Texte intégralRésumé :
The capsular polysaccharides of Escherichia coli are immunogenic and antigenic. When conjugated to a carrier protein these polysaccharides can be used as vaccines. A knowledge of the structure of bacterial capsular polysaccharides is essential for understanding antibody-antigen interaction and also for understanding the chemical basis of serological differentiation. For these reasons structural studies of some E. coli capsular polysaccharides are being undertaken in this laboratory.
In this thesis a preliminary investigation into the structures of capsular polysaccharides from E. coli serotypes K/46, K/47, K/48, K49 and K50 is presented. The qualitative composition of each polysaccharide was determined by varying the hydrolytic conditions used to cleave the glycosidic bonds between the monosaccharide units. Table I shows the sugars present in each capsular polysaccharide. [Table Omitted]
The ratio of the sugars in each polysaccharide was determined using methanolysis followed by reduction with sodium borohydride. The presence of amino sugars was confirmed by deamination of the hydrolyzed polysaccharide and detection of the product by g.l.c.
G.l.c.-m.s., of the alditol acetates of the monosaccharides obtained by hydrolysis of the polysaccharides, was used to confirm the type of monsaccharide. present in each polysaccharide,
₁H-N.m.r. spectroscopy was utilized to confirm the presence of deoxy sugars, amino sugars and non-carbohydrate substituents. E. coli K47 and K50 capsular polysaccharides were both found to have pyruvate present as a substituent.
A bacteriophage was isolated from sewage for each of E. coli K47, K48 and K49 serotypes. Phage 47 also attacked E. coli K48 and K49 bacteria.
The structure of E. coli K26 capsular polysaccharide was investigated using the techniques of acid hydrolysis, carbodiimide reduction and methanolysis followed by reduction with sodium borohydride. The polysaccharide was degraded using a bacteriophage-borne glycanase. The position of cleavage found by methylation of the reduced oligosaccharide. Combination of the data obtained from the chemical analysis, n.m.r spectroscopy and the bacteriophage degradation gave the two following possible structures for the E. coli K26 capsular polysaccharide.

Nguyen, The Quyen. « Caractérisation structurale du recrutement de la protéine JIP1 par la chaîne légère (KLC) de la kinésine1 ». Thesis, Université Paris-Saclay (ComUE), 2017. http://www.theses.fr/2017SACLS250/document.
Texte intégralRésumé :
RésuméLes kinésines sont des moteurs moléculaires impliqués dans le transport intracellulaire de nombreux cargos au sein de la cellule. Bien que la motilité des kinésines soit bien comprise, les mécanismes moléculaires à la base du recrutement des cargos le sont beaucoup moins.La kinésine1 joue divers rôles dans les cellules neuronales, où elle contribue à l’organisation spatiale et temporelle de nombreux composants cellulaires. Elle jouerait un rôle dans différentes pathologies neurologiques, comme la maladie d’Alzheimer. Comprendre comment la kinésine1 reconnaît et interagit avec ses cargos est important pour déterminer son rôle, ainsi que celui de ses cargos, au niveau du fonctionnement des cellules normales et pathologiques. La kinésine1 est un hétérotétramère constitué de deux chaînes lourdes (KHC) et de deux chaînes légères (KLC) toutes deux étant capables de recruter des protéines cargos. L’une des premières protéines cargos à avoir été identifiée est JIP1 (JNK-interacting protein 1) qui est, entre autres: (i) une protéine d’échafaudage pour la voie de signalisation des MAP kinases et (ii) une protéine adaptatrice pour le transport de la protéine précurseur de l’amyloïde (APP) responsable de la maladie d’Alzheimer. Dans les deux cas, JIP1 régule des processus critiques au niveau de la cellule, ce qui en fait une protéine intéressante à étudier. Des premières études ont permis de mieux comprendre comment JIP1 est recrutée et transportée par la kinésine1. Cependant, le détail de l’interaction entre KLC et JIP1 n’est pas encore complètement décrit et donc compris.Objectifs : Mon travail de doctorat vise à caractériser au niveau moléculaire l’interaction entre KLC et JIP1. Pour ce faire, j’avais pour objectifs : 1) de caractériser les domaines d’interaction des deux protéines seules, 2) d’étudier la formation du complexe en solution par des approches biophysiques et 3) de déterminer la structure 3D du complexe par cristallographie.Résultats : Dans un premier temps, j’ai caractérisé le domaine TPR de KLC seul en contribuant entre autres au développement d’une boite à outils moléculaires. J’ai aussi participé à la détermination de deux structures cristallographiques du domaine TPR de KLC1/2 permettant de mettre en évidence la plasticité structurale de la 1ère hélice de ce domaine (Nguyen et al, soumis). Dans un second temps, j’ai mis en place les conditions d’expression et de purification du domaine PTB de JIP1 et mener la caractérisation structurale de ce domaine en solution. Bien que ce domaine de JIP1 ne soit pas nécessaire pour l’interaction avec KLC, j’ai pu étudier l’impact de sa présence au niveau du recrutement par KLC. Finalement, j’ai caractérisé le recrutement de JIP1 par KLC en confirmant tout d’abord un certain nombre d’information sur l’interaction entre le domaine TPR de KLC et la région C-terminale (Cter) de JIP1 au niveau moléculaire. Les nombreux essais de cristallisation que j’ai menés n’ont pas permis d’obtenir des cristaux du complexe KLC:JIP1. J’ai cependant pu cartographier de façon précise la zone d’interaction de JIP1-Cter avec le domaine TPR de KLC en employant les différents outils de KLC disponibles pour déterminer par calorimétrie leur affinité avec JIP1-Cter (Nguyen et al., en préparation).Conclusion : Ainsi, mon travail de doctorat a permis de mieux comprendre 1) la versatilité structurale du domaine TPR de KLC, 2) l’impact du domaine PTB de JIP1 pour son recrutement par KLC et 3) le mode d’interaction de JIP1 par KLC. Sur la base de ces données, je discuterai les bases structurales du mode d’interaction de KLC avec JIP1 et le comparerai à celui de KLC avec les cargos à motif WD, comme SKIP et Alcadéine-αAbstractKinesins are molecular motors involved in the intracellular transport of many cargos within the cell. Although the motility of kinesins is well understood, the molecular mechanisms underlying cargo recruitment are much less so.Kinesin1 plays various roles in neuronal cells, where it contributes to the spatial and temporal organization of many cellular components. It would play a role in various neurological pathologies, such as Alzheimer's disease. Understanding how kinesin1 recognizes and interacts with its cargos is important to decorticate its role, as well as that of its cargos, in normal and pathological cells. Kinesin1 is a heterotetramer consisting of two heavy chains (KHC) and two light chains (KLC), both of which are capable of recruiting cargo proteins. One of the first cargo proteins to have been identified is JIP1 (JNK-interacting protein 1) which is: (i) a scaffold protein for the signaling pathway of MAP kinases and (ii) an adaptor protein for transporting amyloid precursor protein (APP) responsible for Alzheimer's disease. In both cases, JIP1 regulates critical processes at the cell level, making it an interesting protein to study. Early studies have led to a better understanding of how JIP1 is recruited and transported by kinesin1. However, the detail of the interaction between KLC and JIP1 is not yet fully described and therefore understood.Objectives: My doctoral work aims at characterizing at the molecular level the interaction between KLC and JIP1. To do this, I had the following objectives: 1) to characterize the interaction domains of the two proteins alone, 2) to study the formation of the complex in solution by biophysical approaches, and 3) to determine the 3D structure of the complex by crystallography.Results: Initially, I characterized the TPR domain of KLC alone, contributing among others to the development of a molecular toolbox. I also participated in the determination of two crystallographic structures of the TPR domain of KLC1/2 that highlights the structural plasticity of the first helix of this domain (Nguyen et al, submitted). In a second step, I set up the conditions for the expression and purification of the PTB domain of JIP1 and carry out the structural characterization of this domain in solution. Although this domain of JIP1 is not necessary for interaction with KLC, I studied the impact of its presence on recruitment by KLC. Finally, I characterized the recruitment of JIP1 by KLC by confirming a number of information on the interaction between the KLC-TPR and the C-terminal region (Cter) of JIP1 at the molecular level. The numerous crystallization tests that I carried out did not make it possible to obtain crystals of the KLC: JIP1 complex. However, I was able to precisely map the interaction zone of JIP1-Cter with the KLC-TPR domain using the various KLC tools available by determining by ITC their affinity with JIP1-Cter (Nguyen et al., In preparation ).Conclusion: Thus, my PhD work allowed to better understand 1) the structural versatility of the KLC-TPR domain, 2) the impact of the JIP1-PTB domain for its KLC recruitment, and 3) the interaction mode of JIP1 by KLC . On the basis of these data, I will discuss the structural basis of the mode of binding of KLC with JIP1 and compare it with that of KLC with WD-motif cargo, such as SKIP and Alcadein-α

