Abstract:

In this paper we study properties of metric spaces. We consider the collection of all nonempty closed subsets, Cl(X), of a metric space (X,d) and topologies on C.(X) induced by d. In particular, we investigate the Hausdorff topology and the Wijsman topology. Necessary and sufficient conditions are given for when a particular pseudo-metric is a metric in the Wijsman topology. The metric properties of the two topologies are compared and contrasted to show which also hold in the respective topologies. We then look at the metric space R-n, and build two residual sets. One residual set is the collection of uncountable, closed subsets of R-n and the other residual set is the collection of closed subsets of R-n having n-dimensional Lebesgue measure zero. We conclude with the intersection of these two sets being a residual set representing the collection of uncountable, closed subsets of R-n having n-dimensional Lebesgue measure zero.

Abstract:

Several properties of Hausdorff continua are considered in this paper. However, the major emphasis is on developing the properties of the hyperspaces 2x and C(X) of a Hausdorff continuum X. Preliminary definitions and notation are introduced in Chapter I. Chapters II and III deal with the topological structure of the hyperspaces and the concept of topological convergence. Properties of 2x and C(X) are investigated in Chapter IV, while Chapters V and VI are devoted to the Hausdorff continuum X. Chapter VII consists of theorems pertaining to Whitney maps and order arcs in 2x. Examples of C(X) are provided in Chapter VIII. Inverse sequences of Hausdorff continua and of their hyperspaces are considered in Chapter IX.

Abstract:

End-users tend to lose their way in the maze of information within hypertext. Much work done to address the "lost in hyperspace" problem is reactive, that is, doing remedial work to correct the deficiencies within hypertexts because they are (or were) poorly designed and built. What if solutions are sought to avoid the problem? What if we do things well from the start? This thesis reviews the "lost in hyperspace" problem, and suggests a framework to understand the design and usability issues. These issues cannot be seen as purely psychological or purely computing, they are multi-disciplinary. The proactive, multi-disciplinary approach undertaken in this thesis is drawn from current technologies in sub-disciplines of hypertext, human-computer interaction, cognitive psychology and software engineering, and they include investigations into: " good design principles and guidelines for the building of hypertexts in the first place; " task analysis and user modelling techniques for end-users' tasks to be carefully defined; " effective hypertext structures to ensure usability of hypertexts; and " designer tools to create hypertexts with a reduced tendency for the "lost in hyperspace" problem to arise. To demonstrate these ideas, this thesis presents HyperAT, a hypertext research authoring tool, developed to help designers build usable web documents on the World Wide Web. The World Wide Web is chosen as a hypertext example since it is the most widely used and largest hypertext system ever. The approach taken in HyperAT is novel: multi-disciplinary approaches are integrated and implemented with a practical authoring tool. Evaluation of HyperAT indicates that it does address the "lost in hyperspace" problem, particularly for the World Wide Web by: (i) helping designers manage the complexity of the design and validation processes; and (ii) helping hypertext end-users navigate hypertexts produced by HyperAT without getting "lost".

Throesch, Elizabeth Lea. "The Scientific romances of Charles Howard Hinton : the fourth dimension as hyperspace, hyperrealism and protomodernism." Thesis, University of Leeds, 2007. http://etheses.whiterose.ac.uk/371/.

Full text

Abstract:

This thesis examines the epistemological, socio-cultural and aesthetic impact of the hyperspace philosophy of Charles Howard Hinton, as expressed within his two-volume collection of Scientific Romances (1884-1896). Hinton's hyperspace philosophy is founded on the belief that the fourth dimension exists as a transcendental yet material space that is accessible to both the mind and the physical senses. Inspired by Immanuel Kant's discussion of space as an a priori intuition, Hinton's project is one of consciousness expansion: he argues that 'a new era of thought' can be attained through the recognition of the fourth dimension. The thesis demonstrates that, in the Scientific Romances, Hinton seeks to engender the 'reality' of the fourth dimension within the reader's imagination through the collaboration of reader and author. Hinton's hyperspace philosophy is thus concerned with mediation, the ways in which the consciousness thinks and creates with and through the aesthetics of space. In addition to providing the most developed analysis of Hinton's writing to date, this thesis examines the work of Hinton's contemporaries exploring the ways in which the discourse of the fourth dimension can offer new readings of familiar literary texts. A recurring explanatory device throughout hyperspace philosophy is the dimensional analogy, and the thesis illustrates how this trope resonates across the work of contemporary writers including Lewis Carroll, H. G. Wells, HenryJames, Friedrich Nietzsche and William James.

