Abstract:

Thesis (MSocialWork)--Stellenbosch University, 2001. ENGLISH ABSTRACT: This exploratory and applied study was undertaken to compile a generalized profile, understand the target group's needs and to formulate a set of directives for an intervention program for adolescent children of alcoholics. The Christian Action for Dependence (CAD) views alcoholism as a factor that affects every member of the household and adopts a systemic approach for solving this problem. An earlier study proofed that the organization does not provide sufficiently for the intervention of adolescent children whose parents are members of the self-help groups. In order to address this shortcoming, the Teencads (Teenage Christian Action for Dependence) was established in 1997. It functioned as a penfriend's club. The current study was prompted by the need for greater clarity in planning programs for a group like Teencads. A literature study was undertaken to assess the effect of parental alcoholism on adolescents. The research focused on the developmental tasks of adolescence; looked into the child's emotional reaction to parental alcoholism; highlighted the child's reaction in respect of different relationships and determined the effect of parental alcoholism on the academic performance of the child as well as the connection between parental alcoholism and pathological behavior of the child. Classical adaptive behavior by the children of alcoholics was studied by focusing on the contrast between observed behavior and the adolescent's underlying emotional reaction to parental alcoholism. The purpose of the literature study was to look for effective methods of intervention and intervention strategies, and to examine the aims and objectives of international programs that are currently being implemented. The empirical study focused on the CAD in the Western- and Southern-Cape. Twenty seven adolescents were selected by cluster sampling and the snowball technique. They completed a questionnaire that was compiled from the studied literature. The results of the empirical study strengthened the hypothesis that parental alcoholism has a negative effect on the development of adolescents and that social work intervention is a matter of urgency. Based on the results of the study, the researcher proposed policy guidelines for intervention programs for adolescents in the CAD. Guidelines and suggestions for such programs have been formulated. The recommendations of this study are applicable to adolescent children of all alcoholics. Organizations other than the CAD, as well as other social workers, will be able to use these recommendations in the formulation of intervention programs for adolescent children of alcoholics. AFRIKAANSE OPSOMMING: 'n Verkennende en beskrywende studie is onderneem om 'n veralgemeenbare profiel van die adolessente kinders van alkoholiste vas te stel, asook om te bepaal wat die behoeftes van hierdie teikengroep ten opsigte van 'n intervensieprogram is. Die uiteindelike doel van die ondersoek was om riglyne vir 'n intervensieprogram ten opsigte van adolessente kinders van alkoholiste te formuleer. Die Christelike Afhanklikheidsdiens (CAD) werk vanuit 'n sistemiese benadering en beskou alkoholisme as 'n probleem wat elke lid van die gesin beïnvloed. 'n Voorafondersoek het bewys dat die organisasie nie voldoende voorsiening maak vir intervensie van adolessente kinders wie se ouers lede van die selfhelpgroepe is nie. In 'n poging om hierdie leemte aan te spreek, is die Teencads (Tiener Christelike Afhanklikheidsdiens) in 1997 gestig en funksioneer dit onder leiding van die ondersoeker as 'n penvriendeklub vir hierdie teikengroep. 'n Behoefte aan meer rigting en duidelikheid ten opsigte van programinhoud, het hierdie ondersoek genoop. 'n Literatuurstudie is onderneem om die invloed van ouer-alkoholisme op adolessente te bepaal. Tydens die ondersoek is die ontwikkelingstake van die adolessente lewensfase in ag geneem; die kind se emosionele reaksie op oueralkoholisme ondersoek; die kind se reaksie in verskillende verhoudings waargeneem; die invloed van ouer-alkoholisme op akademiese prestasie en die verband tussen ouer-alkoholisme en patalogiese gedrag by adolessente vasgestel. Die klassieke aanpassingsrolle wat kinders van alkoholiste vertolk is ondersoek deurdat die navorser spesifiek op die kontras tussen waargenome gedrag en onderliggende emosies by die adolessent klem gelê het. In aansluiting by die doel van die navorsing is daar tydens die literatuurondersoek gefokus op die doelwitte vir 'n effektiewe intervensieprogram; metodes van intervensie; intervensiestrategieë, asook op die inhoud en intervensiemetodes van bestaande internasionale programme. Die empiriese ondersoek was op die CAD in die Wes- en Suid-Kaap gerig. Daar is 27 adolessente deur trossteekproeftrekking en 'n sneeubaltegniek geselekteer om 'n vraelys, gebasseer op die literatuurondersoek, te voltooi. Die resultate van die empiriese ondersoek bevestig die navorser se hipotese dat ouer-alkoholisme 'n negatiewe invloed op die ontwikkeling van adolessente het en dat maatskaplikewerk-intervensie noodsaaklik is. Op grond van die ondersoek en resultate, is 'n beleidsraamwerk ten opsigte van 'n intervensieprogram met kinders van alkoholiste, spesifiek vir die CAD geformuleer en volledige en omvattende riglyne en voorstelle vir sodanige program neergelê. Die aanbevelings van hierdie ondersoek is van toepassing op adolessente kinders van alle alkoholiste en kan dus met vrug deur ander organisasies en maatskaplike werkers gebruik word.

Abstract:

With the advent of the internet and advances in computing power, the collection of very large high-dimensional datasets has become feasible { understanding and modelling high-dimensional data has thus become a crucial activity, especially in the field of pattern recognition. Since non-parametric density estimators are data-driven and do not require or impose a pre-defined probability density function on data, they are very powerful tools for probabilistic data modelling and analysis. Conventional non-parametric density estimation methods, however, originated from the field of statistics and were not originally intended to perform density estimation in high-dimensional features spaces { as is often encountered in real-world pattern recognition tasks. Therefore we address the fundamental problem of non-parametric density estimation in high-dimensional feature spaces in this study. Recent advances in maximum-likelihood (ML) kernel density estimation have shown that kernel density estimators hold much promise for estimating nonparametric probability density functions in high-dimensional feature spaces. We therefore derive two new iterative kernel bandwidth estimators from the maximum-likelihood (ML) leave one-out objective function and also introduce a new non-iterative kernel bandwidth estimator (based on the theoretical bounds of the ML bandwidths) for the purpose of bandwidth initialisation. We name the iterative kernel bandwidth estimators the minimum leave-one-out entropy (MLE) and global MLE estimators, and name the non-iterative kernel bandwidth estimator the MLE rule-of-thumb estimator. We compare the performance of the MLE rule-of-thumb estimator and conventional kernel density estimators on artificial data with data properties that are varied in a controlled fashion and on a number of representative real-world pattern recognition tasks, to gain a better understanding of the behaviour of these estimators in high-dimensional spaces and to determine whether these estimators are suitable for initialising the bandwidths of iterative ML bandwidth estimators in high dimensions. We find that there are several regularities in the relative performance of conventional kernel density estimators across different tasks and dimensionalities and that the Silverman rule-of-thumb bandwidth estimator performs reliably across most tasks and dimensionalities of the pattern recognition datasets considered, even in high-dimensional feature spaces. Based on this empirical evidence and the intuitive theoretical motivation that the Silverman estimator optimises the asymptotic mean integrated squared error (assuming a Gaussian reference distribution), we select this estimator to initialise the bandwidths of the iterative ML kernel bandwidth estimators compared in our simulation studies. We then perform a comparative simulation study of the newly introduced iterative MLE estimators and other state-of-the-art iterative ML estimators on a number of artificial and real-world high-dimensional pattern recognition tasks. We illustrate with artificial data (guided by theoretical motivations) under what conditions certain estimators should be preferred and we empirically confirm on real-world data that no estimator performs optimally on all tasks and that the optimal estimator depends on the properties of the underlying density function being estimated. We also observe an interesting case of the bias-variance trade-off where ML estimators with fewer parameters than the MLE estimator perform exceptionally well on a wide variety of tasks; however, for the cases where these estimators do not perform well, the MLE estimator generally performs well. The newly introduced MLE kernel bandwidth estimators prove to be a useful contribution to the field of pattern recognition, since they perform optimally on a number of real-world pattern recognition tasks investigated and provide researchers and practitioners with two alternative estimators to employ for the task of kernel density estimation.