Mestrado em Contabilidade, Fiscalidade e Finanças EmpresariaisA Air France-KLM (AF-KLM) é a companhia de bandeira da França, é resultado da fusão entre as empresas Air France (francesa) e KLM (holandesa) possuindo dois hubs principais situados em Paris e Schipol. O grupo é atualmente líder da europa em termos de tráfego e tem como objetivo ser uma das maiores companhias à escala global. O trabalho final de mestrado que se segue tem como objetivo principal estimar o valor intrínseco das ações da AF-KLM para 31 de dezembro de 2018. Este projeto é composto por uma revisão bibliográfica onde são analisados os métodos de avaliação possíveis e a partir da qual é definida a metodologia para este mesmo projeto. Foi também feita uma análise em relação ao ambiente macroeconómico, da indústria e especificamente da AF-KLM. De forma a calcular o valor intrínseco procedeu-se à avaliação por fluxos de caixa atualizados baseado em valores de FCFF pelo qual foi determinado um valor intrínseco de 11.33 euros para as ações da AF-KLM para a data de 31 de dezembro de 2018. Este valor sugere que as ações se encontram subvalorizadas e que possuem um potencial de crescimento de 19.55% face ao preço de 9.48 euros registado a 31 de dezembro de 2018. Através da avaliação relativa foram utilizados dois múltiplos, em que o enterprise valueto-EBITDA resultou num preço de 23.5 euros por ação e o price-to-earnings foi igual a 5.3 euros por ação culminando numa média de 14.43 euros por ação que corresponde a um potencial de crescimento de 52.2%.
Air France-KLM (AK-KLM) is the flag carrier of France resulted of the fusion between Air France (french) and KLM (dutch). It has two main hubs located in Paris and Schipol. The group is the current european leader in passenger traffic and aims to be one of the world's best airline companies. The following project aims to estimate the intrinsic value of AF-KLM's stock price as of December 31, 2018. It consists of a literature review where possible evaluation methods are analysed from which the methodology of this project is defined. An analysis was also made of the macroeconomic environment, industry and the company's specifics. In order to estimate the intrinsic value, cash flow discount model based on FCFF values was carried out whereby an intrinsic value of 11.33 euros was determined for AFKLM's shares as of 31 December 2018. This result suggests that shares are undervalued and have a growth potential of 19.55% compared to the closing price of 31 December 2018 (9.48 euros). Through the relative valuation two multiples were used, in which enterprise-value-to-EBITDA resulted in 23.5 euros per share and where the price-toearnings ratio gave a price of 5.3 euros per share, culminating in an average of 14.43 euros per share which corresponds to a growth potential of 52.2%.

Texte intégralRésumé :
Khovanov-Lauda-Rouquier algebras, or KLR algebras, are a family of algebras known to categorify the upper half of the quantized enveloping algebra of a given Lie algebra. In finite type, these algebras come with a family of standard modules, which correspond to PBW bases under this categorification. In this thesis, we show that there are no non-zero homomorphisms between distinct standard modules and that all non-zero endomorphisms of standard modules are injective. We then apply this result to obtain applications to the modular representation theory of KLR algebras. Restricting our attention to finite type A, we are then able to compute explicit projective resolutions of all standard modules. Finally, in finite type A when alpha is a positive root, we let D be the direct sum of all distinct standard modules and compute the algebra structure on Ext(D, D).

Ward, Kiron. « Fictional encyclopaedism in James Joyce, Leslie Marmon Silko, and Roberto Bolaño : towards a theory of literary totality ». Thesis, University of Sussex, 2017. http://sro.sussex.ac.uk/id/eprint/68802/.
Texte intégralRésumé :
This thesis makes an intervention in the recent proliferation of work on encyclopaedism in fiction. By taking James Joyce's Ulysses, Leslie Marmon Silko's Almanac of the Dead, and Roberto Bolaño's 2666 as its case studies, the project proposes that fictional encyclopaedism can be read through the responses authors make to the diverse forms that encyclopaedic thought and practice has taken throughout history. In this, I contend, ‘encyclopaedism' can be dissociated from its commonplace conflation with ‘great white male' theories of literature, and refigured as a literary category with the potential to restructure, or decolonise, both our sense of ‘greatness' and ‘mastery' in fiction and our idea of the world as a complete and coherent totality. The project is divided into five sections. The introduction establishes the relationship between encyclopaedism and totality through a reading of the Encyclopaedia Britannica's ‘Great American Indian Leaders' exhibition in the 1980s, drawing particularly on the theoretical work of Gerald Vizenor and Walter D. Mignolo and on historians of encyclopaedism. The first and second chapters look to the ways Joyce and Silko, respectively, critique and re-tool specific forms of encyclopaedism, with Ulysses focusing on the Britannica and Almanac of the Dead reaching back to the encyclopaedic practices that gave epistemic shape to the European ‘conquest,' or invasion, of the Americas (particularly those of Bartolomé de Las Casas). Both authors, I propose, imagine new, radical, decolonial encyclopaedisms that work by opening themselves up to their own productive failures. The third chapter explores how Bolaño uses 2666 to identify potential encyclopaedisms immanent to the contemporary, particularly through his dialogue with Julio Cortázar's Hopscotch. The conclusion synthesises the three authors' forms of fictional encyclopaedism into the beginnings of a theory of literary totality as ‘totality-without-totality,' along the lines of Jacques Derrida's ‘messianism-without-messianicity.'

