Pełny tekst źródłaThis thesis focuses mainly on online matching problems, where sets of resources are sequentially allocated to demand streams. We treat them both from an online learning and a competitive analysis perspective, always in the case when the input is stochastic.On the online learning side, we study how the specific matching structure influences learning in the first part, then how carry-over effects in the system affect its performance.On the competitive analysis side, we study the online matching problem in specific classes of random graphs, in an effort to move away from worst-case analysis.Finally, we explore how learning can be leveraged in the scheduling problem
Scetbon, Meyer. "Advances in Optimal Transport : Low-Rank Structures and Applications in Machine Learning". Electronic Thesis or Diss., Institut polytechnique de Paris, 2023. http://www.theses.fr/2023IPPAG002.
Pełny tekst źródłaRecent advances in hardware, such as the development of highly-parallel accelerators, and the growing permeabilitybetween computer science, statistics, optimization and applied mathematics have brought forward a new generation of tools,capable of addressing increasingly complex machine learning (ML) problems. Among these new challenges, some require the comparison of point clouds or probability measures. Optimal transport (OT) has become a widely used tool in this context due to its ability to provide a natural geometry in the space of distributions and offer a new perspective for dealing with ML problems when lifted into this space. Starting from a cost function (e.g. a distance) on the space on which measures are supported, OT consists in finding a mapping or coupling between both measures that is optimal with respect to that cost. In other words, OT naturally extends the ground cost between two points to a discrepancy function between histograms of points, or probability measures, in the form of an optimization problem. Further, as a consequence of its strong geometric component, OT is the object of a rich mathematical theory regarding its metric and topological properties, on which ML practitioners can rely to build and study their models.Yet, in their original form, as proposed by Kantorovich, OT distances are not well suited for applied problems: (i) computing OT between discrete distributions amounts to solving a large and expensive network flow problem which requires a supercubic complexity; (ii) estimating OT using sampled measures is doomed by the curse of dimensionality: the sample convergence rate of OT is exponentially slow w.r.t. the dimension of the ambient space, therefore OT is likely to be meaningless when used on samples from high-dimensional densities. Despite these challenges, OT has shown great promise in various machine learning applications, and ongoing research is aimed at addressing these challenges and making OT more accessible and usable in practice.The main approach to alleviate these issues consists in regularizing the optimization problem using an entropic regularization. By adding entropy to the objective function, one can now solves a regularized version of the OT problem in quadratic time and memory using the Sinkhorn algorithm. In addition, this regularization allows to avoid the curse of dimensionality as long as enough entropy has been added.Even though entropic regularization has improved both the computational cost and the statistical properties of optimal transport, it still suffers from a quadratic complexity that prevents its use for large-scale applications. One guiding principle of this thesis is that there are still many research opportunities to develop new algorithmic tools that can exploit or extend this way of thinking in order to make OT applicable to large-scale problems.This thesis consists of two main parts. In the first part, we propose new regularization schemes of the OT problem and its quadratic variant, namely the Gromov-Wasserstein (GW) problem, by considering low-rank factorization of both the underlying cost and the coupling solving the OT problem itself. These new computational schemes pave the way for the use of OT in the large-scale setting. In the second part, we show that OT can also offer new perspective on longstanding ML problems once lifted into the set of distributions. We adopt this point of view on two applied problems in fairness and robustness respectively and propose new approaches to tackle them using OT

Language and consciousness enrich our lives. But they are rare commodities; most creatures are language-less and unconscious. This dissertation is about the conditions that distinguish the haves from the have-nots. The semantic properties of a natural language expression are determined by conventions governing the way speakers use the expression to communicate information. The capacity to speak a language involves highly specialized (perhaps even modular) cognition. Some authors think that one cannot consistently accept both views. In Chapter 1 ('Content and Competence') I explain why one can. According to the convention-based theory of content determination, propositions are fit to be the contents of both thought and speech. Recently, this view has been challenged. The challenge exploits a series of observations about what it takes to understand semantically incomplete sentences. In Chapter 2 ('Speaker Meaning in Context'), I explain how the challenge can be met. Physicalists seem to owe an explanatory debt. Why should psychophysical relations appear contingent? In Chapter 3 ('There Couldn't Have Been Zombies, but it's a Lucky Coincidence That There Aren't') I pay the debt on their behalf. My explanation proceeds in three steps. First, I observe that there are necessary coincidences, or accidents. Second, I show that traditional epistemological arguments for dualism merely establish that phenomenal states and corresponding physical states are accidentally, or coincidentally, related. Finally, I suggest that inattention to the distinction between coincidence/accidentality and contingency results in frequent equivocation. Thus the disposition to (correctly) judge that psychophysical relations are coincidences manifests itself as a disposition to (incorrectly) judge that psychophysical relations are contingent. In Chapter 4 ('Zombies are Inconceivable') I deny that psychophysical relations appear contingent. The chapter begins with an argument to the effect that zombies cannot be coherently conceived. I then consider and reject various ways of resisting the argument.

