TY - THES A1 - Le, Ha Thanh T1 - Behaviour of Rice Husk Ash in Self-Compacting High Performance Concrete N2 - The main objective of this thesis is to investigate the characteristics of rice husk ash RHA) and then its behaviour in self-compacting high performance concrete (SCHPC) with respects to rheological properties, hydration and microstructure development and alkali silica reaction, in comparison with silica fume (SF). The main results show that the RHA is a macro-mesoporous amorphous siliceous material with a very high silica content comparable with SF. The pore size distribution is the most important parameter of RHA besides amorphous silica content. This parameter affects pore volume, specific surface area, and thus the water demand and the pozzolanic reactivity of RHA and its behaviour in SCHPC. The incorporation of RHA decreases filling and passing abilities, but significantly increases plastic viscosity and segregation resistance of SCHPC. Therefore, RHA can be used as a viscosity modifying admixture for SCHPC. The incorporation of RHA increases the superplasticizer adsorption, the superplasticizer saturation dosage, yield stress and plastic viscosity of mortar. Fresh mortar formulated from SCHPC is a shear-thickening material. The incorporation of RHA/SF ecreases the shearthickening degree. The incorporation of RHA/SF increases the degree of cement hydration. SF appears more effective at 3 days possibly due to the better nucleation site effect, whereas RHA dominates at the later ages possibly due to the internal water curing effect. The incorporation of RHA/SF increases the degree of C3S hydration, particularly the C3S hydration rate from 3 to 14 days. The pozzolanic reaction takes place outside and inside RHA particles. The internal pozzolanic eaction products consolidate the pores inside RHA particles rather than contribute to the pore refinement in the cement matrix. In the presence of the high alkali concentration, RHA particles act as microreactive aggregates and react with alkali hydroxide to generate the expansive alkali silica reaction products. Increasing the particle size and temperature increases the alkali silica reactivity of RHA. The mechanism for the successive pozzolanic and alkali silica reactions of RHA is theorized. Additionally, a new simple mix design method is proposed for SCHPC containing various supplementary cementitious materials, i.e. RHA, SF, fly ash and limestone powder.

ER - TY - THES A1 - Jia, Yue T1 - Methods based on B-splines for model representation, numerical analysis and image registration N2 - The thesis consists of inter-connected parts for modeling and analysis using newly developed isogeometric methods. The main parts are reproducing kernel triangular B-splines, extended isogeometric analysis for solving weakly discontinuous problems, collocation methods using superconvergent points, and B-spline basis in image registration applications. Each topic is oriented towards application of isogeometric analysis basis functions to ease the process of integrating the modeling and analysis phases of simulation. First, we develop reproducing a kernel triangular B-spline-based FEM for solving PDEs. We review the triangular B-splines and their properties. By definition, the triangular basis function is very flexible in modeling complicated domains. However, instability results when it is applied for analysis. We modify the triangular B-spline by a reproducing kernel technique, calculating a correction term for the triangular kernel function from the chosen surrounding basis. The improved triangular basis is capable to obtain the results with higher accuracy and almost optimal convergence rates. Second, we propose an extended isogeometric analysis for dealing with weakly discontinuous problems such as material interfaces. The original IGA is combined with XFEM-like enrichments which are continuous functions themselves but with discontinuous derivatives. Consequently, the resulting solution space can approximate solutions with weak discontinuities. The method is also applied to curved material interfaces, where the inverse mapping and the curved triangular elements are considered. Third, we develop an IGA collocation method using superconvergent points. The collocation methods are efficient because no numerical integration is needed. In particular when higher polynomial basis applied, the method has a lower computational cost than Galerkin methods. However, the positions of the collocation points are crucial for the accuracy of the method, as they affect the convergent rate significantly. The proposed IGA collocation method uses superconvergent points instead of the traditional Greville abscissae points. The numerical results show the proposed method can have better accuracy and optimal convergence rates, while the traditional IGA collocation has optimal convergence only for even polynomial degrees. Lastly, we propose a novel dynamic multilevel technique for handling image registration. It is application of the B-spline functions in image processing. The procedure considered aims to align a target image from a reference image by a spatial transformation. The method starts with an energy function which is the same as a FEM-based image registration. However, we simplify the solving procedure, working on the energy function directly. We dynamically solve for control points which are coefficients of B-spline basis functions. The new approach is more simple and fast. Moreover, it is also enhanced by a multilevel technique in order to prevent instabilities. The numerical testing consists of two artificial images, four real bio-medical MRI brain and CT heart images, and they show our registration method is accurate, fast and efficient, especially for large deformation problems.

