Повний текст джерелаCette thèse introduit un nouveau type de motif appelé signature. La signature segmente une séquence d'itemsets, afin de maximiser la taille de l'ensemble d'items qui apparaît dans tous les segments. La signature a été initialement introduite pour identifier les produits favoris d'un consommateur de supermarché à partir de son historique d'achat. L'originalité de la signature vient du fait qu'elle identifie les items récurrents qui 1) peuvent apparaître à différentes échelles temporelles, 2) peuvent avoir des occurrences irrégulières et 3) peuvent être rapidement compris par des analystes. Étant donné que les approches existantes en fouille de motifs n'ont pas ces 3 propriétés, nous avons introduit la signature. En comparant la signature avec les méthodes de l'état de l'art, nous avons montré que la signature est capable d'identifier de nouvelles régularités dans les données, tout en identifiant les régularités détectées par les méthodes existantes. Bien qu'initialement liée au domaine de la fouille de motifs, nous avons également lié le problème de la fouille de signatures au domaine de la segmentation de séquences. Nous avons ensuite défini différents algorithmes, utilisant des méthodes liées à la fouille de motifs et à la segmentation de séquences. Les signatures ont été utilisées pour analyser un large jeu de données issu d'un supermarché français. Une analyse qualitative des signatures calculées sur ces consommateurs réels a montré que les signatures sont capables d'identifier les produits favoris d'un consommateur. Les signatures ont également été capables de détecter et de caractériser l'attrition de consommateurs. Cette thèse définit également 2 extensions de la signature. La première extension est appelée la sky-signature. La sky-signature permet de présenter les items récurrents d'une séquence à différentes échelles de temps. La sky-signature peut être vue comme une manière efficace de résumer les signatures calculées à toutes les échelles de temps possibles. Les sky-signatures ont été utilisées pour analyser les discours de campagne des candidats à la présidentielle américaine de 2016. Les sky-signatures ont identifié les principaux thèmes de campagne de chaque candidat, ainsi que leur rythme de campagne. Cette analyse a également montré que les signatures peuvent être utilisées sur d'autres types de jeux de données. Cette thèse introduit également une deuxième extension de la signature, qui permet de calculer la signature qui correspond le plus aux données. Cette extension utilise une technique de sélection de modèle basée sur le principe de longueur de description minimale, communément utilisée en fouille de motifs. Cette extension a également été utilisée pour analyser des consommateurs de supermarché

Повний текст джерелаRecommender systems have received a lot of attention over the past decades with the proposal of many models that take advantage of the most advanced models of Deep Learning and Machine Learning. With the automation of the collect of user actions such as purchasing of items, watching movies, clicking on hyperlinks, the data available for recommender systems is becoming more and more abundant. These data, called implicit feedback, keeps the sequential order of actions. It is in this context that sequence-aware recommender systems have emerged. Their goal is to combine user preference (long-term users' profiles) and sequential dynamics (short-term tendencies) in order to recommend next actions to a user. In this thesis, we investigate sequential recommendation that aims to predict the user's next item/action from implicit feedback. Our main contribution is REBUS, a new metric embedding model, where only items are projected to integrate and unify user preferences and sequential dynamics. To capture sequential dynamics, REBUS uses frequent sequences in order to provide personalized order Markov chains. We have carried out extensive experiments and demonstrate that our method outperforms state-of-the-art models, especially on sparse datasets. Moreover we share our experience on the implementation and the integration of REBUS in myCADservices, a collaborative platform of the French company Visiativ. We also propose methods to explain the recommendations provided by recommender systems in the research line of explainable AI that has received a lot of attention recently. Despite the ubiquity of recommender systems only few researchers have attempted to explain the recommendations according to user input. However, being able to explain a recommendation would help increase the confidence that a user can have in a recommendation system. Hence, we propose a method based on subgroup discovery that provides interpretable explanations of a recommendation for models that use implicit feedback

