We introduce a novel technique for neural point cloud consolidation which learns from only the input point cloud. Unlike other point up-sampling methods which analyze shapes via local patches, in this work, we learn from global subsets. We repeatedly self-sample the input point cloud with global subsets that are used to train a deep neural network. Specifically, we define source and target subsets according to the desired consolidation criteria (e.g., generating sharp points or points in sparse regions). The network learns a mapping from source to target subsets, and implicitly learns to consolidate the point cloud. During inference, the network is fed with random subsets of points from the input, which it displaces to synthesize a consolidated point set. We leverage the inductive bias of neural networks to eliminate noise and outliers, a notoriously difficult problem in point cloud consolidation. The shared weights of the network are optimized over the entire shape, learning non-local statistics and exploiting the recurrence of local-scale geometries. Specifically, the network encodes the distribution of the underlying shape surface within a fixed set of local kernels, which results in the best explanation of the underlying shape surface. We demonstrate the ability to consolidate point sets from a variety of shapes, while eliminating outliers and noise.

In this study, we performed one dimensional cylindrical sedimentation tests to investigate the impact of clay mineralogy, ionic concentration, ionic valence on sedimentation, and self-consolidation behavior of clay. The result at 1,000% and 2,000% water content indicates that the water content = 2,000% showed higher self-consolidation coefficient and initial settling velocity, and faster initiation and termination of self-consolidation. Additionally, settling velocity decreased as ionic concentration (0.01 - 2 M) increased, and kaolinite showed higher settling velocity than illite. The observed sedimentation and self-consolidation experimental results implies the need for considering clay mineralogy, water content, ionic concentration, and ionic valence in the geotechnical behavior of high-water content clay sediment.

AbstractFriendship plays a central role in Augustine's thought. It also played a crucial role in structuring the political and social world of the ancient Greeks. Augustine's treatment of friendship, especially in his Confessions, retains some of the terminology that was central to the Greek account, but it simultaneously transforms friendship, and with it the relationship between individual and community. Augustine's formulation of the inner life is reflected in his transformation of friendship, which loses its inherently social character and political dimension even as it sets the stage for the introduction of political thinking based on the primacy of the individual.

Based on the axisymmetric large-strain consolidation (ALSC) model with the void ratio as the variable under equal strain condition, difference schemes of model’s equation, initial condition, and boundary condition were given. Taking phosphatic clay in Florida as a research object, the consolidation behaviors of soil with high water content by axisymmetric large-strain theory and one-dimensional large-strain theory were analyzed. The effect of different kinds of consolidation theories and self-weight stress on an average degree of consolidation was evaluated. The development of the void ratio and excess pore water pressure along the soil layer was clarified. The results show that the theoretical value of Terzaghi’s consolidation degree is always less than that of ALSC (Us, the average degree of consolidation defined by strain)-vertical drainage in the consolidation process. Terzaghi’s solution overestimates the dissipation rate of excess pore water pressure during the earlier consolidation period but underestimates it during the later consolidation period. The degree of consolidation calculated by Hansbo develops faster than ALSC (Up, the average degree of consolidation defined by stress)-radial drainage, but slower than ALSC (Us)-radial drainage. In the ALSC model, Us is always been faster than Up. The effect of self-weight on the consolidation degree of axisymmetric large-strain consolidation theory is relatively small (maximum error is less than 16%), while it can accelerate the consolidation rate of soil in one-dimensional large-strain consolidation theory largely. When only the vertical drainage occurs, the consolidation rate in the middle of the soil is obviously lagging the upper and lower parts, while the radial drainage can reduce the void ratio and the excess pore water pressure along the soil layer uniformly and more rapidly.

This study was guided by two principal goals. First, the intent of the researcher was to contribute substantively to the theoretical literature on the study of resilience. Next, an intervention program based on these theoretical contributions was developed, implemented, and evaluated to gauge the relevance of emerging understandings for clinical practice. To conduct this line of inquiry, and in the hope of helping those at risk, the intellectual context of life span developmental psychology, in which all further comments have been grounded, is framed. Next, an understanding of what is meant by resilience and its related constructs is conveyed. Following, the concept of self-understanding is discussed as a potential mediating or protective factor in the service of resilience. The case has been made for conceptualizing the processes of resilience and the role of self-understanding as part of the more basic and universal human drive to create meaning. Following this discussion, a plan of inquiry is described that focuses on an intervention designed to enhance self-understanding among a population of adolescents in the service of resilience. In particular, within the context of a comprehensive developmental counseling program consultation, a psychoeducational group intervention targeting adolescents facing a significant educational transition was the focus of this descriptive study. Findings indicate that over the time period during which the group intervention was implemented, student participants tended to show similarly improved scores on the Self-Perception Inventory, resulting in similar growth trajectories. While none of the fixed predictors (e.g., gender, ethnicity, or scholarship/nonscholarship) accounted in a statistically significant way for the variation observed, initial status was shown to be a statistically significant predictor. These findings suggest that further research may be warranted to explore the efficacy of the overall developmental counseling program as well as the specific intervention that was the focus of the study. In the concluding discussion, original theoretical contributions have been reevaluated, and recommendations for further study, including empirical, descriptive, and theoretical efforts, are put forth.

