A variety of approaches have been proposed to extend classical fixed income portfolio immunization theory to cases where shifts in the term structure are not parallel. Following Reitano (1991a, 1991b, 1992, 1996) and Poitras (2007), this paper uses partial durations and convexities to specify benchmark partial immunization bounds for non-parallel term structure shifts. Theoretical results are obtained by exploiting properties of the multivariate Taylor series expansion of the spot interest rate pricing function. It is demonstrated that the partial immunization bounds can be effectively manipulated by adequate selection of the securities being used to immunize the portfolio. The inclusion of time values permits the results obtained to be related to previous studies by Christensen and Sorensen (1994), Chance and Jordan (1996), Barber and Copper (1997) and Poitras (2005, Ch. 5) on the time value-convexity tradeoff.

The data movement between the processing and storage units has been one of the most critical issues in modern computer systems. The emerging Resistive Random Access Memory (RRAM) technology has drawn tremendous attention due to its non-volatile ability and the potential in computation application. These properties make them a perfect choice for application in modern computing systems. In this paper, an 8-bit radix-4 non-volatile parallel multiplier is proposed, with improved computational capabilities. The corresponding booth encoding scheme, read-out circuit, simplified Wallace tree, and Manchester carry chain are presented, which help to short the delay of the proposed multiplier. While the presence of RRAM save computational time and overall power as multiplicand is stored beforehand. The area of the proposed non-volatile multiplier is reduced with improved computing speed. The proposed multiplier has an area of 785.2 μm2 with Generic Processing Design Kit 45 nm process. The simulation results show that the proposed multiplier structure has a low computing power at 161.19 μW and a short delay of 0.83 ns with 1.2 V supply voltage. Comparative analyses are performed to demonstrate the effectiveness of the proposed multiplier design. Compared with conventional booth multipliers, the proposed multiplier structure reduces the energy and delay by more than 70% and 19%, respectively.

Unlike the traditional Gough-Stewart platform with axial symmetrical structure, a parallel manipulator consists of non axial symmetrical structure has non axial symmetrical characteristic in the whole reachable workspace. This paper presents the joint capability evaluation of a parallel manipulator with non axial symmetrical characteristics. A series of velocity, torque and power indices are presented. The torque indices combining the acceleration, velocity, and gravity components of the dynamic model are used to evaluate the respective joint torque capability. The power indices corresponding to the torque indices are also adopted to evaluate the respective joint power capability. The joint capability evaluation of the parallel manipulator is carried out through computational analysis and simulation with the velocity, torque and power indices. It is shown that the respective actuating joint capabilities of the parallel manipulator are not uniform due to the non axial symmetrical structure. Thus the performance evaluation of this type of parallel manipulator must be performed by analyzing the respective joint capability. By means of these indices with obvious physical meanings, it is possible to control the respective joint capability of the parallel manipulator. The indices are general and can be used for the other types of parallel manipulators.

Parallel structure robots have been receiving growing attention from both academia and industry in recent years. This is due to their advantages over serial structure robots, such as high stiffness, high motion accuracy and a high load-structure ratio. Control of parallel robots, however, produces difficulties to control engineers due to the modelling errors arising from the highly non-linear and complex structures. This paper proposes a dual-model-based structure for error attenuation in the trajectory-tracking control of a parallel robot manipulator. In this design, a conventional model-based control algorithm employing an estimated robot dynamic model is first implemented in the inner loop of the control structure. Then, in order to reduce the unwanted effects caused by modelling erros, another model-based structure, developed based on the concept of the internal model control, is appended in the outer loop of the control structure as a compensator. A combination of these two model-based components results in a novel dual-model-based structure for parallel robot control. Sensitivity analyses show that the effects due to modelling errors and external disturbances can be significantly reduced by applying this new control structure without relying on a high-gain control solution. The effectiveness of this control design is successfully demonstrated by numerical studies on a planar parallel robot with 2 degrees of freedom.

Linear stability of the non-parallel Batchelor vortex is studied using global modes. This family of swirling wakes and jets has been extensively studied under the parallel-flow approximation, and in this paper we extend to more realistic non-parallel base flows. Our base flow is obtained as an exact steady solution of the Navier–Stokes equations by direct numerical simulation (with imposed axisymmetry to damp all instabilities). Global stability modes are computed by numerical simulation of the linearized equations, using the implicitly restarted Arnoldi method, and we discuss fully the numerical and convergence issues encountered. Emphasis is placed on exploring the general structure of the global spectrum, and in particular the correspondence between global modes and local absolute modes which is anticipated by weakly non-parallel asymptotic theory. We believe that our computed global modes for a weakly non-parallel vortex are the first to display this correspondence with local absolute modes. Superpositions of global modes are also studied, allowing an investigation of the amplifier dynamics of this unstable flow. For an illustrative case we find global non-modal transient growth via a convective mechanism. Generally amplifier dynamics, via convective growth, are prevalent over short time intervals, and resonator dynamics, via global mode growth, become prevalent at later times.

