Abstract:
La prospective démographique localisée est susceptible de recouvrir plusieurs démarches distinctes. Cette diversité méthodologique renvoie à la fois à des différences de degré d’élaboration et de respect des exigences de cohérence interne et au contexte qui a conduit à projeter une ou plusieurs populations locales. Après avoir présenté les principales méthodes de projection démographique utilisées en démographie locale, ce texte explique et illustre, par un exemple caractéristique, la façon dont elles peuvent être articulées pour répondre aux demandes de plus en plus composites des collectivités territoriales. Il décrit ensuite les données de recensement nécessaires à la mise en oeuvre de ces démarches de prospective démographique localisée en fonction de leur degré d’élaboration.

Abstract:
In her book Mapping Marriage Law in Spanish Gitano Communities (2006), Susan Drummond challenges the disciplinary perspectives of comparative law and legal anthropology in her study of Gitano marriage practices. By reframing the way in which the “local” or “locale” is viewed—through an ethnographic study of Gitanos—she displaces the traditional boundaries ascribed to comparative law, with its focus on taxonomy and structure, and with legal anthropology's approach to culture. Her study not only elucidates how national and transnational law intersect, but highlights the complex interconnections between local law and the larger systems of law that attempt to regulate it. This detailed interdisciplinary depiction of the spatial and temporal dimensions of law demonstrates the importance of taking account of scale, projection, and representation that requires both comparative law and legal anthropology to rethink the nature of space and place and their relationship with law from both their macro‐ and microperspectives.

Abstract:
Histories of Lindau emphasize a remarkably conflict-free course of early reform in that particular locale. This view is established and maintained by multiple means, including hyper-credulity towards the peacefulness asserted by local authorities, anachronistic projections of the confessional “compromise” that was the Tetrapolitana back into the 1520s, and a deliberately narrow definition of key subjects, to exclude obvious contrary evidence. While Bernd Moeller has recently remarked that Lindau society was so harmonious that it is surprising there was any Reformation at all, archival sources actually indicate conflict in several areas pertaining to the early Reformation in Lindau, including interpersonal violence over key theological issues, the social conflict of the Peasant’s War, and stark communal divisions over iconoclasm, resulting in the ritual conflict of a feud. This article is both a particular historical corrective and a general historiographical illustration of how mythographic and historiographic modes may be entangled in early Reformation studies. Les ouvrages d’histoire montrent un début de Réforme remarquablement exempt de conflit dans l’histoire de Lindau. Cette interprétation fut établie et renforcée de plusieurs façons, dont une excessive crédulité envers les assertions de paix faites par les autorités locales, la projection anachronique de l’esprit de compromis confessionnel propre au Tetrapolitana de 1520, ainsi que la restriction délibérée des définitions de certains sujets essentiels, menée afin de réduire les contradictions patentes. Bien que Bernd Moeller ait récemment fait remarquer que la société de Lindau apparaît comme si harmonieuse que l’on peut s’étonner qu’il s’y soit même déroulé une Réforme, les documents d’archives révèlent plutôt l’existence de conflits dans plusieurs secteurs de Lindau au début de la Réforme, conflits prenant la forme, par exemple, de violences entre interlocuteurs lors de discussions sur des questions théologiques centrales, de conflits sociaux participant de la Guerre des Paysans, et de sérieuses divisions marquant la communauté au sujet de l’iconoclasme, ayant pour résultat un échange formel de représailles. Cet article cherche donc à la fois à corriger l’histoire et à mettre en lumière, par ce cas de figure, comment les usages mythographiques et historiographiques s’enchevêtrent et marquent les études des débuts de la Réforme.

Abstract:
As the fourth pillar of democratic governments, media has a significant influence in the formation of general conclusions among the masses. The bull has stomped its way into featured news story in Tamil Nadu several times in the last decade. From the time that people of Tamil Nadu prepared to celebrate Pongal in 2017, a large number of individuals from different urban communities of the state came together in open spaces, such as coastal areas and playgrounds, challenging a Supreme Court directive prohibiting the essentially provincial spectacle of Jallikattu. Convenient conclusions have frequently been drawn with regard to debilitating injuries and even deaths. The ‘game’ has never been directed by anyone with precise control. The present paper is an attempt to understand how a section of media, mostly newspapers, portrayed this sensitive issue. The review conducts a comparison between one English daily and one vernacular daily, both covering the Chennai locale in Tamil Nadu and attempts to examine the stand taken by print media in the projection of Jallikattu.