Texte intégralRésumé :
La empresa KLM Group SAC es una concesionaria de DERCO Perú que
brinda los servicios de comercialización de vehículos y, además del servicio de
mantenimiento preventivo y correctivo para todas las unidades de la marca que vende,
actualmente cuenta con dos locales ubicados en San Agustín de Cajas y tiene 30 trabajadores
que laboran en un solo turno, el principal problema identificado en KLM automotriz es la
distribución de sus locales porque las rutas de acceso son altamente transitables lo que
dificulta el acceso, así también la estructura actual es inadecuada, y además para la
proyección de crecimiento que tiene KLM automotriz al 2023 será insuficiente el espacio con
el que cuenta actualmente. Así mismo los protocolos de atención de venta y postventa no
están correctamente determinados para la satisfacción total del cliente, otros puntos débiles
de KLM automotriz son los tiempos de entrega y los financiamientos de vehículos.
En el presente proyecto se desarrollarán propuestas de solución para los distintos
problemas, uno de los más resaltantes es la redistribución y ubicación de la empresa, será
necesario habilitar un local exclusivo para el área de planchado y pintura, realizar
modificaciones en la estructura actual delimitando y separando adecuadamente las distintas
áreas e incrementar el tamaño para las áreas que lo requieran. Mejorar el cumplimiento de
protocolos de atención e implementar también una ruta para la prueba de manejo de manera
que el cliente experimente con los vehículos. También se tiene que trabajar de manera más
proactiva en las alianzas con las distintas entidades financieras y optimizar los tiempos de
entrega en vehículos y placas para incrementar la satisfacción de los clientes.The company KLM Group SAC is a DERCO Perú’s dealership, which provides services of vehicle’s marketing, and it also provides services of preventive and corrective maintenance for all brand’s units sold by the company. Currently it has two premises located in San Agustin de Cajas and has 30 employees that work in a single shift. The main problem identified at KLM Automotriz is the distribution of their premises because the access routes are in high-transit areas, which makes it difficult to access them. Additionally the current structure is inadequate, and also the space that KLM Automotriz currently has will not be enough for 2023 projected growth. Likewise, protocols for sales and post-sales are not correctly determined to totally satisfy the client. Some other weak points at KLM Automotriz are delivery time and vehicles financing. This project will develop proposals of solutions for the different problems. One of the most outstanding is the company’s redistribution and location. It will be necessary to enable an exclusive premise for the filling and painting area; to do some modifications to the current structure by adequately defining and separating different areas, and to increase the size of areas that require it. It is also necessary to improve compliance on customer service protocol, and implementing a route for driving test so the client can experiment with vehicles. Additionally, it is necessary to work more proactively on alliances with different financial institutions and optimize vehicle and license plates delivery time to increase client’s satisfaction.

Maksimau, Ruslan. « Algèbres KLR et algèbres de carquois-Schur ». Sorbonne Paris Cité, 2015. http://www.theses.fr/2015PA077160.
Texte intégralRésumé :
Dans la première partie de la thèse on construit une base de la partie positive f de l'algèbre quantique de Drinfeld-Jimbo associée à un carquois de Dynkin. Cette base est donnée par des faisceaux de parité en caractéristique quelconque. De plus, on catégorifie la multiplication et la comultiplication dans f avec des complexes de faisceaux. Dans la deuxième partie il s'agit de la dualité de Koszul. Stroppel et Webster ont introduit une graduation sur la q-algèbre de Schur cyclotomique S. On démontre que l'algèbre graduée obtenue est Morita équivalente (au sens gradué) à une algèbre de Koszul. La preuve est basée sur le résultat de Rouquier, Shan, Varagnolo et Vasserot qui identifie la catégorie mod(S) avec une catégorie O affine parabolique de type A. Cette catégorie admet une graduation de Koszul construite par Shan, Varagnolo et Vasserot. On identifie cette graduation avec la graduation sur mod(S). Dans la troisième partie de la thèse on étudie une représentation catégorique dans la catégorie O parabolique pour la version affine de gl(N) de niveau -N-e. Cette catégorie admet une structure de représentation catégorique de sl(e) affine avec des foncteurs E et F. Che vma Cette catégorie contient une sous-catégorie plus petite A qui catégorifie l'espace de Fock de niveau supérieur. On démontre que le foncteur F pour la catégorie A de niveau -N-e se décompose en terme de composantes du foncteur F pour la catégorie A de niveau -N-e-1. Pour démontrer cela, on construit un isomorphisme entre l'algèbre KLR associée au carquois cyclique à e points et un sous-quotient de l'algèbre KLR associée au carquois cyclique à e+1 pointsIn the first part of the thesis we give a construction of a basis of the positive part f of the Drinfeld-Jimbo quantum enveloping algebra associated with a Dynkin quiver. This basis is given in terms of parity sheaves over fields in any characteristic. We also categorify both the multiplication and the comultiplication of f via complexes of sheaves. The second part deals with Koszul duality. Stroppel and Webster have introduced a grading on the cyclotomic q-Schur algebra S. We prove that the obtained graded algebra is graded Morita equivalent to a Koszul algebra. The proof is based on a result of Rouquier, Shan, Varagnolo and Vasserot that identifies the category mod(S) with a subcategory of an affine parabolic category O of type A. This subcategory admits a Koszul grading constructed by Shan, Varagnolo and Vasserot. We identify this Koszul grading with the grading on mod(S). In the third part of the thesis we study a categorical representation in the parabolic category O for affine gl(N) at level -N-e. This category admits a structure of a categorical representation of affine sl(e) with respect to some functors E and F. This category contains a smaller category A that caregorifies the higher level Fock space. We prove that the functor F for the category A at level -N-e can be decomposed in terms of the components of the functor F for the category A at level -N-e-1. To prove this, we construct an isomorphism between the KLR algebra associated with the cyclic quiver with e vertices and a subquotienl of the KLR algebra associated with the cyclic quiver with e+1 vertices

