Streszczenie:

The estimation and analysis of signals that have polynomial phase and constant or time-varying amplitudes with the addititve noise is considered in this dissertation.Much work has been undertaken on this problem over the last decade or so, and there are a number of estimation schemes available. The fundamental problem when trying to estimate the parameters of these type of signals is the nonlinear characterstics of the signal, which lead to computationally difficulties when applying standard techniques such as maximum likelihood and least squares. When considering only the phase data, we also encounter the well known problem of the unobservability of the true noise phase curve. The methods that are currently most popular involve differencing in phase followed by regression, or nonlinear transformations. Although these methods perform quite well at high signal to noise ratios, their performance worsens at low signal to noise, and there may be significant bias. One of the biggest problems to efficient estimation of these models is that the majority of methods rely on sequential estimation of the phase coefficients, in that the highest-order parameter is estimated first, its contribution removed via demodulation, and the same procedure applied to estimation of the next parameter and so on. This is clearly an issue in that errors in estimation of high order parameters affect the ability to estimate the lower order parameters correctly. As a result, stastical analysis of the parameters is also difficult. In thie dissertation, we aim to circumvent the issues of bias and sequential estiamtion by considering the issue of full parameter iterative refinement techniques. ie. given a possibly biased initial estimate of the phase coefficients, we aim to create computationally efficient iterative refinement techniques to produce stastically efficient estimators at low signal to noise ratios. Updating will be done in a multivariable manner to remove inaccuracies and biases due to sequential procedures. Stastical analysis and extensive simulations attest to the performance of the schemes that are presented, which include likelihood, least squares and bayesian estimation schemes. Other results of importance to the full estimatin problem, namely when there is error in the time variable, the amplitude is not constant, and when the model order is not known, are also condsidered.

Streszczenie:

zoo is an R package providing an S3 class with methods for indexed totally ordered observations, such as irregular time series. Its key design goals are independence of a particular index/time/date class and consistency with base R and the "ts" class for regular time series. This paper describes how these are achieved within zoo and provides several illustrations of the available methods for "zoo" objects which include plotting, merging and binding, several mathematical operations, extracting and replacing data and index, coercion and NA handling. A subclass "zooreg" embeds regular time series into the "zoo" framework and thus bridges the gap between regular and irregular time series classes in R.

Let K be a real quadratic number field. Let p be a prime which is inert in K. We denote the completion of K at the place p by Kp. Let ƒ > 1 be a positive integer coprime to p. In this thesis we give a p-adic construction of special elements u(r, ??) ∈ Kxp for special pairs (r, ??) ∈ (ℤ/ƒℤ)x x Hp where Hp = ℙ¹(ℂp) ℙ¹(ℚp) is the so called p-adic upper half plane. These pairs (r, ??) can be thought of as an analogue of classical Heegner points on modular curves. The special elements u(r, ??) are conjectured to be global p-units in the narrow ray class field of K of conductor ƒ. The construction of these elements that we propose is a generalization of a previous construction obtained in [DD06]. The method consists in doing p-adic integration of certain ℤ-valued measures on ??=ℤpxℤp pℤpxpℤp . The construction of those measures relies on the existence of a family of Eisenstein series (twisted by additive characters) of varying weight. Their moments are used to define those measures. We also construct p-adic zeta functions for which we prove an analogue of the so called Kronecker's limit formula. More precisely we relate the first derivative at s = 0 of a certain p-adic zeta function with -logₚ NKp/Qp u(r, ??). Finally we also provide some evidence both theoretical and numerical for the algebraicity of u(r, ??). Namely we relate a certain norm of our p-adic invariant with Gauss sums of the cyclotomic field Q (zetaf, zetap). The norm here is taken via a conjectural Shimura reciprocity law. We also have included some numerical examples at the end of section 18.

Streszczenie:

Classification problems with multiple classes and imbalanced sample sizes present a new challenge than the binary classification problems. Methods have been proposed to handle imbalanced learning, however most of them are specifically designed for binary classification problems. Multi-class imbalance imposes additional challenges when applied to time series classification problems, such as weather classification. In this thesis, we introduce, apply and evaluate a new algorithm for handling multi-class imbalanced problems involving time series data. Our proposed algorithm is designed to handle both multi-class imbalance and time series classification problems and is inspired by the Imbalanced Fuzzy-Rough Ordered Weighted Average Nearest Neighbor Classification algorithm. The feasibility of our proposed algorithm is studied through an empirical evaluation performed on a telecom use-case at Ericsson, Sweden where data from commercial microwave links is used for weather classification. Our proposed algorithm is compared to the currently used model at Ericsson which is a one-dimensional convolutional neural network, as well as three other deep learning models. The empirical evaluation indicates that the performance of our proposed algorithm for weather classification is comparable to that of the current solution. Our proposed algorithm and the current solution are the two best performing models of the study.

Streszczenie:

The problem of estimating latent or unobserved states of a dynamical system from observed data is studied in this thesis. Approximate filtering methods for discrete time series for a class of nonlinear systems are considered, which, in turn, require sampling from a partially specified discrete distribution. A new algorithm is proposed to sample from partially specified discrete distribution, where the specification is in terms of the first few moments of the distribution. This algorithm generates deterministic sigma points and corresponding probability weights, which match exactly a specified mean vector, a specified covariance matrix, the average of specified marginal skewness and the average of specified marginal kurtosis. Both the deterministic particles and the probability weights are given in closed form and no numerical optimization is required. This algorithm is then used in approximate Bayesian filtering for generation of particles and the associated probability weights which propagate higher order moment information about latent states. This method is extended to generate random sigma points (or particles) and corresponding probability weights that match the same moments. The algorithm is also shown to be useful in scenario generation for financial optimization. For a variety of important distributions, the proposed moment-matching algorithm for generating particles is shown to lead to approximation which is very close to maximum entropy approximation. In a separate, but related contribution to the field of nonlinear state estimation, a closed-form linear minimum variance filter is derived for the systems with stochastic parameter uncertainties. The expressions for eigenvalues of the perturbed filter are derived for comparison with eigenvalues of the unperturbed Kalman filter. Moment-matching approximation is proposed for the nonlinear systems with multiplicative stochastic noise.

Streszczenie:

Cette thèse analyse la "révolution associative" en Serbie, le boom des ong locales depuis la dissolution de la yougoslavie. Loin des vues normatives qui célèbrent les ONG comme incarnations démocratiques, il faut expliquer ce phénomène à travers ses liens dialectiques avec l'industrie de l'aide, l'économie politique mondiale et les projets néolibéraux de restructuration étatique. J'analyse tout d'abord ce que la démocratisation fait en pratique, les épistémologies du changement social qu'elle produit, la manière dont elle essentialise l'Histoire et suggère des techniques de soi comme forme d'intervention sociale. J'examine ensuite les politiques culturelles autour du cadre dominant "démocrates contre nationalistes" à travers le prisme analytique de classe: en exposant le cosmopolitisme pratique que les ONG de salon déploient comme stratégie de légitimation pour se consolider, et en analysant les "nationalstes" à travers des expériences de dépossessions symboliques et matérielles, je montre aussi que faire des "projets" déradicalise la production du savoir et l'action politique, en même temps qu'il produit un nouveau précariat. Enfin, je discute le conflit assumé entre ONG et état via la réforme de l'état providence. Je soutiens que les hiérarchies de pouvoir se situent plutôt entre une élite technocratique d'experts, circulant entre ONG-donateurs-état et les ONG et institutions publiques qui fournissent des services, stigmatisées à cause de leur "résistance" aux réformes. L'aide, je conclus, crée non seulement les conditions de sa propre reproduction institutionnelle, mais surtout, contribue à la reproduction sociale de systèmes mondiaux inégalement structurés
This thesis sets out to unpack the ‘‘associational revolution’’ in Serbia, the boom of local NGOs since the violent Yugoslav dissolution. Far from normative views, celebrating NGOs as democratic incarnations, we have to explain this phenomenon within its dialectical constitution with global systems of political economy, aid, and current neoliberal state restructuring. First, I analyze what democratization actually does, what kind of epistemologies of change it produces, how it collides to local political constellations, how it ‘pathologizes’ history and suggests technologies of the self as a form of social intervention. Second, I examine the politics of culture behind the dominant framework “Democrats vs. Nationalists” through the analytical prism of class: by depicting the ‘‘practical cosmopolitanism’’ that the salon NGOs deploy as a legitimizing strategy for consolidating power; and by analyzing the ‘‘nationalists’’ through class-based experiences of material and symbolic dispossessions. Third, I look at the art of NGOing; how project-making deradicalizes knowledge and political action; what labor patterns it produces through the formation of a local precariat. Finally, I discuss the overstated NGO-State clash through the welfare reform (outsourcing policy/provision). I argue that power hierarchies are instead to be drawn between a technocratic élite of experts, circulating among NGOs-donors-state, and nonprofit and public institutions in service provision, stigmatized for their “resistance”. Aid, I conclude, not only creates the conditions for its own institutional reproduction, but critically partakes to the social reproduction of unequally structured global systems