Odontocetes are assumed to use echolocation for navigation and foraging, but neither of these uses of biosonar has been conclusively demonstrated in free-ranging animals. Many bats are known to use echolocation throughout foraging sequences, changing the structure and timing of clicks as they progress towards prey capture. For odontocetes, however, we do not know enough about their foraging behavior to describe such sequences. To conduct detailed behavioral observations of any subject animal, the observer must be able to maintain continuous visual contact with the subject for a period commensurate with the duration of the behavior(s) of interest. Behavioral studies of cetaceans, which spend approximately 95% of their time below the water's surface, have been limited to sampling surface behavior except in special circumstances, e.g. clear-water environments, or with the use of technological tools. I addressed this limitation through development of an observation platform consisting of a remote controlled video camera suspended from a tethered airship with boat-based monitoring, adjustment, and recording of video. The system was used successfully to conduct continuous behavioral observations of bottlenose dolphins in the Sarasota Bay, FL area. This system allowed me to describe previously unreported foraging behaviors and elucidate functions for behaviors already defined but poorly understood. Dolphin foraging was modeled as a stage-structured sequence of behaviors, with the goal-directed feeding event occurring at the end of a series of search, encounter, and pursuit behaviors. The behaviors preceding a feeding event do not occur in a deterministic sequence, but are adaptive and plastic. A single-step transition analysis beginning with prey capture and receding in time has identified significant links between observed behaviors and demonstrated the stage-structured nature of dolphin foraging. Factors affecting the occurrence of specific behaviors and behavioral transitions include mesoscale habitat variation and individual preferences. The role of sound in foraging, especially echolocation, is less well understood than the behavioral component. Recent studies have explored the use of echolocation in captive odontocete foraging and presumed feeding in wild animals, but simultaneous, detailed behavioral and acoustic observations have eluded researchers. The current study used two methods to obtain acoustic data. The overhead video system includes two towed hydrophones used to record 'ambient' sounds of dolphin foraging. The recordings are of the 'ambient' sounds because the source of the sounds, i.e. animal, could not be localized. Many focal follows, however, were conducted with single animals, and from these records the timing of echolocation and other sounds relative to the foraging sequence could be examined. The 'ambient' recordings revealed that single animals are much more vocal than animals in groups, both overall and during foraging. When not foraging, single animals vocalized at a rate similar to the per animal rate in groups of>=2 animals. For single foraging animals, the use of different sound types varies significantly by the habitat in which the animal is foraging. These patterns of use coupled with the characteristics of the different sound types suggest specific functions for each. The presence of multiple animals in a foraging group apparently reduces the need to vocalize, and potential reasons for this pattern are discussed. In addition, the increased vocal activity of single foraging animals lends support to specific hypotheses of sound use in bottlenose dolphins and odontocetes in general. The second acoustic data collection method records sounds known to be from a specific animal. An acoustic recording tag was developed that records all sounds produced by an animal including every echolocation click. The tag also includes an acoustic sampling interval controller and a sensor suite that measures pitch, roll, heading, and surfacing events. While no foraging events occurred while an animal was wearing an acoustic data logger, the rates of echolocation and whistling during different activities, e.g. traveling, were measured.

