Texto completoastrophysiques fait l'objet d'un vif débat depuis maintenant une trentaine
d'années. On
propose ici une étude de ce transport en considérant plusieurs instabilités
pouvant conduire à de la turbulence développée dans les disques. La première
instabilité proposée est l'instabilité hydrodynamique sous critique de
cisaillement. Une étude numérique de cette instabilité nous permet de montrer
que, bien que non détectable dans les simulations, le transport obtenu sera
très probablement bien trop faible pour expliquer les observations actuelles.
Nous étudions ensuite l'instabilité strato-rotationnelle et nous montrons
par un développement analytique que les contraintes sur les conditions aux
limites empêchent la formation de cette instabilité dans un vrai disque. Enfin,
nous nous intéressons à l'instabilité magnéto-rotationnelle en présence d'effets
non idéaux (viscosité et résistivité magnétique). Nous montrons alors que ces
effets non idéaux, bien que faibles a priori, ont un fort impact sur
l'efficacité de la turbulence finalement engendrée. Ce dernier point montre le
rôle que peut avoir la microphysique dans le processus de saturation, et la
nécessité d'avoir une modélisation de ces effets afin d'obtenir un
modèle de transport cohérent dans les disques d'accrétion.

Texto completoAngular momentum transport in accretion disks has been a highly controversial debate for 30 years now. We present here a study of this transport, considering sorne instabilities that can leads to developed turbulence in disks. The first instability considered is the subcritical hydrodynamic instability. Our numerical study shows that, although not directly observed in simulations, this instability should lead to a very weak turbulent transport, and is probably not relevant to explain disks observations. We then concider the stratorotational instability, and we show using an analytical approach that it requires very specifie boundary conditions, which prevent this instability from appearing in disks. Finally, we study the magnetorotational instability, including non ideal MHD effect (resistivity and viscosity). We show numerically that these effects, although small compared to ideal MHD terms, can have a strong impact on the turbulence effieiency. This point emphasize the role of microphysic effects in the saturation process, and the necessity to modelize these phenomena to get a self-consistant accretion disk transport model
Ioannidis, Eleftherios. "Local and remote sources of Arctic air pollution". Electronic Thesis or Diss., Sorbonne université, 2022. https://theses.hal.science/tel-03889862.
Texto completoThe Arctic region is warming faster than any other region on Earth due to the effect of greenhouse gases, notably CO2, and short-lived climate forcers of anthropogenic origin, such as black carbon (BC). Over the last 20-30 years, remote anthropogenic emissions over mid-latitude regions have been decreasing. Anthropogenic emissions within the Arctic are also contributing and might increase in the future and further affect Arctic air pollution and climate. Natural emissions, such as sea-spray aerosols, also might increase due to on-going climate change. However, the processes and sources influencing Arctic aerosols and trace gases are poorly quantified, especially in wintertime. In this thesis, quasi-hemispheric and regional simulations are performed using the Weather Research Forecast model, coupled with chemistry (WRF-Chem). The model is used to investigate atmospheric composition over the wider Arctic and during two field campaigns, one in northern Alaska at Barrow, Utqiagvik in January and February 2014 and the second in Fairbanks, central Alaska in November and December 2019 during the French pre-ALPACA (Alaskan Layered Pollution And Chemical Analysis) campaign. First, modelled inorganic and sea-spray (SSA) aerosols are evaluated at remote Arctic sites during wintertime. Then, the model is improved with respect to SSA treatments, following evaluation against Barrow field campaign data, and their contribution to the total aerosol burden within the Arctic region is quantified. A series of sensitivity runs are performed over northern Alaska, revealing model uncertainties in processes influencing SSA in the Arctic such as the presence of sea-ice and open leads. Second, a sensitivity analysis is performed to investigate processes and sources influencing wintertime BC over the wider Arctic and over northern Alaska, with a focus on removal treatments and regional emissions. Variations in model sensitivity to wet and dry deposition is found across the Arctic and could explain model biases. Over northern Alaska, regional emissions from petroleum extraction are found to make an important contribution to observed BC. Model results are also sensitive to planetary boundary layer parameterisation schemes. Third, the improved version of the model is used to investigate the contribution of regional and local sources on air pollution in the Fairbanks area in winter 2019. Using up-to-date emissions, the model performs better in winter 2019 than in winter 2014, when compared to observations at background sites across Alaska. Underestimations in modelled BC and sulphate aerosols can be partly explained by lacking local and regional anthropogenic emissions. In the case of sulphate, additional secondary aerosol formation mechanisms under dark/cold conditions also need to be considered

