No. of bitstreams: 1 arquivototal.pdf: 537788 bytes, checksum: f4d2088488947fc0f778709eac62f92b (MD5) Previous issue date: 2015-07-31 / Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPq / Supersymmetry is a very useful tool for extending the Standard Model up to the grand unification scale, studying electoweak symmetry breaking and providing dark matter candidates. The presence of superpartners solves the problem of divergences, and changes the renormalization group equations in a way that allows gauge coupling unification. In a global supersymmetry the breaking scale is proportional to the vacuum energy, which makes it incompatible with the low value of the cosmological constant. Promoting SUSY to a local symmetry results in supergravity, which mandates existence of a spin-2 gravitational field, naturally integrates General Relativity and particle physics, and is required to adjust the potential and obtain a high breaking scale with low cosmological constant. This review work looks into models based on gravity-mediated supersymmetry breaking. These models allow a simpler hidden sector than their gauge-mediated or anomay-mediated counterparts. And the lightest supersymmetric particles, higgsino-like, could be detected once an electron-positron collider such as ILC is ready. / A supersimetria ´e uma ferramenta muito ´util para estender o Modelo Padr˜ao at´e a escala de grande unifica¸c˜ao, para estudar a quebra de simetria eletrofraca e prover candidatos a mat´eria escura.

Cette thèse présente une étude du système à deux corps contrôlé en poussée faible, et en particulier, des problèmes de transferts orbitaux. Après une étude de contrôlabilité, nous nous focalisons sur le lien entre la commande optimale en temps minimum et les contrôles en boucle fermée construits à partir de la méthode de Jurdjevic-Quinn. Des simulations numériques montrent que les commandes Jurdjevic-Quinn peuvent être proches de la commande temps minimum. Pour comprendre cette propriété nous étudions un système contrôlé moyen dont les trajectoires approchent celles des systèmes à faible poussée. Cette technique nous permet de répondre à une conjecture concernant le comportement asymptotique du temps minimum quand la poussée tends vers zéro. D'autre part elle constitue une piste prometteuse pour construire une fonction de Lyapunov associée la méthode de Jurdjevic-Quinn efficace: un contrôle en boucle fermée proche de la commande optimale.

This thesis examines the pre-design documentation from the renovation of three historic theaters located in Detroit, Michigan. Two theaters hired architectural firms to produce a pre-design document. The third theater utilized a design-build approach to renovation. Interviews were conducted to review the approach and final outcomes. It became evident through the analysis of the documentation and interviews that it was beneficial in the renovation of a historic theater to have a comprehensive predesign process that identifies: the nature of the pre-design document, the nature of the client, the nature of the pre-design team, and the scope of work and time available. It also became apparent that the organizational approach that would apply to most any document for a heritage building should follow the Problem Seeking format of: Form, Function, Time and Economy. Utilizing this format for a pre-design record should yield a document that is concise, comprehensive and flexible.

Sammanfattning: Det mest märkbara resultatet i studien är att det inte krävs en stor aktör med många följare för att påbörja en stor kampanj, men det är nödvändigt att få hjälp av dem för att nå en viral spridning. De två studerade kampanjerna hade helt olika sätt att kommunicera på, där MeToo hade en allvarsam ton och Ice Bucket Challenge ett humoristiskt och positivt laddat budskap - båda om smärtsamma ämnen. Eftersom de båda blev virala visar resultatet att det viktigaste är ett känslomässigt laddat budskap som påverkar folk, oavsett om det är glada, ilskna eller sorgsna känslor. Det krävs stark känslomässig påverkan för att personer ska känna sig motiverade att sprida vidare ett budskap. Samhällsklimatet och aktuella samhällsfrågor kan hjälpa en kampanj bli viral, men är inte nödvändig. Det finns ingen specifik riktlinje eller mall att följa för att bli viral, men det är viktigt att ha hög spridbarhet på sitt budskap och motivera mottagaren att dela vidare.

