Nаука о књижевности - усмена књижевност / The literary science - The oral literature

Првобитни циљ овог истраживања био је показати да епско време не мора функционисати као искључиво као „затворено“, нити заузимати „острвски положај“ у односу на друге епохе, како се то обично сматрало, при неоправданој аналогији српске епике и руских биљина. Основна метода овог истраживања је семиотичка, а када се истраживање укрштало с научним, лингвистичким, књижевнонаучним, антрополошким, и другим сазнањима (различитим методолошким полазиштима), неминовно је попримало интердосциплинарни карактер и водило је ка методолошком плурализму. Предмет истраживања био је размотрити како се време у песми (наративно време) конституише у поређењу с реално постојећим (историјским, тј. објективним) временом, као и то како оно функционише на равни биографског времена лика, одређеног пре свега социокултурним реалијама друштва у коме варијанта егзистира, везаним за различите узрасне идентитете. Почетна тачка од које се даље самерава биолошко и социјално време је рођење јунака, које је, по правилу, несвакидашње, као, уосталом, и његово порекло. Детињство траје сразмерно кратко, а превазилажење лиминалног статуса детета остварује се првим подвигом, односно јуначком женидбом, чиме се јунаку адолесценту обезбеђује нови статус – младог ратника. Када једном освоји статус ратника, главни јунак остатак живота проводи у његовом сталном потврђивању и доказивању, из једног подвига у други. Зрело доба, стога, функционише као немаркирани (уобичајени) узрасни идентитет јунака. Предавањем јуначких атрибута (коња и оружја) сину, јунак се одриче свог статуса и прелази у категорију старих лица. Излазак из ратничког статуса остварује се на два начина – променом делокруга – уласком у делокруг саветника (мудраца), или одласком у смрт, при чему ће необичном јунаку, саобразно сижеима песама о смрти јунака, одговарати „необична“ смрт. Ограничена рођењем и смрћу, биографија епског јунака, у конкретном сижеу, актуализоваће један од (обично најважнијих) тренутака из живота лика (први сукоб, женидбу и сл), плетући око ове тачке временску арматуру песме...

▼ The classical n-bugs problem has attracted considerable attention from researchers. This problem stems from the study of movement of a group of animals. In the context of multi- agent systems the problem has been modelled as cyclic pursuit. Under this paradigm, every agent, indexed i, chases its unique leader, agent i + 1 (modulo n), with n being the total number of agents. In the existing literature, cyclic pursuit has been studied for homogeneous agents where each agent’s velocity is proportional to the distance separating it from its leader and is directed along the line joining it to its leader. The constant of proportionality, initially chosen to be the same for all the agents, resulted in consensus in position, without the need for any centralized controller. Later, the constant of proportionality, alternately called the gain, was allowed to be heterogeneous and positional consensus was still achieved. Moreover, it was shown that the point of convergence, where the agents rendezvous, could be chosen at will, except for some diagnostic cases. In this thesis, besides admitting heterogeneous gains, the agents are assumed to pursue their respective leaders with an angle of deviation from the line joining them to their corresponding leaders. This expands the reachability set (set of points where the agents can rendezvous) for the system of agents to include points that were hitherto unreachable. Sufficient conditions for stability of such systems have been derived in this thesis. Detailed analysis of the reachability set has also been carried out. Some researchers have also investigated hierarchical cyclic pursuit, where there are multiple levels of pursuit. For instance, in the two level hierarchical pursuit, the agents are divided into m groups of n agents each, where each agent in a group chases its leader within the group as well as a similarly indexed agent in its leading group. Thus, groups of agents are also in cyclic pursuit. So far, only homogeneous gains were considered under this paradigm. The present thesis admits heterogeneous gains and establishes necessary and sufficient conditions for the stability of heterogeneous hierarchical cyclic pursuit, that generalize existing results. Reachable sets are also derived for this case. It is proved that the existing results can be derived as special cases of the ones considered in this thesis. As an extension to a realistic application, the importance of expansion in reachable set vis-a`-vis capturing a moving target is highlighted in this thesis. It has been shown that if the target’s initial position is reachable, then using a control law proposed in the thesis, the target can be captured. This control law is essentially an augmented cyclic pursuit law with the target’s velocity information fed to each agent in addition to the conventional cyclic pursuit command. Analysis has been carried out for agents with double integrator dynamics as well. A control law in conjunction with an algorithm is proposed that helps ensure global reachability of agents, with double… Advisors/Committee Members: Ghose, Debasish (advisor).