In this thesis, the stabilization and tracking problem of the Van der Pol oscillator is studied by using advanced control techniques. First, the linear state feedback and linear adaptive state feedback controllers for the stabilization problem are designed. Then, non-linear state feedback and output feedback controllers are proposed for the tracking problem with known parameters. Finally, a dynamic output feedback controller based on adaptive backstepping technique is introduced for the tracking problem when all parameters of the Van der Pol system are unknown. M.S.E.E.

Abstract:

Art History Ph.D. In Painting in Paris: Vincent Van Gogh, 1886-1888, Christa DiMarco explores the two-year period Van Gogh lived and worked in Paris. The paintings the artist made in The Netherlands, where he lived prior to Paris, and those he produced in Arles, where he moved afterward, usually receive scholarly attention. The imagery from the artist’s time in the capital is generally marginalized. DiMarco considers how and why the artist used a brighter palette and energetic brushwork while painting in Paris. Considering that his artistic practice spanned only a decade from 1880 to 1890, the artist’s time in the capital represents a significant period of growth in terms of his engagement with the art market, his exposure to avant-garde imagery, and his understanding of Symbolist theory in the visual arts. Van Gogh accomplished significant goals in Paris, though some of his well-developed imagery does not necessarily figure into discussions regarding the canonical paintings of the artist’s body of work. Attention to the Paris-period not only locates Van Gogh’s pictorial development within the context of the Impressionists and Neo-Impressionists, but also establishes the ways in which the artist diverged from the artistic aims of the Parisian avant-garde, such as Claude Monet and Camille Pissarro, as he developed his Symbolic approach.

Abstract:

Den här rapporten beskriver ett examensarbete för högskoleingenjörsexamen i datorteknik vid Växjö universitet. Vid företaget BSR i Växjö pågår utvecklingen av ett diagnosverktyg benämt BSR Diagnostic Tool. Syftet med projektet är att kunna använda en hårdvaruklass som kommunikationsdel istället för diagnosverktyg från de olika biltillverkarna. Inom objektorienterad programmering är en klass ett avsnitt programkod som samlar en mängd relaterade attributer och funktioner för ett objekt. I rapporten beskrivs implementeringen av hårdvaruklassen samt tillhörande teori för kommunikationsbussen som används, nämligen CAN. BSR har redovisat vilka funktioner som bör finnas med i klassen genom att göra ett diagram med dessa. Målet i första hand var att få en fungerande kommunikation med styrenheter i en Saab. Testning har skett genom ett enkelt testprogram som ger möjlighet att skicka en fråga och få tillbaka ett svar från en styrenhet i fordonet genom hårdvaruklassen. Utvecklingen av systemet har skett med hjälp av programspråket C# och utvecklingsmiljön .NET. Företagets representanter var nöjda med resultatet då det utgör en bra grund för vidareutvecklingen av BSR Diagnostic Tool. This abstract describes the bachelor degree thesis in computer technology at Växjö University. At the company BSR in Växjö, Sweden there is a new project under development called BSR Diagnostic Tool. The main idea is to use a hardware class for communication instead of the diagnostic tools that are provided by the car manufactures. In object-oriented programming, a class is a programming language construct that is used as a blueprint to create objects. The task was to implement this hardware class which will handle the communication between a computer and the control units in the vehicles. The report also includes a big theoretical part about the communication bus that is used, CAN. The objective was to create the class and make it communicate successfully with a Saab. The testing of the class was done with a simple program. The program can send a question to the vehicle and retrieve an answer with help of the hardware class. BSR provided a diagram with functions that should be present. The development of the system was done using C# and .NET Environment. The company was satisfied with the results since they provided a good basis to further development of BSR Diagnostic Tool.

Abstract:

Bakgrund: I och med att Basel II har instiftats i Sverige så måste finansiella institutioner beräkna sin marknadsrisk på sina portföljer. Detta kan göras genom olika VaR metoder. Dessa ger dock olika uppskattningar på marknadsrisken. De finansiella instituten får använda sig av den metod som de anser reflektera marknadsrisken bäst. Det finns dock ingen metod som utsetts till standard.Syfte: Syftet med detta arbete är att jämföra olika VaR-metoders skattning av marknadsrisken utifrån verkligt utfall, för att urskilja vilken metod som är funktionsdugligast.Avgränsningar: Denna undersökning inkluderar fyra olika VaR metoder. Dessa är Historisk Simulation, Delta-Normal, RiskMetrics och GARCH(1,1). VaR metoderna kommer att undersökas på portföljer som endast består av svenska aktier noterade på Stockholmsbörsens Large-, Mid- eller Small Cap lista.Metod: Vi har konstruerat fyra olika portföljer som vi sedermera har beräknat VaR för mellan 1998-04-01 t.o.m. 2008-04-01. Dessa uppskattningar har sedermera jämförts, m.h.a. backtesting, med det verkliga utfallet för portföljerna. Utifrån detta har vi analyserat vilken form av metod som är funktionsdugligast.Resultat, slutsatser: Vi kan konstatera att ingen av de metoder som vi har undersökt är godkända enligt vår backtesting. Om vi bortser från detta så verkar RiskMetrics vara funktionsdugligast då denna metod innehar få överträdelser och uppskattar marknadsrisken på ett effektivt sätt. Detta samtidigt som RiskMetrics är stabilast under hela undersökningsperioden.

Full text

Abstract:

Broar är bärverk som för trafik över eller förbi hinder och behöver ibland förstärkning av grundläggningen under stöden på grund av dåliga markförhållanden. Detta åstadkommas genom pålgrundläggning under bottenplattan. För att välja lämpliga pålar med tillräcklig lastkapacitet behövs beräkna dimensionerande lasteffekten från bron på pålarna i pålgruppen. Beräkningsprogram som grundas på pålstyvhetsmetoden för att beräkna lasteffekten på pålar används oftast, som CAE-rymdpålgrupp program. Sådana program betraktar bottenplattan som oändlig styv vilket troligen kan minska noggrannheten av beräkningen. Nyare program baserade på finita elementmetoder som FEM-Design kan beräkna lasteffekten på pålarna och har även möjlighet att välja olika styvheter till bottenplattan. För utvärdering och jämförelse mellan CAE och FEM-Design i syfte att välja lämpligaste program för beräkning av lasteffekten på pålarna vid pålgrundläggning av brostöd, valdes en bro i Telegrafberget, Nacka. Modellering och beräkning i båda program utfördes med hänsynstagande till tre parametrar; bottenplattans tjocklek, krypning och jordpåverkan. Efter analysen och jämförelsen mellan resultaten av båda program dras slutsatsen att FEM-Design ger noggrannare resultat för lasteffekten på pålarna. Vid hög styvhet för pålgrundläggningen ger CAE också adekvata resultat för lasteffekten. Bridges are structures that lead traffic over or through obstacles and sometimes require reinforcement of foundation under support due to poor soil conditions. This is accomplished by piling under the foundation slab. To select suitable piles with sufficient load capacity, it needs to calculate the dimensioning load effect from the bridge on the piles of the pile foundation. Calculation programs based on the pile stiffness method to calculate the loading effect on the piles are usually used such as the CAE program. Such programs regard the foundation slab as endless rigid which can probably reduce the accuracy of the calculation. Newer programs based on finite element methods like FEM-Design can calculate the load effect on the piles and also have the option of selecting various stiffnesses to the foundation slab. For the evaluation and comparison of CAE and FEM-Design in order to choose the most suitable program for calculating the load effect on the piles of bridge support, a bridge was chosen in Telegrafberget, Nacka. Modeling and calculation in both programs were performed taking into account three parameters; foundation slab thickness, creepage and ground effect. Following the analysis and comparison of the results of both programs, concludes that FEM-Design provides more accurate results for the loading effect on the piles. At high rigidity for the pile foundation, CAE also provides adequate results for the load effect.