Quadtrees and octrees are hierarchical data structures for efficiently storing image data. Quadtrees represent two dimensional images, while octrees are a generalization to three dimensions. The linear form of each is an abstraction of the tree structure to reduce storage requirements. We have developed a parallel algorithm to efficiently create a linear octree from quadtree slices of an object without the use of an intermediate data structure. We also propose the d-slice, which is a generalization of an octree, and which efficiently represents non-cubic volumes.

Texto completoResumen
This work details the development of a computational tool that can accurately model strongly-coupled fluid-structure-interaction (FSI) problems, with a particular focus on thin-walled structures undergoing large, geometrically non-linear deformations, which has a major interest in, amongst others, the aerospace and biomedical industries. The first part of this work investigates improving the efficiency with which a stable and robust in-house code, Elemental, models thin structures undergoing dynamic fluid-induced bending deformations. Variations of the existing finite volume formulation as well as linear and higher-order finite element formulations are implemented. The governing equations for the solid domain are formulated in a total Lagrangian or undeformed conguration and large geometrically non-linear deformations are accounted for. The set of equations is solved via a single-step Jacobi iterative scheme which is implemented such as to ensure a matrix-free and robust solution. Second-order accurate temporal discretisation is achieved via dual-timestepping, with both consistent and lumped mass matrices and with a Jacobi pseudo-time iteration method employed for solution purposes. The matrix-free approach makes the scheme particularly well-suited for distributed memory parallel hardware architectures. Three key outcomes, not well documented in literature, are highlighted: the issue of shear locking or sensitivity to element aspect ratio, which is a common problem with the linear Q4 finite element formulation when subjected to bending, is evaluated on the finite volume formulations; a rigorous comparison of finite element vs. finite volume methods on geometrically non-linear structures is done; a higher-order finite volume solid mechanics procedure is developed and evaluated. The second part of this work is concerned with fluid-structure interaction (FSI) modelling. It considers the implementation and coupling of a higher order finite element structural solver with the existing finite volume fluid-flow solver in Elemental. To the author’s knowledge, this is the first instance in which a strongly-coupled hybrid finite element–finite volume FSI formulation is developed. The coupling between the fluid and structural components with non-matching nodes is rigorously assessed. A new partitioned fluid-solid interface coupling methodology is also developed, which ensures stable partitioned solution for strongly-coupled problems without any additional computational overhead. The solver is parallelised for distributed memory parallel hardware architectures. The developed technology is successfully validated through rigorous temporal and mesh independent studies of representative two-dimensional strongly-coupled large-displacement FSI test problems for which analytical or benchmark solutions exist.Dissertation (MEng)--University of Pretoria, 2012.

In the past years the so-called body-centered cubic grid (bcc) has been examined and proved to be superior over Cartesian lattices for certain applications. Our work deals with parallel thinning on these bcc grids. We introduce conditions which are sufficient for retaining topology and suggest additional conditions to influence the shape of the resulting skeleton. We further developed an algorithm to extract curve skeletons out of 3d objects in parallel which we also present here.
We show in our results that the developed thinning approach on bcc grids is extremely efficient.

O estudo do comportamento mecânico do complexo sistema advindo da interação entre solo/subestrutura/superestrutura é o tema do trabalho. Neste contexto, a representação do maciço é feita usando-se o método dos elementos de contorno (MEC) em abordagem 3D, de maneira que se possa simular o maciço com características mecânicas não-homogêneas, além de se considerar uma camada de apoio indeslocável a distâncias prescritas a priori e condição de aderência perfeita. A subestrutura também é representada via MEC tridimensional, a qual está imersa dentro deste meio heterogêneo. A infra e a superestrutura são modeladas empregando o método dos elementos finitos (MEF), com o uso de elementos estruturais reticulares e elementos laminares. São apresentados alguns exemplos em que se valida a formulação e outros que demonstram a potencialidade e a necessidade de se empregar a formulação para a melhor análise do complexo fenômeno em estudo. Por fim, demonstra-se a obrigatoriedade de se otimizar a formulação, empregando-se duas grandes ferramentas numéricas: o paralelismo e o emprego de um adequado método de resolução de sistemas esparsos.The analysis of the soil-structure system interaction is a vast field of interest in the area of civil engineering. A realistic representation of its behaviour. Thus, in the present research, the soil is considered a non-homogeneous continuum supported by a rigid and adhesive interface and modelled by boundary element method via Kelvin solution in 3D space. The foundation is also modelled by this above-mentioned modelling technique. The raft foundation and the superstructure are represented by finite shell and 3D frame elements. In order to estimate the accuracy and the potentiality of the proposed numerical formulation, some examples are validated when compared to similar approaches, and others simulations are presented to stress the necessity of coupling the non-homogeneous soil-foundation-radier-superstructure system as a whole. Finally, to acquire numerical time efficiency, it is shown that it is imperative to apply parallel processing and sparse techniques for the solution of the final system.

