Full textThis work proposes a universal classification of verbs of "thought". It also presents a comparative analytical study of this group of verbs in several languages. The differences between the approaches specific classifications of each language make the task of universal categorization more complex. That's why we're facing in this work to the exploration of all the specifics of these verbs in Arabic and French. We begin this research with an attempt to define what can be a verb of thinking. Then we offer a directory of verbs representing all sub-categories studied. The dictionary and the analysis of the data submitted will be the subject of our second game. The third part, it relies on cognitive-semantic analysis of these verbs. The fourth and final section presents the analysis of these verbs when identified in the aligned bilingual parallel corpus

Full textThe aim of this thesis is to show that it is possible to elaborate a semantic theory which accounts for the semantic structures of verbal predicates. In the first part, we have tried to prove that the semantic description must be led without adopting some constraints such as the principle of syntactic relevance or that of correlation. We have also judged irrelevant the generalization of the structure of a particular semantic class to the other semantic fields. So, we have proposed, in the second part, to establish some homgeneous semantic classes by decomposing the meaning of verbs into atomic elements. But this option is not sufficient in so far as we have to distinguish elements that are required by the meaning of the verb from those which are pertaining to all the clause. This explains why we have introduced, in the third part, the theory of valency in order to distinguish the two notions of "actant" and "circonstant"

Full textThis research concerns the description and explanation of various classifications of Russian verbs, which constitute the largest and most difficult-to-organise part of speech in the Russian language due to the numerous categories and the complicated system of conjugation which have led, over the centuries, to numerous propositions attempting to master this complexity. These attempts differ, according to the dominant ideas of each epoch: in the choice of the objective (Slavonic, Old Russian...), the viewpoint judged pertinent (diachronical, synchronical, logical...), the linguistic criterion adopted (morphological, semantic...) and therefore by the methodologies dependant on these theoretical options, each one revealing new facts (such as the discovery of the aspects), but at the same time becoming an extra complication for a classification and therefore adding more difficulties for acquiring or learning the Russian verb system. Ours is a double objective : to grasp why the existing classifications lead to models that are too complex to be taught as is, and to determine the proper viewpoint from which to remedy the pedagogical problem (which has never been taken into account so far)

Full textThis grammar of Tanimuka, a Tucanoan language of the Colombian Amazonian area, is organized in four parts. The first part, ‘Tanimuka : the language and its speakers’, is divided into three chapters (1 to 3), which establish the sociolinguistic profile of the language and describe the fieldwork conditions. The second part, divided into two chapters (5 and 6), presents a description of the phonology and morphophonology of the language, with a study of the phenomenon of syllabic epenthesis in the verb. The third part (chapters 7 and 8) begins with a general study of the morphosyntactic and syntactic levels, followed by an in-depth study of the noun classification systems: gender and numeral classifier. The fourth part (chapters 9 to 11) focuses on the expression of space, omnipresent in the language. The first chapter presents an inventory of all the elements that express the domain of space in the language. The second provides a detailed analysis of postures and positional verbs in basic locative construction of simple or complex predicates (serial verb constructions). The final chapter is dedicated to the study of the expression of the Trajectory category. The dissertation ends with three annexes, which present, in turn, the visual stimuli created for the investigation of locative verbs of posture and position, a study of the traditional system of numeration and the transcription of a history of oral tradition: 'The tortoise Parekika', glossed and translated

Full textThe starting point of this work is “P” class (“verbes psychologiques”) of Les Verbes françaisof J. Dubois and F. Dubois-Charlier's electronic dictionary. It deals, more precisely, with feeling verbs.Because of the classification's criterions which are not that explicit, our main target is to try tounderstand their syntactic and semantic parameters, then to refine it in order to make small classes,but sharing in common the feeling expressed. Nouns and / or adjectives, morphologically connectedto verbs, and sharing the same syntactic and semantic properties, will be integrated to them. Ouranalysis, based on a large attested Corpus, lead to predicates characterization of “nostalgia”, “regret”,“annoyance” and “astonishment”