Texte intégralRésumé :
The usage of formal logic to solve problems in artificial intelligence has a long history in the field. Information is represented in a formal language, which facilitates algorithmic reasoning about some domain knowledge. Traditionally, the algorithms used for the reasoning services are monotonic, which states that adding knowledge never causes the retraction of an inference. A result of this is that if the knowledge in question contains examples that are exceptions to stated rules, then the entire knowledge base may become unsatisfiable. If the knowledge accurately represents the domain, then such a result is undesirable. One solution is nonmonotonic reasoning, which encompasses patterns of defeasible or “common sense” reasoning that may retract conclusions upon the addition of new information to a knowledge base. One of the most prominent frameworks for nonmonotonic reasoning is the one defined by Kraus, Lehmann, and Magidor (KLM). The KLM framework has very desirable features both for theoretical study of nonmonotonic reasoning, as well as for implementation in AI applications. However, the current state of the KLM framework spans numerous papers over two decades of research. This provides a challenge for new researchers to understand the current problems being studied, as well as to understand the framework well enough to either extend it or apply it. This dissertation aims to compile the theoretical work done in this framework to provide a single point of reference for anyone wishing to understand the KLM framework, as well as to know how to define a defeasible entailment relation, using homogenised terminology and notation that is now typical of the field. Firstly, the propositional logic used as the base language will be defined. Then, paralleling the way the framework was historically built up, a preferential semantics over that language will be described, before modifying the language itself with a defeasible connective, and introducing a nonmonotonic entailment relation over such a language. Then, recent extensions to this framework defining various classes of defeasible entailment are described. By the end of this dissertation, the reader should have a well rounded understanding of the KLM framework, from classical logic to defeasible logic.

Texte intégralRésumé :
This thesis consists of two parts. In the first we prove that the Khovanov-Lauda-Rouquier algebras $R_\alpha$ of finite type are (graded) affine cellular in the sense of Koenig and Xi. In fact, we establish a stronger property, namely that the affine cell ideals in $R_\alpha$ are generated by idempotents. This in particular implies the (known) result that the global dimension of $R_\alpha$ is finite.
In the second part we use the presentation of the Specht modules given by Kleshchev-Mathas-Ram to derive results about Specht modules. In particular, we determine all homomorphisms from an arbitrary Specht module to a fixed Specht module corresponding to any hook partition. Along the way, we give a complete description of the action of the standard KLR generators on the hook Specht module. This work generalizes a result of James.

Texte intégralRésumé :
Bakgrund: Vid välgrundad misstanke om lymfom eller KLL (kronisk lymfatisk leukemi) skapatienten utredas enligt SVF (standardiserat vårdförlopp) för lymfom/KLL. Patienten måsteuppfylla minst ett av sex kriterier för att uppnå detta. SVF-programmen infördes för att kortaväntetiderna och minska regionala skillnader inom cancervården.Syfte: Att se hur ingången i SVF-utredningen (vilket kriterium patienten uppfyllde för remiss)påverkar utgången. I studien undersöks också vilka kriterier och lymfomdiagnoser som ärvanligast, vilka diagnoser patienter får istället för lymfom och hur stor andel av patienternasom remitteras på fel grund.Metod: En retrospektiv journalgranskning genomfördes med alla patienter som remitteratsenligt SVF lymfom/KLL inom Region Örebro län från starten 2016 till november 2020 somstudiepopulation. Totalt granskades 549 journaler, 546 patienter inkluderades i resultatet.Information inhämtades om: ålder vid start av SVF, kriterium som föranledde välgrundadmisstanke om lymfom/KLL, vilken lymfomdiagnos patienten fick och vilken diagnospatienten fick vid avsaknad av lymfom/KLL. Resultat: Kriterierna som starkast korrelerade med diagnos av lymfom/KLL var lymfocytos,M-komponent i serum, och biopsi. Vanligaste lymfomdiagnosen var aggressivt Bcellslymfom(N=162, 49,5%). Vanligaste diagnosen istället för lymfom/KLL varospecificerad lymfkörtelförstoring (N=90, 50,3%). Vanligaste kriterierna för välgrundadmisstanke var bilddiagnostik (N=210, 41,7%) och biopsi (N=197, 39,1%). 42 (7,7%) avpatienterna saknade välgrundad misstanke. 45 (8,9%) patienter fick någon annancancerdiagnos än lymfom/KLL.Slutsats: Relativt många patienter remitterades på fel grund och denna andel var större hoskvinnorna. Palpabel mjälte som kriterium var mycket ovanligt och ledde inte till någonlymfom/KLL-diagnos. Om resultatet av denna studie är generaliserbart för hela landet skullekriteriet kunna rekommenderas att uteslutas.

For a balanced order, we study imaginary semicuspidal modules by means of `imaginary Schur-Weyl duality'. We then generalize this theory from balanced to arbitrary convex preorders for affine ADE types. Under the assumption that the characteristic of the ground field is greater than some explicit bound, we prove that KLR algebras are properly stratified. We introduce affine zigzag algebras and prove that these are Morita equivalent to arbitrary imaginary strata if the characteristic of the ground field is greater than the bound mentioned above. Finally, working in finite or affine affine type A, we show that skew Specht modules may be defined over the KLR algebra, and real cuspidal modules associated to a balanced convex preorder are skew Specht modules for certain explicit hook shapes.

Texte intégralRésumé :
Il y a plus de trente ans, les physiciens ont montre un interet particulier pour les desintegrations semi-leptoniques du kaon, Kl4. Les mesures des observables liees a ces desintegrations fournissent des informations importantes sur les interactions faible et forte. Nous considerons ces desintegrations dans le cadre de la theorie desperturbations chirale basee sur un Lagrangien effectif dont les degres de liberte ne sont pas uniquement les mesons pseudo-scalaires mais aussi les leptons legers et le photon. Il existe de nombreuses experiences de basse energie et de haute precision, comme E865, Dafne, Na48/2 et KTeV, visant a mesurer ces modes avec une precision jamais atteinte auparavant, grace a une augmentation considerable de la statistique. L'exploitation de ces donnees de haute precision rend incontournable la necessite de controler d'une maniere quantitative certains effets indesirables dont les corrections radiatives. Nous avons evalue, analytiquement et numeriquement, ces effets a l'ordre d'une boucle et considere la brisure d'isospin due a la difference de masse des quarks legers.

Schroeder, Seton S. « Hyperspectral Image Compression Using a Two-Stage KLT ». DigitalCommons@CalPoly, 2009. https://digitalcommons.calpoly.edu/theses/85.
Texte intégralRésumé :
A computationally efficient, lossy, bandwidth compression scheme for hyperspectral imagery is presented. In certain cases, the direct application of the standard KLT algorithm over an entire data set is not practical. The data may be too large for efficient processing by one encoder and so portions of the entire data set may necessarily be sampled by different encoders. The algorithm proposed handles such a limitation by leveraging the standard JPEG 2000 technology. The component decorrelation of the JPEG 2000 (extension 2) is replaced with a two-stage Karhunen-Loeve Transformation (KLT) operation resulting in a reduction in the computational complexity. At the first stage the spectral data is partitioned into sets of adjacent spectral images, which are decorrelated independently of one another. At the second-stage inter-partition correlation is exploited by combining principle component images and performing a second set of KLT operations. It is shown that reconstructed image quality is improved by minimizing partition size at the first stage. The method is evaluated using the criteria of root-mean-square error as well as the performance of a terrain-classification algorithm. A relationship between partition size and minimal inter-partition decorrelation is also proposed and may act as a guide in the tuning of compression settings.