Повний текст джерелаThis thesis belongs to the domain of decision theory under uncertainty and aims to understand, describe and represent individual choices in various decision contexts. Our work focuses on the fact that economic behavior is often influenced by the structure and the timing of resolution of uncertainty. In a first experimental part, we confronted subjects with different types of uncertainty, namely risk (known probabilities), uncertainty (unknown probabilities), compound risk and compound uncertainty, which were generated using special random devices. In chapter 1 we analyze the heterogeneity of attitudes towards ambiguity, compound risk and compound uncertainty whereas in chapter 2, we use rank dependent expected utility as a measuring tool in order to individually investigate these attitudes. Chapter 3 confronts the interpretation of ambiguity in term of second order beliefs with the experimental data and proposes a method for eliciting the function that encapsulates attitudes toward ambiguity in the “recursive” or multistage models of decision under uncertainty. The second part of the thesis deals with individual decision making under risk in a dynamic context and is composed of two independent experimental studies. Both of them rely on the decomposition of the independence axiom into three dynamic axioms: consequentialism, dynamic consistency and reduction of compound lotteries. Chapter 4 reports experimental data about violations of each of the three axioms. Chapter 5 presents a conceptual categorization of individual behavior in sequential decision problems under risk, especially those which do not conform to the independence axiom. We propose an experiment specially designed to test the predictions of this categorization

Повний текст джерелаThe aim of my PhD thesis was to participate in the construction of a new humanoid robot that can sustain intuitive interactions with humans through observation and imitation. As such, I conducted a series of experimental studies in young adults to better characterize the kinematic properties of those arm movements performed during motor and social interactions, elements that are the reference patterns for the to-come robot. Focusing on non-verbal behavior, we tested how external and internal constraints (difficulty, predictability, timing) shaped the kinematics of both arm and hand movements in a very simple pick and place sequential action (study 1 and 2). The results revealed early modulations in kinematics in the reach-to-grasp phase depending of the size and the stability of the target pad on which the object had to be placed. These modulations observed within the first element of the sequence were in contradiction with the current optimized trajectory models used in robotics for action sequences. They suggest in fact a strong coupling of the motor parameters within an encapsulated planning strategy that back-propagates the contextual constraints on to the early elements of the motor sequence. To confirm these findings, a second serie of studies were conducted using kinematic and video based tasks to show that human motor intentions can be read through the detection of these early kinematic modulations (study 3). Using basic artificial classification, we tested whether low-revel motor indices could afford trial categorization without the need for higher-level process such as motor imagery. results indicated that indeed without cognitive abilities the neural network could categorize the intention of an observed action within the first 500ms, significantly above chance level (study 4). The third place of my PhD work turned to eye tracking. Here, we revealed that the proactive strategy of eye-fixations used during action observation were similar to those made during executed actions. Additionally, good categorization of motor intention was characterized by more accurate saccades and longer object fixations. Eye movements are known to play an important role in social intercations. Hence, in a final experiment (study 5), we setup a face-to-face competitive game to reveal the specific effects thet the social context may play on the kinematic properties of reaching during different types of interactive situations. In the PhD mansucript, I propose a general discussion that sets these results within the current cognitive and neuronal models of sensori-motor integration. When appropriate, future directions are suggested both for cognitive models of motor control and for the development of neuro-inspired articicial systems constitued with intuitive social interaction skills

Повний текст джерелаApproximately 20% of youth in the U.S. are experiencing a mental health challenge; a rate that is said to increase by more than 50% by 2020. Schools are the largest provider of mental health services to youth, yet two of schools’ most efficacious evidence-based systems, Positive Behavioral Interventions and Supports (PBIS) and school mental health (SMH), often exist in isolation. Interconnected Systems Framework (ISF) unites these two systems to improve school and life outcomes for all students, but especially, students who struggle with or are at risk of developing mental health challenges. The current study measured New York City metropolitan area principals’ initial readiness to implement ISF. This researcher found that principals in schools that implemented PBIS indicated significantly greater levels of initial readiness to implement ISF than principals in schools that did not implement PBIS. Sequential multiple regression models showed the variance of independent variables, elements of ISF, that predicted initial readiness to implement ISF. The elements “teaching appropriate behaviors to all students” and “acknowledging all students for behavioral achievement, school-wide”, serve as strong recommendations for principals in the exploration and adoption stage of ISF. As policy makers prepare for the new presidency and the inception of the Every Student Succeeds Act (ESSA), they should reflect on the goals, strengths, and needs of their students and equip students, families, schools, and communities so they can be achieved. Although most of data analysis yields to no significance, that in and of itself is significant. Student need and implementation challenges are consistent across the region.