Texto completoIn the Big Data era, companies are moving away from traditional data-warehouse solutions whereby expensive and timeconsumingETL (Extract, Transform, Load) processes are used, towards data lakes in order to manage their increasinglygrowing data. Yet the stored knowledge in companies’ databases, even though in the constructed data lakes, can never becomplete and up-to-date, because of the continuous production of data. Local data sources often need to be augmentedand enriched with information coming from external data sources. Unfortunately, the data enrichment process is one of themanual labors undertaken by experts who enrich data by adding information based on their expertise or select relevantdata sources to complete missing information. Such work can be tedious, expensive and time-consuming, making itvery promising for automation. We present in this work an active user-centric data integration approach to automaticallyenrich local data sources, in which the missing information is leveraged on the fly from web sources using data services.Accordingly, our approach enables users to query for information about concepts that are not defined in the data sourceschema. In doing so, we take into consideration a set of user preferences such as the cost threshold and the responsetime necessary to compute the desired answers, while ensuring a good quality of the obtained results

Texto completoLes contraintes à l’intérieur des plaques résultent de l’action de forces de longueurs d’onde différentes, qui se superposent et s’additionnent. En utilisant une nouvelle méthode (Camelbeeck et al. 2013), déterminant les contraintes générées localement (échelle de 10 à 100 km), nous estimons l’importance relative de cette composante locale du champ de contrainte. En comparant ces contraintes locales avec les contraintes déduites des mécanismes au foyer des tremblements de terre en Europe occidentale, nous suggérons que celles-ci semblent jouer un rôle non-négligeable dans l’occurrence de l’activité sismique. C’est le cas dans des régions où les contraintes locales étaient déjà reconnues, mais également dans des régions précédemment identifiées comme dominées par les contraintes à plus grandes longueurs d’onde.
Le champ de contrainte généré localement est constant à l’échelle de temps des catalogues sismiques, ce qui ne permet pas d’expliquer l’occurrence dans le temps des séismes. Il est cependant modifié par les variations des contraintes locales générées par l’activité séismique elle-même, ce qui explique les séquences de répliques des séismes de Roermond (13/04/1992, Mw=5.4) et d’Alsdorf (22/07/2002, Mw= 4.7) dans le graben de la Roer. Nous y suggérons également l’importance de ces variations à une échelle de temps plus longue (millier d’années) à partir des données de paléoséismologie.
Pour mieux comprendre les relations spatio-temporelles des séismes, nous avons également analysé dans quelle mesure l’occurrence de l’activité sismique dans le graben de la Roer est un processus de Poisson, ou si l’activité future est localisée à proximité des séismes du passé, ou située dans des régions dénuées de séismes à ce jour. L’emploi des méthodes linéaires classiques et de méthodes non-linéaires dans cette région mais aussi dans les îles britanniques et dans le sud de la Norvège montrent que les séismes du passé ne peuvent expliquer les taux d’activité sismique actuellement mesurés. Une partie de l’activité sismique correspond ainsi à une activité de background, indépendante de l’occurrence des séismes du passé. La méthode des multifractales permet aussi de caractériser régionalement l’importance, la variété et continuité des processus responsables de l’activité sismique sans pour autant en identifier les causes.
Notre travail nous a permis d’identifier l’importance relative de certaines causes de l’activité sismique, par exemple l’importance des variations locales des contraintes générées par l’activité séismique elle-même, mais n’a pas permis par exemple d’identifier l’origine de l’activité de background, clairement mise en évidence par l’analyse multifractale./

Texto completoThe 1475 sarreguemines accounts book, a 109 page hand-written document, is a balance sheet that the squire sent every year to the duke oflorraine, in this case rene ii. The local events stand out in sharp relief as it was written at the time when the duke of burgundy was attempting to conquer lorraine. The study of the manuscript first gives interesting socio-historical information on the life and organisation of a manor at the end of the 15th century. Through the taxes which the population had to pay, it is possible to have a better understanding of living conditions and to highlight the social hierarchy of the community. The squire's expenses, recorded in the document, show the carrying out of his responsibilities and the local management which he was accountable for to the ducal authorities. The study of the graphic signs of the document and the comparison with middle-high- german and the sarreguemines modem dialect has made it possible to describe the phonological system of the language used at the time and also to notice the transformations and factural evolutions on the diachronic axis. Finally, a systemic approach to the evolution of this language has been considered, first through time - from the period of middle-high german to today - then through the spatial distribution of dialects by comparison with present, neighbouring dialects