As processors scale deep into the multi-core and many-core regimes, bandwidth and energy-efficiency of the on-die interconnect network have become paramount design issues. Recognizing potential limits of electrical interconnects, emerging nanophotonic integration has been recently proposed as a potential technology option for both on-chip and chip-to-chip applications. As optical links avoid the capacitive, resistive and signal integrity limits imposed upon electrical interconnects, the introduction of integrated photonics allows for efficient realization of physical connectivity that are costly to accomplish electrically. While many recent works have since cited the potential benefits of optics, inherent design tradeoffs of photonic datapath and backend components remain relatively unknown at the system-level. This thesis develops insights regarding the behavior of electrical and hybrid optoelectrical networks and systems. We present power and area models that capture the behavior of electrical interface circuits and their interactions with optical devices. To animate these models in the context of a full system, we contribute DSENT, a novel physical modeling framework capable of estimating the costs of generalized digital electronics, mixed-signal interface circuitry, and optical links. With DSENT, we enable fast power and area evaluation of entire networks to connect the dynamics of an underlying photonics interconnect to that of an otherwise electrical system. Using our methodolody, we perform a technology-driven design space exploration of intra-chip networks and highlight the importance of thermal tuning and parasitic receiver capacitances in network power consumption. We show that the performance gains enabled by photonics-inspired architectures can enable savings in total system energy even if the network is more costly. Finally, we propose a photonically interconnected DRAM system as a solution to the core-to-DRAM bandwidth bottleneck. By attacking energy consumption at the DRAM channel, chip, and bank level with integrated photoncis, we cut the power consumption of the DRAM system by 10x while remaining area neutral when compared to a projected electrical baseline.

The response of grooved composite laminates to out-of-plane contact loading is examined using numerical modeling through the consideration of contact pressure and stresses within the laminate, with particular focus on the area local to the groove. Finite element analysis is employed via ABAQUS, a commercial finite element modeling software. The indentor is modeled as a rigid body, and the validity of this approximation is assessed through comparison with a deformable, linear elastic indentor. The influence of ply angle is investigated through consideration of a family of [+/-[theta]/0]13s laminates for values of [theta] of 15°, 30°, 45°, and 60°, along with a quasiisotropic [+/-45/0/90]10s and a crossply [0/90]20s configuration, all using T700/2510 graphite/epoxy. The linearity of the response is investigated, and two loading configurations are studied and compared: a two-dimensional, cylinder-loaded configuration, and a three-dimensional, sphere-loaded configuration. Results show that the Hertzian contact model for isotropic bodies cannot be used to determine contact pressure due to an inability of that model to analytically determine the appropriate contact length. The basic form of the contact pressure curve is similar to the Hertzian model, but with significant local variations superposed due to stiffness variation, particularly in the longitudinal direction, due to ply orientation angle. Thus, if the contact length is supplied, the Hertzian model can be a valid overall approximation. Total vertical load magnitude is determined to be a primary factor in the response, as it determines contact length, and thus the distribution of contact pressure and the form of the stress field. The response is found to vary with significant nonlinearity with respect to applied load due to the relationship with contact length. The rigid body approximation of the steel indentor is deemed sufficiently accurate to capture the overall behavior, due to the high difference in stiffness between the steel indentor and the through-thickness stiffness of the composite. There is significant variation between the two-dimensional models and the three-dimensional models, particularly in determining the magnitude of the response. However, the two-dimensional model is sufficient to observe trends, and could be of use in preliminary design and analysis, although the full three-dimensional model is required to accurately determine the response in the final analysis, largely due to important issues of variation along the groove. In general, stress behavior is dependent on the laminate and the particular stress, with stress fields between laminates showing some similar trends, but also high variability depending on the composition of the laminate.

Pełny tekst źródłaThe speaker in the poem "Mending Wall" by American poet Robert Frost questions the wisdom of the saying that "Good Fences Make Good Neighbo[u]rs" (1914 North of Boston lines 27 and 45). The walls or fences referred to in the poem represent more than just physical barriers separating adjacent premises; the speaker sees them as representing obstacles to communication and friendship between individuals. Seen from the perspective of the speaker, a fence or wall is a "bad" thing. But the speaker is but one of the parties to the neighbourly relationship. For the speaker's neighbour, a wall or a fence is "a protector of privacy" (Watson "Frost's Wall : The View from the Other Side" 1971 44 The New England Quarterly 653 655). Thus there are two views on walls or fences: they can be seen negatively as obstructing good relations, or positively as dividers that secure good relations between neighbours by separating them and protecting their privacy rights.