Full text

Abstract:

Skeletal muscle is one of the most abundant tissues in the human body and it is responsible for the generation of voluntary movements and the control of body metabolism. Due its role and location, overstretching, trauma and excessive straining are responsible for muscle damage which is counterbalanced by considerable regenerative capabilities to preserve muscle function over time. Skeletal muscle regeneration requires the complex interplay between myogenic progenitors called Satellite cells (MuSC) and the surrounding interstitial cells whose activity is strictly coordinated by the inflamed environment of the damaged muscle. In Duchenne muscular dystrophy (DMD), the mutation in the dystrophin gene affects the tissue structural stability resulting in muscle damage caused by the daily wear and tear. In this context the early stage regenerative response that counterbalances muscle damage is replaced over time by fibrotic and fat tissues infiltration impairing muscle function. Among the interstitial cell populations, fibro Adipogenic Progenitors (FAPs) and vessel-associated myogenic progenitors (mesoangioblasts) are subjects of increasing interest. FAPs are considered as the source of fibrotic and fat tissue infiltrations concomitant with muscular dystrophy while mesoangioblasts are multipotent stem cells with the ability to differentiate in many mesoderm cell type including myocytes. This doctoral thesis aims at identifying and characterizing new compounds able to reshape the differentiation trajectories of these multipotent stem cells in order to counterbalance muscle impairment associated with pathological conditions. The identification of compounds able to increase mesoangioblasts (Mabs) myogenic potential or to decrease FAPs propensity to differentiate into adipose and fibrotic tissues would be of great relevance to counteract the consequences of muscle myopathies. To this end we used FAPs isolated from mdx mice (a model for DMD) and Mabs to perform two High-Content Screenings that can be employed to reshape and control the differentiation trajectories under small-molecule perturbation. We used automated fluorescence microscopy to monitor Mabs differentiation into three different lineages, (i.e., skeletal muscle, adipogenic progenitors and osteoblasts), promoted by small-molecules induction. Moreover, we used mdx FAPs, which spontaneously differentiate into adipocytes and fibroblasts in vitro, to identify small molecules able to decrease their differentiation potential. We have screened 560 compounds on Mabs and more than 5000 compounds on FAPs and we generated a list of “hit” molecules that can perturb the differentiation potential of these cells. Moreover, we have characterized different glucocorticoids for their ability to alter FAPs differentiation potential. Among them, while Budesonide inhibits adipogenesis, Halcinonide and Clobetasol show potential as drugs to inhibit fibrogenesis. Since these compounds are already used as drugs, although for the treatment of other disorders, their ability to impair FAPs differentiation could be potentially useful to counteract muscle degeneration in DMD. In the context of skeletal muscle differentiation and mesoangioblasts fate decision, the mitogen-activated protein kinases P38α/β, play a central role. P38α/β are involved in the regulation of MuSC activation, asymmetric division and their terminal differentiation in mature myotubes. Despite P38α/β importance in the regulation of these processes, the mechanisms behind its activation are still debated. Both cell-to-cell contact and TNF prime P38α/β phosphorylation and activation during myogenesis. Cell adhesion molecule-related/down-regulated by oncogenes (Cdo), a multifunctional surface protein, has been implicated in myogenesis. Following cell-to-cell contact and cadherin ligation, Cdo binds C-Junamino-terminal kinase-interacting protein 4 (JLP) and BCL2/adenovirus E1B 19 kDa protein-interacting protein 2 (Bnip-2) and both act as scaffolds for recruitment of P38 and Cdc42. The formation of this complex leads to the activation of Cdc42. Cdc42 switch from GDP to GTP results in the activation of the phosphorylation cascade leading to P38α/β activation. However, the molecular players involved in the signal transduction between the activated Cdc42 and the MAPK cascade are still not known. We focused on p21-activated kinase 1 (PAK1) a member of the p21 activated kinase family, which is a downstream effector of Cdc42. We found that the PAK1 inhibitor IPA-3 reduces P38α/β phosphorylation and myogenin expression during Mabs differentiation and this inhibition is accompanied by a delayed exit from the cell cycle. We demonstrated that IPA-3 treatment ultimately inhibits myogenic differentiation of Mabs, C2C12 cells and MuSC. Moreover, we found that mice treated with IPA-3 have a delayed recovery from cardiotoxin-induced muscle injury. These results support the hypothesis that PAK1 is involved in the in vivo myogenic differentiation program. We can speculate that P38α/β phosphorylation impairment by PAK1 inhibition, leading to regenerative impairment due to cell cycle exit failure, could drive an accumulation of activated satellite cells spared by the first round of regeneration but ready for the next one. Thus representing a considerable outcome as therapeutic application in muscle dystrophy in order to hinder and retard satellite cells exhaustion in muscular dystrophy affected patient.