This thesis focuses on one of the most appreciated products of the Turkish Television, the TV Series'
production and labor process. Starting from the fact that the production side of this highly attention gathering media product hasn'
t received too much academic concern, by analyzing the workers of the sector, this point is tried to be illuminated. This thesis that analyzes TV series'
working conditions in the perspective of &ldquo
precarious employment&rdquo
departing from this framework, argues the workers of the industry are fragmented into two groups, &ldquo
creative&rdquo
and &ldquo
technical&rdquo
workers. In this context it indicates the creative workers not only as not being affected from the precarious employment conditions too much but also as the executor of the technical workers'
experience of precariousness in the production level.

Streszczenie:

This thesis is divided in two distinct parts. In the First part we are concerned with developing new statistical methodology for drawing Bayesian inference for partially observed stochastic epidemic models. In the second part, we develop a novel methodology for constructing a wide class of semi-parametric time series models. First, we introduce a general framework for the heterogeneously mixing stochastic epidemic models (HMSE) and we also review some of the existing methods of statistical inference for epidemic models. The performance of a variety of centered Markov Chain Monte Carlo (MCMC) algorithms is studied. It is found that as the number of infected individuals increases, then the performance of these algorithms deteriorates. We then develop a variety of centered, non-centered and partially non-centered reparameterisations. We show that partially non-centered reparameterisations often offer more effcient MCMC algorithms than the centered ones. The methodology developed for drawing eciently Bayesian inference for HMSE is then applied to the 2001 UK Foot-and-Mouth disease outbreak in Cumbria. Unlike other existing modelling approaches, we model stochastically the infectious period of each farm assuming that the infection date of each farm is typically unknown. Due to the high dimensionality of the problem, standard MCMC algorithms are inefficient. Therefore, a partially non-centered algorithm is applied for the purpose of obtaining reliable estimates for the model's parameter of interest. In addition, we discuss similarities and differences of our fndings in comparison to other results in the literature. The main purpose of the second part of this thesis, is to develop a novel class of semi-parametric time series models. We are interested in constructing models for which we can specify in advance the marginal distribution of the observations and then build the dependence structure of the observations around them. First, we review current work concerning modelling time series with fixed non-Gaussian margins and various correlation structures. Then, we introduce a stochastic process which we term a latent branching tree (LBT). The LBT enables us to allow for a rich variety of correlation structures. Apart from discussing in detail the tree's properties, we also show how Bayesian inference can be carried out via MCMC methods. Various MCMC strategies are discussed including non-centered parameterisations. It is found that non-centered algorithms significantly improve the mixing of some of the algorithms based on centered reparameterisations. Finally, we present an application of this class of models to a real dataset on genome scheme data.

Streszczenie:

The response of a karst aquifer to storm events is often faster and more severe than that of a non-karst aquifer. This distinction is often problematic for planners and municipalities, because karst flooding does not typically occur along perennial water courses; thus, traditional flood management strategies are usually ineffective. The City of Bowling Green (CoBG), Kentucky is a representative example of an area plagued by karst flooding. The CoBG, is an urban karst area (UKA), that uses Class V Injection Wells to lessen the severity of flooding. The overall effectiveness, siting, and flooding impact of Injection Wells in UKA’s is lacking; their influence on groundwater is evident from decades of recurring problems in the form of flooding and groundwater contamination. This research examined Class V Injection Wells in the CoBG to determine how Injection Well siting, design, and performance influence urban karst hydrology. The study used high-resolution monitoring, as well as hydrologic modeling, to evaluate Injection Well and spring responses during storm and baseflow conditions. In evaluating the properties of the karst aquifer and the influences from the surrounding environment, a relationship was established between precipitation events, the drainage capacity of the Injection Wells, and the underlying karst system. Ultimately, the results from this research could be used to make sound data-driven policy recommendations and to inform stormwater management in UKAs.

Streszczenie:

This thesis is a study of serial viewing among women in middle-families in two Indian cities carried out in 2007. It explores women’s engagement with a new brand of serial narratives that centralizes the traditional Hindu joint family and places women at the centre of the family as nurturer and custodian of traditional values. This return to the traditional, the thesis proposes, marks a new conjunctural moment in the evolution of Indian television. This new conjunctural moment, characterized by competitive attempts among private and transnational cable and satellite television to Indianize content, the unprecedented growth of vernacular television and consequently the national circulation of traditionally inflected serials, has come to represent the feminisation of television in India. The manner in which differentially located women engage with these narratives of idealized family and womanhood suggests certain specific gendered ways in which television mediates women’s discursive access to and performance within both family and civic space. This thesis argues that the feminisation of television in India helps extend the ideal of a familial womanhood on to the civic space, limiting women’s access to alternative, oppositional forms of civic belonging and citizenship.

Title: “I hope to be your uterus” - A multimodal analysis on surrogacy in scenes from The Handmaid’s tale and Friends Surrogacy is a widely discussed subject both internationally and in Sweden. The opinions on whether it should be legalized or not differ from country to country, which is reflected in how they implement their different laws on the subject. The main issues in the debates about surrogacy is whether a legalization of altruistic surrogacy would lead to safe methods within the medical care and stop the expansion of illegal markets or if there’s risks of opening the doors to a bigger commercial market. Parallel to the political discussion and opinions on the subject, the portrayal of surrogacy has appeared within popular culture, as in TV-series, for a period of time. It can be found in different genres like drama and comedy since the 90s, which makes the subject interesting to observe. The purpose of this essay is to study how the topic of surrogacy is portrayed in two different genres in the TV-series Friends and The Handmaid’s tale. For this purpose we use multimodal analysis to answer if there are similarities and/or differences in the portrayal of surrogacy within our research material. The theoretical framework is based on Richard Dyers theories on stereotypes, Carol Patemans ideas of ‘the sexual contract’ and Brooke Weihe Edges studies on the representation of women in different movie genres amongst others. Our study shows that even if the genres vary there are stereotypical structures in how both infertile women and surrogate mothers are presented to the audience.

Pełny tekst źródła

Streszczenie:

To be effective, a linear congruential random number generator (LCG) should produce values that are (a) uniformly distributed on the unit interval (0,1) excluding endpoints and (b) substantially free of serial correlation. It has been found that many statistical methods produce inflated Type I error rates for correlated observations. Theoretically, independently seeding an LCG under the following conditions attenuates serial correlation: (a) simple random sampling of seeds, (b) non-replicate streams, (c) non-overlapping streams, and (d) non-adjoining streams. Accordingly, 4 algorithms (each satisfying at least 1 condition) were developed: (a) zero-leap, (b) fixed-leap, (c) scaled random-leap, and (d) unscaled random-leap. Note that the latter satisfied all 4 independent seeding conditions. To assess serial correlation, univariate and multivariate simulations were conducted at 3 equally spaced intervals for each algorithm (N=24) and measured using 3 randomness tests: (a) the serial correlation test, (b) the runs up test, and (c) the white noise test. A one-way balanced multivariate analysis of variance (MANOVA) was used to test 4 hypotheses: (a) omnibus, (b) contrast of unscaled vs. others, (c) contrast of scaled vs. others, and (d) contrast of fixed vs. others. The MANOVA assumptions of independence, normality, and homogeneity were satisfied. In sum, the seeding algorithms did not differ significantly from each other (omnibus hypothesis). For the contrast hypotheses, only the fixed-leap algorithm differed significantly from all other algorithms. Surprisingly, the scaled random-leap offered the least difference among the algorithms (theoretically this algorithm should have produced the second largest difference). Although not fully supported by the research design used in this study, it is thought that the unscaled random-leap algorithm is the best choice for independently seeding the multiplicative congruential random number generator. Accordingly, suggestions for further research are proposed.