Full textThis dissertation attempts to reveal the syntactic bases of a semantic classification of English verbs focusing upon "Verb + Preposition" constructions due to the potential for considering prepositions as efficient interfaces between syntax and semantics. Given the specificity of the English language, the immediate problem was that of distinguishing between prepositions and adverbial particles, both entities being likely to appear after the verb. Syntax given pride of place in this study, a method allowing the isolation of prepositions according to syntactic criteria was developed. Once achieved, the corpus was thus constituted and used to refine the description of the prepositions' syntactic properties. In this, use was made of J. -C. Milner's concepts of positions, sites and places, adapted when necessary in the process. This study revealed several types of "Verb + Preposition" constructions, thus allowing certain additions to F. R. Palmer's study. Types of prepositions were subsequently brought to light and applied to the class of English verbs - starting with the predicative uses of prepositions and what B. Levin called Verbs of Motion. It was thus possible to (i) reveal a correlation between fine syntactic properties of constructions and semantic classes; (ii) reassess B. Levin's verb classes; and (iii) propose a tentative organisation of the English verbal lexicon. The results of this study will, hopefully, encourage further research in the field of "the semantics of syntax" as well as in that of developing its didactic applications

Full textFTLD is a clinical syndrome mainly characterized by progressive deterioration in behavior, personality and/or language resulting from progressive frontal and temporal degeneration. In addition, movement disorder can also be frequently observed. Given this phenotype variability, FTLD clinical diagnosis remains difficult and uneasy to establish with certainty.The final diagnosis relies on neuropathological examination of the brain, the characteristics of these brain lesions and their molecular basis. Indeed, as many neurodegenerative diseases, FTLD are characterized by the presence of protein aggregates in the affected brain regions. However, in contrast to the well-characterized nature of protein inclusions in Alzheimer’s disease (AD), proteinaceous aggregates in FTLD can be composed of different proteins. Thus, approximatively 40% of FTLD cases display aggregates made of abnormally and hyperphosphorylated Tau proteins and constitute the FTLD-Tau subclass. However, most of FTLD brains are negative for Tau inclusions and exhibit neuronal cytoplasmic and/or nuclear inclusions immunoreactive for transactive response DNA binding protein 43 (TDP-43) and constitute the FTLD-TDP subclass). To a lesser extent, another protein called FUS (Fused in Sarcoma protein) is found in aggregates that are Tau and TDP-43 negative. This subclass is thus named FTLD-FUS. Finally, inclusions negative for Tau, TDP-43 or FUS are observed in rare cases of FTLD and associated with ubiquitin-proteasome system related proteins (FTLD-UPS).Gene mutations also play an important role in FTLD with 30 to 50% of patients reporting a positive family history of FTD and 10 to 15% of patients corresponding to dominantly inherited form. Firstly described are the MAPT mutations. Mutations in the progranulin gene GRN were then found to be the most frequent mutations associated with FTLD. More recently, two studies demonstrated that expanded hexanucleotide GGGGCC repeats in a noncoding region of the chromosome 9 open reading frame 72 (C9ORF72) gene was responsible for a large proportion of FTLD. Less frequently mutations in the valosin containing protein (VCP) gene or charged multivesicular body protein 2B (CHMP2B) gene are also found associated with FTLD.Prior to the discovery of the main molecular actors of FTLD, studies described a partial or total loss of soluble or physiological Tau protein expression in both grey and white matter. This loss of Tau was originally found in a subset of dementia called DLDH for Dementia Lacking Distinctive Histopathology (renamed later FTLD-ni for FTLD with no inclusion). In 2006, most of these cases were reclassified as FTLD-U (presenting with ubiquitin positive inclusions). However, additional investigation with specific regards to this loss of Tau expression has not been reported since Zhukareva et al. in 2003. With the progress in genetics and neuropathology of FTLD, the question of whether this reduction of Tau expression is seldom remains ill-defined.This work takes place in this context whose primary goal was to investigate human brain Tau protein expression in Control, AD, FTLD-Tau, FTLD-TDP-GRN, FTLD-TDP-C9ORF72, sporadic FTLD-TDP and sporadic FTLD-FUS brains using western blot analysis. Remarkably, we demonstrated a huge reduction of all six human brain Tau isoforms only in a subset of FTLD-TDP brains with mutation on the GRN gene. Thus, our data clearly suggest that these specific cases, referred to as FTLD-TDP-GRNltau (for low levels of Tau protein), could be part of the current classification as a distinct entity with more severe synaptic dysfunction and astrogliosis. Beside this, we also performed a comparative proteomic study between the different FTLD sub-classes in order to find common physiopathological mechanisms

