Les villes sont confrontées à de nombreuses problématiques environnementales. Leurs gestionnaires ont besoin d'outils et d'une bonne connaissance de leur territoire. Un objectif est de mieux comprendre comment s'articulent les trames grise et verte pour les analyser et les représenter. Il s'agit aussi de proposer une méthodologie pour cartographier la structure urbaine à l'échelle des tissus en tenant compte de ces trames. Les bases de données existantes ne cartographient pas la végétation de manière exhaustive. Ainsi la première étape est d'extraire la végétation arborée et herbacée à partir d'images satellites Pléiades par une analyse orientée-objet et une classification par apprentissage actif. Sur la base de ces classifications et de données multi-sources, la cartographie des tissus se base sur une démarche d'extraction de connaissances à partir d'indicateurs issus de l'urbanisme et de l'écologie du paysage. Cette méthodologie est construite sur Strasbourg puis appliquée à Rennes. / Climate change presents cities with significant environmental challenges. Urban planners need decision-making tools and a better knowledge of their territory. One objective is to better understand the link between the grey and the green infrastructures in order to analyse and represent them. The second objective is to propose a methodology to map the urban structure at urban fabric scale taking into account the grey and green infrastructures. In current databases, vegetation is not mapped in an exhaustive way. Therefore the first step is to extract tree and grass vegetation using Pléiades satellite images using an object-based image analysis and an active learning classification. Based on those classifications and multi-sources data, an approach based on knowledge discovery in databases is proposed. It is focused on set of indicators mostly coming from urbanism and landscape ecology. The methodology is built on Strasbourg and applied on Rennes to validate and check its reproducibility.

The study aims to assess performance of Technical Reports as a channel of information for development in the Lesotho context. It concurrently evaluates how a specialized information unit of the Institute of Southern African Studies (lSAS) has performed in its obligation to devise adequate mechanisms for managing the report literature and meeting the development-related needs of users. In order to achieve that aim, the study contextualized development as a process, state, and condition and highlighted some development indicators for Lesotho. Agriculture and gender were selected as sectors of development. Global conferences, as one of the many development strategies that generate technical reports heavily, were used as a benchmark. In the performance and impact assessment methodologies, case study techniques were applied with ISAS as a site and one unit ofanalysis. Technical Reports (TRs) on Lesotho were studied. Triangulation approaches were applied in sourcing data. The academics, information workers, government officials, non-governmental organizations (NGOs) and aid agencies based in Lesotho were surveyed. Research questions that guided the study centred on the productivity, distribution of technical reports, their management by intermediaries, use, non-use and the effects thereon. Seven types ofTechnical Reports feature in the development process, namely Academic, Project, Conference, Survey, Enquiry, Official and Special Committee Reports. Technical Reports are produced at varying levels depending on needs and approaches to development by producers or commissioning bodies. Academic Reports are authored mostly by the academics. The Government, Aid agencies and NGOs produce widely through external consultants/experts, who utilize centres such as ISAS where commissioning bodies do not have information services. TRs productivity is high and diverse in Lesotho, but capacity to manage the output is seemingly low, and hence under-utilization results; ISAS's out-dated mission, lack of, or limited resources and dejure national support in the form of acts and statutes affect the Institute's Technical Reports' services. Production is gender biased, thus making for imbalance in reporting on development. Agriculture as a sector is heavily researched and reported about, but the benefits to the populace are either few or non-existent. Restricted materials are estimated at 30%, but most ofthe TRs are unaccounted for. Hoarding and poor records or information management leave a vacuum that leads to a duplication of previous studies and production. The study confirmed that technical reports are required by all the surveyed groups. Technical Reports are not ofa transient nature even though they reach a peak oftopicality and use at certain periods. Where the channel conveys factual data timeously, there are developmental benefits. Low or non-use is common where there are no specialized information services especially within the civil service. Such negative factors cause delays and infrequent currency, inadequate reporting and erroneous budgetary allocations, for example. Seeminglythere is no clarity on what restricted, secret and limited materials mean. Major recommendations were made. One concerned an integrated approach to managing the channel. This would involve preparing a Manual for the production of Technical Reports which would clarify how to prepare them; for instance, the caliber of personneVexperts who should author reports, the conditions to be observed, the timeliness production, reliability of data used, and centres that would be acknowledged to then qualify for commensurate financial and other support. The other proposes that the envisaged National Research Council be given the powers to enforce the guidelines ofthe manual and related functions. The last recommends assigning to the documentalistsfor classified Technical Reports, the role of managing classified items. Consideration should also be given to important issues raised in the study, being the role of Information, Communication and Technologies (lCTs), sectors of development to be attended to, training and networking in technical report\s. Further studies are also recommended mainly for the causes and effects of the closures of information services that managed technical reports' in southern Africa; longitudinal studies on the impact of non-use oftechnical reports in major sectors ofdevelopment like Agriculture; comparative studies on the impact of specialized centres in the developed and developing countries. Further action is urged under the aegis ofbodies like the Standing Conference ofEastem, Central and Southern African Librarians (SCECSAL), Standing Conference of National and University Librarians. / Thesis (Ph.D.)-University of Natal, Pietermaritzburg, 2002.

