Les protéines vitamine K-dépendantes (PVKDs) sont une famille de protéines connues pour leur implication dans la régulation de la coagulation sanguine. Leur activité dépend d’une modification post-traductionnelle, la γ-carboxylation qui est inhibée par la warfarine. Deux PVKDs, les protéines S et Gas6 ont été identifiées comme ligands des récepteurs tyrosine kinase de la famille TAM. L'étude menée chez les souris invalidées pour ces récepteurs suggère une implication des PVKDs dans la neurogenèse. Chez les rongeurs, la neurogenèse assurée par les cellules souches neurales (CSN) persiste à l'âge adulte dans quelques régions cérébrales dont la zone sous-ventriculaire (SVZ). Mon travail de thèse a eu pour objectif majeur de comprendre l'effet des PVKDs sur l'activité des CSN de la SVZ mais aussi l'implication de la protéine Gas6 dans la rétinogenèse. Nos résultats montrent que l'inhibition de la sécrétion des PVKDs par la warfarine stimule la prolifération des CSN. En outre, nous montrons que les récepteurs TAM et leurs ligands sont exprimés par les CSN et dans le LCR, que la protéine S exogène inverse les effets de la warfarine et que l'absence de la protéine Gas6 chez les souris Gas6-/- induit une réduction de la prolifération des CSN. L'ensemble de ces résultats a permis de mettre en évidence l'implication des PVKDs dans la régulation de la prolifération des CSN. La deuxième partie de ce travail montre que les CSN possèdent une activité phagocytaire basale qui est stimulée par la protéine S. La troisième partie de ce travail montre que chez les souris Gas6-/- soumises à une lésion rétinienne, la prolifération cellulaire permettant la réparation de la lésion est moins importante que chez des souris sauvages<br>Vitamin K-dependent protein (VKDPs) is a family of proteins known for their involvement in the regulation of blood coagulation. Their activity depends on post-translational modification, the γ-carboxylation, witch is inhibited by warfarin. Two VKDPs, protein S and Gas6 have been identified as ligands of TAM receptor tyrosine kinase family. The study lead in mice invalidated for these receptors suggests the involvement of VKDPs in neurogenesis. In rodents, neurogenesis provided by neural stem cells (NSC) persists into adulthood in several brain regions including the subventricular zone (SVZ). My thesis had the main objective to understand the effect of VKDPs on NSC activity of the SVZ but also the involvement of Gas6 protein in retinogenesis. Our results show that the inhibition of VKDPs secretion by warfarin stimulates NSC proliferation. In addition, we show that TAM receptors and their ligands are expressed by NSC and in CSF, that exogenous protein S reverses the warfarin effects and that absence of Gas6 protein in Gas6-/ - mice induced a reduction of NSC proliferation. All these results revealed the involvement of VKDPs in the regulation of NSC proliferation. The second part of this work shows that NSC have a basal phagocytosis activity that is stimulated by protein S. The third part of this work shows that Gas6-/- mice subject to a retinal lesion, cell proliferation to repair the damage is less important than in wild mice

Le droit de l’urbanisme s’articule principalement autour de l’acte de construire. Se pose alors la question fondamentale de la nature juridique du droit de construire. Bien qu’attaché au droit de propriété, celui-ci n’en demeure pas moins défini par des règles d’urbanisme, et s’exerce dans les limites des servitudes administratives et contractuelles. Selon la structure foncière sur lequel est envisagé un projet de construction et le mode opérationnel adopté pour ce faire, le droit de construire, quantifié en surface de plancher, peut être modulé, majoré, ou privatisé. Alors que les pouvoirs publics ont engagé depuis une quinzaine d’années une politique en faveur de la densification, ayant donné lieu à d’importantes réformes du code de l’urbanisme, une réflexion de fond s’impose afin de donner davantage de cohérence et de simplicité à un droit initialement conçu comme une police spéciale de l'occupation et de l'utilisation du sol, et qui ne cesse de se complexifier<br>Urban planning law mainly revolves around the action of building. This leads us to fundamentally question the legal nature/ status of the right to build. Even though the right to build is a property one, it is also defined by urban planning regulations and is subject to administrative and contractual limitations of easements. According to the land property structure, the right to build, quantified in floor area, can be modified, increased or privatized.While public authorities have engaged in the last 15 years into policies favoring densification, that resulted in major reforms of the urban planning code, a more in depth reflection remains necessary to bring more coherence and simplicity to the code, that had been initially conceived as a “special police” for land cover and use, and that is growing to become more and more complex

Syftet med uppsatsen är att försöka få en inblick i hur viktigt det anses vara att en nyanställd ”matchar” en organisation i form av personlighet och värderingar, snarare än att denne besitter rätt yrkeskunskaper. Syftet är även att utreda om det finns en existerande organisationskultur på ett industriföretag, samt hur genomgående denna kultur verkar vara. Avslutningsvis har författarna försökt utreda hur nya medarbetare socialiseras in i den undersökta organisationens kultur. Resultaten är baserade på tre gruppintervjuer med operativ personal, intervjuer med två personer från organisationens ledningsgrupp, samt intervjuer med två olika rekryteringsföretag. Resultaten pekar på att en ”match” med organisationen upplevs vara viktig när det gäller grundläggande värderingar, men att olika personligheter uppskattas mer än lika egenskaper hos nyanställda. Resultaten tyder även på att socialiseringsprocessen kan ha en större betydelse för en upplevd samstämmighet med organisationen, än vad en tillämpad P-O- fit vid rekryteringen kan tänkas bidra till.<br>The purpose with this study is to achieve a deeper knowledge and understanding for the perceived importance of using a Person-Organization fit in recruitment. The study also aims to investigate a possible existing organizational culture in an industrial company, and how concistent this culture seems to be throughout the organization. The authors have also tried to gain knowledge on how new employees are indroduced into this culture. The results are based on three group interviews with operational personnel, interviews with two persons from the manegerial group, and interviews with two recruitment firms. The results indicate that a Person-Organization fit is perceived to be important when it comes to some basic values. However, different personalities are more desirable within the investigated organization concerning recruits. Results also indicate that the socialization process, rather than an applied Person-Organization fit, might have a larger significance for a perceived congruence between personal and organizational values.

