Résumé :
This study has built on research on today's modern organizations with cloud computing to lay the foundations for a comprehensive and systematic theorization of Enterprise Social Systems. The trend toward virtuality marks a fundamental transformation in space-time parameters in communications. This is especially so in the context of rapid current advancements in IT such as cloud computing, as well as numerous other technological fronts. Current IT trends show that increased spatio-temporal plasticity heightens the effectiveness and the efficiency of predominantly Enterprise Social Systems in the cloud computing environment. In particular, subject oriented asynchronous communications experience greater inferred plasticity and event oriented synchronous communications experience greater referred plasticity. Finally, Enterprise Social Systems vary in their degree of virtuality based on the perspective of the relevant stakeholder group considered.

Hammond, N. G. L. « The Battle between Philip and Bardylis ». Antichthon 23 (1989) : 1–9. http://dx.doi.org/10.1017/s0066477400003658.
Résumé :
The defeat of Bardylis ‘the king of the Illyrians‘ was one of the decisive battles of ancient history. It ended forty years of military ascendancy by the Illyrians, during which huge losses had been inflicted on the Molossians, Amyntas III had twice been driven out of Macedonia, and Perdiccas III and 4,000 Macedonians had been killed ‘in a great battle’ of359B.C.(Diod. 16.2.5). One reason for that ascendancy was that the Illyrians adopted Greek hoplite equipment and tactics earlier than their opponents. The victory of Philip marked the beginning of Macedonia’s progress to a military supremacy, of which the marks were the infantry fighting with the pike (sarissa) and the cavalry exploiting a break in an enemy line. Evidence about the battle is provided only by Diodorus and Frontinus, and there are uncertainties about the background to the affair. I think that progress can be made if we ask the appropriate questions.

Résumé :
George VI Ice Shelf is the largest ice shelf on the west coast of the Antarctic Peninsula, covering a total area of 25 000 km2. The northern ice front of George VI Ice Shelf presently marks the southernmost occurrence of recent ice-shelf retreat on the Antarctic Peninsula and according to some predictions the ice shelf is close to its thermal limit of stability. If these predictions are accurate and we are witnessing the first stages of retreat then it is critical that we take the opportunity to examine the ice shelf in its pre-collapse phase. This paper provides a review of the geological evolution, glaciology and interactions between the ocean and the atmosphere. We also discuss the present behaviour of the ice shelf, in the context of recent retreat of its northern and southern ice fronts, and outline several possible mechanisms for future ice shelf collapse. What emerges from this review is that the stability of George VI Ice Shelf is sensitive not only to the recent rapid regional atmospheric warming on the Antarctic Peninsula which has led to the gradual retreat of the northern and southern ice shelf fronts, but also to changes in ocean circulation, particularly intrusions of warm Upper Circumpolar Deep Water onto the continental shelf. It is likely that any future change in the stability of George VI Ice Shelf will involve a combined atmospheric and oceanic forcing.

Résumé :
AbstractA high-resolution pollen record of the Atlantic rain forest (ARF) biome from the coastal Serra do Tabuleiro mountains of southern Brazil documents an 11,960 yr history of vegetation and climate change. A marked expansion of Weinmannia into the grassland vegetation marks the latter part of the Younger Dryas, reflecting warm and relatively wet conditions. Between 11,490 and 9110 cal yr BP, grasslands became dominant again, indicating a long cold and dry phase, probably in response to the stronger influence of cold South Atlantic seawater and to Antarctic cold fronts. Between 9110 and 2640 cal yr BP, four distinct phases with strong or moderate expansions of different ARF biome taxa were recorded, reflecting warmer and relatively dry conditions with changes in rainfall and length of the annual dry season. After 2640 cal yr BP, the modern ARF biome became established with high amounts of ferns, reflecting somewhat cooler and wetter conditions with a reduced annual dry season. In particular, after 1000 cal yr BP tree ferns increased, reflecting wetter conditions with no dry season.

Résumé :
As the world’s second largest sand sea and one of the most important dust sources to the global aerosol system, the formation of the Taklimakan Desert marks a major environmental event in central Asia during the Cenozoic. Determining when and how the desert formed holds the key to better understanding the tectonic–climatic linkage in this critical region. However, the age of the Taklimakan remains controversial, with the dominant view being from ∼3.4 Ma to ∼7 Ma based on magnetostratigraphy of sedimentary sequences within and along the margins of the desert. In this study, we applied radioisotopic methods to precisely date a volcanic tuff preserved in the stratigraphy. We constrained the initial desertification to be late Oligocene to early Miocene, between ∼26.7 Ma and 22.6 Ma. We suggest that the Taklimakan Desert was formed as a response to a combination of widespread regional aridification and increased erosion in the surrounding mountain fronts, both of which are closely linked to the tectonic uplift of the Tibetan–Pamir Plateau and Tian Shan, which had reached a climatically sensitive threshold at this time.

