Object recognition using 3D convolutional neural networks
Moravec, Jaroslav ; Lokoč, Jakub (advisor) ; Straka, Milan (referee)
Title: Object recognition using 3D convolutional neural networks Author: Jaroslav Moravec Department: Department of Software Engineering Supervisor: RNDr. Jakub Lokoč, Ph.D., Department of Software Engineering Abstract: With the fast development of laser and sensor technologies, it has become easy to scan a real-world object and save it in a digital format into a persistent database. With the rising number of scanned 3D objects, data man- agement and retrieval methods become necessary. For various retrieval tasks, effective retrieval models are required. In our work, we focus on effective classifi- cation and similarity search. The investigated approach is based on convolutional neural networks representing a machine learning method that boomed in recent years. We have designed and trained several architectures of 3D convolutional neural networks and tested them on state-of-the-art benchmark 3D datasets for 3D object recognition and retrieval. We were also able to show that the trained features on one dataset can be then used to predict class labels on another 3D dataset. Keywords: Object recognition, 3D convolution, neural networks

Bitcoin - Legal Aspects and Regulation
Moravec, Jiří ; Kohajda, Michael (advisor) ; Kotáb, Petr (referee)
in English The motivation for this thesis is to analyze Bitcoin as Bitcoin is still a new phenomenon and requires an economical, legal, and legislative evaluation. In this thesis we seek an answer to the question what is Bitcoin. This thesis is divided into three main blocks, within them we use analytical, descriptive, and comparative methods. In the first part, we aim mostly on the economic side of Bitcoin, comparing Bitcoin to money in general sense. In the second part, we argue whether Bitcoin shall be considered a thing in a legal sense under the Czech law. In the third part, we describe the current Bitcoin's regulatory situation and suggest a drafting of Bitcoin specific regulation. The conclusion of this thesis is that Bitcoin is a digital medium of exchange that cannot be considered money or currency. To the extent, Bitcoin might be interpreted in ways where it does not satisfy the legal definition of a thing in legal sense, but for regulatory purposes it shall be, at least for now, considered a thing in legal sense. We also suggest that Bitcoin shall be systematically regulated by imposing various duties on persons who's scope of business is relating to the Bitcoin.

Brontosaurus Movement as a phenomenon of leisure activities of Czechoslovak youth in the years between 1974 and 1989
Moravec, Jiří ; Havlůjová, Hana (referee) ; Hnilica, Jiří (referee)
The rigorous thesis deals with involvement of young people in nature conservation within the Brontosaurus Movement, both children under 15 years of age and teenagers. The work is primarily based on documentation of the Communist Party of Czechoslovakia, Socialist Union of Youth, Security Services Archive and on private archives of former activists of the Brontosaurus Movement and magazine Mladý svět (Young World). Structured interviews with the former Brontosaurus Movement activists are the most important source of knowledge. One of the main goals of the work is to map the history of the Brontosaurus Movement and the extent to which the movement activities were influenced by Party and Union bodies. The work was concurrently confronted with a wide variety of personal testimonies. The work should contribute to development of civil society and environmental education.

Scope and mode of damages
Moravec, Jaroslav ; Šustek, Petr (advisor) ; Salač, Josef (referee)
This thesis' main focus lies in the analysis of the new statutory provisions pertaining to the civil liability for damage and identifying the differences between the old Civil Code (Act No. 40/964 Coll.) and the newly enacted Civil Code (Act No. 89/2012 Coll.), which brought about major changes with respect to the traditional regulation of liability for damage, which dated back to the enactment of Austrian ABGB in 1811. In this thesis I will try to analyse these changes and critically assess their impact and improvements over the old regulation and bring forward the controversial points and drawbacks of the new Civil Code. In the first and mostly theoretical part of the thesis I will focus mainly on the analysis of the new concept of civil liability which differs from the major view of the civil theory. I will also focus on the change of terminology resulting from these conceptual changes. The second part of this thesis will be less abstract and focus more on the new differentiation between the contractual liability for damage, i. e. liability arising out of the breach of a contract, and the delictual liability for damage, which arises out of the acts violating the statutory provisions (the written law). This thesis consists of three main sections, which are further divided into subsections. The...

Simultaneous confidence intervals dual to stepwise methods of multiple comparison
Moravec, Jan ; Komárek, Arnošt (advisor) ; Hlávka, Zdeněk (referee)
The central theme of this thesis is the construction of simultaneous confidence regions (SCR) corresponding to stepwise multiple comparison procedures (MCP). The first chapter is devoted to the theory of multiple comparisons, including the class of closed testing procedures which contains every MCP that strongly con- trols the familywise error rate. The second chapter is concerned with the gene- ral principle of construction of SCR corresponding to closed testing procedures. These general results are used in the third and the forth chapter for deriving the SCR corresponding to a subclass of closed testing procedures which are based on weighted Bonferroni tests. The SCR corresponding to the Holm, the Holm(W), the fixed-sequence and the fallback MCP are derived explicitly. The theoretical results are numerically illustrated on a bioequivalence study. In the fifth chapter we briefly discuss the SCR corresponding to the Hommel, the Hochberg and the step-down Dunnett MCP.

