Sahtout, Nadia. "L'eau et la ville en climat semi-aride : vers la gestion intégrée de la ressource. Exemple du Grand Sousse en Tunisie littorale." Thesis, Paris 4, 2011. http://www.theses.fr/2011PA040062.
Full textGrand Sousse, oriental part of Sousse governorate, shelters one of the most important regional metropolises of the country, with a concentration on the littoral fringe of the human and economic activities. The demographic explosion and the generalization of the sideboard in drinking water make an important home of water consumption. Now this region is also very marked by the aridity, the main cause of low local resources. Dependent on nearby regions for its water supply, Grand Sousse leads for a long time a running to the harnessing to satisfy growing needs. The traditional political strategy of mobilization and transfers of the resources ending, the future management recommends the extensive appeal to the not conventional resources, some treated waste water and desalinated waters. It is about one of the main control levers of intervention there which Grand Sousse can promote for an "integrated management" of the hydraulic system, besides a management of the demand centred on the savings of water. The thesis mobilized direct inquiries on a representative sample of households, industrial units and hotels; they allowed to draw up balance sheet actions led in the sense of this new orientation, and to understand better the constraints and the met obstacles. The cartographic was a tool indispensable to the representation of this inadequacy between supply and demand in water, the network of supply and distribution, and constituents of the future management of the water. The forward-looking approach allows pulling the air-raid siren at the threat that makes weigh the trend-setting evolution of the demand on the socio-spatial balances, and proposes alternative solutions of this evolution

Full textEarthquakes are the results of rapid slip on active faults loaded in stress by the tectonic plates motion. It is now establish - at least for large earthquakes - that the distribution of this rapid slip along the rupturing faults is heterogeneous. Imaging the complexity of such slip distributions is one the main challenges in seismology because of the potential implications on understanding earthquake genesis and the associated possibility to better anticipate devastating shaking and tsunami. To improve the imaging of such co-seismic slip distributions, three axes may be followed: increase the constraints on the source models by including more observations into the inversions, improve the physical modeling of the forward problem and improve the formalism to solve the inverse problem. In this PhD thesis, we explore these three axes by studying two recent major earthquakes: the Tohoku-Oki (Mw 9.0) and Sumatra-Andaman (Mw 9.1-9.3) earthquakes, which occured in 2011 and 2004 respectively

Full textChile es el país mas largo del mundo con sobre 4300 km de longitud y un ancho promedio de 180 km. Armar una red que abastezca de internet al país naturalmente tiende a unir del extremo norte al extremo sur. Esta tendencia suele comprometer la robustez de la red, haciendo que fallas en esta se propaguen dejando incomunicado al país. En el marco de los proyectos InnovaChile CORFO se propone llevar a cabo el proyecto Estudio y Recomendaciones sobre la Resiliencia de la Infraestructura del Internet Chileno .En este proyecto se realizará un mapa que represente como un grafo la infraestructura de lared a nivel país, para luego hacer estudios acerca de la robustez de ésta. El objetivo es entonces resolver el problema de la creación y mantención de un grafo que represente la red física del internet chileno. Para llevar a cabo el objetivo de la memoria se realiza un análisis del estado previo de la labor de crear y mantener la red, para luego describir casos de uso y definir condiciones para completar el desarrollo. Se hace un estudio de tecnologías para apoyar la creación de la solución y se procede con ella. Se agregan features para creación y modificación del grafo, incluyendo un sistema de historial de acciones para hacer time travel sobre este. Se hace pruebas con datos ficticios para luego usar los datos reales previamente recolectados manualmente. Se valida la solución en términos de cumplirse los casos de uso definidos, usabilidad de la solución y cumplimiento de objetivos específicos. El resultado final es una aplicación web que permite la creación y mantención colaborativa de la red de internet chileno.