Abstract:

Art History M.A. Northern European and Italian Renaissance art have tended to be treated art historically as two opposing styles. Rooted in statements by artists such as Michelangelo and Leon Battista Alberti, it has become a common misconception that Italians did not hold Northern European art in high regard during the late fifteenth and early sixteenth centuries. This thesis seeks to complicate and critique this conventional understanding by looking at the similarities and transalpine exchanges between the artistic styles and practices of Rogier van der Weyden (c. 1400-1464) of Brussels and Cosmè Tura (c. 1430-1495) of Ferrara. By looking at the writings of contemporary humanists at the Ferrarese court and technical analysis of select paintings, it is evident that Cosmè Tura strove to emulate and incorporate aspects of Rogier van der Weyden’s northern manner, especially in his handling of oil paint, use of underdrawings, and emotive effects. By reconsidering this cross-cultural relationship, this thesis demonstrates that the traditionally constructed animosity between Northern and Southern Renaissance art is a common misperception and a oversight in art history.

Abstract:

Art History M.A. Rogier van der Weyden's Miraflores Altarpiece (c. 1440) was installed in the Carthusian Monastery of Miraflores, Castile, during a period when early rosary meditation cycles were gaining popularity, particularly amongst Carthusians. This previously unexplored historical context offers a rationale for the innovative iconographic content and structure of the work, as well as for the ways in which it had meaning for its viewers. Like early rosary meditations, the Miraflores Altarpiece combines diverse meditational cycles including life of Christ and the Virgin narratives with the tripartite division of the Marian Psalter. The altarpiece has much in common with the later standardized form of the rosary, which indicates that this format had much earlier roots than had been thought previously. The Miraflores Altarpiece contributes to our understanding of the way visual media participated in the rosary tradition, and of the ways that tradition developed and changed over the fifteenth and sixteenth centuries.

Abstract:

El proyecto que presentamos en este trabajo, al cual decidimos llamar "Habla, Vas", consiste en un sistema de conexión mediante información relevante de demanda y oferta entre personas que necesiten movilizarse en un taxi colectivo a través de las principales rutas de la ciudad y colectiveros que necesiten generar mayores ingresos en estas rutas con mayor afluencia de tráfico en Lima. La idea de negocio parte de la necesidad de los autores por movilizarnos rápido, seguro y fácil por la ciudad, sin utilizar medios de transporte públicos que hacen que la experiencia de viajar sea incómoda, por la alta demanda del servicio y poca oferta. Esta situación, que se presenta a diario en miles de limeños, puede ser solucionado mediante una aplicación que simplifique el proceso de intercambio de información y nos evite caer en situaciones incómodas a las que los taxis colectivos tradicionales nos exponen. Asimismo, luego de la evaluación financiera preliminar del proyecto, notamos que el mismo tiene un potencial de rentabilidad altamente explotable, que constituye una oportunidad inmejorable para ser los primeros en este segmento, logrando lo que en su momento consiguió empresas como Uber o Globo. Además, se requiere una inversión relativamente pequeña frente a un negocio convencional y será totalmente accesible a través de las tiendas de Android y Apple. Finalmente, este proyecto será nuestra mejor carta de presentación e ingreso en el mundo de los negocios para nuestros futuros proyectos, ya que hemos recabado la información necesaria para entender la operación de ellos. The project that we present in this document, which we decided to call "Habla, Vas", consists of a connection system through relevant information of demand and supply, between people who need to move in a group through the main routes of the city and groups who need to generate income on these routes with the highest traffic flow in Lima. The business idea stems from the authors' need to move quickly, safely and easily around the city, without using public means of transport that make traveling uncomfortable, due to the high demand for the service and low supply. This situation, which occurs daily in thousands of Lima, can be solved through by the application that simplifies the process of information exchange and prevents us from falling into uncomfortable situations to which traditional groups expose us. Likewise, after the preliminary financial evaluation of the project, we note that it has a highly exploitable profitability potential, which constitutes an unbeatable opportunity to be the first in the segment, achieving what companies such as Uber or Globo achieved at the time. Also, a relatively small investment is required compared to a conventional business and will be fully accessible through Android and Apple stores. Finally, this project will be our best letter of introduction and entry into the business world for our future projects, since we have collected the necessary information to understand their operation.

Abstract:

Modern electric power utilities are facing a variety of challenges introduced by the increasing complexity of their operation, structure, and consumer loads. One such challenge has been to supply the ever growing demand for reactive power which is essential for grid support. For this reason dynamic VAR technologies are becoming much more important to modern day power systems. A recent dynamic VAR technology known as the Dynamic Capacitor offers full quadrant capacitive VAR control through the combination of AC/AC buck and boost cells. This paper introduces a new topology deemed the “Four-Switch Buck-Boost Dynamic Capacitor” which promises to combine the performance of the AC/AC buck and boost cells into a single power electronic device. This is done in an effort to reduce the required component count and thus reduce the overall device footprint and implementation cost of the Dynamic Capacitor technology. Derivations and analysis will detail the workings of the Four-Switch Buck-Boost Dynamic Capacitor, while simulations in LTSpice and Matlab Simulink will demonstrate the functionality and performance of the proposed topology. The results of this thesis prove the Four-Switch Buck-Boost Dynamic Capacitor to be a feasible shunt reactive compensating device.

Abstract:

Les marchés financiers occupent, depuis des décennies, une place importante dans notre société. Pourtant, ils présentent des risques accrus auxquels font face la majorité des institutions financières. Les crises, les krachs, les bulles et les turbulences financières jalonnent l’histoire de ces marchés et les déstabilisent fréquemment. En effet, l’existence des anomalies et des biais psychologiques, allant à l’encontre de l’hypothèse d’efficience, remettent en question la théorie financière et révèlent de façon rigoureuse les inefficacités des mécanismes de gestion financière et de contrôle du risque du marché. Confrontés à ces évolutions, le comité de Bâle II recommande la Value at Risk comme une nouvelle vision réglementaire des risques. Ce processus d’innovation financière, introduite par la banque JP Morgan dans les années 90, a connu une grande reconnaissance en finance, mais elle est aussi sujette à des controverses continuelles. Pour surmonter les limites de la VaR, nous proposons un nouveau cadre d’analyse de la VaR basé sur des processus fractals. Tenant compte des anomalies et des facteurs de risques du marché financier, qui induisent des rendements par nature non-gaussiens, nous introduisons la VaR en fonction du modèle multifractal à changements de régime markovien de Calvet et Fisher. L’approche VaR-MSM qui modélise la volatilité multifractale à différentes fréquences constitue un aperçu différent d’évaluation du risque du marché. En appliquant ce modèle sur l’indice boursier français le CAC 40, les résultats obtenus révèlent que la VaR-MSM a surpassé assez nettement les autres modèles d’évaluation de la VaR Financial markets occupy an important place in our society. However, they present increased risks to financial institutions. Crises, crashes, bubbles and financial turbulence often destabilize these markets. Indeed, the existence of different anomalies and psychological bias, going against the hypothesis of efficiency, put into question financial theory and present an inefficiency of financial and risk management. Faced with these effects, Bale II committee recommended Value at risk as a new financial instrument of risk management. Value at Risk, introduced by JP Morgan Bank in the 90, have a great recognition in finance, but it is also a subject of controversy. To overcome the VaR limits, we propose a new framework based on fractal process. Taking into account abnormalities and risk factors of financial markets, which induce non-Gaussian returns, we introduce the VaR with a Markov-switching multifractal model proposed by Calvet and Fisher. The VaR-MSM approach presents multifractal volatility at different frequencies. We apply this model to the France CAC 40 stock market index. The results clearly show the advantages of VaR-MSM compared with other models of VaR evaluation