Narbonne, Guy M., Marc Laflamme, Carolyn Greentree et Peter Trusler. « Reconstructing a lost world : Ediacaran rangeomorphs from Spaniard's Bay, Newfoundland ». Journal of Paleontology 83, no 4 (juillet 2009) : 503–23. http://dx.doi.org/10.1666/08-072r1.1.
Résumé :
Ediacaran fronds at Spaniard's Bay on the Avalon Peninsula of Newfoundland exhibit exquisite, three-dimensional preservation with morphological features less than 0.05 mm in width visible on the best preserved specimens. Most of the nearly 100 specimens are juvenile rangeomorphs, an extinct Ediacaran clade that numerically dominated the early evolution of complex multicellular life. Spaniard's Bay rangeomorphs are characterized by cm-scale architectural elements exhibiting self-similar branching over several fractal scales that were used as modules in construction of larger structures. Four taxa of rangeomorph fronds are present – Avalofractus abaculus n. gen. et sp., Beothukis mistakensis Brasier and Antcliffe, Trepassia wardae (Narbonne and Gehling), and Charnia cf. C. masoni Ford. All of these taxa exhibit an alternate array of primary rangeomorph branches that pass off a central stalk or furrow that marks the midline of the petalodium. Avalofractus is remarkably self similar over at least four fractal scales, with each scale represented by double-sided rangeomorph elements that were constrained only at their attachment point with the higher-order branch and thus were free to rotate and pivot relative to other branches. Beothukis is similar in organization, but its primary branches show only one side of a typical rangeomorph element, probably due to longitudinal branch folding, and the position of the individual branches was moderately constrained. Trepassia shows only single-sided branches with both primary and secondary branches emanating from a central stalk or furrow; primary branches were capable of minor pivoting as reflected in bundles of secondary branches. Charnia shows only single-sided primary branches that branch from a zigzag central furrow and that were firmly constrained relative to each. This sequence provides a developmental linkage between Rangea-type and Charnia-type rangeomorphs. Avalonian assemblages show a wide array of rangeomorph constructions, but later Ediacaran assemblages contain a lower diversity of rangeomorphs represented mainly by well-constrained forms.

Lichtenstein, Eli B. « On the Ways of Writing the History of the State ». Foucault Studies 1, no 28 (27 septembre 2020) : 71–95. http://dx.doi.org/10.22439/fs.v1i28.6074.
Résumé :
Foucault’s governmentality lectures at the Collège de France analyze the history of the state through the lens of governmental reason. However, these lectures largely omit consideration of the relationship between discipline and the state, prioritizing instead raison d’État and liberalism as dominant state technologies. To remedy this omission, I turn to Foucault’s early studies of discipline and argue that they provide materials for the reconstruction of a genealogy of the “disciplinary state.” In reconstructing this genealogy, I demonstrate that the disciplinary state marks the “dark side” of the liberal state, a dark side which is, more-over, largely obscured in the governmentality lectures. I further construe the difference be-tween this early genealogy of the state and the later governmental studies in methodologi-cal terms. At stake in this difference is the historiographic status of capitalism and social conflict. Foucault’s governmentality lectures employ what I term an “idealist disavowal,” thereby treating capitalism and social conflict as irrelevant to the history of the state. The early disciplinary studies, on the other hand, enact a “materialist avowal,” by which these objects are avowed as central to the explanation of how and why the state develops. Final-ly, I argue that Foucault’s governmental genealogy of the liberal state is explanatorily and analytically incomplete, while the genealogy of the disciplinary state contributes to its completion on both fronts.

Monthly Notices of the Royal Astronomical Society 494, no 2 (20 mars 2020) : 2244–53. http://dx.doi.org/10.1093/mnras/staa777.
Résumé :
ABSTRACT We report results on deep Jansky Very Large Array (VLA) A-configuration observations at 22 GHz of the hotspots of the radio galaxies 3C 227 and 3C 445. Synchrotron emission in the optical on scales up to a few kpc was reported for the four hotspots. Our VLA observations point out the presence of unresolved regions with upper limit to their linear size of about 100 pc. This is the first time that such compact components in hotspots have been detected in a mini-sample, indicating that they are not a peculiar characteristic of a few individual hotspots. The polarization may reach values up to 70 per cent in compact (about 0.1 kpc scale) regions within the hotspot, indicating a highly ordered magnetic field with size up to a hundred parsecs. On larger scales, the average polarization of the hotspot component is about 30–45 per cent, suggesting the presence of a significant random field component, rather than an ordered magnetic field. This is further supported by the displacement between the peaks in polarized intensity and in total intensity images that is observed in all the four hotspots. The electric vector position angle is not constant, but changes arbitrarily in the central part of the hotspot regions, whereas it is usually perpendicular to the total intensity contours of the outermost edge of the hotspot structure, likely marking the large-scale shock front. The misalignment between X-ray and radio-to-optical emission suggests that the former is tracing the current particle acceleration, whereas the latter marks older shock fronts.

