includes properties of the most important fission products. The thesis describes the accident of the power plant, fission products that were released into the environment through atmospheric release and direct discharges of contaminated water, measuring and monitoring of the contaminants, their movement and accumulation in river and marine ecosystems. The thesis focuses on radioisotope 137Cs, its accumulation in river and ocean sediments, sea algae and aquatic organisms. There is a special chapter about accumulation of 137Cs in fish which are a key component in aquatic ecosystems and also they are often consumed in Japan.