Повний текст джерелаEsta tesis consta de tres ensayos sobre las expectativas de inflación, la incertidumbre de la predicción, y la importancia de la incertidumbre en subastas secuenciales. Todos ellos utilizan un método experimental. El capítulo 1 estudia cómo los individuos predicen la inflación en la economía ficticia y analiza el efecto de las reglas de política monetaria en sus decisiones. Los resultados revelan la heterogeneidad en las reglas de predicción de la inflación y demuestran la importancia del mecanismo de aprendizaje adaptivo si el cambio entre los modelos se supone. Capítulo 2 continúa el análisis del capítulo 1, analiza la incertidumbre individual de las expectativas de inflación. Los resultados muestran que los intervalos de confianza dependen de varianza de la inflación y la fase del ciclo económico, tienen una fuerte inercia, y son frecuentemente asimétricos. Por último, el capítulo 3 analiza la influencia de la incertidumbre sobre el número de oferentes en el comportamiento de los individuos en un experimento de la subasta secuencial. La incertidumbre no agrava la caída de los precios, pero cambia las estrategias de los oferentes y la eficiencia de la subasta.

Повний текст джерелаIn the first essay, we present a general out-of-equilibrium framework for strategic thinking in sequential games. It assumes the agents to take decisions on restricted game trees, according to their (limited) foresight level, following backward induction. Therefore we talk of limited backward induction (LBI). We test for LBI using a variant of the race game. Our design allows to identify restricted game trees and backward reasoning, thus properly disentangling LBI behavior. The results provide strong support in favor of LBI. Most players solve intermediate tasks - i.e. restricted games - without reasoning on the terminal histories. Only a small fraction of subjects play close to equilibrium, and (slow) convergence toward it appears, though only in the base game. An intermediate task keeps the subjects off the equilibrium path longer than in the base game. The results cannot be rationalized using the most popular models of strategic reasoning, let alone equilibrium analysis.
In the second essay, a subtle implication of the model is investigated: the sensitivity of the players’ foresight to the accessibility and completeness of the information they have, using a Centipede game. By manipulating the way in which information is provided to subjects, we show that reduced availability of information is sufficient to shift the distribution of take-nodes further from the equilibrium prediction. On the other hand, similar results are obtained in a treatment where reduced availability of information is combined with an attempt to elicit preferences for reciprocity, through the presentation of the centipede as a repeated trust game. Our results could be interpreted as cognitive limitations being more effective than preferences in determining (shifts in) behavior in our experimental centipede. Furthermore our results are at odds with the recent ones in Cox [2012], suggesting caution in generalizing their results. Reducing the availability of information may hamper backward induction or induce myopic behavior, depending on the strategic environment.
The third essay consists of an experimental investigation of farsighted versus myopic behavior in network formation. Pairwise stability Jackson and Wolinsky [1996] is the standard stability concept in network formation. It assumes myopic behavior of the agents in the sense that they do not forecast how others might react to their actions. Assuming that agents are perfectly farsighted, related stability concepts have been proposed. We design a simple network formation experiment to test these extreme theories, but find evidence against both of them: the subjects are consistent with an intermediate rule of behavior, which we interpret as a form of limited farsightedness. On aggregate, the selection among multiple pairwise stable networks (and the performance of farsighted stability) crucially depends on the level of farsightedness needed to sustain them, and not on efficiency or cooperative considerations. Individual behavior analysis corroborates this interpretation, and suggests, in general, a low level of farsightedness (around two steps) on the part of the agents.

