This article examines the significance of the body and its sensory and embodied aspects associated with a historical milieu and set of practices associated with ‘rave’ subculture and its relationship to fashion creativity. It focuses on a personal fashion archive that documents menswear designed in the late 1990s and early 2000s. Using an autoethnographic approach, the study investigates how the design of the garments in the archive was shaped by ways of experiencing and understanding the body that integrated the embodied experiences of moving and dancing with electronic music, the embodied experience of dressing, and the embodied experiences of designing men’s fashion in the years that followed. While rave and electronic dance music cultures received considerable scholarly attention in the mid- to late 1990s, less attention was devoted to men’s fashion and the interaction between fashion design, embodied experience and the rave sensoria. Moreover, while this study lays at the intersection rave and electronic dance music culture, fashion and design, all of which are understood to have European and North American origins, the article considers the way those practices took a unique shape within an Australian context. The contribution aims to provide insight into fashion as part of situated and embodied practices, that take place in local milieus, and the way fashion creativity can be understood not as surface ‘ripples’ moving out from global fashion centres or trickle-down versions of ‘authentic’ fashion developed elsewhere, but as fashion creativity, shaped by global forces, energies, and technologies, and embodied and enacted via local manifestations.

This article discusses Tafsi>r Jala>lain as a literature to process Aswaja ideologization in the pesantren milieu. It is the first Islamic literature introduced by Java-Muslim scholars in the institution. The motivation is not only technical (simple description) so that Indonesian Muslim can easily understand the Qur’anic interpretation, but also ideological one. To embed the ideology Tafsi>r Jala>lain were utilized because it describes ideological interpretation of Ahlus Sunnah wal Jamaah, the primary and selected ideology among figures of pesantren. About theology it refers to Asha’iran school and regarding fiqh (Islamic Jurisprudence) it points to Shafi’ian. There are two mothods to embed the ideology to the community of pesantren mil1ieu through Tafsi>r Jala>lain: First, orally, bandongan by reading or teaching it to the students. Second, literally, by translating the Tafsi>r into the local language (Indonesian, Javanese, Maduranese and Sundanese). In turn, Aswaja ideology was rooted in the pesantren and ascertained by Nahdlatul Ulama (NU) organization founded in 1926.

Ao longo do desenvolvimento histórico de novas tecnologias, os ruídos operativos e não-intencionais de cada meio foram sendo absorvidos como parte dos repertórios estéticos dos meios audiovisuais. Na medida em que a eletricidade tornou-se um condutor cotidiano de energia, a sonoridade das falhas elétricas passou a coabitar o parque sonoro de rangidos e colisões que compunham o milieu mecânico. No design sonoro contemporâneo, os estalidos elétricos e os sons de motores coexistem com uma vazão de novos ruídos proporcionados pelas tecnoestéticas digitais. Neste artigo, a partir do caso dos jogos digitais, propomos pensar estes fantasmas da memória das mídias como processos de criação, contrapondo um entendimento dominante da memória audiovisual enquanto apenas um acervo a ser preenchido.