Texto completoThis thesis treats information found in the records of the Malta Order in Toulouse. These studies showed the functioning of the seigniorial power in the Toulouse grand priory of the knights of Saint-John, from approximately 1660 to 1792. At that moment, the administrative monarchy tried to tighten its political hold over the communities in France. The author drew lots of maps to highlight 3 ways of analysis. Firstly, the Maltese seigniorial regime was held to be a statistical sample; it showed how the knights collected the seigniorial levies, for example the tithe and land taxes. Secondly, the personnel who exerted the powers of the missing commanders were hired due to their specific skills: priests - jurists - lawyers - barristers - merchants shared the workload and responsibilities given by the Commanderie. Finally, the exertion of local powers caused lots of clashes between the Commanders and their tenants or their neighbouring lords; an analysis of the legal proceedings showed a periodization whose highest point was reached at the end of the 17th century. This fact may cast doubt on the concept of feudal reaction, at the end of the 18th century in France

Source coding is accomplished via the mapping of consecutive source symbols (blocks) into code blocks of fixed or variable length. The fundamental limits in source coding introduces a tradeoff between the rate of compression and the fidelity of the recovery. However, in practical communication systems many issues such as computational complexity, memory capacity, and memory access requirements must be considered. In conventional source coding, in order to retrieve one coordinate of the source sequence, accessing all the encoded coordinates are required. In other words, querying all of the memory cells is necessary. We study a class of codes for which the decoder is local. We introduce locally decodable source coding (LDSC), in which the decoder need not to read the entire encoded coordinates and only a few queries suffice to retrieve a given source coordinate. Both cases of having a constant number of queries and also a scaling number of queries with the source block length are studied. Also, both lossless and lossy source coding are considered. We show that with constant number of queries, the rate of (almost) lossless source coding is one, meaning that no compression is possible. We also show that with logarithmic number of queries in block length, one can achieve Shannon entropy rate. Moreover, we provide achievability bound on the rate of lossy source coding with both constant and scaling number of queries.

Texto completoIn france and other countries, local demography is handicapped by discontinuity of census. The purpose of this research is to estimate post census population at small geographic levels by using variations of some administrative counts. Administrative series are imperfect from many angles. So they can not lead to very accurate results. A way to mesure the extent of remaining uncertainty is to use different series (building permits, tax households and dependants, voters) and methods. This plurality of data and operating hypothesis leads to estimations of total population for the 542 municipalities and the 55 cantons of gironde (france) and for the 91-96 period. These results, despite their imperfections, are, in a large majority of cases, more pertinent than those obtained through a process only based on past trends. More generally, this research shows the necessity to undertake systematic comparisons in local demography. This precaution concern first post census estimations based on administrative series and operating hypothesis. This research shows, however, that the necessity to undertake systematic comparisons in local demography applies also to census data and classic demographic rates

Texto completoThis thesis presents a census of radio sources selected from the NRAO (National Radio Astronomy Observatory) VLA (Very Large Array) Sky Survey (NVSS) and Sydney University Molonglo Sky Survey (SUMSS) catalogues which have also been observed in the first data release of the 6 degree Field Galaxy Survey (6dFGS), a galaxy redshift survey of the local universe. Radio detections were found for 4,506 galaxies in the 6dFGS near-infrared-selected primary sample, a radio detection rate of 16%. A further 1,196 radio sources were observed by 6dF which were missing from the 6dFGS primary sample either because their host galaxies were too blue in colour or they appeared stellar on optical plates. The full sample comprises the largest and most homogeneous set of spectra and redshifts of radio sources in the local universe ever obtained. Results from the study of these objects form an accurate benchmark from which their cosmic evolution may be understood. 6dF spectra of galaxies have been used to determine the physical cause of radio emission from each object as either star formation or an active galactic nucleus powered by a super-massive black hole. These two classes of radio source have been characterised via a determination of the local radio luminosity function at 1.4 GHz; plotting the variation in their space density with luminosity. The star-formation density of the universe at the present epoch has been determined, the value of which which turns out to be in excellent agreement with previously published values. Fractional luminosity functions have also been determined showing that more massive galaxies have higher star-formation rates and are more likely to host a radio-loud AGN. The large-scale structure of star-forming galaxies and radio-loud AGN in the local universe has been studied by determining their clustering properties via the two-point correlation function. Radio-loud AGN are found to cluster more strongly than star-forming galaxies confirming that these objects are biased tracers of the underlying matter distribution. Both star-forming galaxies and AGNs cluster similarly to the underlying host galaxy population in which they reside. This thesis also describes the 843 MHz SUMSS catalogue, made by fitting elliptical Gaussians to sources in images. The catalogue contains radio sources to a limiting peak brightness of 6 mJy/beam at declination less than -50 degrees and 10 mJy/beam at declination greater than -50 degrees. Image artefacts have been classified using a novel technique involving a decision tree, which correctly identifies and rejects spurious sources in over 96% of cases and has ensured the catalogue is more than 95% complete and 90% reliable over most of its flux density range.