Abstract:

Applied Behavioral Analysis M.S.Ed. Performance feedback has long been a popular strategy for organizational change (Fairbank & Prue, 1981). One of the primary advantages of performance feedback interventions is the relatively low cost of implementation for organizations when compared to other productivity-enhancement techniques, such as monetary incentives (Yukl, Wexley, & Seymore, 1972) like pay for performance (Lazear, 1995) or employee of the month programs with rewards associated with them (Daniels, 2000). Performance feedback is beneficial to ensure that employees are knowledgeable of the expectations, and what aspects of job performance need to be improved. Three studies (i.e., Betchel, McGee, Huitema, & Dickinson (2015); Alajadeff Abergel, Peterson, Wiskirchen, Hagen & Cole (2017) and Wine et. al. (2019)) have published research evaluating feedback presented prior to completion of a task; however, results varied. The current study evaluated whether feedback presented prior to a performance event improves performance when compared to a baseline condition where no feedback was presented.

Examination Committee: Chairperson: MGEN/ENGAER 076441-J Paulo Manuel Veloso Gonçalves Guerra (DMSA); Supervisor: MAJ/ENGAER 129905-A Luís Filipe da Silva Félix (AFA); Supervisor: CAP/ENGAER 131603-G João Vítor Aguiar Vieira Caetano (AFA); Member of the Committee: Doutor Frederico José Prata Rente Reis Afonso (IST) Esta tese destina-se ao design estrutural em materiais compósitos de um Veículo Aéreo Não-Tripulado (VANT) de classe I para vigilância marítima. A intenção de expandir o uso de VANTs pela Força Aérea Portuguesa (FAP), na ampla área de jurisdição portuguesa e nas operações internacionais, motivou a necessidade de desenvolver uma nova plataforma capaz de cumprir todos os requisitos operacionais e tecnológicos. A presente tese começa pela definição dos sistemas a bordo necessários para a aeronave, nomeadamente a carga útil, aviónicos e propulsão. O design estrutural ao nível conceptual e preliminar envolveu o planeamento da disposição geral da aeronave para atingir uma margem estática longitudinal válida e a determinação do envelope de voo com rajada para determinar o factor de carga da aeronave. Este parâmetro vai definir a caracterização das forças aerodinâmicas e inérciais para a manobra crítica de voo. O projecto detalhado da aeronave foi realizado através de modelação em Desenho Assistido por Computador (CAD) com o objetivo de minimizer o peso estrutural. O design foi confirmado por uma análise numérica de tensões através de uma Análise de Elementos Finitos (FEA) e foi alcançada convergência para os valores obtidos de tensão e de deslocamento. O design desenvolvido é capaz de suportar a condição de carga crítica sem falha estrutural. A configuração da aeronave com todos os sistemas a bordo apresenta um peso dentro dos limites para a respectiva classe e uma autonomia de oito horas para operações de vigilância marítima. O design desenvolvido pode apresentar outras configurações, e tem uma autonomia máxima de doze horas. This thesis concerns the composite structural design of a class I Unmanned Aerial Vehicle (UAV) for maritime surveillance. The intention to expand the UAV use by Portuguese Air Force (FAP), over the broad area of Portuguese jurisdiction and in international operations, motivated the need to develop a new platform capable to fulfil all the operational and technological requirements. This thesis starts by defining all the necessary onboard systems for the aircraft, namely the payload, avionics and propulsion. The conceptual and preliminary structural design involved planning the general layout to achieve a valid longitudinal static margin and determining the aircraft flight envelope with gust loads to determine the design load. This design driver set the aerodynamic and inertial load characterization of the critical flight manoeuvre. The aircraft detailed design was performed through Computed Aided Design (CAD) modelling with the objective of minimizing the structural weight. The design was endorsed by a numerical stress analysis through a Finite Element Analysis (FEA) and achieved convergence for the stress and displacement results. The developed design withstands the critical load condition without failure of the structure. The aircraft configuration with full payload presents a weight within its class range and an endurance of eight hours for maritime surveillance operations. The implemented design supports other configurations, presenting an endurance up to twelve hours. N/A

Full text

Abstract:

This study focuses on the rhetorical and political conditions for answering the question 'what is kulturpolitik?'. The most common translation of kulturpolitik is 'cultural policy', but 'cultural politics' is an alternative - perhaps policies must always involve broader notions of politics. Here, politics is understood as struggles and conflicts in community, struggles that take place between rules and practical cases, between law and freedom. It is argued that language is a key to an awareness of political conditions, although politics also might involve aesthetics and violence. According to Aristode and Ricoeur, language is something that occurs 'when somebody says something to somebody about something' - and, as added in the dissertation: 'for a certain purpose and in a certain manner'. The general conditions for saying what kulturpolitik is, can thus be studied with reference to the interplay between six aspects: author; utterance, audience, reference, purpose and manner These rhetorical aspects can be used differendy in different cases. Four particular cases are examined in the dissertation. These are chosen pardy because they allow a general overview of the connections between politics and the arts, or policy and culture, mainly in Western Europe; and pardy because they allow a demonstration of the importance of rhetoric. The cases are: (1) a comparison between two major Government Bills to the Swedish Parliament, concerning the general formulation of state cultural policy; (2) an analysis of the meaning of goals in policy, with particular reference to the Council of Europe's evaluations of cultural policies in France, Sweden, Austria, the Netherlands, and Finland; (3) an overview of the political uses of the concept of culture in Germany between 1800 and 1932; (4) a study of the French state's effort to engage the arts in the service of the republic between 1789 and 1983. It is, furthermore, argued that a rhetorical 'manner' can be understood as a way of employing the faculty of judgement. Following Aristode and Kant, and especially according to Arendt and Lyotard, it is shown that judgement is a pre- eminendy political faculty. It allows those who use language - authors as well as audiences — to reflect upon the conditions of agreement in the absence of preconceived rules, but with the help of aesthetical awareness and imagination.

Full text

Abstract:

The NASA SeaWinds scatterometer is a radar remote sensor which operates on two satellites; NASA's QuikSCAT launched in June 1999 and on Japan's ADEOS-II satellite launched in December 2002. The purpose of SeaWinds is to provide global measurements of the ocean surface wind vector. On QuikSCAT, a ground data processing algorithm was developed, which allowed the instrument to function as a QuikSCAT Radiometer (QRad) and measure the ocean microwave emissions (brightness temperature, Tb) simultaneously with the backscattered power. When SeaWinds on ADEOS was launched, this same algorithm was applied, but the results were anomalous. The initial SRad brightness temperatures exhibited significant, unexpected, ascending/descending orbit Tb biases. This thesis presents an empirical correction algorithm to correct the anomalous SeaWinds Radiometer (SRad) ocean brightness temperature measurements. I use the Advanced Microwave Scanning Radiometer (AMSR) as a brightness temperature standard to calibrate and then, with independent measurements, validate the corrected SRad Tb measurements. AMSR is a well-calibrated multi-frequency, dual-polarized microwave radiometer that also operates on ADEOS-II. These results demonstrate that, after tuning the Tb algorithm, good quality SRad brightness temperature measurements are obtained over the oceans. M.S.E.E.