Ecology,ethology and variability of european green lizard Lacerta viridis in Natural reservation Tiché údolí
Chmelař, Jan ; Rehák, Ivan (advisor) ; Moravec, Jiří (referee)
The European green lizard, Lacerta viridis, is in the Bohemia region stated as critically endangered species. Populations in this region are located beyond the northern border of continuous range of this species and are closely related to the "riverine phenomenon", and deeply engorged river valleys. The chosen locality in Tiché údolí is a subject to a long-term conservational management aimed to strengthen and maintain abundance of the local population. This management is a direct output of a previous study of this population performed in years 1995-1997. Main goal of the presented study is to compare current population characteristics with the older study. The locality has been visited 119 times in years from 2011 to 2014. The studied population now displays higher abundance and inhabits a larger area. The author also performed a spatial analysis of the places with presence of an observed individual in order to determine and evaluate significance of the chosen abiotic factors for habitat discrimination. The results indicate that positive discrimination is based on the presence of a rock debris and a hiding place. Strongest factors towards negative discrimination were high percentages of grass and high vegetation coverage. This study also contains and discusses ecological, ethological and...

Systematics, Phylogeny and Biogeography of the gecko genus Hemidactylus (Reptilia, Gekkonidae) in Arabia and the Near East.
Šmíd, Jiří ; Moravec, Jiří (advisor) ; Kotlík, Petr (referee) ; Rehák, Ivan (referee)
(in English) Until relatively recently, the gecko genus Hemidactylus was considered to contain only several hard-to-distinguish species in the eastern Mediterranean and the Arabian Peninsula. This was mostly given by the apparent morphological uniformity of the geckos in combination with their often synanthropic lifestyle, which facilitated the dispersal of some of the species over large ranges. However, our understanding of the diversity of the genus was about to change with the onset of molecular phylogenetic methods that became extensively available and routinely applied to tackle the questions of systematics and phylogeny of all kinds of organisms. This thesis focuses on resolving the phylogeny, systematics, and biogeography of the Arabian Hemidactylus. Using an unprecedented sampling of over 500 samples of more than 40 Hemidactylus species from the eastern Mediterranean, Arabian Peninsula, Socotra, North and East Africa and Iran and sequencing up to six genes (two mitochondrial - 12S rRNA, cyt b; four nuclear - cmos, mc1r, rag1, rag2) I reconstructed the time-calibrated phylogeny of the arid clade of Hemidactylus, inferred its complex biogeographical history in the region, and detected seven potentially new species. The results of the biogeographic analyses indicate that the current...

Phylogeny of selected genera of geckos in the Mediterranean and adjacent regions
Červenka, Jan ; Kratochvíl, Lukáš (advisor) ; Moravec, Jiří (referee) ; Gvoždík, Václav (referee)
Phylogeny of selected genera of geckos in the Mediterranean and adjacent regions Jan Červenka Ph.D. thesis Abstract This Ph.D. thesis is composed of three published articles and one manuscript, and is focused on the phylogenetic relationships of selected species of geckos from the Mediterranean and surrounding areas. The group of geckos of interest shares the common characteristic of an absence of adhesive lamellas on their toes. Historically, it was assumed that these species were closely related. Molecular-phylogenetic approaches were used in order to reveal the phylogenetic relationships within this group, especially using the sequential data from mitochondrial genes. Morphological characteristics commonly used in lizards were studied in connection with the ecology of the group. This thesis provides the first more detailed view of the phylogeny of the studied species. The results show that the genus Cyrtopodion, previously considered as monophyletic, in fact is not monophyletic as the genera Bunopus and Agamura represent its inner groups. Mediodactylus, the subgenus of Cyrtopodion, forms monophylum but is not closely related to the other members of the genus and so was reclassified as the independent genus. The enigmatic and yet so far very poorly studied genus Carinatogecko was discovered to be the...

Issuance of money by the central bank and its prospect after accession to the European Monetary Union
Moravec, Jaroslav ; Karfíková, Marie (advisor) ; Kohajda, Michael (referee) ; Dřevínek, Karel (referee)
Issuance of money by the central bank and its prospect after accession to the European Monetary Union (abstract) The presented thesis analyzes the problems of issuance of money by the Central Bank in the Czech Republic. The issuance of money is analyzed particularly from the viewpoint of its legal regulation but attention is also paid to its practical implementation in the official practice of our Central Bank. The aim of the thesis is to comprehensively elaborate substantial part of the legal regulation in this area. Attention is paid particularly to applicable legal regulation but also to regulations that have been repealed in the period from establishment of the Czech Republic to the present time. This area of our day to day life has not been frequently explored and there is only minimum related financial-law literature. This, on the other hand, provides more space for the analysis of little known information from official practice. The first part of the thesis provides an overview of the history of issuance of money in our territory after 1918. Initially, it deals with the Austro-Hungarian crown currency and its banknotes and coins that had been circulating in this country after the establishment of the independent Czechoslovak state. It further analyzes the development of cash circulation of the...

Ontogeny and evolution of body size and sexual size dimorphism in reptiles
Frýdlová, Petra ; Frynta, Daniel (advisor) ; Moravec, Jiří (referee) ; Zrzavý, Jan (referee)
Monitor lizards (Varanidae) are morphologically very uniform in body shape, but much diversified in body size along both phylogenetic and ontogenetic axes. A striking sexual size dimorphism exists in monitor lizards; they are capable of fast growth, metabolism and sexual maturation. I collected the data concerning body size of particular species and verified the validity of Rench's rule, which said that there is bigger difference in body size of a conspecific male and females growing with larger body size of the species. Males are markedly bigger than females. In the next step, I focused on the model species of monitor lizards, Varanus indicus. I monitored its ontogeny very carefully. I found that this monitor lizard has pronounced sexual size dimorphism, but there are only small differences in body shape. It is capable of rapid growth and sexual maturation. The sexual dimorphism in body shape is only poor, but still measurable right in those places where the selection pressures were expected. Blood sampling monitored biochemical and haematological parameters. The concentrations of the biochemical parameters revealed the economy of resources of particular sexes partially, the costs of body growth and reproduction. Although both sexes produce the same amount of biomass (the body growth of males vs. the...