Texto completoWaste management is a subject of interest for geographers for two reasons : the unstable space and time aspect and the multiplicity of people concerned at different scales (local, national, european and international) from the production to the treatment. At the beginning of the nineties, the waste management problem appears in France. The situation is urgent : rubbish dumps are numerous, treatment equipments are inadequate or reach saturation, and the public opinion is sensitive to environnemental problems. To clear up this problem, a new policy of recycling programs is planned in 1992 in France. Realized with partners (institution, firm), these thesis study concerns particularly separative collections. This new practice involves all the society (citizens, politicians, industrials). Techniques, behaviour and communication have been investigated on several french sites. Source separation modify people behaviour. Separating wastes, citizen is an active participant of their management. Municipalities are also implicated. This new point of view imposes new agreements with industrials. If users accept source separation idea, municipalities seem confused and industrials are still looking for technics improvements. Waste management is getting more and more complicated. Many interrogations remain

Texto completoIn this study we have investigated the news interview both from the perspective of the journalists and of the subjects of the interview.
We have made interviews with 50 persons who participated as sources in the news and with 21 journalist who wrote the articles in the local newspapers Östran and Barometern in Kalmar, the 21 of November 2008.
The journalists were asked to tell their story of how the articles where produced, how they prepared before the interviews, if they had an image of the articles in advance and if they were satisfied with the outcome of the article. The persons who had been interviewed were asked to tell us how they felt about the interviews, if they were satisfied with the outcome of the article, if they could consider being in the newspaper again and to give their opinion of local journalism.
Most of the persons who had been quoted in the articles said that at least one or two things went wrong in the articles. Despite this they would not hesitate to be interviewed the newspaper again.
Surprising for us was to see how often the journalists get “served” with both the news and the subjects of the interview. It was for an example often that the Journalists visited press conferences and wrote articles from press releases. When the journalists produced news in this way, they simply interviewed those present at the press conference or the contact person in the press release

Texto completoThis doctoral dissertation aims to address three main Research Questions: RQ (1) What are the antecedents that enhance local brand purchase likelihood in emerging markets (EMs), and are there specific factors for food and clothing brands? RQ (2) How can brands present in the market be classified into Global, Local and Glocal based on consumer perceptions, and are the results of these consumer-based categorisations similar to the categorisations based on objective criteria? RQ (3) Is the relationship between previously-identified brand antecedents and brand-purchase likelihood similar for global, local and glocal brands competing in the same category, or different for each type of brand? A gap in the literature has been identified regarding these questions and this research work aims to provide insights into these relationships. The first essay examines the antecedents of the brand purchase likelihood for local brands. The second essay examines how consumer perceptions of brand categorisation differ from the standard categorisations found in the literature, and the third essay examines how these antecedents positively influence the brand purchase likelihood of the different types of brands, and if there is a moderating role in these relationships. The findings of these three essays suggest the following: in study 1 of essay 1, three factors positively influence local food-brand purchase likelihood and also show that, for younger consumers, an additional factor is present. In study 2 of essay 1, five factors are positively related with local clothing-brand purchase likelihood. Essay 2 provides a categorisation of some leading brands sold in the Mexican market into global, local and glocal, based on consumer perspective. The findings suggest that there are relevant differences in the results of this categorisation of brands vs. the traditional objective approaches found in the literature. In essay 3 some antecedents are positively related with brand purchase likelihood, and, in addition, relevant to all brand categories. Our results suggest that the type of brand moderates some of these relationships. All these surveys were conducted among Mexican consumers and data analysed with statistical tests and Structural Equation Modelling (SEM). Our research work contributes to the current academic body of knowledge by highlighting the following areas:1, by combining theories from different streams to develop and test a comprehensive model of drivers of brand purchase likelihood. 2, by developing a typology to measure four types of brands by extending Steenkamp and De Jong’s theory to the branding context. 3, by hypothesising and testing the moderating role of brand type on the effects of these theoretically-grounded drivers of purchase likelihood. All of the above takes place within an emerging-market context. In addition, our research work contributes to the field of management by providing additional insight for brand-managers in emerging markets in the development of sustainable branding and marketing strategies, in order to help them succeed in a globally competitive environment.