Повний текст джерелаBehavioural studies suggest that complex behaviours are multiscale processes, which may be composed of elementary ones (units or primitives). Traditional approaches to cognitive mod-elling generally employ reductionistic (mostly static) representations and computations of simplistic dynamics. The thesis proposes functional architectures to capture the dynamical structure of both functional units and the composite multiscale behaviours. First, a mathe-matical formalism of functional units as low dimensional, structured flows in phase space is introduced (functional modes). Second, additional dynamics (operational signals), which act upon functional modes for complex behaviours to emerge, are classified according to the separation between their characteristic time scale and the one of modes. Then, complexity measures are applied to distinct architectures for a simple composite movement and reveal a trade off between the complexities of functional modes and operational signals, depending on their time scale separation (in support of the control effectiveness of architectures employing non trivial modes). Subsequently, an architecture for serial behaviour (along the example of handwriting) is demonstrated, comprising of functional modes implementing characters, and operational signals much slower (establishing a mode competition and ‘binding’ modes into sequences) or much faster (as meaningful perturbations). All components being coupled, the importance of time scale interactions for behavioural organization is illustrated. Finally, the contributions of modes and signals to the output are recovered, appearing to be possible only through analysis of the output phase flow (i.e., not from trajectories in phase space or time)

Повний текст джерелаThis dissertation presents a trajectory analysis framework, which includes both a preprocessing phase and trajectory mining process. Furthermore, the framework offers visual functions that reflect trajectory patterns evolution behavior. The originality of the mining process is to leverage frequent emergent pattern mining and formal concept analysis for moving objects trajectories. These methods detect and characterize pattern evolution behaviors bound to time in trajectory data. Three contributions are proposed: (1) a method for analyzing trajectories based on frequent formal concepts is used to detect different trajectory patterns evolution over time. These behaviors are "latent", "emerging", "decreasing", "lost" and "jumping". They characterize the dynamics of mobility related to urban spaces and time. The detected behaviors are automatically visualized on generated maps with different spatio-temporal levels to refine the analysis of mobility in a given area of the city, (2) a second trajectory analysis framework that is based on sequential concept lattice extraction is also proposed to exploit the movement direction in the evolution detection process, and (3) prediction method based on Markov chain is presented to predict the evolution behavior in the future period for a region. These three methods are evaluated on two real-world datasets. The obtained experimental results from these data show the relevance of the proposal and the utility of the generated maps

This practice has raised concerns on the prospect of inorganic metals release to the surface and groundwater in the vicinity of the ash dump. Acceptable scientific studies are lacking to determine the best ash disposal practices. Moreover, knowledge about the mobility patterns of inorganic species as a function of mineralogical association or pH susceptibility of the dry disposed ash dump under natural weathering conditions are scarce in the literature. Fundamental understanding of chemical interactions of dry disposed ash with ingressed CO2 from atmosphere, percolating rain water and brine irrigation within ash disposal sites were seen as key areas requiring investigation. The mineralogical association of inorganic species in the dry disposed ash cores can be identified and quantified. This would provide a basis for understanding of chemical weathering, mineralogical transformations or mobility patterns of these inorganic species in the dry ash disposal scenario. The current study therefore aims to provide a comprehensive characterisation of weathered dry disposed ash cores, to reveal mobility patterns of chemical species as a function of depth and age of ash, with a view to assessing the potential environmental impacts. Fifty-nine samples were taken from 3 drilled cores obtained respectively from the 1 year, 8 year and 20-year-old sections of sequentially dumped, 