Abstract:
The land use land cover change and its modeling approach has recently been considered by the scientific community to observe environmental changes. Remote Sensing and Geographical Information System (GIS) give major techniques which can be useful in the analysis at the town locale as well as the city levels. RS data from Thematic Mapper sensor of 1998, 2002, 2010, 2014, and 2018, Operational Land Imager of 2018 were used for the analysis. The study used a supervised classification technique for classification, and Cellular Automata Markovian (CA-Markov) Model analysis was used for future projection of 2038. The result shows that the projected the year 2038 with 0.9079 K-standard value of stimulation, the study further uses Maximum likelihood classifier (MLC) a supervised classification method to classify the images. The study reveals a continuous pattern of urban growth from 3.96 km2 in 2018 to 4.73 in 2038 in terms of settlement growth, dense vegetation has decreased from 11.73 in 2018 to 8.55 in 2038 also shrubland has decreased from 44.82 to 36.30, the last bare land has increased more than all the classes from 162.69 to 173.69. The findings of the present study are useful for planners and decision-makers in sustainable natural resource management.

Full text
Abstract:
A new projective exact penalty function method is proposed for the equivalent reduction of constrained optimization problems to unconstrained ones. In the method, the original objective function is extended to infeasible points by summing its value at the projection of an infeasible point on the feasible set with the distance to the set. The equivalence means that local and global minimums of the problems coincide. Nonconvex sets with multivalued projections are admitted, and the objective function may be lower semicontinuous. The particular case of convex problems is included. So the method does not assume the existence of the objective function outside the allowable area and does not require the selection of the penalty coefficient.

Abstract:
Applied macroeconomists often compute confidence intervals for impulse responses using local projections, that is, direct linear regressions of future outcomes on current covariates. This paper proves that local projection inference robustly handles two issues that commonly arise in applications: highly persistent data and the estimation of impulse responses at long horizons. We consider local projections that control for lags of the variables in the regression. We show that lag‐augmented local projections with normal critical values are asymptotically valid uniformly over (i) both stationary and non‐stationary data, and also over (ii) a wide range of response horizons. Moreover, lag augmentation obviates the need to correct standard errors for serial correlation in the regression residuals. Hence, local projection inference is arguably both simpler than previously thought and more robust than standard autoregressive inference, whose validity is known to depend sensitively on the persistence of the data and on the length of the horizon.

Abstract:
The authors draw attention to the little researched pandemic of HIV/AIDS in the Western area of the Eastern Cape, South Africa. They use population projection programs and new historical case level data which has a broader base than the national ante natal clinic (anc) data. They demonstrate the utility of the component method for projecting urban population trends as opposed to commonly used mathematical (exponential or logistic) projections. While there is much more work involved in an urban component projection because of problems of recovering reliable in-migration data, the final product of the component projection are of such value to planners that it is suggested that all South African city planners could benefit from such projections. This study also attempts to establish that if the HIV pandemic is allowed to run unchecked, the total population of the Nelson Mandela Metropole will be just under two million people by the year 2021. Without Aids it would be between 2.5 and 4 million. The authors analyze the new data with a view to understand the probable historical vectors of the pandemic and to enable policy formulation, interventions and planning. Any attempt to forecast the course of an urban HIV pandemic is fraught with difficulties and uncertainties. These relate primarily to the number of assumptions which must be made in building forecasting models, often with historical data that is not reliable. The results of any model should therefore be treated with caution and must be used responsibly. That uncertainty, however, should not deter attempts at developing realistic forecasts for the future course of the HIV/AIDS pandemic at the urban level, since these local projections are essential in attracting and recruiting the attention of the stakeholder urban planners and managers who need to understand the possible impact of this disease on their communities, and to plan appropriately.