Résumé :
The World Trade Organization (WTO) Panel Report in Australia – Anti-Dumping Measures on A4 Copy Paper (Australia – A4 Copy Paper) marks a significant development of the multilateral rules on anti-dumping. Under certain circumstances, WTO agreements permit members to impose anti-dumping measures to counteract the injurious effect of dumping on domestic industries, typically through import duties. The Report is the first to examine in detail when an anti-dumping authority may determine that a “particular market situation” exists in the country of exportation under Article 2.2 of the WTO Anti-Dumping Agreement, potentially justifying the imposition of elevated remedial duties. The Report also develops the jurisprudence on how such remedies may be calculated, expounding the use of benchmark costs for the calculation of a constructed normal value (CNV) under Article 2.2.1.1. These doctrinal questions are central to the longstanding debate over how far the Anti-Dumping Agreement allows anti-dumping measures against state intervention and market distortions. On both fronts, the Australia – A4 Copy Paper panel created flexibilities for WTO members to respond to government-induced distortions. In doing so, the Report deviates considerably from the course set by the Appellate Body in the landmark EU – Biodiesel decision, which seemed to confine anti-dumping measures to responding to private action. At the same time, the panel left open several important issues relating to the adoption of CNVs and the use of benchmarks for their calculation, leaving wide latitude for investigating authorities to inflate dumping margins in practice.

Résumé :
Bien que le Courant des Malouines (CM) soit le principal soutien de la productivité élevée qui caractérise l’Atlantique Sud-Ouest il reste encore peu documenté. Cette thèse combine des données in situ et satellitaires et des sorties de modèles opérationnels, pour étudier le CM. Le CM est une émanation du courant Antarctique Circumpolaire (ACC). Il s’écoule vers le nord jusqu’à 38°S puis il retourne vers le sud formant le Courant de Retour des Malouines (CRM). Nous montrons que l’énergie turbulente de l’ACC est filtrée sur le plateau des Malouines (55°S-48°S). Nous avons découvert l'occurrence d’évènements de blocage à 48S qui coupent le CM de sa source l’ACC. Le CM devient alors le bord ouest d’une grande cellule de recirculation cyclonique. Nous avons montré que les positions des fronts du système du CM (Front Polaire, Front Subantarctique et Front du Brésil) peuvent être suivies en définissant des critères sur la densité potentielle et la hauteur de l’eau. Des eaux du sud du front polaire (FP) sont injectées dans le CM (évènements d'alimentation) et recirculent entre le CM et le CRM. Les caractéristiques des eaux de la recirculation varient dans le temps en fonction des évènements d’alimentation et de blocage. Une série temporelle de 24 ans du transport du CM à 41°S a été construite à partir de données de mouillages et d’altimétrie satellitale. Les maxima et minima du transport sont liés à des perturbations de la circulation en provenance du Bassin Argentin (et non de l’ACC): les maxima sont dus à des tourbillons détachés du FP et les minima à des anomalies anticycloniques provenant du courant de BrésilAlthough the Malvinas Current (MC) plays a key role over the Patagonian shelf in sustaining an extremely rich ecosystem it remains rather undocumented. In this thesis, we combined in situ, satellite data, and operational model outputs to study the MC. The MC is an offshoot of the Antarctic Circumpolar Current (ACC). It flows northward up to 38°S where it turns southward forming the Malvinas Return Flow (MRF). We show that a substantial portion of the mesoscale activity from the ACC is dissipated over the Malvinas Plateau. We discovered the occurrence of recurrent blocking events cutting the MC from its source, the ACC. However, the MC does not collapse as a recirculation cell is established. Criteria in potential density and dynamic topography were defined to study the MC system fronts (Polar Front, Subantarctic Front and Brazil Current Front). Waters from the South of the Polar Front (PF) are recurrently injected into the MC as pulses or feeding events. Polar waters accumulate in the recirculation region between the MC and the MRF. Variations in the water characteristics of the recirculation region are consistent with changes in the occurrence of blocking and feeding events. Combining mooring and satellite altimetric data, a 24-year long time series of the MC transport at 41 ° S was constructed. Maxima and minima of the Malvinas current transport at 41 ° S are not associated with the ACC, rather with eddies coming from the Argentine Basin. Transport maxima appear to be related with cyclonic eddied detached from the Polar Front and transport minima with large anticyclonic anomalies from the Brazil Current