Full textAbstract:
Appréhender la question de l'insertion paysagère des éoliennes suppose la détermination préalable des objets juridiques étudiés. Sous les hospices de la notion de « patrimoine commun de la nation », éoliennes et paysages apparaissent ainsi comme des sœurs ennemies. Cette conflictualité est consommée lorsque l'article L. 110-1 du Code de l'environnement dispose que la protection des paysages est d'intérêt général autant que l'est la mise en valeur des ressources naturelles. L'antagonisme postulé des deux notions doit cependant être nuancé en ce que le juge administratif tient le rôle d'arbitre dans les conflits nés de ce que les préoccupations paysagères viennent limiter l'implantation des constructions éoliennes. Alors que ce rapport de force s'apprête à gagner le contentieux spécial des installations classées, le contentieux des permis de construire éolien a été le terrain fertile et propice de l'émergence d'une démarche objective orientant l'appréciation qualitative et donc a priori subjective de l'atteinte aux paysages. Le contentieux des permis de construire éolien a également rendu possible le dépassement du contrôle de l'atteinte aux paysages que la doctrine présente classiquement comme un contrôle dissymétrique, par la formalisation d'un contrôle du bilan paysager des constructions éoliennes pouvant symboliser l'armistice de cet affrontement infécond<br>In order to understand the legal bond between wind turbines and landscapes, preliminary elements must be understood. Regarding the legal concept of a « common national heritage », wind turbines and landscapes appear to be two enemy sisters. The conflict emerges when the Environmental Code presents both landscape protection and natural resource development within general interest. The two antagonising notions have to be refined, as the administrative judge appears to be an adjudicator between landscape protection and wind turbine implementation. Whilst the wind turbine landscape sensitivity question is about to integrate the litigation for Classified Installations for the Protection of the Environment, building permits litigation provides the basis for defining an objective method for the subjective definition of damage to the landscape. Using a litigation concerning building permits, a new method of landscape damage assessment has been drafted. Thus, a fine line balancing landscaping can be considered as the end of the war but not necessarily a victory in this meaningless standoff

Par nécessité ou par volonté, on assiste, depuis plusieurs années, à une augmentation du nombre d’autorisations d’urbanisme obtenues conjointement. On parle, dans ce cas, de « cotitularité » entre les différents titulaires d’un permis unique. Ce critère, qui, par principe, se matérialise au regard d’une pluralité de personnes, s’étend également à la pluralité d’unités foncières, support du permis de construire sollicité. Jusqu’à la réforme des autorisations d’urbanisme, issue de l’ordonnance du 8 décembre 2005, le droit de l’urbanisme ne connaissait qu’un terrain, un permis et un demandeur. Toutefois, l’évolution jurisprudentielle a amené le législateur à consacrer la possibilité, pour plusieurs pétitionnaires, d’obtenir un unique permis de construire, sur une ou plusieurs unités foncières. Or, cette cotitularité interroge car, si elle est permise, aucune précision textuelle n’a permis d’encadrer cette opportunité. Pourtant, celle-ci peut, de prime abord, sembler aisée, dans la mesure où il s’agit de la simple possibilité laissée à une pluralité de maîtres d’ouvrage, d’obtenir ensemble une seule et unique autorisation d’urbanisme. Or, il n’en est rien : sa complexité est manifeste, au regard de l’emprise et de la composition du projet ou encore des incidences relatives à la solidarité existante entre eux durant toute la vie de l’autorisation de construire. Dès lors, le lien de dépendance et de solidarité, issue de l’acte administratif individuel, doit être strictement délimité et encadré par une convention de partenariat de droit privé, qui aura pour objectif d’organiser leurs relations, sans pour autant que l’administration reconnaisse l’existence de celle-ci<br>For several years, we’re attending, by necessity or by willingness, an increase of the number of town-plannings approvals jointly obtained. We are talking, in this case, of « joint holders » between the different holders of an unique permit. This criteria, which on principle, materializes regarding a plurality of people, also extends to the land’s units plurality, support for the requested building permit. Until the reform of urban planning authorizations stem from the order of the 8th of December 2005, the planning law only included a building land, a building permit and an applicant. However, case-law development has led the legislator to devote the possibility for several petitioners to obtain an unique building permit, on one or on plenty of land units. Yet, this « joint holders » interrogates because if its allowed, none textual accuracy allowed to frame this opportunity. However, this one, at first sight, can seem easy ; in so far as it concerned a simple possibility left to a plurality of project owners, to get together one urban planning permit, whose quality-assesment procedures can be various. Unfortunately, it’s not the case, because its complexity is obvious, as long as to the right of way and the project set-up, that relatives implications of the existing solidarity between them throughout the life of the building permit’s authorization, bearing division or not. Consequently, the link of dependency and solidarity, stem from the individual administrative act, must be strictly defined and surrounded by a private’s law partnership agreement whose purpose will be to organize their relationship, without the administration recognizes the existence of this one