Les systèmes de stockage d'énergie thermique sont des éléments centraux de divers types de centrales de production d'énergie fonctionnant à l'aide de sources d'énergie renouvelables. Ces systèmes de stockage thermique de type solide/fluide peuvent être considérés comme une solution rentable dans les centrales solaires à concentration. Un tel dispositif est constitué d'un réservoir rempli d'un lit granulaire à travers lequel circule un fluide caloporteur. Cependant, dans de tels dispositifs, le réservoir pourrait être soumis à une accumulation de contraintes thermiques au cours des cycles de chargement et de déchargement en raison de la dilatation thermique différentielle entre le milieu granulaire et la paroi du réservoir. Cette thèse a été consacrée à l'étude du comportement thermomécanique du lit granulaire à l'intérieur d'un réservoir de stockage thermique de type régénérateur solide/fluide. Pour atteindre cet objectif, deux approches ont été suivies : les approches numériques et expérimentales. Un modèle numérique basé sur la méthode des éléments discrets a été développé pour décrire le comportement du réservoir sous cyclage thermique. L'évolution des contraintes appliquées aux parois de la cuve au cours des cycles thermiques, est étudiée en tenant compte à la fois des charges thermiques et mécaniques, ainsi que de la cinématique du milieu granulaire à l'échelle des particules (c'est-à-dire des éléments discrets) et de la déformation thermo-mécanqiue du réservoir. Des simulations ont été effectuées pour différentes configurations thermiques (chauffage/refroidissement homogène du réservoir sur sa hauteur ou gradient vertical de température) et différents cas de condition limite (paroi rigide, paroi du réservoir avec un coefficient de dilatation thermique supérieur au lit de roche ou inversement). Le comportement du réservoir dépend des conditions thermiques et conditions aux limites imposées. De plus, un prototype de thermocline a été conçu et construit au sein du laboratoire au CEA, visant à étudier l'accumulation de contraintes sur les cycles thermiques. Le dispositif expérimental, appelé ESPERA, est équipé de dispositifs de mesure de force installés à différentes hauteurs sur la paroi du réservoir. Les dispositifs de mesure de force ont été développés et calibrés au CEA. Leur sensibilité a également été testée en développant un autre banc expérimental, P'tit- Pousse. Des essais expérimentaux ont été réalisés permettant de prouver l'accumulation des contraintes au cours des cycles. Finalement, une comparaison entre les résultats numériques et les premiers résultats expérimentaux obtenus en fin de thèse est proposée
Thermal Energy Storage (TES) systems are central elements of various types of power plants operated using renewable energy sources. Packed bed TES can be considered as a cost effective solution in concentrated solar power plants (CSP). Such a device is made of a tank filled with a granular bed through which a heat-transfer fluid circulates. However, in such devices, the tank might be subjected to an accumulation of thermal stresses during cycles of loading and unloading due to the differential thermal expansion between the filler and the tank wall. This research was devoted to investigate the thermo-mechanical behavior of the granular bed inside a packed bed TES tank. To achieve this objective, two approaches were undertaken in this work, i.e. numerical and experimental. A numerical model was defined to describe the tank's behavior under thermal cycling based on the discrete element method (DEM). The evolution of tank wall stresses over thermal cycles, taking into account both thermal and mechanical loads, as well as the kinematics of the granular material at the particles scale (i.e. discrete elements), are studied here. The deformability of the tank itself under thermo-mechanical loads is also included in the numerical model. Simulations were performed for different thermal configurations (i.e. the tank is heated homogeneously along its height or with a moving vertical gradient of temperature) and different boundary condition cases (i.e. rigid wall, tank wall with a higher thermal expansion coeficient than the bed or inversely). The behavior of the tank is dependent on the imposed thermal and boundary conditions. In addition to this, a thermocline prototype was designed and constructed at the CEA laboratory, aiming at studying the stress accumulation over the thermal cycles. The experimental setup, called ESPERA, is equipped with force measurement devices, installed at different height positions on the wall. The force measurement devices were developed and calibrated at the CEA. Their sensitivity was also tested using a different developed setup, P'tit-Pousse. Experimental tests were carried out proving the stress accumulation over the cycles. Eventually, a comparison between the numerical results and the lately-obtained preliminary experimental measurements is proposed

L'objectif de ce travail a été de développer un modèle pour prédire le comportement d'une installation photovoltaïque (PV) dans une zone désertique maritime, afin d'optimiser la production instantanée et de maintenir les performances au fil du temps. Les données issues du monitoring d’une centrale solaire ont été analysées afin d’en extraire des indicateurs de performances et d’étudier l'impact des facteurs climatiques (température, irradiation et dépôts de poussière). Les méthodes d'analyse de performance, telles que la "transposition aux conditions de référence" (Ex. PVUSA) et "estimation des mesures de performance" (Ex. PR) ont été appliquées pour évaluer le taux de dégradation annuel de l'installation. Une première indication de la durée de vie des installations PV pour le climat de Djibouti a été obtenue, ainsi qu'une capacité à prédire l'évolution à long terme de cette centrale et des futures installations PV. Parallèlement, un modèle numérique de l'installation PV a été construit en utilisant TRNSYS, incluant les modules et les onduleurs, pour retranscrire le comportement du système PV dans son ensemble, ainsi que les conditions environnementales dans lesquelles il évolue. Le modèle inclus dans la bibliothèque TRNSYS a été amélioré à l'aide de résultats expérimentaux, en particulier en ce qui concerne la dépendance thermique. Un modèle prédictif a donc été développé combinant l'accumulation de poussière, un modèle empirique de températures et de dégradation du module. Enfin, une étude paramétrique a été réalisée avec le modèle complet, afin d'évaluer l'impact du nettoyage pour divers scénarios d’empoussièrement. Les résultats contribueront à l'optimisation de la conception et de l'exploitation des centrales solaires dans ce type de climat
The objective of this work has been to develop a model for the behavior of a photovoltaic (PV) plant in an arid zone, to optimize instantaneous production and maintain performance over time. Monitoring data were collected for a solar power plant, which were then studied to infer the impact of climatic factors (temperature, irradiation and dust deposits). Performance analysis techniques including "transposition to reference conditions" (eg. PVUSA) and "estimation of standard performance measures" (eg. PR) were applied to evaluate the annual degradation rate of the facility. A first indication of expected lifetime of PV installations for the climate of Djibouti was thus obtained, as well as a capacity to predict the long-term evolution of the plant and future installations. In parallel, a numerical model of the photovoltaic installation was constructed using TRNSYS, including the modules and inverters, to transcribe the behavior of the PV system as a whole, and also the environmental conditions in which it evolves. The model included in the standard TRNSYS library was improved with the aid of experimental results, in particular with regards the thermal dependence. A predictive model was thus developed combining dust accumulation, an empirical model of module temperatures and degradation. Finally, a parametric study was undertaken with the complete model, to evaluate the impact of cleaning schedules under various dust scenarios. The results will contribute to the optimization of solar power plant design and operation in this type of climate