weathered, dry disposed ash in an ash dump site at Tutuka - a South African coal burning power station. The core samples were characterized using standard analytical procedures viz: X-ray fluorescence (XRF), X-ray diffraction (XRD), Fourier transforms infrared (FTIR) techniques, Scanning electron microscopy/energy dispersive spectroscopy (SEM/EDS) and Acid neutralisation capacity (ANC) test. A modified sequential extraction (SE) method was used in this study. The chemical partitioning, mobility and weathering patterns in 1 year, 8 year and 20-year-old sections of the ash dump were respectively investigated using this modified sequential extraction scheme. The sequence of the extractions was as follows: (1) water soluble, (2) exchangeable, (3) carbonate, (4) iron and manganese and (5) residual. The results obtained from the 5 steps sequential extraction scheme were validated with the total metal content of the original sample using mass balance method. The distribution of major and trace elements in the different liquid fractions obtained after each step of sequential extraction of the 59 drilled core samples was determined by inductively coupled plasma mass spectrometry (ICPMS). The data generated for various ash core samples were explored for the systematic analysis of mineralogical transformation and change in ash chemistry with ageing of the ash. Furthermore, the data was analyzed to reveal the impact of ingressed CO2 from atmosphere, infiltrating rain water and brine irrigation on the chemistry of ash core samples. Major mineral phases in original ash core samples prior to extraction are quartz (SiO2) and mullite (3Al2O3·
2SiO2). Other minor mineral phases identified were hematite (Fe2O3), calcite (CaCO3), lime (CaO), anorthite (CaAl2Si2O8), mica (Ca (Mg, Al)3 (Al3Si) O10 (OH)2), and enstatite (Mg2Si2O6). X-ray diffraction results show significant loss of crystallinity in the older ash cores. The presence of minor phases of calcite and mica in dry disposed ash cores are attributed to reduction in the pore water pH due to hydration, carbonation and pozzolanic reactions. The X-ray diffraction technique was unable to detect Fe-oxyhydroxide phase and morealuminosilicate phases in ash core samples due to their low abundance and amorphous character. X-ray fluorescence results of the original ash core samples showed the presence of major oxides, such as SiO2, Al2O3, Fe2O3, while CaO, K2O, TiO2, Na2O, MnO, MgO, P2O5, and SO3 occur in minor concentrations. The ratio of SiO2/Al2O3 classified the original core samples prior to extraction as a silico-aluminate class F fly ash. The ternary plot of major elements in 1-year-old ash core samples was both sialic and ferrocalsialic but 8 year and 20-year-old ash core samples were sialic in chemical composition. It is noteworthy that the mass % of SiO2 varies through the depth of the core with an increase of nearly 3 %, to 58 mass % of SiO2 at a depth of 6 m in the 1-year-old core whereas in the case of the 8-year-old core a 2 % increase of SiO2 to a level of 57.5 mass % can be observed at levels between 4-8 m, showing dissolution of major components in the matrix of older ash cores.. The Na2O content of the Tutuka ash cores was low and varied between 0.6-1.1 mass % for 1-year-old ash cores to around 0.6-0.8 mass % for 8-year-old ash cores. Sodium levels were higher in 1-year-old ash cores compared to 8 year and 20-year-old ashcores. Observed trends indicate that quick weathering of the ash (within a year) leached out Na+ from the ash dump. No evidence of Na+ encapsulation even though the ash dump was brine irrigated. Thus the dry disposal ash placement method does not result in a sustainable salt sink for Na-containing species over time. The total content of each of the elements in 1 year and 20-year-old ash cores was normalised with their total content in fresh ash from same power station to show enrichment and depletion factor. Major elements such as K+, Mn showed enrichment in 1-year-old ash cores whereas Al, Si, Na+, Ti, Ca, Mg, S and Fe showed depletion due to over time erosion. Trace elements such as Cr, Sr, P, Ba, Pb, V and Zn showed enrichment but Ni, Y, Zr showed depletion attributed to over time erosion. In 20-year-old ash cores, major elements such as Al, Na+ and Mn showed enrichment while Si, K+, Fe, Mg and Ca showed depletion highlighting their mobility. Trends indicated intensive flushing of major soluble components such as buffering constituents (CaO) by percolating rain water. The 1-year-old and 20-year-old coal ash cores showed a lower pH and greater loss/depletion of the soluble buffering constituents than the 2-week-old placed ash, indicating significant chemical weathering within a year. Based 