Pełny tekst źródłaPeople with developmental language disorder (DLD) have difficulties understanding language and expressing themselves. These difficulties, which are not associated with another disorder, significantly impact their everyday functioning. For young adults, they may translate into challenges during the school-to-worktransition. As of now, little is known regarding the factors that may explain why some people with DLD succeed during this transition, while others experience major difficulties. This dissertation aims to better understand this life period for this population, under the lens of self-determination theory (SDT). The main purpose is to validate a motivational model of school-to-work transition, in which autonomy support from different sources predicts the young adult’s motivation toward the job search, which is subsequently associated with the transition success and psychological well-being. It includes three articles. The first article presents an integration of the three theories on which this dissertation is grounded, namely the Human Development Model – Disability Creation Process 2 (HDM-DCP2), the capability approach, and self-determination theory. The agency model is suggested to support the optimal development and well-being of people with disabilities. The second article is a systematic review of the outcomes of young adults with DLD that synthesizes the strengths and challenges of this population in three life domains, including employment. The predictive role of language abilities, evaluated for each domain, remains limited. Finally, to meet the objectives of this dissertation, the third article presents the results of a retrospective study (37 young adults with DLD) and a prospective study (218 students in their final year of the Work-Oriented Training Path [WOTP], including 52 with DLD). Overall, the results supported the motivational model. In the prospective study, the analyses were conducted on the whole sample because participants with DLD were similar to their peers in the WOTP on all the measured variables. Specifically, autonomy support from the father and from friends was associated to autonomous motivation toward job search in both studies, as well as autonomy support from the teachers in the retrospective study. Autonomous motivation was subsequently associated with psychological well-being in both studies, and with the success of the school-to-work transition in the prospective study. These relations were also observed for controlled motivation. The absence of relation between motivation and the success of the transition in the retrospective study could be related to environmental obstacles that these young adults encountered on the job market in the long run. This dissertation thus evidences the relevance of self-determination theory in the study of school-to-work transition of young adults with DLD. Autonomy support and motivation partly explain the school-to-work transition success and psychological well-being. These findings have important theoretical, methodological, and practical implications that are discussed. Further research avenues are also suggested.

Pełny tekst źródła[ES] El propósito fundamental que se ha perseguido en esta tesis es el de realizar una indagación, observada desde el prisma del intérprete, de Catalogue d¿oiseaux, utilizando su segundo y cuarto cuaderno como objeto de estudio a la hora de abordar su enfoque estético y pianístico. La necesidad de aproximarse a la obra desde una óptica interpretativa surge de la paradoja existente entre la importancia que esta composición ocupa en el catálogo compositivo de Olivier Messiaen y el peso real que la partitura posee entre los pianistas actuales. Debido a la evolución del lenguaje compositivo del autor, que se plasma en una mayor complejidad conceptual, Catalogue d¿oiseaux genera una serie de interrogantes de orden interpretativo que la alejan del resto de la producción pianística "tradicional". Este factor se traduce, frecuentemente, en apriorismo y axiomas que generan visiones excesivamente polarizadas sobre la ejecución de la obra. Para solventar este atrincheramiento entre planteamientos antagónicos, se ha empleado una metodología basada en trazar una "idea de obra" a través del estudio de la ubicación temporal de la composición, el análisis formal y la apreciación de las transcripciones ornitofónicas. Este encuadre de índole teórico actúa de vehículo para desgranar la naturaleza interpretativa de Catalogue, donde acercarse a las transcripciones, entender la importancia del elemento temporal y asimilar la escritura de estos dos cuadernos sirven de herramientas para revelar una creación musical mucho más abierta, aspecto que se corrobora con el estudio la tradición interpretativa de la obra. Todo ello muestra una composición que escapa de postulados simplistas, ofreciendo al pianista un universo de posibilidades interpretativas que supera cualquier viejo debate en torno a la ejecución de esta partitura colosal de la literatura pianística. El estudio llevado a cabo cristaliza con la grabación sonora de ambos cuadernos, así como la inclusión de ambas piezas dentro de un recital para el ciclo de "Jóvenes Intérpretes" del Teatro de la Maestranza de Sevilla. Del mismo modo, parte del material de investigación ha servido para la confección de dos artículos para la revista Melómano que se incluyen como anexos, así como la impartición de una serie de conferencias-conciertos alrededor del pianismo de Olivier Messiaen en diversos conservatorios y universidades españolas el próximo año 2017 con motivo del 25º aniversario de la muerte de Olivier Messiaen.
[CAT] El propòsit fonamental que s'ha perseguit en aquesta tesi és el de realitzar una indagació, observada des del prisma de l'intèrpret, de Catalogue d¿oiseaux, utilitzant el seu segon i quart quadern com a objecte d'estudi a l'hora d'abordar el seu enfocament estètic i pianístic. La necessitat d'aproximar-se a l'obra des d'una òptica interpretativa sorgeix de la paradoxa existent entre la importància que aquesta composició ocupa en el catàleg compositiu d'Olivier Messiaen i el pes real que la partitura posseeix entre els pianistes actuals. A causa de l'evolució del llenguatge compositiu de l'autor, que es plasma en una major complexitat conceptual, Catalogue d¿oiseaux genera una sèrie d'interrogants d'ordre interpretatiu que l'allunyen de la resta de la producció pianística "tradicional". Aquest factor es tradueix, freqüentment, en apriorisme i axiomes que generen visions excessivament polaritzades sobre l'execució de l'obra. Per a solucionar aquest atrinxerament entre plantejaments antagònics, s'ha emprat una metodologia basada a traçar una "idea d'obra" a través de l'estudi de la ubicació temporal de la composició, l'anàlisi formal i l'apreciació de les transcripcions ornitofòniques. Aquest enquadrament d'índole teòric actua de vehicle per a desgranar la naturalesa interpretativa de Catalogue, on acostar-se a les transcripcions, entendre la importància de l'element temporal i assimilar l'escriptura d'aquests dos quaderns serveixen d'eines per a revelar una creació musical molt més oberta, aspecte que es corrobora amb l'estudi la tradició interpretativa de l'obra. Tot açò mostra una composició que escapa de postulats simplistes, oferint al pianista un univers de possibilitats interpretatives que supera qualsevol vell debat entorn de l'execució d'aquesta partitura colossal de la literatura pianística. L'estudi dut a terme cristal·litza amb l'enregistrament sonor de tots dos quaderns, així com la inclusió d'ambdues peces dins d'un recital per al cicle de "Joves Intèrprets" del Teatre de la Maestranza de Sevilla.