Texte intégralRésumé :
Kan matematiken kläs i ett skimmer av glädje genom matematikutveckling? I olika studier (bland annat PISA, 2003 och TIMSS, 2003) som vi tagit del av visas ett sjunkande intresse och kunskap hos skolelever i matematik. Utifrån detta har vi valt att studera en norrländsk kommun och deras satsningar på matematikutveckling. Genom intervjuer med politiker, tjänsteman, matematikutvecklare, rektorer och lärare kan vi konstatera att dessa strävar mot samma mål när det gäller matematikutveckling, elevernas matematikkunskaper måste förbättras. Respondenterna anser att kompetensutveckling för lärare är av vikt för att elevers matematikutveckling skall höjas, men hur denna kompetensutveckling skall ske skiljer sig åt. Det pratas om traditionell kompetensutveckling såväl som kompetensväxling och matematikutvecklare för att utbilda och stötta lärare. I studien kan vi se att den kommun som undersöktes bara har påbörjat sin matematiksatsning, medan matematikdelegationen (SOU 2004) hade som mål att år 2006 skulle alla kommuner i landet ha påbörjat utbildning av och arbetet med matematikutvecklare. De lärare som deltog i studien har gemensamt med rektorerna att de tycker att läromedlen styr för mycket. Lärarna måste få en chans att utveckla sina matematiklektioner och det är här som skillnaderna i hur denna utveckling skall ske uppdagar sig. Rektorerna och en av lärarna menar att det är traditionell kompetensutveckling, det vill säga den kompetensutveckling som kommunen erbjuder, som i första hand bör nyttjas, medan det övriga lärarna till största del talar om erfarenhetsutbyte lärare emellan. Vi kan konstatera att ännu kan matematiken inte kläs i ett skimmer av glädje. Eftersom att alla inblandade har en vilja att utveckla matematikämnet finns det stora förhoppningar att detta kommer att kunna ske i framtiden.

Texte intégralRésumé :
Denna studie belyser hur två myndigheter och en organisation arbetar med frigivna fångar med mål att nå en förändring. Återfall i brott är ett vanligt problem, 44 procent av alla frigivna män i Sverige återfaller inom tre år. Brist på uthållighet och låg självkänsla är två orsaker till återfall. Vi har genomfört en kvalitativ studie baserad på information från tre informanter som arbetar på KRAMI (ett samarbete mellan Arbetsförmedlingen, kommunen och socialtjänsten), KRIS (Kriminellas revansch i samhället) och Arbetsförmedlingen.Vårt syfte med studien är att undersöka vilka metoder som används för att hjälpa de frigivna att hitta och behålla ett arbete. Vi vill även titta på vad orsakerna bakom återfall kan vara och hur våra informanter arbetar för att motverka återfall.Vårt val av teorier är Careership, stigma och Focault's maktteori. Careership förklarar hur ett val baseras på invdividens bakgrund. Stigma är en teori som förklarar hur och varför individer är stigmatiserade. På grund av de uppenbara maktförhållanden mellan samhället och de frigivna har vi även inkluderat en maktteori. Vårt resultat visar att våra informanter inte använder några specifika metoder, det baserar sitt arbete på individen. Resultatet visar även att orsakerna till återfall är många och kan inte generaliseras. Vi kan även se att våra informanter arbetar hårt för att motverka återfall men ibland tar statens makt över.This study highlights the work of two different authorities and one organisation working with released prisoners wanting a change. Relapse is a common problem, 44 percent of all released men in Sweden relapse within three years. A lack of endurance and low self-esteem are two of the main reasons for a relapse. We have performed a qualitative study based on the information from three informants working at KRAMI (a cooperation between the Swedish employment agency, the local municipality and the social service) KRIS (criminal’s revenge in society) and Arbetsförmedlingen (the Swedish employment agency).Our vision with this study is to explore the methods that are being used to find a workplace and keep it for the released prisoners. We also want to look in to the reasons for relapse and investigate what our informants are doing to counteract it, this is also our questions of issue.Our theories of choice are Careership, stigma and Foucault’s power theory. Careership aims to explain how personal decisions are made based on background. Stigma is a theory explaining how and why people are stigmatized. Due to the obvious power relations between the society and the released prisoner we also choose to include a power theory. Our findings show that our informants do not use any specific methods, it is all based on the individual. The result also show that the reasons for relapse are many and they can’t be universalized. We can also see that although our informants work hard to counteract relapse sometimes the rules are against them.

Texte intégralRésumé :
This thesis is investigative work into the properties of a recently defined family of graded algebras, which we call VV algebras. These algebras were defined by Varagnolo and Vasserot. We compare categories of modules over KLR algebras with categories of modules over VV algebras, establishing various Morita equivalences. Using these Morita equivalences we are able to prove several properties of certain classes of VV algebras such as affine cellularity and affine quasi-heredity. We also include a discussion about the problems encountered when trying to define finite-dimensional quotients of these algebras. Finally, in certain settings, we show how to define these quotients and explain how they relate to cyclotomic KLR algebras.