Abstract:
ABSTRACT Convergence maps of the integrated matter distribution are a key science result from weak gravitational lensing surveys. To date, recovering convergence maps has been performed using a planar approximation of the celestial sphere. However, with the increasing area of sky covered by dark energy experiments, such as Euclid, the Vera Rubin Observatory’s Legacy Survey of Space and Time (LSST), and the Nancy Grace Roman Space Telescope, this assumption will no longer be valid. We recover convergence fields on the celestial sphere using an extension of the Kaiser–Squires estimator to the spherical setting. Through simulations, we study the error introduced by planar approximations. Moreover, we examine how best to recover convergence maps in the planar setting, considering a variety of different projections and defining the local rotations that are required when projecting spin fields such as cosmic shear. For the sky coverages typical of future surveys, errors introduced by projection effects can be of the order of tens of percent, exceeding 50 per cent in some cases. The stereographic projection, which is conformal and so preserves local angles, is the most effective planar projection. In any case, these errors can be avoided entirely by recovering convergence fields directly on the celestial sphere. We apply the spherical Kaiser–Squires mass-mapping method presented to the public Dark Energy Survey science verification data to recover convergence maps directly on the celestial sphere.

Abstract:
Constructing a rational affinity matrix is crucial for spectral clustering. In this paper, a novel spectral clustering via local projection distance measure (LPDM) is proposed. In this method, the Local-Projection-Neighborhood (LPN) is defined, which is a region between a pair of data, and other data in the LPN are projected onto the straight line among the data pairs. Utilizing the Euclidean distance between projective points, the local spatial structure of data can be well detected to measure the similarity of objects. Then the affinity matrix can be obtained by using a new similarity measurement, which can squeeze or widen the projective distance with the different spatial structure of data. Experimental results show that the LPDM algorithm can obtain desirable results with high performance on synthetic datasets, real-world datasets, and images.

Abstract:
L’objectif de cette thèse est de proposer une méthodologie complète de reconstruction 3D d’objets sous-marins naturels, améliorée par une nouvelle méthode d’acquisition afin de permettre des mesures quantitatives. Il a d’abord fallu prendre en compte les différents problèmes liés au milieu sous-marin profond ; la contrainte principale est que le système utilisé pour faire l’acquisition des images doit être contrôlé à des profondeurs très importantes, jusqu’à 6000 mètres, à l’aide d’un véhicule positionné sur le fond. Ainsi, une méthode permettant l’acquisition automatique d’images a été développée, adaptée à tout type d’objet sous-marin de faible échelle (environ 1m3). L’acquisition d’image est réalisée avec un système de stéréovision contrÔlé par un bras manipulateur. La méthode que nous proposons permet de connaître les paramètres extrinsèques des caméras du système de vision, par le suivi d’une trajectoire définie par la géométrie de la tête stéréo. Ainsi, la trajectoire est générée par le déplacement d’une caméra sur la position de l’autre caméra par asservissement visuel. Avec cette méthode, nous pouvons enregistrer des images à intervalles réguliers directement liés à la géométrie de la tête stéréo. Ensuite, le modèle 3D de l’objet sous-marin est calculé à partir des images collectées et des paramètres des caméras. Le résultat final est une reconstruction 3D dense avec un plaquage de texture, qui permet de faire des mesures métriques. Mots-clés: métrologie 3D, vision par ordinateur, stéréovision, asservissement visuel, trajectoire d’acquisition, reconstruction 3D
The aim of this study is to propose a complete 3-dimension reconstruction method of natural submarine objects improved by a new acquisition method for quantitative measures, which can be used in operational conditions. First, it was necessary to take into account the various problems connected with the deep sea environment ; the main constraint is that the system used to collect images must be manipulated at very important depths, up to 6000 meters by an underwater vehicle positioned on the sea floor. Thus, a method allowing the automatic acquisition of images was developed, adapted to any type of small-scale submarine object (approximately 1m 3). The image acquisition is performed with a stereovision system operated by a manipulator arm. The method that we propose enables us to know extrinsic camera parameters by following a specific trajectory defined by the geometry of a stereo rig. Indeed, the trajectory is generated by the displacement of one camera onto the position of the other one by visual servoing. With this method, we can register images at regular intervals directly linked to the geometry of the stereo rig. Then, the 3D model of the underwater object is calculated from the collected images and camera parameters. The final result is a dense 3D reconstruction with texture mapping that enables metric measures. Keywords: 3D metrology, computer vision, stereovision system, visual servoing, camera trajectory, 3D reconstruction