In the last decade, security issues such as the PS3 jailbreak demonstrate that common security notions are rather restrictive, and it seems that they do not model the real world adequately. As a result, in the first part of this work, we introduce a less restrictive security model that is closer to reality. In this model it turned out that existing (on-line) authenticated encryption schemes cannot longer beconsidered secure, i.e. they can guarantee neither data privacy nor data integrity. Therefore, we present two novel authenticated encryption scheme, namely COFFE and McOE, which are not only secure in the standard model but also reasonably secure in our generalized security model, i.e. both preserve full data inegrity. In addition, McOE preserves a resonable level of data privacy. The second part of this thesis starts with proposing the hash function Twister-Pi, a revised version of the accepted SHA-3 candidate Twister. We not only fixed all known security issues of Twister, but also increased the overall soundness of our hash-function design. Furthermore, we present some fundamental groundwork in the area of password-hashing schemes. This research was mainly inspired by the medial omnipresence of password-leakage incidences. We show that the password-hashing scheme scrypt is vulnerable against cache-timing attacks due to the existence of a password-dependent memory-access pattern. Finally, we introduce Catena the first password-hashing scheme that is both memory-consuming and resistant against cache-timing attacks.

The research should be understood as an experiment to a systematic presentation of the symbolic visual world in Xinjiang and therefore in a broader sense as an experiment to preserve the endangered Xiyu-Cultural Heritage. Due to the profound change in China and the Go-West-Strategy of China’s economic programme an efficient way must be found to bring modernization and tradition in harmony. This study describes, analyses and evaluates exemplarily, how signs and symbols of knowledge and culture have been mixed between eastern and western cultures along the Silk Road in Xinjiang. It displays how they have been transferred and how far the Xiyu-Culture reflects, that Xinjiang was a meeting point of eastern and western cultures. In the process of my research three main questions arose: Firstly, what can the experience model of the ancient Silk Road contribute to the understanding of cultural development in today’s information age? Secondly, what does cultural diversity mean for communication in Xinjiang? Is there an increase of media technology in the field of visual communication because of international influences? Thirdly, how can Xinjiang benefit from the opportunities given by the Go-West-Strategy of China’s economic programme in an increasingly globalized world and find a balance between culture and economic prosperity? Therefore, this study uses a method that integrates a cultural-anthropological perspective. Characteristics of the traditional visual Xiyu-Signs, their significance for the ethnic groups in Xinjiang and cultural exchanges between Europe and Asia are discussed based on a field work, and the particular influence of trade and transport routes is presented. The visual signs of the Xiyu-Culture are shown from the time before the Islamization to today’s Islamic period. The research shows that the signs are not place-bound cultural phenomena or local tradition; they are rather influenced by regional, national and international cultures consciously or unconsciously. They are a result of cultural communication. Finally the signs of Xiyu-Culture of Xinjiang are thoroughly researched with the Go-West-Strategy of the Chinese government. Economic development brings to Xinjiang not only modernization and prosperity, but also a cultural and ecological imbalance. Mankind formed everything into structure, what he perceives around him, with signs. The Xiyu-Signs create a visual structure. The Xiyu-Culture still has influence on the lifestyle of the ethnic groups in Xinjiang. Today, the confrontation between the traditional Xiyu-Culture and economic development has led to a serious conflict in Xinjiang. This study is a critical interpretation of the current situation of Xiyu-Culture and the Chinese economic program in Xinjiang. It also contributes to the analysis of the hitherto insufficiently recognized interactions between history, culture, politics and economics of cultural globalization in Xinjiang. N2 - Kurzfassung Die vorliegende Studie untersucht die traditionellen Xiyü-Zeichen im Visuellen verschiedener Volksgruppen am Beispiel Xinjiangs im Nordwesten Chinas, wo einst die alte Seidenstraße entlangführte. Die Untersuchung versteht sich als ein Versuch der systematischen Darstellung der symbolischen Bildwelt in Xinjiang und damit im weiteren Sinne auch als ein Versuch, das Xiyü-Kulturerbe zu bewahren, das angesichts des tiefgreifenden Wandels in China und der Go-West-Strategie des chinesischen Wirtschaftsprogramms, welches sich auf die weiten Westgebiete Chinas bezieht, in Gefahr geraten ist. Es muss ein Weg gefunden werden, Modernisierung und Tradition in Einklang zu bringen. Diese Studie beschreibt, analysiert und bewertet exemplarisch, wie sich Zeichen und Symbole des Wissens und der Kultur entlang der Seidenstraße in Xinjiang zwischen den östlichen und westlichen Kulturen vermischt haben, wie sie übertragen wurden und inwieweit