Automatic improvements of images from 1D gel electrophoresis
Kovář, Martin ; Vítek, Martin (referee) ; Škutková, Helena (advisor)
In this bachelor’s thesis are explained the basic principles of electrophoresis and its modalities with focusing on 1D gel electrophoresis. It describes analysis of an electrophoreogram and causes of its possible distortion, and states specifications of applications of the method in microbiology, genomics and proteomics. The practical part presents development, optimization and outputs of a programme for automatic electrophoreogram analysis, which was created in Matlab environment. The analysis contains lane and band detection and computation of samples’ molecular weight. The ending of the thesis is constituted by evaluating efficiency of detection and accuracy of weight computation.

Development of Operating System Based on Evolutionary and Genetic Algorithms
Skorkovský, Petr ; Moučka,, Jiří (referee) ; Kovár, Martin (referee) ; Chvalina, Jan (advisor)
The main goal of the work is to introduce new ideas how traditional approaches for designing an operation system and associated software can be improved to be a part of automatic software evolution. It is generally supposed that algorithms found by the genetic programming processes cannot be used for exact calculations but only for approximate solutions. Several examples of software evolution are introduced, to show that quite precise solutions can be achieved. To reach this goal, characteristics of tree-like structures with approaches based on cellular automata features are combined in a new promising technique of algorithm representation, joining benefits of both concepts. An application has been developed based on these new genetic programming concepts and it is supposed it can be a part of a future automatic software evolution process.

Realization of fingerprint scanner
Kovář, Martin ; Sekora, Jiří (referee) ; Mézl, Martin (advisor)
This master’s thesis deals with the issue of scanning human fingerprints, which is currently very topical and represents the most widespread biometric technology. The theoretical part of the work acquaints the reader with basics of dactyloscopy and biometrics and concerns technologies used for fingerprinting, image preprocessing methods and commercially available contactless optical scanners. The practical part is a realisation of a contactless optical scanner based on a Raspberry Pi minicomputer, implementation of preprocessing algorithms in Python and testing of the device from the perspective of image quality.

Electricity generation from biogas
Kovář, Martin ; Houdková, Lucie (referee) ; Pavlas, Martin (advisor)
The main goal of this bachelor thesis is an analysis and description of a combined production of thermal and electrical energy from biogas. Biogas belongs to the category of renewable energy. The first part is devoted to the biogas production. There are also described its properties and its comparison with other alternative fuels. The second part describes the principles of available cogeneration systems and their parameters. Design and analysis of a cogeneration system for a given biogas plan. Evaluation the economic aspect of cogeneration.

Environmentally advanced pension
Kovář, Martin ; Blasinski, Petr (referee) ; Horák, Petr (advisor)
The diploma thesis deals with the design of a new building of an environmental metal boarding house for the elderly with almost zero energy consumption. The guest house is a free-standing building with four floors and a middle tube, which is five floors. The first floor is more accessible to the public, there is a cafe, a social hall, offices, but also a nurse's office or technical facilities. The second to fourth floors are used for housing seniors in separate housing units. The total number of seniors who can stay here is 60. The first part of the documentation deals with the building permit for the construction in question. The entire object is made of a masonry ceramic system, which are horizontally interspersed with a monolithic ceiling slab. The facade on the first floor consists of wooden paneling, on the 2nd floor to the 4th floor there is already a facade plastered with silicone plaster. The roof structure consists of two different types, namely a walkable extensive green roof and an operational one with a roof rack. The second part of the work is focused on the engineering of the building environment, where concepts for the building's water supply were created. Furthermore, the concept of loading rainwater was solved, which is solved by a system of accumulation in a concrete sump with an overflow into a soaking device. The use of rainwater for irrigation or flushing is considered here. Heat pumps (ground / water) were chosen as a source of heating and cooling, which provide us with heat in the winter and cold in the summer. DHW is solved as an indirect heating tank, which is heated by the already mentioned heat pumps. In order for the object to meet all the requirements of today's building, we had to install forced ventilation or cooling of individual rooms for ideal thermal comfort in the summer. The concept of photovoltaic panels and the design of suitable lighting in individual rooms were also dealt with in the given part. The last part of the thesis dealt with the assessment of the source of heat and cold with regard to the consumed energy, acquisition and operating costs. The result of the given energy assessment should be the selection of a suitable source for the building in question. Sowtfare used in the work: Autocad 21, Archicad 25, Lumion, Altrea Duplex, AeroCAD, Deksoft, Microsoft Word, Microsoft Excel

Multifunctional building near little chapel - Židenice
Kovář, Martin ; Elešová, Klára (referee) ; Dulenčín, Juraj (advisor) ; Petříček, Tomáš (advisor)
The subject of my bechelor’s thesis is design of Multifunctional building in Brno – Židenice. Parcel is located in the corner of Táborská and Nezamyslova street, whitch dominates a small chapel. Size of object respects heigh of the adjacent buildings. Architecture composition based on contrast of cubic mass residential portion and dynamic mass with cafe. It also supports different color. By linking produces a harmonious whole dark strict, static and bright form in motion. Thanks to open residential wings in to the corner is posible to shine dispositiont of flats while insert mass of cafe maintain the boundary between public and private. Parking it is located in the underground floor. Parking is available by Autolift Each parking space it is done by parklifts for sixtteen cars. In the Ground floor is Cafe with hinterlands and Entraces of residential portion, there is entrance to the courtyard too. More floors above ground contains flats in size 2+kk and 3+kk.

Cathedral today
Kovář, Martin ; Mléčka, Jan (referee) ; Štěpán, Marek (advisor)
The content of the work is ideas solution for the roof of the Notre-Dame in Paris, after the destroying fire in 2019. Main idea is to create garret space for spiritual people, which used to meet, study and pray without the contact with the tourists and fill in the gap after the old tower above the crossing. Concept based on the original garret, which was only for service. The idea is coming especially from the simplicity and effectivity of the old garret and pointing on some of his elements. Space under the roof should be simple according to the first floor of the cathedral. The function is reflecting simplicity of the spaces with the respect to historical cathedral. Garret is designed for spiritual people, who are working in Notre-Dame and makes a space for them, which will be calm place for meditation. For this purpose are there cells for individual studying, library, common space and chapel. Connecting and meeting point in the same time between the ground, garett and higher power is sanctuary. This part is getting light to the ground floor.

CO2 removing from biogas
Kovář, Martin ; Niesner, Jakub (referee) ; Dvořák, Radek (advisor)
Research the Selexol, Rectisol, Fluor and Purisol technologies for the treatment of biogas to natural gas quality is the main job. The purified biogas must meet quality requirements, which sets out legislation Czech Republic. An important point is to build models of technology in the ChemCad software. Methods are analyzed with these models for the same output requirements. The result is to determine whether the technologies are suitable for biogas purification and implement, through research, simplified technical and economic evaluation.
