Повний текст джерелаThis thesis concerns the issue of scalp EEG signals pre-processing and it is focused on signal's disturbances caused by non zero reference measurements. These signals perturbations induced by an electrical fluctuation of reference signal can lead to misinterpretation errors in certains analysis. This can be easily seen in inter-signal synchronization measurements such as in coherence studies. Thus, the ideal reference is a null reference. During this research work, we focused on the absolute (zero-reference) potentials estimation from a inverse problem reformulation. Here, two cases are treated, one deals with the case of a reference signal that is sufficiently distant from electrophysiological brain sources so, it is considered as independent signal ; otherwise, it is modeled as a linear combination of sources. Thanks to this modeling, it was shown explicitly that the best estimates of absolute potentials without any a priori information are the average reference potentials. On the other hand, the source-independent reference inverse problem is resolved in a source separation context. For this case, it has been shown that the best estimate of the absolute potentials without any a priori information is equivalent to Minimum Power Distortionless Response/Minimum Variance Distortionless Response (MVDR/MPDR) estimators. On the pretreatment of EEG data, we show on simulated and real signals that measured potentials transformed into average reference improve certain analytical methods used in EEG such as blind source separation (BSS) and localization of brain sources. Beyond the problems of reference, this method can be applied as a constrained source estimation algorithm in order to estimate in a more robust way, particular sources such as artifacts or deterministic exogenous electrical stimulation

Повний текст джерелаAlthough F. Rabbath is more than 80 years old, he goes on traveling all over the world as a soloist and as a teacher. The major contribution of the double-bass pedagogy is the method of the double-bass playing published in the four volumes of the Nouvelle technique de la contrebasse (trad. New Technique of double-bass).His Nouvelle technique de la contrebasse is a new approach to double-bass playing in the pedagogy of this instrument. For F. Rabbath, to get a good quality of music all is important : the sound of the instrument, of the string, of the bow and also the position of the hands, etc.His double-bass was built by Charles Quenoil in 1936. It is the instrument for soloists with « small shoulders », and with a pitch like an orchestral instrument. It seems that this form combines the size of an orchestral instrument sound with the easiness of the playing of a small double-bass.F. Rabbath discovered how the endpins influence the playing. By focusing on the endpins as a balance between the bottom and top of the instrument, he also discovered how the material used for endpins allows more or less vibrations.He and Christian Laborie « took the idea to an elegant solution with a graphite rod installed directly into the end block at the proper angle.1» The new and improved version is called The Rabbath-Laborie Endpin. Gerold Genßler, germany independent production, asked F. Rabbath for help discovered the new string sound. After his production, F. Rabbath play with these strings. In Nouvelle technique de la contrebasse F. Rabbath divided the fingerboard into six positions, defined by the location of natural harmonics on the strings. This is done by using extension fingerings, not extensions with shifts. It is an extension where there is a widening of the hand to reach a new note. F. Rabbath called this technique « pivot ».The player can use for example first, second, third positions without the need for shifts but only by placing the thumb in an appropriate place and just rocking the hand back and forth. Thus, the pivot method enables the succession of several different positions. The « Crab Technique », is another technique discovered by Francois Rabbath. The hand movement resembles a crab's sideways walking : allows for part of the hand to move while the other part remains and vice versa - in this way the hand can move up and down the strings in certain passages without ever fully shifting. F. Rabbath has also developed a number of bowing variations, from whole notes to even faster, middle, tip, and then middle parts of the bow.F. Rabbath works on the theory contributes to the development of the teaching methodology of the double-bass. Over the years has been, still is, teaching the importance of the movement and the position of the body, more than musical. For him, this is the base towards good interpretation of any level of music.In his method François Rabbath also develops his art of being an artist and the desire to share and pass his passion for the double-bass