Full textLa dynamique des sources impulsionnelles générant des impulsions nanosecondes à microsecondes a été analysée dans la première partie de cette étude. L'influence des réflexions parasites aux faibles taux de répétition (quelques kilohertz) a notamment été mise en évidence. Les effets thermiques dans les lasers Erbium-Ytterbium à forte puissance de pompe ont également été étudiés. Lorsque l'intensité transportée devient suffisamment importante, l'effet non-linéaire
dominant, la Diffusion Brillouin Stimulée (DBS) limite la puissance extractible des amplificateurs.
Nous avons donc développé dans un deuxième temps un modèle original qui rend compte de la dynamique de la DBS dans les amplificateurs dopés. Le caractère guidé des ondes acoustiques qui interviennent a été pris en compte. Un modèle satisfaisant des modes longitudinaux acoustiques a été introduit. Afin d'élever le seuil de la DBS, des fibres amplificatrices faiblement multimodes peuvent être utilisées. Un compromis entre qualité spatiale et puissance crête transportable doit alors être
trouvé. Grâce à nos modèles, nous avons conçu une source impulsionnelle multi-étages qui a permis
d'atteindre 650 µJ pour des impulsions de l'ordre de la microseconde avec une qualité de faisceau caractérisée par un M2~2.

Full textEn av de värsta skogsbränderna i Portugal 2017 var den 17–21 juni och började i centrala Pedrógão Grande och spred sig snabbt till de omgivande områdena Góis, Pampilhosa da Serra och Arganil. Skogsbranden tog 64 liv och stora rökplymer observerades. Rökplymer från skogsbränder är intressanta därför att de bland annat är en källa av växthusgaser till exempel koldioxid (CO2), aerosoler, kolmonoxid (CO) och andra spårgaser som kan påverka luftkvaliteten på lokal och regional skala. Den regionala skalan kan påverkas eftersom rök från skogsbränder kan sprida sig upp till den fria troposfären och den nedre stratosfären med konvektion. Konvektion är när luften blir varm av olika skäl och stiger, luften kyls av när den stiger och blir då tyngre och till slut sjunker luften. Det som kan driva konvektion vid en brand är branden själv och strålning och kan transportera röken från branden långa avstånd, till exempel från Kanada till Tyskland. Den här uppsatsen undersöker hur utsläppshöjden (mellan vilka höjder röken släpps ut från) påverkar transporten av rök och jämför beräkningarna med observationer. Observationer av transport av utsläpp från bränder sker ofta med satelliter och i denna uppsats används data från en återanalys av en samling observationer från MERRA2 (the second modern-era retrospective analysis for research and applications) som observationer. En återanalys är ett dataset som räknas med en modell från i tid och rum oregelbundna observationer från historiska och nutida data. I denna uppsats används den numeriska transportmodellen FLEXPART 10.02 för att beräkna transport av kolmonoxid från skogsbranden i Pedrógão Grande. Höjden av utsläppskällans topphöjd och bottenhöjd i FLEXPART ändrades för att se hur det påverkat rökplymen i simuleringen. Likheten mellan rökplymen från observationerna och simuleringarna beräknades sedan med ett test kallat SSIM och förändringen av SSIM indexet undersöktes. Resultaten var att den bästa simuleringen för de horisontella bilderna med en utsläppshöjd på 100– 300 m, för de vertikala bilderna på 40°N en utsläppshöjd på 0– 1500 m och för de vertikala bilderna på 41°N en utsläppshöjd på 100– 1200 m. Totalt sett (medelvärde från de tre simuleringarna) hade emissions höjden 100- 1200 m den bästa likheten med observationerna. Det finns en osäkerhet i resultaten på grund av tillexempel att det är olika upplösning i MERRA2 och FLEXPART och att väderförhållanden kan ha påverkat beräkningarna. För att förbättra resultatet så kan man göra simuleringar av fler skogsbränder för att se om SSIM indexet uppför sig densamma.

Full textLarge side forces and yawing moments can be generated by the nose asymmetric vortex system separating from a forebody combat aircraft at high angle-of-attack, limiting its flight domain. This study has been conducted to further explore the potential of pneumatic control of forebody vortices as a means of increasing lateral control. Wind-tunnel tests have been conducted on a circular cone model over an angle-of-attack range from 40 to 60 degrees. Continuous and pulsed blowing have been investigated. The optimum effectiveness has been obtained by continuous blowing through two forward-blowing nozzles located near the apex of the model. The ability of this blowing technique to control the vortex asymmetry has also been analysed using computational fluid dynamics. The effects of blowing coefficient, incidence have been studied and compared with experimental data. This analysis provides good understanding of continuous blowing effects on the flowfield