Abstract:
En matière de réduction et de lutte contre les inégalités sociales et économiques, l’État est un acteur incontournable, jouant notamment un rôle de « chef d’orchestre ». Face au constat de déséquilibres territoriaux, l’action des collectivités est majeure en matière sociale et polyforme en fonction des spécificités territoriales et compétences allouées. Afin d’adapter leurs politiques publiques et répondre aux besoins sociaux des populations, les collectivités territoriales peuvent adopter une approche prospective. Dans cette optique, les modèles de projections démographiques localisées apportent des réponses mais celles-ci ne sont que partielles et montrent leur limites pour prévenir l’évolution d’autres phénomènes (isolement, compositions familiales, absence d’activité professionnelle, etc.). Si les microsimulations imposent un certain nombre de limites, elles satisfont cependant à deux aspects primordiaux de notre problématique. D’une part, en prenant en compte un plus large champ de variables et d’hypothèses, elles apportent une réponse plus précise sur les besoins futurs des populations. D’autre part, d’un point de vue méthodologique, les microsimulations sont adaptées à la dimension locale de la problématique et au maintien des liens entre les ménages et leur logement tout au long de la projection
When it comes to fighting against and reducing social and economic inequalities, the state is a key actor since it plays a “bandmaster” role. The action of local authorities towards territorial imbalances is crucial in social matters and is also multiform depending on territorial specificities and allocated competencies. In order to adapt their public policies and to answer populations’ social needs, local authorities may choose to adopt a forward-looking approach. In this context, local demographic projection methods might give some answers but those remain partial and show their limits when it comes to preventing the evolution of other phenomena such as seclusion, family setup, lack of professional activity, etc. While microsimulations show certain limits, they answer two primordial aspects of our problematic. On the one hand, by embracing a larger set of variables and hypotheses they offer a more precise answer to future populations’ needs. On the other hand, microsimulations are more adapted to the local aspect of the problematic from a methodological angle and they can preserve the link between households and their housing throughout the projection exercise

Abstract:
La circonscription administrative intermédiaire sous la Révolution et le Consulat. La projection locale d'une volonté politique. La loi du 22 décembre 1789 et celle du 28 pluviôse an VIII, genèses de l’actuelle distribution administrative du territoire, retranscrivent la volonté du pouvoir central de projeter localement son autorité. De l’une à l’autre, l’objectif centralisateur ne cesse d’être affirmé. Il évolue, en revanche, en fonction des variables circonstancielles, idéologiques, et politiques qui redéfinissent ses contours. Si l’organisation et les fonctions des administrations locales expriment de manière évidente cette évolution, il apparaît que c’est au niveau de l’échelon intermédiaire que l’expression est la plus forte. Paradoxalement, c’est également le niveau d’administration qui est le moins considéré par l’historiographie. Entre autres raisons, il en est une qui perdure : ce qui est placé « entre-deux » est par essence destiné à ne guère susciter l’intérêt. Une lecture linéaire et globalisante de la qualité d’intermédiaire qui doit être révisée à la suite de l’observation de la période étudiée. Du district de la Constituante au district de la Convention, de la municipalité de canton du Directoire à l’arrondissement du Consulat : à chaque instant réformateur, la circonscription administrative intermédiaire correspond à une réalité différente
Laws of December 22th 1789 and « 28 pluviôse an VIII », genesis of the ongoing territory’s administrative distribution, symbolize the central power’s will in terms of planning locally it’s authority. From one to the other, the centralizing objective keeps being claimed. On the other hand, it evolves functions of ideological and political variables that define it’s outlines. If local administrations’ organisation and duties obviously express this evolution, it appears it is by the intermediate rung that it’s expression is the the most apparent. Paradoxically, it is also the administration level whom is the less considered by historiography. One reason lasts : what is placed in-between is essentially meant to not give rise to interest. A linear and globalizing reading of the intermediate quality that must be reviewed in the aftermath of the studied period. From the « Constituante » district to the « Convention » district, from Directory township municipality to Consulate arrondissement: at every reforming instant, the intermediate administrative constituency correspond to a different reality