Non esistono dati statistici certi sul numero totale di donne nigeriane trafficate annualmente in Italia ed introdotte nel mercato del sesso. Di fronte a questo ampio numero oscuro, bisogna porsi delle domande: cosa succede alla vittima di tratta quando non trova alcuna forma di aiuto o assistenza sociale? Cosa avviene quando non riesce ad uscire dal mercato del sesso? Secondo testimoni diretti e fonti ufficiali, tra le attuali madams vi sono anche ex vittime che hanno fatto carriera nella gerarchia della tratta e dentro le organizzazioni criminali. La mobilità femminile verso il lato gestionale di questo crimine rappresenta la caratteristica più rilevante della tratta di matrice nigeriana: vale a dire, le vittime sono condotte nel corso del tempo a svolgere una parte attiva nel complesso progetto criminale. Questo elemento distintivo al modello nigeriano richiede un’analisi approfondita, tramite nuovi approcci intesi a sottolineare: a) le aree grigie del mercato della tratta; b) i ruoli intermedi che gli individui ricoprono all'interno del modello vittima/reo; c) la mobilità femminile nella gerarchia dei gruppi criminali. Attraverso metodi di stampo antropologico, questo contributo intende effettuare una analisi più approfondita sui molteplici ruoli delle donne nel mercato della tratta umana. / There are not clear figures regarding the group of Nigerian women who are lured annually in the sex market in Italy. Facing such a dark number, several questions on the lives of these unknown women arise: What happens to the trafficking victims who do not find any form of social aid or assistance? What happens when the former trafficked women are not able to exit from the trade industry? According to eyewitness accounts as well as official sources, some current madams were trafficked women in the past. They made a career in the trafficking hierarchy and its organised crime groups. The female mobility towards the organisational side of the trafficking offence represents the most striking characteristic of Nigerian trade industry; that is, the victims are included by their persecutors as active part of a more complex criminal project. Such a distinctive element of Nigerian criminal model needs to be analysed through new approaches aimed at highlighting: a) the grey areas in the trade industry; b) the intermediate roles within the victim/offender model; c) the female vertical mobility in the trafficking hierarchy. Through an ethnographic methodological framework, this study wants to analyse the multiple female roles in the trafficking industry.

