The CubeSat Astronomy Network is a proposed system of multiple CubeSat spacecraft capable of performing follow-up observations of astronomical targets of interest. The system is intended to serve as a space-borne platform that can complement existing systems utilized for astronomical research by undergraduate and high school students. Much research and development work has been performed to develop model-based system engineering methodologies and products for CubeSat missions, including the Horizon Simulation Framework. The Horizon Simulation Framework enables the development of system models using the Extended Markup Language (XML), and its simulation program can generate system simulations over model-specified timespans. System requirements and constraints, as well as subsystem dependencies and functions, can also be directly specified in these models. Previous work using the framework has been performed to characterize “day-in-the-life” operations for Earth-observing spacecraft. A similar goal is intended for modeling the CubeSat Astronomy Network: simulating mission operations during nominal conditions to validate system and subsystem requirements. By developing this model, system and subsystem requirements derived in the course of preliminary design for the Network can be analyzed, modelled, and evaluated for feasibility. These results can then be used to inform design decisions related to system architecture and concept of operations at the early stages of design, while the models themselves can grow and mature alongside project development and be re-used for future design work.

This qualitative study is focused on young adult students’ experiences and perspectives of using websites for career information and guidance, and how that may impact their horizon of action in career decisions. Collection of data were made through interviews with college students from different faculties of Umeå University. All interviews were transcribed and compiled into various themes which were analysed with the perspectives of Digital literacy, Careership theory and the Chaos theory of careers. The result emergence the importance of students approaches on web-based information and their capacity of using it in their benefit. According to the student’s digital usage, which is categorized into simple and more advanced processes, perceives that digital literacy and personal characteristics may affect their use of career websites. The study concludes that internet is one of many social fields that influence the horizon of action and that the role of career websites depends on individual approaches and attitudes to several fields. For the work of career practitioners this study contributes with an insight about possibilities and risks that may come with student’s digital usage in career purpose. Therefore, this study also shows the requiring of further research in the area of career guidance and internet.

A novel approach to represent the profile of objects using Gaussian models is presented. The profile is a representation of the object and its surrounding regions. The object profile can be viewed as a comprehensive feature of that object and its surrounding regions. Different algorithms to estimate the profile are described. Geometric descriptors of the model are also proposed. The profile model is empirically shown to be effective and easily applicable to certain object recognition and segmentation tasks. Application experiments include modeling thin and thick objects as straight-lines, curves, and blobs using different primitives such as gray-level intensities, RGB, and HSV color. The datasets used for empirical validation are quite challenging. Datasets include images and videos corresponding to outdoor video, most of them with moving cameras. Some of the typical problems faced with the used datasets are: digital scaling, compression artifacts, camera jitter, weather effects, and cluttered backgrounds. We demonstrate the potential of leveraging the context of objects of interest as a part of an online detection process. Sample applications including detection of wires, sea horizon, street, and vehicles in outdoor videos are considered.

In the first part conceivable interpretation of the term, which is written more serious and argumentative tone, we view the horizon in several stops, which are based primarily on theories of art and Philosophy and carry the wave of post-modern methodology in style Umberto Eco. Didactic of DP indicates possible use as a theme for the term hours of art education, two of these ideas were implemented at Red Hill Primary School and are further detailed. In the end I tried to enter into a theoretical problem and evaluate show some benefits for my work. The practical part of the thesis is a series of paintings and drawings incurred in the last five years, and bear in themselves the poetic approach horitontu on a line that clearly separates our sometimes mundane lived world and spirituality, and sometimes disappear again behind a tangle of "objects" in which the But still somehow present.

Linhart, T: The borderline and the relationship to its surroundings. [Diploma thesis] Praha 2015 Charles University, Faculty of Education, Department of Art Education, 71 p. (Attachments on CD: 2 illustration attachments). The diploma thesis features a theoretical study on the background of the author's own artwork. The text interprets the borderline as a horizon that would emerge and vanish. It presents the author's own artistic grasp of the theme in context of selected trends in fine arts. Author seeks to define the boundary of fine arts and art education to establish a foundation to his own pedagogic determination. He shows what theoretical frameworks take part on shaping his own professional direction. The didactic part looks at select situations from the author's teaching practice that already took place and reflects them in context of author's other pedagogic experience. The accomplishment and utility of the work lie in a description and interpretation of select situations from practice of a fledgling teacher and an educational complex, field tested, intended for gymnasium students.

We examine the predictability of expected stock returns across horizons using machine learning. We use neural networks, and gradient boosted regression trees on the U.S. and international equity datasets. We find that predictabil- ity of returns using neural networks models decreases with longer forecasting horizon. We also document the profitability of long-short portfolios, which were created using predictions of cumulative returns at various horizons, be- fore and after accounting for transaction costs. There is a trade-off between higher transaction costs connected to frequent rebalancing and greater returns on shorter horizons. However, we show that increasing the forecasting hori- zon while matching the rebalancing period increases risk-adjusted returns after transaction cost for the U.S. We combine predictions of expected returns at multiple horizons using double-sorting and buy/hold spread, a turnover reduc- ing strategy. Using double sorts significantly increases profitability on the U.S. sample. Buy/hold spread portfolios have better risk-adjusted profitability in the U.S. JEL Classification G11, G12, G15, C55 Keywords Machine learning, asset pricing, horizon pre- dictability, anomalies Title Multi-horizon equity returns predictability via machine learning

After Deepwater Horizon oil reached the Florida coast, oil was buried in Pensacola Beach (PB) sands to ~ 70 cm depth, resulting in Total Petroleum Hydrocarbon (TPH) concentrations up to ~ 2 kg per meter of beach. This study followed the decomposition of the buried oil and the factors influencing its degradation. The abundance of bacteria in oiled sand increased by 2 orders of magnitude within one week after oil burial, while diversity decreased by ~ 50%. Half-lives of aliphatic and aromatic hydrocarbons reached 25 and 22 days, respectively. Aerobic microbial oil decomposition, promoted by tidal pumping, and human cleaning activities effectively removed oil from the beach. After one year, concentrations of GC-amenable hydrocarbons at PB were similar to those in the uncontaminated reference beach at St. George Island/FL, and microbial populations that disappeared after the oil contamination had reestablished. Yet, oxihydrocarbons can be found at PB to the present day.

