Повний текст джерелаLa thèse se focalise sur des applications des problèmes de flots dans des réseaux modélisant, d'une part des réseaux de distribution de fluide ou d'énergie et d'autre part des réseaux de télécommunication. Nous nous sommes intéressés à deux aspects :Le premier aspect consiste en une analyse de sensibilité des flots sur les réseaux de distribution, c'est à dire, l'étude de l'impact de la variation de la capacité d'une ou de plusieurs arêtes sur l'ensemble des valeurs de flot maximum entre toutes les paires de sommets du réseau. En outre, nous nous sommes intéressés à la rentabilité d'une arête donnée dans un réseau. Nous avons d'abord apporté des corrections à l'unique méthode qui existait dans le cas d'une capacité d'arête qui varie et nous avons proposé des algorithmes simples et efficaces pour résoudre le cas de plusieurs capacités qui varient. Nos méthodes sont basées sur les arbres de coupes de Gomory et Hu. 'Etant donné un réseau non orienté ayant capacités qui peuvent varier avec des paramètres lambda_1,\lambda_2, \lambda_3, \ldots \lambda_k, nous avons montré que 2^k calculs d'un arbre de coupes de Gomory et Hu étaient suffisants pour déterminer les valeurs de flot maximum entre toutes les paires de sommets dans le réseau. En ce qui concerne le problème de la rentabilité d'un lien, nous avons montré que juste 2 calculs d'un arbre de coupes de Gomory et Hu suffisaient pour déterminer l'ensemble des paires de sommets pour lesquelles tout flot maximum sature le lien cible. Le second aspect concerne l'allocation de ressources dans un réseau de télécommunication pour la satisfaction de requêtes d'utilisateurs. Pour ce faire, nous avons étudié ce problème par le biais de la tarification pour gérer la congestion tout en tenant compte du comportement des utilisateurs et de la volonté de profit del'opérateur. Nous avons utilisé une approche bi-niveaux pour résoudre le problème. Avec la méthode du Lagragien augmenté, nous résolvons le problème d'allocation de ressources en associant les multiplicateurs de Lagrange aux prix sur les liens du réseaux. Nous utilisons ensuite les conditions d'optimalité de Karush-Kuhn-Tucker pour vérifier si les ultiplicateurs (prix) sont uniques ou pas. Au cas de non unicité nous montrons comment on peut résoudre un deuxième problème d'optimisation sur ces multiplicateurs (prix) afin d'améliorer le revenu sur le réseau

Повний текст джерелаThis report is a project for a Bachelor of Science in mechanical engineering at Karlstads University. The project has been for Drinor AB and is a product development project. In pellet manufacture, the sawdust that is being used must achieve a certain degree of moisture in the fibers to be able to form. In today's commercial process, the sawdust is transported on a conveyor belt while it’s dried using thermal energy. Drinor AB has developed a mechanical dewatering press, which results in the sawdust not having to be dried for as long. This results in a new process with less energy consumption and a better environmental alternative. To maximize the compression of the sawdust, it is transported on a belt into the press with an even height. In this project, Drinor wants a solution for using the mechanical dewatering press to woodchips, since today's machine only works with sawdust. The problem with the woodchips is that they vary in size which makes it difficult to achieve a smooth mat for maximum compression in the roller nip. The aim of this project is to find a solution to this problem. This project is a product development project with phases like requirement specification, concept generation and prototype building. Five different concepts were produced where the most promising was further developed to the final result. Since this problem can ́t be solved by calculations, a prototype was produced by the concept that has been developed through a conceptualization process. With this prototype, tests can be performed, and a visual assessment is possible. Three different tests were conducted where each test involved an adjustment of the prototype to optimize the results and conclusions. After the tests, a concluded was made; that smooth rollers isn’t useful when working with woodchips. Because of the woodchips size variation, it became too problematic to proceed with this method. By ribbing the rollers feeding the woodchips to the conveyor belt, the smaller chips could be caught together with the larger ones. With the ribbed rollers, an output off the carpet could be examined and conclusions was made because of the results. To optimize the design, a stronger engine that can break the larger woodchips is highly recommended when woodchips sticks between rollers. Something that can stretch out the chipboard so that the same height is achieved across the conveyor belt, is also recommended.