▼ The previous goal of this research was to show that epic time does not have to function exclusively as “closed”, nor to hold “the island position” put against the other epochs, the opinion that prevailed in recent times when Serbian folk epic and Russian epic folk songs (byliny) were compared. The main method of this research is semiological, but when the reseached mingled with scientific, linguistic, literary scientific, antropological and other types of knowledge (different methodological points of departure), it inevitably took interdisciplinary character and lead to methodological pluralism. The main point of this research was to figure out the way in which time in a poetic narrative (narrative time) relates to the real (historical, i.e., objective) time, as well as the way it functions as biographical time of the character determined by sociocultural facts in which a variation exists, connected to different age identities. The starting point from which biological and social time measures is the birth of a hero. His birth as well as his origin is highly unusual. The period of childhood lasts relatively shortly. The liminal phase of the child is abandoned with his first achievement, or heroic marriage. The adolescent then acquires a new status – status of young warrior. Once the status of warrior is acquired, the hero spends the rest of his life in constant confirmation, more with every battle. Adulthood, therefore, functions as an unmarked (usual) maturity identity of the hero. By handing down his heroic symbols (the horse and the weapon) to his son, the hero renounces his status and becomes old. His leaving is accomplished in two ways – by changing the surrounding – becoming an advisor or a sage – or by dying whereby the unusual hero, in compliance with the the plots of the hero's death poems, faces unusual death. Bounded by birth and death, biography of an epic hero in a particular plot actualizes one of the (usually most important) moments of his life (the first conflict, marriage, etc.) weaving around this point the temporal foundation of the poem. Time in oral folk epic creates a very compound system of relations – both in extra-poetic reality and within the “epic time”. The first type of relationship is achieved with breaking through the barrier of the (recent) past in chronicle modeled poems, by introducing the narrators alter ego, a narrator – participant (i.e., by introducing the internal perspective of the text). Unlike the previous – mobility (before all – mutual approximation) of different biographical times of the characters who share mutual past – enabled different characters whose historical prototypes are severed by several centuries to act together. Appearance of particular characters in particular plots could be conditioned by historical setting, as well as by the fund of knowledge in the tradition, which create the role (sphere of interest) that the hero is going to play. Independently on the category of character, time in the poem reflects the…

Dans cette thèse, nous nous sommes attaqués au problème de séparation aveugle de mélanges linéaires de sources ayant des propriétés de cyclo-stationnarité. Trois applications ont été abordées à savoir : télécommunications, vibrations mécaniques et biomécaniques. Dans un premier temps, deux nouvelles méthodes ont été proposées, la première a pour but de séparer aveuglement des sources cyclo-stationnaires partageant une ou plusieurs fréquences cycliques inconnues. Elle combine la diagonalisation conjointe à un nouveau détecteur de points utiles (retard-fréquence cyclique) permettant de composer l’ensemble de matrices de corrélation cyclique devant être diagonalisées conjointement. Quant à la deuxième méthode, elle vise à identifier la matrice de mélange de sources cyclostationnaires de fréquences cycliques inconnues et différentes. L’identification commence par une étape de détection des matrices de rang un, puis décompose en éléments propres le produit de matrices sélectionnées, enfin une méthode de regroupement hiérarchique restitue les colonnes de notre matrice recherchée. Les deux solutions ont été appliquées aux signaux de télécommunications. Dans un second temps, nous avons appliqué d’abord la première méthode proposée sur des signaux mécaniques issus d’un banc de roulements défaillants afin de tester son aptitude à séparer les sources. Ensuite, nous avons proposé une approche qui s’appuie sur l’analyse en composantes parcimonieuses pour séparer les composantes de la force de réaction au sol ayant des propriétés cyclo-stationnaires à l’ordre 1 et 2

In this thesis, we have tackled the problem of blind separation of linear mixtures of sources with cyclo-stationarity properties. Three applications were studied : telecommunications, mechanical vibrations and biomechanics. First, two new methods have been proposed, the first one aims to blindly separate cyclo-stationary sources sharing one or more unknown cyclic frequencies. It combines the joint diagonalization with a new useful point detector (time lag-cyclic frequency) to compose the set of cyclic correlation matrices to be jointly diagonalized. As for the second method, it aims to identify the mixture matrix of cyclo-stationary sources of unknown and different cyclic frequencies. The identification begins with a step of detecting the matrices of rank one, then the product of selected matrices is decomposed into eigen-elements, and finally a hierarchical regrouping method returns the columns of our sought matrix. Both solutions have been applied to telecommunications signals. In a second step, we first applied the first proposed method on mechanical signals coming from a bank of faulty bearings in order to test its ability to separate the sources. Next, we proposed an approach based on sparse component analysis to separate the components of the ground reaction force with cyclo-stationary properties at order 1 and 2

▼ One of the main focus of research on multi-agent systems is that of coordination in a group of agents to solve problems that are beyond the capability of a single agent. Each agent in the multi-agent system has limited capacity and/or knowledge which makes coordination a challenging task. Applications of multi-agent systems in space and ocean exploration, military surveillance and rescue missions, require the agents to achieve some consensus in their motion. The consensus has to be achieved and maintained without a centralized controller. Multi-agent system research borrows ideas from the biological world where such motion consensus strategies can be found in the flocking of birds, schooling of fishes, and colony of ants. One such classes of strategies are the cyclic pursuit strategies which mimic the behavior of dogs, birds, ants, or beetles, where one agent pursues another in a cyclic manner, and are commonly referred to as the `bugs' problem, In the literature, cyclic pursuit laws have been applied to a swarm of homogenous agents, where there exists a predefined cyclic connection between agents and each agent follows its predecessor. At equilibrium, the agents reach consensus in relative positions. Equilibrium formation, convergence, rate of convergence, and stability are some of the aspects that have been studied under cyclic pursuit. In this thesis, the notion of cyclic pursuit has been generalized. In cyclic pursuit, usually agents are homogenous in the sense of having identical speeds and controller gains where an agent has an unique predecessor whom it follows. This is defined as the basic cyclic pursuit (BCP) and the sequence of connection among the agents is defined as the Pursuit sequence (PS). We first generalize this system by assuming heterogeneous speed and controller gains. Then, we consider a strategy where an agent can follow a weighted centroid of a group of other agents instead of a single agent. This is called centroidal cyclic pursuit (CCP). In CCP, the set of weights used by the agents are assumed to be the same. We generalize this further by considering the set of weights adopted by each agent to be different. This defines a generalized centroidal cyclic pursuit (GCCP). The behavior of the agents under BCP, CCP and GCCP are studied in this thesis. We show that a group of holonomic agents, under the cyclic pursuit laws ¡ BCP, CCP and GCCP ¡ can be represented as a linear system. The stability of this system is shown to depend on the gains of the agents. A stable system leads to a rendezvous of the agents. The point of rendezvous, also called the reachable point, is a function of the gains. In this thesis, the conditions for stability of the heterogeneous system of agents in cyclic pursuit are obtained. Also, the reachable point is obtained as a function of the controller gains. The reachable set, which is a region in space where rendezvous can occur, given the initial positions of the agents, are determined and a procedure is proposed for calculating the gains of the agents for rendezvous… Advisors/Committee Members: Ghose, Debasish (advisor).

