SUmmaries in Afrikaans and English / Text in Afrikaans / Die oogmerk van hierdie verhandeling is om te wys op die tekstuele en visuele kontraste in Georgi con 11.1 - 108. Ten aanvang word 'n bree vergelyking getreftussen Georgicon I en II om sodoende die funksie asook die effek van Boek 2 in die viertal gedigte te bepaal. Vir 'n meer indringende ontleding word Boek 2, asook die relevante verse, skematies verdeel en alhoewel die panoramiese effek versteur word, kan die problematiek van hierdie gedig alleenlik s0 noukeuriger opgelos word. Daar word getoon dat Boek 2 in drie afdelings verdeel is met 'n laus-tema wat telkens as hoogtepunt dien vir elk van die dele. Ook die oorkoepelende tema van variatio-labor en die wisselwerking daarvan kan duideliker waargeneem word. Verse I - I 08 is didakties van aard en eenvoudige patrone word saamgestel uit alledaagse objekte en idees. Vergilius slaag daarin om vergelykings af te dwing en om kontras te bewerkstellig deur die skep van imagines. Hierdie beelde kom duideliker na vore deur 'n baie noukeurige analise van die teks en s6 word vorm, lyn, kleur en tekstuur beklemtoon en gekontrasteer. W anneer die fokus verskuif vanaf die natuur na die mens, word daar gewys op die kontras in verse 3 5 - 46 tussen die landbouers en die politieke magsfiguur van Maecenas. Die onderliggende felix I fortuna/us tema word s6 beklemtoon. Die problematiek van didaktisisme word aangespreek deur die effek van die kontrastering van parallelle passasies aan te toon. As Leitmotiv word telkens gewys op die tekstuele en visuele kontraste in die digter se keuse en rangskikking van 'n ryke verskeidenheid van borne - met spesifieke verwysing na hulle aard, voorkoms, herkoms en funksie. / The aim of this dissertation is to indicate the textual and visual contrasts in Georgi con TI.l - 108. In a broad comparison between Georgica I and II the function and the effect ofBook 2 within the framework of the four poems is determined. With a view to a more penetrating analysis, Book 2 as a whole and specifically lines 1 - 108 will be dealt with schematically. Although this puts the panoramic effect at risk, it is the only way in which the complexities of this poem can be successfully resolved. Book 2 is shown to have a tripartite structure, with a taustheme as the climax of each of the three divisions. The over-arching theme of reciprocating variatio- labor also comes to light more clearly. Lines I - I 08 are of a didactic nature, and simple patterns are shaped out of everyday objects and ideas. By creating imagines Vergil manages to enforce comparisons and to bring about contrasts. A meticulous analysis of the text highlights these images more clearly and in this manner the poet accentuates colour, form, line and texture. When the focus shifts from nature to man, the contrast between the farmers and the politically powerful Maecenas in lines 3 5 - 46 is brought to the fore to emphasize the underlying theme of felix I fortunatus. The problem of didacticism is addressed by focusing on the effect of the contrasts between parallel passages. The textual and visual contrasts in the poet's choice and marshalling of a rich variety of trees, with a particular reference to their nature, occurrence, provenance and function, serve as Leitmotif for the dissertation as a whole. / Classics and Modern European Languages / M.A. (Latyn)

