Stock Selection by Techical Analysis
Netušil, Petr ; Polách, Petr (referee) ; Sojka, Zdeněk (advisor)
This bachelor thesis is engaged in stock selection to portfolio with the help of technical analysis. In accordance with this aim the whole thesis is being structured, while at the beginning there are theoretical resources concerning exchange system mentioned, as well as basic methodology of technical analysis. These methods are further transferred into practical examples in the second part. This thesis thus describes possibilities of technical analysis in conditions of capital markets.

Expert system NPS
Plch, Miroslav ; Polách, Petr (referee) ; Jirsík, Václav (advisor)
The bachelor thesis deals with the suggestion to set a knowledge base for an expert system. Knowledge base is made for the topic of vibrations and sounds inside an automobile. The solution is based on a diagnostic expert system NPS32. The base that is produced can be used to identify the most frequent automobile defects.

Voice recognition of standard PILOT-CONTROLLER control commands
Kufa, Tomáš ; Polách, Petr (referee) ; Honzík, Petr (advisor)
The subject of this graduation thesis is an application of speech recognition into ATC commands. The selection of methods and approaches to automatic recognition of ATC commands rises from detailed air traffic studies. By the reason that there is not any definite solution in such extensive field like speech recognition, this diploma work is focused just on speech recognizer based on comparison with templates (DTW). This recognizor is in this thesis realized and compared with freely accessible HTK system from Cambrige University based on statistic methods making use of Hidden Markov models. The usage propriety of both methods is verified by practical testing and results evaluation.

Sanitary technical installations and gas pipeline in the apartment house
Polách, Petr ; Wierzbická, Helena (referee) ; Vaščáková, Alena (advisor)
The bachelor's thesis deals with the design of sanitary technical installations and a gas installations in an apartment house and with their connection to existing engineering networks. It also includes a design of a wastewater pumping facility to protect the underground rooms from the sewage flooding. It also includes a proposal for a light liquid separator, infiltration device and rainwater tank. The theoretical part is focused on gas main, fittings in gas distribution, gas pressure regulator and gas meters. Calculation and project part solves distribution of sewerage, water supply and gas pipeline in the specified object. It is a basement building with three aboveground floors and usable attic. On the ground floor of the apartment house there is a café.

Evolutionary algorithms
Haupt, Daniel ; Polách, Petr (referee) ; Honzík, Petr (advisor)
The first part of this work deals with the optimization and evolutionary algorithms which are used as a tool to solve complex optimization problems. The discussed algorithms are Differential Evolution, Genetic Algorithm, Simulated Annealing and deterministic non-evolutionary algorithm Taboo Search.. Consequently the discussion is held on the issue of testing the optimization algorithms through the use of the test function gallery and comparison solution all algorithms on Travelling salesman problem. In the second part of this work all above mentioned optimization algorithms are tested on 11 test functions and on three models of placement cities in Travelling salesman problem. Firstly, the experiments are carried out with unlimited number of accesses to the fitness function and secondly with limited number of accesses to the fitness function. All the data are processed statistically and graphically.

Instance based learning
Martikán, Miroslav ; Polách, Petr (referee) ; Honzík, Petr (advisor)
This thesis is specialized in instance based learning algorithms. Main goal is to create an application for educational purposes. There are instance based learning algorithms (IBL), nearest neighbor algorithms and kd-trees described theoretically in this thesis. Practical part is about making of tutorial application. Application can generate data, classified them with nearest neighbor algorithm and is able of IB1, IB2 and IB3 algorithm testing.

Oscillators RC for higher frequency range
Polách, Petr ; Petržela, Jiří (referee) ; Dostál, Tomáš (advisor)
This thesis deals with RC oscillators applicable in higher frequency ranges with the use of modern active elements. For individual function blocks (conveyor, current feedback amplifier, operational transconductance amplifier, voltage feedback amplifier) suitable models are suggested for the circuit simulator PSpice covering their characteristics on various levels, from an ideal one up to the full description of parasitic effects. On the basis of the study of recommended literature and company documentation various oscillator connections of the ranks 2 and 3 are suggested. By analysis through computer (PSpice, SNAP) the fulfilment of oscillation conditions, onset of oscillations were verified and by means of suitable simulations the effects of the impact on the parasitic characteristics of active elements was examined. Finally there are two oscillator connections stated and verified by simulations with the possibility of electronic retuning.

Sanitary installations and gas pipeline in the pension for seniors
Polách, Petr ; Vrána, Jakub (referee) ; Vaščáková, Alena (advisor)
This diploma thesis deals with the design of sanitary and gas installations in a boarding house for seniors and their connection to existing utilities. For the whole object there will be designed operating water supply with the use of rainwater. The diploma thesis also includes the design of a sewage pumping station, grease trap, light liquid separator, infiltration equipment and rainwater tank. The theoretical part is focused on the issues of gray water and rainwater and subsequent use as operating water. Computational part and project part solves sewerage distribution, water supply and gas pipeline in the specified object. It is a partially basement object with five floors. The object includes a surgery, a cafe and a shopping place.

Expert systems for choosing field of study
Vítek, Aleš ; Polách, Petr (referee) ; Jirsík, Václav (advisor)
The bachelor thesis deals with the suggestion to set a knowledge basis for an expert system enabling a choice of study specialization at the Faculty of Electrical Engineering and Communication Brno University of Technology (abbrev. FEKT VUT). The expert system would recommend one of the six study branches at the FEKT VUT to the Year 4 secondary school students and Year 1 winter term students of the FEKT VUT. The expert system would gradually ask questions to the single study applicants. Their answers would put the study branches in order of suitability, from the most to the least suitable ones for the applicants.