Повний текст джерелаIn this work we study the gain offered by massively parallel architecture for low-level vision processing. Reviewing the recent evolutions of computer architectures, we underline the massively parallel solutions which are now available to every programmer, the GPU. Exploiting the computing power of these solutions requires a change in programming methodology. However, as far as low-level vision is concerned, we show that most problems can be solved using a restricted number of programming patterns. Finally, we propose a new model to evaluate the complexity of solutions developed on GPUs. Then we apply these programming principles to various low-level vision problems. The first one is optical flow (OF) estimation, which is at the core of many video processing problems. We present an OF estimation on GPU, called FOLKI, which allows good estimation quality on various real-world video sequences with unprecedented computing performance. An application of this work concerns particle image velocimetry, a measurement technique of paramount importance for experimental fluid mechanics. Then we turn toward super-resolution (SR). We first introduce an original and very fast solution, which uses the FOLKI optical flow estimate for image registration. Then various solutions of increasing computational complexity are proposed, which lead to better resolution and robustness. Using these techniques we show very original SR results on video with complex motions (walking person, moving vehicle). Finally the last chapter shows on-going work on 3D measurement contexts in experimental physics and robotics

Повний текст джерелаAs plataformas paralelas e distribuídas de computação de alto desempenho disponíveis hoje se tornaram mais e mais heterogêneas (CPUs, GPUs, FPGAs, etc). As Unidades de processamento gráfico são co-processadores especializados para acelerar operações vetoriais em paralelo. As GPUs têm um alto grau de paralelismo e conseguem executar milhares ou milhões de threads concorrentemente e ocultar a latência do escalonador. Elas têm uma profunda hierarquia de memória de diferentes tipos e também uma profunda configuração da memória hierárquica. A predição de desempenho de aplicações executadas nesses dispositivos é um grande desafio e é essencial para o uso eficiente dos recursos computacionais de máquinas com esses co-processadores. Existem diferentes abordagens para fazer essa predição, como técnicas de modelagem analítica e aprendizado de máquina. Nesta tese, nós apresentamos uma análise e caracterização do desempenho de aplicações executadas em Unidades de Processamento Gráfico de propósito geral. Nós propomos um modelo simples e intuitivo fundamentado no modelo BSP para predizer a execução de funções kernels de CUDA sobre diferentes GPUs. O modelo está baseado no número de computações e acessos à memória da GPU, com informação adicional do uso das memórias cachês obtidas do processo de profiling. Nós também comparamos três diferentes enfoques de aprendizado de máquina (ML): Regressão Linear, Máquinas de Vetores de Suporte e Florestas Aleatórias com o nosso modelo analítico proposto. Esta comparação é feita em dois diferentes contextos, primeiro, dados de entrada ou features para as técnicas de aprendizado de máquinas eram as mesmas que no modelo analítico, e, segundo, usando um processo de extração de features, usando análise de correlação e clustering hierarquizado. Nós mostramos que aplicações executadas em GPUs que escalam regularmente podem ser preditas com modelos analíticos simples e um parâmetro de ajuste. Esse parâmetro pode ser usado para predizer essas aplicações em outras GPUs. Nós também demonstramos que abordagens de ML proveem predições aceitáveis para diferentes casos e essas abordagens não exigem um conhecimento detalhado do código da aplicação, características de hardware ou modelagens explícita. Consequentemente, sempre e quando um banco de dados com informação de \\textit esteja disponível ou possa ser gerado, técnicas de ML podem ser úteis para aplicar uma predição automatizada de desempenho para escalonadores de aplicações em arquiteturas heterogêneas contendo GPUs.

Повний текст джерелаFor a long time I have been thinking that the sound of a bowed tone is cool. There are recordings of music with jazz bowing, but it is not very common and I wondered why. Is it because there are too many difficulties with bowplaying? Or are there a lot of opportunities that only a few bass players take advantage of? The aim of my thesis is to figure out what the difficulties and the opportunities with bow playing on the double bass are in jazz music. In my research process I have chosen a couple of songs, rehearsed and recorded them with a band including drums, guitar, tenor saxophone and viola. After each recording session, I sended the recordings to a couple of active bow playing bass musicians, which answered with comments and advices. Based on the advices and my own analysis of the songs, I did exercises that taught me how to handle the difficulties and how to fully use the opportunities with bow playing in jazz music. In the beginning of the project I had some thoughts about what the opportunities and difficulties would be. Some of the thoughts came out to be, in some cases incorrect, in some cases partly correct and in some cases fully correct. An example is that, beginning my research I thought that playing rhythms with a bow would be difficult, but as it turned out, playing rhythms could also be an opportunity. I then could use more versatile rhythms than with my finger, since the bow allows me to hold a tone for a longer time.