L’aménagement du territoire et l’intensification agricole constituent deux causes majeures du déclin de la biodiversité. La plupart des projets d’aménagement sont tenus d’appliquer la séquence « éviter-réduire-compenser » (ERC) aux impacts générés, pour atteindre une absence de perte nette de biodiversité. La mise en place de cette séquence dans le cas de la construction de parcs éoliens se heurte à la difficulté d’évaluation et de prédiction des impacts dont la mortalité par collisions avec les chiroptères et l’avifaune. Nous avons en effet montré dans un travail préliminaire que les manques théoriques sur l’évaluation de l’impact combinés à une qualité variable des études réglementaires amènent aujourd’hui à i) un évitement et une réduction peu efficaces, ii) une compensation la plupart du temps inexistante ou hasardeuse. Face aux contraintes d'implantation, les éoliennes sont principalement installées en milieu agricole. Ce dernier, en plus de constituer un espace de production alimentaire, de support d’énergie renouvelable et de biodiversité, doit également assurer le rôle de compensation des impacts générés par la production d’énergie éolienne. Il apparaît d’autant plus urgent d’étudier cette problématique que ces impacts semblent pouvoir affecter les populations d’espèces en fort déclin. Dans un premier temps, nous avons quantifié un deuxième type d’impact des éoliennes, la répulsion exercée sur les chiroptères, jusqu’ici largement méconnue et de ce fait non pris en compte dans les projets d’implantation. Nous mettons en évidence un fort impact négatif de la présence d’éoliennes sur la fréquentation des haies par les chiroptères jusqu’à une distance minimale de 1000 m autour de l’éolienne, engendrant ainsi d’importantes pertes d’habitats. Or, à l’échelle du nord-ouest de la France, 89% des éoliennes sont implantées à moins de 200 m d’une lisière arborée (haie ou forêt), cette distance constituant une recommandation européenne. Cette étude améliore donc les connaissances liées à l’implantation des éoliennes pour optimiser l’évitement d’une partie des impacts, les rendant compensables par leur quantification. Nous avons ensuite comparé différentes mesures couramment utilisées en compensation (jachères et infrastructures agroécologiques), en développant un calcul d’équivalence multi-taxonomique entre ces mesures. Ceci a permis en toute transparence de proposer des alternatives aussi efficaces à une mesure peu acceptable (par exemple les jachères en contexte grandes cultures), maximisant les leviers de mise en place de la compensation. Enfin, nous avons évalué la faisabilité de mesures compensatoires potentiellement plus acceptables, non plus axées sur l’ajout d’éléments dans la matrice agricole, mais sur des mesures visant directement la qualité de cette matrice support de biodiversité. En se focalisant sur des changements de pratiques agricoles n’engendrant pas ou peu de pertes de rendement, nous montrons que la simplification du travail du sol peut apporter de forts bénéfices à l’avifaune et aux chiroptères. Toutefois, ce bénéfice peut fortement varier en fonction des pratiques visant à limiter l’excès de végétation spontanée généré par l’absence de labour. Une diminution du travail du sol et de l’usage d’herbicides peuvent créer des gains comparables à ceux obtenus en agriculture biologique. La thèse souligne l’urgence de reconsidérer les stratégies actuelles d’implantation et d’exploitation des éoliennes en milieu agricole, causant de fortes pertes d’habitats et une mortalité systématique. Elle montre aussi qu'en dépit des manques de connaissances limitant les possibilités d’un dimensionnement des mesures compensatoires fondé sur une quantification intégrale des impacts, nous sommes en mesure d’apporter d’ores et déjà des gains écologiques efficaces en milieu agricole grâce à des mesures acceptables par l’ensemble des acteurs
Land-use planning and agricultural intensification are two major causes of biodiversity loss. Most of development projects have to apply the mitigation hierarchy, i.e. avoid, reduce then offset impacts on biodiversity, in order to achieve the no net loss. Wind farm installation makes the mitigation hierarchy application difficult due to the lack of knowledges regarding the quantification and the prediction of impacts, characterized by collisions of birds and bats with turbines. In a preliminary study we showed that the current fail of impact assessment studies in i) the avoidance and the reduction as well as ii) the offsetting of impact, are mainly linked to a lack of theoretical knowledges and a low quality of studies. Installation constraints often imply to implement wind turbines in farmland areas. Such areas have the triple function of food production, renewable energy and biodiversity carrier, but they also have to offset impacts on biodiversity, which are generated by wind turbines. Thus, there is an urgent need to improve the consideration of impacts on biodiversity in projects, which would have underestimated effects on populations. In a first time, we quantified a new type of impact: the wind turbine revulsion on bats. This impact is so far little known and not taken into account in assessment studies for wind farm installations. We highlighted a negative long distance impact (over 1000 m) of wind turbine proximity on bat activity at hedgerows, which is a highly attractive habitat for this taxa. These strong negative impacts currently lead to high losses of habitat use. Moreover, at the region scale study (north-west France), 89% of turbines are implemented at less than the European recommendations (200 m to wooded edges -hedgerows or forests). Thus, this study improved knowledges in order to optimize avoidance of this impact and made them measurable allowing their offsetting. We then compared different commonly used offsetting measures (i.e. fallows and agroecological elements), by developing a method for calculating ecological equivalences between offset measure. This allowed in complete transparency to find alternative measures as efficiently as an initial low acceptable measure (i.e. fallows in open field area). Such a method allowed an effective implementation of measures. Finally, we assessed the ecological gain provided by new types of measures such as changes in farming practices. Unlike classic measures which are usually an implementation of new elements in the landscape, changes in farming practices consist in quality improving of arable land features. Because we studied changes which do not implies losses of yield, or low in first years after changes, such measures are potentially more acceptable for farmers. We showed that tillage and herbicide reduction could positively impact birds and bats. However, to reduce tillage (i.e. no ploughing) implies to adapt the method to control weeds, previously performed by ploughing. Several possibilities can be used such as cover cropping or herbicide use intensification. In this context, our results also highlighted that positive impacts could vary significantly among underlying weed control possibilities. For instance, tillage reduction, when one herbicide pass is removed, generates as much ecological gain than organic farming system. This PhD thesis highlights the urgent need to adapt wind energy planning and these exploitation in farming areas, due to high habitat loss and systematic mortality. This thesis also shows that despite the current lack of knowledges, preventing to design offsetting measures facing to quantified impacts, implementation of acceptable measures for stakeholders may provide effective gains for bats and birds

