Testing of Automated Trading Systems
Zapletal, Martin ; Vrábel, Lukáš (referee) ; Petřík, Patrik (advisor)
This thesis deals with testing of automated systems used for stock market trading. The reader acquires basic knowledge about financial markets and stock market. Subsequently, performance indicators for the whole trading system and for the prediction model used in the system are introduced. The explanation of influence of input data selection on trading system performance is the most crucial part of the paper. Selected trading system tests were done using the application, which was made as a part of this thesis. Results of these tests are also presented.

Client-Server Relationship in Web Applications
Kučera, Petr ; Petřík, Patrik (referee) ; Šperka, Svatopluk (advisor)
This paper conducts a research in the field of transferring application logic to clients in web applications in order to reduce server load. It examines actions that can be performed on the client side in area of generating HTML code from structured data and data manipulation operations eliminating the need to communicate with server. It describes implementation of a JavaScript framework which turns this knowledge into practical use. It shows its usability on a simple information system. The results of the measurements show that the goal has been achieved and that the framework shows the way in which web applications with a strong emphasis on reducing server load can be made.

Systems that Combine Automata and Grammars
Petřík, Patrik ; Křivka, Zbyněk (referee) ; Meduna, Alexandr (advisor)
This work deals with Systems that combine automata and grammars. We investigate their properties compared with grammar systems and automaton systems. Work is focused on systems, which components are finite state automata, right linear grammars, pushdown automata or context free grammars. We also investigate usage of these systems in compilers.

Automata Systems
Petřík, Patrik ; Lukáš, Roman (referee) ; Meduna, Alexandr (advisor)
This work deals with automata systems. We define parallel automata systems and parallel communicating automata systems communicating by transitions, whose components are finite state automata. We investigate their properties compared with grammar systems or grammars.

Neural Networks and Prediction of Time Series
Sviták, Jiří ; Šperka, Svatopluk (referee) ; Petřík, Patrik (advisor)
Bachelor's thesis studies neural networks that are used for time serie prediction. Particularly it is feedforward neural network with backpropagation learning algorithm, neural network with radial basis functions and higher order neural network. Various parameters of these networks are tested and comparised. Testing is performed on time series of historical prices of financial markets. Other neural networks and other forecasting methods of financial markets are mentioned briefly.