Streszczenie:

As more IoT devices enter the market it becomes increasingly important to develop reliable and adaptive ways of dealing with the data they generate. These must address data quality and reliability. Such solutions could benefit both the device producers and their customers who, as a result, could receive faster and better customer support services. Thus, this project's goal is twofold. First, it is to identify faulty data points generated by such devices. Second, it is to evaluate whether the knowledge gained from available/known sensors and appliances is transferable to other sensors on similar devices. This would make it possible to evaluate the behaviour of new appliances as soon as they are first switched on, rather than after sufficient data from them has been collected. This project uses time series data from three appliances: washing machine, washer&dryer and refrigerator. For these, two solutions are developed and tested: one for categorical and another for numerical variables. Categorical variables are analysed using the Average Value Frequency and the pure frequency of state-transition methods. Due to the limited number of possible states, the pure frequency proves to be the better solution, and the knowledge gained is transferred from the source device to the target one, with moderate success. Numerical variables are analysed using a One-class Support Vector Machine pipeline, with very promising results. Further, learning and forgetting mechanisms are developed to allow for the pipelines to adapt to changes in appliance patterns of behaviour. This includes a decay function for the numerical variables solution. Interestingly, the different weights for the source and target have little to no impact on the quality of the classification.
Nya IoT-enheter träder in på marknaden så det blir allt viktigare att utveckla tillförlitliga och anpassningsbara sätt att hantera de data de genererar. Dessa bör hantera datakvalitet och tillförlitlig- het. Sådana lösningar kan gynna båda tillverkarna av apparater och deras kunder som som ett resultat kan dra nytta av snabbare och bättre kundsupport / tjänster. Således har detta projekt två mål. Det första är att identifiera felaktiga datapunkter som genereras av sådana enheter. För det andra är det att utvärdera om kunskapen från tillgängliga / kända sensorer och apparater kan överföras till andra sensorer på liknande enheter. Detta skulle göra det möjligt att utvärdera beteendet hos nya apparater så snart de slås på första gången, snarare än efter att tillräcklig information från dem har samlats in. Detta projekt använder tidsseriedata från tre apparater: tvättmaskin, tvättmaskin och torktumlare och kylskåp. För dessa utvecklas och testas två lösningar: en för kategoriska variabler och en annan för numeriska variabler. De kategoriska variablerna analyseras med två metoder: Average Value Frequency och den rena frekvensen för tillståndsövergång. På grund av det begränsade antalet möjliga tillstånd visar sig den rena frekvensen vara den bättre lösningen, och kunskapen som erhålls överförs från källanordningen till målet, med måttlig framgång. De numeriska variablerna analyseras med hjälp av en One-class Support Vector Machine-pipeline, med mycket lovande resultat. Vidare utvecklas inlärnings- och glömningsmekanismer för att möjliggöra för rörledningarna att anpassa sig till förändringar i apparatens beteendemönster. Detta inkluderar en sönderfallningsfunktion för den numeriska variabellösningen. Intressant är att de olika vikterna för källan och målet har liten eller ingen inverkan på kvaliteten på klassificeringen.

Streszczenie:

This study explores the relationship between literature and society against the background of the emergence in the 1930s and 1940s in South Africa of a form of Afrikaner nationalism that was spearheaded by members of the Afrikaner petty bourgeoisie and intelligentsia and a subsequent expansion in Afrikaans literary production. It addresses problems of explanation in Afrikaner nationalism by focusing attention on the question of culture, the field of imagination and the domain of everyday life. In particular, the study examines the Keurboslaan series - a series of schoolboy stories aimed at juvenile readers - by Stella Blakemore, and traces the production, circulation and critical reception of the twenty titles in the series. The first title in this series was published in 1941 and the series has been reprinted several times over a number of decades and as recently as 1997. Drawing on the work of Benedict Anderson, this study illuminates the link between the emergence of print capitalism and the production of popular fiction on the one hand and nationalism on the other. Whilst this is a link that is not often explored, an analysis of the Keurboslaan series illustrates that the study of popular fiction can illuminate the practices through which nationalism gains popular support. It is argued that the Keurboslaan series produced a narrative of the Afrikaner ‘nation’ in popular fiction, but that this narrative was not authenticated by the intelligentsia and petty bourgeoisie who were the driving forces behind Afrikaner nationalism and its contents. It is further argued that this ‘narrative of nation’ circulated alongside more official narratives of the ‘nation’ espoused in discourses of religion, science and literature published in Afrikaans. The narrative of ‘nation’ in Keurboslaan – whilst sharing many similarities with official narratives in other discourses – but also differs from those discourses in important respects. It is argued that the popular series was influential precisely because it imagined the Afrikaner ‘nation’ in very different ways and on different terms from those discourses. Moreover, the form in which this narrative was produced, that is popular youth literature, appealed to readers of Afrikaans who were in search of escapist fiction. For these readers, the Keurboslaan series helped to give shape to and created new possibilities for interpreting the world that they inhabited. Reading the school as a corollary of the ‘nation’, it is argued that the narrative of the nation in Keurboslaan series explores the boundaries between the self and the other and posits the self as a danger to the self, resulting in an emphasis on the need to discipline the self. This kind of analysis also creates the space for examining in what ways ideas and identities about ‘race’, gender, sexuality, class and ‘nation’ are constructed in the texts. Yet, the study maintains that whilst the Keurboslaan series contributed to creating a space in which a particular understanding of the self and the world becomes possible, and whereas the reader is not conceived of as a completely free agent that can derive simply any meaning from the text, the study and its theoretical underpinnings do not fully account for individual readers’ engagement with popular texts and the ways in which reading strategies and habits can generate different, ambiguous or inconclusive meanings for readers. It is suggested that a study of popular texts and Afrikaner nationalism employing theories of reading and the reader will complement this analysis.

Streszczenie:

Parallel robots with configurable platform are a class of parallel robots in which the end-effector is a closed-loop flexible chain of rigid links. We have developed a 5-RRR planar mechanism that features a flexible 5-bar chain as end-effector. The angles between adjacent sides of this chain can be controlled through the actuated revolute joints attached to the base of the mechanism. This thesis consists in the geometrical design of n-RRR planar parallel robots and in the study of the Direct Kinematics for 4-, 5- and 6-RRR mechanisms using Bilateration, a method that greatly reduces the computational time for the kinematic analysis. The next step is the singularity analysis for the n-RRR robot architectures; finally, in the last part of this thesis we present the results from experimental tests that have been performed on a 5-RRR robot prototype.

Streszczenie:

L'étude des surfaces continentales est devenue ces dernières années un enjeu majeur à l'échelle mondiale pour la gestion et le suivi des territoires, notamment en matière de consommation des terres agricoles et d'étalement urbain. Dans ce contexte, les cartes d'occupation du sol caractérisant la couverture biophysique des terres émergées jouent un rôle essentiel pour la cartographie des surfaces continentales. La production de ces cartes sur de grandes étendues s'appuie sur des données satellitaires qui permettent de photographier les surfaces continentales fréquemment et à faible coût. Le lancement de nouvelles constellations satellitaires - Landsat-8 et Sentinel-2 - permet depuis quelques années l'acquisition de séries temporelles à hautes résolutions. Ces dernières sont utilisées dans des processus de classification supervisée afin de produire les cartes d'occupation du sol. L'arrivée de ces nouvelles données ouvre de nouvelles perspectives, mais questionne sur le choix des algorithmes de classification et des données à fournir en entrée du système de classification. Outre les données satellitaires, les algorithmes de classification supervisée utilisent des échantillons d'apprentissage pour définir leur règle de décision. Dans notre cas, ces échantillons sont étiquetés, \ie{} la classe associée à une occupation des sols est connue. Ainsi, la qualité de la carte d'occupation des sols est directement liée à la qualité des étiquettes des échantillons d'apprentissage. Or, la classification sur de grandes étendues nécessite un grand nombre d'échantillons, qui caractérise la diversité des paysages. Cependant, la collecte de données de référence est une tâche longue et fastidieuse. Ainsi, les échantillons d'apprentissage sont bien souvent extraits d'anciennes bases de données pour obtenir un nombre conséquent d'échantillons sur l'ensemble de la surface à cartographier. Cependant, l'utilisation de ces anciennes données pour classer des images satellitaires plus récentes conduit à la présence de nombreuses données mal étiquetées parmi les échantillons d'apprentissage. Malheureusement, l'utilisation de ces échantillons mal étiquetés dans le processus de classification peut engendrer des erreurs de classification, et donc une détérioration de la qualité de la carte produite. L'objectif général de la thèse vise à améliorer la classification des nouvelles séries temporelles d'images satellitaires à hautes résolutions. Le premier objectif consiste à déterminer la stabilité et la robustesse des méthodes de classification sur de grandes étendues. Plus particulièrement, les travaux portent sur l'analyse d'algorithmes de classification et la sensibilité de ces algorithmes vis-à-vis de leurs paramètres et des données en entrée du système de classification. De plus, la robustesse de ces algorithmes à la présence des données imparfaites est étudiée. Le second objectif s'intéresse aux erreurs présentes dans les données d'apprentissage, connues sous le nom de données mal étiquetées. Dans un premier temps, des méthodes de détection de données mal étiquetées sont proposées et étudiées. Dans un second temps, un cadre méthodologique est proposé afin de prendre en compte les données mal étiquetées dans le processus de classification. L'objectif est de réduire l'influence des données mal étiquetées sur les performances de l'algorithme de classification, et donc d'améliorer la carte d'occupation des sols produite
Land surface monitoring is a key challenge for diverse applications such as environment, forestry, hydrology and geology. Such monitoring is particularly helpful for the management of territories and the prediction of climate trends. For this purpose, mapping approaches that employ satellite-based Earth Observations at different spatial and temporal scales are used to obtain the land surface characteristics. More precisely, supervised classification algorithms that exploit satellite data present many advantages compared to other mapping methods. In addition, the recent launches of new satellite constellations - Landsat-8 and Sentinel-2 - enable the acquisition of satellite image time series at high spatial and spectral resolutions, that are of great interest to describe vegetation land cover. These satellite data open new perspectives, but also interrogate the choice of classification algorithms and the choice of input data. In addition, learning classification algorithms over large areas require a substantial number of instances per land cover class describing landscape variability. Accordingly, training data can be extracted from existing maps or specific existing databases, such as crop parcel farmer's declaration or government databases. When using these databases, the main drawbacks are the lack of accuracy and update problems due to a long production time. Unfortunately, the use of these imperfect training data lead to the presence of mislabeled training instance that may impact the classification performance, and so the quality of the produced land cover map. Taking into account the above challenges, this Ph.D. work aims at improving the classification of new satellite image time series at high resolutions. The work has been divided into two main parts. The first Ph.D. goal consists in studying different classification systems by evaluating two classification algorithms with several input datasets. In addition, the stability and the robustness of the classification methods are discussed. The second goal deals with the errors contained in the training data. Firstly, methods for the detection of mislabeled data are proposed and analyzed. Secondly, a filtering method is proposed to take into account the mislabeled data in the classification framework. The objective is to reduce the influence of mislabeled data on the classification performance, and thus to improve the produced land cover map

Streszczenie:

Viktiga frågor konstrueras på olika sätt, inom fiktion, utefter producentens uppfattningar om världen. Genom att undersöka maktrelationerna kan man ta reda på vilken betydelse makt har i viktiga frågor som hat, ras, klass. Syftet med studien har varit att undersöka och analysera hur maktrelationer opererar i den populärkulturella tv-serien Orange Is the New Black. För att utföra studien analyserades ett avsnitt, det sjunde ur säsong 4, som släpptes i juni år 2016. De frågeställningar som ställdes till materialet var: Hur konstrueras maktrelationer inom fältet Orange Is the New Black?”, ”I vilka situationer är dessa maktrelationer tydliga?”, samt ”Är dessa situationer positiva/negativa och i sådana fall på vilka sätt?”. Dessa frågeställningar utformades för att ge en helhetsbild av maktrelationerna inom avsnittet. För att utföra studien tillämpades Pierre Bourdieus klassperspektiv, där begreppen fält, habitus och kapital användes. I uppsatsen diskuterades även Marx definition av begreppet klass, då klass-begreppet är mest associerat till honom. Även Goffmans teori angående stigma användes för att kunna gå in med en förståelse av vad de utsatta kan ha för attribut som kan påverka hur andra ser på dem. För att utföra studien tillämpades även Bourdieus metodologi. Analysen visade att maktrelationer konstrueras på olika sätt. Genom att producenten skapar situationer där karaktärerna tävlar om makt och kapital får tittaren se vilken betydelse makt har inom viktiga frågor. Kamper om makt och kapital visades på flera olika sätt. Slutsatsen som drogs var att maktrelationer konstrueras på flera olika sätt, att dessa händelser och situationer inte enbart är negativa, utan även positiva och hur situationerna konstrueras kan påverka människors tankar då det är en populärkulturell serie som når ut till en massa.
Important subjects in fictional tv-series are being constructed in different ways, depending on the producers view on the world. By examining power relationships you can find out what role power plays within subjects like hate, race and class. The purpose of this study was to analyze how power relationships operate on the popular cultural tv-show Orange Is the New Black. The seventh episode of season 4 was analyzed, which aired in June 2016. The questions that were asked to the material were: ”How are power relationships constructed within the field of Orange Is the New Black?”, ”In what situations are these power relationships clear?”, and ”Are these situations positive/negative, and if so, in which way?”. These questions were asked to get the whole picture of the power relationships within the episode. In this study the theory of class by Pierre Bourdieu was used, where the concept of field, capital and habitus took a lot of space. Marx definition of class was also discussed in the study, because class is mostly associated with him. Another theory that was discussed was Erving Goffman’s theory about stigma. The purpose of using this theory was to understand what attributes a prisoner can have that could affect how other people view them. In this study, the methodology of Bourdieu was used. The analysis showed that power relationships are being constructed in different ways. When the producer creates situations where the characters are fighting about power and capital, the viewer is able to see how power is operating within important questions. Fights about capital and power were shown in different ways. The conclusion that was made is that power relationships are being constructed in different ways, that these situations are both positive and negative and that they can affect peoples mind due to being a popular cultural tv-show that is seen by many.

The present work focuses on one the most traditional constituent schools of the public schools in São Paulo: The Boards of Class and Serie. Concented to be rooms of collective evaluation with potencial to provide the construction or reconstruction of the Pedagogical Proposal, were reduced, in practice, to mere bureaucratic rituals, while many schools disconsider the legal demand that determines the participation of students in their instances. The study had as aim identification and analisis of the factors that interfere directly and indirectly in the implementation of participation of students and their parents in these constituent schools. Of empirical nature, the research is supported by the analisis of Maurício Tragtemberg, to whom the school works as a center of reproduction of relationship of production, while selects the students through what is named bureaucratic pedagogy . It was focused on one of the schools that included effectively students and their parents in the Boards of Class and Serie, confronting, during the process, the conflicts inherent to bureaucratic structure of the scholar institution. We have perceived that the practice of the majority of the professionals of schools, specially of teachers, keep themselves pierced by traditional representations of patrimonialist character, in the sense pointed out by Weber, in contrast to the effort of the team of direction in deepening the participation of the students and their parents in constituent schools. The traditional representations cohabit and integrate to bureaucratic structure of public school, consisting in one of the principal obstacles to effective participation. We have decided for participant observation, in virtue of our double insertion in this process: as through lecture in public school of the state net as of the drill of a post of specialist in Board of Directors of Education methodological procedure which has allowed us a range of data from various schools, permitting the establishment of some relevant comparisons to the proposed study.(AU)
O presente trabalho enfoca um dos colegiados mais tradicionais das escolas públicas no Estado de São Paulo: os Conselhos de Classe e Série. Concebidos para serem espaços de avaliação coletiva com potencial para propiciar a construção ou re-construção da Proposta Pedagógica, foram reduzidos, na prática, a meros rituais burocráticos, à medida que muitas escolas desconsideram a exigência legal que determina a participação dos alunos em suas instâncias. O estudo teve por objetivo a identificação e a análise dos fatores que interferem direta e indiretamente na implementação da participação dos alunos e seus pais nestes colegiados. De natureza empírica, a pesquisa apóia-se nas análises de Maurício Tragtemberg, para quem a escola funciona como centro de reprodução das relações de produção, à medida que seleciona os alunos através do que denomina pedagogia burocrática . Concentrou-se numa das escolas que incluíram efetivamente alunos e pais nos Conselhos de Classe e Série, confrontando, durante o processo, os conflitos inerentes à estrutura burocrática da instituição escolar. Constatamos que as práticas da maioria dos professores da escola pesquisada mantêm-se permeadas pelas representações tradicionais de cunho patrimonialista, no sentido apontado por Weber, em contradição ao esforço da equipe de direção em aprofundar a participação dos alunos e seus pais nos colegiados. As representações tradicionais convivem e integram-se à estrutura burocrática da escola pública, constituindo-se num dos principais obstáculos à efetiva participação. Optamos pela observação participante, em virtude de nossa dupla inserção nesse processo: tanto através da docência em escola pública da rede estadual, quanto do exercício de um cargo de especialista no âmbito da Diretoria de Ensino procedimento metodológico que nos permitiu dispor de dados de várias escolas, possibilitando o estabelecimento de algumas comparações pertinentes para o estudo proposto.(AU)