Resumo:
La performance d’un module photovoltaïque est conditionnée par l’environnement dans lequel il est installé. En effet, la quantité d’énergie solaire convertie en électricité dépend de l’irradiance incidente sur le module. Les progrès dans l’intégration des modules photovoltaïques sur bâtiment et la diminution de leurs coûts amènent à considérer le potentiel solaire en milieu urbain, en toiture mais aussi en façade. En milieu urbain, la densité des bâtiments limite les apports solaires en façade par la présence de masques. La volonté publique encourage une augmentation de la production locale d’énergies renouvelables. Il est alors nécessaire de se doter d’outils numériques permettant d’évaluer avec précision le potentiel solaire en ville, et ainsi évaluer la rentabilité d’installations photovoltaïques. Il s’agit en particulier d’évaluer les apports solaires issus des réflexions sur les différentes surfaces composant la scène urbaine. Les problématiques d’intégration visuelle, soulevant la question des couleurs et des spectres incidents sur les surfaces dans différentes gammes de longueurs d’ondes doivent également être considérées Enfin, ces outils doivent également permettre d’évaluer l’impact d’une intégration photovoltaïque en milieu urbain afin d’éviter de renforcer les phénomènes d’îlot de chaleur. Les travaux de thèse se sont donc focalisés sur les méthodes de simulation d’ensoleillement en milieu urbain, au travers du développement de deux stratégies de modélisation (radiosité et lancer de rayons). Les modèles de simulation sont comparés sous des hypothèses de réflexions optiques équivalentes, permettant une validation des hypothèses utilisées dans chacune des méthodes. Parallèlement, une qualification des propriétés optiques de matériaux typiques de l’environnement urbain permet la construction de modèles de réflexion optiques basés sur les distributions de réflectivité bidirectionnelles (BRDF en anglais). Ces modèles, injectés dans les modèles d’irradiance, permettent d’évaluer la part d’énergie issue des différents modes de réflexion. Par ailleurs, des mesures d’irradiances sont réalisées en milieu extérieur. Un banc de test est conçu de sorte à mesurer les irradiances perçues en façade et au sol. Différentes configurations sont testées dans via cette maquette. Les mesures obtenues sont alors confrontées aux résultats numériques sous conditions réelles, permettant une validation des modèles
The performance of a photovoltaic module is conditioned by the environment in which it is installed. Indeed, the amount of solar energy converted into electricity depends on the incident irradiance on the module. Progress in the integration of photovoltaic modules on buildings and the reduction of their costs leads us to consider the solar potential in urban environments, both on roofs and facades. In an urban environment, the density of buildings limits solar gain on the facade by the presence of masks. Public institutes encourages an increase in the local production of renewable energies. It is therefore necessary to acquire digital tools to accurately assess the solar potential in cities, and thus evaluate the profitability of photovoltaic installations. In particular, it is necessary to evaluate the solar contributions resulting from reflections on the various surfaces that make up the urban scene. Visual integration issues, raising the question of colours and incident spectra on surfaces in different wavelength ranges must also be considered. Finally, these tools must also make it possible to assess the impact of photovoltaic integration in an urban environment in order to avoid reinforcing heat island phenomena. The PhD work is therefore focused on methods for simulating sunshine in an urban environment, through the development of two modelling strategies (radiosity and ray throwing). The simulation models are compared under the hypotheses of equivalent optical reflections, allowing a validation of the hypotheses used in each of the methods. At the same time, a qualification of the optical properties of typical materials from the urban environment allows the construction of optical reflection models based on Bidirectional Reflectivity Distributions Functions (BRDF). These models are integrated into the irradiance models. Therefore, it possible to evaluate the ratio of energy resulting from the different reflection modes. In addition, irradiance measurements are carried out in an external environment. A test bench is designed to measure the irradiances perceived on the facade and on the ground. Different configurations are tested using this mock-up. The measurements obtained are then compared with the numerical results under real conditions, enabling the models to be validated