Résumé :
L'océan est le plus grand réservoir d'énergie solaire de notre planète. La quantité de chaleur qu'il est capable de stocker est modulée par sa circulation complexe, opérant sur une vaste gamme d’échelles allant du centimètre à la dizaine de milliers de kilomètres. Cette thèse s'intéresse à deux types de processus océaniques: les tourbillons de mésoéchelle, d'une taille de 100 à 300 km, et les fronts de sous-mésoéchelle, d'une taille inférieure à 50 km. L'idée communément admise est que les mouvements agéostrophiques de sous-mésoéchelle sont principalement confinés à la couche de mélange océanique de surface et sont faibles dans l'océan intérieur. Cette vision classique de la dynamique océanique repose sur l'hypothèse que l'océan intérieur est en équilibre quasi-géostrophique, empêchant la formation de forts gradients de densité en profondeur. Cette thèse remet en question ce paradigme en se basant sur des observations CTD in situ à haute résolution collectées par des éléphants de mer instrumentés, des images satellite d’élévation de la surface de l’océan, et des sorties de modèle à haute résolution dans le Courant Circumpolaire Antarctique.Les résultats indiquent que les mouvements agéostrophiques sont (i) générés par le champ tourbillonnaire de mésoéchelle via des processus defrontogenèse, et (ii) ne sont pas limités à la couche de mélange de surface ; bien au contraire, ils pénètrent dans l'océan intérieur jusqu'à 1000 m deprofondeur. Ces fronts agéostrophiques de sous-mésoéchelle sont associés à d'importants flux de chaleur dirigés de l'intérieur de l'océan vers la surface, d'une amplitude comparable aux flux air-mer.Cet effet peut potentiellement altérer la capacité de stockage de chaleur de l'océan et devrait être le plus fort dans les zones tourbillonnaires telles que le Courant Circumpolaire Antarctique, le Kuroshio et le Gulf Stream, les trois courants clefs du système climatique. Il apparaît ainsi que les fronts agéostrophiques de sous-mésoéchelle représentent une voie importante, mais encore largement méconnue, pour le transport de chaleur, de nutriments et de gaz entre l'intérieur et la surface de l'océan, avec des répercussions potentiellement majeures pour les systèmes biogéochimique et climatiqueThe ocean is the largest solar energy collector on Earth. The amount of heat it can store is modulated by its complex circulation, which spans a broad range of spatial scales, from centimeters to thousands of kilometers. This dissertation investigates two types of physical processes: mesoscale eddies (100-300 km size) and submesoscale fronts (£ 50 km size). To date, ageostrophic submesoscale motions are thought to be mainly trapped within the ocean surface mixed layer, and to be weak in the ocean interior. This is because, in the classical paradigm, motions below the mixed layer are broadly assumed to be in quasigeostrophic balance, preventing the formation of strong buoyancy gradients at depth. This dissertation introduces a paradigm shift; based on a combination of high-resolution in situ CTD data collected by instrumented elephant seals, satellite observations of sea surface height, and high-resolution model outputs in the Antarctic Circumpolar Current, we show that ageostrophic motions (i) are generated by the backgound mesoscale eddy field via frontogenesis processes, and (ii) are not solely confined to the ocean surface mixed layer but, rather, can extend in the ocean interior down to depths of 1 000 m. Deepreaching ageostrophic fronts are shown to drive an anomalous upward heat transport from the ocean interior back to the surface that is larger than other contributions to vertical heat transport and of comparable magnitude to air-sea fluxes. This effect can potentially alter oceanic heat uptake and will be strongest in eddy-rich regions such as the Antarctic Circumpolar Current, the Kuroshio Extension, and the Gulf Stream, all of which are key players in the climate system. As such, ageostrophic fronts at submesoscale provide an important, yet unexplored, pathway for the transport of heat, chemical and biological tracers, between the ocean interior and the surface, with potential major implications for the biogeochemical and climate systems