Estudamos tópicos relacionados a zeros de séries de Dirichlet e de funções inteiras. Boa parte da tese é voltada à localização de zeros de séries de Dirichlet via critérios de densidade. Estabelecemos o critério de Nyman-Beurling para uma ampla classe de séries de Dirichlet e o critério de Báez-Duarte para L-funções de Dirichlet em semi-planos R(s)>1/2, para p ∈ (1,2], bem como para polinômios de Dirichlet em qualquer semi-plano R(s)>r. Um análogo de uma cota inferior de Burnol relativa ao critério de Báez-Duarte foi estabelecido para polinômios de Dirichlet. Uma das ferramentas principais na prova deste último resultado é a solução de um problema extremo natural para polinômios de Dirichlet inspirado no resultado de Báez-Duarte. Provamos que os sinais dos coeficientes de Maclaurin de uma vasta subclasse de funções inteiras da classe de Laguerre-Pólya possuem um comportamento regular.
We study topics related to zeros of Dirichlet series and entire functions. A large part of the thesis is devoted to the location of zeros of Dirichlet series via density criteria. We establish the Nyman-Beruling criterion for a wide class of Dirichlet series and the Báez-Duarte criterion for Dirichlet L-functions in the semi-plane R(s)>1/p, for p ∈ (1,2], as well as for zeros of Dirichlet polynomials in any semi-plane R(s)>r. An analog for the case of Dirichlet polynomials of a result of Burnol which is closely related to Báez-Duarte’s one is also established. A principal tool in the proof of the latter result is the solution of a natural extremal problem for Dirichlet polynomials inspired by Báez-Duarte’s result. We prove that the signs of the Maclaurin coefficients of a wide class of entire functions that belong to the Laguerre-Pólya class posses a regular behavior.

Notre étude s’intitule variations de formes dans la langue Mbochi (bantu C25). Elle s’inscrit dans le cadre de la linguistique historique bantu.A travers une analyse dialectométrique, elle identifie et localise les dix parlers mbochi. Elle montre que le mbochi est une langue bantu parlée dans le nord de la République du Congo, dans le département de la Cuvette (dans les districts de Boundji, Ngoko, Tchikapika et Oyo) et celui des Plateaux (dans les districts d’Ongogni, Ollombo, Abala, Alembe). Il compte dix dialectes (Olee, Mbonzi, Tsambitso, Ngilima, Bokwele, Bonyala, Ngae, Obaa, Eboyi et Ondinga). Visant une meilleure compréhension des mécanismes linguistiques qui sous-tendent la diversification linguistique dans le pays mbochi, notre analyse se focalise sur les variations phoniques, morphologiques et lexicales qui s’opèrent d’un dialecte mbochi à un autre. Elle dégage les divergences et les convergences entre les différents parlers. Aussi présente-t-elle une description phonologique et morphologique des parlers mbochi actuels (synchronie). Elle examine les correspondances phonologiques et morphologiques ainsi que les réflexes du proto-bantu en mbochi avant de procéder à la reconstruction des phonèmes et des morphèmes du proto-mbochi, mère hypothétique des parlers actuels.La présente étude divise les parlers mbochi en trois principaux sous-groupes selon leurs convergences phonologiques et morphologiques. Elle montre l’impact de la proximité géographique, du contact des langues dans la diversification de celles-ci
Our study entitled “variations of forms in Mbochi language (Bantu C25)” is considered as part of the Bantu historical linguistics. It identifies and locates the ten Mbochi dialects through a dialectometric analysis. It shows that Mbochi is a Bantu language spoken in the northern part of Republic of Congo, mainly in the Cuvette (in the districts of Boundji, Ngoko, Tchikapika and Oyo) and Plateau (in the Ongogni districts Ollombo, Abala Alembé) departments. It has ten dialects (Olee, Mbonzi, Tsambitso, Ngilima, Bokwele, Bonyala, Ngae, Obaa, Eboyi and Ondinga).Our analysis targets a better understanding of the underlying language mechanisms of linguistic diversity of Mbochi and is focused on sound, morphological and lexical variations from one dialect to another. It highlights the differences and similarities between these dialects. It also presents a phonological and morphological description of the current Mbochi dialects (synchrony). It examines the phonological and morphological correspondences to the proto-bantu before reconstructing the phonemes and morphemes of proto-Mbochi, the hypothetical source of the current Mbochi dialects.This study divides the Mbochi dialects into three main sub-groups according to their phonological and morphological similarities. It shows both the impact of geographical proximity and that of language contact in the diversification of these dialects

Streszczenie:

La construction à verbes en série (CVS) du chinois a fait l'objet de multiples débats, concernant sa définition, l'inventaire des constructions qui la composent. Parmi les multiples fonctions reconnues dans les descriptions de la CVS se trouve celle d'exprimer le but. Or en comparaison avec la proposition subordonnée de but, les CVS exprimant le but sont restées largement inexplorées. Nous proposons tout d'abord une définition de la CVS de but, s’appuyant sur plusieurs critères, puis nous nous livrons à une analyse syntaxique et sémantique de la CVS de but, et nous la comparons avec la proposition subordonnée de but. Ce travail d'analyse de la CVS de but s'appuie sur un corpus de phrases recueillies dans des romans et séries télévisées en chinois moderne.La thèse consacre un chapitre à la CVS de but constituée d'un verbe de déplacement et d'un syntagmeverbal de but, considérée dans la littérature comme prototypique, où sont aussi abordées des questions liées aux verbes au sens de « venir » et de « aller » dans diverses constructions connexes. Un autre chapitre traite de la construction correspondante en français et dans d'autres langues européennes. Nous montrons par ce travail que la CVS de but du chinois est plus intégrée que la phrase complexe exprimant le but sur le plan syntaxique et sémantique, mais moins intégrée que la construction correspondan te du français.Nous espérons contribuer, par ce travail, aux études sur la CVS du chinois moderne et sur l'expression du but dans cette langue, ainsi qu'au domaine de la linguistique contrastive entre le chinois et le français
In Chinese, the serial verb construction (SVC) has been the center of many debates, regarding both its definition and the inventory of sentences which should be characterized as SVCs. Among the many functions of SVCs documented in the literature is that of expressing purpose. However, purpose SVCs are underdescribed in the literature, which has mainly focused on purpose subordinate clauses in complex sentences. We first propose a definition of purpose SVCs based on a set of formal and semantic criteria, then we carry out syntactic and semantic analysis of purpose SVC, and compare it with the subordinate purpose clause in a complex sentence. This analysis is based on a corpus of sentences collected in modern Chinese novels and television series.We also address in a specific chapter issues related to motion verbs meaning "to come" and "to go" when they are combined with a purpose VP, which are usually considered as prototypical SVCs. This allows us to discuss a number of related constructions sometimes analyzed as SVCs in the literature. Another chapter deals with the corresponding construction in French and in other European languages. We show that the C hinese purpose SVC is syntactically and semantically more integrated than the purpose clause in a complex sentence, but is less integrated than the corresponding French construction.We hope to contribute, through this work, to the research on modern Chinese CVS and on the constructions expressing purpose in this language, as well as to Chinese-French contrastive linguistics