Channeling has already been an observed phenomenon that often occurs during settling and sedimentation processes of finer materials. However, it has been regarded as a minor factor affecting settling process, e.g. settling velocity or consolidation rate. In this study, settling behaviors of talcs, kaolins and attapulgite were reviewed by experiments with small and large settling columns with special focus on channel formation during sedimentation. The large settling column is equipped with twenty eight measuring points, which are connected to pressure transducers for measuring pore pressure changes during settling. Throughout the study, channel formation was observed and related to the experimental conditions affecting it. The excess pore pressure changes were measured during the large column tests. Channels occurred under flocculation in zone settling and also in consolidation zones; pressure drop was observed near channels in some cases. It was apparent that channels work as a facilitator to dissipate the excess pore water pressure. It is summarized that not only initial concentration but also the material properties, such as specific gravity and shape of particles, can affect the channel formation.

Résumé : Ce projet de recherche s’inscrit dans le cadre d’une requête de l’entreprise partenaire, Golder Associés Ltée. Cette dernière s’interrogeait sur la consolidation d’un résidu minier épaissi, une approche de plus en plus utilisée dans le domaine de la gestion des aires de déposition des résidus miniers. Ce type de matériau est épaissi jusqu’à un point où une fois déposé, il ne connaît pas ou peu de ségrégation, rejette moins d’eau et possède généralement un angle de repos plus grand que les résidus conventionnels. L’intérêt de cette approche dans le cadre de cette étude consiste en la réduction des empreintes des aires de déposition par la combinaison des résidus épaissis et des rehaussements par l’amont. La consolidation de ce type de résidus a été peu étudiée depuis leur développement. En rassemblant les observations rapportées dans les écrits scientifiques, il est possible de ressortir que le mécanisme physique générant la dissipation des pressions interstitielles en excès et le tassement au moment de la déposition est essentiellement la consolidation sous le poids propre. Un essai en colonne de tassement instrumentée de transmetteurs de pression a permis l’étude de la consolidation sous le poids propre en termes de dissipation des pressions d’eau avec une grande précision. Un essai en consolidomètre a permis de définir la compressibilité du matériau durant cette étape de consolidation sous le poids propre avec une précision acceptable. Les résultats expérimentaux ont été reproduits à l’aide du modèle CS2 suite à quelques ajustements des relations constitutives. CS2 considère la consolidation sous le poids propre et les grandes déformations d’une déposition instantanée. Le rapprochement entre le modèle CS2 et les résultats expérimentaux est sans équivoque et permet de prendre connaissance de certains aspects de la consolidation sous le poids propre qui étaient peu détaillés jusqu'à maintenant dans les écrits scientifiques. L’importance de la consolidation sous le poids propre et son intégration dans le plan de déposition proposé par l’entreprise partenaire a été évaluée à l’aide du logiciel SIGMA/W. Les capacités de ce logiciel ont tout d’abord été étudiées en 1D. Ces vérifications visaient la considération de la consolidation sous le poids propre tout en examinant la formulation de SIGMA/W pour un remplissage progressif. Ces simulations 1D ont pu être comparées aux résultats du modèle CS4, un modèle calqué sur CS2 qui permet un remplissage progressif. Finalement, une campagne de simulation à grande échelle en 2D visant la simulation d’une aire de déposition de résidus épaissis a permis d’examiner les éléments importants dans la considération de ce mécanisme à l’aide du logiciel commercial SIGMA/W. Il en ressort que le logiciel SIGMA/W n’est pas le logiciel idéal pour simuler la déposition progressive de résidus épaissis en considérant la consolidation sous le poids propre et ce pour maintes raisons. Les résultats de cette étude viennent situer l’importance de la consolidation sous le poids propre dans les résidus épaissis et fournissent une base solide pour la compréhension et la modélisation numérique de ce mécanisme en 1D ou en 2D. // Abstract : This research project was done through an academic partnership between the Université de Sherbrooke and Golder Associés Ltée., a mining consultant from Montréal. The latter had interrogations at regarding consolidation mechanisms controlling thickened tailings deposition, a relatively new approach in tailings management. This type of material are thickened to a point from which they don’t show any segregation, they expulse less water and can be stacked with a greater beach angle than conventional tailings. The combination of this method with the upstream raising method results in the possible reduction of the footprint of the tailings disposal facility. Thickened tailings have not been studied extensively. However, by gathering available information from the existing technical literature, it is apparent that the sole mechanism creating both a dissipation of excess pore water pressure and a settlement following deposition is self-weight consolidation. A settling column monitored with pressure transmitters was used to define accurately the self-weight consolidation process in terms of dissipation of excess pore water pressure. A consolidometer setup was used to define the compressibility of this material during the self-weight consolidation. Experimental results were reproduced with the numerical model CS2 which considers the self-weight consolidation and large strains. Following a few adjustments of the constitutive relationships, the numerical reproduction is clear; it represents closely the experimental results. This made it possible to document certain elements that were not well defined in the technical literature about the self-weight consolidation. The use of the finite element model SIGMA/W and its capability to consider self-weight consolidation within a tailings deposition scheme were evaluated. Firstly, the model capabilities were verified through 1D simulations that helped to document the method to adopt to model the self-weight consolidation. The formulation of SIGMA/W related to the sequential tailings placement was also studied during this phase. A comparison with the model CS4 was also performed. Secondly, the tailings disposal facility was modeled at large scale by including the sequential tailings placement and the consideration of the self-weight consolidation for each deposition. This process allowed evaluating the capabilities of SIGMA/W in large scale analysis. It appears that this numerical tool presents some numerical weaknesses especially with regards to the sequential tailings placement. Moreover, the results of this study place the self-weight consolidation of hard rock thickened mine tailings as an important mechanism that needs to be considered in a deposition scheme as it controls the short term displacements of the impoundment. Finally, they document the self-weight consolidation mechanism and provide reliable information for modelling this process in one or two-dimensional numerical analysis.