Повний текст джерелаThis thesis consists of three independent chapters in the theme of rough path theory. Introduced in 1998 by Terry Lyons, this pathwise approach to stochastic differential equations (SDE) allows one to study SDE driven by processes that do not have the semi-martingale property which is required to apply the framework of the Itô integral. This is for example the case of the fractional Brownian motion for a Hurst index different from one-half. The first chapter deals with the links between rough path and regularity structure theories. The latter was recently introduced by Martin Hairer to solve a large class of stochastic partial differential equations. With the tools of this new theory, we show how to build the rough integral and the signature of an irregular path, which leads to solve a rough differential equation (RDE). In the second chapter, we focus on building RDE flows from their approximations at small scale, called almost flows. We show that under weak conditions on regularity of almost flows, although the uniqueness of the associated RDE solutions does not hold, we are able to select a measurable flow. Our general framework unifies the previous approaches by flow due to I. Bailleul, A. M. Davie, P. Friz and N. Victoir. In the last chapter, we study of a differential inclusion perturbed by a rough path, i.e. a RDE whose drift is a multivalued function. We prove, without convexity hypothesis and several conditions on the regularity of the drift, the existence of a solution

Estuarine density stratification may be controlled primarily by cross-shore processes (analogous to longitudinal control in narrow estuaries), or by both cross- and alongshore processes (typical of coastal plumes). Here field observations and numerical modeling are used to investigate stratification on the low-sloped, periodically inundated Skagit Bay tidal flats. Advection of stratification by the depth-averaged velocity, straining of the horizontal density gradient by velocity shear, and turbulent mixing are shown to be the dominant processes. On the south-central flats (near the south fork river mouth) velocities are roughly rectilinear, and the largest terms are in the major velocity direction (roughly cross-shore). However, on the north flats (near the north fork river mouth), velocity ellipses are nearly circular owing to strong alongshore tidal flows and alongshore stratification processes are important. Stratification was largest in areas where velocities and density gradients were aligned. The maximum stratification occurred during the prolonged high water of nearly diurnal tides when advection and straining with relatively weak flows increased stratification with little mixing. Simulations suggest that the dominance of straining (increasing stratification) or mixing (decreasing stratification) on ebb tides depends on the instantaneous Simpson number being above or below unity.

Повний текст джерелаBiodiversity is under enormous pressure from an increasing human population. Urbanisation, agriculture, and mining are just some of the factors responsible for the continuous degradation of the natural environment. Of these, urbanisation is one of the leading factors of diversity loss. To address this problem, it is necessary to understand the relationship between biodiversity and urban areas, as well as the relationship between society and biodiversity. This study focuses on these relationships and suggest ways in which urban biodiversity can be maximised without compromising on development. In order to create an urban environment that successfully supports maximised biodiversity, new methods and ideas must be developed to promote the protection of urban ecosystems. The Cape Floristic Region in South Africa is a good example of an area that requires immediate action in order to prevent enormous losses in biodiversity. Data have shown drastic decreases in natural vegetation cover in this area, and with its close to 9000 species, of which approximately 60% occurs nowhere else in the world. This state of affairs should be regarded as a serious crisis. This study consists of three main parts, the first being a literature review on the current relationships between the urban environment, society, and biodiversity. The second and third parts report on two empirical investigations on the campus of the Faculty of Health Sciences at the University of Stellenbosch in the City of Cape Town. The first of these investigates the possibility of using spirituality connected to nature as a promotional tool for conservation through rehabilitation or restoration of damaged urban vegetation habitats. For this purpose students’ and staff members’ opinions of the urban nature at the campus were tested. In the second investigation the options of restoring biodiversity to the campus was considered by exploring the best options available for rehabilitation while taking the current biodiversity status on and around the premises into account. This was carried out through three smaller projects that included the physical reintroduction of plant species, vegetation analysis, and bird identification and attraction. The response of employees and students at the Faculty of Health Sciences was found to be in favour of restoring vegetation and animal life to the campus. This is supported by a belief that their attitude towards their work would improve with improved natural surroundings. Initial rehabilitation attempts highlighted the complexity of rehabilitation practices by bringing forward challenges and problems experienced with the reintroduction of plant species. Despite these problems, increased plant diversity in experimental areas showed the possibility of successfully completing the project. Biodiversity analysis showed that methods of controlling vegetation used by the university are doing more harm than good, as it results in indigenous vegetation being displaced by exotic vegetation. This study introduces a number of questions regarding the relationship between urbanisation and biodiversity and to what extent the two should be linked. Hopefully it is a step in the direction towards marrying the urban and natural environment, and to create a sustainable urban environment where society no longer sees nature as something outside the city boundaries.