Sallée, Jean-Baptiste. « Les eaux modales de l'Océan Austral ». Phd thesis, Université Paul Sabatier - Toulouse III, 2007. http://tel.archives-ouvertes.fr/tel-00193791.
Résumé :
Les eaux modales Subantarctiques (SAMW) sont formées dans la profonde couche de mélange au nord du front Subantarctique (SAF) dans l'Océan Austral. Elles influencent le climat à des échelles décennales et inter-annuelles et jouent un rôle fondamental dans la ventilation de la thermocline de l'Océan Austral. Nous étudions la formation des SAMW en nous fondant sur les récents flotteurs profilants ARGO et sur les dériveurs de surface GDP. Ces jeux de données fournissent une très bonne couverture spatio-temporelle des processus à l'oeuvre dans les couches supérieures de l'Océan Austral. Depuis le lancement du programme international ARGO, le nombre de profils hydrographiques a augmenté de façon considérable dans l'Océan Austral. Une analyse de ces données a montré que les flux air-mer et les flux d'Ekman sont les forçages dominants dans la formation des SAMW. Nous avons trouvé une transition rapide, autour de 70°E, des couches de mélange peu profondes en amont vers des couches de mélange très profondes en aval. Cette transition est associée à un changement de signe de la diffusion tourbillonnaire horizontale dans les couches de surface, et à l'extension méridionale de l'ACC lorsqu'il passe autour du plateau de Kerguelen. Ces effets sont directement liés à la bathymétrie et laissent place à une région de formation des SAMW au Sud-Ouest de l'Australie.La formation des SAMW est intimement liée à la dynamique océanique Australe et à la position des principaux fronts polaires. Une deuxième étude concerne la circulation de l'ACC et la variabilité frontale. Dans cette étude, nous avons tiré parti de la complémentarité des données in situ et altimétriques afin de suivre l'évolution des deux principaux fronts de l'ACC pendant la période 1993-2005. Nous avons comparé leurs mouvements avec les deux principaux modes de variabilité atmosphérique de l'Hémisphère Sud, le mode annulaire Austral (SAM) et l'Oscillation Australe El-Niño (ENSO). La position moyenne des fronts est déterminée avant tout par les fonds océaniques. Cependant, nous avons trouvé que dans les régions à fond plat, les fronts forment de grands méandres dus à l'activité tourbillonnaire et aux forçages atmosphériques.
En parallèle, nous avons développé une nouvelle estimation de la distribution circumpolaire de la diffusion dans l'Océan Austral. La diffusion n'a presque jamais été étudiée à partir de données in situ dans cet océan. Nous avons calculé une estimation du coefficient de diffusion tourbillonnaire à partir d'une analyse statistique de dix années de trajectoires de dériveurs de surface. Nous avons cartographié ce coefficient dans l'Océan Austral, puis nous l'avons paramétré à partir de données altimétriques pour pouvoir en étudier l'évolution inter-annuelle et en faciliter l'utilisation dans le futur. Cette étude montre que l'Océan Austral est fortement diffusif au nord de l'ACC, et particulièrement près des courants de bord Ouest, c'est à dire dans la Rétroflexion des Aiguilles, dans la région du plateau de Campbell, et dans le courant de Brésil-Malouines.
Ces résultats nous ont menés à une analyse circumpolaire de la formation des SAMW, et à une meilleure conception du lien entre la dynamique océanique Australe et la formation des SAMW. La croissance constante des données hydrologiques du programme ARGO dans l'Océan Austral nous a également permis de mieux représenter la répartition des régions de formation des SAMW. Nous avons trouvé que la diffusion tourbillonnaire joue un rôle majeur dans les budgets de chaleur locaux. Au Sud des courants de bord Ouest, et au nord du SAF, la diffusion tourbillonnaire apporte de la chaleur, équilibrant et même dominant les refroidissements hivernaux dus aux flux d'Ekman et aux flux air-mer. Elle réduit en particulier la déstabilisation de la couche de mélange au nord du SAF dans l'Ouest du bassin Indien, en aval de la Rétroflexion des Aiguilles, et dans l'Ouest du bassin Pacifique, en aval du Plateau de Campbell.

Résumé :
This chapter delves into the dark market for juvenile sex work, which to a large extent was a function of Tonkin's extreme poverty. It discusses the multiple social safety nets of Vietnamese society and how despite the availability of such programs, children fall back on sex work for survival. It discusses how colonial authorities tried to regulate juvenile sex work through age restrictions. The chapter explores the operations of the market for adolescent sex workers, including the various ways that girls were recruited to sex work, who their managers were, how these managers kept their operations secret, and which industries served, in part, as fronts for juvenile sex work.

Résumé :
This chapter has built on research on today's modern organizations to lay the foundations for a comprehensive and systematic theorization of enterprise social systems. Theorizing virtuality marks a fundamental transformation in space-time parameters in communications.