Abstract:

Over the last several years a branch of Artificial Intelligence called Qualitative Reasoning has received much attention. A qualitative reasoner use qualitative values such as increasing, boiling and turbulent to analyze the behavior of physical systems. Existing qualitative frameworks have focused on physical systems whose qualitative values can be identified given the value of a single parameter. This precludes the application of qualitative models to physical systems whose properties require the values of several parameters. An example of such a system is the kinematics of a robotic manipulator. With this motivation, this thesis answers the following: What is a Qualitative model? Although current approaches appear diverse, they share a common mathematical foundation. This foundation is used to reformulate the qualitative model as a set of equivalence relations. The other question answered is: What extensions are needed to handle multivariate properties such as those encountered in the manipulator paradigm? The equivalence classes associated with qualitative models are geometrically shown to be connected hyperspaces. We show that existing frameworks are limited in the types of hyperspaces they can represent. The major ideas in this thesis are illustrated using manipulator kinematics.

Full text

Abstract:

The discovery of new geometries in the 19th century and the departure from an absolute to a relative understanding of space-time, together with the invention of higher dimensions have caused a shift towards the idealization of space. This new type of ideal space was called hyperspace. The counter-intuitive quality of hyperspace has opened up new formal possibilities and representation techniques in art and architecture. In a similar manner, with the introduction of computers, the virtual and immaterial quality of cyberspace has offered new design techniques and forms to architecture. Algorithmic design tools and the use of surface as the primary architectural element in cyberspace have caused a shift in the conception of space together with the way it is perceived. Taking its departure point from physical space, this thesis investigates the upper and lower dimensions of space in order to understand and analyze the current conception of architectural space in the virtual realm. Three types of spatial qualities are investigated in detail: the ideal characteristic of hyperspace, the visual medium of cyberspace and the algorithmic formation of hypospace.

Abstract:

In this work we analyze some selection principles over some classes of hyperspaces. In the first part we consider selective variations of tightness over a class of function spaces whose topologies are determined by bornologies on the space. As results, we extend several well known translations between covering properties and closure properties of the topology of pointwise convergence. In the second part we consider artificial hyperspaces that assist the analysis of productive topological properties. We emphasize the results characterizing productively ccc preorders and the characterization of the Lindelöf property via closed projections.

Na primeira parte consideramos variações seletivas do tightness sobre diversos tipos de espaços de funções, cujas topologias são determinadas por bornologias no espaço. Como resultados, estendemos diversas traduções conhecidas entre propriedades de recobrimento e propriedades de convergência na topologia da convergência pontual. Na segunda parte consideramos hiperespaços artificiais que auxiliam na análise de propriedades topológicas produtivas. Destacamos os resultados que caracterizam as pré-ordens produtivamente ccc e a caracterização da propriedade de Lindelöf em termos de projeções fechadas.