Le volume, la valeur, la variété, la vélocité et la véracité définissent les cinq caractéristiques du Big Data qui représentent une complexité fondamentale pour de nombreux algorithmes d’apprentissage automatique, tels que le clustering, la reconnaissance d’images et d’autres techniques d’apprentissage modernes. Avec ces données volumineuses, les estimations d’hyperparamètres ne prennent pas la forme de la moyenne de l’échantillon (non linéaire), mais celle de la forme de la moyenne sur m-tuples, appelée l’estimateur U-statistique. Nous considérons dans cette thèse la collection de U-statistiques, connue sous le nom de U-processus, pour deux types de variables dépendantes, les données Markoviennes et les variables aléatoires localement stationnaires. Ainsi, nous avons divisé notre travail en deux parties pour aborder chaque type indépendamment. Dans la première partie, nous considérons les variables Markoviennes. Nous nous concentrons particulièrement sur les développements de U-processus bootstrappés dans un cadre de Harris. L’idée fondamentale utilisée repose sur les méthodes régénératives consistant essentiellement à diviser l’échantillon en blocs de données indépendants et identiquement distribués (i.i.d.), où chaque bloc correspond à des segments de chemin entre deux visites à un atome appelé A formant une séquence de renouvellement. Nous caractérisons les propriétés limites pour les U-processus indexés par des classes de fonctions uniformément bornées et non bornées. Nous montrons la consistance du bootstrap dans ce cadre. L’approche du bootstrap permet de contourner les problèmes fréquemment rencontrés pour l’évaluation des lois limites dépendants d’une manière complexe de paramètres inconnus. La technique de bootstrap que nous utilisons dans cette thèse est le bootstrap de renouvellement, où l’échantillon bootstrap est formé par rééchantillonnage à partir des blocs. Comme les blocs non bootstrapés sont indépendants, une partie des preuves se réduit au cas i.i.d. Les principales difficultés sont liées à la taille aléatoire des blocs rééchantillonnés, ce qui crée un problème non trivial de temps d’arrêts aléatoires, constituant un des grands obstacles de la généralisation de la théorie dans notre contexte. Pour contourner cette difficulté, nous avons utilisé comme étape intermédiaire la substitution du temps d’arrêt aléatoire par son espérance. La convergence faible des U-processus bootstrappés est très délicate dans notre cadre, en particulier l’équicontinuité en utilisant la comparaison avec le U-processus initial. Nous avons étendu les résultats susmentionnés au cas où le degré du U-processus croît avec la taille de l’échantillon n, le noyau variant dans une classe de fonctions. Nous avons caractérisé la convergence faible pour le bootstrap de renouvellement pour le U-processus à degré infini en faisant usage de la technique de découplage combinée avec des techniques de symétrisation. Enfin, nous considérons un bootstrap pondéré échangeable des U-processus empiriques. Dans la deuxième partie de cette thèse, les données dépendantes sont représentées par des fonctions aléatoires localement stationnaires. Propulsés par la représentation croissante des séries temporelles par des données fonctionnelles ou courbes, et le comportement non stationnaire de ces dernières, nous nous sommes intéressés au U-processus conditionnel des séries temporelles fonctionnelles localement stationnaires. Plus précisément, nous avons étudié la convergence faible des U-processus conditionnels, indexée par des classes de fonctions, dans le cadre de données fonctionnelles localement stationnaires. Nous avons caractérisé la convergence faible dans les deux cas lorsque la classe de fonctions est bornée ou non bornée satisfaisant certaines conditions de moment
The world is producing 2.5 quintillion bytes daily, known as big data. Volume, value, variety, velocity, and veracity define the five characteristics of big data that represent a fundamental complexity for many machine learning algorithms, such as clustering, image recognition, and other modern learning techniques. With this large data, hyperparameter estimations do not take the form of the sample mean (not linear). Instead, they takethe form of average over m-tuples, known as the U-statistic estimator in probabilityand statistics. In this work, we treat the collection of U-statistics, known as the Uprocess,for two types of dependent variables, the Markovian data, and locally stationary random variables. Thus, we have divided our work into two parts to address each type independently.In the first part, we deal with Markovian data. The approach relies on regenerative methods, which essentially involve dividing the sample into independent and identically distributed (i.i.d.) blocks of data, where each block corresponds to the path segments between two visits of an atom called A, forming a renewal sequence. We derive the limiting theory for Harris recurrent Markov chain over uniformly bounded and unbounded classes of functions. We show that the results can be generalized also to the bootstrappe dU statistics. The bootstrap approach bypasses the problems faced with the asymptotic behavior due to the unknown parameters of limiting distribution. Furthermore, the bootstrap technique we use in this thesis is the renewal bootstrap, where the bootstrap samplevis formed by resampling the blocks. Since the non-bootstrapped blocks are independent, most proofs reduce to the i.i.d. case. The main difficulties are related to the randomsize of the resampled blocks, which creates a problem with random stopping times. This problem is degraded by replacing the random stopping time with their expectation. Also, since we resample from a random number of blocks, and the bootstrap equicontinuity can be verified by comparing with the initial process, the weak convergence of the bootstrap U-process must be treated very carefully. We successfully derive the results in the case of the k-Harris Markov chain. We extend all the above results to the case where the degreeof U-statistic grows with the sample size n, with the kernel varying in a class of functions. We provide the uniform limit theory for the renewal bootstrap for the infinite-degree U-process with the help of the decoupling technique combined with symmetrization techniques in addition to the chaining inequality. Remaining in the Markovian setting, we extend the weighted bootstrap empirical processes to a high-dimensional estimation. We consider an exchangeably weighted bootstrap of the general function-indexed empirical U-processes. In the second part of this thesis, dependent data are represented by locally stationary random variables. Propelled by the increasing representation of the data by functionalor curves time series and the non-stationary behavior of the latter, we are interested in the conditional U-process of locally stationary functional time series. More precisely, we investigate the weak convergence of the conditional U-processes in the locally stationary functional mixing data framework. We treat the weak convergence in both caseswhen the class of functions is bounded or unbounded, satisfying some moment conditions. Finally, we extend the asymptotic theory of conditional U-process to the locallystationary functional random field {Xs,An : s ∈ Rn} observed at irregular spaced locations in Rn = [0,An]d ∈ Rd, and include both pure increasing domain and mixed increasing domain. We treat the weak convergence in both cases when the class of functions is boundedor unbounded, satisfying some moment conditions. These results are established underfairly general structural conditions on the classes of functions and the underlying models

Streszczenie:

This thesis deals with the problem of the instantaneous frequency (IF) estimation of sinusoidal signals. This topic plays significant role in signal processing and communications. Depending on the type of the signal, two major approaches are considered. For IF estimation of single-tone or digitally-modulated sinusoidal signals (like frequency shift keying signals) the approach of digital phase-locked loops (DPLLs) is considered, and this is Part-I of this thesis. For FM signals the approach of time-frequency analysis is considered, and this is Part-II of the thesis. In part-I we have utilized sinusoidal DPLLs with non-uniform sampling scheme as this type is widely used in communication systems. The digital tanlock loop (DTL) has introduced significant advantages over other existing DPLLs. In the last 10 years many efforts have been made to improve DTL performance. However, this loop and all of its modifications utilizes Hilbert transformer (HT) to produce a signal-independent 90-degree phase-shifted version of the input signal. Hilbert transformer can be realized approximately using a finite impulse response (FIR) digital filter. This realization introduces further complexity in the loop in addition to approximations and frequency limitations on the input signal. We have tried to avoid practical difficulties associated with the conventional tanlock scheme while keeping its advantages. A time-delay is utilized in the tanlock scheme of DTL to produce a signal-dependent phase shift. This gave rise to the time-delay digital tanlock loop (TDTL). Fixed point theorems are used to analyze the behavior of the new loop. As such TDTL combines the two major approaches in DPLLs: the non-linear approach of sinusoidal DPLL based on fixed point analysis, and the linear tanlock approach based on the arctan phase detection. TDTL preserves the main advantages of the DTL despite its reduced structure. An application of TDTL in FSK demodulation is also considered. This idea of replacing HT by a time-delay may be of interest in other signal processing systems. Hence we have analyzed and compared the behaviors of the HT and the time-delay in the presence of additive Gaussian noise. Based on the above analysis, the behavior of the first and second-order TDTLs has been analyzed in additive Gaussian noise. Since DPLLs need time for locking, they are normally not efficient in tracking the continuously changing frequencies of non-stationary signals, i.e. signals with time-varying spectra. Nonstationary signals are of importance in synthetic and real life applications. An example is the frequency-modulated (FM) signals widely used in communication systems. Part-II of this thesis is dedicated for the IF estimation of non-stationary signals. For such signals the classical spectral techniques break down, due to the time-varying nature of their spectra, and more advanced techniques should be utilized. For the purpose of instantaneous frequency estimation of non-stationary signals there are two major approaches: parametric and non-parametric. We chose the non-parametric approach which is based on time-frequency analysis. This approach is computationally less expensive and more effective in dealing with multicomponent signals, which are the main aim of this part of the thesis. A time-frequency distribution (TFD) of a signal is a two-dimensional transformation of the signal to the time-frequency domain. Multicomponent signals can be identified by multiple energy peaks in the time-frequency domain. Many real life and synthetic signals are of multicomponent nature and there is little in the literature concerning IF estimation of such signals. This is why we have concentrated on multicomponent signals in Part-H. An adaptive algorithm for IF estimation using the quadratic time-frequency distributions has been analyzed. A class of time-frequency distributions that are more suitable for this purpose has been proposed. The kernels of this class are time-only or one-dimensional, rather than the time-lag (two-dimensional) kernels. Hence this class has been named as the T -class. If the parameters of these TFDs are properly chosen, they are more efficient than the existing fixed-kernel TFDs in terms of resolution (energy concentration around the IF) and artifacts reduction. The T-distributions has been used in the IF adaptive algorithm and proved to be efficient in tracking rapidly changing frequencies. They also enables direct amplitude estimation for the components of a multicomponent

The octatonic pitch set can be found in the works of many composers since the early nineteenth century, often with different characteristics of the pitch set being exploited by the composers. Much of the literature on octatonicism relates to specific instances in compositions or a specific composer’s approach to it rather than exploring octatonicism from a more holistic perspective. This dissertation serves as a holistic resource for the characteristics of the octatonic pitch set; whether as a scale, especially with regards to common practice harmony; or an unordered set. It does this by considering the contextual historical implications of the octatonic pitch set; the historic lineage of octatonic usage; and, significantly, with the goal of extracting specific compositional devices from the works of various composers that come from a variety of stylistic, historical, and harmonic perspectives. These compositional devices are learnable methods, or conventions that a composer can modify, build upon or implement into their own work. The contextual historical information, along with the description of the characteristics of the octatonic pitch set and, especially, the compositional devices are all intended to be both a single pedagogical resource and starting point for composers in relation to developing new octatonic compositional techniques and a holistic theoretical overview of octatonicism. The evidence, retrieved from third party analysis of select composers’ octatonic works, finds learnable compositional devices from broad stylistic backgrounds that can be reinterpreted and expanded into individualised compositional methods.

TV programs act as an important role in adolescent socialization. Their great influence on adolescents may exceed those of parents or teachers. But neither the types nor the amount of time of local TV programs for teens is sufficient in Taiwan. In order to reduce the cost, many television companies in Taiwan decide to buy foreign programs. This decision hence cuts down on the amount of time of local TV programs, not to mention the often overlooked TV programs for teens. This research author began to participate in the production of My Class in 2014; has clearly observed Taiwanese media’s reduction on TV programs for teens in recent years. My Class presents the common problems faced by adolescents, and simultaneously becomes the speaker of adolescents, arousing their sense of agreement. My Class also encourages adolescents to think from different perspectives when they learn to face their problems. This research aims to understand the meanings and features of the longest Taiwanese TV program for teens, My Class. By literarily reviewing Aristotle’s Poetics, this research uses the six elements of drama to analyze the screenplay of My Class, especially the part related to common problems of adolescence. Moreover, by analyzing the screenplay of My Class, this research aims to understand its production process and beneficial influence. This research also aims to emphasize the value and importance of local TV programs for teens.

This dissertation examines Colombia’s socioeconomic stratification system (SES), an official scheme to classify the country’s housing stock into six strata in order to crosssubsidize utility rates. Established in law in 1994, the SES assigns strata to residential buildings based on their physical characteristics and the amenities available in the surrounding neighborhood. In the popular imagination and among researchers, the SES has come to be understood as more than a system that classifies housing: strata are a part of Colombians’ personal identities, listed on dating profiles and instrumentalized in studies as a demographic category alongside sex and race. This dissertation is guided by two research questions. First, how has the significance of the SES changed such that the system, intended originally to classify dwellings, is now also understood to categorize individuals into distinct social classes? Second, do the categories of the SES function as symbolic boundaries that reinforce patterns of hierarchy and exclusion? To answer these questions, I consider two bodies of evidence. I begin with a comprehensive review of published academic articles that make reference to the SES. Examining a corpus of 52 articles and reports published in English and Spanish, I find that 17 articles misconstrue strata as based on personal characteristics such as income or educational attainment. I argue that the prevalence of this error demonstrates that Colombians have attached meanings and implications to the SES beyond its original intent, and that these reinterpretations are held firmly and uncritically, even by experts. To elucidate how the SES is understood by Colombians of diverse perspectives, I also analyze 31 semistructured interviews conducted with residents of Medellín. The set of interview participants includes residents of housing classified across all six strata, the most comprehensive cross-section of Colombian society yet represented in a project of this type. With evidence from these interviews, I show how narratives that rely on the strata system have interplayed with other conceptual repertoires that Colombians draw on to make sense of socioeconomic class, focusing especially on repertoires rooted in the specific economic history and regional identity of Antioquia. I argue that the strata system has compounded the symbolic boundaries that exist in Colombian society, and that it has been assimilated into racist and classist ideologies. I conclude with an argument for the moral necessity of advancing equity and centering the voices of the oppressed in policymaking and academic research.

The purpose of this work is to investigate the process of employing “Foundations of Democracy Series” for teaching to expectedly cultivate the civic literacy of students in elementary school and improve the problems encountered in a class. Based on the findings of this work, some suggestions were proposed and may benefit future researchers in this field for further studies. This work employed the third-grade students in the class for which the author was responsible as subjects. By taking action research through observations, interviews, perspectives, documentation for recording and analyzing the results, several conclusions can be made: 1.Some of the concepts and ideas are needed to be clarified when lectures about “Foundations of Democracy Series” were given to elementary school students. However, the contents do not conflict with our culture. 2.Applying related teaching strategies is needed to create resonance between “teaching” and “learning” when instructing “Foundations of Democracy Series”. 3.In order to cultivate children with the concepts and true meanings of civic literacy by lectures on “Foundations of Democracy Series”, both parents and teachers need to make efforts on teaching and supervision. Utilizing opportunities for educating children can make them bring the concept into practice. 4.Events and problems in life are closely related, therefore, the four major concepts, responsibility, privacy, justice and authority, are indistinguishably important. Additionally, through the observation of children’s cognition and behaviors, it was learned that teachers should supply information about other related issues for better helping children to cultivate the abilities and accomplishments in participating the civil society in the future. 5.Teaching children the concept of civic literacy using “Foundations of Democracy Series” helps children to solve problems and issues in class. Therefore, it is worth to continue the work. Based on the findings addressed above and the author’s personal opinions, several educational and academic suggestions were proposed. Hopefully, they will be useful and valuable information for workers in the education sector, school administrators, and future researchers.

Streszczenie:

Radio Frequency Power Amplifiers (PA) are essential components of wireless systems and nonlinear in a permanent way. So, high efficiency and linearity at a time are imperative for power amplifiers. However, it is hard to obtain because high efficiency Power Amplifiers are nonlinear and linear Power Amplifiers have poor efficiency. To meet both linearity and efficiency, the linearization techniques such as Digital Predistortion (DPD) has arrested the most attention in industrial and academic sectors due to provide a compromising data between efficiency and linearity. This thesis proposed on digital predistortion techniques to control nonlinear distortion in radio frequency transmitters.