Resumo:
L'hydrate de méthane est un cristal non-stœchiométrique dans lequel les molécules d'eau forment des cages liées par liaison hydrogène qui piégent des molécules de méthane. Des ressources abondantes en hydrate de méthane peuvent être trouvées sur Terre, en particulier dans les roches poreuses minérales (par exemple, l'argile, le permafrost, les fonds marins, etc.). Pour cette raison, la compréhension de la thermodynamique et de la cinétique de formation de l'hydrate de méthane confiné dans des milieux poreux suscite beaucoup d'attention. Dans cette thèse, nous combinons la modélisation moléculaire et des approches théoriques pour déterminer la thermodynamique et la cinétique de formation de l'hydrate de méthane confiné dans des milieux poreux. Tout d'abord, l'état de l'art en matière de thermodynamique et de cinétique de formation de l'hydrate de méthane est présenté. Deuxièmement, différentes stratégies de simulation moléculaire, y compris des calculs d'énergie libre utilisant l'approche de la molécule d'Einstein, la méthode de coexistence directe et la technique textit{hyperparallel tempering}, sont utilisées pour évaluer la stabilité de l'hydrate de méthane à différentes températures et pressions. Troisièmement, parmi ces stratégies, la méthode de coexistence directe est choisie pour déterminer le déplacement du point de fusion lors du confinement dans des pores, $Delta T_m = T_m^{pore} - T_m^{bulk} $ où $ T_m^{pore}$ et $T_m^{bulk}$ sont les températures de fusion d'hydrate de méthane non confiné et confiné. Nous avons constaté que le confinement diminue la température de fusion, $T_m^{pore} < T_m^{bulk} $. Le changement de température de fusion en utilisant la méthode de la coexistence directe est cohérent avec l'équation de Gibbs-Thompson qui prédit que le décalage de la température de fusion dépend linéairement de l'inverse de la taille des pores, $Delta T_m/T_m^{bulk} sim k_{GT}/ D_p$. La validité quantitative de cette équation thermodynamique classique pour décrire de tels effets de confinement et de surface est également abordée. Les tensions de surface des interfaces hydrate-substrat et eau-substrat sont déterminées à l'aide de la dynamique moléculaire pour valider quantitativement l'équation de Gibbs-Thompson. Des simulations de dynamique moléculaire sont également effectuées pour déterminer les propriétés thermodynamiques importantes de l'hydrate de méthane non confiné et confiné: (a) conductivité thermique $lambda$ en utilisant le formalisme de Green-Kubo et la fonction d'autocorrélation du flux thermique; (b) expansion thermique $alpha_P$ et compressibilité isotherme $kappa_T$. Enfin, des conclusions et perspectives pour des travaux futurs sont présentées
Methane hydrate is a non-stoichiometric crystal in which water molecules form hydrogen-bonded cages that entrap methane molecules. Abundant methane hydrate resources can be found on Earth, especially trapped in mineral porous rocks (e.g., clay, permafrost, seafloor, etc.). For this reason, understanding the thermodynamics and formation kinetics of methane hydrate confined in porous media is receiving a great deal of attention. In this thesis, we combine computer modeling and theoretical approaches to determine the thermodynamics and formation kinetics of methane hydrate confined in porous media. First, the state-of-the-art on the thermodynamics and formation kinetics of methane hydrate is presented. Second, different molecular simulation strategies, including free energy calculations using the Einstein molecule approach, the direct coexistence method, and the hyperparallel tempering technique, are used to assess the phase stability of bulk methane hydrate at various temperatures and pressures. Third, among these strategies, the direct coexistence method is chosen to determine the shift in melting point upon confinement in pores, $Delta T_m = T_{m}^{pore} - T_{m}^{bulk}$ where $T_m^{pore}$ and $T_m^{bulk}$ are the melting temperatures of bulk and confined methane hydrate. We found that confinement decreases the melting temperature, $T_m^{pore}