Thesis (DLitt (Ancient Studies))--University of Stellenbosch, 2006. / This study accounts for the forms and functions of the similes in the Book of Hosea. It proposes new tools for textual criticism, biblical interpretation, and understanding Biblical Hebrew (BH) worldview. Chapter One presents the task we have chosen for ourselves, its nature, some obstacles from other areas of scholarship, and the foundational notions of embodiment and Prototype Theory. Chapter Two presents principles drawn from Cognitive Semantics and Cognitive Syntax. A weakened version of the Lakoff-Johnson conceptual metaphor theory is adopted, and the key notions of embodiment and judgments of prototypicality are presented. Elements of Conceptual Blending are presented and adapted for simile analysis. Finally, text-based differences between metaphors and similes are discussed. Chapter Three presents cognitive cultural constructs of Strauss and Quinn: cultural schemas, cultural exemplars, cultural models, and cultural themes. Strauss and Quinn’s conclusions about metaphors’ use in everyday speech are shown to agree with our postulation of speaker assessment of the hearer’s ability to process utterances before they are produced. This postulation allows us to erect one part of a theory of simile. Chapter Three then integrates metaphor with the Strauss-Quinn cultural meaning model, and then with Boroditsky’s Weak Structuring view of metaphor. The effect is to provide a reasonable basis, amenable to empirical investigation, for the investigation of both metaphor and simile. Finally, the notions of embodiment and prototypicality are applied to the Strauss-Quinn model. Chapter Four presents various assumptions and conclusions that are later used to analyze Hosea’s similes. These include: (1) elements of Floor’s (2004a) model of Information Structure for BH narrative, with modifications and additions for poetry; (2) three cognitive types of similes in Hosea, posited for working purposes; (3) an adaptation of the conceptual blending apparatus to similes; (4) hypotheses to account for the distribution of similes versus that of metaphors in BH poetry, and to account for patterned differences in how various kinds of concepts are combined and manipulated; (5) an integration of these patterns with the three simile types; and (6) correlation of the cultural constructs of cultural schema, cultural theme, and cultural model with Hosea’s similes and metaphors. Chapter Five presents a number of scholarly views of the Book of Hosea, and characterizes the principal authorities cited in the next chapter. Chapter Six deductively applies all the foregoing theory to an examination of Hosea’s similes. Other observations are made inductively: (1) kinaesthetic image schemas’ role in Hosea’s poetry; (2) systematic difference in the use of similes versus metaphors in image elaboration; and (3) Information Structure’s role in simile analysis. Chapter Seven summarizes this study’s research and conclusions concerning, e.g., (1) the criteria for accounting for the embodiment and judgments of prototypicality characterizing Hosea’s similes; (2) the dependence of Hosea and his audience upon knowledge of themselves and their environment for their view of YHWH; and (3) the aid brought by a cognitive theory of similes in the task of textual criticism. Chapter Eight discusses prospects for further research and possible implications for translating Hosea’s similes and metaphors.

Demand for electrical power is increasing everyday. Along with the increase in power demand, the characteristics of the loads are also changing. From being high power consuming, simple, robust loads, today loads are more efficient, but at the same time more sensitive. The performance and life of these highly sensitive loads depend a lot on the quality of power supplied to them. <p>Power quality is any deviation of the voltage or current waveform from its normal sinusoidal waveshape. These disturbances include, but are not limited to, sag, undervoltage, interruption, swell, overvoltage, transients, harmonics, voltage flicker and any other distortions to the sinusoidal waveform. Occurrence of one or more of such disturbances is called a power quality event. Automatic classification of these disturbances is important for quick determination of the causes and to characterize possible impacts of the disturbances.<p>Modern microprocessor based protective relays have numerous integrated functions that allow them to provide information on power quality events. It is proposed to utilize the existing numerical relays to analyze the quality of power at any point in the power system. The numerical relays can be programmed to capture the oscillographic waveform or any disturbance on the analogue signal or change of state of the digital signals and store it in the form of Common Format For Transient Data Exchange (COMTRADE) format. These records are then transferred to a central monitoring workstation for off-line analysis. <p>This thesis describes a technique to automate the classification and analysis of the power quality events using relay recorded data. The technique uses voltage duration and magnitude (as specified in the IEEE Std. 1159 - 1995, IEEE Recommended Practice for Monitoring Electric Power Quality) of three phases to detect and classify the events. The classified results are then presented in a user-friendly graphical form. Fast Fourier Transform (FFT) is used to estimate the fundamental frequency and harmonic components in power systems. The graphical user interface of the power quality analysis tool is developed using Microsoft Visual C++ IDE and the algorithms are programmed in C++. <p>The proposed technique was tested using data obtained by simulating different power system disturbances as well as on the data recorded by relays. The algorithms were able to classify the power quality events accurately. In the future, this facility will: enhance the real time monitoring of power quality and provide statistical analysis of available power quality data. From the utility viewpoint, it would allow them to monitor power quality in a cost effective manner and assist in preventive and predictive maintenance besides helping them to fix differential tariff based on the quality of the delivered power. It may also turn out to be a smart tool for them to penalize the consumer polluting the power quality.