Texto completoThe object of this thesis is the extension to complex structures of the RIFF method (Résolution Inverse Fenêtrée Filtrée). Considering a subpart of a structure, the main idea is to build a local Finite Element model using free boundary conditions. First, the general method was developed on beams. Vibration measurements are injected in the Finite Element model of the analysed part of the beam. Rotations are estimated using extra-displacement measurements and elementary shape functions. The method is highly sensitive towards errors present in measurements, so a regularisation had to be used. This one consists in a double inversion of the operator where a Tikhonov regularisation is applied when performing the second inversion. The regularisation parameter is tuned by the L-curve principle. Because of the smoothing effect of the Tikhonov procedure, moments cannot be reconstructed anymore at this stage, but they do still appear as sets of opposite forces. This setback led us to solve the problem by restricting it to forces only equations. At last, the study of the truncature of the domain was conducted in the aim to suppress coupling forces appearing at the limits of the studied area. Then, the case of plates was considered in order to increase progressively the models’ complexities. The Finite Element approach permitted us to implement dynamical condensation as well as Craig-Bampton reduction techniques. This allowed us to reduce the total number of degrees of freedom to be taken into account both from a numerical and an experimental standpoint. For example, dynamical condensation allows to eliminate rotations in the model. Besides, regularisation induces a lack of spatial resolution because of its smoothing effect. A spatial deconvolution technique was therefore developed; it is based on the Richardson-Lucy algorithm which is applied at a post-processing stage. At last, it was successfully proposed to extend the method to the application of detecting defaults present in the structure. The method was also validated on an industrial test bench in order to identify the forces applied by an oil pump taken from a truck’s engine. This phD thesis relied on numerical developments and the method was validated experimentally both in laboratory and industrial context. Main results provide a predictive tool to evaluate injected forces by vibration sources linked to a structure. It necessitates to inject vibratory displacements measurements into a Finite Element model

The purpose of this thesis was to examine what people who had been interviewed and quoted in a local newspaper feel about being interviewed and what they think of the published article. Our aim was also to make a comparison of “known” sources and “unknown” sources.
The main issues were: How do the sources of a local newspaper perceive that they are being treated in the actual interview? What do the sources think of the published article in which they are quoted? Do they trust media and journalists in general? Do the opinions differ between those who are used to being interviewed and those who are unfamiliar with the situation?
This study was carried out through qualitative interviews with respondents who have been quoted in a local newspaper in Jönköping, Jönköpings-Posten. Articles were selected from three days in November. The articles should be based on one or more interviews and had to be large. At least one person should be quoted more than once in the selected article. In total 30 interviews were made.
The study showed that the sources overall were pleased with the article and the way they were being presented. Nor was there anything to complain about when it came to the journalist’s behaviour. But almost everyone expressed certain scepticism when it came to confidence in media in general. However, most of the persons interviewed had an understanding of the ways that journalists work. We were surprised that the result was so positive and also that the people that were not used to being interviewed were more positive than those who often appear in the local press.

Texto completoA microgrid is a promising future network architecture which is coupling the various generators and consumers in a distribution network. This hybrid multi-source system is composed of at least one conventional generation unit and possibly a storage unit and/or a production unit based on renewable energies. Using this structure allows an immediate minimization of the losses by the energy transport, a greater reliability of power delivery and an ability to provide a high power quality energy. In this paper, we study a microgrid based on the use of a micro gas turbine, a photovoltaic array and supercapacitors. All these sources are coupled to the microgrid by power electronic converters and are interconnected to a microgrid central controller. Some local controllers and the microgrid central controller are used for the studied microgrid to achieve its operation optimization. Therefore, the first part of this thesis is devoted to establish a formalism method for a systematic design of local controllers. The second part of this thesis is devoted to the management of all these production and storage units, in order to optimize the microgrid operating. Simulation and testing results validate our design of the microgrid controllers

Texto completoIn the context of still image compression, some new représentation implemented with oriented lifting schemes has been conceived. For this thesis, three implementations of these transforms have been benchmarked upon a criteria considering the minimization of the high frequencies along the local direction of regularity. This orientation is estimated via edge extraction or minimization of a cost function. Both approaches lead to the classification of the directional activity of the image blocks. Those representations of the geometrical features that drive the oriented filtering process are coded in order to be transmitted to the decoder. The coding cost of these representations is compared. Finally an adaptive quantization is proposed to take into account the structural classes and the anisotropy of the representation