Citons parmi d'autres la topologie de Hausdorff pour les espaces métriques, la topologie de Vietoris, celle de Fell et celle de la convergence. Certains résultats complètent ceux de la monographie de E. Klein et A. Thompson. Le deuxième chapitre représente la partie originale de la thèse. Elle concerne l'étude de la coïncidence de la topologie co-compacte et la topologie supérieure de Kuratowski (consonance), et la coïncidence de la topologie de Fell et la topologie de la convergence (l'hyperconsonance). Il est aussi établi dans le cadre des espaces-points de type A (un espace-point est un espace séparé dénombrable ayant exactement un point limite), le rapport entre consonance et hyperconsonance. Le troisième chapitre est une étude des hyper-espaces de Fermes d'espaces métriques. On détaille les résultats de G. Beer sur les rapports entre la topologie de Fell, la topologie de Boule, les topologies classiques sur l'ensemble des fonctions distances et les limites de suites ordinaires de Fermes au sens de Kuratowski

Abstract:

Wireless communications systems underwent an evolution as the voice oriented applications evolved to data and multimedia based services. Furthermore, current wireless technologies, regulations and the un- derstanding of the technology are insufficient for the requirements of future wireless systems. Along with the rapid rise at the number of users, increasing demand for more communications capacity to deploy multimedia applications entail effective utilization of communications resources. Therefore, there is a need for effective spectrum allocation, adaptive and complex modulation, error recovery, channel estimation, diversity and code design techniques to allow high data rates while maintaining desired quality of service, and reconfigurable and flexible air interface technologies for better interference and fading management. However, traditional communications system design is based on allocating fixed amounts of resources to the user and does not consider adaptive spectrum utilization. Technologies which will lead to adaptive, intelligent, and aware wireless communications systems are expected to come up with consistent methodologies to provide solutions for the capacity, interference, and reliability problems of the wireless networks. Spectrum sensing feature of cognitive radio systems are a step forward to better recognize the problems and to achieve efficient spectrum allocation. On the other hand, even though spectrum sensing can constitute a solid base to achieve the reconfigurability and awareness goals of next generation networks, a new perspective is required to benefit from the whole dimensions of the available electro hyperspace. Therefore, spectrum sensing should evolve to a more general and comprehensive awareness providing a mechanism, not only as a part of CR systems which provide channel occupancy information but also as a communication environment awareness component of dynamic spectrum access paradigm which can adapt sensing parameters autonomously to ensure robust identification and parameter estimation for the signals over the monitored spectrum. Such an approach will lead to recognition of communications opportunities in different dimensions of spectrum hyperspace, and provide necessary information about the air interfaces, access techniques and waveforms that are deployed over the monitored spectrum to accomplish adaptive resource management and spectrum access. We define multidimensional signal analysis as a methodology, which not only provides the information that the spectrum hyperspace dimension in interest is occupied or not, but also reveals the underlaying information regarding to the parameters, such as employed channel access methods, duplexing techniques and other parameters related to the air interfaces of the signals accessing to the monitored channels and more. To achieve multidimensional signal analysis, a comprehensive sensing, classification, and a detection approach is required at the initial stage. In this thesis, we propose the multidimensional signal analysis procedures under signal identification algorithms in time, frequency. Moreover, an angle of arrival estimation system for wireless signals, and a spectrum usage modeling and prediction method are proposed as multidimensional signal analysis functionalities.