Texte intégralRésumé :
A ocorrência da redução biológica do sulfato resulta na formação de um produto indesejado, o sulfeto de hidrogênio, que pode ser removido sob condições limitadas de oxigênio. Os fatores que podem afetar a oxidação do sulfeto não estão bem elucidados e o processo de microaeração é pouco utilizado devido a limitações tecnológicas. Desta forma a oxidação química e bioquímica do sulfeto foi estudada em duas configurações de reatores que utilizam membrana polimérica porosa (membrana de silicone) como alternativa para microaeração. As configurações apresentam duas formas de microaeração, por pressão interna (Reator de membrana Submersa-RMS) e outra externa (Reator de Membrana Externa-RME) com aeração por troca atmosférica. Foram realizados ensaios de transferência de massa para determinação do coeficiente volumétrico global de transferência (KLa). Os resultados médios obtidos para o KLa foram de 0,10 h-1 para o RMS e 0,154 h-1 para o RME, confirmando a microaeração do meio. Os reatores foram operados a fim de avaliar a oxidação do sulfeto a enxofre elementar por via química e bioquímica em diferentes faixas de pH, pressão (para o RMS) e velocidade no interior da membrana (para o RME) por meio de planejamento fatorial. A oxidação química apresentou alta conversão do sulfeto a enxofre com percentual médio de 91,3% no RMS e 79,2% no RME e percentual médio de conversão a sulfato de 2,3% no RMS e 15,7% no RME. A oxidação bioquímica no RME apresentou valores médios de conversão de sulfeto a enxofre de 41,6% e de 52,8% para a conversão a sulfato. A oxidação de efluente de reator sulfetogênico também foi avaliada atingiu valores médios de 48,7% para a conversão a enxofre elementar 46,7% para a conversão de sulfeto a sulfato. O estudo das variáveis demonstrou que a variável que influenciou a oxidação foi o pH. A configuraçõa RMS apresentou problemas operacionais inviabilizando seu uso. O uso de membranas apresentou viabilidade de controle da microaeração através das variáveis operacionais, raio e espessura da membrana. Desta forma, devido à viabilidade operacional e os resultados obtidos, as configurações se mostraram uma alternativa viável a conversão do sulfeto a enxofre elementar.The occurrence of biological sulfate reduction results in the formation of unwanted hydrogen sulfide, which can be removal under oxygen-limiting conditions. Detailed knowledge of this process remains unclear and the micro aeration process was prevented by technological limitations. For these reasons, the chemical and biological oxidation of sulfide was studied in two configurations of reactors using porous polymer membrane (silicon membrane) as an alternative to micro aeration. The configurations present two forms of micro-aeration by internal pressure (Submerged Membrane Reactor- SMR) and an external one (External Membrane Reactor EMR) with aeration by air exchange. The micro aeration was evaluated through the global oxygen mass transfer coefficient (KLa). The average results obtained for KLa were 0.10 h-1 for SMR and 0.154 h-1 for EMR, confirming the micro aeration. The settings were operated to evaluate the chemical and biochemical oxidation of sulfide to elemental sulfur by different variables: pH, pressure (for SMR) and flow/membrane area (for EMR) through factorial design. The chemical oxidation showed high sulfide conversion to sulfur, with mean value of 91.3% in SMR and 79.2% in EMR and conversion to sulfate of 2.3% in SMR and 15.7% in EMR. The biochemical oxidation in EMR showed mean values of sulfide conversion to sulfur of 41.6% and 52.8% for sulfate. The oxidation of sulfidogenic reactor effluent was evaluated and obtained mean values of 48.7% for conversion to elemental sulfur and 46.7% to sulfate. The variable studies showed that the variable pH is significantly for sulfide oxidation. The SMR presented operational problems invalidating their use. The use of membranes, showed a high viability due to its ability to micro aeration especially because of the operating variables, radius and membrane thickness. In general the reactors were efficient due the low sulfate yields. Thus the reactors proved are viable settings to the conversion of sulfide to elemental sulfur.

Texte intégralRésumé :
Denna studie har utförts med bas i frågeställningen huruvida rosa brus kan nyttjas för att replikera den övergripande ljuddynamik som förekommer inom kli-inriktade ASMR-verk med hänseende till envelope-egenskaper samt övergripande frekvensregister och hur den akustiska karaktären av en sådan ljudartefakt kan komma att uppfattas av ett antal respondenter. Tidigare forskning inom ASMR har jämförts med auditivt inriktad litteratur för att styrka relevansen av denna sortens studie varpå ytterligare framtida forskningsutsikter har spekulerats kring. Angreppsmetoden har grundats i användandet av en noise gate-teknik med fokus på side chain-kompression samt en vocoder för replikerandet av den ljuddynamik som har inhämtats från ett kli-inriktat ASMR-verk. Ljudtekniska data för designen av artefakten införskaffades med hjälp av spektrogramanalyser och kvalitativa intervjuer stod till grund för experimentets utförande. Studieresultaten visade huvudsakligen på att rosa brus sannolikt besitter en god förmåga att approximera kli-ljud i det tekniska sammanhang som har studerats och därmed inge behag hos en lyssnare. Även övergångar mellan distinkt olika ljudsegment av denna typ visade sig besitta mycket goda möjligheter att inge behag.

Texte intégralRésumé :
Wood is a material whose use in constructions has increased in modern times. However, wood is a complex material that needs to be further explored to increase the understanding of its properties. The purpose of this work is to study two positions for attaching a balcony railing regarding different direction of the fibers in the wood. More in-depth this study focuses on identifying the influence of position and fibers on the moment capacity and stiffness. This study concerns unevenly distributed compressive loads perpendicular to the grain of the CLT specimen. Forces that occur on a balcony railing causes a bending moment, which is non-linearly distributed in the contact area between the steel plate and the CLT. The study is performed through experimental tests in a laboratory. Deformations are measured using measuring instruments. The measurements results are analyzed to determine moment capacity and stiffness for the different loading configurations. The conditions for the load vary between across and along the fiber orientation of the top layer of the CLT specimen. The results show that loading configurations with the steel plate attached at the edge of the CLT specimen gives higher moment capacity and stiffness in comparison with connections mounted in the corner. Furthermore, the results also shows that the capacity and stiffness depend on the orientation of the fibers in the CLT deck-layer.

ITC/USA 2013 Conference Proceedings / The Forty-Ninth Annual International Telemetering Conference and Technical Exhibition / October 21-24, 2013 / Bally's Hotel & Convention Center, Las Vegas, NVIn our first installment, analog and HD video terms were compared. It was shown that resolution is three-dimensional in HD. High HD data rates force the use of video compression in order to transport video. Compression compromises video detail and introduces latency. Latency affects the overlay of time critical measurements. It is therefore important to time stamp at the source. In this volume, the focus is on the key regions of the HD video frame and metadata. SMPTE specifications are the foundation on which MISB builds its use of metadata. It will be shown that only two KLV packets can hold all TSPI and calibration data with frame-by-frame updates. This capacity is new in HD. Metadata is permanently merged with images and the time that both were collected. We show how employing the KLV metadata packet can result in a single video record where picture taking are all in lockstep. Using KLV metadata enables one to record clean video while retaining the ability to place crosshairs and data during playback.

Texte intégralRésumé :
The CKM matrix element |Vus| can be extracted from the experimental measurement of semileptonic K → π decays and theoretical input for the corresponding vector form factor in QCD. The thesis performs a major improvement of the RBC/UKQCD programme to calculate Kl3 form factor in Nf = 2+1 Lattice QCD using domain wall fermions. We use data from several lattice spacings and dfferent quark masses with lightest pion mass of about 170MeV. Systematic error corresponding to interpolation in the momentum transfer is avoided using partially twisted boundary conditions. Using simulated quark masses near the physical point, reduce the systematic error due to the mass extrapolation. This work explores different kinematic arrangements of pion and Kaon momenta for twisted boundary conditions. This thesis proposes a new ansatz for mass extrapolation. Analysing three sets of simulation data allows for a detailed study of systematic effects leading to the prediction f+kπ (0) = 0:9671(17)(+18-46), where the first error is statistical and the second error systematic. The result allows us to extract the CKM matrix element |Vus| = 0:2237(+13-8) and confirm unitarity of the first row CKM matrix in the Standard Model. Also in this thesis, we discuss porting of Clover Lattice fermion action to Blue Gene-Q architecture. Clover action achieves maximum efficiency of 29.1% for single precision with good weak scaling. Strong scaling shows local volume dependency. In a study of different iterative solvers for Domain Wall Fermion action (DWF), we find that Modified Conjugate Residual(MCR) and Multishift MCR as the most efficient solver compared to CG and GCR. A new probing technique for estimating the diagonal of the inverse Dirac operator in Lattice QCD is introduced and this method is found to be closer to the exact solution than stochastic methods.