Повний текст джерелаAt the Skoghall pappermill, sulphatepaper pulp is produced in a continuous digester originally from 1969. To be able to maintain a high level of production there is a need for a process with few disturbances. Variations in how well the wooden chips are packed in the digester is one form of disturbance. Today there are no available measurements on how well the chips are packed. Instead this is regarded as being constant.
The variation in the so called bulk density of the chips is mainly due to variations in the percentage with small dimensions. Chips are classified in relation to their size and one of the smallest classes is referred to as pin chips. These are believed to have a big impact on the bulk density. The amount of pin chips fluctuate more then the other classes, there by causing disturbances.
The Skoghall pappermill has invested in a ScanChip. This is an instrument that measures the dimensions of the chips optically. ScanChip presents figures on chip quality, including a measurement of the bulk density. However, it has been shown that this measurement is not valid for the Skoghall pappermill. By using data from ScanChip a model that predicts how well the chips are packed has been devised. This value is the bulk density divided by the basic density. The model has proved to yield good results, despite a relatively small amount of data.
A theoretical value of the amount of produced pulp has been computed based on the revolutions of the production screw that feeds chips into the digester. This value takes in consideration how well the chips are packed. The value has shown great similarities with the empirical measurements that are used today. A simulation during one month has shown that differences in the mixture of chips have effected the measurement of produced pulp with up to 7 ton/h.
Chips are stored in open pile storages before they are being used in the process of transforming them into pulp. Four screws are used to move chips from the piles to conveyer belts. It has been shown in work done previously, that the movement of the screws contributes to variations in the amount of pin chips measured by ScanChip.
During the work with this master’s thesis I have found that there are variations in the piles that make it difficult to predict the amount of pin chips accordingly. However by filtering the measurements of pin chips to remove these variations, the results are improved. A new way of controlling the movements of the screws was operational on the 10 of March and this improved the results.
The direction in which the screws are moving influence the speed of the screws, mainly in the pile with the so called sawmill chips. By changing the amount of chips that each screw puts out, the differences in speed have been reduced. The mixtures found in the two piles are not completely homogenous. There are a greater amount of pin chips in the northern parts compared with the southern parts. This could be an effect of the wind direction, and will still cause variations.