La première partie est une étude bibiographique. Nous étudions les conditions thermodynamiques de stabilité des hydrates dans un milieu bulk et la composition des phases solide et liquide. Nous décrivons ensuite les écoulements dans les milieux poreux. Enfin, nous fusionnons les deux approches en étudiant l'influence du confinement sur la stabilité des hydrates. Un champ offshore (Blake Ridge) et un champ on-shore (Mallik) sont décrits dans le détail. Ce dernier servira de base aux simulations numériques ultérieures.

La deuxième partie est consacrée aux expériences. Leur but est de mesurer la perméabilité d'un sédiment contenant des cristaux. Pour nous rapprocher des conditions géologiques naturelles, les cristaux sont réalisés en l'absence de phase gazeuse. Il s'avère que les hydrates se forment de manière très hétérogène dans le milieu poreux et ceci rend les mesures non représentatives. Nous pensons que ce résultat est général et qu'à l'échelle de temps du laboratoire, la formation d'hydrates de gaz répartis uniformément dans un milieu poreux est très difficile. Pour contourner cette difficulté, nous montrons de manière théorique que les cristaux de glace ont un comportement analogue aux cristaux d'hydrate (du point de vue des forces de Van der Waals qui gouvernent l'agglomération). Ceci nous permet de calculer la constante de Hamaker des hydrates. La deuxième série d'expériences s'intéresse donc à la perméabilité d'un milieu poreux non consolidé et sous contrainte dont les pores sont occupés par des cristaux de glace. Deux populations de grains de silice sont utilisées pour former le milieu poreux : 3 mm et 200 microns. Avec les gros grains, les résultats font apparaître deux seuils : pour des saturations plus faibles que le seuil inférieur, la présence des cristaux n'affecte pas la perméabilité. Pour des saturations plus grandes que le seul supérieur, la perméabilité est quasiment nulle (phénomène de percolation). Entre les deux, la perméabilité décroît exponentiellement en fonction de la saturation. Avec les grains fins, la perméabilité décroît avec la même vitesse.

La dernière partie est une étude numérique sur le champ Mallik. Après avoir posé les équations décrivant les transferts massiques et de chaleur dans l'espace et au cours du temps, nous étudions un cas limite unidimensionnel. Ceci nous permet de voir l'influence de la courbe 'Perméabilité = f(saturation)' obtenue expérimentalement sur la quantité de gaz produite. Le code proposé permet également d'évaluer différents scénarios de production, dont la dépressurisation assistée par formation de glace.

More than fifteen years after the introduction of direct election, the mayors are still the most popular politicians in Italy. The personal relationship set up with the citizens and the strengthening of the city councils has restored energy and stability to the action of the municipal administrations. Nevertheless, these institutional reforms, while important, have failed to guarantee good government. The effects of the mayoral reform are, in fact, considerably different from one city to another, and from one type of policy to another. What does this variety of results derive from? The book provides an answer to this question through an investigation of the decisional processes of around a hundred "local collective assets" in six large metropolitan cities. To explain the different outcomes – in addition to the "council effect", that is, the relevance of policy, and the "sector effect", the relevance of the different decisional milieus – the authors also underscore the role of the "governance effect", namely the different approaches to decision-making and building consensus on urban policies.