By using predistortion technique, both linearity and efficiency can obtain. In this thesis a new generic Saleh model for use in memoryless nonlinear power amplifier (PA) behavioral modelling is used. The results are obtained by simulations through MATLAB and experiments. We explore the baseband 13.56 MHz Power Amplifier input and output relationships and reveal that they apparent differently when the Power Amplifier shows long-term, short-term or memory less effects. We derive a SIMULINK based static DPD design depend on a memory polynomial. A polynomial improves both the non-linearity and memory effects in the Power Amplifier. As PA characteristics differs from time to time and operating conditions, we developed a model to calculate the effectiveness of DPD. We extended our static DPD design model into an adaptive DPD test bench using Indirect Learning Architecture (ILA) to implement adaptive DPD which composed of DPD subsystem and DPD coefficient calculation. By this technique, the output of PA achieves linear, amplitude and phase distortions are eliminated, and spectral regrowth is prevented.

The advanced linearity performance executed through the strategies and methods evolved on this thesis can allow a higher usage of the capability overall performance of existing and emerging exceptionally performance PAs, and therefore an anticipated to have an effect in future wireless communication systems.

For a oriented genus g surface with one boundary component, S_g, the Torelli group is the group of orientation preserving homeomorphisms of S_g that induce the identity on homology. The Magnus representation of the Torelli group represents the action on F/F'' where F=π_1(S_g) and F'' is the second term of the derived series. I show that the kernel of the Magnus representation, Mag(S_g), is highly non-trivial and has a rich structure as a group. Specifically, I define an infinite filtration of Mag(S_g) by subgroups, called the higher order Magnus subgroups, M_k(S_g). I develop methods for generating nontrivial mapping classes in M_k(S_g) for all k and g≥2. I show that for each k the quotient M_k(S_g)/M_{k+1}(S_g) contains a subgroup isomorphic to a lower central series quotient of free groups E(g-1)_k/E(g-1)_{k+1}. Finally I show that for g≥3 the quotient M_k(S_g)/M_{k+1}(S_g) surjects onto an infinite rank torsion free abelian group. To do this, I define a Johnson-type homomorphism on each higher order Magnus subgroup quotient and show it has a highly non-trivial image.

This thesis is comprised of three problems in number theory. The introduction is Chapter 1. The first problem is to partially generalize the main theorem of Gross, Kohnen and Zagier to higher weight modular forms. In Chapter 2, we present two conjectures which do this and some partial results towards their proofs as well as numerical examples. This work provides a new method to compute coefficients of weight k+1/2 modular forms for k>1 and to compute the square roots of central values of L-functions of weight 2k>2 modular forms. Chapter 3 presents four different interpretations of the main construction in Chapter 2. In particular we prove our conjectures are consistent with those of Beilinson and Bloch. The second problem in this thesis is to find an arithmetic formula for the central value of a certain Hecke L-series in the spirit of Waldspurger's results. This is done in Chapter 4 by using a correspondence between special points in Siegel space and maximal orders in quaternion algebras. The third problem is to find a lower bound for the cardinality of the principal genus group of binary quadratic forms of a fixed discriminant. Chapter 5 is joint work with Jeffrey Stopple and gives two such bounds.

Dissertação de Mestrado em Matemática apresentada à Faculdade de Ciências e Tecnologia da Universidade de Coimbra.
Existem muitos fenómenos que podem ser descritos por séries temporais de valores inteiros não-negativos. Uma modelação adequada destes fenómenos exclui os modelos clássicos, baseados em processos reais, como os modelos ARMA. Há já uma larga classe de modelos de valores inteiros, entre os quais se encontram os modelos INARMA, construídos a partir de uma operação aleatória inteira que substitui a multiplicação escalar usual. Neste trabalho, estudamos dois modelos desta classe, os modelos médias móveis GINMA e INMA(q), principalmente no que diz respeito à caracterização da distribuição limite do máximo. Depois de estabelecida a estacionaridade forte do processo e admitindo que a função de distribuição marginal pertence à classe de Anderson, prova-se que a sucessão de máximos, de amostras com dimensão assintoticamente geométrica, converge em distribuição para uma variável aleatória com distribuição Gumbel discreta.
There are many phenomena that should be described by positive integer-valued time series. To model this type of phenomena, the classical models based on real valued processes, for instance ARMA models, render inadequate. A large class of integer-valued models, including the INARMA models, have been developed with the usual scalar multiplication replaced by an integer-valued random operation. In this work, we study two models in this class, the GINMA and the INMA(q) models, mainly in what concerns the limiting distribution of the maximum. After proving that the underlying process is strict stationarity, assuming that its margins belong to the Anderson’s class we prove that the sequence of maxima converges in distribution to the discrete Gumbel, when a geometric growing dimension of the sample is considered.

This thesis is an in-depth analysis of George Romero's 'Living Dead' tetralogy of films, comprising Night of the Living Dead (1968), Dawn ofthe-Bead (1978), Day of the Dead(\985) and Land of the Dead (2005), examined through the lensf of contemporary film genre theory. The project focuses specifically on issues of the representation of race, class, culture and violence in the four films, and how these representations, along with the concomitant social critique evident in Romero's work, change in response to the upheavals and developments which have occurred in the American social, cultural and political climate over the past four decades. It also focuses on how Romero's films respond to changes in the horror genre, and how Romero both structures his films on the binary oppositions which are central to the genre and deconstructs these oppositions, and the implications that this deconstruction (most notably that of the figure of the zombie, which occupies a zone of constantly shifting liminality between the human and the monstrous) has in relation to Romero's socio-cultural and political commentary implicit in the films.

Relatório de atividade profissional de mestrado em Língua, Literatura e Cultura Inglesas
Num mundo globalizado, caracterizado por uma crescente mobilidade de povos, é amplamente reconhecida a importância que a língua inglesa assume enquanto instrumento de comunicação, investindo-se no seu ensino como um fator essencial para uma aproximação de culturas e de desenvolvimento de uma educação para a cidadania. Assim, tal como preconizado pelo atual quadro legislativo, do qual se destacam as orientações emanadas do Conselho da Europa, para além da aprendizagem de competências exclusivamente linguísticas, torna-se imperativo o desenvolvimento de uma educação intercultural consciente de valores e atitudes cívicas conducentes ao desenvolvimento pessoal e social dos alunos, com vista à criação de uma sociedade mais pacífica e mais justa. Esta dissertação pretende explorar o uso de filmes na aula de inglês de nível secundário como promotores de aprendizagens a vários níveis, incluindo o seu contributo para a consciencialização intercultural e para a cidadania. Assim, partindo de um levantamento de opiniões de professores referentes à dimensão intercultural do ensino do inglês, à cidadania e ao uso de filmes nas suas práticas letivas, foi aferida a importância que os professores atribuem a estas questões e procedeu-se à elaboração de uma lista de filmes com interesse intercultural e para a promoção da cidadania. O uso de filmes na aula de inglês para promover o pensamento crítico, despertar a consciência cívica e intercultural e o respeito pelos direitos humanos, é exemplificado através da sugestão de diversas atividades que tiveram por base o filme Crash (2004).
In a globalized world characterized by an increasing mobility of people, the importance of the English language is widely recognized as a tool for communication. Its teaching essentially brings cultures together and promotes the development of an education for citizenship. Thus, as recommended by the current legislative framework, with special reference to guidelines issued by the Council of Europe, apart from the learning of purely linguistic competences it is imperative to develop an intercultural education aware of civic attitudes and values conducive to the personal and social development of the students, with the view to creating a more peaceful and more just society. This dissertation aims to explore the use of films in the secondary level English class, as the promoter of learning on several levels, including their contribution to intercultural awareness and for citizenship. Thus, starting from a survey of the opinions of teachers concerning the intercultural dimension of the teaching of English, citizenship and the use of films in their school practices, the importance teachers assign to these issues was assessed and a list of films that are of intercultural interest and capable of promoting citizenship was drawn up. The use of films in the English class to promote critical thinking, intercultural and civic awareness and the respect for human rights, is exemplified through the suggestion of various activities which were based on the film Crash (2004).