Cette recherche porte sur une catégorie spécifique de travailleurs, les Travailleurs Indépendants Economiquement Dépendants (TIED), qui associent une indépendance juridique à une dépendance économique vis-à-vis d’un seul client. En cumulant des caractéristiques typiques des deux catégories classiques que sont les salariés et les travailleurs indépendants, les TIED s’inscrivent dans une zone grise du marché du travail. A partir d’une étude qualitative menée auprès de TIED français et brésiliens du secteur des Technologies de l’Information, nous nous interrogeons sur la signification sociale de cette forme d’emploi hybride et sur la façon dont elle émerge sur des marchés du travail aussi différents que ceux de la France et du Brésil. L’analyse des conditions de travail des enquêtés permet d’abord de situer les TIED sur un continuum entre salariat déguisé et véritable travail indépendant et de distinguer deux profils-types : les prestataires intégrés à la structure commanditaire et les indépendants en transition. Pour étudier les trajectoires professionnelles de ces travailleurs, nous mobilisons ensuite l’approche par les capabilités d’Amartya Sen (2000) : nous montrons que les parcours des TIED – privés des protections du droit du travail par leur indépendance juridique – reposent sur des processus d'accumulation et de conversion de différents types de ressources en libertés réelles (ou capabilités). De plus, si l’approche de Sen permet d’expliquer les différences de capabilités observées au sein de notre échantillon, nous proposons d’enrichir son cadre d’analyse afin de l’adapter à l’étude de trajectoires socioprofessionnelles. Les analyses réalisées nous conduisent enfin à distinguer deux groupes d’enquêtés, les "TIED réticents" et les "TIED épanouis" : les TIED réticents, plus nombreux au Brésil, expriment un attachement fort au salariat, alors que les TIED épanouis voient dans la position de TIED une façon d’échapper à des emplois décevants et trouvent souvent avantage à une situation qui leur offre plus d’autonomie que le salariat et plus de confort que la véritable indépendance. En nous appuyant sur les travaux de Fraser (2010) et Boltanski et Chiapello (2011), nous montrons comment le positionnement des TIED épanouis contribue indirectement à la remise en cause du rôle de l’Etat social.Les TIED apparaissent en définitive comme une figure emblématique d’un processus ambivalent d’individualisation qui contribue à l’émergence d’un sujet en quête d’autonomie, délié de ses appartenances traditionnelles, tout en favorisant une confrontation directe de l’individu avec le marché qui accroît les inégalités. Dès lors, si les désirs d’émancipation et d’autonomie des TIED épanouis nous semblent devoir être pris au sérieux, une réflexion s’impose sur les mesures susceptibles d’étendre les capabilités des individus tout en luttant contre l’exacerbation des inégalités et en préservant un système de mutualisation des risques fondé sur la solidarité. / This research deals with a specific category of workers, the Economically Dependent Self-employed Workers (EDSW), who associate legal independence with an economic dependence upon a single client. Combining typical characteristics of two traditional labor categories, wage-labor and self-employment, EDSW fall within a grey zone of the labor market. Starting from a qualitative survey conducted among French and Brazilian EDSW from the Information Technology sector, we question the social significance of this hybrid employment form and the way it emerges in labor markets as dissimilar as those of France and Brazil. At first, the analysis of EDSW working conditions enables to place them on a continuum between disguised wage-labor and real self-employment and to identify two typical profiles: service providers integrated to the client structure and transitioning self-employed workers. To study their occupational path, we then mobilize Amartya Sen’s capability approach (2000): we show that the careers of EDSW – deprived of labor law protection by their self-employment status – rely on accumulation and conversion processes of various resources types into real freedom (or capabilities). Moreover, if Sen's approach helps explaining the observed differences in capabilities within our sample, we propose to enrich its analytical framework in order to adapt it to socio professional path study. Finally, the conducted analyzes lead us to split our sample into two groups: the ‘reluctant EDSW’ and the ‘fulfilled EDSW’. The reluctant EDSW, more numerous in Brazil, express a strong attachment to wage-labor, whereas the fulfilled EDSW see in EDSW position a way to exit disappointing jobs and often find benefits in a situation which offers them more autonomy than wage-labor and greater comfort than actual self-employment. Mobilizing the theoretical contributions of Fraser (2010) and Boltanski and Chiapello (2011), we demonstrate how the positioning of the fulfilled EDSW contributes to indirectly challenge the welfare state’s role.EDSW ultimately appear as an icon of an ambivalent process of individualization which contributes to the emergence of a subject who is seeking for autonomy, relieved