Abstract:

Cette thèse a pour objet d'éclairer la matérialité de l'image dans le cinéma contemporain, à travers les œuvres de Stanley Kubrick, Alexandre Sokourov, Tsai Ming-liang et Gus Van Sant. Pour comprendre l'apport de l'esthétique de la matière, cette étude relève les éléments de fluidité dans leurs films, mais aussi cherche à montrer comment ces cinéastes font apparaître la qualité sensible de la matière par le langage cinématographique, c'est-à-dire par l'image. La première partie étudie le rapport entre la matière et la forme dans les œuvres de Stanley Kubrick et d'Alexandre Sokourov. Dans « Shining » (1980) de Kubrick, la matière visqueuse déchire et déborde de la maison-forme, tandis que chez Sokourov, le musée-forme qui apparaît dans « Hubert Robert. Une vie heureuse » (1996), « Elégie de la traversée » (2001) et « L'Arche russe » (2002) se construit en tant qu'espace-milieu où le mouvement de la caméra dégage la perception liquide. La deuxième partie explore ce que manifestent les éléments liquides dans les œuvres de Tsai Ming-liang. L'écoulement liquide détermine pour cet auteur l'état du monde : le corps, la maison, le cinéma sont tous trois inclus dans ce régime de l'écoulement. La troisième partie étudie les variations de la consistance de l'eau dans les œuvres de Gus Van Sant. L'image de cet élément liquide devient fluide. Le cinéma rencontre le monde sensible à travers l'expressivité de la matière. En fluidifiant, le cinéma nous force à penser le monde qui se donne au changement.

Full text

Abstract:

Civil rights have long been an important focus of historical scholarship. As the United States continues to grapple with issues of racism and the complicated legacy of the Civil Rights Movement, it is imperative that a variety of perspectives are incorporated into scholarship on the subject. Traditional scholarship on the subject has focused on the large organizations, individuals, marches, and activities that have come to characterize the Civil Rights movement. This study seeks to integrate the perspectives of a case study population, African Americans in San Luis Obispo, California, to assess the ways in which African Americans away from large population centers were able to participate in the Civil Rights movement. This study draws primarily on contemporary newspapers, NAACP records, and government documents to assess the relationship between the local civil rights movement and its national counterpart. Civil rights activities at California Polytechnic State University, San Luis Obispo also reveal important instances of discrimination and exclusion on campus. Research has shown that, despite relative isolation and a miniscule population, African Americans in San Luis Obispo experienced similar discrimination, isolation, and economic exclusion as their urban and rural counterparts throughout the nation. They also attempted to bring attention to their plight using nationally established organizations and tactics. Though African Americans in San Luis Obispo met with limited success, their previously undocumented struggle has revealed a population determined to fight for their rights. The continuity between the experiences of African Americans throughout the country renders a more complete understanding of racism in the United States.

Abstract:

ABSTRACT A Floristic Study of the Cal Poly Swanton Pacific Ranch and a New Combination in Sanicula crassicaulis (Apiaceae), Sanicula crassicaulis var. nudicaulis Reed J. Kenny Globally we are experiencing a biodiversity crisis and potentially a sixth mass extinction event. Plant specimens are one of the best, most concrete records of biodiversity that we can create. Despite this, the rate of plant collecting has declined steeply since World War II. Now more than ever, plant collections are vital, both for the purpose of quantifying the plant biodiversity in an area and for discovering previously unrecognized diversity. In Chapter 1, we conducted a floristic survey of the Cal Poly Swanton Pacific Ranch. The Swanton Pacific Ranch (SPR) is located north of the small town of Davenport California, in Santa Cruz county. SPR is 3,200 acres and contains areas of salt marsh, coastal bluff, coastal prairie, riparian forest, redwood forest, mixed conifer forest and chaparral in approximate ascending order of elevation. The property extends over an elevational gradient from 0 m to 420 m (1400 ft). We documented 634 taxa at SPR. In total, 974 specimens were collected during this project, 405 specimens in 2017 and 569 in 2019. We reviewed 211 historic specimens. We vouchered 546 taxa between 2017 and 2019 and observed but did not collect 6 taxa. 53 taxa are represented from historic collections and were not relocated. There are 30 taxa listed as historically present from personal observations of the authors but without vouchers. Though these do not have the same value as a physical specimen, we believe that all information is valuable and have included them with a clear indication of the source of the record. There were 465 native and 169 non-native taxa documented in the study area. There were 93 families represented, with Asteraceae, Poaceae and Fabaceae be ing the top three most speciose respectively. There were 83 taxa noted as locally rare following Neubauer, of these 16 taxa have a California Native Plant Society (CNPS) rare plant rank. We vouchered one new taxon for Santa Cruz County, Senecio aphanactis, which has a CNPS rare plant rank of 2B.2 In Chapter 2, we describe a new combination in the Sanicula crassicaulis species complex. During the project detailed in Chapter 1, we observed and collected several specimens that keyed to Sanicula crassicaulis Poepp. ex. D.C. but were notably distinct from other S. crassicaulis that we collected in the area. On further investigation, we found that these plants match the type specimen of S. nudicaulis Hook & Arn., described in 1839 and later synonymized with S. crassicaulis. This taxon is distinguished primarily by its long, sinuate marginal leaf trichomes, in contrast to the short, straight marginal trichomes of S. crassicaulis. Additionally, the length of the most proximal prickles on the schizocarps is about the same as the length of the most distal rather than the distal prickles being much longer as in S. crassicaulis and the angle of attachment of the prickles is more or less perpendicular as opposed to acute in S. crassicaulis. The known range of this taxon is between the San Francisco Bay Area and Santa Barbara County, generally near the coast. Here we recognize this taxon as a variety in S. crassicaulis, Sanicula crassicaulis var. nudicaulis. We provide a diagnosis, a map of the known range of the taxon and a key to the varieties of S. crassicaulis. Overall this project has significantly increased or knowledge and documentation of the flora of both SPR and Santa Cruz county. In addition to the immediate benefits of this study (a complete species list for SPR, the discovery of a new taxon, and the mapping of all rare species at SPR) we have also contributed almost 1,000 physical specimens to the Cal Poly Hoover herbarium which may be used in future taxonomic and ecological studies.

Full text

Abstract:

This thesis explores the development of a series of posters created by Howard Chandler Christy during the World War I era. During this time, Christy was a Department of Pictorial Publicity (DPP) committee artist commissioned by the committee chair, Charles Dana Gibson. The DPP was part of the Committee on Public Information (CPI) developed by the Woodrow Wilson administration to generate the propaganda necessary to gain the support of the American people to enter World War I. The CPI was headed up by George Creel, a journalist and politician, who used advertising techniques to create the first full-scale propaganda effort in United States history. American poster images of women during World War I represent an era when propaganda posters came of age. These iconographic interpretations depicted in political propaganda helped shape the history of the twentieth century. While exploring these portrayals of women, the observer looks through a historical lens to contemplate the role of propaganda in the American war effort, while considering the disparity between images of women and the reality of their experiences in the patriarchal society in which they lived. Howard Chandler Christy's war-related posters represented the gendered rhetoric of a social order that functioned under the well-established assumption that men and women both had their place in society based on gender-specific stereotypic characteristics. Women were central to propaganda posters from this era; their images were widely used in posters encouraging Americans to support the war effort. With few exceptions, these representations perpetuated traditional concepts of appropriate gender roles. Posters often used women as icons characterizing the nation in time of war. For example, a beautiful woman, with a backdrop of the United States flag or sometimes even dressed in Old Glory, suggested why the nation was fighting. Some posters explicitly used beautiful women to signify that America's honor was at stake and we needed fighting men to protect it. The poster art form spread rapidly during the early twentieth century, putting a woman in her place rather than challenging the historical circumstances that created the complex, problematic issues related to the visual representation. Reading these posters as cultural texts, it is apparent that women's images are central to gaining an understanding of the social norms and cultural expectations.