Dans cette thèse, nous avons présentons une méthode pour orienter automatiquement une carte d'environnement avec une scène locale.Dans la littérature, de nombreuses méthodes ont besoin d'orienter la carte d'environement pour obtenir une cohérence avec une scène locale. Cette orientation est dans la majorité descas effectuée de manière manuelle par un utilisateur. Nous présentons une méthode pour recaler automatiquement un carte d'environement avec une scène locale. Une caractéristique de notre approche est que nous n'avons pas besoin de créer un modèle 3D complet de la scène locale, ni d'interaction avec l'utilisateur. De plus, nous faisons que de simples hypothèses.Nous proposons un pipeline pour créer une représentation virtuelle de la scène en utilisant nos données d'entrée. Cette représentation comprend la scène globale représentée par la carte d'environement et la scène locale représentée par un objet de référence et son ombre.En utilisant la connaissance de la position de la source lumineuse principale sur la carte d'environnement, nous pouvons simuler l'éclairage et projeter une ombre sur le sol. Il est alors possible de comparer la forme de l'ombre calculée avec celle de l'ombre d'entrée pour récupérer la position correcte de la source lumineuse principale. L'orientation finale de la carte d'environement est directement liée à la position de cette source lumineuse principale.Nous fournissons une évaluation de l'approche proposée en calculant deux métriques qui comparent notre estimation d'angle avec les directions réelles au sol. Notre estimation d'orientation montre que notre méthode récupère une orientation de carte d'environement correcte
In this thesis, we have presented a method to register an environment map with a local scene automatically.In the literature, many methods need to orient the environmental map to be coherent with a local scene. This orientation is mostly done manually by a user. We present a method to register an environment map with a local scene automatically. A characteristic of our approach is that we do not need to create a complete 3D model of the local scene or have interaction with the user. Moreover, we are making simple assumptions.We propose a pipeline to create a virtual representation of the scene using our input data. This representation includes the global scene represented by the environment map and the local scene represented by a reference object and its shadow.By using the knowledge of the position of the main light source on the environment map, we can simulate the lighting and project a computed shadow on the ground. It is possible to compare the computed shadow shape with the input one to recover the correct position of the main light source. The final orientation of the environment map is directly related to the position of this main light source.We provide an evaluation of the proposed approach by calculating two metrics that compare our angle estimate with actual ground truth directions. Our orientation estimation shows that our method recovers a correct environment map orientation.In this thesis, we are interested in real input data. The environment map and the local scene are extracted from photographs or videos, which already contain a lighting rendering. It is therefore important to orient the environment map in a way that is consistent with the existing lighting in the local scene.We propose an automatic method, to orient an environment map to a local scene. This method is inspired by the behavior of light, drawing rays of light towards an object and attempting to match two shadows, one given as input and one calculated.We also use 3D data from the object we are considering. The originality is that we base our method on the way light behaves in order to calculate and match shadows. By matching the shadows, we can estimate the correct position of the environment map

Abstract:
In computer graphics a projection describes the mapping of scene geometry to the screen. While linear projections such as perspective and orthographic projection are common, increasing applications are being found for nonlinear projections, which do not necessarily map straight lines in the scene to straight lines on the screen. Nonlinear projections occur in reflections and refractions on curved surfaces, in art, and in visualisation. This thesis presents a new nonlinear projection technique called a trilinear projection that is based on the trilinear interpolation of surface normals used in Phong shading. Trilinear projections can be combined to represent more complicated nonlinear projections. Nonlinear projections have previously been implemented with ray tracing, where rays are generated by the nonlinear projections and traced into the scene. However for performance reasons, most current graphics software uses scanline rendering, where a scene point is imaged on a screen as a function of the projection parameters. The techniques developed in this thesis are of this nature. This thesis presents several algorithms used in trilinear projection: 1. An algorithm to analytically determine which screen locations image a given scene point. 2. An algorithm that correctly connects projected vertices. Each scene point may be imaged multiple times, which means a projected scene triangle may form from one to four different shapes of from two to nine vertices. Once connected, the projected shapes may be rendered with standard scanline algorithms. 3. An algorithm to more accurately render the curved edges between projected vertices. 4. A scene-space edge-clipping algorithm that handles continuity issues for projected shapes across composite projections. The trilinear projection technique is demonstrated in two different application areas: visualisation, and reflections and refractions. Specifically, various nonlinear projections that are congruent with pre-existing visualisation techniques are implemented with trilinear projections and a method for approximating the reflections and refractions on curved surfaces with trilinear projections is presented. Finally, the performance characteristics of the trilinear projection is explored over various parameter ranges and compared with a naive ray tracing approach.