from its traditional affiliations, while simultaneously promoting a direct confrontation of the individuals with the market that increases inequalities. Therefore, if the fulfilled EDSW’s wishes for emancipation and autonomy should be seriously considered, a reflection is needed on measures that may increase individual capabilities while struggling against increasing inequalities and maintaining a system of risks management based on solidarity. / Essa tese está dedicada a uma categoria específica de trabalhadores, os Trabalhadores Autônomos Economicamente Dependentes (TAEDs), que cumulam uma autonomia jurídica com uma situação de dependência econômica em relação a um único cliente. Ao associar características típicas das duas categorias clássicas que são os assalariados e os trabalhadores autônomos, os TAEDs inscrevem-se numa zona cinzenta do mercado de trabalho. A partir de uma pesquisa qualitativa realizada com TAEDs franceses e brasileiros do setor de Tecnologia da Informação, perguntamo-nos acerca do significado social dessa forma híbrida de trabalho e da sua emergência nos mercados de trabalho tão distintos da França e do Brasil. A análise das condições de trabalho dos entrevistados possibilita primeiro situar os TAEDs num continuum entre emprego assalariado e verdadeiro trabalho autônomo e diferenciar dois perfis: os prestadores integrados na estrutura cliente e os autônomos em transição. Para estudar as trajetórias profissionais desses trabalhadores, mobilizamos, em seguida, a abordagem pelas capacidades de Amartya Sen (2000): mostramos que os percursos dos TAEDs – que são privados das proteções trabalhistas pela sua autonomia jurídica – dependem de processos de acumulação e conversão de distintos tipos de recursos em liberdades reais (ou capacidades). Além disso, se a abordagem de Sen permite explicar as diferenças de capacidades observadas na nossa amostra, propomos enriquecer o seu marco de análise para adaptá-lo ao estudo de trajetórias socioprofissionais. As análises realizadas nos levam finalmente a distinguir dois grupos de entrevistados, os “TAEDs reticentes” e os “TAEDs satisfeitos”: os TAEDs reticentes, mais numerosos no Brasil, expressam um forte apego ao emprego assalariado enquanto os TAEDs satisfeitos veem na posição de TAED uma forma de se livrarem de empregos decepcionantes e, na maioria dos casos, creem vantajosa uma situação que oferece uma autonomia maior que o emprego assalariado e um conforto maior que o trabalho verdadeiramente autônomo. A partir das obras de Fraser (2010) e Boltanski e Chiapello (2011), mostramos que o posicionamento dos TAEDs satisfeitos questiona indiretamente o papel do Estado social. Os TAEDs aparecem então como uma figura emblemática de um processo ambivalente de individualização que contribui para a emergência de um sujeito que busca autonomia e está livre de seus pertencimentos tradicionais, ao mesmo tempo em que favorece um confronto direto do indivíduo com o mercado que aumenta as desigualdades. Se achamos que os desejos de emancipação e autonomia dos TAEDs satisfeitos têm que ser levados a serio, é necessário refletir sobre as medidas que poderiam expandir as capacidades dos indivíduos, lutando contra o aumento das desigualdades e preservando um sistema solidário de gestão dos riscos.

The master‘s thesis deals with the influence of the thermal cycle of welding with preheat on castings made of grey cast iron to change the hardness. The thesis deals with the classification of graphitic cast irons, their structure, properties and influences they have on the formation and transformation of the structure. Emphasis is placed on chemical composition and structure stability at elevated temperatures. The practical part deals with the investigation of the effects of casting repair on the decrease of hardness measured in the foundry Heunisch Brno.

The dissertation thesis deals with the relation of a person towards the physical public space from the point of view of an artist/teacher in the academic milieu. The frequently discussed subject of public space is not limited to purely artistic sphere or artistic gesture. It also implies a simple transgression to everyday life related to education and cultivation. An essential part of the research is the case study at the Department of Art Education of the Faculty of Education of the Charles University, which inquires into the perception of the future pedagogues of the physical public space and how they gtranslate it into the art language. The cornerstone stimulus for the research lies in the premise that future teachers will, through the prism of their view of the worl and by their vocation influence the education of the young generation. This fact of transgression is given by the existence of the subject of Art Education where the 3D design itself plays a certain role. The research is focused on what lies behind the phenomena in the process of the creation and inception of "something new" in the physical public space. The concept of a gesture represents a metaphor of material introduction into a space that, at some point, becomes a part o it .The integration is called actualization and the issue of the...

