Brandou, Vincent. "Stéréovision locale et reconstruction 3D/4D." Nice, 2008. http://www.theses.fr/2008NICE4093.
Повний текст джерелаThe 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

Повний текст джерелаWhen 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

Повний текст джерелаLaws 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
Larvy, delariviere Ulysse. "Orientation automatique de carte d'environement autour d'une scene locale." Thesis, Reims, 2019. http://www.theses.fr/2019REIMS024.
Повний текст джерелаIn 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

Повний текст джерелаThe 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

Повний текст джерелаThis thesis empirically examines various key issues in international economics and finance through the lens of rising risks associated with climate change and mitigation policies. In its first chapter, it addresses the issue of global current account imbalances by analyzing the forces explaining their dynamics, particularly since the 2008 global financial crisis. It empirically evaluates the factors that could potentially explain the persistence of global imbalances in certain advanced, emerging, and low-income countries. The global financial crisis represents, according to our estimations, a structural break in the determination of current account balance determinants. Financial development, financial openness, and institutional variables are significant factors that influence the current account balance through changes in investment and savings behaviors. We then use our estimations to predict equilibrium current accounts and calculate the contribution of underlying factors. Despite some uncertainty around the estimates, our models are able to explain most observed current account configurations, showing only a surplus compared to equilibrium in the cases of Japan, China, and more recently, Germany. Following this general analysis, taking into account the impact of climate change mitigation policies shows that stricter environmental policy or high levels of environmental taxes lead to current account surpluses. Considering this potential impact of climate change mitigation policies, Chapter 2 examines the effects of environmental policy on international trade flows. It evaluates whether tightening environmental policy encourages the relocation of highly polluting activities. The results show no evidence of carbon leakage through international trade, as strict environmental policy generally leads to a reduction in CO2 emissions embodied in traded goods and services, both at the aggregate and sectoral levels. However, we find evidence of carbon leakage when considering imports from countries with less stringent environmental policies. Finally, Chapter 3 examines the effects of different types of climate events on various components of the balance of payments. We apply the local projection method to panel data to assess the impact of natural disasters on the balance of payments. This impact on the current account balance is negative in the short term and disappears one year after the disaster. Our results show that all components of trade decrease following a disaster. Service imports take the longest time to return to their initial state. The negative impact is greater in emerging countries than in more advanced ones. Similarly, in tropical, island, and coastal countries, the effects are more pronounced. Our work shows that climate change risks and environmental policies play an important role in international trade in goods and capital flows. These effects are expected to strengthen in the coming decades and could constitute fundamental factors in international economic and financial dynamics
Ahiati, Veroncia Sitsofe. "Cardinal spline wavelet decomposition based on quasi-interpolation and local projection." Thesis, Stellenbosch : University of Stellenbosch, 2009. http://hdl.handle.net/10019.1/2580.
Повний текст джерелаWavelet decomposition techniques have grown over the last two decades into a powerful tool in signal analysis. Similarly, spline functions have enjoyed a sustained high popularity in the approximation of data. In this thesis, we study the cardinal B-spline wavelet construction procedure based on quasiinterpolation and local linear projection, before specialising to the cubic B-spline on a bounded interval. First, we present some fundamental results on cardinal B-splines, which are piecewise polynomials with uniformly spaced breakpoints at the dyadic points Z/2r, for r ∈ Z. We start our wavelet decomposition method with a quasi-interpolation operator Qm,r mapping, for every integer r, real-valued functions on R into Sr m where Sr m is the space of cardinal splines of order m, such that the polynomial reproduction property Qm,rp = p, p ∈ m−1, r ∈ Z is satisfied. We then give the explicit construction of Qm,r. We next introduce, in Chapter 3, a local linear projection operator sequence {Pm,r : r ∈ Z}, with Pm,r : Sr+1 m → Sr m , r ∈ Z, in terms of a Laurent polynomial m solution of minimally length which satisfies a certain Bezout identity based on the refinement mask symbol Am, which we give explicitly. With such a linear projection operator sequence, we define, in Chapter 4, the error space sequence Wr m = {f − Pm,rf : f ∈ Sr+1 m }. We then show by solving a certain Bezout identity that there exists a finitely supported function m ∈ S1 m such that, for every r ∈ Z, the integer shift sequence { m(2 · −j)} spans the linear space Wr m . According to our definition, we then call m the mth order cardinal B-spline wavelet. The wavelet decomposition algorithm based on the quasi-interpolation operator Qm,r, the local linear projection operator Pm,r, and the wavelet m, is then based on finite sequences, and is shown to possess, for a given signal f, the essential property of yielding relatively small wavelet coefficients in regions where the support interval of m(2r · −j) overlaps with a Cm-smooth region of f. Finally, in Chapter 5, we explicitly construct minimally supported cubic B-spline wavelets on a bounded interval [0, n]. We also develop a corresponding explicit decomposition algorithm for a signal f on a bounded interval. ii Throughout Chapters 2 to 5, numerical examples are provided to graphically illustrate the theoretical results.