A presente tese de doutorado tem por objetivo analisar criticamente a construção pelo Supremo Tribunal Federal de significados para o direito ao silêncio – ou melhor, a garantia de vedação de auto-incriminação – que constitui uma garantia processual penal de assento constitucional. Foram identificados e analisados todos os acórdãos proferidos pelo Supremo Tribunal Federal acerca do tema a fim de examinar os argumentos utilizados na fundamentação das decisões que delimitam o conteúdo da referida garantia,, desde a promulgação da Constituição de 1988 até o dia 31 de dezembro de 2007, para identificar como o Supremo Tribunal Federal construiu um significado que fosse aquém ou além da simples interpretação gramatical da Constituição. A escolha da vedação de autoincriminação como objeto de estudo é resultado do reconhecimento de que essa garantia desempenha um papel estruturante na construção de um sistema punitivo compatível com um Estado democrático de direito. O exame dos julgados indica que esse conteúdo foi construído por meio de diferentes recursos, como o uso de precedentes jurisprudenciais de cortes internacionais e a interpretação a partir dos tratados internacionais de direitos humanos. Mas, sobretudo, o Supremo Tribunal Federal lançou mão do uso de argumentos principiológicos como forma de aproximar o texto constitucional (e o infraconstitucional) dos valores que animam um Estado democrático de direito.
This doctoral thesis aims to examine and criticize the construction by the Brazilian Supreme Court (Supremo Tribunal Federal, STF) of a concept to the right to silence – or rather, the privilege against self-incrimination – which is a criminal procedure guarantee, established in the Brazilian Constitution. All judgments of the Brazilian Supreme Court related to the privilege, since the promulgation of the Constitution (October 5, 1988) until December 31, 2007, were identified and analyzed, seeking to identify in what form the Brazilian Supreme Court defined that privilege (behind or beyond simply grammatical interpretation of the Constitution). Choosing the privilege against selfincrimination as the object of study results of the recognition that this right plays a structural role in the construction of a punitive system compatible with a democratic rule of law. Examination of all cases indicates that the privilege content was built through various resources, such as international courts decisions and international human rights treaties. But above all, the Brazilian Supreme Court has used principles arguments as a way to bring the constitutional text closer to the values that animate a democratic rule of law.

Establishing healthy sleep-wake patterns early in infancy is vitally important as sleep problems can persist. Behavioural sleep interventions such as the parental presence procedure are well established and have been found to improve infant sleep as determined by parent report. The exact nature of this improvement is, however, unclear. Sleep consolidation, sleep-state organisation, and self-soothing are thought likely to change after intervention; however, no known research has comprehensively determined which of these variables change as infant sleep changes in response to intervention. Three participants aged between 7 to 11 months who met the criteria for Infant Sleep Disturbance (ISD) were referred by a Health Centre and the parental presence behavioural sleep intervention was implemented. Parental report and videosomonography (VSG) data were used to measure sleep before and after intervention. While parental report is limited in that parents can only report what they can hear and/or see, VSG offers a tool that can be used to measure sleep-state organisation, state changes, and periods when the infant is awake and quiet. The present research found that infants’ sleep became more consolidated resulting in fewer sleep-wake transitions and night wakings. Infants who had difficulties initiating sleep on their own also demonstrated decrease in Sleep Onset Delay (SOD). Furthermore, infants were found to sleep through a greater number of sleep-state transitions and sleep for a greater duration of time before waking. Collectively this research provides some evidence that changing parental behaviours to those that promote self-initiation through self-soothing and consistency, can change sleep-state organisation and improve self-soothing.