Pełny tekst źródłaEl proyecto adquiere otra condición que es la de moldear y formular determinadas hipótesis sobre
su uso y su contenido. Se trata de propuestas pioneras en su formulación programática. El proyecto no se limita a organizar y asignar espacios a un programa, sino que en sí, también actúa sobre la organización del edificio. La dificultad que conlleva la determinación unilateral por parte del arquitecto del uso colectivo y social repercutirá en la evolución posterior de la obra. El contenido, por tanto, también se escabulle de las certezas del proyecto.
Como fenómeno económico, ya los primeros modernos abandonaron la aspiración de taylorizar la construcción, apostando por una industria semi-prefabricada en la que la relación de la arquitectura con la construcción es de denegación: nace de ella y la necesita para violentarla o llevarla al límite.
Se trata de un fenómeno económico de difícil predicción y que genera conflictos en la obra porque la industria de la construcción busca su rentabilidad en la optimización de las soluciones y acude al catálogo para resolver problemas conocidos. La flexibilidad de esta industria para abordar problemas nuevos es casi excepcional y está poco estimulada y así la obra difícilmente se inscribe en una economía de la prescripción, condicionada además por factores de beneficio y velocidad.
En definitiva, el análisis comparativo de estos dos ejemplos muestra como, la progresiva complejidad tecnológica, la especialización -que cuenta con un protagonismo activo y renovado de
la figura del ingeniero-, la implantación de nuevos programas, la dificultad de anticipar el fenómeno económico de la construcción y la variabilidad de los clientes son algunos de los vectores de incertidumbre que acompañaron el desarrollo de sus respectivos procesos de materialización, en un marco colectivo de la creación arquitectónica y en un contexto público de su trascendencia. Ante esta nueva situación que se genera a partir de la segunda mitad del siglo XX, la arquitectura y en definitiva los arquitectos, buscan nuevos respuestas. La ópera de Sydney y el Beaubourg de París anuncian caminos de distinto carácter.
Ante esta realidad hemos podido adivinar algunos mecanismos al alcance del proyecto y del arquitecto en el estudio de los ejemplos de referencia. El proyecto se fragmenta, adopta geometrías deformables, adquiere un carácter estratégico, anima a la recuperación de espacios de colaboración transversales entre los distintos agentes y fundamentalmente entre arquitectos e ingenieros... Todo ello se hace imprescindible para la coherencia final del objeto arquitectónico.
La arquitectura entendida como realidad ya no podrá ser sólo concebida. A partir de la segunda mitad del siglo XX deberá ser, además, construida, porque sólo así habrá sido capaz de transformarse, sortear o incorporar las dificultades y posibilidades que han surgido durante su proceso constructivo. El cómo haya sido capaz de atravesar ese tránsito será, al menos, igual de importante para el resultado final que el punto de partida. Si Le Corbusier afirmaba que "l'important c'est le choix", la pérdida de control del proyecto sobre el producto arquitectónico obliga a ampliar esa condición para una arquitectura posible.
After the analysis of the construction of the project by the moderns and its relation with the architectural promise in some of the works built by its masters, the thesis makes a sistematic study of the constuction of the Sydney Opera House and the Pompidou Centre in Paris. From this analysis, we emphasise a whole host of circumstances that give rise to the transformation of the architectural project during its building process. Nevertheless, the existence of points in common and the structural character of some of them allow us to suspect a situation in architecture¾at least in the second half of the 20th century¾in which we might question the project understood as a worthy and complete anticipation of its realisation. The project foregrounds the twin task of separating and grouping assignments and kinds of knowledge in the multiple agents who come together on the building site. Their effectiveness will reside in the extent to which it is known how to establish the right conditions for the convergence of all these specialists. The participation becomes indispensable of the figure of an engineer committed to the project and who is capable of incorporating in the latter the technical complexity of a form not only compatible with, but also active in, its definition. From the point of view of the architectural object, of the container, the project understood as a fixed technical document is no longer either complete or infallible.
The project acquires another quality, which is that of shaping and formulating certain hypotheses on its use and its content.
The project is not restricted to organising and assigning spaces to a programme but rather it also acts in itself on the organisation of the building.