Full textHyponymy is a sense relation existing between general lexemes (hypernym) and the specific ones (hyponym). For instance, a hypernym parent includes hyponyms like father and mother. The hyponymy relation was regarded by earlier linguists that it could exist only amongst nouns. However, recent studies indicate that hyponymy can also be manifested in other categories such as adjectives, adverbs and verbs. Though there is hyponymy relation existing amongst Kiswahili verbs, various scho¬lars have tended to focus on nominal hyponymy and disregard verbal hyponymy. Therefore, this article has analyzed the hyponymy relation existing amongst selected Kiswahili verbs. In this regard, 24 verbal hypernyms from Kiswahili dictionaries were purposively sampled and their specific hyponyms indicated. Componential Analysis theory by Katz and Fodor has been used in the analysis of these hyponyms. The theory focuses on distinctive features of specific hyponyms that are normally shown by the use of specific signs [+, -]. The data on verbal hyponymy was observed from the Kiswahili dictionaries by the application of symbolic or syntactic approach propounded by Hearst, and Snow et al in order to identify the hypernyms and specific hyponyms in a sentence. These hyponymy relations are analyzed and presented using the set theory style

Full textThis dissertation studies the various uses of the verb-tool kāna in contemporary Arabic. Part I. We start by reviewing how kāna has been described by Arab grammarians and Arabic specialists. We look at both content and form, evaluating the extent to which these descriptions conform to the language they describe. Part II. In order to examine the contemporary Arabic language we chose to use the corpus linguistics methodology. After outlining some theoretical considerations and providing a state of the art in corpus linguistics applied to the Arabic language, we discuss the constitution of our own corpus. This digital corpus includes three types of texts (blogs, literature, press) from seven different countries (Saudi Arabia, Egypt, Lebanon, Morocco, Syria, Tunisia and Yemen). Numbering altogether 1.5 million words, the texts were all published after 2002. Part III. We classify 15,000 instances of kāna and analyze their uses. We quantify the various functions, patterns and expressions through which kāna is deployed, seeking to identify the values conveyed by the verb, especially modal values. We locate this study within an ecology of language by scrutinizing the diatopic and generic settings of the various occurrences