on ANC results the leaching behaviours of Ca, Mg, Na+, K+, Se, Cr, and Sr were found to be controlled by the pH of the leachant indicating high mobility of major soluble species in the ash cores when in contact with slightly acid rain water. Other investigated toxic metals such as As, Mo and Pb showed amphoteric behaviour with respect to the pH of the leachant. Chemical alterations and formation of transient minor secondary mineral phases was found to have a significant effect on the acid susceptibility and depletion pattern of chemical species in the core ash samples when compared to fresh ash. These ANC results correlated well with the data generated from the sequential extraction scheme. Based on sequential extraction results elements, showed noticeable mobility in the water soluble, exchangeable and carbonate fractions due to adsorption and desorption caused by variations in the pore water pH. In contrast, slight mobility of elements in the Fe and Mn, and residual fractions of dry disposed fly ashes are attributed to the co-precipitation and dissolution of minor amount of less soluble secondary phase overtime. The 1-year-old dry disposed ash cores were the least weathered among the 3 drilled ash cores. Therefore low concentration of toxic metals in older ash cores were ascribed to extensive weathering with slower release from residual mineral phases over time. Elements were found to associate with different mineral phases depending on the age or depth of the core samples showing greater heterogeneity in dispersion. For instance the average amount of total calcium in different mineral associations of 1-year-old ash cores is as follows
water soluble (10.2 %), exchangeable (37.04 %), carbonate (37.9 %), Fe and Mn (7.1 %) and residual (2.97 %). The amount of total Na+ in different mineral phases of 1-year-old ash cores followed this trend: water soluble (21 %), exchangeable (11.26 %), carbonate (2.6 %), Fe and Mn (4.7 %) and residual (53.9 %). The non-leachable portion of the total Na+ content (namely that contained in the residual fraction) in the 1-year-old ash core samples under conditions found in nature ranged between 5-91 %. This non-leachable portion of the Na+ showed the metastability of the mineral phases with which residual Na+ associates. Results showed older ash cores are enriched in toxic elements. Toxic elements such as As, B, Cr, Mo and Pb are enriched in the residual fraction of older ash cores. For instance As concentration in the residual fraction varied between 0.0003- 0.00043 mg kg-1 for 1-year-old ash cores to around 0.0003-0.0015 mg kg-1 for 20-year-old ash cores. This suggests that the older ash is enriched in toxic elements hence dust from the ash dump would be toxic to human health. The knowledge of mobility and ecotoxicological significance of coal fly ash is needed when considering its disposal or reuse in the environment. The mobility and ecotoxicology of inorganic metals in coal fly ash are determined by (i) mineralogical associations of inorganic species (ii) in-homogeneity in the ash dumps (iii) long and short term exposure to ingress CO2 and percolating rain water. Management issues such as inconsistent placement of ash in the dumps, poor choice of ash dump site, in-homogeneity in brine irrigation, no record of salt load put on the ash dumps and lack of proper monitoring requires improvement. The thesis provides justification for the use of the modified sequential extraction scheme as a predictive tool and could be employed in a similar research work. This thesis also proved that the dry ash disposal method was not environmental friendly in terms of overall leaching potential after significant chemical weathering. Moreover the study proved that the practice of brine co-disposal or irrigation on ash dumps is not sustainable as the ash dump did not act as a salt sink.

We start by introducing an alternative characterization for martingale measures in discrete time financial markets models, relating the existence of such measures with a special family of optimization problems. We then move on to address two classical problems in mathematical finance, both connected through the incompleteness of the markets under consideration. We first consider a minimization problem as a model for the interaction between two agents trading a contingent claim in incomplete financial markets (in both discrete-time and continuous-time setups). The agents personal valuations for the contingent claim are assumed to depend on probability measures representing their beliefs concerning the future states of the world, and their goal is to achieve a common price for the contingent claim to be traded, while deviating as little as possible from their initial beliefs. We then prove a dynamic programming principle for a finite horizon optimal control problem for which the state variable dynamics are defined by a Markov- switching jump-diffusion stochastic differential equation. As an application of our results, we study a finite horizon consumption-investment problem in a Markov-switching jump-diffusion financial market.