Texto completoResumen
The objective of this research is to develop an efficient and accurate methodology to resolve flow non-linearity of fluid-structural interaction. To achieve this purpose, a numerical strategy to apply the detached-eddy simulation (DES) with a fully coupled fluid-structural interaction model is established for the first time. The following novel numerical algorithms are also created: a general sub-domain boundary mapping procedure for parallel computation to reduce wall clock simulation time, an efficient and low diffusion E-CUSP (LDE) scheme used as a Riemann solver to resolve discontinuities with minimal numerical dissipation, and an implicit high order accuracy weighted essentially non-oscillatory (WENO) scheme to capture shock waves. The Detached-Eddy Simulation is based on the model proposed by Spalart in 1997. Near solid walls within wall boundary layers, the Reynolds averaged Navier-Stokes (RANS) equations are solved. Outside of the wall boundary layers, the 3D filtered compressible Navier-Stokes equations are solved based on large eddy simulation(LES). The Spalart-Allmaras one equation turbulence model is solved to provide the Reynolds stresses in the RANS region and the subgrid scale stresses in the LES region. An improved 5th order finite differencing weighted essentially non-oscillatory (WENO) scheme with an optimized epsilon value is employed for the inviscid fluxes. The new LDE scheme used with the WENO scheme is able to capture crisp shock profiles and exact contact surfaces. A set of fully conservative 4th order finite central differencing schemes are used for the viscous terms. The 3D Navier-Stokes equations are discretized based on a conservative finite differencing scheme, which is implemented by shifting the solution points half grid interval in each direction on the computational domain. The solution points are hence located in the center of the grid cells in the computational domain (not physical domain). This makes it possible to use the same code structure as a 2nd order finite volume method. A finite differencing high order WENO scheme is used since a finite differencing WENO scheme is much more efficient than a finite volume WENO scheme. The unfactored line Gauss-Seidel relaxation iteration is employed for time marching. For the time accurate unsteady simulation, the temporal terms are discretized using the 2nd order accuracy backward differencing. A pseudo temporal term is introduced for the unsteady calculation following Jameson's method. Within each physical time step, the solution is iterated until converged based on pseudo time step. A general sub-domain boundary mapping procedure is developed for arbitrary topology multi-block structured grids with grid points matched on sub-domain boundaries. The interface of two adjacent blocks is uniquely defined according to each local mesh index system (MIS) which is specified independently. A pack/unpack procedure based on the definition of the interface is developed to exchange the data in a 1D array to minimize data communication. A secure send/receive procedure is employed to remove the possibility of blocked communication and achieve optimum parallel computation efficiency. Two terms, "Order" and "Orientation", are introduced as the logics defining the relationship of adjacent blocks. The domain partitioning treatment of the implicit matrices is to simply discard the corner matrices so that the implicit Gauss-Seidel iteration can be implemented within each subdomain. This general sub-domain boundary mapping procedure is demonstrated to have high scalability. Extensive numerical experiments are conducted to test the performance of the numerical algorithms. The LDE scheme is compared with the Roe scheme for their behavior with RANS simulation. Both the LDE and the Roe scheme can use high CFL numbers and achieve high convergence rates for the algebraic Baldwin-Lomax turbulence model. For the Spalart-Allmaras one equation turbulence model, the extra equation changes the Jacobian of the Roe scheme and weakens the diagonal dominance. It reduces the maximum CFL number permitted by the Roe scheme and hence decreases the convergence rate. The LDE scheme is only slightly affected by the extra equation and maintains high CFL number and convergence rate. The high stability and convergence rate using the Spalart-Allmaras one equation turbulence model is important since the DES uses the same transport equation for the turbulence stresses closure. The RANS simulation with the Spalart-Allmaras one equation turbulence model is the foundation for DES and is hence validated with other transonic flows including a 2D subsonic flat plate turbulent boundary layer, 2D transonic inlet-diffuser, 2D RAE2822 airfoil, 3D ONERA M6 wing, and a 3D transonic duct with shock boundary layer interaction. The predicted results agree very well with the experiments. The RANS code is then further used to study the slot size effect of a co-flow jet (CFJ) airfoil. The DES solver with fully coupled fluid-structural interaction methodology is validated with vortex induced vibration of a cylinder and a transonic forced pitching airfoil. For the cylinder, the laminar Navier-Stokes equations are solved due to the low Reynolds number. The 3D effects are observed in both stationary and oscillating cylinder simulation because of the flow separations behind the cylinder. For the transonic forced pitching airfoil DES computation, there is no flow separation in the flow field. The DES results agree well with the RANS results. These two cases indicate that the DES is more effective on predicting flow separation. The DES code is used to simulate the limited cycle oscillation of NLR7301 airfoil. For the cases computed in this research, the predicted LCO frequency, amplitudes, averaged lift and moment, all agree excellently with the experiment. The solutions appear to have bifurcation and are dependent on the initial perturbation. The developed methodology is able to capture the LCO with very small amplitudes measured in the experiment. This is attributed to the high order low diffusion schemes, fully coupled FSI model, and the turbulence model used. This research appears to be the first time that a numerical simulation of LCO matches the experiment. The DES code is also used to simulate the CFJ airfoil jet mixing at high angle of attack. In conclusion, the numerical strategy of the high order DES with fully coupled FSI model and parallel computing developed in this research is demonstrated to have high accuracy, robustness, and efficiency. Future work to further maturate the methodology is suggested.