Повний текст джерелаThe main objective of this thesis is to provide radio--oncology specialists with automatic tools for delineating organs at risk of a patient undergoing a radiotherapy treatment of prostate tumors. In order to achieve this goal, we work with CT Scan images. The images are first put in a common frame of reference by means of locally--affine registration based on the pelvic bone structures. A progressive approach consisting of three stages is then applied: the bladder is first delineated, the prostate is later included, and the rectum segmentation is finally integrated. Given the highly heterogenous nature of the images in our database, our contribution for the segmentation process is centered on emph{flexibility}. The bladder is a highly variable structure, both in terms of shape (fillings, compression by surrounding organs) and of intensity levels, the latter due to inhomogeneities caused by the presence or absence (to various levels) of a contrast agent. We propose a segmentation approach that is able to automatically adapt both to the shape and, most remarkably, to the intensity variability. The prostate shows no distinct "edge" in the image itself; its interface with the bladder is often very difficult (if not impossible) to discern, even for the trained eye of medical experts. We have incorporated anatomical information and taken the intensity similarities into account in our approach to contour this structure. An original non--overlapping constraint optimizes the result in terms of image and shape prior information, in order to avoid ambiguities in the delineation of the common boundaries. Finally, the rectum is incorporated in the segmentation. Different acquisition protocols for the CT scans result in images containing rectums with very different characteristics in terms of shape and intensity (due to filling level and nature, air insufflation, contrast agent, etc. ). A flexible method that makes no assumptions about the interior of the structure has been developped and thoroughly tested. The developments that resulted from this thesis have been incorporated to the Isogray software by DOSIsoft, allowing further validation in clinical conditions

Повний текст джерелаClonal lines are a powerful scientific tool for improved genetic characterization of organisms used in research. Inbred fish lines can be produced in only two generations using uniparental reproduction techniques. Androgenesis, achieved with variable success in several freshwater species, has been attempted in the European sea bass (Dicentrarchus labrax L), a marine fish of commercial and scientific interest. The low yields of progenies inheriting only the paternal genome after UV-irradiation of eggs led to considerations on the occurrence of UV screening compounds in pelagic eggs. Mycosporine-like amino acids and gadusol were found in many marine and freshwater organisms, but their occurrence in fish eggs was not clearly related to a behavioral pattern and while gadusol appeared in higher proportions in pelagic marine eggs compared to benthic species, this statement did not apply in freshwater, and moreover the kind of compounds was related to phylogeny. Further studies on DNA photorepair could enlighten hypotheses to understand the mechanisms underlying the disparate results obtained in inducing androgenesis in different fish species. Gynogenesis was reported successful to produce clonal founders in the sea bass, but high numbers of meiotic individuals contaminating fully homozygous progenies highlighted the need for efficient DNA markers to distinguish mitotic gynogenetic individuals. Furthermore, gonad development was highly delayed in gynogenetic progenies enhancing the difficulties to produce clonal lines. A high variability between individuals in the success of uniparental reproduction brought out gamete characterization and quality as a prerequisite