[pt] Esta tese propõe uma reflexão, à luz das Escrituras Sagradas e da fé cristã, sobre a inovadora proposta para a Teologia da Libertação de Rubem Alves. Inicialmente, discute-se a Teologia Latino-Americana da Libertação (TdL), tentando investigar seus influxos das Ciências do Social (CdS), as quais forneceram o ferramental necessário para abordar o concreto-pensado sobre o qual a TdL teologizou. Pretende-se mostrar como Rubem Alves abriu mão de uma gramática marxista (realidade penúltima) e assumiu uma linguagem mais abrangente, humanista, interdisciplinar e holística sobre a liberdade e essência humana mediante uma interpretação inovadora de não apenas textos bíblicos e evangélicos, mas também de muitos poetas, teólogos, filósofos e uma gama ampla de outros pensadores sociais. A partir do diálogo interdisciplinar e suas próprias inquietudes e vivências dolorosas, Rubem Alves centralizou o corpo como a prioridade axiológica de seu que-fazer teológico da Libertação. Finalmente, propõe-se uma Teologia lúdica da Libertação mais integral, poética e transcendente a partir do método pastoral tripartido ver-julgar-agir que, além de levar em conta a multidimensionalidade e complexidade da essência humana que o corpo expressa, assume uma linguagem mais dionisíaca e polifônica na busca pela libertação humana não só da servidão econômica, mas de todas as formas de repressão. / [en] This dissertation posits a scriptural and Christian faith-based reflection on Brazilian theologian Rubem Alves innovative Liberation Theology proposal. Initially, we examine Latin American Liberation Theology (abbreviated TdL herein) and attempt to trace how it was influenced by the Social Sciences (abbreviated CdS herein) which supplied Liberation Theology with the necessary tools for theologizing the thought concrete. We aim to show how Rubem Alves cast off a Marxist grammar (penultimate reality) in lieu of a broader, more humanistic, interdisciplinary and holistic discourse regarding human freedom and personhood by innovatively interpreting not only Biblical and Gospel texts but also those of poets, theologians, philosophers and a wide range of other social thinkers. From his interdisciplinary dialogs, his personal soul-searching and painful life experiences, Alves centered the body as the axiological priority of his Liberation Theology undertaking. Finally, we propose a more holistic, poetic, playful and transcendental Liberation Theology based on the threefold see-judge-act pastoral process that, beside focusing on the multidimensional and complex human personhood the body expresses, incorporates a more Dionysian and polyphonic discourse in its search for not only human economic freedom, but freedom from all forms of repression. / [es] En esta tesis, se propone una reflexión a la luz de las Sagradas Escrituras y de la fe cristiana sobre la innovadora propuesta de la Teología de la Liberación del teólogo brasileño Rubem Alves. Se analiza primero la Teología de la Liberación en América Latina (aquí abreviada como TdL), tratando de investigar la influencia que sufrió de las Ciencias Sociales (aquí abreviadas como CdS), las cuales le prestaron las herramientas necesarias para teologizar sobre lo concreto-pensado. Se pretende mostrar cómo Rubem Alves abandonó una gramática marxista (penúltima realidad) y asumió un lenguaje humanista, interdisciplinario e integral más amplio sobre la libertad humana mediante una interpretación innovadora, no sólo de los textos bíblicos y evangélicos, sino de muchos poetas, teólogos, filósofos y una amplia gama de otros pensadores. Desde el diálogo interdisciplinario y sus propias inquietudes y experiencias dolorosas, Alves centró al cuerpo como la prioridad axiológica de su Teología de la Liberación. Por último, se propone una Teología de la Liberación más integral, poética, trascendente y lúdica a partir del método pastoral tripartito ver-juzgar-actuar que, además de tomar en cuenta la multidimensionalidad y complejidad de la esencia humana que el cuerpo expresa, se vale de un lenguaje más dionisíaco y polifónica en la búsqueda de la liberación humana no sólo de la servidumbre económica, sino de todas las formas de represión.