die Xiyü-Kultur reflektiert, dass Xinjiang ein Treffpunkt zwischen östlichen und westlichen Einflüssen war. In der Annährung an dieses Forschungsziel werden drei Hauptfragen zusammengefasst: Erstens, was kann das Erfahrungsmodell der alten Seidenstraße zum Verständnis der kulturellen Entwicklung im heutigen Informationszeitalter beitragen? Zweitens, was bedeutet Vielfalt für die kulturelle Kommunikation in Xinjiang? Steigen die Medienereignisse der visuellen Kommunikation und die internationalen Einflüsse an? Drittens, wie kann Xinjiang die Chancen der Go-West-Strategie des chinesischen Wirtschaftsprogramms in einer zunehmend globalisierten Welt nutzen und in der zukünftigen weltwirtschaftlichen Entwicklung wieder Vitalität zeigen? Um sich auf diese Weise den Antworten zu nähern, verwendet diese Studie einen Ansatz, der eine kulturanthropologische Perspektive integriert. Auf Grundlage einer Feldstudie werden Eigenschaften der traditionellen visuellen Xiyü-Zeichen, ihre Bedeutung für die ethnischen Volksgruppen Xinjiangs und den kulturellen Austausch zwischen Europa und Asien diskutiert und der besondere Einfluss von Handel und Verkehrswegen aufgezeigt. Die visuellen Zeichenformen der Xiyü-Kultur wurden von der Zeit vor der Islamisierung bis hin zur heutigen islamischen Zeit dargestellt. Die Forschung zeigt, dass die Zeichen kein ortsgebundenes Kulturphänomen oder eine lokale Tradition sind, vielmehr werden sie von regionalen, nationalen und internationalen Kulturkreisen bewusst oder unbewusst beeinflusst. Sie sind ein Ergebnis kultureller Kommunikation. Schließlich setzt sich die Studie mit den Zeichen der Xiyü-Kultur Xinjiangs in Relation mit der Go-West-Strategie der chinesischen Regierung auseinander. Die wirtschaftliche Entwicklung bringt für Xinjiang nicht nur Modernisierung und Wohlstand, sondern auch ein kulturelles und ökologisches Ungleichgewicht. Der Mensch strukturiert alles, was er in seiner Umgebung wahrnimmt, mit Zeichen. Die Xiyü-Zeichen schaffen eine visuelle Strukturierung. Die Xiyü-Kultur hat nach wie vor Einfluss auf die Lebensweise der ethnischen Gruppen in Xinjiang. Heute hat die Konfrontation zwischen der traditionellen Xiyü-Kultur und der wirtschaftlichen Entwicklung zu einem ernsthaften Konflikt in Xinjiang geführt. Diese Studie versteht sich als eine kritische Interpretation der aktuellen Situation der Xiyü-Kultur bzw. des chinesischen Wirtschaftsprogramms in Xinjiang. Sie will darüber hinaus einen Beitrag leisten zur Analyse der bislang nur unzureichend erfassten Wechselwirkungen zwischen Geschichte, Kultur, Politik und Wirtschaft in der kulturellen Globalisierung in Xinjiang.

Resting upon the basis of traditional continent philosophy, this social space theory has adopted the structuration methods, at the same time trying to build certain combination between theoretical frame work establishment and empirical observations. Therefore, the socio-spatial transition study is neither a macro theory of traditional structuralism nor a typology of urban planning theory, or a positivism social geography, but an operative theory on practical purpose. Firstly, what’s distinct from the traditional structuralism is that this study examines the endless transiting structural relations, not macroscopic narrations of absolute definition and structure. In fact, any city and space are always co-existed in their structurational transiting relationship, thus research in transition has become the main body of this study. And case study is a must for research in transition, as part of efforts to apply the structuration concept into practice reason. Secondly, this study first establishes the fundamental structuration concept of socio-spatial transition, which, as an operative tool, is applied to conduct transition analysis on specific case about the City of Beijing. Therefore, as a social space theory, referring to as science, remains criticism of traditional continent philosophy. However, this criticism did not working on the level of ideology or conceptions, but on transiting under structural relations, keeping it from incompetent ideology criticism of continental critical theory. Unfortunately contemporary urban and space development have now gone extremely unbalanced under a background of globalization; yet traditional macro theories are incapable of either producing significant impact on practice or helping people identify practical problems. While facing general issues, particularly the Chinese urban issue category established on a meta-structured city mode, the micro-case study has plunged into dilemma for unknowing either to ask questions or to answer questions. Therefore, this study is set to identify dilemma and find direction for future relevant research. In this dissertation, Beijing is used as a model, and structuration methods as tools. It has extensively analyzed the social-spatial transition of the city space of Beijing, acquiring brand-new knowledge of its urban space development. It is helpful to an in-depth understanding of the city space development not only in Beijing, but also in many other cities that were influenced by the capital model of Beijing. Since the start of reform and opening-up, China has created a unique development mode of the new-styled metropolitan and urbanization in history. This research is expected to analyze or decode what China’s urban development in between communal space and associative space.