Повний текст джерелаEsta dissertação estuda o perfil temporal do impacto das crises bancárias sistêmicas sobre as taxas de suicídio usando um painel de 53 países entre 1980 e 2016. Usamos a metodologia desenvolvida por Oscar Jordà em 2005, as Projeções Locais, para medir este impacto. Com foco num horizonte de cinco anos, fica claro que os efeitos adversos das crises bancárias sistémicas persistem ao longo desse horizonte de tempo nas taxas de suicídio. Com este estudo, foi identificado um efeito positivo entre crises bancárias e taxas de suicídio. Além disso, este estudo está de acordo com estudos anteriores, uma vez que foi observado que esse efeito é de curta duração.
This thesis studies the temporal profile of the impact of systemic banking crises on suicide rates using a panel from 53 countries between 1980 and 2016. A methodology developed by Oscar Jordà in 2005, the Local Projections, was used to measure this impact. Focusing on a five-year horizon, it is clear that systemic banking crises' adverse effects persist throughout this time horizon on suicide rates. With this study, a positive effect was identified between banking crises and suicide rates. Moreover, this study is consistent with previous studies since it was observed that this effect does not last for long.

Повний текст джерелаThis thesis aims to understand the impact of structural reforms on labour productivity growth and income inequality in developing countries, while assessing the effectiveness of International Monetary Fund (IMF) conditionality programs in promoting these reforms.The first chapter examines how reforms, particularly those related to trade, domestic finances, and product markets, influence labour productivity growth. It contributes to the literature by documenting primarily the channels and the order in which reforms should be implemented.The results show that these reforms increase labour productivity. An analysis of the mechanisms involved reveals that structural reforms do not so much favor structural change, but rather productivity growth within sectors. However, our results underscore that the level of human capital plays a crucial role in determining the response of structural change to structural reforms. To optimize the productivity effects of reforms, our conclusions suggest the need to adopt a ``gradual approach'' in implementing the reforms.In the second chapter, we focus on the distributional effects of financial reforms, namely how they affect income distribution and inequality. The results indicate that financial liberalization reforms are associated with a significant reduction in income inequality. It is also shown the importance of adopting a reform strategy ensuring sequencing and complementarity between domestic financial reforms and external financial reforms to maximize the benefits of reducing income inequality.Finally, the third chapter highlights the role of the IMF in promoting structural reforms. The results indicate that the IMF promotes structural reforms through its conditionality programs. Our conclusions show that the diversity of imposed conditions has a differentiated impact on sectoral reforms and that the impact of conditionality programs cannot be separated from national political factors