Abstract:

The goal of this research was to determine if the results of a simple comparison algorithm (SCA) could be improved by adding a hyperspace analogue to language model of memory (HAL) layer to form NCA. The HAL layer provides contextual data that otherwise would be unavailable for consideration. It was found that NCA did improve the results when compared to SCA alone. However, NCA added complexity problems that limit its practicality. The complexity of this algorithm is On3 where n is equal to the number of unique symbols in the data. While there is a relativity reasonable soft upper bound for the number of unique symbols used in a language, the complexity still limits the uses of the NCA combined algorithm. The conclusion from this research is that NCA can improve results. This research also suggested that the quality of results might increase as more data is processed by NCA.

Abstract:

In this text we shall be focusing on generalizing Martin-Löf randomness to computable metric spaces with arbitrary measure (for examples of this type of generalization see Gács [14], Rojas and Hoyrup [15]. The aim of this generalization is to define algorithmic randomness on the hyperspace of non-empty compact subsets of a computable metric space, the study of which was first proposed by Barmpalias et al. [16] at the University of Florida in their work on the random closed subsets of the Cantor space. Much work has been done in the study of random sets with authors such as Diamondstone and Kjos-Hanssen [17] continuing the Florida approach, whilst others such as Axon [18] and Cenzer and Broadhead [19] have been studying the use of capacities to define hyperspace measures for use in randomness tests. Lastly in section 6.4 we shall be looking at the work done by Hertling and Weihrauch [13] on universal randomness tests in effective topological measure spaces and relate their results to randomness on computable metric measure spaces and in particular to the randomness of compact sets in the hyperspace of non-empty compact subsets of computable metric spaces.

Abstract:

Cette thèse a pour objet le développement d’un écosystème d’oeuvres qui vise la génération de transformations à bord de futurs vols spatiaux de longue durée. Cet écosystème pourra concerner la transformation de l’atmosphère physique de ces voyages ainsi que la métamorphose de leur dimension humaine (tant sur le plan individuel, qu’intersubjectif et symbolique). L’hypothèse de travail considérée ici est celle des missions deep space (missions qui visent Mars, des lunes distantes, les points de Lagrange de systèmes divers ou autres destinations interplanétaires, pour des voyages ou séjours prolongés dans des vaisseaux, des bases, des stations – planétaires, lunaires, orbitales). Afin de mieux appréhender cette variété d’explorations du cosmos, son implication et son potentiel en termes d’expérience et de création artistique, cette recherche s’attache d’abord à explorer les relations des hyperobjets à l’hyperespace, avant de sonder les effets d’une circulation possible à partir d’un projet artistique proposé pour l’espace profond mais également pour des plateformes d’essais, des spaces analogues, ou encore des habitats sous-marins. Ce projet explore les passages entre les objets, les hyperobjets et l’hyperespace, ainsi que les relations possibles aux notions de dispositif, de machine abstraite, de climat, de transmédia, de dehors ou encore de Fiction Hors Science, à travers la proposition d’une time capsule pour futurs cosmonautes: Dark foam. Ce projet suggère une série d’expériences artistiques (film, exoclimat, environnement bioluminescent, lightworks, expériences sensorielles, script, log, pièces sonores) basées sur le développement d’une fiction : Swimming the rings of a gas hypergiant. Il s’agit avec cette fiction de développer une expédition commune (de la Terre à l’espace) ainsi qu’un imaginaire extrasolaire dont le contenu, les modes d’existence et d’activation, proposent de nouvelles voies de recherche en ce qui concerne l’intégration de l’art aux vols spatiaux, les échanges Terre-espace ainsi que la collaboration cosmonaute-artiste. Ce projet est destiné à augmenter (par une série de nébulisations, et par la mise en place de boucles planète-espace) la sensibilité spatiale expérimentée et générée par une future mission habitée. En questionnant le rôle et le statut de l’art et des voyages spatiaux, ce projet peut amener à une reformulation de la vision de l’atmosphère et de l’espace, ainsi qu’à une possible transformation de notre relation à l’environnement cosmique. L’image de cette relation est alors définie comme sombre, produit d’une topologie spéculative – topologie de l’écume qui sous-tend le développement du projet artistique. Cette time capsule est un projet évolutif qui pourra contribuer à alimenter le design et la préparation d’une mission future, être embarquée par un cosmonaute pour une expérimentation directe, ou encore générer diverses expériences de pensée et expérimentations artistiques sur la planète
This study develops an ecosystem of works that aims at generating transformations within the framework of future deep space missions. This ecosystem may concern the transformation of the physical atmosphere as well as the human (individual, intersubjective and symbolic) dimension of these travels. The working hypothesis considered here is based on future missions targeting Mars, distant moons, Lagrangian points or other interplanetary destinations – for extended stays in spacecrafts and planetary, lunar and orbital stations or bases. In order to better understand this variety of explorations of the cosmos, its implication as well as its potential in terms of experience and artistic creation, this research first seeks to explore the relationships between hyperobjects and hyperspace, before probing the effects of a possible loop circulation emerging from the artistic project, which is developed to interact with diverse deep-space situations, space analogues, testbeds and underwater habitats on the planet. Entitled Dark foam, this project explores through the proposal of a time capsule for future cosmonauts the transitions between objects, hyperobjects and hyperspace, as well as its possible relations to the notions of dispositif, abstract machine, climate, transmedia, outdoors and Fiction Hors Science (fiction beyond science). This time capsule suggests a series of artistic experiences (film, exoclimate, bioluminescent environment, lightworks, sensorial experiences, script, log, sonic pieces) based on an extrasolar fiction: Swimming the rings of a gas hypergiant. This fiction develops a common expedition from Earth to space, it draws on an extrasolar imaginaire whose content and modes of existence and activation could propose new directions for future art and space research and cosmonaut-artist collaboration. This project is conceived to enhance – through a series of nebulizations and by the establishment of a field of planet-space loops – the spatial sensibility both experienced and generated by a future inhabited mission.By questioning the role and status of both art and space exploration, this project could lead to the reformulation of our position in space and hyperspace, our view of the atmosphere and our relationship to the cosmic environment.The image of this relationship is defined as dark, being the product of a speculative topology – a foam topology that underlies the development of the artistic project. This time capsule is an evolving project that can contribute to foster the design and preparation of a future mission, that can be embarked by a cosmonaut for direct experimentation, that can be tested within specific space analogs and generate various thought and artistic experiments on the planet