Abstract: The use of self-consolidating concrete (SCC) in the concrete industry in cast-in-place applications, including repair applications, is growing given the various advantages offered in both fresh and hardened states. The present study deals with the design and performance of fiber-reinforced self-consolidating concrete (FR-SCC) as a repair material of concrete infrastructure. The study also considers the use of various steel and synthetic fibers (five fibers in total) that were used to produce FR-SCC and fiber-reinforced self-consolidating mortar (FR-SCM) that can be employed for structural and non-structural repair applications. The study evaluates the effect of material properties and mixture composition of the fibrous concrete and mortar on workability, mechanical, visco-elastic, durability, and structural behavior. The investigation that is presented in this thesis included the testing of 28 full-scale beams under four-point flexural loading. The majority of these beams were repaired by casting concrete to fill a relatively thin section along the tension zone of the beams. The repair technique was based on the FR-SCC characteristics including the maximum fiber volume and length. This technique required mixtures of high range of fluidity. The optimized FR-SCC and FR-SCM mixtures exhibited excellent flow characteristics along the 3.2-m long beams without blockage, segregation, nor debonding at the interface of repair-substrate concrete. Based on the structural characteristics of the composite beams, the overall performance of the beams repaired using the FR-SCC and FR-SCM was similar or higher (up to 2.6 times) than that of monolithic beams made with conventional vibrated concrete (CVC). The use of optimized FRSCC mixtures enabled the replacement of 50% of the tension steel reinforcement in repair sections; i.e., the number of bars in the tension zone decreased from three bars to two bars with the addition of fibers in the SCC without mitigating structural performance. The degree of prediction of crack width, cracking load/moment, ultimate loads, and deflection of various FR-SCC and FR-SCM mixture was evaluated using several design and code models. The results indicate that these code models can provide safe predictions for crack and ultimate loads, as well as crack width of FR-SCC. The deflection of FR-SCC is unsafe but predictable by these code models. In total, 18 large-scale beams were tested in four-point for flexural creep. FR-SCC incorporating steel fibers combined with expansive agent provided overall performance up to 10 times of that obtained with CVC with the same fiber type and volume. The cracking under constant load was reduced by 60% to 80% using self-consolidating fibrous mixtures made with or without expansion agents, compared to SCC without fibers. The best combination to reduce the cracking potential when the restrained shrinkage ring test was employed was obtained with SCC mixtures made with steel fibers and expansive agent. Models were elaborated to predict the time-to-cracking for FR-SCC and FR-SCM mixtures based on mixture modulus of elasticity and drying and autogenous shrinkages. The project involved extensive testing of highly flowable fibrous materials to determine drying shrinkage (nearly 260 prisms), modulus of rupture (nearly 180 prisms), as well as compressive and splitting tensile strengths and elastic modulus (nearly 2100 cylinders). Based on the results, models were proposed to predict these key material properties that affect the performance of FR-SCC and FR-SCM used in repair applications. In addition to FR-SCC, the investigation also was set to evaluate the feasibility of using fiber-reinforced superworkable concrete (FR-SWC) in construction and repair applications. Such highly flowable concrete that requires limited vibration consolidation can represent some advantages over FR-SCC (lower admixtures demand, lower risk of segregation, greater robustness, lower formwork pressure, etc.). The energy needed to ensure proper consolidation, using either vibration or rodding, applied on samples made with FR-SWC was determined. The energy requirement took into consideration the development of mechanical properties, the resistance to segregation, and the development of proper surface quality. The study also demonstrated the higher overall structural performance of optimized FR-SWC compared to the corresponding FR-SCC mixtures. The findings of the thesis on the design and performance of highly workable fiber-reinforced cementitious materials should facilitate the acceptance of such novel high-performance material in infrastructure construction and repair applications. // Résumé: L'utilisation du béton autoplaçant (BAP) dans l'industrie du béton dans les applications du coulage sur place incluant les applications de la réparation, est en croissance vu les divers avantages offerts à l'état frais et à l'état durci. La présente étude traite de la conception et la performance des bétons autoplaçants fibrés (BAPF) en tant que matériau de réparation des infrastructures en béton. L'étude considère également l'usage de différentes fibres métalliques et synthétiques (cinq fibres au total) qui ont été utilisées pour produire des BAPF et des mortiers autoplaçants fibrés (MAPF) pour des applications de réparations structurales et non structurales. L'étude évalue l'effet des propriétés du matériau et la composition des bétons et mortiers fibrés sur l'ouvrabilité, les propriétés mécaniques, viscoélastiques, de durabilité et le comportement structural. L'étude présentée dans cette thèse a inclus 28 poutres à grande échelle testées sous un chargement flexionnel à quatre points. La majorité de ces poutres a été réparée par le coulage du béton pour remplir une section relativement mince tout au long de la zone tendue des poutres. La technique de réparation a été basée sur les caractéristiques des BAPF incluant le volume maximal et la longueur maximale de fibres. Cette technique a requis des mélanges de haut niveau de fluidité. Les BAPF et MAPF ont exhibé d'excellentes caractéristiques d'écoulement le long de 3,2 m, la longueur de la poutre, sans blocage, ségrégation, ni décollement à l'interface entre le béton de base et le béton de réparation. En se basant sur les caractéristiques structurales des poutres composites, la performance globale des poutres réparées en utilisant les BAPF et les MAPF était similaire ou supérieure (jusqu'à 2,6 fois) que celle des poutres monolithiques fabriquées d'un béton conventionnel vibré (BCV). L'utilisation des mélanges de BAPF optimisés a permis de remplacer 50% du ferraillage tendu dans les sections de réparation; c'est-à-dire que le nombre des barres d'armatures dans la zone tendue a réduit de trois barres à deux barres avec l'addition de fibres dans le BAP sans mitiger la performance structurale. Le degré de prédiction de la largeur de fissures, charge de fissuration, charge ultime et déflexion de différents mélanges de BAPF et MAPF a été évalué en utilisant quelques designs et modèles de codes. Les résultats ont montré que ces modèles ont pu fournir de prédictions sécuritaires pour les charges de fissuration et ultime, ainsi que la fissuration des BAPF. La déflexion des BAPF est non sécuritaire mais reste prédictible par ces modèles de codes. En total, 18 poutres à grande échelle ont été testées en fluage flexionnel de quatre points. Des BAPF contenant des fibres métalliques combinées avec un agent expansif ont fourni une performance globale jusqu'à 10 fois celle obtenue avec un BCV contenant le même type et volume de fibres. La fissuration sous une charge constante a été réduite de 60% à 80% en utilisant des mélanges autoplaçants fibrés fabriqués avec ou sans agents expansifs, par rapport au BAP sans fibres. La meilleure combinaison pour réduire le potentiel de fissuration avec l'essai du retrait restreint a été obtenue avec des mélanges de BAP contenant de fibres d'acier et un agent expansif. Des modèles ont été élaborés pour prédire le temps de fissuration des mélanges de BAPF et MAPF basés sur le module d'élasticité du mélange et les retraits de séchage et endogène. Le projet comportait de nombreux essais sur les mélanges fibrés de haute fluidité à savoir la détermination du retrait de séchage (près de 260 prismes), le module de rupture (près de 180 prismes), ainsi que la résistance en compression, la résistance en traction et le module d'élasticité (plus de 2100 cylindres). En se basant sur les résultats, des modèles ont été proposés pour prédire ces propriétés clés qui affectent la performance des BAPF et MAPF destinés aux applications de réparation. En plus des BAPF, l'étude a aussi été faite pour évaluer la faisabilité de l'utilisation des bétons semi-fluides fibrés (BSFF) dans les applications de construction et de réparation. Tels bétons de haute fluidité requérant une consolidation limitée peuvent présenter certains avantages par rapport aux BAPF (plus faible demande en adjuvants, plus faible risque de ségrégation, robustesse supérieure, plus faible pression sur les coffrages, etc.). L'énergie nécessaire pour assurer une propre consolidation, en utilisant soit la vibration ou le piquage, appliquée sur des échantillons de BSFF a été déterminée. Les exigences de cette énergie considèrent le développement des propriétés mécaniques, la résistance à la ségrégation et la propre qualité de surface. L'étude a aussi démontré une performance structurale globale supérieure des BSFF optimisés par rapport aux mélanges de BAPF correspondant. Les conclusions de la thèse sur le design et la performance des matériaux cimentaires renforcés de fibres et de haute fluidité devraient faciliter l'acceptation de tels nouveaux matériaux de haute performance dans les applications de la construction et la réparation des infrastructures.

