The theoretical part focuses on the formation, transport of solar radiation and its availability in the Czech Republic. There are also discussed solar thermal systems and components of these systems, including their use. Project part addresses two design options of heating the hotel building. The first version is aimed at the common solution in the form of heating radiators with the source in the form of gas boiler and solar hot water. The second option solves superior solutions in the form of heating and cooling ceilings in the form of heat source heat pumps and solar heating support. Experimental solutions are focused on monitoring the operational status of the experimental solar devices and evaluation of operating characteristics of the device.

Les météorites et particules de poussière interplanétaire apportent des contraintes sur la formation et l’évolution de la matière dans le système solaire. Les micrométéorites, dont certaines proviennent des régions externes du système solaire, représentent la source dominante de matière extraterrestre arrivant sur Terre. Les micrométéorites collectées dans les neiges antarctiques sont dans un excellent état de conservation du fait de conditions géographiques et météorologiques favorables à leur préservation. La collection CONCORDIA/CSNSM de micrométéorites contient en particulier des micrométéorites peu altérées thermiquement lors de leur entrée atmosphérique. Certaines sont caractérisées par une très haute teneur en matière organique, dépassant 50% en volume, très largement au dessus des valeurs habituelles trouvées dans les météorites. Cette matière organique présente de plus la spécificité d’être fortement enrichie en deutérium et contient jusqu’à cinq fois plus d’azote celle extraite des météorites.Les différents scénarios proposés pour expliquer la formation de cette matière et satisfaisant à l’ensemble des caractéristiques de ces micrométéorites impliquent des corps parents orbitant au-delà de Neptune, dans la ceinture de Kuiper ou dans le nuage de Oort. La température y est suffisamment basse pour condenser à leur surface les molécules volatiles comme l’azote et le méthane tandis qu’ils sont exposés à l’action radiochimique du rayonnement cosmique galactique. Afin de contraindre ces scénarios, des expériences ont été conduites en exposant différentes glaces N2-CH4 aux faisceaux d’ions du GANIL simulant ce rayonnement. L’évolution chimique des glaces au cours de l’irradiation et pendant le recuit des échantillons a été suivie par spectroscopie infrarouge au moyen de deux dispositifs disponibles au CIMAP : la chambre d’analyse CASIMIR et le nouvel appareil IGLIAS. Des analyses complémentaires ex situ ont été menées par spectrométrie de masse. Les résultats apportant des éléments de réponse à l’origine de la matière organique des micrométéorites ultracarbonées ainsi que sur l’origine de leur enrichissement isotopique seront présentés et discutés. / Extraterrestrial materials, such as meteorites and interplanetary dust particles, provide constraints on the formation and evolution of organic matter in the young solar system. Micrometeorites represent the dominant source of extraterrestrial matter at the Earth’s surface, some of them originating from large heliocentric distances.Micrometeorites recovered from Antarctica snows provide a unique source of pristine interplanetary dust particles, which underwent a minimal weathering at atmospheric entry. A few percent are characterized by very large carbon content with at least 50% in volume, much higher than the value found in meteorites. This organic matter exhibits extreme deuterium excesses and is unusually nitrogen-rich.Several formation scenarios have been proposed for the formation of the N-rich organic matter observed in UCAMMs, suggesting that these particles come from a parent body orbiting beyond the nitrogen snow line, in the outer Solar System where they are exposed to ions from the galactic cosmic rays. We experimentally evaluate the scenario involving high energy irradiation of icy bodies subsurface orbiting at large heliocentric distances by irradiating N2-CH4 ices with swift heavy ions provided by the GANIL facility. Chemical evolution was monitored by Fourier transform infrared spectroscopy with two experimental set-up : CASIMIR and IGLIAS. Ex situ mass spectroscopy measurement where also conducted. Results concerning the origin of the organic matter found in ultracarbonaceous micrometeorites and the origin of its deuterium enrichment will be presented and discussed.