Full textTopical corticosteroids (TCS) are topical anti-inflammatory widely prescribed to treat many skin diseases. Currently, their potency, ranged into four groups, is determined by their vasoconstrictor effect based on an empirical, outdated, subjective and too restrictive test. The aim of this work was to compare specifically the potency of TCS in three situations and to compare it to the current classification:• Anti-inflammatory. A randomized controlled double-blind clinical study was performed on 21 nickel-sensitive patientstreated by four TCS. Different inflammation parameters were objectively assessed with bioengineering tools. The ranking ofTCS potency varied according to time and parameters of the inflammation studied. According to this model, the classificationmay be simplified into three groups.• Antiproliferative. The efficacy of six TCS on immortal keratinocytes proliferation, cell cycle and apoptosis was compared. Theclassification of the antiproliferative potency differed from the current classification.• Antipruritic histamine-mediated. The histamine-release inhibition of eight TCS was compared on skin explants by asubcutaneous microdialysis dosage. The classification of the histamine-release inhibition potency differed from the currentclassification.We have demonstrated that the current classification of TCS potency is not strictly correlated to their anti-inflammatory effect in the context of allergie contact dermatitis, to their antiproliferative effect and to their histamine-release inhibitor effect. Our new approach is to talk about TCS potencies in the plural. A specifie classification adapted to the therapeutic target is needed to be more efficient and reduce side effects
Le, Corre François. "Distinguishing the senses : individuation and classification." Thesis, Paris 6, 2014. http://www.theses.fr/2014PA066419.
Full textThis Dissertation is concerned with two theoretical issues about the senses. The first issue focuses on the question how the senses are to be individuated (regardless of the way one commonly conceive of them). The strategy is to test the ability of the criteria of individuation available in the literature to withstand objections. I argue that the senses are to be individuated in terms of the environmental properties they give access to, and show that this criterion can withstand all of the objections it has received. The second issue is the question why do we believe in exactly five senses? On the basis of observations from anthropology and comparative linguistics, I argue that this belief result from what we been taught. In addition, this Dissertation contains two supplementary studies. The first study focuses on the question how people ordinarily distinguish among the senses. I argue that people are sensitive both to the types of environmental properties the senses give access to and to the body parts they are attached to. The second study is concerned with the phenomenon of sensory substitution that has long been considered as a challenge for the individuation of the senses. I argue that sensory substitution is not a challenge of this kink because the type of environmental information processed by a sensory substitution device is metamodal, i.e. accessible through any sensory modality

Full textVerbs like ‘ausgehen von’, ‘beziehen auf’ or ‘darstellen’ that contain semantically concrete basic verbs (gehen, ziehen, stellen) form an essential part of German general academic vocabulary, i.e. vocabulary that is used across disciplines. Adopting a corpus linguistic approach, the study develops a comprehensive description of these ‚figurative verbs‘. Based on a data-driven methodology it investigates the properties of this lexis and shows that figurative verbs containing typical recurring forms like -stellen, -führen, -gehen and others are highly relevant from a quantitative point of view. On the basis of the most prominently recurring formal parts, a core inventory of verbs is collected and described with respect to the areas of meaning expressed as well as regarding aspects of polysemy. Based on the empirical study, a model for the identification and description of vocabulary is developed, that integrates the hitherto separated quantitative - inventory based and meaning oriented - unit based perspectives. Moreover, it brings together aspects regarding form and function as means of structuring the vocabulary under description. Methodically, the model builds on a combination of the corpus-driven and the corpus-based approach. The model is elaborated as follows: In Chapter 1, important aspects of description that the model should meet are identified based on a survey of existing work on general academic language. Chapter 2 provides a linguistic foundation within the framework of usage-based language description. In particular, it draws on Langacker’s Cognitive Grammar, from which the concepts of linguistic unit and construal are adopted. Chapters 3 and 4 present the corpus linguistic investigations on figurative verbs. In Chapter 5, the empirical results are brought together in a form- as well as function-based typology of figurative verbs. Chapter 6 synthesizes the findings into a model and shows possibilities of application of the proposed approach to other areas of general academic vocabulary. Finally, Chapter 7 summarizes the results from the perspective of language pedagogy and outlines a proposal for the teaching of general academic vocabulary.

Full textSelf-employment scheme have been considerably successful since their introduction. However, its flagship principle of simplification is also its main weakness. While self-employment schemes provide social and fiscal alternatives to unemployment, they can also be easily abused. The reality of self-employment emerges from an assessment of a project’s motivating factors and of its economic implementation. The image of an autonomous entrepreneur with freedom of choices becomes superimposed with the needs of a worker, employing himself and nobody else, employed by himself and not by someone else. After having analyzed the appeals and faults of self-employment scheme, this study proposes more secure self-employment principles by exploring the potential of its inclusion in labour law. An observation of similar mechanisms in neighboring European countries suggests a plausible perspective for the emergence of stronger self-employment right, as long as this does not violate the rights of other economic actors, primarily that of salaried employees.The image of an autonomous entrepreneur with freedom of choices becomes superimposed with the needs of a worker, employing himself and nobody else, employed by himself and not by someone else