Повний текст джерелаThis dissertation deals with reconstruction algorithms designed for the development of new X-Ray imaging systems compliant with interventional conditions, and dedicated to surgeon guidance for interventions such as pedicle screw insertion. After a presentation of the medical and technological background, we gather the main results in 2D tomography that enable the comprehension of truncated data tomographic problems, and we underline that the filtered backprojection method, though traditionally ignored in literature of local tomography, behaves very well in many cases. A state-of-the-art of the use of wavelets in tomography is then performed, in which we enhance links between approaches based on the filtered backprojection method, and wavelet-vaguelette-like methods. A new method for inversion of the Radon transform is then proposed; it relies on theoretical results by M. Holschneider, and we show that this new method is well suited for the processing of local data (for the interior problem, or the limited-angle problem as well). We finally present a completely different approach, in which a vertebra surface is reconstructed according to two fluoroscopic images and a statistical model of vertebra surface; we use several edge detectors (with wavelets, or active contour methods), and we show that they lead to satisfying reconstruction results when applied to a numerical phantom

In the second part, concerning Sustainable Touristic Projects, to consolidate this work the case-study “Mata de Sesimbra” Project, in Portugal, is presented and analysed – the first national project that combines building constrution, sustainable ecotourism and nature conservation, developed by the real estate company Pelicano in partnership with the ONG World Wildlife Fund and BioRegional – following the example of the well succeeded BedZed Project in the United Kingdom (an eco-village where its residents can have a ecofriendly style of life, with the comfort and quality of life of nowadays). Therefore, the entities involved and similar projects are presented, before the analysis of the project’s detail plan and environmental management plan. This investigation aim consists in demonstrating the merit of such projects in the local development, its positive and negative impacts, indicating the instruments that guide them and the obstacles in its implementation, as a guide line for similar iniciatives. Based on the documentation related to it, the project is analysed by three approaches: territorial (project development and land-use plans followed), social-cultural (the relationship between local community and the touristic endeavour) and economic (tourism importance to the local economy, specially of this kind of innovative projects), taking into account the environmental issue cross-cutting these approaches, trying to answer the starting point questions: How to create local value with the “Mata de Sesimbra” Project? Which are the project management, barriers and supports inherent to sustainable touristic development in Sesimbra?

