Resumo:

Aiming at some uncertainty problems such as quality inspection of adhesive structure and risk assessment in the practical engineering application, a possibility estimation model is established. Firstly, according to the fuzziness, randomness and uncertainty of the measurement data, a transformation method of possibility distribution with non-single peak values and nonlinearity is proposed from probability density function. Secondly, for possibility distributions of measurement data of each sensor, a kind of possibility fusion rules is put forward, then the fusion distribution is estimated by the possibility mean. Finally the model is applied to the mechanical property estimation of adhesive structure, and the result forecasts the quality. The proposed model with strong applicability, not only provides convenience for the operations among possibility distributions, but also offers new ideas and new methods to deal with uncertain problems.

Resumo:

The multiple statistical hypotheses two-stage testing with possibility of rejecting of decision to make choice between hypotheses concerning the pair of groups of probability distributions is considered such that in the first stage one group of distributions is distinguished and then in the second stage, the true distribution is denoted between mentioned group of probability distributions. Description of characteristics of logarithmically asymptotically optimal (LAO) hypotheses testing with possibility of decision rejection and the matrix of optimal asymptotically interdependencies of all pairs of the error probability exponents or reliabilities are studied. The goal of research is to express the optimal functional relation between the reliabilities of LAO hypotheses testing by a pair of stages and to compare with the case of similar one-stage testing.

A new approach to normalizing fuzzy sets is introduced where it is assumed that the normalization method is compatible with a given t-norm. In this context it is proved that the most usual ways to normalize fuzzy subsets correspond to the most common t-norms. For a given fuzzy subset μ, the corresponding normalized fuzzy subset [Formula: see text] can be viewed as the distribution of μ conditioned on the (degree of) existence of its elements with maximal membership. From this view point we investigate the less specific normal fuzzy subset of X among the most similar fuzzy subsets to μ and the normal fuzzy subset generating the same fuzzy T-preorder as μ.

Dans cette thèse, nous proposons une nouvelle méthode d'estimation non-paramétrique de la densité de probabilité. Cette méthode d'estimation imprécise combine la théorie de distribution de Schwartz et la théorie de possibilité. La méthode d'estimation que nous proposons est une extension de la méthode d'estimation à noyau. Cette extension est basée sur une nouvelle méthode de représentation de la notion de voisinage sur laquelle s'appuie l'estimation à noyau. Cette représentation porte le nom de noyau maxitif. L'estimation produite est de nature intervalliste. Elle est une enveloppe convexe d'un ensemble d'estimation de Parzen-Rosenblatt obtenus avec un ensemble de noyaux contenus dans une famille particulière. Nous étudions un certain nombre des propriétés théoriques liées à cette nouvelle méthode d'estimation. Parmi ces propriétés, nous montrons un certain type de convergence de cet estimateur. Nous montrons aussi une aptitude particulière de ce type d'estimation à quantifier l'erreur d'estimation liée à l'aspect aléatoire de la distribution des observations. Nous proposons un certain nombre d'algorithmes de faible complexité permettant de programmer facilement les mathodes que nous proposons.