A calcopirita (CuFeS2) é o sulfeto de cobre mais abundante na natureza e pertence ao grupo mais explorado de minerais de cobre, representando cerca de 70% do total de cobre disponível. O objetivo deste trabalho foi estudar as principais etapas de oxidação e redução de calcopirita sólida em solução salina ácida utilizada em biolixiviação usando técnicas eletroquímicas e caracterizar morfológica, química e fisicamente a superfície do eletrodo, a fim de atribuir os diferentes eventos eletroquímicos. Para os estudos eletroquímicos foram utilizadas as técnicas: voltametria linear (LSV) e voltametria cíclica (CV), cronoamperometria (CA), espectroscopia de impedância eletroquímica (EIS) em diferentes intervalos de potencial ou a diferentes valores de potenciais. A caracterização das diferentes espécies formadas em cada condição de potencial ou experimental foi realizada por meio de microscopia eletrônica de varredura (SEM) e microanálise (EDS), difração de raios X (XRD), com o propósito de investigar os fenômenos que ocorrem na superfície da calcopirita sólida e propor possíveis reações envolvidas na lixiviação química. Após os diferentes ensaios eletroquímicos, foi realizada a análise do eletrólito por espectrometria de absorção atômica (AAS) para determinar as concentrações dos íons ferro e cobre em solução. Os voltamogramas cíclicos mostraram mais de 15 picos de corrente diferentes no intervalo de potencial entre +1,5 e -1,5 V/Ag|AgCl|KCl3mol/L. Nas voltametrias cíclicas de baixa velocidade e no sentido de potencial (E) positivo do que o de circuito aberto (EOCP), a análise da superfície apresentou uma camada rica em sulfeto de cobre e a AAS detectou íons cobre e ferro em solução, enquanto que na varredura no sentido de E < EOCP a superfície indicou a presença de um filme rico em enxofre e a AAS encontrou maiores concentrações de íons de ferro e cobre em solução. As voltametrias lineares até +0,65 V/Ag|AgCl|KCl3mol/L seguidas de análise da superfície e da solução mostraram que o produto formado pode ser fosfato de ferro ou polissulfetos e para potenciais superiores predomina a formação de enxofre elementar. Os diagramas de impedância eletroquímica mostraram que quanto maior era o potencial das voltametrias lineares menores eram os valores de resistência do material. Para cronoamperometria de 12 h os resultados mostraram que até 0,45 V não se detectou a formação…

▼ Vias férreas balastradas são uma das principais estruturas nas quais circulam os comboios de alta velocidade. A grande velocidade de circulação destes veículos induz vibrações acrescidas na via-férrea e estruturas circundantes, que podem afetar a eficácia e custos de manutenção da via. Consequentemente é cada vez maior a procura de meios precisos de previsão da resposta de vias férreas à passagem de comboios de alta velocidade. As simulações numéricas são bastante eficientes para prever a resposta da via e a propagação de ondas no solo. No entanto algumas simplificações numéricas impedem muitas vezes estes modelos de permitir análises mais detalhadas sobre a resposta tridimensional da via e o comportamento não-linear do balastro e do solo de fundação. Este trabalho contribui para aprofundar o conhecimento existente do comportamento de vias férreas através de análises 3D não-lineares e do estudo da importância do comportamento não-linear dos materiais nas previsões numéricas. A primeira parte do trabalho visa essencialmente o estudo do comportamento plastodinâmico das vias férreas e da precisão numérica de malhas em Elementos Finitos 3D para a simulação das vias. As vantagens e desvantagens das simulações em Elementos Finitos 3D são discutidas e são identificados os propósitos para os quais estas simulações são mais adequadas. A segunda parte do trabalho foca-se no estudo da resposta não-linear de balastro e solo de fundação através de simulações no domínio do tempo. O estudo do comportamento do balastro é feito através de um modelo constitutivo no qual a consideração em separado de superfícies de cedência e da variação do módulo de Young com a tensão média permitiu identificar a influência de cada na resposta da via. A análise tridimensional permitiu também estudar a distribuição de tensões e deformações na direção transversal e longitudinal da via, facultando uma análise do diferente comportamento de balastro debaixo de uma travessa e de balastro situado entre duas travessas. O estudo do comportamento não-linear do solo é feito através de um modelo não-linear cíclico que foi implementado no software de Elementos Finitos. Isto permitiu o estudo da distribuição espacial e temporal da degradação da rigidez que o solo sofre durante a passagem de um eixo de um comboio. Finalmente a simulação integrada do comportamento não-linear do solo e do balastro permitiu compreender a importância do comportamento não-linear em função da velocidade de circulação do comboio.