The field of machine learning currently draws massive attention due to ad- vancements and successful applications announced in the last few years. One of these applications is self-driving vehicles. A machine learning model can learn to drive through behavior cloning. Behavior cloning uses an expert’s behavioral traces as training data. However, the model’s steering predictions influence the succeeding input to the model and thus the model’s input data will vary depending on earlier predictions. Eventually the vehicle may de- viate from the expert’s behavioral traces and fail due to encountering data it has not been trained on. This is the problem of sequential predictions. DAG- GER and its improvement SafeDAGGER are algorithms that enable training models in the sequential prediction domain. Both algorithms iteratively col- lect new data, aggregate new and old data and retrain models on all data to avoid catastrophically forgetting previous knowledge. The aggregation of data leads to problems with increasing model training times, memory requirements and requires that previous data is maintained forever. This thesis’s purpose is investigate whether or not SafeDAGGER can be improved with continual learning to create a more scalable and flexible algorithm. This thesis presents an improved algorithm called EWC-SD that uses the continual learning algo- rithm EWC to protect a model’s previous knowledge and thereby only train on new data. Training only on new data allows EWC-SD to have lower training times, memory requirements and avoid storing old data forever compared to the original SafeDAGGER. The different algorithms are evaluated in the con- text of self-driving vehicles on three tracks in the VBS3 simulator. The results show EWC-SD when trained on new data only does not reach the performance of SafeDAGGER. Adding a rehearsal buffer containing only 23 training exam- ples to EWC-SD allows it to outperform SafeDAGGER by reaching the same performance in half as many iterations. The conclusion is that EWC-SD with rehearsal solves the problems of increasing model training times, memory re- quirements and requiring access to all previous data imposed by data aggre- gation.
Fältet för maskininlärning drar för närvarande massiv uppmärksamhet på grund av framsteg och framgångsrika applikationer som meddelats under de senaste åren. En av dessa applikationer är självkörande fordon. En maskininlärningsmodell kan lära sig att köra ett fordon genom beteendekloning. Beteendekloning använder en experts beteendespår som träningsdata. En modells styrförutsägelser påverkar emellertid efterföljande indata till modellen och således varierar modellens indata utifrån tidigare förutsägelser. Så småningom kan fordonet avvika från expertens beteendespår och misslyckas på grund av att modellen stöter på indata som den inte har tränats på. Det här är problemet med sekventiella förutsägelser. DAGGER och dess förbättring SafeDAGGER är algoritmer som möjliggör att träna modeller i domänen sekventiella förutsägelser. Båda algoritmerna samlar iterativt nya data, aggregerar nya och gamla data och tränar om modeller på alla data för att undvika att katastrofalt glömma tidigare kunskaper. Aggregeringen av data leder till problem med ökande träningstider, ökande minneskrav och kräver att man behåller åtkomst till all tidigare data för alltid. Avhandlingens syfte är att undersöka om SafeDAGGER kan förbättras med stegvis inlärning för att skapa en mer skalbar och flexibel algoritm. Avhandlingen presenterar en förbättrad algoritm som heter EWC-SD, som använder stegvis inlärningsalgoritmen EWC för att skydda en modells tidigare kunskaper och därigenom enbart träna på nya data. Att endast träna på nya data gör det möjligt för EWC-SD att ha lägre träningstider, ökande minneskrav och undvika att lagra gamla data för evigt jämfört med den ursprungliga SafeDAGGER. De olika algoritmerna utvärderas i kontexten självkörande fordon på tre banor i VBS3-simulatorn. Resultaten visar att EWC-SD tränad enbart på nya data inte uppnår prestanda likvärdig SafeDAGGER. Ifall en lägger till en repeteringsbuffert som innehåller enbart 23 träningsexemplar till EWC-SD kan den överträffa SafeDAGGER genom att uppnå likvärdig prestanda i hälften så många iterationer. Slutsatsen är att EWC-SD med repeteringsbuffert löser problemen med ökande träningstider, ökande minneskrav samt kravet att alla tidigare data ständigt är tillgängliga som påtvingas av dataaggregering.