Full textAbstract:
As information technologies are adopted by more people to accomplish a greater variety of tasks, the need for optical telecommunication networks with higher capacity and flexibility grows. In addition to improving throughput by increasing transmission rates and the number of wavelength channels, novel network architectures using optical burst or packet based switching are investigated because they allow a more efficient use of transmission capacity and they enable the reorganisation of wavelength connections according to traffic demands. The implementation of such networks requires fast, broadband, transparent, and scalable optical space switches. Although research on optical space switches has been on going for decades, no solution that meets all of the above requirements has been reported yet. The work presented in this thesis introduces a novel optical space switch configuration based on tuneable integrated Fabry-Perot filters working at oblique incidence and investigates their performance. A design method to implement this new switch concept is described and demonstrated with the fabrication and characterisation of optical prototypes. The prototypes are implemented in GaAs/AlGaAs planar waveguides and they are designed to be operated using the electro-optic effect. Deep etching is used to create the switch features and a comprehensive optimization of the waveguide structure is conducted to minimize radiation losses. To maximize the number of wavelength channels that can be controlled with a small refractive index modulation, the switches have a 200 GHz comb frequency response that transmits/reflects one out of every two channels on the ITU 100 GHz grid. Thus, shifting their frequency response by one channel spacing is sufficient to change the state of every channel. Furthermore, four Fabry-Perot cavities are coupled to obtain a flat and wide theoretical passband of more than 50 GHz. A Gaussian beam p<br>Alors que de plus en plus de gens utilisent les technologies de l'information pour accomplir une variété croissante de tâches, le besoin pour des réseaux de télécommunication optique plus flexibles et de plus grande capacité est grandissant. En plus d'augmenter la vitesse de transmission et le nombre de canaux disponibles, de nouvelles architectures utilisant la commutation optique par rafale ou par paquet sont en développement puisqu'elles permettent une utilisation plus efficace de la capacité de transmission et qu'elles rendent possible la réorganisation du réseau en fonction des variations des demandes de service. L'implémentation de tels réseaux nécessite des commutateurs optiques rapides, transparents, à large bande et extensibles. Bien que la recherche sur les commutateurs optiques est cours depuis des décennies, aucune des solutions proposées jusqu'à maintenant ne possède toutes ces qualités. Le travail présenté dans cette thèse décrit une nouvelle configuration de commutateurs optiques utilisant des filtres Fabry-Perot intégrés et accordables qui fonctionnent à incidence oblique et explore leur performance.L'approche utilisée pour concevoir ce nouveau commutateur est expliquée et démontrée par la fabrication et la caractérisation de prototypes optiques. Ces prototypes sont construits dans un guide d'onde planaire en arsenic de gallium et ils sont conçus pour être opérés à l'aide des effets électro-optiques. De profondes gravures sont utilisées pour créer les composantes du commutateur et une étude sur l'optimisation de la structure du guide d'onde est faite dans le but de minimiser les pertes par radiation. Afin de maximiser le nombre de canaux opérables avec une faible modulation de l'indice de réfraction, les commutateurs possèdent une réponse en peigne espacée de 200 GHz qui transmet/réfléchit un canal sur deux de la grille de 100 GHz de l'ITU.$

Full textAbstract:
Business Permit System is known as an inefficient system because it is purely bureaucratic and the transactions take an inordinate amount of time to complete. Currently, there is a 3 week minimum time frame which is causing losses to both traders and citizens. It takes at least one week of tracking for every office and then approximately one month in order to get the permit. In fact, this system in Saudi Arabia is considered to be quite a primitive bureaucratic system that has not been changed for decades. The current business permit system is outdated and wastes both money and precious time. Many trips to various government offices are now required to follow the permit through its application process. Business' headquarters are usually located in the main cities. These headquarter offices send their delegates to follow-up their permit procedures which are located in small cities. They pay unnecessary additional expenses for their representatives such as hotel, transportation, and food costs. The system also increases the number of commuters to the city. Traffic jams, car accidents and even deaths may be the unintended consequences. The customers waste copious amounts of fuel and time tracking the pennit applications, while the Government spends millions of Saudi riyals in a fuel anti-consumption program. From the above we could say the current permit system contributes to delaying the citizen and increasing his costs. By using ever increasing amounts of gasoline, the Saudi economy and environment are harmed in many ways. Also, the system contributes to the transportation issues The inspectors have a serious issue with the current system. While they are inspecting the business site, they waste a lot of time by driving long distances. They waste time by driving from the office to the business site and from the business site to other business site in order to inspect them. This affects the inspector's health and shortens the life of the car which used by the inspectors. Also, that leads to increased car expenses such as fuel, car oil and maintenance.

Full textAbstract:
Widespread basaltic volcanism occurred in the region of the West Siberian Basin (WSB) and the Taimyr Peninsula in central Russia, and voluminous A-type magmatism within the Mongolian-Transbaikalian belt in southeast Siberia, during Permo-Triassic times. New 40Ar/39Ar age determinations on plagioclase grains from deep boreholes in the WSB reveal that the basalts were erupted at ~250 million years ago. This is synchronous with the main period of the Siberian Traps volcanism, which was located farther east. The age and geochemical data presented confirm that the WSB basalts are part of the Siberian Traps, and at least double the confirmed area of the volcanic province as a whole. The larger area of volcanism strengthens the link between the volcanism and the end-Permian mass extinction. Furthermore, it is argued that the WSB and Taimyr basalts are genetically related to the Siberian Traps basalts, especially the Nadezhdinsky Suite found at Noril’sk. This suite immediately preceded the main pulse of volcanism that extruded lava over large areas of the Siberian Craton. Magma volume and timing constraints strongly suggest that a mantle plume was involved in the formation of the Earth’s largest continental flood basalt province. The Mongolian-Transbaikalian granitoid belt covers over 600,000 km2 with over 350 single A-type plutons. New U-Pb geochronological data presented here demonstrate that no plutonic complex dated is 250 Ma old. Although mantle-derived material played a prominent role in the granitoid generation, these melts may have been generated by processes other than decompressional melting within the head of a mantle plume. The new U-Pb ages and other observations contradict the idea of a relation between the Siberian plume and magmatic activity in the territory of Transbaikalia. An alternative preferred model inducing up rise of asthenospheric material includes slab break-off after a long period of subduction.