En écho avec la réflexion de Gertrude Stein sur le théâtre, la présente thèse explore l’idée de paysage comme moteur, dissident de la trame d’une histoire, de l’action scénique et de l’émotion du spectateur. Quoique récurrente dans le discours théâtral actuel, l’association entre théâtre et paysage ne va pas de soi. Il y a là comme des « noces contre nature » entre deux règnes et deux échelles différentes : la scène théâtrale, règne du drame, bâtie poétiquement et architecturalement à l’échelle de l’homme, et le paysage, règne de la nature qui ne peut se concevoir qu’à l’échelle de l’infini. Des « noces contre nature » qui, pour être fécondes, exigent une double émancipation : celle de la paysagéité hors du cadre pictural d’où elle est née en même temps que celle de la dramaticité hors de la matrice aristotélicienne qui l’a forgée.En partant de l’étude du concept de paysage et de l’évolution du genre pictural paysager, la thèse cherche à mettre en perspective la façon dont la paysagéité s’est immiscée dans l’art théâtral. Dans le sillage du concept de pièce-paysage introduit par Gertrude Stein en 1934, l’écriture théâtrale contemporaine, libérée de la nécessité de raconter une histoire, convoque une scène mentale pour une action qui ne peut se projeter que dans l’espace infiniment petit et infiniment grand de la pensée. Cristallisant les intuitions dramaturgiques steiniennes, l’œuvre de Robert Wilson fonctionne comme un prisme à travers lequel s’affirme l’esthétique scénique paysagère: l’homme et sa parole sont décentrés au sein d’un espace qui s’ouvre vers l’horizon. On en trouve l’écho dans une série d’œuvres scéniques contemporaines – Claude Régy, Maguy Marin, Joël Pommerat, Heiner Goebbels, François Tanguy – qui déclinent à leur façon les critères esthétiques d’un spectacle-paysage que le théâtre de Robert Wilson aura permis de forger.Le devenir-paysage de la scène s’accomplit au prix d’un dépaysement du drame et de son spectateur. / The present thesis falls within Gertrude Stein’s legacy and explores the concept of landscape as a driving force of scenic action and audience emotion that is independent of the plot.Although it is now common in the theatrical discourse, the association between theatre and landscape is not a given one. It is a sort of “counter-natural alliance” between two different realms and scales. The stage, which belongs to the realm of theatre, is built both poetically and architecturally to the human scale, whereas a landscape, which belongs to the realm of nature, can only be conceived of on an infinite scale. This “counter-natural alliance” can only be fertile if two emancipations occur: that of the landscape from the pictorial frame from which it was born, and that of drama from the Aristotelian matrix which constructed it.The thesis starts from a study of the evolution of the pictorial genre of the landscape and the concept of the same to examine how it infiltrated theatrical art. Contemporary theatrical writing followed in the footsteps of Gertrude Stein’s concept of the landscape play introduced in 1934 and was free of the necessity to tell a story. It conjures up a mental stage for actions which can only be envisaged in the infinitely small and infinitely large spaces of thought.Robert Wilson’s work crystallized Stein’s dramaturgic intuitions. It acted as a prism through which the stage esthetics of landscape was focused; therein, man and speech are decentralized within a space which opens towards the horizon. Many contemporary scenic works echo this, including those of Claude Régy, Maguy Marin, Joël Pommerat, Heiner Goebbels and François Tanguy, who play with the esthetic criteria of the landscape play which Robert Wilson’s work initially forged.The stage becomes a landscape through the disorientation of drama and its audience.

Piezoelectric materials have had widespread application since their discovery both in bulk crystal and thin film applications, but thin film piezoelectrics have unlocked key applications like acoustic filtering and energy harvesting. [1] This work investigates a small subset including energy harvesting, multifunctional nanocomposites, acoustic wave resonators, and gravimetric and infrared sensing. Electroactive polymers such as PVDF-TrFE have a unique combination of characteristics including a high dielectric constant, piezoelectricity, pyroelectricity, biocompatibility, and mechanical flexibility. [2, 3, 4, 5, 6] This unique combination gives them a wide potential application space including energy harvesting, biomedical devices, drug delivery, flexible electronics, and tactile sensing. [7] In recent years, there has been significant work investigating potential composite materials based on electroactive polymers and nanoparticles. [8] This interest has been primarily driven by the increased commercial availability, tunability, and available functionalities of nanoparticles. In this work, nanocomposites of PVDF-TrFE, barium titanate (BTO), and europium barium titanate (EBTO) are investigated. EBTO is an optically active material which can add optical functionality to these active polymer composites. [9] Acoustic wave resonators including bulk acoustic wave resonators and surface acoutstic wave resonators are widely used for front end filtering technologies, but their high quality factor, small size, and low power makes them good candidates for sensing technologies. [10, 11, 12] In this work, FBARs are applied to VOC sensing and infrared sensing sucessfully.