Abstract:
Le cervelet permet l’apprentissage moteur et la coordination des mouvements fins. Pour ce faire, il intègre les informations sensorielles provenant de l’ensemble du corps ainsi que les commandes motrices émises par d’autres structures du système nerveux central. Les noyaux cérébelleux profonds (DCN) constituent la sortie du cervelet et intègre les informations provenant des cellules de Purkinje (PC), des fibres moussues et des fibres grimpantes. Nous avons étudié les connexions fonctionnelles entres les PC et les DNC in vivo, grâce à une stimulation optogénétique des lobules IV/V du cortex cérébelleux et à l’enregistrement multi unitaire du noyau médian. Nous avons ainsi identifié deux groupes de cellules au sein des DCN, présentant des caractéristiques propres au niveau de leur fréquence de décharge et de la forme des potentiels d’action, en accord avec la dichotomie établie par une précédente étude in vitro permettant de séparer les neurones GABAergiques des autres neurones. Nos résultats suggèrent que les PC contrôlent la sotie du cervelet d’un point de vue temporel. De plus, la ciruiterie interne des DCN conforte ce résultat de part le fait que les cellules GABAergiques ne produisent pas d’effet temporel au travers de l’inhibition locale
The cerebellum integrates motor commands with somatosensory, vestibular, visual and auditory information for motor learning and coordination functions. The deep cerebellar nuclei (DCN) generates the final output by processing inputs from Purkinje cells (PC), mossy and climbing fibers. We investigated the properties of PC connections to DCN cells using optogenetic stimulation in L7-ChR2 mice with in vivo multi electrode extracellular recordings in lobule IV/V of the cerebellar cortex and in the medial nuclei. DCN cells discharged phase locked to local field potentials in the beta, gamma and high frequency bands. We identified two groups of DCN cells with significant differences in action potential waveforms and firing rates, matching previously discriminated in vitro properties of GABAergic and non-GABAergic cells. PCs inhibited the two group of cells gradually (rate coding), however spike times were controlled for only non-GABAergic cells. Our results suggest that PC inputs temporally control the output of cerebellum and the internal DCN circuitry supports this phenomenon since GABAergic cells do not induce a temporal effect through local inhibition

Abstract:
Cette thèse examine empiriquement différentes questions-clés d'économie et de finance internationales sous le prisme de la montée des risques liés au changement climatique et aux politiques d'atténuation. Le premier chapitre analyse les déséquilibres mondiaux des comptes courants, particulièrement depuis la crise de 2008, en identifiant des facteurs comme le développement financier et les variables institutionnelles influençant ces déséquilibres par des variations de l’épargne et des investissements. Les prédictions de comptes courants montrent des excédents au Japon, en Chine et en Allemagne. Dans cette première partie, nous évaluons également l'impact des politiques d'atténuation du changement climatique en intégrant certaines variables politiques dans notre analyse. Les résultats montrent que des politiques environnementales plus strictes ou des taxes environnementales plus élevées sont associées à des excédents de la balance courante. Le deuxième chapitre examine l’impact des politiques environnementales sur le commerce international, concluant qu’une politique stricte réduit les émissions de CO2 dans les échanges, bien qu’une fuite de carbone soit observée via les importations de pays à politique environnementale plus souple. Le troisième chapitre évalue l’effet des catastrophes naturelles sur la balance des paiements, révélant un impact négatif à court terme, plus marqué dans les pays émergents, tropicaux, insulaires et côtiers. La thèse conclut que les risques climatiques et les politiques d’atténuation influencent les échanges internationaux et les flux de capitaux, et ces effets devraient s’intensifier à l’avenir
This thesis empirically examines various key issues in international economics and finance through the lens of rising risks associated with climate change and mitigation policies. The first chapter analyzes global current account imbalances, particularly since the 2008 crisis, identifying factors such as financial development and institutional variables that influence these imbalances through shifts in savings and investments. Current account predictions indicate surpluses in Japan, China, and Germany. In this first part, we also assess the impact of climate change mitigation policies by incorporating certain policy variables into our analysis. The results show that stricter environmental policies or higher environmental taxes are associated with current account surpluses. The second chapter examines the impact of environmental policies on international trade, concluding that strict policies reduce CO₂ emissions in trade, although carbon leakage is observed through imports from countries with less stringent environmental policies. The third chapter assesses the effect of natural disasters on the balance of payments, revealing a short-term negative impact, which is more pronounced in emerging, tropical, island, and coastal countries. The thesis concludes that climate risks and mitigation policies influence international trade and capital flows, with these effects expected to intensify in the future