▼ Error-control codes provide a mechanism to increase the reliability of digital data being processed, transmitted, or stored under noisy conditions. Cyclic codes constitute an important class of error-control code, offering powerful error detection and correction capabilities. They can easily be generated and verified in hardware, which makes them particularly well suited to the practical use as error detecting codes.A cyclic code is based on a generator polynomial which determines its properties including the specific error detection strength. The optimal choice of polynomial depends on many factors that may be influenced by the underlying application. It is therefore advantageous to employ programmable cyclic code hardware that allows a flexible choice of polynomial to be applied to different requirements. A novel method is presented in this thesis to realise programmable cyclic code circuits that are fast, energy-efficient and minimise implementation resources.It can be shown that the correction of a single-bit error on the basis of a cyclic code is equivalent to the solution of an instance of the discrete logarithm problem. A new approach is proposed for computing discrete logarithms; this leads to a generic deterministic algorithm for analysed group orders that equal Mersenne numbers with an exponent of a power of two. The algorithm exhibits a worst-case runtime in the order of the square root of the group order and constant space requirements.This thesis establishes new relationships for finite fields that are represented as the polynomial ring over the binary field modulo a primitive polynomial. With a subset of these properties, a novel approach is developed for the solution of the discrete logarithm in the multiplicative groups of these fields. This leads to a deterministic algorithm for small group orders that has linear space and linearithmic time requirements in the degree of defining polynomial, enabling an efficient correction of single-bit errors based on the corresponding cyclic codes.

La caractérisation du comportement des matériaux bitumineux est primordiale pour pouvoir dimensionner les structures de chaussées, mais aussi pour prédire de manière plus précise leur durée de vie. En effet, ces matériaux sont soumis à des phénomènes complexes, mécaniques, thermiques, physiques et chimiques qui apparaissent souvent de manière couplée. Devant la complexité des problèmes observés et avec l’apparition des nouveaux matériaux et nouvelles techniques de fabrication, des études avancées de laboratoire et des modélisations rhéologiques sont nécessaires. Les méthodes existantes permettent de caractériser les matériaux en laboratoire grâce à l’utilisation de presses hydrauliques très couteuses. De plus, la plupart de ces essais ne sont pas adaptés à une utilisation directe sur chaussées. Dans cette thèse, un essai dynamique qui repose sur le phénomène de propagation d’onde a été développé pour caractériser les enrobés bitumineux dans le domaine viscoélastique linéaire. Il s’agit d’un essai non destructif, bien moins couteux que les essais existants et qui pourrait à terme s’adapter à une utilisation in-situ. Des méthodes complexes d’analyse inverse de propagation d’ondes en milieu viscoélastique ont été mises au point afin d’obtenir les propriétés thermomécaniques des enrobés bitumineux à partir des signaux mesurés expérimentalement. Les propriétés viscoélastiques linéaires de différents enrobés bitumineux déterminées à partir de l’essai dynamique développé ont été comparées aux résultats obtenus avec des essais cycliques plus conventionnels de traction-compression.

Characterizing the behaviour of bituminous materials is essential for the design of pavement structures and to predict their service life more accurately. Indeed, these materials are subjected to complex phenomenon, mechanical, thermal, physical and chemical that are often coupled. Due to the complexity of the phenomenon observed and with the emergence of new materials and new production techniques, advances laboratories studies and rheological modelling are necessary. With the existing methods, it is possible to characterize the materials in laboratories using expensive hydraulic presses. Moreover, most of these tests cannot be used directly on pavement structures. In this thesis, a dynamic test based on wave propagation was developed to characterize bituminous mixtures in the linear viscoelastic domain. It is a nondestructive test, far less expensive than the existing tests and that could be adapted for in situ measurements. Complex methods of inverse analysis of wave propagation in a viscoelastic medium were developed to obtain the thermomechanical properties of bituminous mixtures from the signals measured experimentally. The linear viscoelastic properties of different mixtures obtained from the developed dynamic test were compared to the results of more conventional cyclic tension-compression tests.

The goal of this work was to simulate the behaviour of ice under cyclic loading. The linear viscoelastic Kelvin, Maxwell and Burgers models were implemented in Matlab by means of The Boltzmann superposition principle. This method was verified using cases which could be represented by analytical solutions. During the extensive sensitivity analysis carried out, it was determined that the ratio n/(f?) influences the shape of the strain response curve in a creep test for all of the models considered in this study. With the knowledge of parameter n/(f?), preliminary conclusion on the result of the test can be drawn. The change of the second modulus is defined by the Kelvin unit which determines the delayed elastic deformations. The time required for these deformations to fully developed is given by 5?2. The changes in the value of the second modulus occurs only before this value is attained. However in linear viscoelastic Burgers model, this change is relatively small . This is because the Maxwell unit in the Burger model has a major influence on the shape of the stress-strain curves. Available literature was used to obtain the input parameters for Burgers model for ice. They were obtained by calibration of the model data with the experimental data presented therein by producing a best fit curve. Since this study utilized a non-linear model to replicate the experimental data, it was also used to compare the results of a linear model with a non-linear model. The region conforming to the delayed elastic deformation was not represented accurately by the linear model. Uniaxial cyclic compression test performed at UNIS was modeled using the linear viscoelastic Burgers model using the scaled down input parameters obtained through calibration with fresh ice creep test to enable their application to this case. The viscoelastic model was unable to completely agree with the findings from the test carried out at UNIS.