Abstract:

En los últimos años se ha desarrollado una teoría matemática que permite generalizar algunas teorías matemáticas clásicas: hiperespacios, espacios de funciones, topología algebraica, etc. Este hecho viene motivado, en parte, por ciertos problemas de análisis funcional, concentración de medidas, sistemas dinámicos, teoría de las ciencias de la computación, matemática económica, etc. Esta tesis doctoral está dedicada al estudio de algunas de estas generalizaciones desde un punto de vista no simétrico. En la primera parte, estudiamos el conjunto de funciones semi-Lipschitz; mostramos que este conjunto admite una estructura de cono normado. Estudiaremos diversos tipos de completitud (bicompletitud, right k-completitud, D-completitud, etc), y también analizaremos cuando la casi-distancia correspondiente es balanceada. Además presentamos un modelo adecuado para el computo de la complejidad de ciertos algoritmos mediante el uso de normas relativas. Esto se consigue seleccionando un espacio de funciones semi-Lipschitz apropiado. Por otra parte, mostraremos que estos espacios proporcionan un contexto adecuado en el que caracterizar los puntos de mejor aproximación en espacios casi-métricos. El hecho de que varias hipertopologías hayan sido aplicadas con éxito en diversas áreas de Ciencias de la Computación ha contribuido a un considerable aumento del interés en el estudio de los hiperespacios desde un punto de vista no simétrico. Así, en la segunda parte de la tesis, estudiamos algunas condiciones de mejor aproximación en el contexto de hiperespacios casi-métricos. Por otro lado, caracterizamos la completitud de un espacio uniforme usando la completitud de Sieber-Pervin, la de Smyth y la D-completitud de su casi-uniformidad superior de Hausdorff-Bourbaki, definida en los subconjuntos compactos no vacíos. Finalmente, introducimos dos nociones de hiperespacio casi-métrico fuzzy.