Full textAbstract:
The Canadian supply management system offers some lessons for the design of a domestic permit trading system. One of the objectives of the domestic trading system is minimizing costs and maximizing the system's efficiency for participants and system administrators. This paper suggests that a permit trading system designed with a longer permit period and without a grace period can be more efficient than a system designed with a shorter permit period and a grace period for compliance. This study is based on Canadian Supply Management System experience and examines the Canadian dairy industry, where two different schemes (monthly and annual) have been used. Under the annual scheme, a strong compliance mechanism stimulates participants to exchange quotas during the dairy year (permit period) and does not require burdensome, non-compliance procedures after the permit period ends. The monthly scheme is characterized by a short permit period and a grace period for compliance. This study examines how these two schemes affect participants' behavior on the quota exchange. The empirical results show evidence of the influence of different schemes on farmers' behaviours regarding the quota exchange. As a conclusion, the paper recommends the use of a permit trading mechanism with a longer permit period and without a grace period for the design of a carbon trading system. The results support Barichello (2002), who developed the Canadian domestic permit trading scheme on the basis of receiving an offset from agricultural soil carbon sinks.

När man ska bygga något nytt, ändra en byggnad eller riva en byggnad behövs ett bygglov från kommunen där åtgärden ska utföras. Örebro kommun har sett att majoriteten av enklare bygglovsärenden behöver kompletteras innan de kan beviljas. Detta medför en förlängd bygglovsprocess i väntan på en komplett bygglovsansökan. Syftet med denna rapport är att undersöka de underliggande faktorerna som medför att personer som söker bygglov inte skickar in kompletta bygglovshandlingar samt att hitta lösningar på dessa. En enkätundersökning har genomförts för att undersöka vad bygglovssökare i Örebro kommun upplevde var bra respektive dåligt med deras ärende och bygglovsprocess. Det genomfördes även en granskning på kommunens hemsida för bygglov i syfte att försöka förbättra den och hitta faktorer som leder till att bygglovssökare inte skickar in kompletta handlingar. Denna rapport avgränsar sig till privatpersoner som fått komplettera sin bygglovsansökan innan de fått ett beviljat bygglov mellan sommaren 2018 och våren 2019 i Örebro kommun. Bygglovstyperna som undersökts är nybyggnad av komplementbyggnad, tillbyggnad av komplementbyggnad samt tillbyggnad av enbostadshus. Resultat visar att kontrollplanen som är nödvändig för en ansökan ofta är bristfällig jämfört med andra handlingar. De som sökt bygglov menar att den är svår att förstå och information om kontrollplanen som hittas på Örebro kommuns hemsida inte är tillräckligt tydlig. Det visar sig också att hälften av respondenterna i enkäten som gjorts är positivt inställda till en kort informationsfilm på Örebro kommuns hemsida där det förklaras vad som ska skickas in samt hur handlingarna ska se ut. Kontrollplanen visade sig vara problematisk för personer som sökt bygglov. De tyckte att det fanns en osäkerhet gällande om den skulle skickas med, vad för punkter som ska finnas med i kontrollplanen för respektive ansökan samt vad punkterna man kontrollerar mot betyder. En åtgärd som kan förbättra detta problem är att tydligt på Örebro kommuns hemsida informera att en kontrollplan måste skickas in med en ansökan samt vad för konsekvenser en ej komplett ansökan får. Konsekvensen är en förlängd bygglovsprocess i väntan på en komplett bygglovsansökan. Man kan också på Örebro kommuns hemsida tydligt förklara vad varje kontrollpunkt i kontrollplanen som ska med betyder. Det Örebro kommun också kan tänka på är att minska mängden text som finns på bygglovssidorna. Detta för att personer som söker bygglov ska se en kort och koncist förklaring på vad för handlingar som ska skickas in för att underlätta för dem. Örebro kommun bör också visa exempel på kontrollplaner i exempelritningar som finns på Örebro kommuns hemsida för att sökande på ett enkelt sätt ska kunna se vilka handlingar som ska skickas in.<br>When you want to build something new, reconstruct a building or demolish a building, a building permit is needed from the municipality. Örebro municipality has seen that a majority of building permit cases needs to be supplemented before they can be approved. This results in an extended building permit process. The purpose of this report is to examine the underlying factors that leads to people seeking building permits do not submit complete. A survey has been carried out to investigate what people applying for building permits in Örebro municipality experienced was good and bad with their case regarding the building permit process. An inspection was also carried out on the municipality's website for building permits to find reasons why people applying for building permits do not submit complete documents. This report is limited to individuals who have supplemented their building permit application before receiving a granted building permit between summer 2018 and spring 2019 in Örebro municipality. The building permits that were investigated are of simpler cases. Results show that the control plan is often inadequate compared to other documents. Those who have applied for a building permit mean that it is difficult to understand the information in the control plan found on the Örebro municipality's website and that the information is not sufficiently clear. It also turns out that half of the respondents in the survey have been positively set towards a short information film on the Örebro municipality's website. The information film would explain what type of documents that should be submitted and how the documents should look. The control plan proved to be problematic for people who applied for a building permit. They felt that there was an uncertainty regarding the control plan whether it should be sent in with the apply for building permits. They also felt an uncertainty regarding what type of control points should be included in the control plan for each application and what the controls you check against means. An action that can solve this problem is to clearly inform on Örebro municipality's website that a control plan must be submitted with an application and what consequence a non-complete application results in. The consequence is an extended building permit process pending a complete building permit application. Örebro can also clearly explain on their website what each control point in the control plan means. What the Örebro municipality also can think about is to reduce the amount of text that is on the building permit webpages. This is because people who apply for a building permit should see a brief and concise explanation of what documents should be submitted in order to facilitate them. Örebro municipality should also have examples of control plans in the example documents that are available on the website, in order for applicants to easily see which documents that should be submitted.