Résumé :
This chapter has built on research on today's modern organizations to lay the foundations for a comprehensive and systematic theorization of enterprise social systems. Theorizing virtuality marks a fundamental transformation in space-time parameters in communications. This is especially so in the context of rapid current advancements in IT such as cloud computing, as well as numerous other technological fronts. Current IT trends show that increased spatio-temporal plasticity heightens the effectiveness and the efficiency of modern enterprise social systems. In particular, subject-oriented asynchronous communications experience greater inferred plasticity and event-oriented synchronous communications experience greater referred plasticity. Finally, enterprise social systems vary in their degree of virtuality based on the perspective of the relevant stakeholder group considered.

Résumé :
Mobile Location Based Services (MLBS) have been in operation since the 1970s. Conceived initially for military use, the Global Positioning System technology was later released to the world for other applications. As usage of the technology increased, mobile network points, developed by mobile service operators, supplemented its usage in various applications of MLBS. This chapter charts the trajectory of MLBS applications in the mass market, afforded by the evolution of technology, digital, and mobility cultures. Assimilating various MLBS classifications, it then situates examples into four quadrants according to the measures of user-position or device-position focus, and alert-aware or active-aware applications. The privacy implications of MLBS are captured on the economic, social, and political fronts, and its future is discussed.

Résumé :
Throughout 1943, Allied forces moved forward on all fronts: taking control of the Mediterranean and toppling Mussolini from power in Italy, pushing the Germans back across the broad front in the Soviet Union, and continuing to gain enough ground in the Pacific that American planes were in the position to consistently strike at the Japanese home islands by late in the year. The year also marked the height of the Grand Alliance in terms of cooperation among the Big Three. Roosevelt, Stalin, and Churchill were finally able to meet in November-December 1943 in Teheran to plan for the final victory and discuss peace and the postwar world. Teheran was the most important meeting of the allied leaders during the war, and the vital decisions reached there carried the war forward through 1944 and to victory in 1945.

Résumé :
This paper presents an extension of the Eulerian-Lagrangian Marker and Micro Cell (ELMMC) method, developed to numerically simulate the interaction between clear fluid flow and composite obstacles. The method can simulate both transient and pseudo-steady state problems that involve wave breaking, impact between fluid fronts, and impact between free surfaces and solid or porous boundaries. The newest capability added to the ELMMC method can simulate interaction between fluid fronts and unrestrained solid/porous obstacles. The extension of the ELMMC method is presented here in detail, including the estimation of the hydrodynamic forces induced by the flow on the solid/porous obstacles, the calculation of the final velocity fields, and the computation of the velocity of the solid/porous obstacles. The capabilities of the new method are demonstrated by simulating two representative problems, namely, a solid/porous sphere falling in a reservoir and a single large wave impacting an unrestrained solid/porous structure.

Résumé :
The end of the 20th century has seen some major developments to the business of pipelines worldwide. In North America and Europe the trend has been toward deregulation of the industry. In other markets the trend has been toward the use of fixed transport cost contracts between shippers and the pipeline company. The net effect of these changes is increased competition in the transport of energy with the resulting requirement to provide the lowest cost of transport. At the same time pipelines need to maintain the traditionally high levels of safety and reliability that customers, the public and regulators have been accustomed to. The pipeline industry has responded to the challenge to reduce costs on a number of fronts. These include the areas of contracting, financing, planning, regulation, market development, and technical developments as well as many other areas. This paper will focus on technical developments that have allowed pipeline companies to reduce the cost of moving large volumes of natural gas at high pressures. Progress that the industry has made in the areas of capital cost reduction will be illustrated by an example of high pressure pipeline design. Capital costs will be compared for five system design pressures that all result in the same maximum flow rate. The optimum high-grade steel will be chosen for each pressure. This will also be compared to costs for using Composite Reinforced Line Pipe (CRLP) a new technology for the pipeline industry.

Dans ASME 2008 27th International Conference on Offshore Mechanics and Arctic Engineering. ASMEDC, 2008. http://dx.doi.org/10.1115/omae2008-58022.
Résumé :
The technological evolution in the offshore sector points out a trend towards an increasing use of high strength steels (grade 80ksi and higher), for both pipelines and risers. Pipeline specifications for deepwater offshore fields demand developments in design criteria (i.e. limit state design), welding, installation, and laying technologies. As long as the market goes deeper in offshore exploration and production, the market trend is to use heavier pipes in steel grade X65/X70 and some technological limits from several fronts are faced and more attractive becomes for the market to have a lighter high strength 100ksi seamless steel grade. The joint industrial program (JIP), termed “Seamless 100 ksi weldable” launched by Tenaris in order to address the complex design issues of high strength Q&T seamless pipes for ultra deep water applications has been finalized. The 100ksi steel grade has been achieved in two wall thickness 16 mm and 25 mm. The main results from both phase I devoted to the development and production of seamless pipes with minimum 100ksi and phase II devoted to evaluate the high strength seamless pipe weldability will be addressed in this paper. Main microstructural features promoting the best strength-toughness results obtained from phase I and the results from phase II, where the heat affected zone (HAZ) characterization made using stringent qualifying configuration such as API RP2Z and the promising results after qualifying the girth welds simulating a typical offshore operation and the Engineering Critical Assessment for installation will be addressed. The results from this development are of interest of all oil & gas companies who are facing as an output from the design project analysis the need to have high strength seamless pipes.