Pełny tekst źródłaAfter the analysis of the construction of the project by the moderns and its relation with the architectural promise in some of the works built by its masters, the thesis makes a sistematic study of the constuction of the Sydney Opera House and the Pompidou Centre in Paris. From this analysis, we emphasise a whole host of circumstances that give rise to the transformation of the architectural project during its building process. Nevertheless, the existence of points in common and the structural character of some of them allow us to suspect a situation in architecture¾at least in the second half of the 20th century¾in which we might question the project understood as a worthy and complete anticipation of its realisation. The project foregrounds the twin task of separating and grouping assignments and kinds of knowledge in the multiple agents who come together on the building site. Their effectiveness will reside in the extent to which it is known how to establish the right conditions for the convergence of all these specialists. The participation becomes indispensable of the figure of an engineer committed to the project and who is capable of incorporating in the latter the technical complexity of a form not only compatible with, but also active in, its definition. From the point of view of the architectural object, of the container, the project understood as a fixed technical document is no longer either complete or infallible. The project acquires another quality, which is that of shaping and formulating certain hypotheses on its use and its content.The project is not restricted to organising and assigning spaces to a programme but rather it also acts in itself on the organisation of the building. The difficulty that comes with the unilateral fixing on the part of the architect of the collective and social use of the building will have repercussions in its subsequent evolution. The content, then, slips away from the certainties of the project.

Pełny tekst źródłaThe Great East Japan Earthquakes unique scope and the actors involved in the ensuing disaster dispatch has the potential to significantly impact four areas influencing the SDFs trajectory security interests, economic interests, norms, and actors and institutions. Retrenchment, status quo, and remilitarization are all plausible outcomes for the SDFs trajectory. Understanding what the disasters changed in these four areas is critical in determining the most probable SDF trajectory. This thesis finds that the SDF will not likely embark on a retrenchment or rapid remilitarization trajectory. Japans security and economic interests have not fundamentally changed but rather economic trends in place prior to the disasters were aggravated and its security policy was validated. Japans norms were the most fundamentally changed as the SDF emerged from the disasters as the most trusted institution in Japan. Changes will be limited to the fringes of the status quo bordering remilitarization as numerous disincentives restrain the SDF from rapidly moving toward remilitarization. These changes will come about from a growing sense of economic and security pragmatism that results in engaging rather than containing the SDF. Improved civil-military relations, more public support for the SDFs expanding domestic and international roles, and more deference for the SDF as a useful tool of the state will characterize this new status quo.

L’estimation de position a été l'une des parties les plus cruciales concernant les systèmes de transport intelligents (STI). La localisation précise et fiable en temps réel des véhicules est devenue particulièrement importante pour l'industrie automobile. Les améliorations technologiques significatives en matière de capteurs, de communication et de calcul embarqué au cours des dernières années ont ouvert de nouveaux champs d'applications, tels que les systèmes de sécurité active ou les ADAS, et a aussi apporté la possibilité d'échanger des informations entre les véhicules. Une localisation plus précise et fiable serait un bénéfice pour ces applications. Avec l'émergence récente des capacités de communication sans fil multi-véhicules, les architectures coopératives sont devenues une alternative intéressante pour résoudre le problème de localisation. L'objectif principal de la localisation coopérative est d'exploiter différentes sources d'information provenant de différents véhicules dans une zone de courte portée, afin d'améliorer l'efficacité du système de positionnement, tout en gardant le coût à un niveau raisonnable. Dans cette thèse, nous nous efforçons de proposer des méthodes nouvelles et efficaces pour améliorer les performances de localisation du véhicule en utilisant des approches coopératives. Afin d'atteindre cet objectif, trois nouvelles méthodes de localisation coopérative du véhicule ont été proposées et la performance de ces méthodes a été analysée. Notre première méthode coopérative est une méthode de correspondance cartographique coopérative (CMM, Cooperative Map Matching) qui vise à estimer et à compenser la composante d'erreur commune du positionnement GPS en utilisant une approche coopérative et en exploitant les capacités de communication des véhicules. Ensuite, nous proposons le concept de station de base Dynamique DGPS (DDGPS) et l'utilisons pour générer des corrections de pseudo-distance GPS et les diffuser aux autres véhicules. Enfin, nous présentons une méthode coopérative pour améliorer le positionnement GPS en utilisant à la fois les positions GPS des véhicules et les distances inter-véhiculaires mesurées. Ceci est une méthode de positionnement coopératif décentralisé basé sur une approche bayésienne. La description détaillée des équations et les résultats de simulation de chaque algorithme sont décrits dans les chapitres désignés. En plus de cela, la sensibilité des méthodes aux différents paramètres est également étudiée et discutée. Enfin, les résultats de simulations concernant la méthode CMM ont pu être validés à l’aide de données expérimentales enregistrées par des véhicules d'essai. La simulation et les résultats expérimentaux montrent que l'utilisation des approches coopératives peut augmenter de manière significative la performance des méthodes de positionnement tout en gardant le coût à un montant raisonnable.

