A Microscopia Eletrônica de Baixa Energia (LEEM) é uma recente e poderosa modalidade para o estudo de superfície passível de uma grande quantidade de degradações, como ruídos e borramento. Ainda incipiente na literatura, este trabalho visou a análise e identificação das fontes de degradações presentes em vídeos, além da utilização de um conjunto de técnicas de remoção de ruído e borramento para a restauração de dados LEEM. Além disso, foram desenvolvidas duas novas técnicas de filtragem de vídeo como intuito de preservar detalhes pequenos e texturas presentes. Na etapa de análise foi constatado que as imagens LEEM possuem uma grande quantidade e variedade de ruídos, sendo o Gaussiano o mais preponderante. Foi também estimada a Função de Espalhamento de Ponto (PSF) do microscópio utilizado, visando o emprego de técnicas de redução de borramento. Este trabalho também analisou a combinação de técnicas de redução de borramento com as técnicas de filtragem do ruído Gaussiano existente. Foi constatado que as técnicas não locais, como Non-Local Means (NLM) eBlock-Matching 3-D (BM3D), proveem uma maior capacidade de filtragem das imagens LEEM, preservando descontinuidades. Ainda nesta análise, identificou-se que algumas técnicas de redução de borramento não são efetivas em imagens LEEM, exceto a técnica Richardson-Lucy (RL) que suprimiu grande parte do borramento sem adicionar mais degradação. A indesejável remoção de pequenas estruturas e texturas pelas técnicas de filtragem existentes motivou o desenvolvimento de duas novas técnicas de filtragem de ruído Gaussiano (NLM3D-LBP-MSB eNLM3D-LBP-Adaptive) que mostraram resultados superiores para filtragem de imagens com grande quantidade de textura. Porém, em imagens com muitas regiões homogêneas o BM3D foi superior. Avaliações quantitativas foram realizadas sobre imagens artificiais. Em imagens LEEM reais, realizou-se um experimento qualitativo em que observadores avaliaram visualmente o resultado de restaurações por diversas técnicas existentes e as propostas neste trabalho. O experimento comprovou que os métodos de filtragem não locais foram superiores, principalmente quando combinados com o método RL. Os métodos propostos produziram bons resultados, entretanto, inferiores aos exibidos pelas técnicas NLM eBM3D. Este trabalho demonstrou que as técnicas de filtragem não locais são as mais adequadas para dados LEEM. Além disso, a técnica RL mostrou-se eficaz na redução de borramento. / Low Energy Electronic Microscopy (LEEM) is a recent and powerful surface science image modality prone to considerable amounts of degradations, such as noise and blurring. Still not fully addressed in the literature, this worked aimed at analysing and identifying the sources of degradation in LEEM videos, as well as the adequacy of existing noise reduction and deblurring techniques for LEEM data. This work also presented two new noise reduction techniques aimed at preserving texture and small details. Our analysis has revealed that LEEM images exhibit a large amount and variety of noises, with Gaussian noise being the most frequent. To handle the deblurring issue, the Point Spread Function (PSF) for the microscopeused in the experiments has also been estimated. This work has also studied the combination of deblurring and denoising techniques for Gaussian noise. Results have shown that non-local techniques such as Non-Local Means (NLM) and Block-Matching 3-D (BM3D) are more adequate for filtering LEEM images, while preserving discontinuities. We have also shown that some deblurring techniques are not suitable for LEEM images, except the RichardsonLucy (RL) approach which coped with most of the blur without the addition of extra degradation. The undesirable removal of small structures and texture by the existing denoising techniques encouraged the development of two novel Gaussian denoising techniques (NLM3D-LBP-MSB and NLM3D-LBP-Adaptive) which exhibited good results for images with a large amount of texture. However, BM3D was superior for images with large homogeneous regions. Quantitative experiments have been carried out for synthetic images. For real LEEM images, a qualitative analysis has been conducted in which observers visually assessed restoration results for existing techniques and also the two proposed ones. This experiment has shown that non-local denoising methodswere superior, especially when combined with theRL method. The proposed methods produced good results, but were out performed by NLM and BM3D. This work has shown that non-local denoising techniques are more adequate for LEEM data. Also, theRL technique is very efficient for deblurring purposes.

Internet of Things is the latest phenomenon in the computing industry. Even if it has not been completely defined yet, we are already surrounded by various devices connected to the Internet. This thesis project focuses on low cost and low-power wireless solutions and on the on-line backend behind the architecture. At the same time the present work also deals with Cloud Computing which can provide a highly scalable runtime environment for this backend without building an infrastructure. To handle the huge amount of data collected by billions of devices, BigData services could be used in the same cloud space. The project is a collection of the theoretical background of the Internet of Things; so as a result, it provides the reader with an overview of the concept. It also provides a walktrough of the design, implementation and testing process of a complex agricultural Internet of Things solution.

Presented theses dealing with the complex influence of human activity on the environment. Particularly provides the calculation of carbon footprint volume consumed during manufacturing of raw materials used for a normal and a low-energy house. The calculation of the energy performance certificate for both variants is also included. To evaluate of economical demanding investment to both mentioned houses including carbon dioxide disposal, the theoretical calculation of the price of carbon footprint equivalent has to be determined. The aim of this study is an investigation of carbon footprint in construction industry focusing on the production of carbon dioxide during the realization of a normal and low-energy house.

The theme of the diploma thesis is the study of physical properties of various building materials in buildings in low-energy construction. The work is mainly focused on the influence of the thermal accumulation properties of building materials used in buildings in order to achieve low energy consumption for heating. The thesis compares the energy characteristics of five different constructional material variants of the house.

Uměle vytvořené systémy spinového ledu jsou vhodným nástrojem pro zkoumání neobvyklých jevů, které se v přírodě dají jen těžko pozorovat. Speciálním případem umělého spinového ledu je kagome mřížka, která umožňuje zkoumat kolektivní chování spinů v látce. Tento systém má řadu předpovězených exotických magnetických fází, které zatím nebyly změřeny a prozkoumány v reálném prostoru. V rámci této práce se zabýváme úpravou kagome mřížky tak, aby mohla být využita ke zkoumání exotických stavů v reálném prostoru. Experimenty provedené na naší upravené mřížce ukazují, že jsme schopni detekovat nízko i vysoko energiové stavy, a tedy, že námi navržená úprava kagome mřížky je vhodná pro zkoumání exotických stavů v reálném prostoru.

This thesis focuses on the Internet of Things and some of the most important problems it faces today. Among these are the overdependence on the Cloud and lack of autonomy, poor security and privacy, complicated initialization and power consumption. The work aims to implement a complex IoT solution that solves the discussed problems. The project is part of a collaboration with NXP Semicondutors and will be used to showcase the company's technologies.

The project documentation, processed in the framework of the diploma thesis, solves the new building of the multifunctional house in Žďár nad Sázavou. The building is made of traditional brick technology of brick fittings, with insulation, ceilings are reinforced concrete monolithic, roof sloping in two variants. Commercial premises are located on the ground floor on the south side. Furthermore, on the floor there are technical facilities for offices and storage space for housing units and offices. On the next floors there are always 3 residential units. The building is located on flat terrain in the rapidly developing part of the city. The building envelope and individu-al structures are designed to the entire object it was as energy- consuming as possible, and do not pump irreparably by nature its natural resources in a larger quantity than necessary.