Actuellement, les Modèles Numériques de Surface (MNS) sont nécessaires pour de nombreuses applications, telles que la gestion des ressources en eau, le suivi de la biomasse, l’évaluation des dommages causés par les catastrophes naturelles ou la planification urbaine. Les MNS peuvent principalement être produits par interférométrie Radar, photogrammétrie ou en utilisant des instruments LiDAR. Dans ce contexte, le CNES et Airbus préparent le lancement de la constellation de satellites CO3D afin d’assurer la production massive de MNS à haute résolution par photogrammétrie. Fournie avec le MNS, une carte de performance permettra de caractériser les erreurs liées aux incertitudes dans les données d’entrée ainsi qu’aux incertitudes des méthodes utilisées. L’objectif de cette thèse et de caractériser l’incertitude associée à la production de MNS par photogrammétrie. Nous utilisons des modèles d’incertitude spécifiques, à savoir des probabilités imprécises, et plus particulièrement des distributions de possibilité, afin de caractériser l’incertitude résultant du traitement des images stéréo. Ces modèles définissent des “ensembles crédaux”, qui sont des ensembles convexes de distributions de probabilité. L’intérêt de ces ensembles crédaux est d’être mieux adaptés pour représenter l’incertitude résultant de connaissances incomplètes ou imparfaites, par rapport aux simples distributions de probabilité. En présence de plusieurs sources d’incertitudes, il est également nécessaire de considérer leurs relations de dépendance. Pour cela, il est courant d’utiliser des copules, qui sont des modèles représentant la dépendance entre plusieurs variables aléatoires. Dans cette thèse, trois méthodes distinctes sont introduites afin de joindre des ensembles crédaux marginaux en des ensembles crédaux multivariés à l’aide de copules. Les relations entre ces méthodes sont ensuite étudiées pour des copules spécifiques ainsi que pour différents modèles de probabilités imprécises. Une application de ces ensembles crédaux multivariés est ensuite proposée, afin de propager l’incertitude d’images stéréo dans un problème d’appariement. Différentes optimisations et façons de faciliter la propagation de l’incertitude sont présentées. La propagation correcte de l’incertitude est enfin validée à l’aide de méthodes de Monte-Carlo. Une seconde contribution de cette thèse concerne la modélisation de l’incertitude intrinsèque de l’algorithme d’appariement en utilisant des distributions de possibilité. Une méthode est proposée pour générer des intervalles de confiance associés aux résultats de l’étape d’appariement, et ces intervalles sont propagés jusqu’à la fin du pipeline stéréo, produisant ainsi des intervalles de confiance d’élévation pour les MNS. La taille et la précision de ces intervalles est évaluée en utilisant des images satellites réelles et des MNS pour lesquels une vérité terrain est disponible. Les intervalles ainsi créés contiennent correctement la vérité terrain au moins 90 % du temps
Currently, Digital Surface Models (DSMs) are required in many applications, such as for managing water resources, monitoring biomass, evaluating damages caused by natural catastrophes, or for urban planning. DSMs can mainly be produced by Radar interferometry, photogrammetry or LiDAR scanning. In this context, CNES and Airbus are planning the launch of the CO3D constellation of satellites to massively provide highly accurate DSMs using photogrammetry. A performance map will also be provided alongside the DSM to characterize potential errors resulting from the uncertainty on input data or on its processing. The objective of this thesis is to characterize the uncertainty associated with the production of DSMs using photogrammetry. To do so, special uncertainty models, namelyimprecise probabilities, and more specifically possibility distributions, are employed to characterize the uncertainty arising from stereo images processing. Those models define credal sets, which are convex sets of probability distributions. Credal sets are well-suited to represent uncertainty resulting from incomplete or imperfect knowledge, which can be a limitation for a single probability distribution. In the presence of multiple sources of uncertainty, their dependency must also be considered. For this purpose, it is possible to consider copulas, which are models used to represent the dependency between multiple random variables. In this thesis, three different methods are introduced to join marginal credal sets into multivariate credal sets using copulas. The relationships between those methods are then investigated, for specific copulas and different models of imprecise probabilities. An application of those multivariate credal sets is then proposed, for propagating the uncertainty of stereo images in a dense stereo-matching problem. Different optimizations and ways to facilitate the uncertainty propagation are presented. The correct uncertainty propagation is validated using Monte Carlo sampling. A second contribution of this thesis concerns the uncertainty modeling of the dense matching algorithm itself using possibility distributions. A method is presented for generating confidence intervals associated with the results of the dense-matching step. Those intervals are then propagated to the end of the stereo pipeline, therefore producing elevation confidence intervals for the DSMs. The size and accuracy of intervals are then evaluated, using real satellites images and DSMs for which a ground truth is available. Elevation intervals correctly contain the ground truth at least 90% of the time

