In this thesis, a new approach combining neural networks and genetic algorithms is presented for microwave design. In this method, an accurate neural network model is developed from the experimental data. This neural network model is used to perform sensitivity analysis and derive response surfaces. An innovative technique is then applied in which genetic algorithms are coupled with the neural network model to assist in synthesis and optimization. The proposed method is used for modeling and analysis of circuit parameters for flip chip interconnects up to 35 GHz, as well as for design of multilayer inductors and capacitors at 1.9 GHz and 2.4 GHz. The method was also used to synthesize mm wave low pass filters in the range of 40-60 GHz. The devices obtained from layout parameters predicted by the neuro-genetic design method yielded electrical response close to the desired value (95% accuracy). The proposed method also implements a weighted priority scheme to account for tradeoffs in microwave design. This scheme was implemented to synthesize bandpass filters for 802.11a and HIPERLAN wireless LAN applications in the range of 5-6 GHz. This research also develops a novel neuro-genetic design centering methodology for yield enhancement and design for manufacturability of microwave devices and circuits. A neural network model is used to calculate yield using Monte Carlo methods. A genetic algorithm is then used for yield optimization. The proposed method has been used for yield enhancement of SiGe heterojunction bipolar transistor and mm wave voltage-controlled oscillator. It results in significant yield enhancement of the SiGe HBTs (from 25 % to 75 %) and VCOs (from 8 % to 85 %). The proposed method is can be extended for device, circuit, package, and system level integrated co-design since it can handle a large number of design variables without any assumptions about the component behavior. The proposed algorithm could be used by microwave community for design and optimization of microwave circuits and systems with greater accuracy while consuming less computational time.

Text in Afrikaans / Summaries in English and Afrikaans / The purpose of the study was to determine the contribution Edu-K can make to the way that people are able to actualise themselves. Two literature studies were done. The first literature study dealt with the existing theories on self actualisation. After this study a list was drawn up that consisted of the characteristics of the actualiser. The second literature study dealt with the Seven Dimensions of Intelligence, as described by Edu-K. A connection was drawn between the characteristics of the actualiser and the Seven Dimensions. A clear connection was drawn theoretically between the characteristics of the actualiser and the seven dimensions. The empirical study also shows an improvement in the academical performance as well as the characteristics of the actualiser. / Die doel van hierdie studie is om te bepaal watter bydrae Edu-Kinesiologie (Edu-K) kan lewer tot die bereiking van selfaktualisering, veral op akademiese gebied Vir die verkenning is twee literatuurstudies gedoen. Die eerste literatuurstudie het gehandel oor die teoriee wat bestaan oor selfaktualisering. Na hierdie studie is 'n vraelys oor eienskappe wat kenmerkend van selfaktualiseerders is, saamgestel. Die tweede literatuurstudie het gegaan oor die Sewe Dimensies van lntelligensie wat deur Edu-K beskryf word, en daar is 'n verband getrek tussen die Sewe Dimensies en die eienskappe van selfaktualisering. Daar is teoreties 'n duidelike verband getrek tussen selfaktualisering en die Sewe Dimensies van lntelligensie. Die empiriese studie het ook aan die lig gebring dat daar 'n verbetering in akademiese prestasie, sowel as eienskappe van selfaktualisering is na terapie. / M. Ed.(Guidance and Counselling)