The challenge of meeting the Corporate Average Fuel Economy (CAFE) standards of 2025 has resulted in the development of systems that utilize alternative energy propulsion technologies. To date, the use of solar energy as an auxiliary energy source of on-board fuel has not been extensively investigated, however. The authors investigated the design parameters and techno-economic impacts within a solar photovoltaic (PV) system for use as an on-board auxiliary power source for the internal combustion engine (ICE) vehicles and plug-in electric vehicles (EVs). The objective is to optimize, by hybridizing, the conventional energy propulsion systems via solar energy based electric propulsion system by means of the on-board PVs system. This study is novel in that the authors investigated the design parameters of the on-board PV system for optimum well-to-tank energy efficiency. The following design parameters were analyzed: the PV device, the geographical solar location, thermal and electrical performances, energy storage, angling on the vehicle surface, mounting configuration and the effect on aerodynamics. A general well-to-tank form was derived for use in any other PV type, PV efficiency value, or installation location. The authors also analyzed the techno-economic value of adding the on-board PVs for ICE vehicles and for plug-in EVs considering the entire Powertrain component lifetime of the current and the projected price scenarios per vehicle lifetime, and driving by solar energy cost ($ per mile). Different driving scenarios were used to represent the driving conditions in all the U.S states at any time, with different vehicles analyzed using different cost scenarios to derive a greater understanding of the usefulness and the challenges inherent in using on-board PV solar technologies. The addition of on-board PVs to cover only 1.0 m2 of vehicle surfaces was found to extend the daily driving range to up to 2 miles for typical 2016 model vehicles, depending upon on vehicle specifications and destination, however over 7.0 miles with the use of extremely lightweight and aerodynamically efficient vehicles in a sunny location. The authors also estimated the maximum possible PV installation area via a unique relationship between the vehicle footprint and the projected horizontal vehicle surface area for different vehicles of varying sizes. It was determined that up to 50% of total daily miles traveled by an average U.S. person could be driven by solar energy, with the simple addition of on-board PVs to cover less than 50% (3.25 m2) of the projected horizontal surface area of a typical mid-size vehicle (e.g., Nissan Leaf or Mitsubishi i-MiEV). Specifically, the addition of the proposed PV module to a 2016 Tesla Model S AWD-70D vehicle in San Diego, CA extended the average daily range to 5.2 miles in that city. Similarly, for the 2016 BMW i3 BEV in Texas, Phoenix, and North Carolina, the range was extended to more than 7.0 miles in those states. The cost of hybridizing a solar technology into a vehicle was also estimated for current and projected prices. The results show for current price scenario, the expense of powering an ICE vehicle within a certain range with only solar energy was between 4 to 23 cents per mile depending upon the vehicle specification and driving location. Future price scenarios determined the driving cost is an optimum of 17 cents per mile. However, the addition of a PV system to an EV improved the economics of the system because of the presence of the standard battery and electric motor components. For any vehicle in any assumed location, the driving cost was found to be less than 6.0 cents per mile even in the current price scenario. The results of this dynamic model are applicable for determining the on-board PV contribution for any vehicle size with different powertrain configurations. Specifically, the proposed work provides a method that designers may use during the conceptual design stage to facilitate the deployment of an alternative energy propulsion system toward future mobility.

<div class="section abstract"><div class="htmlview paragraph">This paper presents a case study conducted by Isuzu Technical Center of America on calculating Lithium-ion battery degradation patterns. For hybrid electric cars, plug-in hybrid electric vehicles (PHEVs), and all-electric vehicles, energy storage technologies, and batteries are often necessary (HEVs). As soon as these batteries are used for the first time, they begin to deteriorate. This is due to the battery's inherent chemistry which results in inevitable chemical reactions that happen inside the battery while it is running. ISUZU engineers are using the GT-AutoLion tool to predictively model the electrochemical processes within Lithium-ion cells using a fast and reliable, electrochemical, physics-based approach and real-world battery information. To feed this tool, we gathered valuable battery information from a light-duty BEV Prototype. The information was recorded at 3 different milestones: BOT (beginning of the test), 7500 miles, and 15000 miles. After analyzing this data at each milestone, it is observed that the battery was degraded by 8.09% after a 7500-mile run and decreased significantly to 10.42% of overall battery capacity at 15k miles, such similar patterns were also observed in the developed battery model, The battery degradation patterns generated by the developed battery model will be used to predict battery performance and improve range estimation by ISUZU.</div></div>

Over the past two decades, several options have emerged as alternatives to traditional internal combustion engine-powered transportation systems. The alternative power sources garnering the most commercial interest have been hydrogen fuel-cells, battery-powered electric, propane, biodiesel, ethanol, and compressed natural gas. “Transportation Integrating Green Energy Resources” (TIGER)™ is a prototype hybrid vehicle that optimizes consumer desire for performance, alternative fuels, and environmental emissions reduction. It is powered by a combination of an electric motor and a biodiesel internal combustion engine. It is a two-passenger vehicle with a solarelectric, zero-emissions primary energy source for the daily commute while still permitting long-range travel utilizing the range-extension provided by the biodiesel engine. The average daily commute in the United States is less than 50 miles. During daily commuting use, the vehicle will operate solely as a solar-electric car. The electric vehicle (EV) system will be charged by deployable solar cells on its top surface while it is parked in a sun-lit parking lot during the workday. This charge will be sufficient to replenish energy used during a 50-mile commute. The commute is patterned as being comprised of 40 mph segments representing travel on arterial city roads and a 70-mph segment representing interstate highway travel. The biodiesel engine functions as the secondary power source to permit long-range trips with a refueling stop planned for around 350 miles; comparable to a conventional vehicle. The paper will report key elements of the vehicle design, including trade-offs between energy efficiency and passenger comfort/safety. Details of the various sub-systems such as the energy sources, the hybrid drive-train, and subsystem integration will be presented.