This thesis consists of a detailed study of alternating quiver Hecke algebras, which are alternating analogues of quiver Hecke algebras as defined by Khovanov-Lauda and Rouquier. The main theorem gives an isomorphism between alternating quiver Hecke algebras and alternating Hecke algebras, as introduced by Mitsuhashi, in the style of Brundan and Kleshchev, provided the quantum characteristic is odd. A proof is obtained by adapting recent methods of Hu and Mathas, which rely on seminormal forms and coefficient systems. A presentation for alternating quiver Hecke algebras by generators and relations, reminiscent of the KLR presentation for Hecke algebras, is also given. Finally, some steps are taken towards discussing the representation theoretic consequences of the results.

Texte intégralRésumé :
Cette thèse apporte un éclairage complémentaire dans l'étude de la phase d'intégration post-fusion en analysant les processus d'identification des employés au nouveau groupe issu de la fusion. L'identification organisationnelle est reconnue pour son influence dans le fonctionnement organisationnel et plus particulièrement sur l'engagement des salariés. L'engagement des salariés est déterminant dans la réussite de la coopération lors de la fusion. L'objet de recherche de ce travail doctoral est la transition identitaire vécue par les employés suite à une fusion. Les individus ayant une identification duale, c'est-à-dire les individus capables de mobiliser plusieurs identités sont plus à l'aise avec le changement. Cette thèse examine deux problématiques: (1) Comment l'identification duale se construit-elle au cours de la transition identitaire vécue par les salariés suite à une fusion ?; (2) Quelle est l'influence de l'identification duale sur l'engagement des salariés ? Cette recherche repose sur des données quantitatives et qualitatives collectées en temps réel auprès de salariés d'Air France et de KLM, soit plus de 3000 questionnaires et 100 entretiens. Le dispositif longitudinal permet d'analyser les réactions des individus six, douze et dix-huit mois après la fusion. Grâce à l'analyse des antécédents et des conséquences de l'identification duale, cette recherche contribue à une meilleure compréhension des transitions identitaires suite dans fusion. Elle propose aux cadres des leviers d'actions peu connus pour améliorer le management du processus d'intégrationThis thesis proposes a complementary vision in the study of the post-merger integration phase by analyzing the processes of identification of the employees to the merger. Organizational identification has an influence on employees' commitment. Employees' commitment is a key factor in the success of the cooperation during the merger. The object of search of this doctoral research is the identity transition lived by the employees following a merger. Individuals having a dual identification, i. E. Individuals able to rely on several identities are more at ease with changing situations. This thesis examines two questions : (1) How does dual identification develop during the identity transition lived by the employees after a merger ?; (2) Which is the influence of the dual identification on employees' commitment? This research analyzes quantitative and qualitative data collected at Air France and KLM, that is to say more than 3000 questionnaires and 100 interviews. The longitudinal design makes it possible to analyze employees' reactions six, twelve and eighteen months after the merger. Thanks to the analysis of the antecedents and consequences of the dual identification, this research contributes to a better understanding of the identity transition after a merger. It proposes to the executives some little known tools to improve the management of the process of integration after a merger

Texte intégralRésumé :
In the society of consumers, consumption has developed into a basic social need where the purchase of clothing has become a proof of identity, gender and social status. For men, the interest in clothing consumption and appearance has become more accepted in recent decades. However, the interest in clothing consumption is still considered a feminine trait. The social sciences’ interest in clothing and consumption is based on human behaviour, where clothing and other consumed goods affect how individuals understand themselves and their social environment. For men, clothing is a tool that constructs masculinity and male status. The regulations for what types of clothes and colours that are acceptable for men to wear exist within various sets of norms. Since the body is a key element in masculinity research, clothing and norms become interesting factors in the creation and re-creation of masculinity and male gender. The aim with this study is therefore to contribute with further knowledge about the social factors that affect young Swedish men aged 21-27 regarding clothing and clothing consumption as well as how clothing and clothing consumption are included in the construction and re-construction of gender, masculinity and identity. The study’s theoretical framework is based on Judith Butler’s and Raewyn Connell’s presentation of the concept of gender, Connell’s theory of masculinity and Erving Goffman’s research on identity and self-presentation. The empirical data consists of six semi-structured interviews with men from southern Sweden. The results show that all interviewees have similar experiences regarding how they consume clothes, what kind of clothes they prefer and what they think is and is not acceptable for men to wear. Furthermore, a contradiction emerges where men are forced into a template based on norms and social expectations of how a man should look and act, which the interviewees both relate to and despise. This creates an ambivalence where men are expected to make an effort to look a certain way, and at the same time possess an attitude where they are interpreted as independent individuals who do not care about appearance.

Texte intégralRésumé :
Träbyggande har dokumenterade miljövinster och Sverige är en av världens största exportörer av trämaterial, trots detta har Sverige halkat efter i byggandet av flerfamiljshus med träkonstruktion. Rapportens utgångspunkt har varit att undersöka om det i projekteringsfasen av bostäder byggda med trä finns några hinder för storskaligt byggande. Denna rapport har jämfört två flerbostadshus, där huvuddelen av stommen kommer bestå av KL-trä, för att undersöka hur de två projekten har valt att lösa brand- och akustikkraven. KL-trä står för korslimmat massivträ och är element i tre, fem, sju eller fler skikt som kan användas som stommaterial vid byggande av flerbostadshus. Tack vare att elementen är korslimmade kan svällning och krympning av materialet förhindras. Vid projektering av ett relativt nytt material som KL-trä, uppstår ett antal problem då kunskapen och erfarenheterna är bristande. Två av de främsta problemen vid projektering av KL-trä är brand- och akustikkraven som finns i Sverige, rapporten kommer gå igenom vad det finns för krav och regler samt hur trä som material förhåller sig till dessa krav. Rapporten har lett fram till ett antal rekommendationer för projektörer av KL-trä. Rekommendationerna bygger på erfarenheter från de två projekten och projektörerna kopplade till dem. Viktiga utgångspunkter vid projekteringen är spännviddernas storlek och att möten mellan bärande element skiljs åt för att undvika flanktransmissioner.Wood construction has its documented environmental benefits and Sweden is one of the world's largest wood products exporters. Despite this, Sweden has lagged behind in the construction of multi-family houses with wood construction. This reports starting point has been to investigate whether in the design phase of housing built with wood, there has been obstacles to large-scale construction. This report has compared two multi-family houses, the bulk of which consists of CLT. It has also set out to investigate how the two projects have chosen to solve fire and acoustics requirements. CLT is a cross-laminated solid wood element in three, five, seven or more layers that can be used as a material for building multi-family homes. The manufacturing process of CLT means that the elements are cross-glued which will prevent any future swelling and shrinkage of the material. When developing a relatively new material like CLT, a number of problems arise as knowledge and experience are inadequate. Two of the main problems in the design of CLT are the fire and acoustics requirements in Sweden, the report will review the requirements for regulations and how wood as material relies on these requirements. This report has led to a number of recommendations for CLT projectors. These recommendations are based on experiences from the two projects and the projectors associated with them. Important starting points for the design are the size of the span and that supporting elements are separated to avoid flange transmissions.