Different areas of science have studied the co-reference for its relevance to the local coherence, as well as to the discourse comprehension. However, a crucial question remains and requires to be clarified, that is about the cognitive mechanisms and the linguistics principles that underlie the choice of anaphora among the various forms of the language. The current work has its theoretical connection with Experimental Psycholinguistics which deals with the process of the phases, and more especifically with the processing of the co-reference. This work compares the efficiency of the lexical pronouns vs. repeated-name, as well as hiperonimos vs. hiponimos, both seen as ways of one's inter-sentential anaphoric recalling in Brazilian Portuguese. It was also verified that the wide range of the Centering Theory (Grosz, Joshi e Weinstein, 1983, 1995), which states a slower effect known as Repeated NP Penalty when recalling an antecedent using the repeated noun instead of a pronoun, as well as the The Informational Load Hypotheses (Almor 1990, 1999, 2000), as an alternative concept that connects the processing cost with the discourse function. For that, the current research used three on-line self paced reading experiments and analyzed its results by using both the T-Test and the ANOVA one. In the first experiment the lexical pronouns were read faster than the repeated pronouns, in accordance to the Centering Theory and the he Informational Load Hypotheses. The second experiment, the co-reference was better established by the hiperônimos instead of hipônimos, reinforcing the cost-funcion principle stated by Almor (1990, 1999, 2000), while the Repeated NP Penalty by Gordon et. al. (1993, 1995), is concerned about the dichotomy between lexical pronouns vs repeated nouns. The syntactic prominence was also discussed in Chamber's & Smith (1999) research as well as in Leitão's (2005), but the third experiment stated the independent act of the syntactic prominence in relation to the type of the anaphora, even though that does not exclude the influence of the structural parallelism. / A co-referência é cornumente definida como uma estratégia de progressão textual e caracterizada pela retomada de urna entidade prévia, também denominada antecedente, através de urna anáfora. Ela vem sendo estudada por várias áreas do conhecimento científico, devido a sua importância para a coerência local e, conseqüentemente, para a compreensão do discurso, mas uma questão crucial continua em aberto e requer maiores esclarecimentos: quais os mecanismos cognitivos e os princípios lingüísticos que subjazem a escolha da anáfora, entre a multiplicidade de formas existente na língua. O presente trabalho se insere no quadro teórico da Psicolingüística Experimental que trata do processamento de frases e, mais especificamente, do processamento da co-referência. Nele, compararnos a eficiência dos pronomes lexicais vs. nomes repetidos e dos hiperônimos vs. hipônimos, como formas de retomada anafórica inter-sentencial do sujeito em Português Brasileiro. Verificamos também a abrangência explicativa da Teoria da Centralização (Grosz, Joshi e Weinstein, 1983, 1995), que postula urn efeito de retardamento, mais conhecido corno Penalidade do Nome Repetido, ao retomar um antecedente proeminente sintaticamente usando urn nome repetido em vez de urn pronome, e da Hipótese da Carga Informacional (Almor 1990, 1999, 2000), com uma concepção alternativa que relaciona o custo de processarnento e atenção discursiva. Para isso, aplicamos três experimentos on-line de leitura auto-monitorada e validamos estatisticamente seus resultados através do Teste-T e da ANOVA. No primeiro experimento, os pronomes lexicais foram lidos mais rapidamente do que os names repetidos, em consonância corn a Teoria da Centralização e com a Hipótese da Carga Informacional. No segundo experimento, a co-referenda foi estabelecida rnais facilrnente pelos hiperônimos do que pelos hipônimos, ratificando o principio de otimização entre custo de processarnento e função discursiva, defendido por Almor (1990, 1999, 2000), enquanto a Penalidade do Nome-Repetido, constatada pioneiramente por Gordon et. al. (1993, 1995), limita-se a dicotornia pronornes lexicais vs. nomes repetidos. A proeminência sintática também foi questionada no estudo de Chambers e Smith (1999) em Inglês e de Leitão (2005) em Português Brasileiro, mas o terceiro e último experirnento comprovou sua atuação independente do tipo de anáfora, apesar de não descartar a influência do paralelismo estrutural.

João I e na Crônica de D. Fernando, de autoria do autor lusitano Fernão Lopes, e na Crônica do Condestável, de autor anônimo. Diante do desafio de se consolidar e legitimar no poder, os reis avisinos e a nova nobreza que com os mesmos ascende, promoveram uma propaganda política, por meio de representações dos seus maiores personagens, visando a construção de imagens paradigmáticas. Esses heróis, exemplos morais e modelos de conduta, fortaleceram tanto a nova dinastia, quanto as novas casas senhoriais, no jogo político da corte, onde a centralidade monárquica e a hierarquização dos espaços ganhavam força. Nuno Álvares Pereira emerge destes escritos como o nobre/cavaleiro ideal, personificando atributos, como lealdade, fidelidade e piedade, provenientes do ideal cavaleiresco-cristão, ganhando novos significados no bojo do projeto centralizador da monarquia avisina. A análise das características marcantes deste cavaleiro/nobre exemplar sugere a promoção - por meio de instrumentos simbólicos e ideológicos do poder, de novas forças sociais, que ascendem ao espaço da corte régia, fortalecendo a noção de um novo súdito, incondicionalmente fiel ao soberano lusitano. / The aim of this work is to analyze the memorialization accomplished during the first reigns of the Avis Dynasty, with emphasis on the Crônica de D. João I and the Crônica de D. Fernando, by Lusitanian author Fernão Lopes, and on the Crônica do Condestável, by an unknown author. Facing the challenge of consolidating and legitimizing their power, the Avis kings and the new nobility that ascended to power with them made use of political propaganda through the representation of their major personages, in order to produce paradigmatic images. Through these real heroes, who served as moral examples and role models, the kings, as well as the new nobility, strengthened their positions in the political game of the court, where the concentration of power by the monarchy and the hierarchization of spaces were increasingly prevalent. Nuno Álvares Pereira emerges from these writings as the ideal nobleman/knight, personifying attributes such as loyalty, fidelity and piety pertaining to the chivalrous Christian ideal, gaining a new significance within the centralizing project of the Avis monarchy. The analysis of the major features of this exemplary nobleman/knight suggests the promotion – through symbolic instruments, genuine ideological bases of power - of new social forces that, up to then, had little or no access to space in the royal court, strenghthening the notion of a subject unconditionally loyal to his sovereign.