Les technologies de placement de plis ou d’enroulement filamentaire de composite à matrice thermoplastique avec consolidation en continu ont fait l’objet de nombreux travaux ces dernières années. Ces études ont porté principalement sur des composites à base de matrice thermoplastique semi-cristalline comme le poly(éther éther cétone) (PEEK) renforcée de fibres de carbone. L’objectif de la thèse est de déterminer les lois de comportement du composite fibres de carbone/matrice thermoplastique lors de la mise en œuvre afin de déduire quelle étape gouverne le processus de soudage et quels sont les paramètres procédés et matériaux influençant sa durée. Dans ce but, les principales propriétés de la matrice utiles à l’étude ont, dans un premier temps, été déterminées. Une attention particulière a été portée sur la dégradation thermique. Les analyses en thermogravimétrie ont ainsi permis d’évaluer sa cinétique de dégradation. Dans un deuxième temps, les mécanismes de contact intime et d’autohésion, responsables du soudage, ont été étudiés à partir de modèles. Pour cela, les mesures de rugosité de surface et de viscosité ont été intégrées au modèle de contact intime. Le temps de diffusion de la matrice a été déterminé par rhéologie puis intégré au modèle d’autohésion. Enfin, l’influence des paramètres procédé (temps, température et pression) et matériau (masses molaires et rugosité) sur les mécanismes de formation de l’interface et ses performances mécaniques a été évaluée expérimentalement par des tests d’adhérence (clivage et pelage) et comparée aux modèles
The automated tow placement or filament winding processes of thermoplastic-based composites have been intensively studied in recent years. These studies concerned mainly composites with thermoplastic semi-crystalline matrices as carbon fiber reinforced poly(ether ether ketone) (PEEK). The thesis objective is to understand the physical mechanisms taking place in a thermoplastic-based composite during the welding in order to deduce which step governs the welding process and what are the parameters influencing its duration. First, the main properties of matrix of interest for this study were determined, in particular its thermal degradation. The thermal gravimetric analysis thus allowed to evaluate the kinetics of degradation. Secondly, the mechanisms of intimate contact and self-adhesion responsible for welding were studied using models. For this, surface roughness and viscosity measurements were included in the model of intimate contact. The diffusion time of matrix was determined by rheology and integrated into the self-adhesion model. Eventually, the influence of process (time, temperature and pressure) and material (molecular weight and roughness) parameters on the mechanisms of interface formation and its mechanical performance was evaluated experimentally by adhesion tests (wedge test and peeling ) and compared with models