Full textThe idea of crossing the channel has been circulating from 1856 in the leading French and British circles. It has played a part in the relationship between the two countries. The project of a rail tunnel began in 1880 but nevertheless failed, due to rivalries between its promoters, and to the British worries about national defence. New projects did not go beyond paper in the first half of the 20th century. Once Britain had abandoned their official opposition in 1956, investors proposed the shuttle system, which accommodates both rail and road traffic. The projects has acquired a European significance. The work began in 1973 were abandoned by the Wilson government. In 1986 Eurotunnel won a concession with its project of double rail tunnel with shuttles, finalized in October 1987
Vahe, Jonathan. "Une approche multifractale pour la modélisation du micro-mélange à grand nombre de Schmidt." Thesis, Rouen, INSA, 2014. http://www.theses.fr/2014ISAM0023/document.
Full textThis thesis is focused on the simulation of turbulent mixing of passive scalars at high Schmidt numbers (low diffusivity). The modeling work is based on a structural subgrid-scale model for Large Eddy Simulation relying on the multifractal nature of gradient fields in turbulence.The multifractal formalism provides a mean to handle the characteristic intermittency of scalar dissipation fields through a statistical description of their singularities. Direct Numerical Simulations of mixing at several Schmidt numbers above unity are run with a dedicated code. Different methods are used to perform a multifractal analysis of scalar dissipation. The multifractal subgrid-scale model of Burton et al. for velocity is implemented in the Finite Volume code YALES2. A modification of the equivalent multifractal model for scalars is proposed to take into account micro-mixing at high Schmidt numbers. The model shows satisfactory results when tested a priori against direct simulations

Full textBased on a corpus of unpublished oriental hagiographical sources, the present study recounts the history of the most important Sufi order in the 17th and 18th century eastern Turkistan, the Naqshbandiyya äfâqiyya, and in particular his founder saint Âfâq Khwâja (1626-1694). This monograph studies firstly the dynastisation process and the scission of the holy masters (îshân) of the Naqshanbandiyya-Khwâjagan lineage; then it reconstructes the missionary exile of Âfâq Khwâja and his folowers through Lamaist Tibet and Qing China; it analyses the theocratic regime they have founded at their return in 1680 until the Manchu conquest; the thesis ends by an enquiry into the successors of the holy lineage and into attempts to retore Muslim theocracy until the 19th century. We consider the doctrinal aspects of this Sufi power called by us "ishanate" : it consists in a theologico-political utopia, which undertakes to respond to the social concerns

Full textThis research has led to a series of results related to the use of refrigerant blends in heat pump systems. First, after a review of existing methods showing some of their limitations, an in-situ measurement method of mixture circulation composition has been elaborated and can be used for all kind of mixtures. Second, the effect of the circulation composition variation on heat pump system performances and possible capacity control is thoroughly investigated. Third, new mixtures with low GWP and permitting a safe use have been analyzed. Fourth, a steady state heat pump model is elaborated and mixture properties routines (Thermoblend) have been incorporated to simulate heat pump operations with large temperature glide mixtures. Circulation composition and composition effect on the system capacity and performances are analyzed. A new Staged Evaporation and Enhanced Sub-Cooling (SEESC) heat pump system has been designed taking into account the high temperature glide and composition effect. A separation process permits to control the circulation composition. The new system is tested for two different mixtures, and results are compared to classical R-407C heat pump system

Full textWithin the deep-water ocean (depth >1000 m), low frequencies (1-300 Hz) acoustic waves are characterized by very long range propagation. In this context, the propagation is largely impacted by the oceanic environment. Thus, localization methods based on classical plane wave models do not perform well. Matched field processing has been proposed to include better environmental models, but it is known to perform poorly as soon as the environment is not perfectly known. Given that the ocean is a dynamic system, it changes quickly over time and space making this method inapplicable in an operational context. To circumvent this issue, a better way is to consider methods that do not require detailed knowledge about the environment.In this manuscript I consider a quantity called the Waveguide Invariant (WI) which is known to be robust to small environment variations. In particular, I investigate two phenomenons responsible for its dependence to the source-receiver configuration: the dominance of the acoustic field by groups of modes and the frequency dependence of the Eigenmodes. Using a ray-mode approach, these two features are integrated in a WI derivation which provides a thorough way to predict and understand the striation patterns in deep-water context. Then, using this underlying physics driving the propagation along with the concept of mode trapping, a depth localization method is proposed. The input data for the algorithm is a range-frequency intensity, as measured on a horizontal line array. This idea is explored and extended to propose a source depth discrimination which is performed as a binary classification problem