Bayesian inference for stochastic volatility models using MCMC methods highly depends on actual parameter values in terms of sampling efficiency. While draws from the posterior utilizing the standard centered parameterization break down when the volatility of volatility parameter in the latent state equation is small, non-centered versions of the model show deficiencies for highly persistent latent variable series. The novel approach of ancillarity-sufficiency interweaving has recently been shown to aid in overcoming these issues for a broad class of multilevel models. In this paper, we demonstrate how such an interweaving strategy can be applied to stochastic volatility models in order to greatly improve sampling efficiency for all parameters and throughout the entire parameter range. Moreover, this method of "combining best of different worlds" allows for inference for parameter constellations that have previously been infeasible to estimate without the need to select a particular parameterization beforehand. / Series: Research Report Series / Department of Statistics and Mathematics

MBSE-Model-Based Systems Engineering wird als vielversprechender Ansatz gesehen, die steigende Komplexität heutiger Produktentwicklungsprozesse beherrschbar zu machen. Bei der Einführung und Umsetzung von MBSE existieren jedoch hohe Einstiegshürden, insbesondere, wenn formale Modellierungssprachen wie SysML für Modellierungsaktivitäten verwendet werden. Gleichzeitig bieten formale Modellierungssprachen jedoch Vorteile bei der Ermöglichung einer domänenübergreifenden Kommunikation und dem Informationsaustausch. Dieser Beitrag beschreibt einen Ansatz zur nutzer- und aufgabengerechten Unterstützung von Modellierungsaktivitäten mittels formaler Modellierungssprachen im Kontext des MBSE. Ziel des Ansatzes ist es, die Modellierung auf die Bedarfe und Aufgaben einzelner Anwender bzw. deren Rolle im Produktentwicklungsprozess zu fokussieren und somit einen gezielteren Zugang zur Modellierung zu ermöglichen. Hierzu werden Ansätze aus dem Bereich Architekturframeworks zur Strukturierung von Modellen mittels Bedarfs-getriebener Sichten mit einer Aktivitäts-getriebenen Formalisierung von Methoden des MBSE kombiniert. Methoden des MBSE werden in einzelne Modellierungsaktivitäten unterteilt und diese mit Sichten aus einem Architekturframework, die die Modellierungsaktivität unterstützen, verknüpft. Somit wird einerseits eine klare Strukturierung des Modells nach Sichten und andererseits eine gezielte und eindeutige Durchführung bedarfsgerechter Methoden des MBSE ermöglicht.

Last years, lead time, flexibility, cost, and quality have become significant factors for the manufacturing industry. This also applies to gears, which could be manufactured using hobbing and grinding. Fixing systems are used to precisely center and fully fix gears to reach high quality. These are expensive and not flexible which requires a new one for each gear dimension. This limits the production of prototypes and so new product for the market. Developing a 3D concept for affordable and flexible fixing is the purpose. Through literature research, analyzing the current process, discussions with the company, desk research, and benchmarking, requirements are made for the new concept. Then brainstorming sessions are done to come up with new concepts. The concepts are analyzed, discussed with the company, and combined into two better concepts. Even though the higher flexibility of the other concept, the robustness of the winning concept “CoNut”. The principle is that only a few parts have to be changed instead of the whole system. The concept is further developed in 3D, where design for cost and manufacturing are applied. Finally, test procedures are drafted to validate the concept against therequirements. While some require a prototype, others are already validated by using the 3D model. Ultimately, an affordable and more flexible fixing system is developed as a 3D concept, by using a structural design process, which is likely to meet all the requirements. Since the model is cheaper and easier to change within meeting the other requirements, the purpose is reached.