Fault diagnosis can be used to early detect faults in a technical system, which means that workshop service can be planned before a component is fully degraded. Fault diagnosis helps with avoiding downtime, accidents and can be used to reduce emissions for certain applications. Traditionally, however, diagnosis systems have been designed using ad hoc methods and a lot of system knowledge. Model-based diagnosis is a systematic way of designing diagnosis systems that is modular and offers high performance. A model-based diagnosis system can be designed by making use of mathematical models that are otherwise used for simulation and control applications. A downside of model-based diagnosis is the modeling effort needed when no accurate models are available, which can take a large amount of time. This has motivated the use of data-driven diagnosis. Data-driven methods do not require as much system knowledge and modeling effort though they require large amounts of data and data from faults that can be hard to gather. Hybrid fault diagnosis methods combining models and training data can take advantage of both approaches decreasing the amount of time needed for modeling and does not require data from faults. In this thesis work a combined data-driven and model-based fault diagnosis system has been developed and evaluated for the exhaust treatment system in a heavy-duty diesel engine truck. The diagnosis system combines physical insights and neural networks to detect and isolate faults for the exhaust treatment system. This diagnosis system is compared with another system developed during this thesis using only model-based methods. Experiments have been done by using data from a heavy-duty truck from Scania. The results show the effectiveness of both methods in an industrial setting. It is shown how model-based approaches can be used to improve diagnostic performance. The hybrid method is showed to be an efficient way of developing a diagnosis system. Some downsides are highlighted such as the performance of the system developed using data-driven and model-based methods depending on the quality of the training data. Future work regarding the modularity and transferability of the hybrid method can be done for further evaluation.

I efterbörden av Rysslands annektering av Krim 2014 uppstod diskussioner kring rysk krigskonst och hybridkrigföring. Bland tvetydigheterna som uppstod identifieras bland annat vilka strategier som det samtida Ryssland har för att uppnå strategisk överraskning. Denna studie har syftat till att undersöka rysk militär vilseledning i samband med Rysslands strategiska överraskningsanfall på Krim 2014. Studien har genomförts som en teoriprövande fallstudie varvid såväl västerländska som sovjetiska/ryska vilseledningsteorier prövats på det ryska agerande under annekteringen av Krim 2014. Sammantaget visar studiens resultat på förekomster av ryskt agerande i enlighet med samtliga av studiens prövade teorier varvid det i huvudsak var distraktion, dolda aktiva åtgärder samt desinformation som bidrog till den ryska strategiska överraskningen. Studiens oväntade resultat pekar på ett aktivt deltagande av den ryske presidenten personligen varvid det inte går att underskatta betydelsen av en politisk företrädare som Vladimir Putin. Studiens resultat kan vidare tolkas som att den vilseledning som Ryssland genomförde får ses vilande i huvudsak på tidigare dokumenterade sovjetiska teorier. Vidare visar studiens resultat på en hög rysk förmåga till anpassning där tidigare etablerade sovjetiska/ryska teorier kring vilseledning utvecklats till dagens konfliktmiljöer. Studien visar därmed att äldre sovjetiska/ryska teorier på inget sätt är obsoleta utan i allra högsta grad fortsatt är aktuella i dagens globala världsordning. / In the aftermath of Russia's annexation of Crimea 2014, discussions arose about Russian military art of war and hybrid warfare. Questions were identified regarding strategic surprise and what strategies todays’ modern Russia was using. This study aims to investigate Russian military deception in connection with Russia's strategic surprise attack in Crimea 2014. The study was conducted as a single case study in which Western as well as Soviet/Russian theories of military deception was compared with the Russian activities during the Crimea annexation in 2014.  The result shows Russian activities in accordance with both Western and old Soviet/Russian theories of deception. According to the study Russian main focus was distraction, active measures and disinformation leading to the Russian strategic surprise. The study shows unexpected results regarding the amount of personal activity involving the Russian president, Vladimir Putin. The result shows that the significance of a political representative such as Vladimir Putin cannot be underestimated. Additionally the study also shows that the military deception conducted by Russia in and around the period of the Crimea annexation 2014 mainly extracts from previously documented old Soviet theories. It highlights Russia’s ability to adapt into today's conflict environments by bending and adjusting old theories and doctrines. By that meaning old Soviet/Russian theories are in no way obsolete but instead being very much relevant in today's global world order.