Les travaux présentés dans cette thèse concernent le thème des fonctionnalités visuelles qu'il convient d'embarquer sur un robot mobile, afin qu'il puisse se déplacer dans son environnement. Plus précisément, ils ont trait aux méthodes de perception par vision stéréoscopique dense, de modélisation de l'environnement par grille d'occupation, et de suivi visuel d'objets, pour la navigation autonome d'un robot mobile dans un environnement d'intérieur. Il nous semble important que les méthodes de perception visuelle soient à la fois robustes et rapide. Alors que dans les travaux réalisés, on trouve les méthodes globales de mise en correspondance qui sont connues pour leur robustesse mais moins pour être employées dans les applications temps réel et les méthodes locales qui sont les plus adaptées au temps réel tout en manquant de précision. Pour cela, ce travail essaye de trouver un compromis entre robustesse et temps réel en présentant une méthode semi-locale, qui repose sur la définition des distributions de possibilités basées sur une formalisation floue des contraintes stéréoscopiques.Il nous semble aussi important qu'un robot puisse modéliser au mieux son environnement. Une modélisation fidèle à la réalité doit prendre en compte l'imprécision et l'incertitude. Ce travail présente une modélisation de l'environnement par grille d'occupation qui repose sur l'imprécision du capteur stéréoscopique. La mise à jour du modèle est basée aussi sur la définition de valeurs de crédibilité pour les mesures prises.Enfin, la perception et la modélisation de l'environnement ne sont pas des buts en soi mais des outils pour le robot pour assurer des tâches de haut niveau. Ce travail traite du suivi visuel d'un objet mobile comme tâche de haut niveau
This work concerns visual functionalities to be embedded in a mobile robot for navigation purposes. More specifically, it relates to methods of dense stereoscopic vision based perception, grid occupancy based environment modeling and object tracking for autonomous navigation of mobile robots in indoor environments.We consider that is important for visual perception methods to be robust and fast. While in previous works, there are global stereo matching methods which are known for their robustness, but less likely to be employed in real-time applications. There are also local methods which are more suitable for real time but imprecise. To this aim, this work tries to find a compromise between robustness and real-time by proposing a semi-local method based on the definition of possibility distributions built around a fuzzy formalization of stereoscopic constraints.We consider also important for a mobile robot to better model its environment. To better fit a model to the reality we have to take uncertainty and inaccuracy into account. This work presents an occupancy grid environment modeling based on stereoscopic sensor inaccuracy.. Model updating relies on the definition of credibility values for the measures taken.Finally, perception and environment modeling are not goals but tools to provide robot high-level tasks. This work deals with visual tracking of a moving object such as high-level task

Une représentation connaissances centrées objets, déclarative et uniforme, est présentée. Elle permet de construire une base d'objets dynamique. Le mécanisme d'exploitation associé est fondé sur un processus élémentaire de filtrage flou. De façon générale, il permet l'exploitation d'une base d'objets dans laquelle les traitements sont aussi spécifiés de façon déclarative. Il permet aussi la manipulation de termes du langage naturel définis à l'aide d'outils mathématiques extraits de la théorie des ensembles flous. Le processus manipule la sémantique des objets à l'aide d'informations typées. Il calcule des distances entre objets variant entre 0 et 1 au lieu de rendre de simples réponses binaires. Deux stratégies de filtrage permettent des raisonnements nuancés et de diverses natures. Ces outils sont manipulés pour élaborer un système intelligent d'aide à la modélisation mathématique en biologie