Depuis l’amendement du Clean Air Act (1990), les marchés d’échange depermis d’émissions connaissent un succès grandissant. Un aspect peu étudié de leurfonctionnement est la participation des citoyens pour acheter et retirer des permisd’émissions. Cette thèse vise à étudier l’opportunité d’ouvrir le marché de permis auxcitoyens et à analyser les implications de leur participation. Dans un premier chapitre, nousrevenons sur le débat taxe versus marché. Nous montrons que lorsque le plafond depollution est strictement supérieur au plafond de pollution optimal, la participation descitoyens est socialement bénéfique et n’est jamais socialement dommageable, même enprésence de comportement de passager clandestin. Dans le deuxième chapitre, à partird’exemples de marchés mis en place aux États-Unis et en Europe, nous mettons enévidence l’émergence d’une demande de retrait de permis de la part des citoyens et desONG environnementales. Dans le troisième chapitre, nous montrons qu’il est possible delutter efficacement contre le problème de passager clandestin en subventionnant lademande de retrait de permis des citoyens. Par ailleurs, l’intervention d’une éthique baséesur un postulat de liberté et de souveraineté conduit à recommander l’autorisation descitoyens à participer au marché. Enfin, le dernier chapitre analyse la participation descitoyens dans le cadre d’un modèle de pollution régionale et apprécie leur implication selonla valeur des paramètres des coefficients de transferts de pollution<br>Since the Clean Air Act Amendment (1990), the markets of tradable emissionpermits are becoming increasingly attractive. Very few works on the functioning of thesemarkets have analyzed the participation of citizens in order to buy and retire emissionspermits. This dissertation aims to study the effects of allowing citizens to participate inmarkets of tradable emission permits. In the first chapter, we show that when the pollutioncap is strictly greater than the optimal one, citizen’s participation is socially beneficial andnever socially harmful, even in the presence of free-riding. In the second chapter, based onoperating pollution markets in the US and Europe, we highlight the emergence of a demandto purchase and cancel emissions permits. In the third chapter, we show how it is possible topartly solve the free rider problem by subsidizing the citizen’s demand. Moreover, we arguethat an ethics based on the freedom and the sovereignty of citizens commands to allowcitizens participation in pollution market. In the fourth chapter, we focus on citizen’sparticipation in pollution markets with a regional pollution model. Such an implicationdepends on the value of transfer coefficients

Full textAbstract:
Les risques naturels majeurs constituent une menace plus ou moins récurrente pour la plupart des populations de la planète. Les catastrophes naturelles sont à la fois sources et révélatrices d’inégalités sociales et environnementales, dans le monde, mais aussi sur le territoire de la République française. Les Antilles françaises sont très fréquemment, et très lourdement frappées par les aléas naturels. La réponse en matière de gestion des crises, et, en amont, en matière de prévention, ne nous semble pas à la hauteur des défis, et des besoins des populations. C’est la raison pour laquelle nous nous interrogeons, à travers la présente thèse, sur la place de la solidarité et de l’égalité, dans le régime juridique des risques naturels majeurs. C’est une préoccupation doctrinale majeure, inscrite dans la constitution. La recherche du lien entre droit des risques naturels majeurs et justice sociale et environnementale est l’objet de la présente étude, s’agissant de la réponse juridique à la préoccupation des populations et catégories défavorisées, qui s’avèrent a priori les plus atteintes par les catastrophes naturelles. Les limites des textes, l’insuffisance des moyens, ainsi que les pratiques locales, facteurs d’aggravation des vulnérabilités, le laxisme des pouvoirs publics nationaux et territoriaux, l’absence de culture de risque et l’esprit « kokagneur » des populations (avec des différences de comportement entre la Guadeloupe et la Martinique), toutes ces considérations rendent illusoire la détermination proclamée des pouvoirs publics de résoudre les problèmes de risques naturels majeurs. Des voies d’un renforcement de la solidarité sont proposées. Cette contribution à la recherche sur les risques ambitionne d’apporter aux acteurs, une vision transversale de la problématique des risques naturels, par l’analyse du régime juridique confronté à une exigence de justice sociale et environnementale. Les Antilles françaises servent de support à cette étude<br>Major natural hazards are more or less recurring threat for most people in the world. Natural disasters are both sources and revealing social and environmental inequalities in the world, but also in the French Republic. The French West Indies are very frequently and strongly hit by natural hazards. The answer in terms of crisis management, and beforehand, in terms of prevention, doesn’t seem to be up to the population’s challenges and needs. This is why we wonder, in this thesis, about the place of solidarity and equality in the legal system of major natural hazards. This is a major doctrinal concern in the constitution. The research of the relationship between major natural hazards law and environmental and social justice is the subject of this study, concerning the legal answer to the concerns of the underprivileged people and categories, which prove to be a priori the most struck by natural disasters. The limits of the legislation, inadequate resources and local practices, vulnerabilities worsening factor, the laxity of the national and territorial public authorities, the lack of risk culture and the "kokagneur" spirit of the populations (with behavior differences between Guadeloupe and Martinique), all these considerations make unreal the government’s proclaimed determination to solve the major natural hazards issues. Ways to strengthen solidarity are proposed. This contribution to risks research aims to bring to the players an interdisciplinary view of natural hazards issues, through the analysis of the legal system confronted with the requirement of social and environmental justice. The French West Indies are used as research support