In approaching this phenomenon, the research highlights how people interact with their institutional environments. This is also, perhaps centrally, an investigation into the possibility to engage an individual perspective to understand the transformation in urban experience, which is orienting society to new uses and forms of exclusion. Following the perspective deployed by the so-called “sociology of individuals” in French sociology or “reengagement of agency” in the Anglo-Saxon world; I claim that individuals as well as collectives are gaining increasing power to question and re-organize institutions. This re-organization, in the case of socio-urban institutions, is no guarantee for major levels in integration, cohesion, and equality. Unfortunately, social institutions are becoming hard in its exclusionary capabilities under people intervention during the last four decades. I believe that urban sociology is a field of struggle between different perspectives competing to “make sense” of social phenomena in cities. The orientation supported in this research is just one on many and it follows the roots of people and their life experiences within cities and how they influence the processes that shape the city. The last formulation is possibly not the clearest, because as we all know, references to “inhabitants” are presented in every variant of urban sociology. Nevertheless, there are not many variants focusing on peoples’ capability to influence institutional environments and by this way affecting the urban condition in which they find themselves. The particular institution selected for this study is the “School”. This thesis is organized around two parts: part one includes the conceptual framework, methodological approach, and historical contextualization; part two describes three case studies produced to analyse the forms of and the relations between individuals and school institution. Part one starts from a premise: within the context of declining welfare State in the case of industrialized countries, an important part of urban studies focuses on economic and spatial restructuration. Confronted with the same situation, a part of social sciences shifts to the individuals’ agency and social uncertainty. This research is embedded in the last theoretical description presented above, thus, because it tries to observe urban processes from the perspective of the individual and outside of developed economies. In this sense, Latin America represents a fundamental reference because urban conditions are historically marked by weak institutional arrangements to integrating people and large levels of marginality and exclusion among population. In this scenario individuals’ practices around inclusion-exclusion have an essential meaning in everyday life. Part two offers three study cases in which the relation between individuals and school institutions has been analyzed for the Metropolitan area of Santiago de Chile (MAS). Using different methodological resources an exhaustive account on three levels is presented: i) geo-referencing State intervention in public policies connected with neighborhood and schools to understand the form and extent of socio-urban exclusion in MAS, ii) narrative biographies applied to parents with children attending primary school, in order to reconstruct the familiar process of school selection and describing its impacts on the stabilization of school as an exclusionary device, and iii) autoethnography to describe in detail the temporal dimension involved in stabilizing actions which reinforces social mechanisms of urban integration-exclusion during the last three decades in Chile. A key argument advanced by this research proposes that: the way in which the idea of integration is enacted by people in their biographical careers imprints changes on the institutional orientation and by this way, contributes to the reorganization urban life. The high level of social exclusion in Santiago de Chile is not accountable without considering transformation in all socio-urban institutions, especially the school. No family considers social integration with people from a low social, economical or cultural background as relevant orientation for school selection. This particularity of the Chilean social reality is not derivable from any big capitalistic or modernization processes impacting our cities. Within the light of the thesis findings, I conclude that socio-urban institutions logics must be reassessment under the influences of people actions and representations. I also propose a consideration to major complementarities between urban studies and urban-institutions analysis. The school institutions is not just a sectorial field reserved to the researcher in education, on the contrary, it represent a key entrance to address people’s experience in their institutional urban environments. The re-emergence of social and urban movements in 2010, under the “Arab Spring” or the “Chilean Student Movements”, is not only a demonstration in the public space as result of major global trends. These situations are in essence, for this research, individuals gathering together and calling for recognition and autonomy inside institutional environment that tends to reject them. Similar situation was the focus of the Latin American urban sociology research, within the focus on grassroots and urban social movements at the end of the 1960s and beginning of the 1970s. In both cases, socio-urban institutions, unaware of recognition requirements claimed by inhabitants, are not beyond individual or collective reach. My main concern is to show that socio-urban institutions are constantly re-shaped as a result of individual action, what makes the difference, is the spirit that we all, socially, imprint on the logics of our socio-urban institutions, moving them to inclusion or exclusion.