Since there is a significant potential to supervise the low voltage network with the assistance of the end-customer smart meters, Vattenfall Eldistribution AB wants to take advantage of such data. Therefore, this project’s overall goal is to investigate how some specific grid disturbances could be detected in certain meter data types. There is a plethora of event data from several different grid areas with their own unique set of customers and power flow. Furthermore, the project aims to propose a detection method within the smart meter’s capability and explore the possibility of using smart meter data to identify the grid’s state. The literature study suggested that the machine learning approaches k-means and SVM were suggested to be used within this study’s scope. Several supervised and unsupervised machine learning algorithms have been identified and applied to power quality issues in various ways. Furthermore, each approach had four cases applied as well to broaden the analysis. After conducting the study, the project results show that smart meter data indeed has the potential to be used in machine learning methods to identify weak grids. However, the study shows that the information gained from smart meter data in its current state alone is not enough to distinguish weak grids from strong grids. For instance, the current data could complement grid data, such as loop impedance and topology data. Future work could include using the same machine learning methods on higher dimensions input data to separate the data points. One way to diversify the data could be to include data describing grid topology and data from PQ-meters. Furthermore, it will be possible to continuously monitor the low voltage grid conditions with future smart meters. In turn, this may give a better insight into how the voltage levels behave for weak and strong grids, respectively.
Vattenfall Eldistribution AB har en stor andel smarta mätare som registrerar elkvalitetsproblem på lågspänningsnätet. Detta medför att det finns stor potential att övervaka lågspänningsnätet med hjälp av data från dessa mätare. Därför är det övergripande målet med detta projekt att undersöka hur vissa specifika nätstörningar uppstår i vissa typer av mätdata. Det finns dessutom en uppsjö av data från många olika nätområden där alla har sin egna unika uppsättning av kunder och energi- flöden. Vidare syftar projektet till att utveckla en detekteringsmetod inom smartmätarens kapacitet och utforska möjligheten att använda smarta mätdata för att identifiera nätets tillstånd. Från litteraturstudien drogs slutsatsen att k-means och SVM var de mest lämpade metoderna att användas för denna studie. Flera maskininlärningsmetoder har identifierats och tillämpats på elkvalitetsproblem. Vidare analyserades data för fyra olika fall per metod. Efter att ha genomfört studien visade resultatet att data från smarta mätare sannerligen har potential att analyseras med maskininlärningsmetoder för att identifiera svaga nät. Däremot indikerar studien att den information som kan utvinnas från smarta mätare i det nuvarande läget inte är tillräckligt för att urskilja svaga nät från starka nät. Exempelvis kan data från smarta mätare kompletteras med nätdata, såsom impedans, och information om nätets topologi. Framtida projekt skulle därför kunna applicera samma maskininlärningsmetoder på indata med högre dimensioner för att möjliggöra en separation av data på flera plan. Ett sätt att diversifiera data vore att inkludera exempelvis information som beskriver nättopologi och data från PQ-mätare. Vidare kommer framtida mätare ha möjlighet att övervaka nätets spänning och ström kontinuerligt.

Community-based tourism (CBT), according to Dodds, R. Ali, A. & Galaski, K. (2016), has historically been developed based on a host community’s assets and objectives due to the fact that the "core of CBT planning has been to determine how best to use it as a development tool." As a result, the established CBT development model typically prioritizes community potential as supply at the expense of the market potential of tourism (demand), disregarding to a certain extent the commercial aspects of tourism. From this perspective, questions regarding product strategy, idea generation, business analysis, and how cross-sectoral knowledge production and exchange can strengthen the sustainability and viability of the CBT product have not yet been fully answered in academic literature. This paper builds on the academic literature regarding market access and is further supported by interviews and participant observation conducted in Brazil. This research indicates that these analyses should be complemented with additional questions about product development, capacity-building, knowledge co-production, collaborative networking, and more. The business life cycle of CBT could be considered a foundational pillar in understanding the business viability of community-based tourism projects, and therefore, the expected findings of this study include the proposal of an amended CBT model and practical recommendations that may be implemented into existing CBT projects.
Le tourisme communautaire (CBT), selon Dodds, R. Ali, A. et Galaski, K. (2016), a été largement développé sur la base des atouts et des objectifs d'une communauté en raison du fait que le en raison du fait que “le cœur de la planification de le tourisme communautaire a été de déterminer la meilleure façon de l'utiliser comme outil de développement” (p. 16). En conséquence, le développement du CBT a donné la priorité au potentiel communautaire (offre) au détriment du potentiel touristique (demande), sans tenir compte, dans une certaine mesure, des aspects commerciaux du tourisme. Dans cette perspective, les questions concernant la stratégie de produit, la génération d'idées, l'analyse commerciale et les moyens par lesquels la production et l'échange de connaissances intersectorielles peuvent renforcer la durabilité et la viabilité du produit CBT n'ont pas encore trouvé de réponse complète dans la littérature universitaire. Bien que les analyses concernant l'accès aux marchés soient abondantes dans la littérature (Dodds et al. 2016; Mitchell & Hall, 2005; Mitchell & Muckosy, 2008; Forstner, 2004; Iorio & Corsale, 2014), cet article, informé par des entretiens semi-structurés et l'observation des participants menée pendant le séjour de deux ans de l'auteur au Brésil, soutient que ces analyses devraient être complétées par des questions supplémentaires sur le développement de produits, la formation des capacités, la coproduction de connaissances, le réseautage collaboratif et plus encore. Le cycle de vie des entreprises du tourisme communautaire pourrait être considéré comme un pilier fondamental de la compréhension de la viabilité commerciale des projets de tourisme communautaire, et par conséquent, les conclusions attendues de cette étude incluent la proposition d'un modèle CBT modifié et des recommandations pratiques qui pourraient être mises en œuvre. dans les projets CBT existants.