L'objectif principal est de faire premiers pas vers la conception topologique de structures hétérogènes à comportement non-linéaires. Le deuxième objectif est d’optimiser simultanément la topologie de la structure et du matériau. Il requiert la combinaison des méthodes de conception optimale et des approches de modélisation multi-échelle. En raison des lourdes exigences de calcul, nous avons introduit des techniques de réduction de modèle et de calcul parallèle. Nous avons développé tout d’abord un cadre de conception multi-échelle constitué de l’optimisation topologique et la modélisation multi-échelle. Ce cadre fournit un outil automatique pour des structures dont le modèle de matériau sous-jacent est directement régi par la géométrie de la microstructure réaliste et des lois de comportement microscopiques. Nous avons ensuite étendu le cadre en introduisant des variables supplémentaires à l’échelle microscopique pour effectuer la conception simultanée de la structure et de la microstructure. En ce qui concerne les exigences de calcul et de stockage de données en raison de multiples réalisations de calcul multi-échelle sur les configurations similaires, nous avons introduit: les approches de réduction de modèle. Nous avons développé un substitut d'apprentissage adaptatif pour le cas de l’élasticité non-linéaire. Pour viscoplasticité, nous avons collaboré avec le Professeur Felix Fritzen de l’Université de Stuttgart en utilisant son modèle de réduction avec la programmation parallèle sur GPU. Nous avons également adopté une autre approche basée sur le potentiel de réduction issue de la littérature pour améliorer l’efficacité de la conception simultanéeHigh-performance heterogeneous materials have been increasingly used nowadays for their advantageous overall characteristics resulting in superior structural mechanical performance. The pronounced heterogeneities of materials have significant impact on the structural behavior that one needs to account for both material microscopic heterogeneities and constituent behaviors to achieve reliable structural designs. Meanwhile, the fast progress of material science and the latest development of 3D printing techniques make it possible to generate more innovative, lightweight, and structurally efficient designs through controlling the composition and the microstructure of material at the microscopic scale. In this thesis, we have made first attempts towards topology optimization design of multiscale nonlinear structures, including design of highly heterogeneous structures, material microstructural design, and simultaneous design of structure and materials. We have primarily developed a multiscale design framework, constituted of two key ingredients : multiscale modeling for structural performance simulation and topology optimization forstructural design. With regard to the first ingredient, we employ the first-order computational homogenization method FE2 to bridge structural and material scales. With regard to the second ingredient, we apply the method Bi-directional Evolutionary Structural Optimization (BESO) to perform topology optimization. In contrast to the conventional nonlinear design of homogeneous structures, this design framework provides an automatic design tool for nonlinear highly heterogeneous structures of which the underlying material model is governed directly by the realistic microstructural geometry and the microscopic constitutive laws. Note that the FE2 method is extremely expensive in terms of computing time and storage requirement. The dilemma of heavy computational burden is even more pronounced when it comes to topology optimization : not only is it required to solve the time-consuming multiscale problem once, but for many different realizations of the structural topology. Meanwhile we note that the optimization process requires multiple design loops involving similar or even repeated computations at the microscopic scale. For these reasons, we introduce to the design framework a third ingredient : reduced-order modeling (ROM). We develop an adaptive surrogate model using snapshot Proper Orthogonal Decomposition (POD) and Diffuse Approximation to substitute the microscopic solutions. The surrogate model is initially built by the first design iteration and updated adaptively in the subsequent design iterations. This surrogate model has shown promising performance in terms of reducing computing cost and modeling accuracy when applied to the design framework for nonlinear elastic cases. As for more severe material nonlinearity, we employ directly an established method potential based Reduced Basis Model Order Reduction (pRBMOR). The key idea of pRBMOR is to approximate the internal variables of the dissipative material by a precomputed reduced basis computed from snapshot POD. To drastically accelerate the computing procedure, pRBMOR has been implemented by parallelization on modern Graphics Processing Units (GPUs). The implementation of pRBMOR with GPU acceleration enables us to realize the design of multiscale elastoviscoplastic structures using the previously developed design framework inrealistic computing time and with affordable memory requirement. We have so far assumed a fixed material microstructure at the microscopic scale. The remaining part of the thesis is dedicated to simultaneous design of both macroscopic structure and microscopic materials. By the previously established multiscale design framework, we have topology variables and volume constraints defined at both scales