Abstract:

Cette thèse se consacre premièrement à certains aspects de la définition de charges conservées en relativité générale pour les espaces asymptotiquement plats à l’infini spatial. À l’aide de la dualité gravitationnelle, présente au niveau linéarisé, on étudie également l’existence de charges topologiques, magnétiques, ainsi que leurs contributions aux superalgèbres dans les théories de supergravité N = 1 et N = 2 à quatre dimensions. La thèse est divisée en trois parties.

Dans la première partie, les espaces asymptotiquement plats à l’infini spatial sont décrits à l’aide d’une généralisation de la métrique de type Beig-Schmidt. La construction de charges à partir de l’étude des équations du mouvement et de la classification de tenseurs symétriques et de divergences nulles nous permet de démontrer l’unicité des charges de Poincaré pour l’ansatz non-généralisé en présence de conditions de parité. L’équivalence des charges de Ashtekar- Hansen et Mann-Marolf est ainsi revisitée. Dans le cas d’un ansatz généralisé, une régulation de la forme symplectique divergente, à l’aide de contre-termes rajoutés à l’action de Mann-Marolf, nous donne la possibilité de considérer un espace des phases sans conditions de parité, tout en gardant un principe variationnel bien défini. Le groupe asymptotique comprend alors, en plus des charges de Poincaré où les charges de Lorentz ne sont plus asymptotiquement linéaires, des charges non-triviales associées aux supertranslations et aux transformations logarithmiques.

Dans la deuxième partie, on étudie la dualité gravitationnelle et la définition de charges magnétiques en gravitation linéarisée. On revisite la dualité et on montre qu’une dualisation sur les indices de Lorentz facilite la compréhension de celle-ci. Les dix charges de Poincaré ainsi que leurs duales magnétiques sont alors exprimées en termes d’intégrales de surface. Nous illustrons ensuite nos résultats à travers l’étude des sources de certaines solutions électriques et de leur duales magnétiques. Les solutions électriques envisagées sont :les trous noirs de type Schwarzschild et de type Kerr ainsi que les ondes de chocs de type pp.

Dans la dernière partie, on établit la supersymétrie des espaces de type Taub-NUT lorentzien chargés électriquement et magnétiquement dans la supergravité N = 2. Motivé par l’existence d’une égalité BPS, on entreprend alors une recherche sur l’inclusion de la charge NUT dans l’algèbre de supersymétrie. Grâce à une complexification de la forme de Witten-Nester, cette contribution de la charge NUT à la superalgèbre est comprise comme une déformation topologique, symétrique, au crochet antisymétrique des super-charges. Ce résultat est alors appliqué à la superalgèbre N = 1 à travers l’étude des ondes de chocs de type pp.

Abstract:

O Paradigma Orientado a Objetos tem sido atualmente a abordagem dominante de desenvolvimento de software. Contudo, ela sofre da Tirania da Decomposição Dominante, pois não permite uma modularização adequada da implementação relativa a interesses estruturais. Como consequência, a implementação relativa a cada interesse estrutural fica espalhada pelos módulos do programa e entrelaçada com a implementação relativa a outros interesses estruturais. Outras abordagens de desenvolvimento de software, como o Desenvolvimento de Software Orientado a Aspectos com AspectJ e a Separação Multidimensional de Interesses em Hiperespaços com Hyper/J e CME, atingem sucesso moderado em oferecer mecanismos que permitem superar as deficiências do Paradigma Orientado a Objetos. No entanto, tais abordagens também possuem deficiências e omissões que devem ser reparadas para que elas possam se tornar utilizáveis em contextos típicos de desenvolvimento de software complexo. Este trabalho especifica uma nova abordagem, denominada Desenvolvimento de Software Orientado a Temas (DSOT), que tem como objetivo superar algumas deficiências das abordagens anteriores por meio de mecanismos que permitem a manipulação da implementação de cada interesse estrutural de forma separada e a manipulação da implementação de cada tipo de dado de forma separada. Além disso, DSOT possui operadores que são ortogonais, isto é, podem ser utilizados de forma combinada ou separada, para efetuar a composição de módulos do programa. Mostra-se o modelo conceitual do DSOT e descrevese um estudo de caso que consiste no desenvolvimento de um programa para demonstrar mais concretamente como o DSOT funciona na prática. Não se demonstra a superioridade do DSOT para o caso geral, mas os resultados alcançados evidenciam que o DSOT é uma abordagem promissora que merece ser investigada mais aprofundadamente em pesquisas futuras
The Object-Oriented Paradigm has currently been the dominant approach for developing software. However, it suffers from the Tyranny of the Dominant Decomposition, as it does not support a suitable modularization to the implementation relative to structural concerns. As a consequence, the implementation relative to each structural concern is scattered throughout the program modules and tangled with the implementation relative to other structural concerns. Some software development approaches, such as Aspect-Oriented Software Development with Aspect and Multidimensional Separation of Concerns in Hyperspaces with Hyper/J and CME, achieve moderate success in offering mechanisms that make it possible to overcome the deficiencies of the Object-Oriented Paradigm. However, such approaches also possess deficiencies and ommissions that must be corrected in order for them to get usable in typical complex software development contexts. This work specifies a new approach, named Theme- Oriented Software Development (TOSD), which aims at overcoming some deficiencies from previous approaches through mechanisms that support the handling of implementation for every structural concern separately and the handling of implementation for every data type separately. Moreover, TOSD contains operators which are orthogonal, that is, they can be used separately or as a combination, in order to perform composition of the program modules. We show the conceptual model of TOSD and describe a case study which consists in the development of a program to demonstrate more concretely how TOSD works in practice. We do not demonstrate the superiority of TOSD for the general case, but the results we have obtained suggest that TOSD is a promissing approach which deserves a deeper investigation in future research

Let X be a Banach space. Suppose K is a compact convex subset of X, and T:K K is nonexpansive, then it was proved by S. Ishikawa that for any K,the sequence { } defined by = converges to a fixed point of T. Also given any compact subset M of X the classical Mazur theorem states that, the closed convex hull of M, conv(M) is also compact. We shall prove that the above-mentioned results are extendable to the hyperspace(CC(X), h) where CC(X)is the collection of all non-empty compact convex subsets of X and h is the Hausdorff metric induced by the norm on X. Next, suppose K is a weakly compact, convex subset of X and :(K, ) (K, )is a commutative family of continuous linear transformations, then has a common fixed point by Markov- Kakutani theorem. We shall show that for each :(CC(X),h) where

Abstract:

This paper explores the intersection of psychology and religion in late-Victorian Britain through the life of medical psychologist and lay religious author, Dr. Alfred Taylor Schofield. Extending the work of recent scholarship on the contested nature of nineteenth-century sciences of mind, this study focuses on the interplay between popular and professional communities engaged in discourse over mind/body issues and the unconscious mind, and the relevance of these contemporary topics to debates over the certainty of natural versus supernatural knowledge. In the period between 1890 and 1910, when psychology (‘the new psycho-physiology,’ in Britain) emerged as an autonomous scientific discipline separate from its past disciplinary home within moral philosophy, the application of psychology within medicine (early psychiatry) encountered institutional and philosophical impediments that hindered the incorporation of psychodynamic theories and new psychotherapeutic regimens into medical curriculum and clinical practice. This paper examines the rising cultural phenomena of faith healing, the responses of religious and medical communities to popular healing movements, and the implications that these movements had for both the development of early psychiatry as well as for contemporary transformations in religious sensibilities. Utilizing the unique position of A.T. Schofield, who straddled a popular-professional divide in mediating between medical and lay religious communities, this paper seeks to explain how the proliferation of popular healing movements provoked professional interest in new psychotherapies while psycho-physiological explanations of faith healing altered lay religious understandings of ‘miracles’ and transcendental knowledge.