Aeshna viridis, a dragonfly generally considered to be a specialist as it in most cases choosesStratiotes aloides as its habitat, have suffered badly from habitat loss and fragmentationsthroughout Europe under the last century as the human demand of land use have grown. It´sthereby considered near threatened on EU red list and is included in the Habitat Directive.This means that it is protected by EU law as all EU Member States is committed to protect,monitor and report back to EU the status of the species. Several European countries havedesigned protection plans for S. aloides to improve the preservation of A. viridis. My study inSouth and Central Sweden shows that the strong connection between A. viridis and S. aloidesmay not be consistent all over the distribution range of A. viridis, as my survey showed thatlarvae occur among other water plants when S. aloides is not present. Another aim in thisstudy was to evaluate the possibility to use occurrence data on A. viridis and S. aloides fromthe Species Observations System to monitor A. viridis distribution and dispersal. My studyimplies uncertainties of how well the datasets reflects reality and more research is necessarybefore clarifying if datasets could be a possible tool in conservation management of A. viridis.

In this paper we study the possibility of construction indicators-precursors relying on one of the most power-law tailed distributions – Levy’s stable distribution. Here, we apply Levy’s parameters for 29 stock indices for the period from 1 March 2000 to 28 March 2019 daily values and show their effectiveness as indicators of crisis states on the example of Dow Jones Industrial Average index for the period from 2 January 1920 to 2019. In spite of popularity of the Gaussian distribution in financial modeling, we demonstrated that Levy’s stable distribution is more suitable due to its theoretical reasons and analysis results. And finally, we conclude that stability α and skewness β parameters of Levy’s stable distribution which demonstrate characteristic behavior for crash and critical states, can serve as an indicator-precursors of unstable states.

In spite of popularity of the Gaussian distribution in financial modeling, we demonstrated that Levy’s stable distribution is more suitable due to its theoretical reasons and analysis results. We study the possibility of construction indicators- precursors relying on one of the most power-law tailed distributions - Levy’s stable distribution. Here, we apply moving window based procedure for calculation of Levy’s parameters - a - stability and /?- skewness for daily values of Dow Jones Industrial Average (from 1 March 2000 to 28 March 2019), the gold price (from 1 April 1968 to 8 May 2019) and Brent crude oil price (from 2 January 1986 to 6 May 2019) which show their effectiveness as indicators of crisis states. For the construction of the indicators, were selected time series of and, accordingly, for oil. Dow Jones’ time series has the period from 2 January 1920 to 2019. We conclude that a and /3 parameters of Levy’s stable distribution of the observed assets, which demonstrate characteristic behavior for crash and critical states, can serve as an indicator-precursors of the unstable states.

One major difficulty in developing fitness-for-purpose based flaw acceptance criteria for pipeline branch connections is the calculation of the stress distributions in the vicinity of the welds. Even with the latest computer aided modeling technologies, direct finite element modeling of branch connections using 3-D solid elements can be time consuming and cost prohibitive. Therefore, it is necessary to investigate the possibility of using more computationally-efficient finite element approaches to determine the stress distributions local to branch connections. This report describes work to develop flaw acceptance criteria based on fitness-for-purpose principles for branch connections in pipelines. The effort concentrated on investigating finite element modeling methodologies to predict accurately the stress distributions local to branch connections. These stress distributions can be used to develop fitness-for-purpose based flaw acceptance criteria that are consistent with those already developed for girth welds.

