Automatic detection of ischemia in ECG
Noremberczyk, Adam ; Potočňák, Tomáš (referee) ; Ronzhina, Marina (advisor)
This thesis discusses the utilization of the artificial neural networks (ANN) for detection of coronary artery disease (CAD) in frequency area. The first part of this thesis is orientated towards the theoretical knowledge. Describes the issue of ECG pathological changes. ECQ are converted to frequency area. Described statistical methods and methods for automatic detection of CAD and MI. Explained the issue of the perceptron and ANN. The second deals with use of Neural Network Toolbox MATLAB®. This part focuses on counting and finding suitable parameters and making connection of band. At the end of the thesis UNS is used to detect ischemic parameters and the results are discussed. Average values for the best settings are 100% accuracy.

Study of the influence of magnetic fields on biological tissue
Vlachová Hutová, Eliška ; Fiala, Pavel (referee) ; Bartušek, Karel (advisor)
The aim of this research is to explore the influence of magnetic field on early somatic embryos (ESEs) of spruce and pine. The magnetic field is gradual. This is important for the experiment, each cluster of ESE was exposed to magnetic field of different intensity. The resulting report of this experiment consists of the comparison between various methods of image analysis and the difference in growth of ESEs due to different exposure to magnetic field and surrounding temperature. Enclosed is a proposal of ESE size computing algorithm from a given image.

Researching study of by-pass road of city Hustopeče
Tomešek, Zdeněk ; Kosňovský, Michal (advisor)
This graduation thesis deals about researching study of by-pass road of city Hustopeče, district of Břeclav, Southmoravian region. This city passes main road number 425, which should be connected with the by-pass road. The by-pass road will be designed as road of category S9,5/70 and will be situated west of the city. Terrain is undulated and composed of agricultural parcels. The main purpose of this by-pass road is significant burden of region traffic.

FROM EAST TO WEST: RELATIONS, COLLISIONS, AND DIVERGENCE OF CZECH AND JAPANESE CULTURE
Vaculík, David ; Čapková, Helena (referee) ; Mitášová, Monika (advisor)
The diploma thesis follows up the pre-diploma research dealing with the investigation of selected literature on Japanese traditional and modern architecture and gardens, archival research of extant 20th century buildings in Czech republic influenced by Czech-Japanese relations and the contemporary perception of Japan in the eyes of the Czech professional and uninitiated audience. It also includes a selective glossary of Japanese words and terms, containing study translations from English of selected architectural literature related to the topic. The output took the form of a Discovery Book with a short glossary, pictorial data and an anthology of translated texts. The thesis follows this preliminary "introductory research" with two main parts. The first part (A) explores concepts of space-making and spatial elements deeply rooted in Japanese traditional buildings as they were rediscovered and rethought, particularly by 20th century Japanese architects – who continued to use and revive these concepts in their own work. The text traces their understanding of Japanese traditional architecture. Then, using the example of three Japanese traditional spatial "icons", four works by 20th century Japanese architects, and three works by Czech architects in different phases of the 20th century, the thesis probes the relationship between these two architectural cultures in a European context. The second part (B) consists of texts on the architectural designing of model, utopian housing. The whole design follows a narrative – a scenario that shapes a temporal and spatial sequence that is not in line with the classical perception of time and space but spirals upwards. The next subsection interprets this story into spatio-temporal gradients and elements. Parts C and D contain conclusions and literature used. Model buildings are proposed on a range of scales: the smallest dwelling (a capsule), minimal dwelling, community dwelling, house, villa, city, and a coffin. The composition of the different scenarios and structures respects the movement along a spiral, where we can also observe the cyclical nature of life itself, which ends with the last terminal phase that escapes the gradient of scales – the coffin. These individual proposals are inspired by the studied phenomena and elements, texts and buildings of Japanese and European architecture with their interrelationships. The aim of this thesis is first to study the spatial, temporal, but also light and colour possibilities of Japanese traditional and modern architecture in the context of European, especially Czech, ones. Another aim is to propose a model-based, utopian housing project with a gradient layering of spaces, structures, materials, views and lighting based on various game strategies as well as the maxims of “Form follows fiction”.

The link-up of the Jihlava city Southeastern by-pass - transport junction of main road I/38 and major road II/523
Kozák, Petr ; Kutín, Ivan (referee) ; Smělý, Martin (advisor)
This diploma work deals with researching study of transport junction of main road I/38 and major road II/523 and than link-up of the proposed Outer ring road (VMO) and Southeastern by-pass (JVO) routes of region capital Jihlava, district of Jihlava, Vysočina region. Road structure will solve designed staged link-up of aboved mentioned roads according to their construction schedule. The design takes into account current roads and completed stages, with respect to minimum costs. Road structure is situated on Czech-Moravian Highlands. Its terrain is hilly, pondy and composed of agricultural parcels. The main purpose of this design is steady link-up of all considered traffic flows in the given locality.

Polymeric metamaterials with advanced mechanical properties
Štaffová, Martina ; Lehocký,, Marian (referee) ; Kotoul, Michal (referee) ; Jančář, Josef (advisor)
Práce se zabývá 3D tištěnými polymerními auxetickými strukturami s důrazem na jejich mechanické vlastnosti. Pro zlepšení mechanických vlastností, zejména poměru schopnosti absorpce energie k hmotnosti při tlakovém zatížení, byly použity různé návrhy auxetických re-entrantních struktur. Struktury byly vytištěny pomocí stereolitografické 3D tiskárny. Byl vyvinut a systematicky demonstrován nový nástroj pro komplexní charakterizaci 3D tištěných těles s využitím komerční fotopolymerizační pryskyřice s volnými radikály. Metoda se opírá o statický a oscilační mechanický test kombinující měření teploty průhybu při zatížení (HDT) s dynamickou mechanickou analýzou (DMA) v jediném testu pro rychlou a spolehlivou charakterizaci parametrů určujících chování fotopolymeru při vytvrzování. Byly zkoumány podmínky tisku a doba vytvrzení, aby byl objasněn jejich vliv na vnitřní napětí v 3D tištěných tělesech. Auxetické struktury byly vytištěny pomocí flexibilní a tuhé pryskyřice a byl zkoumán vliv poréznosti, velikosti buněk a strukturálních gradientů na mechanické vlastnosti. Výsledky byly vyhodnoceny z konstrukčního a materiálového hlediska pro fotopryskyřice nad a pod Tg. Nejlepší účinnost absorbování energie byla zjištěna u biaxiálně orientované struktury s nejvyšší lokální porozitou umístěnou ve středu. Prezentovaná data přispívají k základnímu pochopení účinků designu buněk na deformační odezvu auxetických struktur a mohou pomoct při návrhu nových struktur s lepšími mechanickými vlastnostmi. Výsledky zároveň demonstrují všestrannost 3D tisku při realizaci komplexních, přírodou inspirovaných struktur.

Konupka, Richard ; Šedivá, Soňa (referee) ; Beneš, Petr (advisor)
The bachelor’s thesis deals with problematics of confirmation of temperature shock chamber and methodology for its successful implementation. Theoretical part deals with brief overview of environmental test chambers used for testing temperature and humidity changes on tested samples. Bachelor’s thesis also deals with analysis of methodology for confirmation of temperature chambers according to the technical standard which will be partially used for methodology proposal of temperature shock chamber. Practical part of the thesis is gradually devoted to the measurement procedure proposal, where is discussed chosen temperature sensors and fixture of sensors in the chamber. Also proposed procedure of confirmation is shown, described measurements, calculation procedures, uncertainty estimations and at the end of the thesis are discussed results.