In Brazil there are in operation gamma irradiators with capacity between 0.37 PBq (10kCi) 185 PBq (5 MCi) using radioisotopes 60Co as radiation source. The developed work provides an accurate control anda data acquisition for the application of Good Manufacturing Practices during all fases of an irradiadiation process, required by the standards of ANVISA , ISO and IAEA technical recommendations for the treatment of foods and medical products.. All the steps involved in the irradiation treatment are mapped into process flow (workflow) , where each agent (participant) has its systematized tasks. The data acquisition process, monitoring and control, are based on a set of tools (free software licenses) integrated by a network of efficient communication, including the use of Web resources. Using the Gamma Irradiator Multipurpose IPEN/CNEN/USP all the development was performed to be applied in irradiators facilities operating in industrial scale. The system enables a complete traceability of the process, in real time, for any participant and also the storage of the corresponding records to be audited.

Full textNatrix tessellata represents one specific type of non-toxic snake that have a wide distribution. Particularly this population of dice snake is interesting because it is consists of snakes that inhabit the isolated island Golem grad in Prespa lake in FYR Macedonia.Bearing in mind that this population at this particular site is extremely dense and poorly investigated, the goal of this study was to examine the life history of these species, its morphological characteristics, sexual polymorphism, presence of the different color morphs, duirnal and seasonal activity, predation and their reproductive characteristics. The study was conducted on a total of 3850 individuals of dice snake on the island Golem grad during the spring and summer season in the period from 2008. to 2012., and included the determination of the fitness index and its relationship with a color morph, sex and age categories. Results of this study showed that the population of dice snakes that inhabits the island Golem grad, are specific for several reasons. First, the relatively small area has been inhabited by large number of individuals, with equal representation of all three color morphs (dotted, gray and melanic morph) which represents the specificity and diversity in relation to all other localities inhabited by this species of snake. Also, the average value of measured morphological characteristics in females were significantly higher than in males in all three age categories (juvenile, subadult and adult). Fertility and fecundity, and fitness index have showed the specificity acording to specific zone of the island. By summarizing and analyzing of results it can be conclude that the population of Natrix tessellata which inhabits island Golem grad are very specific due to the uniform presence of all three color morphs that demonstrate their environmental, reproductive and morphological specificity in comparison of dice snakes populations that have been studied in other localities of their distribution range. In order to be fully explained unicity of this population from different evolutionary and ecological aspects, it is necessary to do further research during the next active seasons.

Full textMixed Integer Linear Programming (MILP) is a very popular and useful framework to model industrial optimization problems. This success is due to the facility to model complex optimization problems, the work can be focused on modeling, with a black box generic resolution to optimality with Branch&Bound (B&B) algorithm, or with a specialized decomposition algorithm. If MILP made lots of progresses on the last decades, it is often not sufficient to tackle real world size instances. In such cases, heuristic methods are commonly used to find good quality solutions, without any guarantee to reach the optimum and any proven bound to the optimum. Our work focus on two complex optimization problems from energy management. First application is a discretized daily Unit Commitment Problem of thermal units with specific dynamic constraints. Second application comes from the EURO/ROADEF 2010 challenge, scheduling problem of nuclear power plants' outages for maintenances and refueling. In both cases the methodology was first to model efficiently the considered problem with a MILP compact formulation, and analyze the frontal resolution's limits with B&B. Decomposition methods could also be investigated, before the exact methods are derived in a matheuristic, to be able to tackle real size instances. In particular, Variable Neighborhood Search (VNS) with MILP neighborhoods gave outstanding results on our problems. Our work allowed to estimate the impacts of usual and natural hypothesis. Furthermore, we derived dual bounds for these optimizations problems

