Using XML technologies to apply design patterns
Hála, Vojtěch ; Bednárek, David (advisor) ; Mlýnková, Irena (referee)
Although contemporary programming style involves massive use of design patterns, programming languages does not offer suitable means tu support their application. Aim of this work is to show in practice that modern XML technologies, namely XSL Transformations, allow developers to avoid some routine tasks required by the objective language itself. This reduces the probability of errors, allows developers to focus on the key parts of the design, and makes maintaining the code markedly easier. These benefits come to light especially in large projects with hundreds to thousands of classes with complicated relations. In this Thesis we demonstrate these ideas on an example of a C++ compiler project.

RDF querying
Dokulil, Jiří ; Vojtáš, Peter (referee) ; Pokorný, Jaroslav (advisor)
The RDF is one of the basic technologies of the Semantic Web. It is a language describing resources on the web. It de nes the format and semantics of such data but does not provide query capabilities. The aim of this thesis is to create system capable of querying RDF data. We have created a partial implementation of the SPARQL query language. The SPARQL standard is currently being developed by the W3C Consorcium. We have chosen the Oracle relational database to store the RDF data. The proposed database schema allows us to evaluate SPARQL queries by translating them into SQL queries. The proposed methods have been tested on a large set of RDF data. We have created several examples of SPARQL queries, translated them to SQL, and measured the evaluation time of the translated queries. Afterwards, factors with negative impact on the evaluation speed have been analyzed. We have proposed two ways of improving the evaluation times based on this analysis, implemented one of them, and measured its e ffects.

Economic Analysis of Judicial Activity
Zabranská, Monika ; Kühn, Zdeněk (advisor) ; Munzi, Tomáš (referee)
The thesis deals with the problem of the monopoly structure of the modern justice system and the heavy regulation of most fields of dispute resolution. In this system, judges themselves comprise a self-interested group seeking relaxed regulation and increased rights from the government. The thesis describes inefficiencies and dangers stemming from the lack of market control of the modern justice system and suggests an alternative in the form of a private justice system. The purpose of this paper is to examine both the problem of successful implementation of competition into the current justice system, while describing various models as to how the private justice system could function without state control, with examples from history. This paper further examines the economic differences between private and public justice systems in terms of incentives, efficiency, the process of law creation, speed, and consumers' satisfaction, as well as the conditions under which different systems work best. The main conclusion of this paper is that society should allow all subjects desirous of opportunities to provide goods and services through new enterprises, even in areas currently the exclusive domain of the state, as doing so brings an increase in quality, speed of solution/service, and innovation.

Dynamika živých organismů
Vondrák, Marek ; Pelikán, Josef (advisor) ; Kavan, Ladislav (referee)
The computer animation of articulated figures is one of the most interesting and the most developing areas of the modern computer graphics. The goal of this thesis is to get the reader acquainted with the theory of constrained rigid body simulation, which is subsequently used to construct a generic rigid body simulator with constraints and friction and the figure library suitable for the animation of articulated human-like figures. Articulated figures are represented by sets of rigid bodies (segments) connected by joints and their motion is determined by the dynamics of the corresponding segments. Additional constraints, specifying e.g. desired angles at joints or the positions of selected sites on the surface of the figure segments, allow to control the figure motion. A rich set of interactive demonstration examples presents the features of the actual simulator and the capabilities of the figure library to process motion capture data (replay motion capture data, adapt the data to external influences, map the "raw" motion capture data to the motion of figure segments, etc).

Zilvarová, Barbora ; Řihák, Pavel (referee) ; Mohapl, Martin (advisor)
The diploma thesis deals with construction technological project of shopping centre Breda & Weinstein in Opava. The thesis handles technological prescriptions of cast-in-place reinforced concrete constructions and ventilated facade made of large format precast elements with graphical surface. There is machine assembly, design of site equipment, control and test plan and computation of time of formwork dismantle for the realization of reinforced concrete constructions. There is also time and financial plan, itemized budget with bill of quantities and construction schedule for earthwork, building foundations and cast-in-place constructions.

Order book dynamics
Peržina, Vít ; Swart, Jan (advisor) ; Večeř, Jan (referee)
Main goal of this thesis is improvement of an order book model so that it behaved more realistically, based on a model developed by J. Plačková in her diploma thesis in 2011. We consider this simple model for evolution of order book in which limit orders of unit size arrive according to independent Poisson processes. Frequency of buy limit orders below resp. sell limit orders above a given price level is described by demand and supply functions. Buy (resp. sell) limit orders that arrive with price above (resp. below) the current ask (resp. bid) price are converted into market orders and cancellation of orders is not allowed. We extend this model by introducing market makers who place at the same time one buy and one sell limit order with current bid and ask prices. We show how introducing market makers reduces the spread that in the original model was unrealistically large and also show a method of calculating the precise rate of market makers needed to reduce the spread to zero. 1

Gradient Boosting Machine and Artificial Neural Networks in R and H2O
Sabo, Juraj ; Bašta, Milan (advisor) ; Plašil, Miroslav (referee)
Artificial neural networks are fascinating machine learning algorithms. They used to be considered unreliable and computationally very expensive. Now it is known that modern neural networks can be quite useful, but their computational expensiveness unfortunately remains. Statistical boosting is considered to be one of the most important machine learning ideas. It is based on an ensemble of weak models that together create a powerful learning system. The goal of this thesis is the comparison of these machine learning models on three use cases. The first use case deals with modeling the probability of burglary in the city of Chicago. The second use case is the typical example of customer churn prediction in telecommunication industry and the last use case is related to the problematic of the computer vision. The second goal of this thesis is to introduce an open-source machine learning platform called H2O. It includes, among other things, an interface for R and it is designed to run in standalone mode or on Hadoop. The thesis also includes the introduction into an open-source software library Apache Hadoop that allows for distributed processing of big data. Concretely into its open-source distribution Hortonworks Data Platform.

Analysis of integrated transport systems in big cities
Šimůnková, Martina ; Wokoun, René (advisor) ; Vychodil, Petr (referee)
V diplomové práci se zabývám integrovanými dopravními systémy velkých měst. V první části mapuji problematiku integrovaných dopravních systémů obecně. Poté uvádím několik příkladů ze zahraničí a podrobněji se věnuji pražské integrované dopravě. V praktické části práce provádím srovnání pražského a mnichovského integrovaného dopravního systému v oblastech územního rozsahu dopravní sítě, tarifu a jízdného, délek tratí a linek a dopravních výkonů. Pomocí SWOT analýzy hodnotím silné a slabé stránky, hrozby a příležitosti pro pražskou integrovanou dopravu. Výsledkem mé práce jsou doporučení a návrhy možností dalšího rozvoje Pražského integrovaného dopravního systému.