Dans quelle mesure l’augmentation des inégalités dans la productivité des entreprises se reflète-t-elle dans les inégalités de salaires ? La réponse dépend essentiellement du degré de transmission des différentiels de productivité en différentiels salariaux. Dans cette étude, les auteurs examinent cette question à partir des données de la Base de données canadienne sur la dynamique employeurs-employés (BDCEE) pour la période 2001-2019 et dégagent un ensemble de faits stylisés. De 2001 à 2019, on observe une hausse sans équivoque des inégalités de productivité entre les entreprises au Québec, un résultat conforme à ce qu'on observe dans plusieurs autres pays. Cette tendance à la hausse est plus importante au Québec qu'en Ontario. Il est intéressant de contraster cette hausse des inégalités de productivité à la baisse des inégalités de revenus. Une explication possible est que la transmission des différences de productivité en différences de revenus ait aussi diminué au cours de la période. Plusieurs possibilités pourraient expliquer cette diminution et l’une d’elles serait une diminution de la mobilité de la main-d’œuvre. Les auteurs examinent cette question en effectuant des décompositions de la croissance de la productivité pour le cas particulier du secteur manufacturier. Ils montrent que la croissance de la productivité dans ce secteur provient très majoritairement de la croissance de la productivité à l’intérieur de l’entreprise. La réallocation de main-d’œuvre et l’effet net d’entrée contribuent assez peu à la croissance de la productivité.

The possibility, first raised by Rudolf Hilferding, of stabilizing a capitalist economy through the operations of a ‘general cartel’, leaving only social and political ‘contradictions’ to disturb the functioning of the system, gave rise to a discussion among Marxists not only on whether such a stabilization was at all possible, but also on the nature and scope of those contradictions. This discussion had been anticipated in the 1890s in the work of the Polish Marxist Ludwik Krzywicki (1859 – 1941). He put forward the idea that, in a capitalist economy stabilized in this way, a state of ‘industrial feudalism’ would prevail, in which society would become stratified into social classes without the possibility of mobility between those classes. This analysis was extended in 1940s by Oskar Lange (1904-1965) as he attempted to make sense of the American New Deal and rediscovered in the 1950s by Tadeusz Kowalik (1926-2012). This paper explains the concept of industrial feudalism and argues that the main mechanism for such a stratification today is the unequal distribution of wealth, in the context of declining welfare provision.

This article demonstrates the comparative possibility of constructing indicators of critical and crash phenomena in the volatile market of cryptocurrency and developed stock market. Then, combining the empirical cross-correlation matrix with the Random Matrix Theory, we mainly examine the statistical properties of cross-correlation coefficients, the evolution of the distribution of eigenvalues and corresponding eigenvectors in both markets using the daily returns of price time series. The result has indicated that the largest eigenvalue reflects a collective effect of the whole market, and is very sensitive to the crash phenomena. It has been shown that introduced the largest eigenvalue of the matrix of correlations can act like indicators-predictors of falls in both markets.

Over 1,100 experts have shared with us their concerns about COVID-19 and COVID-impacted areas in the immediate and longer term future. This report outlines concerns about research and innovation. Experts have concerns about testing and diagnostics. Specifically about the number of tests being carried out, the availability of PCR tests and the accuracy of antigen tests. There are also concerns about vaccines. Experts want to know how the Government is speeding up vaccine development and note the possibility of annual vaccinations for some coronaviruses. Experts also think there should be more research on therapies for COVID-19 patients, including larger plasma therapy trials. Experts also have a range of practical concerns on international collaboration, the validation and approval of innovations, and even manufacturing and distribution of new products. Finally there are concerns about the impact of the outbreak on research. Experts worry about the quality of research and data collection and the access to COVID-19 research, noting that some research is not open access.

The article is devoted to the problem of incorporation geographic information systems (GIS) in world school practice. The authors single out the stages of GIS application in school geographical education based on the retrospective analysis of the scientific literature. The first stage (late 70 s – early 90s of the 20th century) is the beginning of the first educational GIS programs and partnership agreements between schools and universities. The second stage (mid-90s of the 20th century – the beginning of the 21st century) comprises the distribution of GIS-educational programs in European and Australian schools with the involvement of leading developers of GIS-packages (ESRI, Intergraph, MapInfo Corp., etc.). The third stage (2005–2012) marks the spread of the GIS school education in Eastern Europe, Asia, Africa and Latin America; on the fourth stage (from 2012 to the present) geographic information systems emerge in school curricula in most countries. The characteristics of the GIS-technologies development stages are given considering the GIS didactic possibilities for the study of school geography, as well as highlighting their advantages and disadvantages.