▼ The topic of structural damage caused by fires following an earthquake (FFE) has been discussed extensively by many researchers for over a decade in order to bring the two fields closer together in the context of performance based structural engineering. Edinburgh University, Heriot-Watt University, Indian Institute of Technology Roorkee (IIT Roorkee) and Indian Institute of Science initiated a collaboration to study this problem under a UK-India Engineering Research Initiative (UKIERI) funded project. The first construction of a single-storey reinforced concrete frame at IIT Roorkee was completed in summer 2011; this is known as the Roorkee Frame Test 1 throughout this thesis. This thesis presents the modelling of the Roorkee Frame Test 1 using the finite element method and assesses the capability of the numerical methodologies for analysing these two sequential events. Both two and three dimensional finite element models were developed. Beam and shell elements were chosen for the numerical modelling, which was carried out using the general purpose finite element package ABAQUS (version 6.8). The variation in material properties caused by these two types of loading, including strength and stiffness degradation, compressive hardening, tension stiffening, and thermal properties, is implemented in the numerical modelling. Constitutive material calculations are in accordance with EC4 Part 1.1, and all loading is according to IS 1893:2002 Part 1 (Indian Standard). The time-temperature curve used in the analysis is based on data from the test carried out. The behaviour of the Roorkee Frame Test 1 when subjected to monotonic, cyclic lateral loading followed by fire is presented. The capacity of the frame when subjected to lateral loading is examined using a static non-linear pushover method. Incremental lateral loading is applied in a displacement-controlled manner to induce simulated seismic damage in the frame. The capacity curve, hysteresis loops and residual displacements are presented, discussed and compared with the test results. The heat transfer analysis using three dimensional solid elements was also compared against temperature distributions recorded during the Roorkee frame fire test. Based on the smoke layer theory, two emissivity values were defined. In this study, the suitability of numerical modelling using ABAQUS to capture the behaviour of Roorkee frame test is examined. The results from this study show that the 3D ABAQUS model predicted more reliable hysteresis curves compared to the 2D ABAQUS model, but both models estimated the lateral load capacity well. However neither model was able to simulate the pinching effect clearly visible in the hysteresis curves from the test. This was due to noninclusion of the bond slip effect between reinforcing bars and concrete. The residual displacement obtained at the end of the cyclic lateral loading analysis from the 2D ABAQUS model is higher than that seen in the test. However, the result in the 3D ABAQUS model matched the trend obtained in the test. The both…

Mestrado em Engenharia Civil e do Ambiente : Especialização em Estruturas na Escola Superior de Tecnologia e Gestão do Instituto Politécnico de Viana do Castelo

Os pilares ocos de betão armado são usualmente utilizados em obras de arte, quando é necessário que um pilar tenha uma grande altura, mas com uma grande rigidez e um peso reduzido. Estes mesmos pilares têm um comportamento muito semelhante ao de paredes estruturais, portanto os modos de rotura e padrão de danos podem ser associados em ambos os mecanismos de flexão e de corte, onde normalmente o mecanismo de rotura por corte é predominante. Neste contexto, não é simples a definição de danos esperados e é bastante complexo definir um único parâmetro que seja capaz de prever esses comportamentos. Efetuada uma pesquisa foi visto que ainda existem muito poucos estudos sobre o padrão de danos e consequências económicas da reparação e reforço dos danos físicos existente neste tipo de elementos quando submetidos a ações sísmicas. Estas informações são muito importantes quando se equaciona a análise custo-benefício de medidas de prevenção ou reparação dos danos sísmicos segundo um determinado padrão. Portanto, o presente trabalho pretende estabelecer uma estratégia para identificar os Estado Limite de Dano Sísmicos em pilares ocos de betão armado e definir um parâmetro de resposta capaz de traduzir os níveis de dano. Pretende-se também discutir as adequadas estratégicas de reparação e reforço, bem como os seus custos, associados a cada estados limite de dano sísmico. Para este efeito, vários ensaios experimentais realizados no LESE (Laboratório de Engenharia Sísmica e Estrutural) da FEUP (Faculdade de Engenharia da Universidade do Porto) serão analisados, envolvendo o comportamento cíclico de espécimes em escala reduzida, onde será avaliado o padrão de danos e estimados os parâmetros de resposta correspondentes (EDP). Para a determinação dos custos de reparação e reforço será tido em conta o trabalho realizado no projeto PRISE.

Hollow columns of reinforced concrete are usually used in works of art (e.g. Bridges), when it’s required to have a large height, but with a high rigidity and low weight. These same of columns have a very similar behavior to that of structural walls, therefore modes of failure and damage pattern can be associated with both mechanisms bending and shear where usually the shear failure mechanism is predominant. In this context, is not simple to define damage of is quite complex and defining a single parameter that is able to predict such behavior. Conducted a survey it was seen that there are very few studies on the pattern of damage and economic consequences of repair and reinforcement of existing physical damage in such elements when subjected to seismic loads. This information is very important when it equates the cost-benefit analysis of measures to prevent or repair of earthquake damage in a pattern. Therefore, this study aims to establish a strategy to identify the limit states of seismic damage in hollow columns of reinforced…