Full textImage classification is generally based on two steps namely the extraction of the image signature, followed by the extracted data analysis. Image signature is generally numerical. Many classification models have been proposed in the literature, among which most suitable choice is often guided by the classification performance and the model readability. Decision trees and Galois lattices are two symbolic models known for their readability. In her thesis {Guillas 2007}, Guillas efficiently used Galois lattices for image classification. Strong structural links between decision trees and Galois lattices have been highlighted. Accordingly, we are interested in comparing models in order to design a hybrid model between those two. The hybrid model will combine the advantages (robustness of the lattice, low memory space of the tree and readability of both). For this purpose, we study the links between the two models to highlight their differences. Firstly, the discretization type where decision trees generally use a local discretization while Galois lattices, originally defined for binary data, use a global discretization. From the study of the properties of dichotomic lattice (specific lattice defined after discretization), we propose a local discretization for lattice that allows us to improve its classification performances and reduces its structural complexity. Then, the process of post-pruning implemented in most of the decision trees aims to reduce the complexity of the latter, but also to improve their classification performances. Lattice filtering is solely motivated by a decrease in the structural complexity of the structures (exponential in the size of data in the worst case). By combining these two processes, we propose a simplification of the lattice structure constructed after our local discretization. This simplification leads to a hybrid classification model that takes advantage of both decision trees and Galois lattice. It is as readable as the last two, while being less complex than the lattice but also efficient

Full textHepatocellular adenomas (HCA) are rare benign tumors defined according to the presence of inactivating mutations of HNF1A, activating mutations of the CTNNB1 and IL6/JAK/STAT pathway activation. However, a small number of HCA remain without specific characteristics. We aim to refine the molecular classification of HCA and identify potential associations with the clinical and molecular characteristics of each subgroup of HCA. For this purpose, we collected of 533 HCA of 411 patients. We sequenced the 10 genes known to be mutated in HCA, and we analyzed by quantitative RT-PCR the expression of 20 genes significantly deregulated in the differents moleculars groups of HCA, allowing us to classify HCA according to their genetic and molecular alterations. However, 11% of HCA remained unclassified (U_HCA). In order to identify the genetic and molecular alterations involved in the tumorigenesis of these U_HCA, we analyzed the RNAseq profiles and compared the expression profiles of 4 normal livers and 36 adenomas from differents moleculars groups. A microdeletion of the INHBE gene leading to the formation of a gene fusion between the INHBE gene and exons 2 and 4 of the GLI1 gene, a transcription factor of the Sonic Hedgehog pathway (Hh), has been identified. In addition, the GSEA study, showed an enrichment of the Hh pathway genes in half of the U_HCA analized. We therefore identified a new subgroup of AHC (sh_HCA, 4%), characterized by the activation of the Hh pathway characterized to the presence of an INHBE-GLI1 gene fusion. The comparison of the histological, clinical and molecular characteristics of each of the HCA subgroup allowed us to refine our knowledge of the risk factors, clinical and histological characteristics related to each molecular group. We showed that the new sh_HCA adenoma subgroup was associated with a higher risk of histological and clinical bleeding. A proteomic study of HCA proposed ASS1 as a marker for HCA at high risk of bleeding. Interestingly, a study on hepatic metabolic zonation showed that ASS1 is a marker of the periportal zone of the hepatic lobule. We therefore sought to evaluate the importance of the level of expression of the ASS1 in the molecular classification of HCA and its involvement following the activation of the Hh pathway. In our series of HCA, we showed that the expression of ASS1 belonged to the periportal expression program that was maintained in sh_HCA while in the other subtypes of HCA, it was under-expressed. In addition, in contrast to sh_HCA, we identified the activation of the perivenous program in b_HCA with Wnt/ β-catenin activation. We performed a functional study by transfecting cell lines either by inhibiting the expression of the GLI1 gene. Inhibition by siRNA of GLI1 gene expression in cell lines induces negative regulation of the ASS1 gene. This study shows the importance of the molecular classification of HCA. Indeed, the improvement of this classification allowed the identification of a new subgroup of HCA, the sh_HCA, adenomas presenting a hemorrhagic risk. These findings highlight for the first time the involvement of the Sonic Hedgehog pathway in benign liver tumorigenesis and hepatic zonation in humans. Finally, this new classification could be useful in clinical practice to customize treatement to individual patients based on the molecular characteristics of the tumors