ENGLISH ABSTRACT: Grape and wine phenols consist of flavanols which is the building blocks for tannins. These building blocks are called monomers which consist of catechins, epicatechins, epigallocatechins and epicatechin-gallate. Tannin is important in wine as it contributes to bitterness, mouth feel (astringency) and maturation potential of the wine. Futhermore it has a health benefit as an antioxidant. Anthocyanins are responsible for the colour of red wine. The anthocyanins combine with tannins to form stable polymeric pigments. Due to the importance of tannins and anthocyanins in wine, it is imperitative that different winemaking techniques are used to extract as much of these components as possible and that the analysis is done quickly and accurately. The aim of this study was to evaluate different winemaking techniques and their extraction of tannins and anthocyanins into the wine. Too much tannin extraction can have a negative effect on the sensory quality of the wine. Therefore a second aim was to evaluate the mouth feel properties of a Shiraz wine. A third aim was to compare the two tannin precipitation methods in terms of time efficiency, repeatability and the ease of practice. To investigate the amount of tannin concentration extracted by different winemaking techniques, two cultivars (Cabernet Sauvignon and Shiraz) were used. These treatments included the addition of an enzyme during fermentation [E], cold maceration [CM], post maceration [PM] and the combination of cold and post maceration [CM+PM]. The grapes were harvested in two different climatic areas during the 2008 and 2009 vintages. The two climatic areas were classified according to the Winkler scale as a III (Morgenster) and a IV (Plaisir de Merle). The grapes were harvested at two different ripeness levels in order to evaluate the effect of the different winemaking processes on the extraction of tannins and anthocyanins. One harvest was before (LB) and the other after (HB) the commercial harvest. The results of this study showed significant differences in the phenolic composition of the wines. It was found that the warmer area showed higher tannin concentrations than the cooler area for both cultivars. In the 2008 Cabernet Sauvignon the CM extracted higher concentrations of tannin from the cooler area at both ripeness levels. In the warmer area, CM extracted the highest tannin concentration HB, but the CM+PM extracted the highest tannin concentration from Cabernet Sauvignon at the LB and CM at the HB of the warmer area. In 2009 the PM extracted the highest concentration of tannin at the lower ripeness level, while the E treatment extracted the highest concentration from the warmer area. In the cooler area the CM+PM extracted the highest concentration of tannin at a lower ripeness level, while there were no siginicant differences between the different treatments at the higher ripeness level. The highest anthocyanin concentration was found in the cooler area. The CM treatment was found to have no effect on anthocyanin extraction. Different methods are available to quantify the tannin concentration in wine. Two of the most popular tannin analytical methods are the bovine serum albumin (BSA) and the methyl cellulose precipitable tannin (MCP) methods. The BSA method is a very complex method which uses at least 3 times more reagents than the MCP method. The MCP method only analyzes tannins, while the BSA method analyzes tannins, monomeric pigments (MP), small polymeric pigments (SPP) and large polymeric pigments (LPP). In this study a good correlation was found between the two tannin precipitation methods (R2 – 0.88). There is controversy regarding the variability of these methods. Some scientists found that the two methods show a good correlation with HPLC, while others found that there was no such correlation between the precipitation methods and the HPLC. The MCP method had a practical advantage as it could be performed in half the time required for the BSA method. This has a significant impact in scenarios where a high sample throughput is required although it only measures total tannin. The phenolic composition and mouth feel of the wine was strongly influenced by the climatic area. In the warmer area the effect of tannin concentration on mouth feel was much less than in the cooler area. The wine made of riper grapes, was more grippy, bitter and numbing than the wines made from greener grapes. The E treatment was especially associated with a dry, grippy sensation.