Full textAbstract:
Lo scopo di questo lavoro di tesi è stato quello di studiare il comportamento di un fascio laser interagente con un risonatore ottico, grazie al quale il laser può essere stabilizzato agganciando la sua frequenza di missione ad uno dei modi della cavità. In sintesi la lunghezza d’onda del fascio è vincolata ad assumere valori multipli della lunghezza della cavità, dato che in questo modo si possono decisamente migliorare le caratteristiche spettrali di un laser tipico. La stabilizzazione, e il restringimento di riga del laser, vengono effettuati agganciando la sua frequenza sul modo trasverso fondamentale tramite un sistema di feedback. La cavità è però soggetta a sua volta a fluttuazioni di tipo termico e meccanico. Una variazione in lunghezza del risonatore comporta una variazione in frequenza dei modi.
Le derive di frequenza dovute agli effetti termici si possono limitare utilizzando materiali con bassa dilatazione termica posti in ambienti la cui temperatura viene stabilizzata tramite un sistema di feedback. Per le vibrazioni, invece, il lavoro è più complicato: non essendo sufficiente mettere il sistema in ambienti isolati per attenuare le fluttuazioni, è stato recentemente proposto di studiare la posizione migliore dei sostegni affinché le fluttuazioni, e quindi le conseguenti variazioni in lunghezza della cavità, risultino minime. Per analizzare questo problema è stato utilizzato un software open-source per l’analisi agli elementi finiti, Salome-Meca, tramite il quale è stata riprodotta la geometria del un risonatore ottico a nostra disposizione, per simularne il comportamento sotto l’effetto del campo gravitazionale. Da qui si sono ottenuti i dati riguardo lo spostamento degli specchi della cavità in funzione della posizione del sostegno, dai quali si è riuscito a trovare il punto di posizionamento del supporto capace di ridurre lo spostamento di un ordine di grandezza.

Full textAbstract:
A seqüência Permo-Pensilvaniana da Bacia do Parnaíba foi estudada em afloramentos, perfis radioativos e testemunhos de sondagens, para elaboração de um arcabouço crono-estratográfico. A etapa inicial do trabalho consistiu de uma revisão bibliográfica sobre a litoestratigrafia e os ambientes deposicionais do Paleozóico da Bacia do Parnaíba, enfatizando-se as rochas depositadas no Pensilvaniano e Permiano, bem como de uma revisão conceitual sobre a Estratigrafia de Seqüências e bacias evaporíticas, abordando-se a aplicação desses conceitos aos vários modelos de bacias evaporítica, especialmente aqueles relacionadas ao contexto intracratônico. Na segunda etapa do trabalho foram descritos afloramentos e testemunhos de sondagens, e identificados padrões de empilhamento em perfis radioativos, todos utilizados na elaboração de seções colunares. A partir das seções levantadas foi possível identificar superfícies-chaves, associações litofaciológicas e tratos de sistemas. A distribuição das unidades aloestratigráficas e litoestratigráficas foi ilustrada em seções estratigráficas. Foram propostas modificações nos limites das Formações Pedra de Fogo e Motuca. Na terceira etapa foram analisados dados e discutidos os resultados. Os trabalhos foram desenvolvidos segundo duas abordagens: uma para a borda leste, essencialmente siliciclástica e outra referente a porção interior da bacia, num contexto evaporítico. Na borda leste foram utilizadas seções colunares de afloramentos e dados de subsuperfícies para elaboração de uma seção estratigráfica ao longo de mais de 260 km, envolvendo essencialmente siliciclásticos com idade de deposição restrita ao Pensilvaniano. Foram então identificadas cinco seqüências de terceira ordem e seus respectivos tratos de sistemas. Foi também sugerida a presença de prováveis vales incisos entre a seção colunar da Serra da Cruz e a localidade do poço 9. A outra abordagem, restrita a avaliação de dados de subsuperfície, permitiu a proposta de um modelo alternativo de bacia evaporítica para a Seqüência Permo-Pensilvaniana da Bacia do Parnaíba. A partir da identificação de superfícies chaves e do uso do Gráfico de Fischer, foram elaboradas duas seções estratigráficas que, a grosso modo, correspondem ao Pensilvaniano e ao Permiano. Na seqüência Pensilvaniana (2ª ordem) foram identificadas seis seqüências de 3ª ordem, com pelo menos duas correspondendo a seqüências compostas. Na porção mais central da bacia elas ocorrem com espessura e aparentemente sem hiatos significativos. Em direção as bordas da bacia, as espessuras das seqüências tendem a diminuir. Para os estratos permianos também foram identificadas seis seqüências de 3ª ordem. Estas seqüências apresentam pouca variação de espessura e geometria tabular.<br>The Permian-Pennsylvanian sequence of the Parnaíba Basin was investigated through outcrops, gamma-ray profiles and core sampling, in order to establish its chronostratigraphic frameworks base on Sequence Stratigraphy concepts. The initial part of the study involved a bibliographical reappraisal of the Paleozoic depositional environments of the Parnaíba Basin, emphasizing the Permian-Pennsylvanian sequence. This was followed by a conceptual review on Sequence Stratigraphy and evaporate basins, with application of these principles to intracratonic basins. The litoestratigraphy of the Piauí, Pedra de Fogo and Motuca formations were re-evaluated and some modifications were proposed for the boundaries of the latter ones. Description of outcrops and drill cores, together with the identification of cyclic stacking patterns in gamma-ray profiles, were employed to work out columnar sections in the second part of the research. Based upon these sections, it was possible to identify key-surfaces, lithofaciological associations and system tracts. The distribution of the allostratigraphic and lithostratigraphic units was depicted in stratigraphic sections. The third part of the work involved data analysis and discussion of the results. In the eastern border of the basin, outcrop-based columnar sections and subsurface data were used to build a stratigraphic section of the Pennsylvanian siliciclastic rocks, which run along more than 260 km; five 3rd order sequences and the corresponding system tracts were then identified. The occurrence of probable incised-valley systems is also suggested between the Serra da Cruz columnar section and borehole 9 locality. Furthermore, subsurface data related to the main evaporate basin. The identification of key-surfaces and the Fischer plot technique allowed compilation of two stratigraphic sections roughly corresponding to the Pennsylvanian-Permian time span. In the 2nd order Pennsylvanian sequence, two 3rd order sequences were identified and six 4rd order sequence; at least two of them correspond to composite sequences. In the central portion of the basin, the above mentioned sequences are thicker and apparently devoid of significant hiatus. These sequences are thinner near the basin borders. Five or seven 4rd order sequences were also identified in the Permian age interval, displaying a sheet-like geometry with minor thickness variations.