In August, 2014 three experiments were conducted using infrared systems deployed at White Mountain Research center, CA. The data was acquired for the whole month of August. Teams of 3-4 students from Cal Poly San Luis Obispo and UC Santa Barbara were stationed at the research center for 2-3 days to operate the equipment. The three experiments were:(1) creating spatial-temporal time series of lunar surface temperatures;(2) identifying atmospheric meteor trails;(3) search for meteor impacts on the Moon surface. Out of the three this thesis focusses on experiment 1 and the results from this experiment could also help with the other experiments. We propose to use a thermal infrared camera mounted on a telescope to acquire time-series observations of lunar surface temperatures to get a novel insight into the thermal evolution of the Moon over a complete lunar cycle. Half a lunar cycle would account from morning to night and lasts for approximately 14.75 days. Seeing how the pixel value changes from morning to night the pixel and temperature trends can be observed throughout the day. Apart from that one can get the two temperature peaks that could maybe help to get an estimate for the Thermal inertia of the surface in the presence of Moon regolith. The temperature trends and the thermal inertia could potentially provide some insight for methods that seek to determine the properties of asteroids from ground based observations.

Thesis: Ph. D., Joint Program in Oceanography/Applied Ocean Science and Engineering (Massachusetts Institute of Technology, Department of Earth, Atmospheric, and Planetary Sciences; and the Woods Hole Oceanographic Institution), 2018. / Cataloged from PDF version of thesis. / Includes bibliographical references. / This thesis investigates the timing and source(s) of water and volatile elements to the inner solar system by studying the basaltic meteorites angrites and eucrites. In chapters 2 and 3, I present the results from angrite meteorites. Chapter 2 examines the water and volatile element content of the angrite parent body and I suggest that some water and other volatile elements accreted to inner solar system bodies by ~2 Myr after the start of the solar system. Chapter 3 examines the D/H of this water and I suggest it is derived from carbonaceous chondrites. Chapter 4, 5, 6, and 7 addresses eucrite meteorites. Chapter 4 expands on existing models to explain geochemical trends observed in eucrites. In Chapter 5, I examine the water and F content of the eucrite parent body, 4 Vesta. In chapter 6, I determine the source of water for 4 Vesta and determine that carbonaceous chondrites delivered water to this body. Chapter 7 discusses degassing on 4 Vesta while it was forming. / by Adam Robert Sarafian. / Ph. D.

This work involves preparing a basis for the company Riksbyggen AB and the housing association Brf ASEA-Stan for a possible installation of solar panels on their apartment building on Relävägen 5 (722 24) Västerås. As the company has already installed solar cells on other apartment buildings, a comparison will also be made between the various apartment buildings and what it means in terms of production to install solar cells on Relävägen 5 (722 24) in Västerås. Payoff time and the placement of the solar panels are further factors that have been taken into consideration when designing the solar system at Relävägen 5. From the results a conclusion was made that the apartment building electrical usage may be affected positively by an installation of solar panels. This is because in the summer the building can be self-sufficient while in the winter the building won’t need to buy as much electricity even though the sun hours are very low. The slope of the solar cell system is crucial for the electricity production for an apartment building, which reflects the work’s comparison of the slope and its differences. Interviews, study visits and simulation programs are examples of methods used during the work to facilitate the design of the solar cell system.

Determining mafic mineral composition of asteroid bodies is a topic reviewed by M.J. Gaffey et al. (2002). The iterative procedure discussed can be implemented as an algorithm, and such efforts revealed weaknesses that are examined in this work. We seek to illustrate the limits of this method and graphically determine its predictions. There are boundaries in the formulae given where the equations break down. In ranges where mafic mixtures are predicted, a method is illustrated that allows a decoupling of these mixtures into the constituents.