AFRIKAANSE OPSOMMING: Druif en wyn fenole bestaan uit flavanole wat weer die boublokke is van tanniene. Hierdie boublokke, wat bekend staan as monomere, betsaan uit katesjiene, epikatesjiene, epigallokatesjiene an epikatesjien-gallaat. Tanniene is belangrik in wyn aangesien dit bydra tot bitterheid, mondgevoel (vrankheid) asook die verouderingspotensiaal van wyn. As antioksidante hou dit ook gesondheidsvoordele in. Antosianiene dra by tot die kleur van rooiwyn. Antosianiene kombineer met tanniene om meer stabiele polimeriese pigmente te vorm. As gevolg van die belangrikheid van tanniene en antosianiene is dit van uiterse belang dat verskillende wynmaak tegnieke gebruik word om ekstraksie in die wyn te bevoordeel en dat die analitiese metode so vinnig en akkuraat as moontlik gedoen word. Die eerste doel van hierdie studie was om die ekstraksie van tanniene en antosianiene deur middel van verskillende wynmaak tegnieke te evalueer. Te veel tanniene in die wyn kan negatiewe sensoriese kwaliteit tot gevolg het. Daarom is die tweede doel om die sensoriese kwaliteit van Shiraz wyn te evalueer. Die derde doel van hierdie studie was die twee tannien presipitasie metodes met mekaar te vergelyk in terme van die moeilikheidsgraad van die metode, tyd doeltreffendheid en herhaalbaarheid. Verskillende wynmaak tegnieke (ensiem byvoegings [E], koue maserasie [CM], verlengde dopkontak [PM] en ‘n kombinasie van koue maserasie en verlengde dopkontak [CM+PM]) is vergelyk ten opsigte van tannien en antiosianien ekstraksie. In 2008 en 2009 is twee kultivars (Cabernet Sauvignon en Shiraz) in twee verskillende klimatologiese areas gepars. Hierdie areas is geklassifiseer in die Winklerskaal as ‘n IV (Plaisir de Merle) en ‘n III (Morgenster). Om die effek van die verskillende wynmaak tegnieke op die ekstraksie van antosianiene en tanniene te vergelyk, is hierdie twee kultivars by twee verskillende rypheidsgrade geoes. Die eerste oes was net voor kommersiële oes (LB) en die tweede oes het net na kommersiële oes (HB) plaasgevind. Die 2009 Shiraz wyn is organolepties beoordeel om die effek van die verskillende wynmaak tegnieke op die wyn se mondgevoel te vergelyk. Die resultate van hierdie studie toon beduidende verskille in die fenoliese samestelling van die wyne. Dit is gevind dat die warmer area hoër tannien konsentrasies het as die koeler area. In 2008 het die CM+PM die meeste tanniene uit die Cabernet Sauvignon geëkstraheer by LB en die CM by HB in die warmer area. Die CM het in die koeler area meer tanniene geëkstraheer by beide die LB en HB rypheidsgrade. In 2009 het PM die meeste tanniene geëkstraheer by LB terwyl E die meeste tanniene geëkstraheer in die warmer area. In die koeler area het CM+PM die meeste tanniene geëkstraheer, terwyl geen van die behandelings ‘n effek gehad het by HB. Die meeste antosianien konsentrasie was in die koeler area gevind as in die warmer area. In beide 2008 (LB en HB) en 2009 (LB) het CM die meeste antosianiene geëkstraheer, terwyl geen behandeling ‘n effek gehad het by HB. Twee van die mees populêre tannien analitiese metodes is die BSA (bovine serum albumien) en die MCP (metielsellulose presipitasie) metodes. Die BSA metode is ‘n baie meer ingewikkelde metode waarvoor drie keer meer reagense gebruik word as vir die MCP metode. Maar waar die MCP net tanniene ontleed, ontleed die BSA metode tanniene, monomere (MP), klein polimeriese pigmente (SPP) en groot polimeriese pigmente (LPP). Dit help indien daar gekyk wil word na die evolusie van polimeriese pigmente. In hierdie studie is bevind dat daar ‘n redelike korrelasie (R2 – 0.88) tussen die BSA en MCP metode bestaan. Die herhaalbaarheid van die metodes het redelike kontroversie veroorsaak, waar sommige navorsers bevind het dat die BSA metode nie so herhaalbaar is soos eers bevind is nie. Die MCP metode het ’n praktiese voordeel aangesien dit in die helfde van die tyd van die BSA metode uitgevoer kan word. Dit het ‘n groot impak indien ‘n groot hoeveelheid monsters ontleed moet word. Die fenoliese samestelling en mondgevoel word sterk beïnvloed deur die klimatologiese area. In die warmer area was die effek van tannien konsentrasie op mondgevoel kleiner as in die koeler area. Die wyn van ryper druiwe het meer harder, verdowingseffek en bitter nasmaak gehad as by die wyn van groener druiwe. Die ensiem behandeling was meer geassossieerd met droë mond gevoel.