Fiber-optic Fabry-Perot interferometric (FFPI) sensors have been widely used due to their high sensitivity, ease of fabrication, miniature size, and capability for multiplexing. However, direct measurement of self-assembled thin films, receptor immobilization process or biological reaction is limited in the FFPI technique due to the difficulty of forming Fabry-Perot cavities by the thin film itself. Novel methods are needed to provide an accurate and reliable measurement for monitoring the thin-film growth in the nanometer range and under various conditions.
In this work, two types of fiber-optic multicavity Fabry-Perot interferometric (MFPI) sensors with built-in temperature compensation were designed and fabricated for thin-film measurement, with applications in chemical and biological sensing. Both the tubing-based MFPI sensor and microgap MFPI sensor provide simple, yet high performance solutions for thin-film sensing. The temperature dependence of the sensing cavity is compensated by extracting the temperature information from a second multiplexed cavity. This provides the opportunity to examine the thin-film characteristics under different environment temperatures.
To demonstrate the potential of this structure for practical applications, immunosensors were fabricated and tested using these structures. Self-assembled polyelectrolytes served as a precursor film for immobilization of antibodies to ensure they retain their biological activity. This not only provides a convenient method for protein immobilization but also presents the possibility of increasing the binding capacity and sensitivity by incorporating multilayers of antibodies into polyelectrolyte layers. The steady-state measurement demonstrated the surface concentration and binding ratio of the immunoreaction. Analysis of the kinetic binding profile provided a fast and effective way to measure antigen concentration. Monitoring the immunoreaction between commercially available immunoglobulin G (IgG) and anti-IgG demonstrated the feasibility of using the MFPI sensing system for immunosensing applications.<br>Ph.

Analysis of this project was completed using results from pre- and post-outreach experience questionnaires as a way to establish demographic information of the participants, get comparative awareness and interest of college and science information, and find some common points to make connections between the groups of students. Questionnaires were also used for the classroom teachers to understand how outreach benefited their classroom. Journals were utilized with college students as well as wrap-up meetings after each outreach experience in order to document personal experiences both as a mentor as well as students growing in their own content mastery. I also kept notes of the experience from my viewpoint.

Full textAbstract:
The most desirable characteristic of a facility layout is its ability to maintain its efficiency over time while coping with the uncertainty in product demand. A traditional facility layout design method is governed by the flow intensity between departments, which is the product flow quantity between two departments. Hence, an error in the product demand assessment can render the layout inefficient with respect to material handling costs. Most of this research integrates uncertainty in the form of probability of occurrence of different from-to charts. In an environment where the variability of each product demand is independent, the derivation of “probabilistic from-to chart” based scenarios cannot be used to address uncertainty of individual demands. This dissertation presents a facility layout problem approach to deal with the uncertainty of each product demand in the design of facility layout. Two procedures are presented: the first procedure is utilized to assess the risk associated with the layout, while the second procedure is used to develop the layout that minimizes risk. Results from case studies have shown that the procedure results in reduction of risk by as much as 68 percent.<br>Thesis (Ph.D.) - Wichita State University, College of Engineering, Dept. of Industrial and Mechanical Engineering

This dissertation presents various aspects of the solution of the linear multi-period stochastic programming problem. Under relatively mild assumptions on the structure of the random variables present in the problem, the value function at every time stage is shown to be jointly convex in the history of the process, namely the random variables observed so far as well as the decisions taken up to that point.
Convexity enables the construction of both upper and lower bounds on the value of the entire problem by suitable discretization of the random variables. These bounds are developed in Chapter 2, where it is also demonstrated how the bounds can be made arbitrarily sharp if the discretizations are chosen sufficiently fine. The chapter emphasizes computability of the bounds, but does not concern itself with finding the discretizations themselves.
The practise commonly followed to obtain a discretization of a random variable is to partition its support, usually into rectangular subsets. In order to apply the bounds of Chapter 2, one needs to determine the probability mass and weighted centroid for each element of the partition. This is a hard problem in itself, since in the continuous case it amounts to a multi-dimensional integration. Chapter 3 describes some Monte-Carlo techniques which can be used for normal distributions. These methods require random sampling, and the two main issues addressed are efficiency and accuracy. It turns out that the optimal method to use depends somewhat on the probability mass of the set in question.
Having obtained a suitable discretization, one can then solve the resulting large scale linear program which approximates the original problem. Its constraint matrix is highly structured, and Chapter 4 describes one algorithm which attempts to utilize this structure.
The algorithm uses the Dantzig-Wolfe decomposition principle, nesting decomposition
levels one inside the other. Many of the subproblems generated in the course of this decomposition share the same constraint matrices and can thus be solved simultaneously. Numerical results show that the algorithm may out-perform a linear programming package on some simple problems.
Chapter 5, finally, combines all these ideas and applies them to a problem in forest management. Here it is required to find logging levels in each of several time periods to maximize the expected revenue, computed as the volume cut times an appropriate discount factor. Uncertainty enters into the model in the form of the risk of forest fires and other environmental hazards, which may destroy a fraction of the existing forest. Several discretizations are used to formulate both upper and lower bound approximations to the original problem.<br>Business, Sauder School of<br>Graduate