Full textPockets are today at the cornerstones of modem drug discovery projects and at the crossroad of several research fields, from structural biology to mathematical modeling. The goal of my PHD thesis has been to propose a pocket classification based on pocket ligand pairs. This classification could help in the development of pocket-specific virtual screening processes. We have first defined and characterized pockets and in particular druggable pockets. Then we have proposed a five-clusters pocket-ligand pairs classification which reveals five profiles of pockets corresponding to five profiles of ligands. We have seen that one of this profile contains more particularly druggable pockets. This classification have provided a basis to develop a binding partner prediction model, which show promising rates. This method could predict several ligand properties critical for binding to a given pocket, and conversly, several pocket properties for a given ligand

In this aim, the classical methods have provided parameters, rather descriptive than quantitative, which did not give complete satisfaction. This thesis proposes a research of new quantitative parameters based on the principles of fractal geometry. This allows us to establish a classification of handwriting in order to apply to each of the isolated categories the most adapted recognition methods. The fractal behavior of handwriting, which was far from being evident, is first shown. This hypothesis being confirmed, a method for estimation of the fractal dimension is elaborated. A rigorous analysis leads to a distribution of writing into four families according to their legibility. The reliability of these new parameters is tested and the influence of factors external to writing is shown. Finally, the results are compared to those obtained by neuropsychologists who were searching, by other methods, objective solutions to similar problems. Both the value and the interpretation of the parameters stemming from the fractal geometry came to be reinforced. Our obtained results open various perspectives, the lesser not being the signature authentication to which is devoted the last part of the thesis

Full textThe main objective of this thesis is to propose a pipeline for an object recognition algorithm, near to human perception, and at the same time, address the problems of Content Based image retrieval (CBIR) algorithm complexity : query run time and memory allocation. In this context, we propose a filter based on visual attention system to select salient points according to human interests from the interest points extracted by a traditionnal interest points detectors. The test of our approach, using Perreira Da Silva’s system as filter, on VOC 2005 databases, demonstrated that we can maintain approximately the same performance of a object recognition system by selecting only 40% of interest points (extracted by Harris-Laplace and Laplacian), while having an important gain in complexity (40% gain in query-run time and 60% in complexity). Furthermore, we address the problem of high dimensionality of descriptor in object recognition system. We proposed a new hybrid texture descriptor, representing the spatial frequency of some perceptual features extracted by a visual attention system. This descriptor has the advantage of being lower dimension vs. traditional descriptors. Evaluating our descriptor with an object recognition system (interest points detectors are Harris-Laplace & Laplacian) on VOC 2007 databases showed a slightly decrease in the performance (with 5% loss in Average Precision) compared to the original system, based on SIFT descriptor (with 50% complexity gain). In addition, we evaluated our descriptor using a visual attention system as interest point detector, on VOC 2005 databases. The experiment showed a slightly decrease in performance (with 3% loss in performance), meanwhile we reduced drastically the complexity of the system (with 50% gain in run-query time and 70% in complexity)