Large-scale virtualized data centers require cloud providers to implement scalable, autonomic, and energy-efficient cloud management systems. To address these challenges this thesis provides four main contributions. The first one proposes Snooze, a novel Infrastructure-as-a-Service (IaaS) cloud management system, which is designed to scale across many thousands of servers and virtual machines (VMs) while being easy to configure, highly available, and energy efficient. For scalability, Snooze performs distributed VM management based on a hierarchical architecture. To support ease of configuration and high availability Snooze implements self-configuring and self-healing features. Finally, for energy efficiency, Snooze integrates a holistic energy management approach via VM resource (i.e. CPU, memory, network) utilization monitoring, underload/overload detection and mitigation, VM consolidation (by implementing a modified version of the Sercon algorithm), and power management to transition idle servers into a power saving mode. A highly modular Snooze prototype was developed and extensively evaluated on the Grid'5000 testbed using realistic applications. Results show that: (i) distributed VM management does not impact submission time; (ii) fault tolerance mechanisms do not impact application performance and (iii) the system scales well with an increasing number of resources thus making it suitable for managing large-scale data centers. We also show that the system is able to dynamically scale the data center energy consumption with its utilization thus allowing it to conserve substantial power amounts with only limited impact on application performance. Snooze is an open-source software under the GPLv2 license. The second contribution is a novel VM placement algorithm based on the Ant Colony Optimization (ACO) meta-heuristic. ACO is interesting for VM placement due to its polynomial worst-case time complexity, close to optimal solutions and ease of parallelization. Simulation results show that while the scalability of the current algorithm implementation is limited to a smaller number of servers and VMs, the algorithm outperforms the evaluated First-Fit Decreasing greedy approach in terms of the number of required servers and computes close to optimal solutions. In order to enable scalable VM consolidation, this thesis makes two further contributions: (i) an ACO-based consolidation algorithm; (ii) a fully decentralized consolidation system based on an unstructured peer-to-peer network. The key idea is to apply consolidation only in small, randomly formed neighbourhoods of servers. We evaluated our approach by emulation on the Grid'5000 testbed using two state-of-the-art consolidation algorithms (i.e. Sercon and V-MAN) and our ACO-based consolidation algorithm. Results show our system to be scalable as well as to achieve a data center utilization close to the one obtained by executing a centralized consolidation algorithm.

This article investigates the historical formation and specific configuration of a threefold relation crucial to contemporary society, that between the body, the self, and material culture, which, in contemporary, late modern (or post-industrial) societies, has become largely defined through consumer culture. Drawing on historiography, sociology, and anthropology, it explores how, from the early modern period, the consolidation of new consumption patterns and values has given way to particular visions of the human being as a consumer, and how, in turn, the consumer has become a cultural battlefield for the management of body and self. The article also discusses tastes, habitus, and individualization.

Addiction liability involves multiple aspects of the person and the context. The within-person aspects can be organized within a broad temperament framework involving constituents of self-regulation. A fundamental dual-process model helps organize and structure the research program because self-regulation is conceived as involving both bottom-up and top-down capacities. From this perspective, addiction liability emerges and expresses itself in relation to early consolidation of bottom-up appetitive systems, organization of top-down control and executive processes, and progressive assembly of either self-regulation or its disruption in dysregulatory psychopathology such as attention-deficit/hyperactivity disorder and conduct problems. Several key studies supporting this hierarchical and sequential emergence of liability and addiction risk are summarized in this chapter.

The guidance experience, pedagogically considered, is above all the process of identification, recognition and consolidation of individual resources of which the person is the bearer (attitudes, capabilities, inclinations, expectations, desires, projects), is the conquest of one’s own identity, the research of constituent elements of personality, the awareness of ‘being-different-from-everyone-else’. Within this theoretical assumption, the narration is a suitable placement as estimable and relevant device for self-guidance and transformation of the self. In the guidance actions the use of narrative, reflective and autobiographical paradigms can represent an effective aid in the direction of the redefinition of identity, empowerment and self-empowerment. Narration is the search for the truth about the self, or even more the process of re-thinking and re-design the self. It means to discover and achieve a deep knowledge about the self, to reconstruct one’s own life plan, is to de-form to re-emerge, to re-form it. In a broad sense, it is in some way to ‘die’ to be reborn regenerated

By in situ tests, the impaction of the marine hydrodynamics, such as wave and tide, on the rapidly deposited sediments consolidation process was studied. In the tide flat of Diaokou delta-lobe, one 2m×1m×1m test pit was excavated. The fluid sediments imitating the rapidly deposited seabed silts were made in-situ, and an iron plate covered part of the test pit to cut off the effect of the marine hydrodynamics. By field-testing methods, like static cone penetration test, the variation of strength is measured at real time, and the marine hydrodynamics’ impaction on the consolidation process of the sediments in the Yellow River Estuary was studied. It is shown that the self-consolidated sediments’ strength linear increased with the depth. In the consolidation process, in the initial, marine hydrodynamics play a decisive role, about three times as much as self-consolidated in raising the strength of the sea-bed soils, and with the extension of the depth the role of the hydrodynamics reduced. With the continuation of the consolidation process, the trend of the surface sediments’ increased-strength gradually slowed under the water dynamics, while the sediments below 30cm was in opposite ways. As a result, the rapidly deposited silts present a nonuniform consolidation state, and the crust gradually formed. The results have reference in studying the role of the hydrodynamics in the soil consolidation process.