The present research work involves two different types of polymers which were synthesized under high vacuum conditions with known procedures leading to final materials with molecular and compositional homogeneity (model polymers). Linear diblock copolymers of the PS-b-PB1,2, type, where PS is polystyrene and ΡΒ corresponds to polybutadiene, linear homopolypeptides of tyrosine, the corresponding cyclic architectures, as well as linear diblock and triblock of the A-b-B and A-b-B-b-A types, where Α corresponds to conventional polymer segments [ΡΒ, ΡΙ and PDMS: polydiemthylsiloxane] and B to polypeptide chains like PTyr and PLeu (polytyrosine and polyleucine) respectively. The first set of samples were synthesized in order to modify the PB segments with various organic reactions in to new chains consisting of large side groups per monomeric unit in order to study their change in behavior and its potential applications as sensors due to their electric and thermodynamic properties and their very low surface tension. A very straightforward challenge in the synthesis of polypeptides is their ability to self-assemble in structures that are not existing in natural such materials (proteins). Such polypeptides exhibit identical behavior with block copolymers and therefore can be applied as antifoaming media, membranes and micelles. Actually copolymers exhibiting one segment hydrophilic and the other hydrophobic form micelles and therefore could be used in pharamaceutical applications and in geneticgene technology. In order to verify the homogeneity in composition and molecular weight for all samples and also the successful synthesis it was necessary to make molecular and morphological characterization studies. Specifically, for the molecular characterization size exclusion chromatography (SEC), proton and carbon nuclear magnetic resonance spectroscopy (1H-NMR, 13C-NMR και DEPT 13C-NMR), infrared spectroscopy (IR), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA/DTA) were used leading to very interesting results and observations concerning the successful synthesis of all samples. Scanning electron microscopy (SEM), Transmission electron microscopy (TEM) and small angle X-ray scattering (SAXS) were employed for the morphological characterization.

Cette thèse a pour objectif de proposer une modélisation performante des supercondensateurs à électrodes à base de carbone activé, composants de puissance présents dans un nombre croissant d’applications de stockage d’énergie. La première étape des travaux a consisté à mettre en évidence les phénomènes physico-chimiques, qu’ils soient électrostatiques ou électrochimiques grâce à des essais de caractérisation spécifiques et de vieillissement. L’analyse des résultats associée à la connaissance des matériaux constitutifs a conduit à attribuer le comportement non linéaire du supercondensateur aux phénomènes d’adsorption-désorption (électrosorption) et de diffusion anomale des espèces adsorbées dans le réseau microporeux de l’électrode. La prise en compte de ces phénomènes et de la capacité de double couche a permis de définir un modèle non linéaire fractionnaire dont les paramètres dépendent des grandeurs physico-chimiques de la cellule. La procédure proposée pour l’identification des paramètres du modèle repose sur la réponse en tension du supercondensateur à des profils de charges-décharges. Malgré la simplicité de l’identification, le modèle traduit fidèlement le comportement du supercondensateur soumis à des profils en courant typiques d’applications véhicules électriques et hybrides.

This work aim is an efficient modelling proposal for supercapacitors made of activated carbon electrodes which are power components used in many energy storage applications. In the first part of this study, the purpose is to evidence physico-chemical phenomena, electrostatic or electrochemical as well, thanks to characterization and aging tests. The results analysis combined with materials knowledge leads to suppose that the supercapacitor non linear behavior is due to adsorption-desorption processes and also to anomalous diffusion of adsorbed species into the electrode microporous network. These mechanisms in addition with the double layer capacitor principle allow us to define a non linear fractional model with parameters that depend on physic0-chemical characteristics of the cell. The proposed identification procedure is based on the voltage response to charges-discharge current profiles. In spite of the simplicity of this identification method, the model matches very well the behavior of the supercapacitor under current profiles that are typical of hybrid and electric vehicle applications.

Cette thèse s’intéresse au fonctionnement cyclique multi-produits des ateliers de traitement de surface, et au problème d’ordonnancement associé (HSP), caractérisé par des contraintes fortes et atypiques, dont certaines sont liées aux ressources de transport. Dans le cas de productions en grandes séries, une commande cyclique de ces systèmes est particulièrement adaptée, permettant notamment de réduire la combinatoire de résolution, et sous réserve que les ratios de produits soient connus à l’avance. Notre objectif est de trouver le meilleur ordonnancement des tâches de traitement et de transport en un temps raisonnable. Pour cela, nous proposons une première approche, basée sur un modèle linéaire et une méthode de résolution arborescente de type séparation et évaluation. Nous présentons des modélisations pour différentes extensions du problème dit de base et nous fournissons des exemples illustratifs et des résultats sur des benchmarks. Par la suite et compte tenu de l’analyse de la littérature relative aux ordonnancements cycliques mono-produit et multi-produits, nous proposons tout d’abord une heuristique dédiée au cas multi-produits étudié, et basée sur un algorithme de liste. Avec ce dernier, nous obtenons un ordonnancement cyclique dont le degré du cycle n’est pas fixé au préalable. Enfin, nous présentons une deuxième modélisation approchée sous la forme d’un algorithme génétique pour résoudre un HSP 2-cyclique. Ces différents modèles sont validés par des tests sur des benchmarks de la littérature pour lesquels nous avons obtenus des résultats prometteurs. Nous terminons par une analyse critique des avantages et inconvénients des modèles élaborés et par quelques propositions de perspectives pour ce travail.