Full textThe infinitive offers in French many different structures (independent sentence, subordinate circumstantial, relative or infinitive clauses; verbal, adjective or noun phrase – with or without attributes). This mood suggests a simple idea of the process. However the process gets richer, according to the context, with a variety of modal, temporal and other characteristics, concerning the way this process operates or fits into reality. In comparison with Polish, these structures have equivalents that can: 1. Either stay in the infinitive; 2. Or require, instead of the infinitive, one or several forms amongst the following ones: finite form, deverbal noun (or, sometimes, gerund); 3. Or gives the choice between the infinitive and another form. In order to simplify the choice between such and such structure (especially divergent ones), we have conceived a classification of the analysed structures, mostly based on semantic criteria. We have taken into account the place of the infinitive within the argument structure of the verb that precedes and the meaning of this verb (for instance, the idea of manner, expressed with a verb like s’empresser, is very likely to be turned into an adverbial structure, whilst the idea of causality, specific to analytic constructions with the verb faire, tends to be realized in a synthetic way, being due to a single verb). Without offering all the possible translations, our model tries to respect the diversity and the proprieties of the actual linguistic creations

Full textFor political or environmental matters, land cover mapping has become more and more important since the beginning of the XXIst century. This mapping consists in, given a set of land cover classes, classifying ground-level objects according to these classes. Adressing very various applications, from a local scale (city-wise) to a more global scale (world-wide), several projects have been initiated so as to build land cover maps that would fit one of these applications. However, the current means to achieve this mapping are mainly manual, leading to high cost of production both in terms of man power and processing time. The task of building relevant land cover maps lies also in being able to monitor various phenomena in time, but acquiring data can be expansive for frequent updates or computation of maps at large scale. Yet, remote sensors have multiplied for the past two decades and the panel of such sensors is very wide and diverse in a spectral way and in terms of resolution. Among them, optical sensors boarded on Earth observation satellites acquire images in the visible and infrared spectrums, with high revisit time capabilities. SPOT 6 and 7 were launched in 2012 and 2014 respectively, and offer very high resolution images at 1.5m, in four bands. The French Mapping Agency computes each year a full France coverage from the SPOT data available through the THEIA data portal. Although this task has been widely studied in the past by the remote sensing community, by the means of supervised classifiers such as SVMs or random forests, none of the results have yet led to truly automated and satisfying maps that match existing specifications due to mislabelling errors that occur too often. In terms of methodology, the deep learning, and more specifically deep neural networks have proved to be far more efficient than other machine learning algorithms in various fields of research, from computer vision to natural language processing and system recommendation. These days, deep learning has become a part of everyday life, not only for academic research purposes, but also it society where it runs in the background of our smartphones for various tasks. Such ubiquity raises ethical issues: in particular, users’ browsing habits and behaviours are often monitored without them knowing to feed these algorithms. This heavy need for data is what allows deep learning to sketch more accurately a user behaviour, thus leading to more suitable commercial offers based on a history of purchases for instance.In our work, the French Mapping Agency topographic databases represent a real opportunity to massively train deep neural networks on the SPOT monoscopic very high resolution images, so as to produce land cover maps. The works reported in this dissertation are focused on this problematic of land cover mapping with deep neural networks on SPOT 6 and 7 data, with the additional constraint of tackling this task in a more general operational environment (large scale land cover mapping). This latter point ensures that the conducted experiments address occurring questions when classifying large geographic areas. For instance, a specific SPOT coverage is made of one image per territory, which means adjacent areas can have been acquired at different dates, leading to strong appearance discrepancies. Transfer learning is a tool that can help a lot in lots of scenarii so as to reduce both time computation and needs for training samples. Finally, in a context of the automatic update or re-computation of existing topographic database, the use of aerial images in deep neural networks is assessed in several tasks, with an emphasis on the training dataset conception from topographic database that can include some drawbacks