In this work we investigate the effect of a BCS-type pairing term for free spinless fermions, with a propensity to form a condensate of pairs in a 1+1 dimension. Using the of bosonization technique we explore the possible condition of existence of quasiparticles in a superconducting state. Although there is no spontaneous breaking of chiral symmetry the propagator of one-particle fermion is massive and, in fact, resembles the one-particle Green s function of conventional quasiparticles

Повний текст джерелаThe incidence of arboviruses infections has increased dramatically in recent decades in tropical and sub-tropical areas worldwide. Dengue and chikungunya viruses are typically transmitted by mosquitoes and can cause a wide range of symptoms, and sometimes death. Although conventional diagnostic tests can provide diagnosis of acute infections, access to these tests is often limited in developing countries. Early and prompt diagnosis is crucial to improve patient management. Consequently, there is an urgent need to develop affordable, simple, rapid, and robust tools that can be used at ‘Point of Care’ settings.We developed and evaluated a PAD for the detection of the dengue Non Structural 1 (NS1) viral protein in blood and plasma samples. The PAD was able to detect specifically 10 ng.mL-1 of NS1 protein in various sample types and in 6-8 minutes. Secondly, an improved version of the PAD obtained by laser cutting was designed and tested for the detection of dengue NS1 protein and virus-specific IgM in blood and plasma. Each parameter could be detected in 8 minutes. PAD development performed on dengue fever was then applied to the detection of chikungunya virus IgM in human sera, using viral Pseudo-Particles (PPs). These synthetic antigens have proven to be powerful tools for specific IgM detection. The results obtained showed a sensitivity of 70.6% and a specificity of approximately 98% with a time to results of less than 10 minutes. The PAD showed few cross reactions with other arbovirusess. The PPS were finally characterized with different physico-chemical methods in order to determine the key factors of their performances

Повний текст джерелаMy thesis is about the "camera obscura" as an apparatus; an apparatus which differentiates between a simple device through its technical and symbolic characteristics. From this point of view, it is less likely to treat the "camera obscura" as a tool for scientists or artists, but to focus more, on the way it goes widely beyond this function through structuring thought and practice. It is possible therefore, to consider this apparatus as a full entity, in the same light as the museum, cinema, photography or perspective. It must be broken down, insisting particularly on the ratio between perspective and "camera obscura". In my opinion, the latter is paradigmatic of a new vision, such as that which appears in XVIIth century Dutch art and XIXth century German romantic paintings. If it had been used during the Middle Ages by the Arab astronomers, the "camera obscura" did not become an apparatus until the XVIIth century, because only then does it generate art, meaning and thought, notably with Kepler and Vermeer. However, Dutch art had long been ignored or studied within the Italian art criteria which concentrated more on drawings. That is why it would be time to take out this "neglected part of history" from the shadows, i. E. The "camera obscura"; and with it, colour, light and imagination. What is this world of the camera obscura ? How does it deal with the articulation between what is real and what is considered as a representation? What thoughts and which themes does it generate; what concepts does it imply? We have attempted to determine the spatiality and temporality time-frame of this technical and symbolic entity and moreover, its own philosophy

Повний текст джерелаThe effective utilisation of low calorific value fuel, as gaseous by-products of coal/biomass or industrial residual gases, provides not only excellent opportunities for low cost power generation but also for the reduction of environmental impact of combustion. The present work aims to consider the combination of oxyfuel combustion with fuel and/or oxygen preheating in order to increase thermal efficiency by heat recovery and enhance oxyfuel flame stabilization of blast furnace gas (BFG). This experimental study is performed with a burner consisting in an annular jet of BFG surrounded by two injections of oxygen (internal 'O2i' and external 'O2e'). Its dimensions are determined from an original design strategy based on an experimentally critical Damköhler number Dac*, which represents the theoretical limit of stabilisation of a turbulent diffusion BFG-O2 flame with preheated reactants. Flames structures are characterized by OH* chemiluminescence imaging. Thermal and chemical flame properties are evaluated by