Consolidation is one of the most important processes that are needed to be accounted for in the model of cohesive sediment transport. Previous studies have shown that the consolidation paths for soil elements are not unique at low effective stress (here low effective stress means the effective stress is smaller than a threshold effective stress, which is short as TES and denoted as σb) In this study, a new theoretical constitutive equation for the effective stress of soft mud is derived to describe the non-unique consolidation paths at low effective stress. Firstly, based on the concept of fractal dimension, the mud flocs are treated as self-similar fractal entities and the relationship between mud floc size and sediment volume fraction is established. Due to the fact that the fractal dimension decreases as the floc size increases, the variation of fractal dimension is accounted for. Based on the self-similar model, the theoretical constitutive equation for the effective stress of soft mud is derived. The constitutive equation is validated using two data sets obtained from consolidation tests in a settling column for soft clay. At low effective stress, the model results curves follow the data trends and the non-uniqueness of consolidation paths are captured. The model results are also compared with existing numerical results and better agreement is presented especially when η is less than 0.5.

In accordance with the cost-saving campaign in Mahakam block, sand consolidation was successfully developed as a cheaper alternative to sand control. Despite the limited development of sand consolidation market and the successful application of sand consolidation products from the current incumbent, Company faces the risk of limited access to other products and potential failure to switch existing products. However, self-validation for any desired product with lower risk exposure is considerable. Taking all the necessary lessons learned during initial product development, the successful application of sand consolidation depends on proper control of product deployment rather than the product composition itself. The systematic arrangement of all controlled parameters generates a causal relationship, which will act as a validating workflow to the other 3 new products. During the deployment of these products in 17 wells, all parameters were successfully controlled and it was possible to make the wells producing with a success rate of more than 90%. Based on this study result, Company will have more flexibility in using sand consolidation products variation by considering the associated resources: attractive pricing, contractual fairness, and logistic access.

Abstract Because of their low density, high specific strength, and high stiffness, titanium alloys are one of the prime candidates for structural application often requiring specific tribological properties. However, their relatively high friction coefficients and low wear resistance are limiting their application over a wider range of temperature. Various coating technologies are currently available to enhnace the surface by improving wear and friction characteristics. While the most widely used methods (High-Velocity Oxy-Flame (HVOF), Detonation-Gun (D-Gun), Electron-Beam Physical Vapor Depostion (EB-PVD), etc.) can improve wear performance and decrease corrosion damage, the required higher temperatures usually preclude the integration of thermally vulnerable lubricants. In this research, a low temperature, High-Velocity-Particle Consolidation process (HVPC) was investigated for coating Ti-6Al-4V due to its various advantages over conventional thermal spray processes. The optimum feedstock (nickel + solid-lube) for self-lubricating coating has been developed and compared with respect to different particle sizes and particulate composites. The coating characteristics and its microstructural homogeneity were assessed at various operating parameters and feedstock compositions.

Orchestrated irrationality in our public discourse is produced by technologically enhanced and commercially purposed atomization and tribalism. Public discourse now leans away from a humane, free, and reasoned political rationality and towards self-interested, calculative, herd conformism. The bulls and bears of consumer society have largely displaced the civic logic of the liberal democratic pursuit of the common good. The power interests that govern global consumerism are enhanced by subordinating the common good ends of genuinely political life to the self-interested and profit driven dynamics of the market. Orchestrated irrationality in our public discourse makes politics into a meaningless theatre of incommensurate tribal interest narratives, which is a convenient distraction from the collaborative consolidation of market power and state control. This orchestrated irrationality can only be combatted by seeking to de-atomize citizens and de-tribalize the public square in order to recover the priority of political life over market and authoritarian power in our public discourse. That is, a postcapitalist civilization that is oriented to a genuinely political and universally moral rationality must replace the present global order. Once we can identify the problem and the direction of cure for orchestrated irrationality, we can then take steps towards a different civilizational life-world.

In an effort to identify alternative and beneficial use placement strategies for dredged sediments from the Atlantic Intracoastal Waterway (AIWW), the US Army Corps of Engineers, Savannah District (SAS), and the US Army Engineer Research and Development Center (ERDC) performed a series of physical property tests of 34 core borings from the SAS AIWW. Physical property testing found that 14 of the borings were non-cohesive sandy materials that may be suitable for potential beach renourishment or berm construction. The remaining 20 borings had mud contents sufficient enough to result in cohesive behavior. A subset of six of these materials from across the geographic region were further evaluated to characterize their erosion behavior. Following a self-weight consolidation period of 30 days, erosion testing showed that the tested cohesive sediments had critical shear stress values that ranged from 1.7 Pa to 2.9 Pa, suggesting that these sediments would likely be resistant to erosion in most wetland environments after placement. Additionally, the cohesive sediments were found to produce gravel-sized mud clasts. These clasts could account for 20% or more of the eroded mass and significantly reduce the amount of silts and clays incorporated in suspended plumes during and immediately following placement.