Full textKoncept globalnog grada, koji predstavlja osnovni predmet ove disertacije, je vodeća ideja u razumevanju odnosa globalizacije i urbanizacije. Unutar njega, gradovi se posmatraju kao strateška mesta lokalizacije, artikulacije i realizacije (ili čak proizvodnje) globalizacije, odnosno mesta na kojima se kristališu dijalektički odnosi izmeĎu lokalnih i globalnih pojava i procesa. Osnovni cilj disertacije je odgovor na pitanje da li je, i u kojoj formi, koncept globalnog grada adekvatan okvir za razumevanje urbane budućnosti sveta i da li se moţe primeniti kao integrišuća paradigma u urbanoj sociologiji. U radu se izlaţe geneza i evolucija koncepta globalnog grada i njegova kritička evaluacija. Ističe se da je on nezaobilazan za savremenu (urbanu) sociologiju jer omogućava teorijsko i metodološko objedinjavanje opštih (globalnih) i posebnih (lokalnih) dimenzija globalizacije čime se produbljuju mogućnosti za istraţivanja odnosa aktera i strukture. Da bi se ovakav potencijal realizovao, koncept globalnog grada mora da bude redefinisan i to tako da se prevaziĎu njegovi ključni problemi: zapadnocentričnost, prezentizam i ekonomizam.
Zaključujemo i da bi dublja integracija koncepta globalnog grada i urbane sociologije omogućila objedinjavanje jake metodološke osnove za analizu globalnih urbanih procesa sa kritičkom (urbano) sociološkom teorijom, čime se otvaraju mogućnosti za obnovu urbane sociologije i njen povratak u centar savremene kritičke društvene misli i prakse.

Se estudiaron en campo genotipos de cebada sin cubiertas y de grano coloreado que se diferenciaban en una variedad de compuestos bioactivos valiosos y saludables, en diferentes condiciones ambientales y de temperatura. El estrés por alta temperatura durante el llenado del grano aumentó la concentración de compuestos bioactivos claves en el grano. Se debe considerar la cosecha temprana de granos inmaduros para maximizar la capacidad antioxidante. El 30% más externo de las fracciones perladas parecen la mejor opción para explotar la capacidad antioxidante y la alta composición fenólica, mientras que los granos perlados pueden proporcionar harinas enriquecidas con β-glucanos.

La cebada desnuda y de grano morado ofrece nuevas vías para satisfacer la creciente demanda de productos saludables, proporcionando un mayor contenido de fibra dietética y compuestos bioactivos, una mayor capacidad antioxidante y un índice glucémico estimado más bajo que las harinas comerciales refinadas e integrales de trigo.
Although rarely used in food, barley is receiving increasing interest as a healthy grain, due to its nutritional properties. Hull-less and coloured-grain barley genotypes differing in an array of valued and healthy bioactive compounds, were studied in the field under different temperature and environmental conditions. High temperature stress throughout grain filling increased concentration of key bioactive compounds in the grain. Early harvesting of non-mature grain should be considered as a way to maximize antioxidant capacity. The 30% outermost of the pearling fractions seem the best option to exploit antioxidant capacity and high phenolic composition, while pearled grains may provide β-glucan-enriched flours. Husks are also a valuable healthy material, particularly for ruminant feed. Hull-less and purple-grain barley offers new avenues to fulfil the increasing demand for healthy products, providing higher content of dietary fibre and bioactive compounds, greater antioxidant capacity and lower estimated glycemic index than commercial refined and whole wheat flours.

Full textThe object of this thesis is an anlysis of the uses of parkings areas of two social housing neighbourhoods in parisian suburb. His purpose is to show how parking areas, usually considereted as non lieu or conflicted and disordered space, are, on the contrary, according to inhabitants interrogated, real areas of living. Parkings are in-between spaces and their tenure are doubtful. They are private places occupied by the car which is a real propriety people pay attention, and handy man and people who tend to lived them as extension of the flat. This characteristics tend to individualize the building and to reduce the public space of high rise flats estated often accused of beeing too huge. Parkings area are in the same time public because of their localisation outside and their activities : power-loom, tinkering are public activities related to work which is an institution. Parkings allow to study the evolution of public and private spaces and the appropriations of the high rise flats