temperature and radiative flux analysis and pollutant emissions measurements. The 2D aerodynamic fields of reactive flows are determined by velocity measurements by PIV. Four LCV flames structures are resulting from this burner configuration. Without preheating, two concentric flames, internal 'O2i-BFG' and external 'BFG-O2e', are anchored at the burner (Type A) at low thermal power. When increasing the latter, the external flame BFG-O2e manifests some local fluctuations (Type B) or is lifted-off (Type C). With reactants preheating, the BFG-O2e flame is always anchored at the burner tip and the O2i-BFG flame could have local extinction zone for very high values of internal oxygen velocity (Type D). The results highlight a good agreement between theoretical and experimental critical velocity UC* which significantly increases with preheating. The aerodynamics study points out the transitions between the different flames structures. At semi-industrial scale, flames show similar structures to those obtained at laboratory scale. This validates the burner design strategy of preheated oxyfuel combustion adapted to LCV fuels, as well as the scale up criteria used

Повний текст джерелаThe development of the neighborhood as a scale of a more sustainable urban development takes part in a period of awareness linked to climate change for which the European Union has implemented an energy transition policy. In this context, the eco-neighborhoods are structured around two key points in terms of energy: energy efficiency and energy supply. Energy efficiency, which encompasses the energy performance of buildings and the control of energy demand, is the spearhead of existing local energy transition policies. In contrast, the low-carbon energy supply does not seem to have reached sufficient maturity to be fully implemented at the neighborhood level. Nevertheless, the analysis of eco-district projects shows the growing interest in the creation of a low carbon energy supply using local resources. This interest reflects, in particular, the willingness of some local actors to reach a degree of energy autonomy. In order to consider the neighborhood as a relevant scale for low-carbon energy supply, it is necessary to analyze the technical-economic and institutional conditions to be implemented. It reveals the need for a paradigm shift in the structuring of energy systems from centralized to decentralized systems. However, this new paradigm is conditioned by the technical and economic maturity of the infrastructures that can be installed in the district and by the ability to find a viable business model making the investment profitable on this scale. For the institutional part, it causes a modification of the relations between the actors using the energetic vectors studied (electricity and heat). The rise of new production profiles with the development of renewable energies and the emergence of new consumer profiles becoming producers, alters the energy value chain and makes it necessary to guarantee the flexibility of energy systems to ensure their correct functioning. To plan a different pathway that these relationships might take, a methodological approach based on the construction of the ideal-type was carried out. It shows the need for a new player, the energy manager, to ensure the proper functioning of the energy systems installed in the neighborhoods

Повний текст джерелаDiffuse low-grade gliomas are brain tumors of young adults. In this thesis, we focus on the segmentation and on the modeling of these tumors. In the first part of the manuscript, we study the segmentation of diffuse low-grade gliomas based on different manual and semi-automatic methods. The delineation of these tumors can be problematic because of their very infiltrating and inhomogeneous nature. In clinical practice, the monitoring of diffuse low-grade gliomas is based on the estimation of tumor volume, obtained either through a segmentation followed by a software reconstruction or through the three diameters method. As for the segmentation, it is manual and it is performed by practitioners on FLAIR-weighted or T2-weighted MRI.The three diameters approach is fast but it is difficult to implement in the case of highly infiltrating diffuse low grade gliomas or after a treatment. The manual segmentation and software-based volume reconstruction solution is time-consuming but it remains more accurate in comparison with the three diameters method. We investigate in this work the reproducibility of the manual segmentation with the OsiriX software by performing a subjective test in the Living Lab PROMETEE in TELECOM Nancy. The results of this study show that neither the practitioners' specialty nor their number of years of experience seem to have a significant impact on the quality of the segmentation. We also compare the results to those of a second test where we apply the