Nesta Tese de Doutoramento usamos conceitos de Sistemas Dinâmicos, Cálculo Variacional e técnicas de Controlo para lidar com três problemas em Matemática Financeira. Começamos por uma caracterização alternativa das medidas martingale em modelos de mercados financeiros em tempo discreto, relacionando a existência de tal medida com uma família de problemas de optimização. Posteriormente, estudamos dois problemas clássicos em matemática financeira, relacionados pela incompletude dos mercados considerados. O primeiro é um problema de minimização que modela a interação entre dois agentes, que transacionam um derivado financeiro em mercados financeiros incompletos (quer em tempo discreto, quer em tempo contínuo). Assumimos que a avaliação que cada agente faz do derivado financeiro depende de medidas de probabilidade que representam as suas estimativas sobre a probabilidade de ocorrência de cada um dos futuros estados do mundo, e que o seu objetivo consiste em conseguir um preço comum para o derivado financeiro negociado, desviando-se o mínimo possível das suas estimativas iniciais. Finalmente, provamos um princípio de programação dinâmica para um problema de controlo óptimo em horizonte finito, no qual a dinâmica das variáveis de estado é definida por uma equação diferencial estocástica contendo termos de difusão, termos de saltos, sendo, adicionalmente, cada um destes termos modulado por uma cadeia de Markov. Como aplicação estudamos um problema de consumo-investimento em horizonte finito num mercado financeiro formado por activos cuja evolução com o tempo segue uma equação diferencial estocástica do tipo acima descrito.

Повний текст джерелаFace to face interaction is one of the most fundamental forms of human communication. It is a complex multimodal and coupled dynamic system involving not only speech but of numerous segments of the body among which gaze, the orientation of the head, the chest and the body, the facial and brachiomanual movements, etc. The understanding and the modeling of this type of communication is a crucial stage for designing interactive agents capable of committing (hiring) credible conversations with human partners. Concretely, a model of multimodal behavior for interactive social agents faces with the complex task of generating gestural scores given an analysis of the scene and an incremental estimation of the joint objectives aimed during the conversation. The objective of this thesis is to develop models of multimodal behavior that allow artificial agents to engage into a relevant co-verbal communication with a human partner. While the immense majority of the works in the field of human-agent interaction (HAI) is scripted using ruled-based models, our approach relies on the training of statistical models from tracks collected during exemplary interactions, demonstrated by human trainers. In this context, we introduce "sensorimotor" models of behavior, which perform at the same time the recognition of joint cognitive states and the generation of the social signals in an incremental way. In particular, the proposed models of behavior have to estimate the current unit of interaction ( IU) in which the interlocutors are jointly committed and to predict the co-verbal behavior of its human trainer given the behavior of the interlocutor(s). The proposed models are all graphical models, i.e. Hidden Markov Models (HMM) and Dynamic Bayesian Networks (DBN). The models were trained and evaluated - in particular compared with classic classifiers - using datasets collected during two different interactions. Both interactions were carefully designed so as to collect, in a minimum amount of time, a sufficient number of exemplars of mutual attention and multimodal deixis of objects and places. Our contributions are completed by original methods for the interpretation and comparative evaluation of the properties of the proposed models. By comparing the output of the models with the original scores, we show that the HMM, thanks to its properties of sequential modeling, outperforms the simple classifiers in term of performances. The semi-Markovian models (HSMM) further improves the estimation of sensorimotor states thanks to duration modeling. Finally, thanks to a rich structure of dependency between variables learnt from the data, the DBN has the most convincing performances and demonstrates both the best performance and the most faithful multimodal coordination to the original multimodal events

With the development and popularization of technology, human interaction has gradually changed from physical to virtual interaction. This purpose of the study is, through the online game "League of Legends," to understand the causes of network conflicts between players. Currently very few studies analyze the online game conflict behaviors. The purpose of this research is to investigate online game conflict behaviors by applying Bakeman (1986) sequential analysis. The study found that in the conflict behavior of online players, the transition of conflict behavior between players is gradual. When a low degree of conflict occurs, bad communication approaches turned conflicts into high-level conflicts. After comparing online game conflicts with traditional interpersonal conflicts, there is no difference between the two. Because of the characteristics of the network, people are less restricted to social norms in the online world. The research shows the behavior that may not be presented in the interaction between people and people, which leads to more serious conflicts