While over-dispersed Poisson age-period-cohort and extended chain-ladder models are used in a number of fields, so far no rigorous statistical theory has been available. We consider models for aggregate data organized in a two-way table with age and cohort as indices, but without measures of exposure. In these models, used for example in actuarial science, demography, economics, epidemiology and sociology, the number of parameters grows with the number of observations. Thus, standard asymptotic theory is invalid. In Chapter 2, we propose a repetitive structure that keeps the dimension of the table fixed while increasing the latent exposure. We pair this with the assumptions of infinitely divisible distributions which include a variety of compound Poisson models and Poisson mixture models. We then show that Poisson quasi-likelihood estimation results in asymptotic t parameter distributions, F inference, and t forecast distributions. In Chapter 3, we build on the asymptotic framework from Chapter 2 and develop tests for model specification. The over-dispersed Poisson model assumes that the over-dispersion is common across the data. A further assumption is that effects do not have breaks, for example age effects do not vary over cohorts. A log-normal age-period-cohort model makes similar assumptions. We show that these assumptions can easily be tested and that similar tests can be used in both models. In Chapter 4, we develop a non-nested test that allows one to evaluate whether the over-dispersed Poisson or log-normal model is the better choice for the data. While the over-dispersed Poisson model imposes a fixed variance to mean ratio, the log-normal models assumes the same for the standard deviation to mean ratio. We leverage this insight to propose a test that has high power to distinguish between the two models. Again, the theory is asymptotic but does not build on a large size of the array and instead makes use of information accumulating within the cells.

The use of expert knowledge in our specialized societies is constantly rising in all kinds of human activities. The same situation is observed in trials, where more and more judicial decisions are making based on expert evidence. There are two main categories of expert evidence: one of them developed by an expert hired by a party according with his interests, the other one performed by a court appointed expert. Among their differences are the ones that the party’s expert is per-se the expert chosen by one of the sides, carries on the pertinent tests without a procedure control, presenting to the judge statements over the facts that he has to value. On the other side, the court appointed expert is named by the judge, carries out the tests under the procedure frame and, for this, is susceptible to the procedure control, amen to the existence of a possibility that the judge specifies the epistemic necessities of the case. Once their differences are identify is necessary to reflect them in the admissibility, hearing and assessment of each category of expert evidence<br>En nuestras sociedades actuales, cada vez más especializadas, el uso del conocimiento experto es una constante en prácticamente todas las actividades del ser humano.

Hay dos categorías de pruebas periciales: una desarrollada por un perito de parte, seleccionado por ésta en función de sus intereses, y otra realizada por un perito oficial, que es de alguna manera seleccionado por el juez.

Communications over social media, telephone, email, text etc have emerged as an integral part of modern society and they are popularly used for the expression of anger, anxiety, fear, agitation and opinion by the people. People's social interaction tend to increase dramatically during periods of epidemics, protest and calamities. Therefore, above mentioned communication channels plays an important role in the spread of infectious phenomenon, like rumors, fads and effects. These infectious phenomena alters people's behavior during disease epidemic [1][2].
Social contact networks and epidemics co-evolve [1][2]. The spread of a disease influences people's behavior which in turn changes their social contact network, thereby altering the disease spread itself. As a result, there is a need for modeling the spread of these infectious phenomena that lead to changes in behavior. Their propagation among population primarily depends on the social contact network. The nature of social contagion spread is very similar to the spread of any infectious disease as they are contagious in nature. To spread contagious disease requires direct exposure to an infectious agent, whereas social contagions can be spread using various communications media like social networking forums, phones, emails and tweets.
EpiSimdemics is an individual-based modeling environment. It uses a people-location bipartite graph as the underlying network [3]. In its current form, EpiSimdemics requires two people to interact at a location to model simulations. Thus, it cannot simulate the spread of social contagions that do not necessarily require the meeting of two agents at a location.
We enhance EpiSimdemics by incorporating Person-Person network, which can model communications between people that are not contact based such as communications over email, phone, text and tweet. This Person-Person network is used to model effects (social contagion) which induce behavioral changes in population and thus impacting the disease spread. The disease spread is modeled on Person-Location network. This leads to the scenario of two interacting networks: Person-Person network modeling social contagion and Person-Location modeling disease. Theoretically, there can be multiple such networks modeling various interacting phenomena.
We demonstrate the usefulness of this network by modeling and simulating two interacting PTTSs (probabilistic timed transition systems). To model disease epidemics, we have defined Disease Model and to model effects (social contagion), we have defined Fear Model. We show how these models influence each other by performing simulations on EpiSimdemics with interacting Disease and Fear Model. Therefore a model that does not include the affect adaptations on disease epidemics and vice-versa, fails to reflect the actual behavior of a society during disease epidemic spread. The addition of Person-Person network to EpiSimdemics will allow for a better understanding of the affect adaptions, which can include behavior changes in society during an epidemic outbreak. This would lead to effective interventions and help to better understand the dynamics of disease epidemic.<br>Master of Science