Texto completoResumen
This thesis deals with the correlative markers d’une part… d’autre part, d’un côté… de l’autre and non seulement… mais in French and their Swedish counterparts dels… dels, å ena sidan… å andra sidan and inte bara… utan. These markers are composed of two separate parts generally occurring together, and announce a serial of at least two textual units to be considered together. The analyses of the use of these three French and three Swedish markers are based upon two corpora of non-academic humanities texts. The first, principal corpus, is composed only of original French and Swedish texts. The second, complementary corpus, is composed of source texts in the two languages and their translations in the other language. By the combination of these two corpora, this study is comparative as well as contrastive. Through application of the Geneva model of discourse analysis and the Rhetorical Structure Theory, a semantic and functional approach to correlative markers and their text-structural role is adopted. The study shows similarities as well as differences between the six markers, both within each language and between the languages. D’une part… d’autre part and dels… dels principally mark a conjunctive relation, whereas d’un côté… de l’autre and å ena sidan… å andra sidan more often are used in a contrastive relation, even though they all can be used for both kinds of relations. Non seulement… mais and inte bara… utan mark a conjunctive relation, but can also indicate that the second argument is stronger than the first one. By the use of these two markers, the language users also present the first one as given and the second one as new information. In general, the French correlative markers appear to have a more argumentative function, whereas the text-structural function is demonstrated to be the most important in Swedish.

L'objectif de cette thèse était de proposer, puis de valider expérimentalement, un ensemble de méthodes algorithmiques permettant le remaillage parallèle de maillages distribués, en s'appuyant sur une méthode séquentielle de remaillage préexistante. Cet objectif a été atteint par étapes : définition de structures de données et de schémas de communication adaptés aux maillages distribués, permettant le déplacement à moindre coût des interfaces entre sous-domaines sur les processeurs d'une architecture à mémoire distribuée ; utilisation d'algorithmes de répartition dynamique de la charge adaptés aux techniques parallèles de remaillage ; conception d'algorithmes parallèles permettant de scinder le problème global de remaillage parallèle en plusieurs sous-tâches séquentielles, susceptibles de s'exécuter concurremment sur les processeurs de la machine parallèle. Ces contributions ont été mises en oeuvre au sein de la bibliothèque parallèle PaMPA, en s'appuyant sur les briques logicielles MMG3D (remaillage séquentiel de maillages tétraédriques) et PT-Scotch (repartitionnement parallèle de graphes). La bibliothèque PaMPA offre ainsi les fonctionnalités suivantes : communication transparente entre processeurs voisins des valeurs portées par les noeuds, les éléments, etc. ;remaillage, selon des critères fournis par l'utilisateur, de portions du maillage distribué, en offrant une qualité constante, que les éléments à remailler soient portés par un unique processeur ou bien répartis sur plusieurs d'entre eux ; répartition et redistribution de la charge des maillages pour préserver l'efficacité des simulations après remaillage.