The aim of this thesis is to introduce BMC approach in relation to other body-oriented psychotherapies, to characterise its principles and techniques, the format of therapy and to analyze and assess it from a point of view of the basic questions of scientific validity of a psychotherapeutic modality. Further in this thesis we summarize the bodily anchored experiencing theory. The empirical part of this thesis is a quantitative study of relation of body awareness, depressive experiencing and the satisfaction with life. We also studied a relationship among body awareness and socio-demographical characteristics of respondents. We ascertained some statistically significant correlations pointing towards a link between the ability of body awareness and depressive experiencing and also with satisfaction with life. The findings of this empirical study point towards the usefulness of further systematical developing of the body awareness construct.

O objeto desta pesquisa é, portanto, o corpo e suas experiências intensivas a partir de experimentações no campo da educação somática. Para tanto o presente estudo se aproxima de duas abordagens somáticas, os Bartenieff Fundamentals™ e o Body Mind Centering™. O intuito foi perceber como estas abordagens possibilitam, a partir dos processos de desconstrução e reconstrução corpórea, aquilo que Antonin Artaud chamou corpo sem órgãos, entendendo-o não como um conceito, mas sim, como uma prática. A partir deste estudo foi possível reconhecer uma grande afinidade entre as proposições artaudianas em torno da arte e da vida e as proposições metodológicas das abordagens somáticas aqui pesquisadas. Para tanto, pesquisou-se a radicalidade da obra de Antonin Artaud e sua conseqüência no campo das artes cênicas a partir da análise de seus textos e de pensadores que contribuíram para o entendimento do corpo sem órgãos, especialmente Gilles Deleuze e Félix Guattari. Em seguida, foram analisadas as especificidades e características em comum, princípios e fundamentos das propostas metodológicas referentes às abordagens somáticas citadas. Tendo em vista o caráter prático-teórico deste estudo, uma pesquisa de campo foi realizada por meio de experimentações práticas das respectivas abordagens em Laboratórios, além de entrevistas com profissionais das artes cênicas envolvidos com a prática somática. Num último momento foram transversalizados os arcabouços práticos e teóricos levantados pelo presente estudo. Através dos resultados obtidos a partir deste arcabouço prático-teórico é possível afirmar que a experimentação somática dos Bartenieff Fundamentals™ e do Body Mind Centering™ no âmbito das artes cênicas entrelaça vida e arte, reconfigurando o fazer artístico em sua potência vital e a própria vida enquanto obra de arte, tal qual preconizou Antonin Artaud. / This research argues concepts and methodological proposals that approach the theoretical and practical study concerning the body understanding it while the expressive subject in constant mutation and process of reinvention. The object of this research is, therefore, the body and its intensive experiences from experiments in the field of somatic education. For this reason, the study approximates two somatic approaches, the Bartenieff Fundamentals™ and Body Mind Centering™. The aim was to perceive how these somatic approaches allow, from the processes of corporal deconstruction and reconstruction, what Antonin Artaud called body without organs, perceiving it not as a concept, but as practical one. From this study it was possible to recognize a great affinity between the artaudians propositions about art and life and the methodological proposals of somatic approaches surveyed here. To this end, we inquired the radical work of Antonin Artaud and its consequence in the field of scenic arts from the analysis of their texts and thinkers who contributed to the understanding of the body without organs, especially Gilles Deleuze and Félix Guattari. After that, we analyze the features and characteristics in common, principles and foundations of the methodological proposals concerning the somatic approaches that had been cited. Given the character practical-theoretician of this study, a field survey was carried out through practical trials of approaches in laboratories, as well as interviews with performing arts professionals involved with the somatic practice. At the last moment, it was interrelated the practical and theoretical frameworks raised by this study. With the results obtained from this theoretical-practical framework was possible to assert that the trial of somatic Bartenieff Fundamentals™ and Body Mind Centering™ within the performing arts weaves life and art, reconfiguring the artistic making in its vital power and life as a work of Art, like praised Antonin Artaud.