Contudo, as indústrias deparam-se com dificuldades em controlar o processo dada a elevada produtividade exigida neste tipo de construções. Este estudo visa estabelecer critérios que permitam aferir a importância da corrente, tempo e pressão no processo de soldadura por resistência por pontos, aplicado ao fabrico de redes electrossoldadas com varões de A500NRSD, através das alterações microestruturais no aço. Caracterizou-se o material base, através de ensaios químicos, mecânicos e metalográficos. Foram realizados ensaios de soldadura em varões de diâmetros de 6 e 8 mm segundo um planeamento composto central circunscrito. Este tipo de planeamento permite analisar a influência de cada variável de processo e suas interacções numa função resposta seleccionada previamente, neste caso foi a força de corte. Observou-se que o parâmetro operatório mais influente depende do diâmetro. Isto é, para o diâmetro de 6 mm o parâmetro mais influente identificado foi a corrente, enquanto para o diâmetro de 8 mm foi o tempo o parâmetro mais relevante. Estudou-se o comportamento estrutural das amostras, fazendo variar o parâmetro mais influente, verificando-se o crescimento da zona de fusão com o aumento do valor da variável de processo. Para compreender a variabilidade do processo, dada pelos valores registados nos ensaios de caracterização mecânica dos varões soldados, analisaram-se para cada diâmetro, as duas amostras que apresentaram maior diferença de força de corte, observando-se uma segunda ZTA no contacto com o eléctrodo, dos provetes que exibiam a força de corte mais elevada. Conclui-se que a variação dos resultados da caracterização mecânica dos pontos pode ser devida á presença de elementos de liga não constantes das normas e a heterogeneidades químicas e estruturais dos varões.

Pełny tekst źródłaThe present work aims to study the reappearance of the phenomenon of the Community Gardens, all over the world and, specifically in the Portuguese context, with special focus on the city of Lisbon. For this purpose, there were selected the Granja’s Social Community Garden and the Campolide and Telheiras’ Recreative Community Gardens, where inquiries were performed with the goal to outline the characterization of the newly-gardeners and to understand the reasons that brought up the return of their interest in the farming activity. It was found that, regardless the typology of the Community Gardens, the reemergence of these spaces is related, not only with the fact that people enjoy practicing agriculture, but also with the growing concern about the quality of the consumed products. Other motivations were considered important, this time directly related with the typology of Community Garden treated. So, while in Granja’s Garden, many gardeners try to remember their rural life through agricultural activity, in Campolide and Telheiras’ Gardens, the proximity with the Nature and the practice of Organic Farming revealed to be determinant aspects. In summary, the reappearance of Community Gardens comes as a revival of past experiences and as a result of the current socioeconomic situation