A numerical treatment of non-linear higher-order geometric evolution equations with the level set and the finite element method is presented. The isotropic, weak anisotropic and strong anisotropic situation is discussed. Most of the equations considered in this work arise from the field of thin film growth. A short introduction to the subject is given. Four different models are discussed: mean curvature flow, surface diffusion, a kinetic model, which combines the effects of mean curvature flow and surface diffusion and includes a further kinetic component, and an adatom model, which incorporates in addition free adatoms. As an introduction to the numerical schemes, first the isotropic and weak anisotropic situation is considered. Then strong anisotropies (non-convex anisotropies) are used to simulate the phenomena of faceting and coarsening. The experimentally observed effect of corner and edge roundings is reached in the simulation through the regularization of the strong anisotropy with a higher-order curvature term. The curvature regularization leads to an increase by two in the order of the equations, which results in highly non-linear equations of up to 6th order. For the numerical solution, the equations are transformed into systems of second order equations, which are solved with a Schur complement approach. The adatom model constitutes a diffusion equation on a moving surface. An operator splitting approach is used for the numerical solution. In difference to other works, which restrict to the isotropic situation, also the anisotropic situation is discussed and solved numerically. Furthermore, a treatment of geometric evolution equations on implicitly given curved surfaces with the level set method is given. In particular, the numerical solution of surface diffusion on curved surfaces is presented. The equations are discretized in space by standard linear finite elements. For the time discretization a semi-implicit discretization scheme is employed. The derivation of the numerical schemes is presented in detail, and numerous computational results are given for the 2D and 3D situation. To keep computational costs low, the finite element grid is adaptively refined near the moving curves and surfaces resp. A redistancing algorithm based on a local Hopf-Lax formula is used. The algorithm has been extended by the authors to the 3D case. A detailed description of the algorithm in 3D is presented in this work. / In der Arbeit geht es um die numerische Behandlung nicht-linearer geometrischer Evolutionsgleichungen höherer Ordnung mit Levelset- und Finite-Elemente-Verfahren. Der isotrope, schwach anisotrope und stark anisotrope Fall wird diskutiert. Die meisten in dieser Arbeit betrachteten Gleichungen entstammen dem Gebiet des Dünnschicht-Wachstums. Eine kurze Einführung in dieses Gebiet wird gegeben. Es werden vier verschiedene Modelle diskutiert: mittlerer Krümmungsfluss, Oberflächendiffusion, ein kinetisches Modell, welches die Effekte des mittleren Krümmungsflusses und der Oberflächendiffusion kombiniert und zusätzlich eine kinetische Komponente beinhaltet, und ein Adatom-Modell, welches außerdem freie Adatome berücksichtigt. Als Einführung in die numerischen Schemata, wird zuerst der isotrope und schwach anisotrope Fall betrachtet. Anschließend werden starke Anisotropien (nicht-konvexe Anisotropien) benutzt, um Facettierungs- und Vergröberungsphänomene zu simulieren. Der in Experimenten beobachtete Effekt der Ecken- und Kanten-Abrundung wird in der Simulation durch die Regularisierung der starken Anisotropie durch einen Krümmungsterm höherer Ordnung erreicht. Die Krümmungsregularisierung führt zu einer Erhöhung der Ordnung der Gleichung um zwei, was hochgradig nicht-lineare Gleichungen von bis zu sechster Ordnung ergibt. Für die numerische Lösung werden die Gleichungen auf Systeme zweiter Ordnungsgleichungen transformiert, welche mit einem Schurkomplement-Ansatz gelöst werden. Das Adatom-Modell bildet eine Diffusionsgleichung auf einer bewegten Fläche. Zur numerischen Lösung wird ein Operatorsplitting-Ansatz verwendet. Im Unterschied zu anderen Arbeiten, die sich auf den isotropen Fall beschränken, wird auch der anisotrope Fall diskutiert und numerisch gelöst. Außerdem werden geometrische Evolutionsgleichungen auf implizit gegebenen gekrümmten Flächen mit Levelset-Verfahren behandelt. Insbesondere wird die numerische Lösung von Oberflächendiffusion auf gekrümmten Flächen dargestellt. Die Gleichungen werden im Ort mit linearen Standard-Finiten-Elementen diskretisiert. Als Zeitdiskretisierung wird ein semi-implizites Diskretisierungsschema verwendet. Die Herleitung der numerischen Schemata wird detailliert dargestellt, und zahlreiche numerische Ergebnisse für den 2D und 3D Fall sind gegeben. Um den Rechenaufwand gering zu halten, wird das Finite-Elemente-Gitter adaptiv an den bewegten Kurven bzw. den bewegten Flächen verfeinert. Es wird ein Redistancing-Algorithmus basierend auf einer lokalen Hopf-Lax Formel benutzt. Der Algorithmus wurde von den Autoren auf den 3D Fall erweitert. In dieser Arbeit wird der Algorithmus für den 3D Fall detailliert beschrieben.