É notório que o emprego de unidades de processamento gráfico (GPU) pode acelerar significativamente métodos numéricos de aplicações científicas. Para suportar essa nova tecnologia, é necessário que programas sejam readaptados, exigindo flexibilidade do código. Nesse trabalho, é apresentada a arquitetura de um programa de elementos finitos (MEF) para a análise de estruturas, com suporte ao processamento em GPU. A orientação a objetos é usada para guiar o desenvolvimento e modelar o código em uma estrutura flexível. A escalabilidade do programa é dada pela extensão de suas funcionalidades através de componentes carregados em tempo de execução. Para ilustrar a robustez do código, o software é aplicado para o estudo de dinâmica estrutural, considerando aspectos complexos de não linearidade de material (plasticidade) e geometria (grandes deslocamentos). A acurácia do código é verificada através da comparação com problemas conhecidos da literatura e com as soluções MEF comerciais (ABAQUS). As comparações mostraram uma boa concordância nos resultados. O speedup da GPU é analisado em relação aos tempos de CPU do próprio programa, sendo observado ganhos de desempenho de até 10 vezes.It has been recognized that the adoption of graphics processing units (GPU) can significantly boost numerical methods in scientific applications. In order to support such technology, it is necessary to readapt the program, which requires code flexibility. In this work, it is presented the architecture of a finite element (FEM) analysis program for structural analysis with GPU support. Object-oriented design is used to guide development and to build code into a flexible structure. Program scalability is achieved by extensibility of its features, provided by run-time loaded components. In order to demonstrate code robustness, the software is directed to the study of structural dynamics, considering complex non-linear aspects of material (plasticity) and geometry (large displacements). Code accuracy is checked by comparing with known literature problems and with commercial solver packages (ABAQUS). The comparison shows good agreement in the results. The GPU code speedup is analysed against timings of CPU program code, where it is observed performance gain up to 10 times.

Texto completoResumen
Mirrors and Vanities is a multi-modal collection which showcases the diversity of working in long and short storytelling forms. Featured in this thesis are fiction, nonfiction, graphic narrative, and screenplay. Using unconventional approaches to storytelling in order to achieve emotional resonance with the audience while maintaining high standards for craft, these stories and essays explore the costs inherent to the subtle nuances of interpersonal relationships. The fiction focuses on the complications of characters keeping secrets. A husband discovers the truth behind his wife's miscarriage. A girl visits her fiance in purgatory. A boy crosses a line and loses his best friend. Meanwhile, the nonfiction centers on self-discovery and gender roles associated with power struggles. A schizophrenic threatens to ruin my mother's wedding. I rediscover my relationship with my father through food writing. Sword-work teaches me to fail and succeed at making martial art. The title work of the thesis is a collaged story highlighting the tribulations of a physicist fixated on recovering his lost love by manipulating the multiverse. The multi-modal format implicates the nebulosity of physics theories and how different aspects of the narrative can be presented in various formats to best suit the nature of the storytelling. Through the interactions of characters in mundane and extraordinary circumstances, the works in this thesis examine the consequences of choice, the contrast between reality and expectation, coming of age, and the Truth of narrative.M.F.A.

Texto completoResumen
This book presents theoretical and empirical research on the syntax of events within the broader framework of generative grammar. A central theoretical concern is how conceptual meaning interacts with narrow syntactic computation in the derivation of the information of an event. A set of Integration Conditions are proposed. Building on the Conceptual-Intentional Interface Conditions proposed in Chomsky’s (1995, 2000, 2001) Minimalist Programme, the Integration Conditions require that the content of the predicate be licensed by theta-role information generated by narrow syntax. Another theoretical component concerns the functional structure of events, which is related to such issues as the parallel between the event and nominal domains, the mapping of a predicate onto an entity, as well as the grammatical foundation of verb classification. The theoretical framework is applied in three areas: (1) the syntax of resultatives in English and Chinese, which exhibits how a theory of the syntax of events can address the thematic relationship between core arguments and predicates; (2) variation of resultatives at cross-linguistic and diachronic levels, which shows how the universal functional structure of events can be compatible with, and even contribute to, the theory of parametric variation in the generative tradition; and (3) applicative constructions, which extend the analysis of core arguments to non-core arguments, and shed light on the typology of verb/satellite-framed languages (Talmy 1991, 2000) and the analyticity parameter proposed in Huang (2015).

Texto completoResumen
This chapter critically discusses another attempt to refute, without making any significant metaphysical or epistemic assumption, the classical ontological argument for perfect being theism. The attempt in question appeals to parallel parodies of the argument purporting to derive the existence (or non-existence) of various absurd entities, such as the ‘Lost Island’, ‘AntiGod’, and the ‘devil’. The chapter argues that the parowdy objection fails because it contains structural and dialectic flaws. It argues, moreover, that, once a parody is modified in such a way as to eliminate its flaws it is, ironically, no longer a parody—it is the ontological argument itself. Of course, one can hardly undermine the ontological argument by appealing to the ontological argument itself.