In this thesis, we study the Cyclic Hoist Scheduling Problem (CHSP) in automated electroplating lines, when a mass production must be achieved. The CHSP is characterized by specific constraints related to processing and transport resources. To solve it in a multi-parts context, we first elaborate a 2-degree cyclic model and an associated branch and bound algorithm. Then we extend it to more complex configurations. Then, we develop a dedicated heuristic to find a feasible repetitive sequence of hoist moves that minimizes the cycle time, without a priori fixing the cycle degree. Comparisons with existing algorithms are presented to show the efficiency of the proposed heuristic. To reduce the cycle time, we integrate in the general heuristic an algorithm with a set of Minimum Part Set (MPS) configurations’. This one allows us to find the best order in which jobs should be introduced into the line. Finally, we describe a genetic algorithm approach to find a schedule which can reach the optimal 2-cycle. We finally discuss the interest of those various models, based on the promising results obtained and we provide some perspectives which could be explored.

Dans cette thèse, nous nous intéressons principalement à l’étude du fonctionnement cyclique mono-produit des ateliers de traitement de surface. Notre contribution porte sur le problème d’ordonnancement associé connu dans la littérature sous le nom Cyclic Hoist Scheduling Problem (CHSP). L’objet de cette thèse est de proposer des méthodes efficaces pour la résolution des problèmes de traitement de surface dans le cas où les produits à traiter sont du même type. Nous traitons en particulier le cas où le nombre des robots présents sur la ligne est égal à deux, ce qui augmente le nombre des contraintes du problème, sachant que dans le cas mono robot, ce problème a été prouvé NP-Complet. Pour cela, nous proposons une méthode qui combine deux heuristiques et un programme linéaire mixte. Cette méthode permet notamment d’affecter les mouvements de transport à l’un des deux robots tout en gérant les risques de collision entre eux, lorsque la gamme opératoire des produits à traiter suit l’implantation des cuves.Par la suite, nous proposons une extension du modèle au cas de lignes complexes. Enfin, nous étudions le cas d’un fonctionnement mixte, pour lequel il est nécessaire de traiter dans une même installation des produits différents et des rafales de produits identiques. Dans ces conditions, la solution la plus intéressante pour les industriels est de pouvoir alterner des modes de production dynamiques et cycliques. Pour cela, nous proposons une méthode efficace permettant de résoudre le problème d’ordonnancement associé à la phase transitoire relative à ce type de fonctionnement. Elle consiste en particulier à chercher les dates d’entrée au plus tôt des produits. La principale difficulté identifiée consiste ici à passer du mode dynamique au mode cyclique, c’est-à-dire à rejoindre un cycle à partir d’une solution courante donnée, en supposant que ce cycle est connu à priori. Les méthodes élaborées dans les divers cas traités sont validées par des tests sur des benchmarks de la littérature.

In this thesis, our interest is focused on the Cyclic Hoist Scheduling Problem (CHSP) in automated electroplating lines. The aim of this study is to propose an algorithm to solve the two-hoists cyclic scheduling problem. This one consists in finding a repetitive sequence of hoists’ moves, while avoiding collision between the hoists which share a common track. The objective is to minimize the period of this repetitive cycle for single part-type production. This problem was proved to be NP-complete for lines with a single hoist. The fact that two hoists are available on the line increases the number of constraints of the problem. Then we propose a solving method combining two heuristics and a Mixed Integer Linear Program. It enables us to solve both assignment and sequencing problems, while considering spatial constraints related to hoist’moves.Subsequently, we propose an extension of the model which is adapted to complex lines. Finally, our interest is focused on solving a HSP for which it is necessary to treat in the same facility a…

▼ Raman optical activity (ROA) is a powerful probe of the structure and behaviour of biomolecules in aqueous solution for a number of important problems in molecular biology. Although ROA is a very sensitive technique for studying biological samples, it is a very weak effect and the conditions of high concentration and long data collection time required limit its application for a wide range of biological samples. These limitations could possibly be overcome using the principle of surface enhanced Raman scattering (SERS). The combination of ROA with SERS in the form of surface enhanced ROA (SEROA) could be a solution for widening the application of ROA. In the last few years, the generation of reliable SEROA spectra of biomolecules has been problematic due to non-homogenous colloidal systems forming and low signal-to-noise ratios which complicated detection of the true SEROA signal from the analyte. L- and D-enantiomers give full or partially mirror image chiroptical spectra, this property of enantiomers can be employed to prove the chiroptical activity of the SEROA technique. In this thesis we employed a hydrophilic polycarbopol polymer as stabilising media which has led to the first report of mirror image SEROA bands for enantiomeric structures. This new technique of incorporating the hydrogel polymer as a means to stabilise the colloidal system has proven to be reliable in obtaining high quality SEROA spectra of D- and L-enantiomers of ribose and tryptophan. In an extension of the hydrogel-stabilised SEROA work, we also demonstrate that single nanoparticle plasmonic substrate such as silver silica nanotags can enhance the weak ROA effect. These dye tagged silica coated silver nanoparticles have enabled a chiral response to be transmitted from a chiral analyte to the plasmon resonance of an achiral metallic nanostructure. The measurement of mirror image SERROA bands for the two enantiomers of each of ribose and tryptophan was confirmed for this system. The generation of SEROA for both systems was achieved and confirmed SEROA as a new sensitive tool for analysis of biomolecular structure. In a related project, Raman and ROA spectra were measured for adenosine and seven of its derivative ribonucleotides. Both of these spectroscopic techniques are shown to be sensitive to the site and degree of phosphorylation, with a considerable number of marker bands being identified for these ribonucleotides. Moreover, the SERS studies of these ribonucleotides were also performed. The obtained SERS spectra were shown similar features that confirm these analytes interact with the surface in a similar manner, hence limiting the structural sensitivity of this method towards phosphate position. Short dipeptides such as diketopiperazine (DKP) have been investigated during the last decades as both natural and synthetic DKPs have a wide variety of biological activities. Raman and ROA spectra of linear and cyclic dialanine and diserine were measured to charecterize their solution structures. Density functional theory (DFT) calculations were…