Abstract:

The focus of this research was to examine the initial year of implementation of the Marzano Teacher Evaluation Model and iObservation tool (Learning Sciences International, 2012) as it related to student achievement in the School District of Osceola County, Florida and to determine if the Marzano model improved the ability to determine teacher effectiveness with more accuracy than previous models of teacher evaluation used in the school district. Twelve research questions guided this study concerning the relationship and predictability between the variables of teacher instructional practice scores, number of observations reported in the iObservation tool, and student achievement in Grades 3-5 using reading and mathematics FCAT 2.0 DSS scores. Linear Regression analysis suggested that for Grade 3 reading and mathematics the instructional practice mean had statistical significance in predicting performance and was a strong predictor of Grade 3 FCAT reading and mathematics performance.

Linear Regression analysis further suggested no statistical significance or predictability for Grades 4, 5 for instructional practice mean and Grades 3,4,5 for observation mean related to FCAT reading and mathematics performance.

Abstract:

Bioengineering M.S. The tetra-peptide sequence alanine-valine-proline-isoleucine (AVPI) is derived from a known inhibitor of apoptosis inhibitor proteins (IAPs) called Smac (second mitochondria-derived activator of caspases). Ala-Val-Pro-Ile can be further utilized as an anti-cancer agent by inhibiting the activities of apoptosis inhibitors so caspases can trigger apoptosis of cancer cells. AVPI, however, has poorly cell-penetration property thus limiting its ability to be utilized as a therapeutic agent for cancer treatments. We conjugated the AVPI molecule to a newly developed cell-penetrating peptide (CPP) called PepB to circumvent the situation of limited cellular availability. Solid Phase Peptide Synthesis (SPPS) methods have been utilized to prepared AVPI peptide derivatives. Key characterizations involve reverse-phase high-performance liquid chromatography (RP-HPLC), mass spectrometry, optical and fluorescence microscopy. Temple University--Theses

Abstract:

Inom kontexten medelstora svenska icke-finansiella företag är syftet med denna uppsats att undersöka hur sambandet mellan företagens skuldsättningsgrad och företagens sannolikheter för konkurs ser ut genom att tillämpa Byströms Distance to Default (DD). Uppsatsen ämnar besvara följande frågeställningar: (1) Hur ser företagens skuldsättningsgrad och sannolikhet för konkurs ut kvantifierade med Byströms DD? (2) Kan företagen öka andelen främmande kapital utan att nämnvärt öka sannolikheten för konkurs kvantifierat med Byströms DD? En empirisk metod utvecklas för att beräkna företagens skuldsättningsgrad, företagens sannolikhet för konkurs och för att öka andelen främmande kapital utan att nämnvärt öka sannolikheten för konkurs. Indelning av företagen sker på sektornivå. Om uppsatsens frågeställningar kan följande slutsatser dras: (1) företagens skuldsättningsgrad är olika beroende på sektortillhörighet och förändringar i marknadsvärdet av företagens tillgångar och förändringar i volatiliteten av marknadsvärdet av företagens tillgångar har en tydlig påverkan på företagens sannolikhet för konkurs (2) två av sektorerna (i.e. Informationsteknik och Sjukvård) kan öka andelen främmande kapital utan att nämnvärt förändra sannolikheten för konkurs. Tre av sektorerna (i.e. Industrivaror och tjänster, Material och Sällanköpsvaror och tjänster) uppvisar högre skuldsättningsgrader och en tänkbar förklaring är att företagen kortsiktigt avviker från företagens långsiktiga skuldsättningsgrad. När företagens skuldsättningsgrad och sannolikhet för konkurs kvantifieras med Byströms DD uppvisar företag med hög skuldsättningsgrad en högre sannolikhet för konkurs – i enlighet med Trade-Off Theory.

Abstract:

Ventilator-associated pneumonia (VAP) is the leading healthcare-acquired infection among ventilated patients in intensive care units (ICU). VAP is a serious patient complication that results in increased hospital length of stay, cost, morbidity, and mortality. The accumulation of subglottic secretions above the endotracheal tube (ETT) cuff increases the risk of VAP, as these secretions may leak around the cuff of the ETT resulting in aspiration and an increased risk for infection. An in depth literature review was done to determine the effectiveness of subglottic secretion aspiration (by means of specialized ETT tubes with intrinsic suction lumens) in decreasing the incidence rate of VAP. Evidenced-based data were gathered from the CINAHL Plus with Full Text, PubMed, and Cochrane Database of Systematic Reviews databases for this review. VAP guidelines recommend subglottic secretion aspiration as a means to prevent its occurrence. However, important variables such as suction pressure, frequency, secretion viscosity, and ETT cuff pressure and volume need to be considered. The interaction among these variables determines the effectiveness of subglottic secretion removal. The goal of this review was to highlight these interactions and provide evidenced-based information for critical care nurses to expand their understanding of the dynamics involved in subglottic secretion aspiration and how to efficiently use this practice to prevent VAP.

Abstract:

Introduzione. L'Olea europaea è uno degli alberi più antichi della regione mediterranea. Gli estratti di foglie di olivo (Olive Leaf Extracts, OLE) hanno suscitato interesse nei ricercatori di diverse discipline scientifiche principalmente a causa della particolare composizione fenolica, presumibilmente correlata alla sua potente attività biologica. Obiettivi. Lo scopo di questo studio è stato valutare: a) le proprietà degli OLE di Olea europaea Toscana per proteggere le cellule endoteliali dallo stress ossidativo generato dalle specie reattive dell'ossigeno (ROS), sia in coltura 2D sia in innovativi scaffold 3D (P (VDF-TrFE)); b) studiare l'effetto antimicrobico di OLE rispetto alla tecnologia Cold Atmospheric Plasma (CAP), o la loro combinazione, contro agenti patogeni, ad esempio Escherichia coli, Staphylococcus aureus e Listeria innocua, cresciuti a livello esponenziale o in fase stazionaria; c) caratterizzare fibre composite elettrofilate a base di PHBHV caricate con OLE per applicazioni nella guarigione delle ferite; d) valutare la capacità di OLE incorporato nelle fibre di poliidrossialcanoati (PHA) di modulare il rilascio di citochine da cheratinociti umani sani (HaCaT). Metodi: I polifenoli totali (total polyphenols, TP) di OLE sono stati caratterizzati con il metodo di Folin-Ciocalteu. Le cellule endoteliali sono state coltivate in colture convenzionali (cioè bidimensionali, 2D) e su impalcature tridimensionali fabbricate tramite elettrofilatura. La vitalità cellulare e la misurazione dei ROS dopo lo stress indotto da H2O2 sono state eseguite tramite WST-1, alamar Blue e la sonda CM-H2DCFDA per ROS. La crescita di E. coli, S. aureus e L. innocua è stata valutata mediante il test di unità (CFU) formanti colonie (espressa in CFU/ml) e CAP. È stata eseguita la reazione a catena della polimerasi in tempo reale (real-time PCR) per valutare le proprietà immunomodulatorie; analisi di spettroscopia infrarossa in trasformata di Fourier (FT-IR), per discriminare la composizione chimica in entrambe le fibre elettrofilate; cromatografia a permeazione su gel (GPC) per consentire l'analisi della biodegradazione; microscopia SEM per lo studio della morfologia delle fibre ed in fine, HPLC per eseguire lo studio di rilascio. Risultati: il contenuto in TP di OLE era 23,29 mg di acido gallico equivalente (GAE)/g e l'oleuropeina era il composto principale. La curva di vitalità dose-dipendente ha evidenziato l'assenza di effetti citotossici significativi a concentrazioni di OLE inferiori a 250 μg GAE/ml di TP. Il pretrattamento di 100 μg GAE/ml di TP di OLE ha avuto effetti protettivi sullo stress ossidativo indotto da H2O2 in entrambi i modelli (2D e 3D). La combinazione di CAP e OLE ha determinato una sostanziale inattivazione microbica contro tutti i ceppi in fase esponenziale mostrando una completa inattivazione. OLE ha dimostrato una significativa attività antinfiammatoria, sottoregolando l'espressione di tutte le citochine proinfiammatorie e sovraregolando IL-8, IL-1α e TNF-α nel modello HaCaT. Conclusione: OLE possiede una significativa attività antiossidante e antinfiammatoria; la fibra a base di PHBHV + OLE preserva gli effetti benefici di OLE e rappresenta uno scaffold 3D di alto valore con un grande potenziale nella rigenerazione dei tessuti. CAP e OLE possiedono un'attività antibatterica sinergica; pertanto, la tecnologia CAP in combinazione con OLE può essere utilizzata per una decontaminazione efficace, ad esempio nella guarigione delle ferite ed in dispositivi biomedicali. Background. Olea europaea is one of the most ancient trees of the Mediterranean region. Olive leaf extracts (OLE) have aroused interest in researchers from different scientific disciplines mainly due to the distinctive phenolic composition allegedly related to potent biological activities. Objectives. The aim of the present s study was to evaluate: A) the properties of OLE extracted from the Tuscan Olea europaea to protect endothelial cells against oxidative stress generated by reactive oxygen species (ROS) in 2D culture and innovative 3D scaffold (P(VDF-TrFE)); B) to investigate the antimicrobial effect of OLE versus Cold Atmospheric Plasma (CAP) technology or their combination against pathogens, i.e., Escherichia coli, Staphylococcus aureus and Listeria innocua, grown to exponential (24h) or stationary (6h) phase; C) to characterize electrospun OLE-loaded PHBHV based composite fibers for wound healing applications; D) to evaluate the ability of OLE incorporated in Polyhydroxyalkanoates (PHAs) fibers to modulate the release of cytokines from healthy Human Keratinocytes (HaCaT). Methods: OLE total polyphenols (TPs) were characterized by the Folin–Ciocalteu method. Endothelial cells were grown in conventional cultures (two-dimensional, 2D) and on three-dimensional scaffold fabricated via electrospinning. Cell viability and ROS production after H2O2 insults were evaluated by WST-1, AlamarBlue and Probe CM-H2DCFDA assays. The E.coli, S.aureus and L.innocua growth were assessed by CFU/mL and CAP methods; Real-time polymer chain reaction (PCR) was carried out to evaluate the immunomodulatory properties; Fourier Transform Infrared Spectroscopy (FT-IR) Analysis was performed to discriminate the chemical composition in both electrospun fibers. Moreover, Gel Permeation Chromatography (GPC) to allow biodegradation analysis, SEM microscopy to study fiber morphology and HPLC to carry out the release study, were performed. Results: OLE TP content was 23.29 mg of gallic acid equivalent (GAE)/g, and oleuropein was the principal compound. The dose-dependent viability curve highlighted the absence of significant cytotoxic effects at OLE concentrations below 250 μg GAE/ml TPs. OLE preconditioning at 100 μg GAE/ml was protective against ROS in both models. The combination of CAP and OLE resulted in substantial microbial inactivation against all strains at exponential phase showing a complete inactivation. OLE possess a significant anti-inflammatory activity, downregulating the expression of all proinflammatory cytokines, upregulating IL-8, IL- 1α and TNF-α in HaCaT model. Conclusion. OLE possess a significant antioxidant and anti-inflammatory activities; PHBHV+OLE retains OLE beneficial effects and represents a high-value 3D scaffold with great potential in tissue regeneration. CAP and OLE have synergistic antibacterial activity; therefore, CAP technology in combination with OLE can be utilized for effective decontamination when required for example in wound healing and biomedical devices.

Abstract:

1868, Bruxelles, trente-quatre artistes, principalement des peintres belges, s’organisent en groupe sous la dénomination de « Société libre des Beaux-Arts ». Parmi eux, de nombreux peintres tenants du réalisme tels que Louis Artan, Alfred Verwée, Louis Dubois, Félicien Rops et Marie Collart. Désireux d’enrôler de nouveaux membres, ils publient leurs statuts et leur programme dont les axes principaux sont l’opposition au dogmatisme des peintres « conservateurs » et l’appui d’un « renouvellement des arts » à l’aune de la « liberté », du « progrès » et d’un respect de « (…) l’école nationale ». Durant son existence, la société organisera trois expositions en marge de l’institution et se munira d’une revue L’Art libre. En se focalisant sur la Société libre des Beaux-Arts (1868-1876) et ses artistes, notre thèse a pour objectif de contribuer à l’étude du fonctionnement et de la restructuration du monde artistique en Belgique dans la seconde moitié du XIXe siècle. La création d’une société d’artistes véhiculant des valeurs tant identitaires qu’esthétiques constitue en effet une nouvelle façon de s’imposer comme artiste dans la sphère publique. Auparavant, seules les infrastructures étatiques (Salons, Musées, Classe des Beaux-Arts, etc.) posaient les critères de mise en valeur d’une élite artistique. Par le biais d’une étude des stratégies médiatiques et commerciales de la société et des trajectoires professionnelles de quarante-trois peintres membres, nous proposons de confronter la posture collective d’artistes « indépendants » véhiculée à la réalité de leurs pratiques. Quels étaient les enjeux d’une telle structure adoptant une posture d’avant-garde à l’image de celle qui s’était forgée quelques années plus tôt à Paris ? Derrière cette construction identitaire, peut-on véritablement considérer ces artistes comme des « révolutionnaires » et des « indépendants » ? Qui étaient ces artistes ? Où exposaient-ils et quel type d’œuvre montraient-ils ? Ont-ils pu compter sur les moyens d’automédiation mis en place par le groupe pour assurer leur reconnaissance, trouver un public et vivre de leur art ? Quel fut leur rapport effectif aux institutions officielles ?Il s’agit d’observer les actions concrètes posées par ces acteurs afin d’assurer leur émergence et leur reconnaissance dans un champ artistique en mutation. Pour ce faire, nous avons ciblé trois « moyens de médiation » soit trois moments de mise en relation de leur personne et de leurs œuvres avec le public que sont l’exposition, la critique d’art et le marché de l’art. My research is focused on the careers of the painters who were members of the « Société libre des Beaux-Arts » (1868-1876), Belgium's first independent association of artists based on an aesthetic principle. With the aim of increasing the recognition and visibility of naturalistic paintings on the art scene, the association organized several exhibitions and published periodicals by supporting art critics. The « Société libre des Beaux-Arts » included approximately forty painters such as L. Artan, L. Dubois, C. Meunier and F. Rops. By analysing their use of exhibitions and the media, their critical reception and their place in the art market, I try to explore the emergence of the « independent artist » and the eventual transition from « the academic system » to « the dealer-critic system » in Belgium.