three diameters method. Finally, we explore two semi-automatic segmentation algorithms which are, respectively, based on active contours and on the level set method. Even if automatic segmentation seems to be a promising avenue, we recommend for now the use of manual segmentation because of the diffuse nature of low-grade gliomas, which makes the tumor's contours complex to delineate. The second part of the manuscript is dedicated to the modeling of diffuse low-grade gliomas themselves or, to be more precise, to the modeling of the evolution of the tumor's diameter during chemotherapy. The therapeutic management of patients with these tumors often includes indeed chemotherapy. For this work, we focus on Temozolomide chemotherapy in first-line treatment. After the beginning of the treatment, the practitioners would like to determine the optimum time of discontinuation. We propose a statistical modeling of tumor diameter under chemotherapy. This modeling is based on linear and exponential regression models. It can predict the tumor diameter from a set of training dataset and can alert the clinician on the state of change in diameter under treatment. We hope that these models will, eventually, be used as a tool in the planning of chemotherapy in a clinical environment

Most active pharmaceutical ingredients are made largely for being administered orally. A major challenge for medicinal products development containing Active Pharmaceutical Ingredients (APIs) with low solubility, especially Class II according to Biopharmaceutical Classification System - BCS, is to add technology to the development process in order to increase the bioavailability of these APIs and at the same time ensure their stability. Thus, the objective was to develop analytical methods to characterize lyophilized solid dispersions of ibuprofen obtained by using carboxymethylcellulose (CMC), hydroxymethylpropylcellulose (HPMC) and polyethylene glycol (PEG) 6000, comparing them in terms of thermal stability. The dispersions were characterized correlating the data obtained by the following techniques: Differential Scanning Calorimetry (DSC), Differential Scanning Calorimetry Coupled to a Photovisual System (DSC-photovisual), Thermogravimetry Analysis (TG) and Vibrational Absorption using Fourier Transform Infrared Spectroscopy (FTIR) to investigate possible physical and/or chemical interaction between the ibuprofen and its excipients. For thermal stability evaluation, the products were subjected to dynamic thermogravimetric analysis, by applying Osawa kinetic model, and to isothermal analysis by Arrhenius model at temperatures of 125, 130, 135, 140 and 145 °C, showing zero order kinetics reaction for the drug in the two models applied. According to the data obtained from the thermal analysis for the characterization and stability, the lyophilized solid dispersions containing PEG as a dispersing agent were more stable. The DSC and FTIR data showed the absence of physical and chemical interaction between the formulation components.
A maioria dos insumos farmacêuticos ativos é viabilizada em grande parte para serem administrados por via oral. Um dos grandes desafios para o desenvolvimento de medicamentos contendo Insumos Farmacêuticos Ativos (IFAs) com baixa solubilidade, em especial os de Classe II relacionados no Sistema de Classificação Biofarmacêutica – SCB, é agregar tecnologias ao processo de desenvolvimento no sentido de aumentar a biodisponibilidade destes IFAs ao mesmo tempo que possa garantir a estabilidade dos mesmos. Assim, objetivou-se desenvolver metodologias analíticas para caracterizar dispersões sólidas liofilizadas de ibuprofeno obtidas com carboximetilcelulose (CMC), hidroximetilpropilcelulose (HPMC) e polietilenoglicol (PEG) 6000, comparando-as em termos de estabilidade térmica. As dispersões foram caracterizadas correlacionando-se os dados obtidos pelas técnicas de calorimetria exploratória diferencial (DSC), calorimetria exploratória diferencial acoplada ao sistema fotovisual (DSC-fotovisual), termogravimetria (TG) e espectroscopia vibracional de absorção na região do infravermelho com transformada de Fourier (FTIR), a fim de investigar possíveis interações físicas e/ou químicas entre o ibuprofeno e seus excipientes. Para avaliação da estabilidade térmica, os produtos foram submetidos à análise termogravimétrica dinâmica, aplicando-se o modelo cinético de Osawa, e isotérmica pelo modelo de Arrhenius nas temperaturas de 125, 130, 135, 140 e 145 °C, apresentando cinética de reação de ordem zero para o fármaco nos dois modelos aplicados. De acordo com os dados obtidos a partir da análise térmica para caracterização e estabilidade, as dispersões sólidas liofilizadas contendo PEG como agente dispersante mostraram-se mais estáveis. Nos dados de DSC e FTIR mostraram a ausência de interação física e química entre os componentes da formulação.