INDOT plans to invest nearly $100 million to build a statewide electric vehicle (EV) charging network as part of the National Electric Vehicle Infrastructure Formula Program. SPR-4509 Phase-I identified energy EV charging deserts in Indiana for long-distance trips. SPR-4509 Phase-II further examines the charging stations' impact on EV long-distance trips in Indiana. Using an agent-based simulation model, the number of charges, vehicle miles traveled, energy used during the trip, and energy used during charging were estimated for nine different cases. High EV daily charging demand areas in Indiana were shown in ArcGIS based on multiple scenarios of different charging station construction phases and EV market penetration rates. The study findings can inform the state’s EV charging plan development.

Nepalese agriculture is facing a number of challenges, including a shrinking cropped area, principally due to land use changes, low competitiveness, and increasing impacts of climate change, leading to a volatile food security situation. Likewise, changing dietary patterns – characterised by less diverse foods and more consumption of energy-dense ultraprocessed and packaged foods – has been the leading cause of malnutrition, especially among children and adolescents. Promoting a millet-based food system has the potential to improve food security and nutrition in the country. However, there has been a declining trend in the production and consumption of millets owing to a number of reasons.

Az elemzés azt vizsgálja, hogy a megújuló energiaforrásokra történő átállás hogyan hat napjaink nagyhatalmi versengésére, illetve azon belül Kína dominanciája a szektorban milyen kockázatot rejt elsősorban az USA számára. A megújuló energiaforrások jellegzetességeiből adódóan várhatóan egyetlen ország sem lesz képes domináns termelővé válni világszinten, az energia mint külpolitikai eszköz pedig előreláthatólag veszít jelentőségéből. Kína dominanciája a megújulóenergia-termelési eszközök terén vitathatatlan, ám az elemzés megállapításai szerint ez a pozíció önmagában nem tekinthető nemzetbiztonsági kockázatnak az USA számára. Kínát nem nemzetközi befolyásszerzési, hanem a belső stabilitással, kereskedelmi lehetőségekkel, illetve a kőolajimport-kitettséggel kapcsolatos szempontok motiválták abban, hogy versenytársainál gyorsabban építse fel megújulóenergia-iparát. Egy esetleges kínai „napelemembargó” az USA-val vagy az EU-val szemben elsősorban nem a geopolitikai erőviszonyokat befolyásolná, hanem a globális klímacélok elérését késleltetné. Kína inkább érdekelt abban, hogy a jövő egyik kulcsiparágának éllovasa maradjon, és kihasználhassa az ezzel járó kereskedelmi és technológiai innovációs előnyöket.

A narrow focus on electrification and elimination of tailpipe emissions is unlikely to achieve decarbonization objectives. Renewable power generation is unlikely to keep up with increased demand for electricity. A focus on tailpipe emissions ignores the significant particulate pollution that “zero emission” vehicles still cause. It is therefore vital that energy efficiency is improved. Active travel is the key to green economic growth, clean cities, and unlocking the energy saving potential of public transport. The Challenges of Vehicle Decarbonization reviews the urgent need to prioritize active travel infrastructure, create compelling mass-market cycling options, and switch to hybrid powertrains and catenary electrification for long-haul heavy trucks. The report also warns of the potential increase in miles travelled with the advent of personal automated vehicles as well as the pitfalls of fossil-fuel derived hydrogen power.

Pipelines are by far the most important mode of petroleum transportation in the United States because of their remarkable efficiency and low transportation cost. Pipelines carry two-thirds of the energy consumed by our nation and are recognized as the safest and most economical way to distribute vast quantities of oil and gas from production fields to refineries to consumers for a foreseeable future. This sophisticated network of gathering and distribution systems comprises 2.3 million miles of pipelines-varying in size from 2 inches to 60 inches in diameter. Pipelines are vital to a nation's economy and are a significant part of national critical infrastructure. The pipeline infrastructure and the volume of products transported have continued to grow as demand for energy has increased. Over the next two decades, the demand for energy is projected to reach record levels. This increased demand for energy combined with the expansion of the cities and suburban areas will require the pipeline infrastructure not only to expand but to reliably and safely deliver energy services in support of the nation's economy. The United States has a well-developed system for the protection of the public and the environment from the dangers of oil and gas pipeline failures. However, there is always a chance that a pipeline can leak. Pipeline leaks can be dangerous to people, to the natural environment, to public land, and to private property. Furthermore, the tragic events of the September 11 t terrorist attacks have focused the attention on the security of the nation's energy sources and the critical energy and transportation infrastructure systems. Therefore, pipeline security and safety has become a high-profile, national concern.

Resumo:
The study provides details on distribution networks, access to finance, type of technologies and incidence on policies for the development and scaling up of models led by private entrepreneurs committed to providing electricity to the last mile population in Latin America. This ideal scenario is strengthened by the recent Paris climate change agreement which seeks to increase international aid to support the transfer of sustainable technologies and the generation of resilience tools for climate change.