Dans ASME Turbo Expo 2017 : Turbomachinery Technical Conference and Exposition. American Society of Mechanical Engineers, 2017. http://dx.doi.org/10.1115/gt2017-63770.
Résumé :
The use of multi-stage centrifugal compressors carries out a leading role in oil and gas process applications. Green operation and market competitiveness require the use of low-cost reliable compression units with high efficiencies and wide operating range. A methodology is presented for the design optimization of multi-stage centrifugal compressors with prediction of the compressor map and estimation of the uncertainty limits. A one-dimensional (1D) design tool has been developed that automatically generates a multi-stage radial compressor satisfying the target machine requirements based on a few input parameters. The compressor performance map is then assessed using the method proposed by Casey-Robinson [1], and the approach developed by Al-Busaidi-Pilidis [2]. The off-design performance method relies on empirical correlations calibrated on the performance maps of many single-stage centrifugal compressors. An uncertainty quantification study on the predicted performance maps was conducted using Monte Carlo method (MCM) and generalized Polynomial Chaos Expansion (gPCE). Finally, the design procedure has been coupled to an in-house optimizer based on evolutionary algorithms. The complete design procedure has been applied to a multi-stage industrial compressor test case. A multi-objective optimization of a multi-stage industrial compressor has been performed targeting maximum compressor efficiency and flow range. The results of the optimization show the existence of optimum compressor architectures and how the Pareto fronts evolve depending on the number of stages and shafts.

Résumé :
The colossal economic transformations and political intrusions had been affecting brutally China and the Soviet Union in the final decades of the twentieth century. Currently, Russia is a gigantic power, struggling to rebuild its economic base in an era of globalization. There are a number of significant difficulties of guaranteeing a stable domestic order due to demographic shifts, economic changes, and institutional weaknesses. On the other hand, the economic rise of China has attracted a great deal of attention and labeled as a success story by the Western world. The current growth of the Chinese economy is of immense importance for the global economy. Both nations are part of the world’s largest and fastest-growing emerging markets—member of the BRIC. Their respective GDPs are growing at an impressive rate by any global standards. Relations between China and Russia have evolved dramatically throughout the twentieth century. However, it would be fair to argue that during the past decade China and Russia have made a number of efforts to strengthen bilateral ties and improve cooperation on a number of economic/political/diplomatic fronts. The People's Republic of China and the Russian Federation maintain exceptionally close and friendly relations, strong geopolitical and regional cooperation, and significant levels of trade. This paper will explore the burgeoning economic and political relationships between the two nations and place the Russian Far East in the context of Russia's bilateral relations with China in order to examine the political, economic, and security significance of the region for both sides.

Dans ASME 2019 Gas Turbine India Conference. American Society of Mechanical Engineers, 2019. http://dx.doi.org/10.1115/gtindia2019-2491.
Résumé :
Abstract Strict emission norms in the last few decades have paved the path for adaptation of new low NoX emission alternatives to power generation and aircraft propulsion. Lean combustion is a very promising and practicable technology for reducing NOX reduction and also have very high fuel efficiency. However, lean combustion technology suffers from inherent combustion instabilities that are manifested under different conditions, most importantly, thermoacoustic instability and lean blowout. Lean blowout occurs when a gas turbine combustor operating close to lean limit, for lowest NoX emission, faces abrupt changes in fuel homogeneity, quality or flow rate. While many work have been done in thermo-acoustic instability and flame propagation in annular combustors, studies in lean blowout in annular combustors are very limited. The lean limit of combustors are not fixed and is dependent on fuel characteristics and operating condition including environmental effects. So accurate online prediction of lean limit is very important to keep the combustors operating safely near lean limit. Recent works have demonstrated that single burner combustors leave out a significant amounts of physics including interaction of flames from different burners prior to blowout. In this work, a stepped down swirl and bluff body stabilized annular combustor in CB configuration (having chamber and burner), is used as experimental test rig having 4 number of identical burners. Video and heat release data are taken at different conditions as lean blowout is approached. Frequent attachment and reattachment of the flames prior to lift off was seen. As lean blowout is approached, inherent subtle differences in the different burners get amplified when flame becomes sufficiently weak and flame symmetry is broken. As air fuel mixture is made gradually leaner, one by one the flames from different burners elongates although remains partially attached to burner. Further lowering the equivalence ratio results in lift off and merging of the flame fronts of different burners. Three pixel averaged color ratios are extracted from still camera RGB images as flame stability indicators which are, red by blue, red by green and blue by green. The parameters show marked change at the point of lift off as well as at the lean blowout point.