Повний текст джерелаEsta tesis contribuye a avanzar en el conocimiento del funcionamiento hidrogeológico de los salares con el fin de mejorar la gestión de sus recursos minerales y ecosistemas. Los salares son una fuente principal de Li, B, I, K, Mg y NaCl, y albergan algunos de los ecosistemas más excepcionales de la tierra. Alrededor del 25 % de las reservas mundiales de Li se localizan en el Salar de Atacama (NE de Chile). La explotación de esta materia prima, altamente valorada en las industrias tecnológica y farmacéutica, se realiza mediante bombeo de salmuera. El bombeo de salmuera puede afectar al régimen hídrico natural de los salares y, en muchos casos, se desconoce el posible impacto sobre sus ecosistemas. Esta tesis ayuda a (1) explicar la geometría y el flujo subterráneo de la zona de mezcla (interfaz salina) ubicada alrededor de los salares, (2) definir el balance hídrico y la hidrodinámica del Salar de Atacama en su régimen natural, (3) analizar y cuantificar los impactos causados por el bombeo de salmuera, (4) mejorar el diseño de las explotaciones de salmuera en salares y (5) cuestionar las ideas tradicionales que explican el origen del enriquecimiento en Li del Salar de Atacama. El agua subterránea recargada en las montañas es forzada a fluir hacia la superficie cuando alcanza la zona de mezcla que rodea al salar debido a su menor densidad, alimentando los ecosistemas lagunares y humedales. La primera cartografía 3D de la zona de mezcla de un salar se ha llevado a cabo en el Salar de Atacama, evidenciando una pendiente mucho menor que las predicciones anteriores. El modelado 2D de la zona de mezcla ha demostrado que cuanto mayor es la permeabilidad del acuífero superior, más baja es la pendiente y más superficial se vuelve la zona de mezcla. Por lo tanto, la permeabilidad del acuífero superior, principalmente constituido por evaporitas karstificadas y depósitos aluviales muy permeables, es crítica para la geometría de la zona de mezcla. El modelo hidrogeológico conceptual del Salar de Atacama, previo al bombeo de salmuera (régimen natural), se ha definido y validado utilizando un modelo estacionario 3D del flujo subterráneo. La distribución asimétrica de la recarga por infiltración del agua de lluvia y, sobre todo, de la descarga por evaporación da como resultado una superficie freática cuyo mínimo nivel hidráulico se localiza en el sector más oriental del núcleo, cerca de la zona de mezcla oriental. El modelado transitorio 3D de la cuenca del Salar de Atacama desde 1986 hasta 2018 ha permitido explicar los impactos causados por la explotación de salmuera sobre la hidrodinámica y el balance hídrico. Desde 1994 hasta 2015, el bombeo de salmuera causó una profundización de la superficie freática que desencadenó una reducción de la evaporación freática. Este efecto ha sido definido como la "capacidad de autorregulación" y permite a los salares contrarrestar las perturbaciones ocasionadas por eventos naturales o antropogénicos sobre la superficie freática y el balance hídrico. La capacidad de autorregulación compensó, al menos en parte, la disminución de la descarga por evaporación, pero hoy en día ya está amortizada en el núcleo y la zona de mezcla comienza a verse afectada. El modelado 3D de un hipotético salar bajo explotación de salmuera ha contribuido a optimizar la distribución espacial de los pozos de bombeo en términos de impacto sobre el balance hídrico. Para aprovechar al máximo la capacidad de autorregulación, las explotaciones de salmuera deben considerar distribuir el caudal bombeado en la mayor área posible. Los resultados del modelado hidro-termo-halino de una sección vertical Este-Oeste de la cuenca del Salar de Atacama han señalado al Sistema de Fallas Salar (SFS), localizado en el sector central del núcleo, como el principal contribuyente para explicar el enriquecimiento extremo en Li, ya sea por el ascenso de salmueras ricas en Li desde un reservorio hidrotermal profundo o por removilización de antiguas capas de sales y/o arcillas ricas en Li por aguas de recarga no evaporadas provenientes del Oeste. La localización del mínimo nivel hidráulico regional en el lado oriental del núcleo descarta considerar la evaporación avanzada como un mecanismo actual para alcanzar el alto contenido de Li de las salmueras ubicadas sobre el SFS. Además, la persistencia de las zonas de mezcla en profundidad también permite descartar las hipótesis previas de 1) infiltración de salmueras desde los salares actuales del Altiplano-Puna y 2) lixiviado de hipotéticos salares enterrados por erupciones volcánicas en el Altiplano-Puna como origen del enriquecimiento excepcional en Li de las salmueras de Salar de Atacama.

We use this to solve the continuous cohomological equation of the Anosov flow ℱ on the hyperbolic torus TAⁿ⁺¹ obtained from A by suspension. This enables us to compute some other geometrical objects associated to the diffeomorphism A and the foliation ℱ like the invariant distributions and the leafwise cohomology

Повний текст джерелаThis work concerns the testability analysis of data-flow designs of reactive systems developed by using two development environments SCADE and SIMULINK. The testability, which is used to estimate the facility to test a system, is a combination of two measures : controllability an observability. We use the SATAN technology, which is based on the information theory, to model the transfer of information in the system. The testability measures are computed from the loss of information in the system, where each operator contributes to this loss. The loss of information of an operator can be evaluatedeither exhaustively by basing on the "truth table" of the function of the operator, or statistically by basing on the simulation results of the operator. Our approach is integrated in a tool allowing an automatic analysis of testability of graphical data-flow designs of reactive systems

Повний текст джерелаIn critical systems, applications must satisfy hard timing constraints, each task must execute in a maximum predefinite time. Any unrespected constraint may compromise the stability of the whole system and generate disastrous effects. Such a system is called hard real-time system. To be able to assign a constraint to a task, you must be able to determinate the maximum time this task will execute, independently from the input data of the task. This maximum time you search is called the WCET (Worst Case Execution Time), it is obtained by a calculation process where we need to modelise the structures of the processor architecture. The architecture mechanisms increasing performance (caches, branch prediction) are often a lot undeterministic and thus are difficult to modelise. That's why we usually prefer using relatively simple architectures for a hard real-time system, or simplifying recent high-performance architecture. In this work, we will rather adapt, using small modifications, one of those high-performance but little predictible architecture to respect hard timing constraints and make simpler WCET calculation. We choose the Simultaneous Multithreading architecture where several programs can run at the same time sharing the resources of one core only