Pełny tekst źródłaRheumatoid arthritis (RA) is characterized by systemic inflammation, synovitis and the presence of autoantibodies (such as citrullinated proteins and rheumatoid factor). This disease causes joint damage, disability, decreased quality of life, and vascular diseases. The Disease Modifying Anti-rheumatic Drug (DMARDs), such as Methotrexate (MTX), are therapeutic agents that can reduce the symptoms of this disease. The CD8+ T lymphocytes are key effectors cells of the acquired immune response, but their activity must be regulated in order to enable the efficient elimination of pathogens and prevent autoimmune phenomena. In order to understand the role of the CD8+ T cells in RA, we studied the changes in the frequencies of its subpopulations in the peripheral blood (PB) and synovial fluid (SF) of patients with RA (with different disease activity and with or without therapy with MTX), as well as intracellular cytokines released by this population of T cells using the technique of Flow Cytometry (FC). We also studied the changes in serum proinflammatory and anti-inflammatory cytokines by an immunoassay based on an application of the –FC based beads - Cytometric Bead Array (CBAs). In our research work we found significant changes in the CD8CD69+T cells subpopulation (phenotype of activated cells) in patients with RA. We thus conclude that these cells characterize the establishment and activity of RA, and can be assumed as a direct indicator of local inflammation. We thus consider that the analysis of the frequency of this subpopulation in the PB of patients affected with RA could be used as a new way of prognosis. Given that the frequency of the subpopulation of effector memory CD8+T cells (phenotype: CD27+CD62L-CCR7-) has shown a correlation in PB and SF of patients affected with RA, we can conclude that from a screening done in the PB of these patients, we obtain information about the behavior of these cells in the SF. Quantification of cytokines and chemokines from the serum of RA patients came once again demonstrate the importance of these inflammatory mechanisms. On the one hand proteins with proinflammatory action, such as IL-10, and recruitment of polymorphonuclear leukocyte cells of the acute phase, such as MIP-1α, are decreased in RA. On the other hand, chemokines such as MCP-1, MIP-1β, IL-8 and MIG, which although synthesized by different subpopulations have a role in recruiting cells to the inflammatory process and some are also involved in the repair of damaged tissues, are increased in patients with the same pathology. Thus, we conclude that these proteins are important factors in onset and chronicity of the condition. The therapy performed by administering MTX to patients with RA caused changes primarily on the subpopulation of Central Memory (significant increase) and Effector Memory (significant decrease) CD8+ T cells, but also on subset the CD8+T cells that release IL-17 (significant decrease). These results lead us to suggest that one mechanism of action of MTX is by targeting these subsets of CD8+ T cells. We conclude that the several subpopulations of CD8+ T cells that we studied have a significant impact on the establishment and maintenance of this chronic pathology. Therefore in the future we are interested in developing a possible diagnosis for RA based on the information we provided regarding the role of CD8+ Cytotoxic T Lymphocytes (CTLs) in this pathology, as well as a new biological therapies targeting these lymphocytes.

Pełny tekst źródłaIntroduction: Pediatric obesity has become a worldwide public health concern, with a perspective of an even greater increase over the next years, especially among developing countries. Overweight children are exposed from an early age to comorbidities and chronic pathologies that imply on an increase in morbimortality. Concomitantly, the general population, including children, has been sleeping gradatively less time. Studies have been searching for evidence linking sleep deprivation to overweight or obesity. Among pre-school children, this correlation is not well established. Objective: To evaluate the relation between sleep deprivation in the first years of life and overweight or obesity at 4 years of age. Materials and Methods: We used the data from the Pelotas, Brazil, 2004 birth Cohort, corresponding to perinatal, 12, 24 and 48 months follow-ups. On these moments, the child´s main caretaker responded to questions regarding sleep and feeding habits, as well as socioeconomic and demographic characteristics. Children who slept for less than 10 hours per night were considered sleep deprived. Children with a BMI Z-score 2 standard deviations above limits established by the World Health Organization were considered overweight, and those with a BMI Z-score above 3 standard deviations were considered obese. Results: Of the 4263 live births in Pelotas during the study year, 4231 were enrolled in the study. Of those, 94%, 93. 5% and 92% were re-evaluated on the 12, 24 and 48-month follow-ups, respectively. On the analysis stratified by age, only at 24 months we found a positive association between sleep deprivation and overweight at 48 months (PR 1,731. CI95% 1,246; 2,406. P=0,001). Analyzing the relation between sleep deprivation at any moment during the study period, we found that sleep-deprived children had a 27% higher chance of overweight/obesity at the end of the study (RP 1,267. CI 95% 0,989;1,624). This association was maintained after adjusting for possible confounders. Conclusion: On the studied population, children with sleep deprivation between 12 and 48 months of age showed a higher chance of being overweight or obese at 4 years. These findings show the importance of sleep quality and sleep hygiene in prevention and management of overweight and obesity in childhood.
Introdução: A obesidade infantil configura um problema de saúde pública a nível mundial, com uma perspectiva de aumento ainda mais significativo nos próximos anos, especialmente entre países em desenvolvimento. Crianças com sobrepeso são expostas desde muito cedo a comorbidades e patologias crônicas que implicam em aumento da morbimortalidade. Concomitantemente, as horas de sono da população em geral, inclusive crianças, vêm diminuindo de maneira gradativa. Estudos vêm buscando evidencias que conectem a redução do número de horas de sono noturno e obesidade. Entre crianças em idade pré-escolar, tal correlação ainda não está bem estabelecida. Objetivo: Avaliar e associação entre restrição de sono nos primeiros anos de vida e sobrepeso/obesidade aos 4 anos. Materiais e Métodos: Foi utilizado o banco de dados da Coorte de Nascimentos de 2004 da cidade de Pelotas, Brasil, correspondentes aos acompanhamentos perinatal, de 12, 24 e 48 meses. Nesses momentos, o principal cuidador da criança respondeu perguntas a respeito de hábitos de sono, alimentares e sobre características demográficas e socioeconômicas. Consideraram-se restritas em sono as crianças que dormiam em média menos de 10 horas por noite. Consideraram-se com sobrepeso as crianças com escore-Z para IMC a partir de 2 desvios-padrões da média estabelecida pela Organização Mundial de Saúde, e obesos os com a partir de 3 desvios-padrão. Resultados: Dentre os 4. 263 nascidos-vivos daquela cidade, 4. 231 foram inscritos no estudo ainda no período perinatal. Deste total, permaneceram em acompanhamento nos seguimentos de 12, 24 e 48 meses, respectivamente, 94%, 93,5% e 92%. Nas análises por faixa etária, somente aos 24 meses houve associação significativa entre restrição de sono e sobrepeso/obesidade aos 48 meses (PR 1,731. CI95% 1,246; 2,406. P=0,001). Avaliando-se a associação entre restrição de sono em algum momento durante o período acompanhamento e sobrepeso/obesidade aos 48 meses, encontrou-se que os restritos em sono tiveram uma chance 27% maior (RP 1,267. CI 95% 0,989;1,624) de alterações de peso ao final do acompanhamento. Essa associação se manteve após ajuste para potenciais fatores de confusão. Conclusão: Na população estudada, crianças com restrição de sono entre 12 e 48 meses apresentaram maior chance de sobrepeso/obesidade aos 48 meses. Estes achados chamam a atenção para a importância da qualidade do sono e da implantação de higiene do sono na prevenção e manejo de sobrepeso e obesidade na infância.