[pt] Nos últimos anos foi registrado crescimento no consumo energético dos edifícios residenciais, fato marcado pela aceleração gradual do aquecimento global e pelo declínio econômico e ambiental. A eficiência energética vem se apresentando como um vetor estratégico para a sustentabilidade e economia. As tecnologias e a dependência da energia cresceram exponencialmente nos últimos anos, por isso, o tema foi ganhando mais força e atraindo mais consumidores, pois a dependência da população era cada vez maior e não estava sendo acompanhada economicamente. Portanto, essa dissertação tem o objetivo de fomentar através de uma revisão bibliográfica, o progresso da introdução de ações de sustentabilidade na construção. Na presente dissertação são estudadas algumas medidas para ser implementar em um condomínio já existente, localizados no bairro da Tijuca, em Rio de Janeiro, de forma a reduzir consumos energéticos nas áreas comuns dos dois prédios. Foi apresentada uma solução para a produção de energia elétrica a partir de um sistema solar fotovoltaico do tipo On-Grid, analisando o custo de implantação deste sistema, bem como o tempo de retorno do investimento, para finalmente, chegarmos à conclusão sobre a viabilidade da implantação. / [en] Sustainability in the construction sector has gained significant attention in recent years, as the industry recognizes the need for greener and more socially responsible practices. This paradigm shift stems from the understanding that construction activities have a substantial impact on the environment, consuming large amounts of energy, water and raw materials, while generating significant amounts of waste and carbon emissions. To meet these challenges, sustainable construction aims to minimize negative environmental and social impacts throughout a building s life cycle. Incorporating sustainability principles into the construction sector involves several key elements, such as energy efficiency, which plays a key role in sustainable construction. Photovoltaic solar energy aims to minimize dependence on non-renewable energy and reduce greenhouse gas emissions. In conclusion, sustainability in the construction sector involves integrating environmentally responsible practices into all stages of a building s life cycle. The energy performance of buildings has become a concern in Brazil, increasingly focused on sustainability and renewable energy, this concept refers to the measurement of a building s energy efficiency. With energy consumption and greenhouse gas emissions on the rise, it is imperative to assess and improve a building s energy performance in order to mitigate the negative consequences of climate change and reduce the building s energy bills. Several international standards and certifications, such as LEED (Leadership in Energy and Environmental Design) or BREEAM (Building Research Establishment Environmental Assessment Method), provide frameworks for assessing and certifying the energy performance of buildings. These programs emphasize sustainable design, energy efficiency and the reduction of environmental impact, improving the energy and environmental sustainability aspects of buildings. In conclusion, the energy performance of buildings is a critical aspect of achieving sustainability goals and mitigating climate change. Implementing energy-saving measures and adhering to international standards and certifications can lead to improved energy performance and reduced environmental impact.

<p>Magnetized planets, such as Earth, are strongly influenced by the solar wind. The Sun is very dynamic, releasing varying amounts of energy, resulting in a fluctuating energy and momentum exchange between the solar wind and planetary magnetospheres. The efficiency of this coupling is thought to be controlled by magnetic reconnection occurring at the boundary between solar wind and planetary magnetic fields. One of the main tasks in space physics research is to increase the understanding of this coupling between the Sun and other solar system bodies. Perhaps the most important aspect regards the transfer of energy from the solar wind to the terrestrial magnetosphere as this is the main source for driving plasma processes in the magnetosphere-ionosphere system. This may also have a direct practical influence on our life here on Earth as it is responsible for Space Weather effects. In this thesis I investigate both the global scale of the varying solar-terrestrial coupling and local phenomena in more detail. I use mainly the European Space Agency Cluster mission which provide unprecedented three-dimensional observations via its formation of four identical spacecraft. The Cluster data are complimented with observations from a broad range of instruments both onboard spacecraft and from groundbased magnetometers and radars.</p><p>A period of very strong solar driving in late October 2003 is investigated. We show that some of the strongest substorms in the history of magnetic recordings were triggered by pressure pulses impacting a quasi-stable magnetosphere. We make for the first time direct estimates of the local energy flow into the magnetotail using Cluster measurements. Observational estimates suggest a good energy balance between the magnetosphere-ionosphere system while empirical proxies seem to suffer from over/under estimations during such extreme conditions.</p><p>Another period of extreme interplanetary conditions give rise to accelerated flows along the magnetopause which could account for an enhanced energy coupling between the solar wind and the magnetosphere. We discuss whether such conditions could explain the simultaneous observation of a large auroral spiral across the polar cap.</p><p>Contrary to extreme conditions the energy conversion across the dayside magnetopause has been estimated during an extended period of steady interplanetary conditions. A new method to determine the rate at which reconnection occurs is described that utilizes the magnitude of the local energy conversion from Cluster. The observations show a varying reconnection rate which support the previous interpretation that reconnection is continuous but its rate is modulated.</p><p>Finally, we compare local energy estimates from Cluster with a global magnetohydrodynamic simulation. The results show that the observations are reliably reproduced by the model and may be used to validate and scale global magnetohydrodynamic models.</p>