▼ This project is a part of a sustained research effort to make houses more affordable and safer. This project seeks to modernize the current prescriptive lateral bracing design of houses to a performance-based design. The aim of this project is to develop a rational holistic model for bracing of cold-formed steel-framed houses. It focuses on the development of the rational testing method and the evaluation procedure for determining the bracing capacity of cold-formed steel-framed wall panels taking into account displacement controlled behaviour for a diverse range of seismic conditions. Lateral load resisting elements in support of buildings made of cold-formed steel has been of major concern in seismic conditions given the apparent non-ductile behaviour of this type of material. It has been revealed in the research that this form of construction can possess significant strength and ductility reserves. Most bracing elements tend to be made up of a large number of components including structural frames, bracing elements and sheetings. Thus, modelling their potential response behaviour is not straightforward, and there are no standard test methods for determining their capacity in seismic conditions. The various test procedures used by an Australian manufacturer are mainly based on TR440 (Experimental Building Station, 1978) which considers principally the conditions of cyclonic wind. There are no provisions for determining bracing capacity of these walls for seismic performance in Australia. A comprehensive testing methodology has been developed in this research which is aimed at providing a practical and reliable means of evaluating the seismic resistant capacity of this increasingly common form of construction for the domestic housing market. Whilst numerous loading protocols exist for the pseudo-static cyclic testing of structures, the loading protocol developed in this research was derived from analyses of accelerograms that had been simulated specifically for design earthquake scenarios appropriate for regions of low-moderate seismicity, like Australia. Analyses undertaken were based mainly on magnitude-distance combinations and site conditions that would impose onerous drift demand on low-rise buildings. Experimental studies have been conducted on full scale isolated wall panels measuring 2.4 m x 2.4 m and 0.9 m x 2.4 m braced with fibre cement boards. A cyclic loading protocol that had been developed based on seismic conditions of Australia was used in the cyclic testing to ensure the validity and practicability of the testing. Important wall parameters such as elastic stiffness, yield displacement, ultimate displacement and structural ductility factor were evaluated from the test results using various existing methods together with the method proposed by the author of the thesis. Detailed analytical investigations of tested wall panels have been carried out by formulating three different analytical models namely; numerical model, hand calculation method and simplified hand calculation method, for…

In the present research, investigation was undertaken with regard to the behaviour of precast RC pinned beam-to-column connections, provided by steel dowels, under monotonic and cyclic loading. In accordance with the experimental data in hand, the effect of several parameters on the behaviour of the connection was examined, such as the concrete cover around the dowels, the number and diameter of the dowels, the strength of the grout filling, the imposition of severe deformations (rotations) at the joint etc. In the analytical part of this PhD thesis, a constitutive FE model was developed and calibrated with regard to the available experimental data, to be used for non linear analysis purposes. Τhe calibrated analytical model was further applied for the parametric investigation of the shear resistance of precast pinned connections. The contribution of the work reported herein refers to a proposed relationship for the calculation of the shear resistance of precast pinned beam-to-column connections subjected to monotonic and cyclic loading, under the effect of several parameters. Moreover, an approximate empirical force-displacement constitutive law is proposed for this type of connections, to be used for design and practical purposes.

Αντικείμενο της διατριβής υπήρξε η διερεύνηση της συμπεριφοράς προκατασκευασμένων αρθρωτών συνδέσεων δοκού-υποστυλώματος (υλοποιούμενων μέσω χαλύβδινων πείρων σύνδεσης) υπό μονοτονικές και ανακυκλιζόμενες δράσεις. Μέσω διατιθέμενων πειραματικών δοκιμών, καταγράφηκε η επιρροή διαφόρων παραμέτρων στην αντοχή και παραμορφωσιμότητα της σύνδεσης, όπως είναι η επικάλυψη των πείρων σύνδεσης με σκυρόδεμα, η διάμετρος και ο αριθμός των χρησιμοποιούμενων πείρων σύνδεσης, η αντοχή του κονιάματος στην περιοχή γύρω από τους πείρους, η επιβολή μεγάλων παραμορφώσεων (στροφών) στον κόμβο δοκού-υποστυλώματος κ.α. Εν συνεχεία βαθμονομήθηκε προσομοίωμα μη γραμμικής ανάλυσης με χρήση του λογισμικού ABAQUS και διεξήχθη αναλυτική παραμετρική διερεύνηση. Από την αξιολόγηση, σύγκριση και συνδυασμό των πειραματικών, θεωρητικών και αναλυτικών δεδομένων, προτάθηκε και βαθμονομήθηκε έκφραση υπολογισμού της αντοχής των εν λόγω συνδέσεων υπό τις διάφορες παραμέτρους που την επηρεάζουν και καταστρώθηκαν εμπειρικά διαγράμματα διατμητικής αντοχής-μετατόπισης υπό μονοτονική και ανακυκλιζόμενη φόρτιση, για πρακτικές εφαρμογές.