Texto completoResumen
Peculiar Attunements places the recent turn to affect into conversation with a parallel movement that took place in European music theory of the eighteenth century. During that time the affects—or the passions, as they were also called—formed a vital component of a mimetic model of the arts. Eighteenth-century critics held that artworks imitated or copied the natural world in order to produce copies of the affects in their beholders. But music caused a problem for these thinkers, since it wasn’t apparent that musical tones could imitate anything with any dependability (except, perhaps, for the rare thunderclap or birdcall). Struggling to articulate how it was that music managed to move its auditors without imitation, certain theorists developed a new affect theory crafted especially for music. These theorists postulated that it was music’s physical materiality as sound that vibrated the nerves of listeners and attuned them to the affects through sympathetic resonance. This was a theory of affective attunement that bypassed the entire structure of representation, offering a non-discursive, corporeal alternative. Inflecting our current intellectual moment through eighteenth-century music theory and aesthetics, this book offers a reassessment of affect theory’s common systems and processes. It offers a new way of thinking through affect dialectically, drawing attention to patterns and problems in affect theory that we have been given to repeating. Finally, taking a cue from eighteenth-century theory, it argues for renewed attention to the objects that generate affects in subjects.

Texto completoResumen
The discipline of linguistics in general, and the field of African linguistics in particular, appear to be facing a paradigm shift. There is a strong movement away from established methodologies and theoretical approaches, especially structural linguistics and generativism, and a broad move towards critical linguistics, sociolinguistics, and linguistic anthropology. These developments have encouraged a greater awareness and careful discussion of basic problems of data production in linguistics, as well as the role played by the ideologies of researchers. The volume invites a critical engagement with the history of the discipline, taking into account its deep entanglements with colonial knowledge production. Colonial concepts about language have helped to implement Northern ideas of what counts as knowledge and truth; they have established institutions and rituals of education, and have led to the lasting marginalization of African ways of speaking, codes, and multilingualisms. This volume engages critically with the colonial history of our discipline and argues that many of the colonial paradigms of knowledge production are still with us, shaping linguistic practices in the here-and-now as well as non-specialist talk about language and culture. The contributors explore how metalinguistic concepts and ways of creating linguistic knowledge are grounded in colonial practice, and exist parallel to, and sometimes in dialogue with other knowledges about language.

Texto completoResumen
Institutions matter for the advancement of human rights in global health. Given the dramatic development of human rights under international law and the parallel proliferation of global institutions for public health, there arises an imperative to understand the implementation of human rights through global health governance. This volume examines the evolving relationship between human rights, global governance, and public health, studying an expansive set of health challenges through a multi-sectoral array of global organizations. To analyze the structural determinants of rights-based governance, the organizations in this volume include those international bureaucracies that implement human rights in ways that influence public health in a globalizing world. Bringing together leading health and human rights scholars and practitioners from academia, non-governmental organizations, and the United Nations system, this volume explores: (1) the foundations of human rights as a normative framework for global health governance, (2) the mandate of the World Health Organization to pursue a human rights-based approach to health, (3) the role of inter-governmental organizations across a range of health-related human rights, (4) the influence of rights-based economic governance on public health, and (5) the focus on global health among institutions of human rights governance. Contributing chapters map the distinct human rights activities within a specific institution of global governance for health. Through the comparative institutional analysis in this volume, the contributing authors examine institutional efforts to operationalize human rights in organizational policies, programs, and practices and assess institutional factors that facilitate or inhibit human rights mainstreaming for global health advancement.

Texto completoResumen
Myocardium is an exquisitely structured and thoroughly dynamic living continuum. Within this multidifferentiated continuum, the subcellular and cellular scale participants deform in quite different ways from the intact left ventricular (LV) wall, in which they are embedded. The different deformations of different scales are nevertheless compatible with one another and mutually supportive. This chapter considers examples of the principal deformations present at subcellular, cellular, tissue, and macroscopic scales. In the wall of the LV as a whole, the orientations of the cardiomyocytes are helically arranged. Moving inward through the depth of the LV wall, there is a gradual change of cardiomyocyte orientations from left-handed helical in subepicardial layers, transitioning through circumferential in the mid myocardium, to right-handed helical orientations in the subendocardial layer. Additionally, the cardiomyocytes are aggregated in microscopically visible laminae, comprised of sheetlets separated by collagen-lined cracks or shear layers, orientated obliquely to the local wall plane. The collective swivelling of all sheetlets, from more wall-parallel orientations in diastole to more wall-perpendicular in systole, contributes to the marked systolic thickening of the LV wall seen in vivo. With the onset of diastole, as cardiomyocytes relax, the reorientations of sheetlets may also have a further role in facilitating myocardial perfusion. In contrast to the LV, the human right ventricle remains relatively non-compact and trabeculated. This chapter considers the clinical implications of the non-laminar and arguably more primitive arrangements of cardiomyocytes in trabeculations and papillary muscles.