Full textAn instrument recording of a signal always contains noises in addition to the studied signal. This thesis focus on the study of some noises and some signals at low frequency. Several local effects (such as topography, local geology and cavity effects) have been studied in seismological and gravimetric data at tidal frequencies. These local effects imply a strain-tilt coupling. This study has allowed us to find a minimal set of the various observables (tilts, horizontal and vertical displacements, strains and gravity) necessary to explain seismological data. 4 observables are necessary to reconstruct the observed perturbations. Thus, we obtain a set of 4 coefficients stable in time for each station and each instrument, enabling a systematic reduction of the local effects in data. As frequencies increase, the inertial effect becomes more and more prominent relatively to the local effects. The Sumatra earthquake of December 26, 2004 allows us to observe and to characterize these local effects for the first time in the lowest Earth free oscillations data. Finally, this study has demonstrated that the lowest Earth free oscillations can provide useful information to the source study of very large earthquakes. Singlet phases of the gravest multiplets (such as 0S2, 0S3, 0S4, 1S2, 0S0, or 1S0) can be used to constrain an overall picture of the rupture (the length, the duration and consequently the mean rupture velocity) for large earthquakes with magnitude larger than 8. The phase analysis of the gravest free oscillations has been mainly performed for the Sumatra earthquake of December 26, 2004, which is exceptional by its spatial and temporal extension. For this event, we have found a rupture length of 1250 km, a source duration of 550 s, and a mean rupture velocity of 2. 3 km/s

Full textThe research carried out in the scope of this doctorate degree aims to develop innovative techniques to improve the collection of biological and mineral samples underwater using robotic manipulators. The end goal is to enhance the handling by robotic means in order to maximise sample quality provided to marine scientists. The proposed techniques are based on an in-depth analysis of the robotic arm actuators used in most recent underwater intervention vehicles, in order to improve the accuracy of the positionning of the tools held by the manipulator arms. An instrumented tool has also been developed with the aim to measure the reaction forces and adapt the interaction between the arm's end-effector and its environment to improve samples handling. These methods and the other contributions described in this thesis have been experimentally validated using Ifremer's hybrid-ROV Ariane equipped with two electrically actuated heterogeneous robotic arms

Full textThis thesis investigates domain decomposition methods, commonly classified as either overlapping Schwarz methods or iterative substructuring methods relying on nonoverlapping subdomains. We mainly focus on the mortar finite element method, a nonconforming approach of substructuring method involving weak continuity constraints on the approximation space. We introduce a finiteelement framework for the design and the analysis of the substructuring preconditioners for an efficient solution of the linear system arising from such a discretization method. Particular consideration is given to the construction of the coarse grid preconditioner, specifically the main variantproposed in this work, using a Discontinuous Galerkin interior penalty method as coarse problem. Other domain decomposition methods, such as Schwarz methods and the so-called three-field method are surveyed with the purpose of establishing a generic teaching and research programming environment for a wide range of these methods. We develop an advanced computational framework dedicated to the parallel implementation of numerical methods and preconditioners introduced in this thesis. The efficiency and the scalability of the preconditioners, and the performance of parallel algorithms are illustrated by numerical experiments performed on large scale parallel architectures

Full textIn this dissertation is applied creativity as a new approach to the urban tourism development. It is important to understand and realize that the life of the city depends of its citizens. If the city provides better quality of life to them, the citizens will be more satisfied and inspired by the city and the city will revive. Many cities are losing the battle with the destructive forces, as they assume that the problems are so big and that it is not possible to cope with them, especially if urban planning instruments and finances are not right. However, some urban experiences from the world show a proof that it is not true. It is always possible to something else, something little, maybe hidden, but significant for sustainability of the city. The future demands full dedication with constant innovation. That requires flexibility, risk and disallowance of a need for security that is found in old ways of solving problems and dealing with challenges. There the creativity is needed. Creativity is achieved when we see what can be done for urban sustainability with very few resources. Here lies the key of urban acupuncture, simple, fast methods, which releases energy and causes a large immediate social satisfaction. Some examples from the world show that every city, can improve the quality of life for its citizens, in a few years even the one of more then million inhabitants.

Full textColonization and immigration create areas called “in-between spaces”. Limits betweencultures and identities in these “in-between spaces” are coming under some question.As a result, multiple cultural mixings are generating. As part of our research, wefocused specifically on two districts located in the city of Sousse, in the central-east of Tunisia, known as Gabadgi El Foukani and Gabadgi Loutani, or in Sicilian « Capaci Supra e Capaci Jusu3».These two districts take on Sicilian locality name, Capaci. The most interesting fact is that these places, not only, were built and occupied by mixed populations, mostly Sicilian immigrant, but also there were other communities well diversified in terms of nationalities and beliefs. These districts were then gradually reinvested by an exclusively Tunisian population.The historical and social context of these districts has led us to focus our attention on the relationship between ambiances, urban public space and the notion of cultural mixing. Verification of the hypothesis of persistent specific ambient characteristics is a real scientific challenge for this search. We have chosen the notion of cultural mixing more than another form of mixing since it presents itself as a temporal thought. We were therefore led to question the ambiences of the districts by apprehending the cultural mixing as becoming, as born transformation process of meeting others, and as an internalized experience over time.Our work methodology is deployed in three movements that have crossed and enrichedeach other: Observe & tell, describe, and experiment. The first two phases were moreconcentrated on working on the site. The third phase was presented in the form of anexperiment developed under the aegis of an installation-projection