Pełny tekst źródłaThe search for a method that allows better results for the anastomosis of a completely sectioned nerve has been pursuitted from a long time. From many years the conventional technique using microsurgical sutures has been used to bring near the separated stumps of the injured nerve. Actually, the fibrin glue use is allowing tissue adhesion of the skin, fascia and other anatomical structures. The fibrin glue use for the nervous edges approach, have been propagated by the industries as an incontestable fact. Trying to verify this affirmation an evaluation through the myelin sheath was made along regenerated nerve edges between different techniques of anastomosis of an injured sciatic nerve from Wistar. Was also measured the axon regeneration after this glue application. A 35 rats sample was separated in 03 groups (A, B and C). In group A 25 rats were submitted to nervous anastomosis surgery using fibrin glue. In group B, 05 rats were submitted to the same procedure; however, during nervous repair, two opposite stitches of mononylon 9-0 were added with inward fibrin glue. In group C 05 rats were submitted to neuroraphy with 6-8 stitches of mononylon 9-0 without fibrin glue use (conventional nervous anastomosis). The animals were submitted to a new procedure, 90 days after the initial surgery, to remove and lead to additional study the healed portion of the sciatic nerve. After this procedure the animals were sacrificed. These specimens were submitted to histological preparation and evaluated. The myelin sheath thickness average of the regenerated fibers was measured. The number of regenerated axons by (milimetro quadrado) was also measured. Using these measures a comparison between the results were made.

Pełny tekst źródłaSchool feeding programmes have become a worldwide poverty reduction strategy that are designed to enhance human capital, i.e. nutrition and education. In South Africa, the National School Nutrition Programme (NSNP) began in 1994 and it was designed to enhance learning capacity, to support nutrition education in schools and to promote school gardens. The purpose of this study is to explore whether the expected impacts (nutrition and education) of the NSNP in Cape Town have been achieved. The study used the theory of change as an attempt to explore the expected impacts of the programme and it involved a qualitative research approach. The data was collected using semi-structured interviews. Note-taking and observations of non-verbal behaviour techniques were also used to capture any relevant information. The respondents were 4 school principals, 4 teacher coordinators, 4 food handlers, 4 members of the School Governing Body and one staff member from the Department of Basic Education (DBE) of the Western Cape. Findings from the global literature show that the impacts of school feeding programmes are quite mixed (between nutrition and education). This study has found that the NSNP in Cape Town has improved food security, i.e. reduced short-term hunger (but not necessarily nutrition) and it gave energy to the learners that helped them to actively participate in learning. It also eliminated some negative class behaviours and it functioned as an additional meal to some poor learners. On the education front, it enhanced school attendance, class participation and possibly improved learner performance. However, the programme has also experienced some challenges, i.e. the food quality and quantity, targeting system (the quintile system) that excluded some poor learners from receiving NSNP meals and food gardens were not producing sufficient food because they were small and poorly maintained. This study recommends that rigorous impact evaluation of the NSNP in Cape Town is required in order to address the challenges that were identified as well as to enhance the programme so that it can achieve the desired impacts.