Texte intégralRésumé :
På Käppalaverket i Stockholm står luftningen av de biologiska bassängerna för omkring en femtedel av verkets totala elenergiförbrukning. I ett försök att minska energikostnaden utvärderades under hösten 2010 nya metoder för luftflödesreglering på verket. Grundtanken var att styra luftflödet efter medelvärdet på utgående ammoniumkoncentration under en längre tid, istället för som idag efter momentana värden. Ett vanligt sätt att styra luftflöden på reningsverk idag är att använda återkoppling från utgående ammoniumkoncentration, vilket syftar till att alltid hålla den utgående koncentrationen vid ett valt börvärde. Lagstiftade gränsvärden på ammonium avser dock normalt medelvärden över en längre tid, såsom kvartal eller år. Istället för att anpassa luftflödet efter den inkommande belastningen är det därför möjligt att hålla luftflödet relativt konstant medan istället den utgående koncentrationen tillåts variera. I denna studie visades en energibesparing kunna erhållas om luftflödets variation reduceras. Två strategier utvärderades i vilka luftflödet respektive syrehalten hölls så konstant som möjligt. Dessa jämfördes med den idag använda styrstrategin på Käppalaverket, i vilken luftflödet anpassas efter den inkommande belastningen genom återkoppling. Studien inkluderade både simuleringar i modellen Benchmark Simulation Model no. 1 och fullskaleförsök på Käppalaverket. I både simuleringar och fullskaleförsök resulterade de två utvärderade strategierna i en lägre luftförbrukning per reningsgrad än den idag använda återkopplingsstrategin. I fullskaleförsöken erhölls en luftflödesreduktion på 11 % då luftflödet hölls konstant och 15 % då syrehalten hölls konstant. Båda strategierna genererade dock en kraftigt varierande utgående ammoniumkoncentration. Variationerna var störst då luftflödet hölls konstant och korrelerade inte med den dygnsbaserade belastningsprofilen. Sammanfattningsvis visade studien att en reducering av luftflödets variation resulterar i en lägre luftförbrukning men också i en ökad instabilitet. En konstant syrehalt gav en större energivinst och även en stabilare ammoniumreduktion än ett konstant luftflöde, varför denna metod har störst potential till vidare implementering i fullskala.The aeration of the bioreactors is responsible for one fifth of the energy consumption at the Käppala wastewater treatment plant (WWTP) in Stockholm. In this report, new methods for aeration control were evaluated in order to reduce the energy costs at the plant. The main idea was to control the effluent ammonia concentration in terms of mean values instead of momentary values. A quite common approach for aeration control is to use feedback from the effluent ammonia concentration, thus aiming to keep the effluent concentration consistently at a certain set point. However, discharge limits normally refer to mean values over longer periods of time, such as months or years. Instead of adjusting the airflow to the incoming load it is therefore possible the keep the airflow fairly constant while allowing a fluctuating effluent concentration. In this paper, it was shown that by reducing the variation of the airflow, energy could be saved. Two methods were evaluated in which the airflow and oxygen concentration respectively was held constant. These methods were compared to the control strategy used today at the Käppala WWTP, where feedback control adjusts the airflow to the influent load. The study consisted of simulations with the Benchmark simulation model no. 1 (BSM1) as well as full scale experiments at the Käppala WWTP. Both the simulations and full scale experiments showed a reduced aeration per nutrient removal for the evaluated methods. In full scale, the total airflow reduction was 11 % when the airflow was held constant and 15 % when the oxygen concentration was held constant. However, the methods resulted in large variations of the effluent ammonia concentration, which did not correlate to the daily influent load. The variations were especially large when the airflow was held constant. In summary, this study showed that a reduced airflow variation results in lower aeration costs but also less stability. A constant oxygen concentration required less aeration and provided a more stable degree of ammonia removal than a constant airflow. For this reason, aeration control with a constant oxygen concentration has the best potential for further use at the Käppala WWTP.

Previous issue date: 2006-02-24The continuing demand for high performance and low cost electrocardiogram processing systems have required the elaboration of even more efficient and reliable ECG compression techniques. The objective of this work is to evaluate the performance of an electrocardiogram (ECG) compression algorithm based on independent components analysis (ICA). To each of the ECG signal we processed, using ICA, vectorial subspaces composed of its basis functions were obtained, for the signal can be expressed as a linear combination of them. The ECG signal was subdivided into m fixed length windows, and each of them was projected in the subspace, resulting in a vector w of coefficients for each window. A simple quantization process was performed over the m vectors w, according to defined levels of quantization, each one generating different levels of reconstruction error. It was observed that the storage of the coefficients implies the use of less space in memory in comparison to that one used by the corresponding windows of the electrocardiogram signal. The reconstruction error measure traditionally used, the percent root mean-square difference (PRD), was used into the evaluation of the algorithm. The results had been compared with those obtained using the Karhunen Lo´eve transform (KLT).
A demanda contınua de por sistemas de processamento de eletrocardiogramas de alto desempenho e baixo custo tem exigido a elaboração de técnicas de compressão de ECG cada vez mais eficientes e confiáveis. O objetivo deste trabalho é avaliar o desempenho de um algoritmo baseado em análise de componentes independentes (ICA) para a compressão de eletrocardiogramas (ECGs). Para cada um dos sinais de ECG utilizados foram obtidos, através de ICA, subespaços vetoriais construıdos a partir de suas funções base, pois o sinal pode ser expresso como uma combinação linear destas. O sinal de ECG foi subdividido em m janelas de comprimento fixo, e cada uma delas foi projetada no subespaço, resultando em um vetor w de coeficientes para cada janela. Um processo de quantização simples foi executado para os m vetores w, segundo nıveis de quantização definidos, cada um gerando diferentes nıveis de erro de reconstrução. Foi observado que o armazenamento dos coeficientes implica na utilização de um menor espaço em memória em comparação àquele utilizado pelas janelas correspondentes do sinal de eletrocardiograma. A medida tradicionalmente utilizada de erro de reconstrução, diferença média quadrática percentual (PRD), foi empregada para a avaliação do algoritmo. Os resultados foram comparados àqueles obtidos utilizando a transformada de Karhunen Loeve (KLT).