The implications of gait disorder, muscle weakness, and spinal cord injuries for work and age-related mobility degradation have increased the need for rehabilitation exoskeletons. Specifically, the hip rehabilitation exoskeletons due to a high percentage of the mechanical power is generated by this join during the gait cycle. Additionally, the prolonged hospitalisation after hip replacement and acetabular surgeries that affect human mobility, the social-economic impacts and the quality of life. For these reasons, a hip rehabilitation exoskeleton was our focus in this research, as it will contribute being a sustainable solution to take over the burden of physiotherapy and let patients perform their rehabilitation at home or outdoors.  This thesis details an approach of creating a hip rehabilitation exoskeleton, starting with modelling, simulating, and controlling the rehabilitation hip joint in a based-simulation environment. The mathematical model and the reason for using a series elastic actuator in the hip joint to execute the movement in a sagittal plane are more detailed. Because trajectory tracking is commonly used for controlling rehabilitation exoskeletons to ensure safe and reliable motion tracking methods; therefore, two desired torque signals were tested and analysed with the optimal linear quadratic regulator (LQR). The experiments were performed using two torque signals of a healthy hip joint—representing the sit-to-stand (STS) and the walking activity for their importance in lower limb movements. However, the mathematical model used as a basis of the optimal control strategy is usually influenced by multiple sources of uncertainties. Therefore, four case studies of various optimal control strategies were tested for a twofold reason: to choose the most optimal control strategy, and to test the energy consumption of these cases during the STS and walking movements, because the long-term goal is to produce a lightweight and reliable rehabilitation hip exoskeleton. The research showed compelling evidence that tuning the control strategy will not influence the robustness of an optimal controller only, but affect the energy consumption during the STS and walking activity, which needs to be considered in exoskeleton control design regarding its applications. / Behovet av exoskelett för rehabilitering har ökat p.g.a. komplikationer som uppstår vid arbete och åldersrelaterad försämring. Komplikationerna består bland annat av gångstörning, muskelsvaghet och ryggmärgsskador. Speciellt höftexoskelett avsett för rehabilitering är extra intressant på grund av att rehabilitering inom detta område omfattar långvarig sjukhusvistelse efter höftprotes- och acetabulära operationer. Höftleden är en av de leder som utsätts för relativt höga mekaniska påfrestningar och minskad rörelseförmåga leder inte sällan till socioekonomiska effekter och minskad livskvalité. Av denna anledning kommer höftexoskelett för rehabilitering vara det primära området i denna avhandling då det kommer att vara en lösning för att minska belastningen inom sjukvård och låta patienter utföra sin rehabilitering hemma på egen hand. Denna avhandling beskriver en metod för att skapa ett höftexoskelett avsett för rehabilitering med början i modellering, simulering och kontroll av en höftled av exoskelett i en simuleringsmiljö. Genom att använda ett serieelastiskt manöverdon för att utföra en höftledsrörelse i ett sagittalt så uppnås en mer detaljerad matematisk modell. Genom att använda banspårning, som vanligtvis används för att kontrollera exoskelett för rehabilitering för att säkerställa säkra och pålitliga rörelsespårningsmetoder, så analyserades två vridmomentssignaler mot en linjär kvadratisk regulator (LQR). Simuleringarna utfördes med hjälp av två vridmomentsignaler som representerar sitt-till-stå (STS) och gångaktivitet hos en frisk höftled. Den matematiska modellen som används för att hitta den optimala kontrollstrategin påverkas vanligtvis av flera osäkerhetskällor. Därför testades fyra fallstudier av olika optimala kontrollstrategier för två skäl: den ena för att välja den mest optimala kontrollstrategin emellan och den andra för att mäta energiförbrukningen för dessa STS och gångrörelse så att vi kan producera ett lätt och pålitligt höftexoskelett avsett för rehabilitering. Forskningen visar övertygande bevis för att inställning av styrstrategin inte bara kommer att påverka robustheten hos en optimal styrenhet utan även påverkar energiförbrukningen under STS och gångaktivitet vilket måste beaktas vid design av exoskelett.