Texto completoResumen
This chapter provides a novel observation concerning cross-linguistic variation regarding NP-ellipsis (henceforth NPE) inside articulated PPs and considers its theoretical implications. It first shows that although NPE is equally available in nominals in English, Chinese, and Japanese, the parallel pattern breaks down when NPE takes place within PPs. This study proposes a principled account of the cross-linguistic variation in question on the basis of (i) the layered internal structure of PPs, (ii) the syntactic reflection of fusional/non-fusional case morphology, and (iii) a phase-based analysis of ellipsis. The proposed analysis correctly predicts not only the availability of NPE within PPs but also one without PPs in English, Chinese, and Japanese. This chapter also provides theoretical implications for the role of phases in ellipsis and the cross-linguistic differences in nominal morphology.

Scientific databases and data warehouses store large amounts of data ith several tables and attributes. For instance, the Sloan Digital Sky Survey (SDSS) astronomical database contains a large number of tables with hundreds of attributes, which can be queried in various combinations (Papadomanolakis & Ailamaki, 2004). These queries involve many tables using binary operations, such as joins. To speed up these queries, many optimization structures were proposed that can be divided into two main categories: redundant structures like materialized views, advanced indexing schemes (bitmap, bitmap join indexes, etc.) (Sanjay, Chaudhuri & Narasayya, 2000) and vertical partitioning (Sanjay, Narasayya & Yang 2004) and non redundant structures like horizontal partitioning (Sanjay, Narasayya & Yang 2004; Bellatreche, Boukhalfa & Mohania, 2007) and parallel processing (Datta, Moon, & Thomas, 2000; Stöhr, Märtens & Rahm, 2000). These optimization techniques are used either in a sequential manner ou combined. These combinations are done intra-structures: materialized views and indexes for redundant and partitioning and data parallel processing for no redundant. Materialized views and indexes compete for the same resource representing storage, and incur maintenance overhead in the presence of updates (Sanjay, Chaudhuri & Narasayya, 2000). None work addresses the problem of selecting combined optimization structures. In this paper, we propose two approaches; one for combining a non redundant structures horizontal partitioning and a redundant structure bitmap indexes in order to reduce the query processing and reduce the maintenance overhead, and another to exploit algorithms for vertical partitioning to generate bitmap join indexes. To facilitate the understanding of our approaches, for review these techniques in details.

Abstract This paper deals with active vibration control of two identical flexible structures arranged in parallel. One of the authors had presented a vibration control mechanism so that two or more structures are connected via non-contact actuators in which one structure is utilized as a reaction wall for another structure’s control mutually. However, in such a mechanism, the control performance reduces as the natural frequencies of structures become closer. In this report, authors present a modified mechanism in which actuators are connected to the structures with long arms so that the direction of vibration in a mode differs on each structure. In this way, the reaction force from the actuator on structure is introduced to another structure for dissipative force even if the properties of structures are identical. Computer simulation and control experiment are carried out and the effectiveness of presented mechanism is confirmed.

Abstract The present paper introduces a decomposition procedure for the optimization of complex mechanical structures, where the coupling structure of the generated subsystems is assumed to be non-hierarchical. Since the above decomposition procedure is suitable for a parallel solution, it is implemented on a parallel computer. The procedure is applied to the shape optimization of a shell of revolution.

Texto completoResumen
Parallel iterative methods for fast solution of large-scale acoustic radiation and scattering problems are developed using exact Dirichlet-to-Neumann (DtN), nonreflecting boundaries. A separable elliptic nonreflecting boundary is used to efficiently model unbounded regions surrounding elongated structures. We exploit the special structure of the non-local DtN map as a low-rank update of the system matrix to efficiently compute the matrix-by-vector products found in Krylov subspace based iterative methods. For the complex non-hermitian matrices resulting from the Helmholtz equation, we use a distributed-memory parallel BICG-STAB iterative method in conjunction with a parallel Jacobi preconditioner. Domain decomposition with interface minimization was performed to ensure optimal interprocessor communication. For the architectures tested, and using the MPICH version of MPI, we show that when implemented as a low-rank update, the non-local character of the DtN map does not signicantly decrease the scale up and parallel eciency versus a purely approximate local boundary condition.

The immersed boundary methods are well known as an efficient flow solver for engineering problems involving fluid structure interactions. However, in order to obtain better results, higher resolutions near the immersed boundary points are desired. Non-uniform Cartesian mesh can easily fulfill this task without introducing a dramatic increase on the cost of computation and coding. In the current paper, an immersed boundary method with non-uniform Cartesian mesh is demonstrated. The Poisson problem is solved with assistance of a scientific parallel computational library PETSc. The code is validated with a three-dimensional flow over a stationary sphere. Then, a fluid-structure interaction model is coupled and validated with two-dimensional vortex induced vibration problems. Comparisons with previous studies are presented. The ultimate goal is to couple the fluid-structure interaction model with the three-dimensional immersed boundary method.