Full textThe study aims to explain the role of external causes in Descartes and Spinoza’s accounts of the mastery of the passions. It consists in three parts: the mind-body union, the passions and their classification, and the mastery of the passions. In the first part I argue that Descartes’ conception of the mind-body union consists in two elements: mind-body interaction and the experience of being one with the body. Spinoza rejects the first element because there cannot be psychophysical laws. He accepts the second element, but goes beyond Descartes, arguing that the mind and body are identical. In the second part I discuss the classifications of the passions in the Passions of the Soul and the Ethics and compare them with the one Spinoza presents in the Short Treatise. Furthermore, I explain that hilaritas is an affect that expresses bodily equilibrium and makes it possible for the mind to be able think in a great many ways. In the last part, I argue that in Descartes the external conditions do not have a significant role in the mastery of the passions. For Spinoza, however, they are necessary. Hilaritas requires a diversity of external causes to occur. Ovid’s Medea has a special importance for Spinoza. An external body may have exceptional qualities whose power surpasses our own power. Medea experiences such a powerful affect when she encounters the famous captain of Argonauts, the handsome and courageous Jason. She loses her equilibrium and cannot follow what her reason tells. The aim of this study is to argue that suitable external causes and bodily equilibrium are necessary for the life according to reason and our individual essence and for our salvation

Full textBackground in music theory Research in the field of organology has seldom been applied to orchestral culture [1]. What significance the budding musical historicism had for an epoch otherwise marked by general enthusiasm toward technology, has been shown in part in studies by Brown [2]. The invention of new orchestral instruments around 1880 and the technical improvements of existing instruments reflect a certain orientation to the past [15 et 17]. Background in linguistics/Romance languages Compositional theories and in turn theories of orchestration, which is the topic at hand, must always translate the object under consideration into another medium; that is, from sound to language [3]. What consequences this transformation has on the perception of sound phenomena with regards to instrumental innovations and in particular a characteristic and specific idiomatic style of writing for an instrument has already been studied on occasion [12 et 16]. Aims By analysing the language in three examples portraying typical everyday practices in the instruction of instrumentation around 1880, insight shall be gained into new currents in orchestration that one truly felt confronted with around that time as a result of the invention of orchestral instruments: Against what did one feel one had to struggle? What threats would be posed by these changes? Which orchestral innovations were desired, accepted, greeted with enthusiasm or condemned? Main contribution At the beginning of the 1880s there was a radical change in European orchestral culture. This change will be reconstructed using the example of the Leipziger Gewandhausorchester by examining the language in three theories of orchestration that were written around 1880: two by authors in Leipzig and, to provide a comparison, one by an author in Genf (Jadassohn, Hofmann, Kling). The idea of the equality of all tones in the chromatic scale, as well as the phantasm of “favourable progress” gave way to a new notion: instead of pursuing endless technical possibilities, one strove for distinct characteristics of each instrument, even accepting limitations to achieve this. Some examples for this development that are described in detail are the thumb valve trombones, the Pfundt timpani, the Kruspe-Schwedler flutes, and the five-string double bass. All the versions mentioned can be traced to innovations made by musicians in the orchestra. Even as late as 1880 the artistic and intellectual atmosphere at the Gewandhaus was one in which members of the orchestra invented or even ‘reinvented’ their own instruments. Near the end of the nineteenth century a growing incapacitation of this type of creative musician may be observed. Moreover there is a new trend: alongside an early form of a performance practice increasingly oriented on historical traditions, the practice of updating a historical sound through the process of retouching developed. Implications Organological research, performance practice, and the theory of orchestration are brought into connection with one another. Knowledge of new instruments and conventions in orchestration around 1880 can have powerful consequences for musical performance insofar as it strives to reproduce a historical sound or in some other way makes a claim to being historically informed. It would radically estrange the sound of this music as we know it, thus making it – in a formalistic sense – possible to hear it in a new way for the first time.
Der einschneidende Wandel der europäischen Orchesterkultur um 1880 wird an konkreten Fällen des Instrumentariums des Leipziger Gewandhausorchesters rekonstruiert. Die Reaktionen auf instrumentale Neuerungen wird nachvollzogen anhand von um die Wende zum 20. Jahrhundert entstandenen Instrumentationslehren (Jadassohn, Hofmann, Kling).