Résumé :
In recent years, the rule of law and, especially, its “proper” implementation has become one of the most debated topics in Europe in recent years. The “Big Bang Enlargement” marked the beginning of dilemmas whether the new EU Member States fulfil the necessary rule of law criteria and opened the way for divergent views on how to implement TEU Article 2 values in practice. Furthermore, constant problems and difficulty of the candidate countries to fulfil the necessary rule of law criteria added to the complexity of the problem. In turn, the European institutions have tried to introduce a series of mechanisms and procedures to improve the oversight and make the states follow the rules - starting from the famous Treaty on the European Union (TEU) Article 7, the Rule of Law Mechanism, annual reports on the rule of law and the most recent Conditionality Regulation. The Conditionality Regulation was finally adopted in December 2020 after much discussion and opposition from certain EU Member States. It calls for the suspension of payments, commitments and disbursement of instalments, and a reduction of funding in the cases of general deficiencies with the rule of law. On the other hand, similar provisions were laid out in the February 2020 enlargement negotiation methodology specifying that in the cases of no progress, imbalance of the overall negotiations or regression, the scope and intensity of pre-accession assistance can be adjusted downward thus descaling financial assistance to candidate countries. The similarities between the two mechanisms, one for the Member States, the other for candidate countries shows an increased sharing of experiences and approaches to dealing with possible deficiencies or breaches of the rule of law through economic sanctioning, in order to resolve challenges to the unity of the European union. The Covid-19 pandemic and the crisis it has provoked on many fronts has turned the attention of the Member States (i.e. the Council) away from the long running problematic issues. Consequently, the procedures against Poland and Hungary based on the Rule of Law Mechanism have slowed down or become fully stalled, while certain measures taken up by some European states have created concerns about the limitations of human rights and liberties. This paper, therefore, analyses the efforts the EU is making in protecting the rule of law in its Member States and the candidate countries. It also analyses the new focus of the EU in the financial area where it has started to develop novel mechanisms that would affect one of the most influential EU tools – the funding of member and candidate countries through its structural and enlargement policy. Finally, it attempts to determine and provide conclusions on the efficiency of new instruments with better regulated criteria and timing of activities will be and how much they would affect the EU and its current and future member states.

Résumé :
Solidarity as one of the cornerstone values of the European Union has been once again seated on the red chair and intensively discussed within the European Union and broader. After the economic recession and migrant crisis that marked the last two decades, the outbreak of the COVID-19 pandemic has once again harshly tested the fundamental objectives and values of the European Union and the responsiveness and effectiveness of its governance system on many fronts. In April, 2020 several EU Member States were among the worst affected countries worldwide and this situation soon became similar in their closest neighbourhood. It put a huge pressure on the EU to act faster, while at the same time placing this sui generis community to the test that led to revealing its strengths and weaknesses. As it happened in the previous crises, the Union launched policies and various programmes that were meant to lessen the burden of the Member States and aspiring countries caused by the crises. The objectives of the mentioned soft law instruments that the EU adopted during the COVID-19 crisis has been not only to show that EU law is equipped to react to health and economic crises rapidly but to deliver its support in terms of solidarity to its Member States and its closest neighbours facing the unprecedented health and economic crisis. This article will explore the value and implication of the solidarity principle in times of Covid-19 in its various manifestations. A special focus will be on the financial and material aspects of the EU instruments created to combat the negative consequences of the pandemic and their further impact on shaping the solidarity principle within the EU system. While examining the character and types of these mechanisms a special focus will be placed on those available to Western Balkan countries, whereas Montenegro as the “fast runner” in the EU integration process will be taken as a case study for the purpose of more detailed analyses. One of the major conclusions of the paper will be that although the speed of the EU reactions due to highly complex structure of decision making was not always satisfying for all the actors concerned, the EU once again has shown that it is reliable and that it treats the Western Balkan countries as privileged partners all for the sake of ending pandemic and launching the socio-economic recovery of the Western Balkans. Analytical and comparative methods will be dominantly relied upon throughout the paper. This will allow the authors to draw the main conclusions of the paper and assess the degree of solidarity as well as the effectiveness of the existing EU instruments that are available to Montenegro and aimed at diminishing negative consequences of the crisis.