А special methodological procedure, including redefinition of mixed-use index, has been formulated for exploring the relations between the program structure of the city and a number of other parameters, which enabled making of well-grounded conclusions about contemporary cities, as complex systems. The particular area of study is the city of Novi Sad and five specific neighbourhoods, and on the basis of results of the work, there were given recommendations for improving of research and planning of mixed uses.

Full textIn the first part of this thesis, we have focused on the blind identification of non-binary error correcting codes over the Galois field GF(2m). A study of the properties of Galois fields and non-binarycodes has been presented so as to get the essential elements for a blind identification of non-binary codes parameters. From the knowledge of only the received symbols, methods have been developed to identify the code parameters in the case of a noiseless transmission. The relevance of this approach has been highlighted when the parameters of the used Galois field are known bythe receiver. A theoretical study of rank criterion behaviors has been also presented to justify its use by the most existing identification methods. Then, three blind identification methods of the codeword size for binary and non-binary linear codes have been developped in the framework of a noisy transmission. In order to identify a dual code basis, an existing method for binary codes based on the use of a hard decision demodulation has been generalized to non-binary codes. The detection performance of this technique has been improved when an iterative process based on the joint use of a soft-decision demodulator and a soft-decision iterative decoding is introduced. In the second part of this thesis manuscript, a mathematical formalism is proposed in order to investigate the impact of mapping-demapping functions on linear algebra computations and properties over Galois field in the case of non-binary error correcting codes. Finally, this formalism has been exploited to detect or/and correct some digital transmission problems such as a bad synchronization. Finally, we have studied the impact of some mapping-demapping functions on the blind identification ofnon-binary error correcting codes parameters

Full textIn this thesis, our main objective is to develop efficient unsupervised approaches for large dimensional problems. To do this, we consider Bayesian approaches, which allow us to jointly estimate regularization parameters and the object of interest. In this context, the main difficulty is that the posterior distribution is generally complex. To tackle this problem, we consider variational Bayesian (VB) approximation, which provides a separable approximation of the posterior distribution. Nevertheless, classical VB methods suffer from slow convergence speed. The first contribution of this thesis is to transpose the subspace optimization methods to the functional space involved in VB framework, which allows us to propose a new VB approximation method. We have shown the efficiency of the proposed method by comparisons with the state of the art approaches. Then we consider the application of our new methodology to large dimensional problems in image processing. Moreover, we are interested in piecewise smooth images. As a result, we have considered a Total Variation (TV) prior and a Gaussian location mixture-like hidden variable model. With these two priors, using our VB approximation method, we have developed two fast unsupervised approaches well adapted to piecewise smooth images.In fact, the priors introduced above are correlated which makes the estimation of regularization parameters very complicated: we often have a non-explicit partition function. To sidestep this problem, we have considered working in the wavelet domain. As the wavelet coefficients of natural images are generally sparse, we considered prior distributions of the Gaussian scale mixture family to enforce sparsity. Another contribution is therefore the development of an unsupervised approach for a prior distribution of the GSM family whose density is explicitly known, using the proposed VB approximation method

Full textDuring the last decades, Blind Source Separation (BSS) has become a key analysis tool to study multi-valued data. The objective of this thesis is however to focus on large-scale settings, for which most classical algorithms fail. More specifically, it is subdivided into four sub-problems taking their roots around the large-scale sparse BSS issue: i) introduce a mathematically sound robust sparse BSS algorithm which does not require any relaunch (despite a difficult hyper-parameter choice); ii) introduce a method being able to maintain high quality separations even when a large-number of sources needs to be estimated; iii) make a classical sparse BSS algorithm scalable to large-scale datasets; and iv) an extension to the non-linear sparse BSS problem. The methods we propose are extensively tested on both simulated and realistic experiments to demonstrate their quality. In-depth interpretations of the results are proposed
