Lossless Image Compression
Vondrášek, Petr ; Polok, Lukáš (referee) ; Bařina, David (advisor)
The aim of this master's thesis was to design, develop and test a method for lossless image compression. The theoretical part includes a description of selected exiting methods such as RLE, MTF, adaptive arithmetic coding, color models used in LOCO-I and JPEG 2000, predictors MED, GAP and laplacian pyramid. The conclusion includes a comparison of various combinations of chosen approaches and overall efficiency compared with PNG and JPEG-LS.

Study of optoelectrical properties of organic semiconductor thin film layers of phtalocyanines
Miklíková, Zdeňka ; Vala, Martin (referee) ; Zmeškal, Oldřich (advisor)
Diploma thesis is focused on the study of optoelectric properties of thin layers of organic materials based on phthalocyanines, which can be used as an active layer of photovoltaic cells. Especially are studied the properties of the thin active layers of PdPc and PdPc + IL on the glass or ceramic substrates with aluminium contact, which are prepared by material printing here. On the prepared samples were first measured current-voltage characteristics in the dark and in the light and then were measured impedance spectrums in the dark. The received results will be used to improve the properties and structures of photovoltaic cells.

Multifunctional Building Brno
Arletová, Hana ; Saktor, Igor (referee) ; Saktor, Igor (referee) ; Menšíková, Naděžda (advisor) ; Šuhajda, Karel (advisor)
Residetial house is located in the street Milady Horákové in Brno city center. In this street are some historically listed buildings. Next to the gap is a residential house designed by Josef Müller. These buildings influenced the appearance of design buildings though, there is a new poly-functional building from Dobrý dům s.r.o.. The most important element of the building are high windows which harmonize with old structure. On the facade is an art element made by different composition of bricks. It is in front of the part of the windows and let the sun go to the interior and the wall slowly pass to the window. Residetial building has 8. floors. On the first floor is a passage. On the first and the second floor is designed a shop. On the second floor is also a small flat. On the other floor are flats. On the last floors there are two duplex flats. Parking is provide by automatic parking system. The residential buildings is characterized by connection old materials and new technologies. It presents the evolution of architecture in the street.

Famili House
Bittman, Jaroslav ; Hubáček,, Petr (referee) ; Hubáčková, Blažena (advisor)
The aim of Bachelor’s work ,, Family house '' is drawing of project documentation for realization progress. Detached house will be used by 4 member family. It’s situated in Brno – Židenice. It will be built in a gap, between two houses located in Otakara Ševčíka street. It has 3 ground floors. Bearing walls are made of ceramic brick block Porotherm. The ceilings are made of POT beams and ceramics liners MIAKO. Gabled roof is covered with smooth sheet.

Experimental assessment of the role of biotic interactions in community species pool delimitation
ŠVAMBERKOVÁ, Eva
Seed addition experiment was conducted on the moisture gradient with aim to demonstrate that many species not accounted by current measures of species pools in a site should be included because they are in fact able to establish successfully if biotic filter is removed. Transplant experiment was established to compare the sensitivity of seedling recruitment and survival of transplants in the field. Recruitment of seedlings in field was observed and compared with germination of seeds under different chilling treatments in laboratory.

Measurement and evaluation of emission gas production in the selected operation with castle and design to reduce them.
KOLÁŘ, Kamil
This thesis deals with the pollution of the environment (atmosphere, hydrosphere and pedosphere) greenhouse gases and ammonia from agricultural livestock. Globally, agriculture is considered absolutely largest producer of ammonia. The work deals with good agricultural practice, the stable microclimate and overall welfare. Custom work is focused on measuring and determining the concentration of gaseous emissions of carbon dioxide, nitrous oxide, methane, ammonia and water vapor. The measurement was carried out in the barn with a meat breed Charolais farm SEVAL in Valdov. For the measurement of exhaust gas was used device company INNOVA. Further, there are proposals include funds for reducing gas emissions.

PIC simulace pravoúhlých a seříznutých štěrbin ve zkušebním limiteru tokamaku TEXTOR
Komm, M. ; Pekarek, Z. ; Pánek, Radomír ; Matveev, D. ; Kirschner, A. ; Litnovsky, A.
In this paper, we present results of Particle-In-Cell simulations of the plasma behavior in the vicinity of gaps in castellated plasma-facing components. We studied gaps in the test limiter of TEXTOR, which is a plasma-facing component designed for studies of impurity transport and fuel retention, mainly via hydrocarbon layer formation. The castellated limiter tiles have been analyzed using the postmortem techniques and first attempts of impurity transport modelling were done using the 3DGAP code [Matveev et al., 2008]. In order to improve the agreement between modeling and experiment, realistic plasma particle flux distribution needs to be included in the code. For this purpose, a series of PIC simulations for varying plasma conditions was performed by using the SPICE2 code [Dejarnac et al., 2008]. Plasma behavior inside the gaps is discussed and semi-empiric characterization via generic fitting procedure is proposed

New approaches to construction of vehicles insurance
Čápová, Markéta ; Ducháčková, Eva (advisor) ; Daňhel, Jaroslav (referee)
This thesis describes new possibilities that can occur at construction of motor-vehicle insurance on the worldwide market. In Czech republic there has been insurance liability for damage incurred running vehicles and wrecking crane insurance till now. Abroad indeed begins extend unprecedented product of motor-vehicle insurance known as Pay As You Drive that derives benefits from absolutely new methods at construction insurance.Insurance is invoiced on the basis of real mileage.For data gathering there are exploited different counter circuit functional mainly on the basis of GPS navigation.Aim of diploma work was analysis of this new kind of insurance, evaluation of its fruitfulness, serviceability and possibilities of its aplication in Czech republic.At the end of my thesis there was effected analysis of GAP insurance that can be negotiate in Czech republic already. GAP Insurance there has been like form of additional insurance to all-risk insurance. It covers difference in acquisition price of new vehicle and its actual market price that the classical all-risk insurance doesn't cover.