Abstract:
AbstractOwing to the raised demands on process operation and product quality, the modern industrial process becomes more complicated when accompanied by the large number of process and quality variables produced. Therefore, quality-related fault detection and diagnosis are extremely necessary for complex industrial processes. Data-driven statistical process monitoring plays an important role in this topic for digging out the useful information from these highly correlated process and quality variables, because the quality variables are measured at a much lower frequency and usually have a significant time delay (Ding 2014; Aumi et al. 2013; Peng et al. 2015; Zhang et al. 2016; Yin et al. 2014). Monitoring the process variables related to the quality variables is significant for finding potential harm that may lead to system shutdown with possible enormous economic loss.

Full text
Abstract:
The optimization of soft x-ray production from a laser-produced plasma source is an important issue for several current lithography schemes. Recent experiments at Lawrence Livermore National Laboratory by R. Kauffman, D. Phillion, and R. Spitzer, indicate that the required conversion efficiency can be achieved using moderate laser intensities for a few select materials. Computer simulations of these experiments delineate the critical phenomena underlying these high conversion efficiencies, especially the role of the coupled hydrodynamic expansion and radiation flow in the plasma. By driving the plasma emission out of local thermodynamic equilibrium, photon output in the desired spectral region can be much greater than the black-body emissivity. These conditions can only be achieved under certain conditions which are determined by the incident laser intensity, essentially the electron temperature, and the excited electronic state populations within each ionization stage. Reliable simulations of the experiments require fairly detailed atomic physics databases since the prediction of photon output occurs in such a narrow spectral range. The computer program LASNEX is capable of coupling the hydrodynamic motion and a radiation field described by detailed atomic physics rates for laser produced plasmas. Two-dimensional simulations using this code are compared to the experimental results and are shown to be reliable in their interpretation of these results.

Full text
Abstract:
We consider the problem of restoring an image from the phase-sign function (the so-called one-bit of phase) and the Fourier magnitude using the method of generalized projections. A formal obstacle to implementing projection methods to obtain a solution is that the set of functions with a prescribed phase-sign function, while convex, is not closed. To close the set we add an appropriate set of limit functions and then show that the algorithm does not converge to one of the added limit functions (a good feature of the algorithm). While other algorithms exist for retrieval from signed magnitude, the advantage of generalized projections is that a certain type of error reduction property is assured—provided that the algorithm does not stagnate in a trap (a local minimum) or a tunnel (a region where sets are nearly parallel). To the best of our knowledge this claim is not made by competing algorithms.

Abstract:
We shed new light on the short-term dynamic effects of cyclones on local economic growth in India. We proxy local GDP growth with night-time light intensity data and construct a cyclone index that varies across months and districts depending on windspeed exposures. Using local projections on highly granular data for the period 1993M1-2011M12, we find that yearly estimations hide large short-term differential impacts and that the negative impact of cyclones is the largest between 4 and 8 months after the event.

Full text
Abstract:
We investigate whether investments in renewable energy – solar and wind plants – create jobs in the municipality where they are located. Using 13 years of monthly data, we exploit the variation in the timing and size of investment projects across more than 3,200 municipalities in Spain, a country with substantial investments in this area. We use a new estimator for staggered differences-in-differences analysis that extends the local projections approach with clean controls (Dube et al., 2022). We find strong heterogeneity in the magnitude and pattern of the impacts of solar and wind investments. On average, solar investments increase employment by local firms, but the effects on the unemployment of local residents are weak. The effects of wind investments on local employment and unemployment are mostly non-significant. These findings have important implications for public policy.
