Knowledge Discovery in Image Databases
Jaroš, Ondřej ; Řezníček, Ivo (referee) ; Chmelař, Petr (advisor)
This thesis is focused on knowledge discovery from databases, especially on methods of classification and prediction. These methods are described in detail. Furthermore, this work deals with multimedia databases and the way these databases store data. In particular, the method for processing low-level image and video data is described. The practical part of the thesis focuses on the implementation of this GMM method used for extracting low-level features of video data and images. In other parts, input data and tools, which the implemented method was compared with, are described. The last section focuses on experiments comparing extraction efficiency features of high-level attributes of low-level data and the methods implemented in selected classification tools LibSVM.

Textil Integrated Horn Antenna
Jaroš, Ondřej ; Pokorný, Michal (referee) ; Vélim, Jan (advisor)
This diploma thesis describes the corrugated substrate integrated horn antenna designed to surface wave’s excitation in the UWB band groups 3, 4, 5 and 6 (6 – 10 GHz). The antenna is integrated into 3,4 mm thick textile with relative permittivity r = 1,195. The coaxial cable is connected via the SMA connector that is attached to the aluminum bracket. From the microstrip line transition the corrugated substrate integrated waveguide is excited. Two strip lines are placed in front of the aperture for improvement of the impedance matching. The directivity of the antenna is 12 dBi at 8 GHz. At the same frequency, the antenna efficiency is 70%.

Family house in Sirákov
Jaroš, Ondřej ; Hofman, Petr (referee) ; Berková, Petra (advisor)
The aim of the thesis is the preparation of project documentation for construction of two-generation family house in the village Sirákov on plot number 2486/3. House located in steep terrain is suitable for housing up to two families. The building has a partial basement with a basement and two storeys. Part of the house is a garage for two cars. Fundamentals will be created from footing. The external walls are constructed of bricks Porotherm 30 Profi and insulated ETICS. Porotherm ceiling structure consists of joists POT and ceiling Miako. Inside the two-armed staircase is monolithic reinforced concrete. The roof cladding consists collar systems. On the gabled roof was elected concrete roofing Bramac.

Audio amplifier for detecting wood-destroying pests
Jaroš, Ondřej ; Křepelka, Pavel (referee) ; Friedl, Martin (advisor)
This bachelor´s thesis is focused on design of detector of wood-destroying pests, which is solved by using an acoustic sound source with piezo electric element as a sensor. The acquired signal is step by step amplified to a level when we can observe the audio spectrum using a headphone. The realized audio amplifier is complemented supplemented by an active analog filter for the ability to listen to a narrower frequency spectrum. The next feature of the detector is that it displays the frequency spectrum on an LCD display ranging from 0 Hz to 10 kHz. The spectrum of the signal is acquired by using DFT transformation. Analysis of the device is firstly described from the theoretical part through the realized design. At the end of document the results are summarized.

Knowledge Data Discovery
Jaroš, Ondřej ; Stryka, Lukáš (referee) ; Jurka, Pavel (advisor)
This Bachelor work describes knowledge data discovery. There are in detail described methods of data mining in this text. This work is focusing principally on Associative rules method of knowledge data discovery, applying Apriory algorithm. The purpose of this work was to implement chosen method and verify its functionality on particular sample of data. Application is implemented in Java programming language and the sample of data, used for our method, is saved in XML file. Application doesnt work with classic database, but with XML file. Information needed to run the program is loaded from input (system) XML document. Discovered data are saved to system XML document.

Wrestling in Physical Education in Primary School Teaching
Jaroš, Ondřej ; Štěpánek, Jan (advisor) ; Vejsada, Jindřich (referee)
Název práce: Zápas jako prostředek v rámci výuky na druhém stupni základních škol Název práce v angličtině: Using wrestling in physical education at primary school teaching Cíle práce: Zařadit prostředky úpolového sportu zápasu řecko - římského do běžné výuky vzdělávací oblasti tělesná výchova na druhém stupni základní školy Metoda: - analýza vzdělávacího programu, respektive rámcového vzdělávacího programu - pedagogický experiment - statistické zpracování dosažených výsledků - analýza dosažených výsledků Výsledky: Podporují myšlenku zavádění úpolových sportů do školních vzdělávacích programů v důsledku zvýšeného zájmů pubescentů o zvládání prků sebeobrany a zvyšování vlastní zdatnosti. Dosažené výsledky také upozorňují na stereotypní vedení hodin tělesné výchovy, kdy jsou nezřídka využívány pouze míčové hry a některé prvky atletiky. Klíčová slova: analýza, rámcový vzdělávací program, školní tělesná výchova, školní vzdělávací program, úpaly, zápas. 2