The last twenty-five years have seen our understanding of the formation and abundance of planets revolutionised, thanks to the first detections of debris discs, and, a decade later, of the first extrasolar planets. Hardly a week now goes by without a planet discovery, and the range of methods used to search for planets has expanded to include techniques that are efficient at detecting different types of planets. By combining the discoveries of the various methods, we therefore have the opportunity to build a picture of planet populations across the Galaxy. In this thesis, I am presenting work done as a basis towards such an effort: first I present work carried out to improve modelling methods for gravitational microlensing events. Since the first microlensing observing campaigns, the amount of data of anomalous events has been increasing ever faster, meaning that the time required to model all observed anomalous events is putting a strain on available human and computational resources. I present work to develop a method to fit anomalous microlensing events automatically and show that it is possible to conduct a thorough and unbiased search of the parameter space, illustrating this by analysing an event from the 2007 observing season. I then discuss the possible models found with this method for this event, and their implication (Kains et al. 2009), and find that this algorithm locates good-fit models in regions of parameters that would have been very unlikely to be found using standard modelling methods. Results indicate that it is necessary to use a full Bayesian approach, in order to include prior information on the parameters. I discuss the analytical priors calculated by Cassan et al. (2009) and suggest a possible form of an automatic fitting algorithm by incorporating these priors in the algorithm used by Kains et al. (2009). Another topic with which this thesis is concerned is the evolution of debris discs around solar-type stars. Late-type stars are expected to be the most numerous host stars of planets detected with the microlensing technique. Understanding how their debris discs evolve equates to understanding the earliest stages of planet formation around these stars, allowing us to truly put our Solar System in perspective. Using the analytical model of Wyatt et al. (2007a), I modelled the evolution of infrared excess flux at 24 and 70 microns using published data of debris discs around solar-type (spectral types F, G and K) stars from the Spitzer Space Telescope. By comparing the results of this study to an analogous study carried out by for A stars by Wyatt et al. (2007b), I find that although best-fit parameters are significantly different for solar-type stars, this may be due to the varying number of inefficient emitters around stars of different spectral types. I suggest that although effective properties are different by an order of magnitude or more, intrinsic properties, while still different, are so by a much smaller factor. These differences may be due to the longer timescales over which solar-type stars evolve, which allow for the formation of larger and stronger planetesimals.

Abstract INTERDISCIPLINARY CONNECTIONS BETWEEN SCIENCE & THEATRE Jessica Nicole Dotson A thesis submitted in partial fulfillment of the requirements for the degree of Master of Fine Arts at Virginia Commonwealth University. Virginia Commonwealth University, 2015. Major Director: Dr. Noreen C. Barnes, Director of Graduate Studies, Associate Professor of Theatre In the 1990s, astronomer Peter Usher was searching for new ways to teach his introductory astronomy class at Pennsylvania State University. He began to engage his students by searching for astronomical connections from other disciplines. His focus was turned to the arts, especially the works of William Shakespeare. Usher found, while searching through the canon of Shakespeare's work, astronomical references that explored the “new astronomy” of the Elizabethan age (Falk 171). This thesis will explore the writings of Usher, in regard to the astronomy of Hamlet, along with the interdisciplinary connections between art and science in and outside the classroom and museum theatre. From interdisciplinary classroom methods, to arts and scientists collaborating together for the betterment of man-kind, the use of theatre is a way of rediscovering the humanity of human history. The collaboration between the disciplines serves as one of theatre's greatest purposes, to educate and represent a living history of man.