Abstract:

La mesure des courants marins de surface par radar HF soulève plusieurs problématiques au niveau de la calibration des radars, de la résolution spatiale et des signaux parasites. Le traitement conventionnel fonctionnant par balayage azimutal appelé formation de voie a une résolution angulaire limitée pour la plupart des radars à réseau de phase et les méthodes de traitement à haute résolution pour la recherche des directions d'arrivées produisent généralement des cartes lacunaires. Dans cette thèse nous proposons : a) une technique de traitement à haute résolution angulaire permettant d'obtenir des cartes pleines et peu bruitées ; b) une méthode de calibration automatique des antennes ; c) des méthodes de suppression des artefacts liés aux interférences radio et aux échos parasites. Ces méthodes, initialement prévues pour les radars à réseau de phase, ont été adaptées aux radars compacts CODAR dont la principale difficulté est la calibration en raison de la nature des antennes. Les mesures de courant obtenues avec ces nouvelles techniques ont été validées par des campagnes in situ avec des erreurs dans la fourchette basse de la littérature scientifique The measurement of sea surface currents by HF radar raises several issues in terms of radar calibration, spatial resolution and parasite signals. Conventional azimuth scanning processing called beam forming has limited angular resolution for most phased array radar and high angular resolution processing methods called direction finding generally produce lacunary maps. In this thesis we propose : a) a high angular resolution processing technique based on direction finding algorithm allowing to obtain full and low-noise maps ; b) an automatic antenna calibration method ; c) other methods to removing artifacts related to radio frequency interference and clutter echoes. These methods, initially planned for phased array radars, have been adapted to compact radars called CODAR where the main difficulty is the calibration due to the nature of the antennas. The measurements obtained with these new techniques have been validated with in situ campaigns with errors in the low range of the scientific literature

Abstract:

Höghastighetsmanipulation av nacken är en manuell behandlingsteknik mot smärta i framförallt nacken och skuldrorna. Tekniken har enligt flera källor visats hänga samman med risken för att drabbas av skador på de kärl som försörjer hjärnan med blod, med bland annat stroke som följd. Andra källor har å andra sidan visat att de är en teknik som är säker att utföra. Den här litteraturstudien har sammanställt och utvärderat forskning som på olika sätt söker utreda om det påstådda sambandet är kausalt eller inte. Metoden som valdes var att genom en av SBU färdigställd mall värdera forskningsartiklar och sedan sortera dem efter relevans, för att på så sätt avgöra huruvida sambandet kan ses som kausalt eller inte. Studieresultatet visade att frågan är för komplex för att kunna besvaras i en enskild studie, och att mer forskning behövs inom flera delområden innan frågan kan besvaras fullt ut. Orsaken till detta är att det finns flera orsaksmekanismer, och flera riskgrupper, för denna typ av skada, där flera ännu är okända. Detta gör att en fullständig kartläggning av samband i frågan ännu inte är möjlig. Däremot är det sannolikt att tekniken kan verka som en utlösande faktor, en trigger, hos vissa personer i riskgrupperna. Därför kan det sägas finnas en risk med tekniken rent praktiskt, oavsett om ett kausalt samband mellan tekniken och stroke i sig existerar eller inte. High Velocity Manipulation of the cervical spine is a manual treatment technique against pain in foremost the neck, shoulders. The technique has according to multiple sources been connected to the risk of injury to the blood vessels that supply the brain with blood, with among others stroke as a consequence. Other sources have on the other hand shown it the technique to be safe to perform. This literature study has compiled and evaluated research that in various ways tries to find out if said connection is causal The method used was to evaluate articles through a pre-made form from SBU, and then to sort them according to relevance to see if the connection is causal or not. The result showed that the question is too complex to be answered in a single study, and that more research is needed to answer the question in full. This is due to the fact that there are multiple mechanisms behinds this form om injury, that the risk seems to exists in certain groups, and that some of these are not yet identifiable. On the other hand there is a high probability that the technique might act as an activating factor in these groups. Because of this there can be said that a risk exists with the technique in practice, no matter if there is a casual connection between the technique and stroke in itself or not.

Abstract:

Does the individual really matter in the post-modern world, brimming with countless signs and signifiers? My main objective in this writing is to demonstrate how this happens in Verhoeven's films, exploring his central themes and subtext and doing what science fiction does: hold a mirror up to the contemporary world and critique it, asking whether our species' current trajectory is beneficial or hazardous.; Dutch director Paul Verhoeven is a polarizing figure. Although many of his American made films have received considerable praise and financial success, he has been lambasted on countless occasions for his gratuitous use of sex, violence, and contentious symbolism--1995s Showgirls was overwhelmingly dubbed the worst film of all time and 1997s Starship Troopers earned him a reputation as a fascist. Regardless of the controversy surrounding him, his science fiction films are a move beyond the conventions of the big blockbuster science fiction films of the 1980s (E.T. and the Star Wars trilogy are prime examples), revealing a deeper exploration of both sociopolitical issues and the human condition. Much like the novels of Philip K. Dick (and Verhoeven's 1990 film Total Recall--an adaptation of a Dick short story), Verhoeven's science fiction work explores worlds where paranoia is a constant and determining whether an individual maintains any liberty is regularly questionable. In this thesis I am basically exploring issues regarding power. Although I barely bring up the term power in it, I feel it is central. Power is an ambiguous term; are we discussing physical power, state power, objective power, subjective power, or any of the other possible manifestations of the word? The original Anglo-French version of power means "to be able," asking whether it is possible for one to do something. In relation to Verhoeven's science fiction work each demonstrates the limitations placed upon an individual's autonomy, asking are the protagonists capable of independent agency or rather just environmental constructs reflecting the myriad influences surrounding them.

Full text

Abstract:

L'approche traditionnelle des produits dérivés consiste, sous certaines hypothèses bien définies, à construire des stratégies de couverture à risque strictement nul. Cependant,dans le cas général ces stratégies de couverture "parfaites" n'existent pas,et la théorie doit plutôt s'appuyer sur une idée de minimisation du risque. Dans ce cas, la couverture optimale dépend de la quantité du risque à minimiser. Dans lecadre des options, on considère dans ce travail une nouvelle mesure du risque vial'approche de l'utilité espérée qui tient compte, à la fois, du moment d'ordre quatre,qui est plus sensible aux grandes fluctuations que la variance, et de l'aversion aurisque de l'émetteur d'une option vis-à-vis au risque. Comparée à la couverture endelta, à l'optimisation de la variance et l'optimisation du moment d'ordre quatre,la stratégie de couverture, via l'approche de l'utilité espérée, permet de diminuer lasensibilité de la couverture par rapport au cours du sous-jacent. Ceci est de natureà réduire les coûts des transactions associées The traditional approach of derivatives involves, under certain clearly defined hypothesis, to construct hedging strategies for strictly zero risk. However, in the general case these perfect hedging strategies do not exist, and the theory must be rather based on the idea of risk minimization. In this case, the optimal hedging strategy depends on the amount of risk to be minimized. Under the options approach, we consider here a new measure of risk via the expected utility approach that takes into account both, the moment of order four, which is more sensitive to fluctuations than large variance, and risk aversion of the investor of an option towards risk. Compared to delta hedging, optimization of the variance and maximizing the moment of order four, the hedging strategy, via the expected utilitiy approach, reduces the sensitivy of the hedging approach reported in the underlying asset price. This is likely to reduce the associated transaction costs