Повний текст джерелаA importância crescente do município no campo educativo, a emergência de novos discursos, de novos actores educativos locais e de novas formas de organização das ofertas educativas formais e não formais coloca a governação local perante novos desafios, exigindo a adopção de novas práticas locais. Este estudo visa compreender o Projecto Educativo Local (PEL) do “Município XXI”, perceber a sua importância e o seu processo de construção e elaboração. Ambiciona conhecer o desenvolvimento deste processo: a sua origem, os actores que se envolveram e o seu grau de participação, o papel do Conselho Municipal de Educação (CME), os parceiros do município e sua cooperação e a assumpção ou não de uma proposta de programas e serviços ao nível da educação formal e não formal. Como questão central procura saber se o PEL e o seu processo de construção traduzem princípios da Carta do Movimento das Cidades Educadoras, no sentido de se testar essa conformidade e de se esclarecer se houve intenção estratégica/política municipal a esse nível, para perceber qual foi o contributo da integração na AICE relativamente à sua construção e ao alcance de um Território Educativo em Rede, de uma “Cidade Educadora". O estudo propõe-se também compreender a aproximação dos cidadãos aos centros e processos de tomada de decisão e dispõe-se quase no final, em género de reflexão, a averiguar, se após o mesmo se verificou maior sensibilização dos agentes educativos locais relativamente a esta problemática. Em síntese, o estudo visa analisar o PEL e a sua primeira etapa, numa dialéctica, dos princípios às práticas. Tendo como enquadramento teórico a Administração Escolar, as Políticas Educativas e alguns referenciais das Ciências Sociais efectuámos no primeiro capítulo abordagens relacionadas com a compreensão do papel dos municípios na educação, da “Cidade Educadora”, da territorialização e projecto educativo local, da descentralização e democracia/formas de participação e das redes educativas, actores e parcerias. Os segundo e terceiro capítulos relacionam-se com a componente prática centralizada num estudo de caso, de carácter exploratório, realizado ao PEL do “Município XXI” e ao desenvolvimento do seu processo de construção. No capítulo IV apresenta-se, analisa-se, interpreta-se os resultados, efectua-te uma análise SWOT, tecem-se as considerações finais e apresenta-se o contributo e as limitações do estudo. O nosso estudo confirmou a existência do PEL, a sua origem é de iniciativa municipal impulsionado pela integração na AICE, consubstanciou-se numa intenção política estratégica dos intervenientes municipais e contempla tanto a educação formal como a não formal. Parece-nos adequado validar a sua importância como um referencial estratégico, articulado e integrador, apesar de nesta primeira etapa ainda não estar articulado com o projecto educativo do agrupamento escolar. O PEL busca um desempenho em respeito pela Carta das Cidades Educadoras, traduzindo os seus princípios em número considerável. O CME aprovou o PEL e um espaço que possibilitasse a participação comunitária. Durante a construção do PEL houve uma Participação Cidadã muitíssimo fraca a deslizar para a não participação. No estudo reforça-se a necessidade de um maior investimento na chamada à participação, do aumento da própria implicação dos cidadãos e da sua aproximação aos centros de decisão, pois ainda se observa um afastamento. ABSTRACT: The increasing importance of the city in the educative field, the emergency of new speeches, new local educative actors and new forms of organization of the formal and not formal educative offers places the local government before new challenges, demanding the adoption of new practical places. This study it aims at to understand Project Educative Local (PEL) of “City XXI”, to perceive its importance and its process of construction and elaboration. It intends to know the development of this process: its origin, the actors that if had involved and its degree of participation, the paper of the City council of Education (CME), the partners of the city and its cooperation and the acceptance or not of a proposal of programs and services to the level of the formal and not formal education. As central question search to know if the PEL and its process of construction translates principles of the letter of the movement of the cities educators, in the direction of if to test this conformity and of if clarifying if had strategical intention/municipal politics to this level, to perceive which was contribute of the integration in the AICE relatively to its construction and the reach of an Educative Territory in Net, of a “City Educator”. The study it is also considered to understand the approach of the citizens to the centers and processes of decision taking and is made use almost in the end, in form of reflection, to inquire, if after the same greater was verified sensitization of the local educative agents relatively to this problematic one. In synthesis, the study it aims at to analyze the PEL and its first stage, in a dialectical, of the principles to the practical ones.

Повний текст джерелаO impacto das crises bancárias sistémicas tem efeitos severos na economia ? tão severos ao ponto de por vezes não se observar sinais de recuperação. Será que este impacto afeta o sector da educação? Em princípio, durante uma recessão existem fatores que apontam para um aumento nas matrículas terciárias e outros que apontam para o contrário. Tanto quanto sabemos, não existem estudos que usam dados em painéis que investiguem o efeito médio de crises bancárias nas matrículas terciárias. A ambição deste estudo passa por investigar o efeito de crises bancárias sistémicas nas matrículas terciárias num painel de 80 países entre o período de 1980 e 2017. A metodologia adotada foi as projeções locais de Jordà (2005). Os resultados demonstram um efeito nulo, ou seja, as matrículas terciárias parecem "sobreviver" a um choque de grande magnitude. Como o nível de rendimento de um país é um fator que pode influenciar as matrículas terciárias, complementámos a nossa análise com a separação por níveis de rendimento i.e. países de baixo-, meio-, e alto-rendimento. Nos países de baixo-rendimento um choque de uma crise bancária provoca uma diminuição nas matrículas terciárias. As conclusões a que chegámos contribuem para a compressão do impacto de crises bancárias sistémicas na educação.
The impact of systemic banking crises has severe effects on the economy ? so severe that sometimes the economy shows no signs of recovery. Does this impact reach the higher education sector? In principle, during a recession there are factors that point to an increase of tertiary enrollments and others that point in the opposite direction. To the best of our knowledge, there are no studies using panel data that estimate the effect of banking crises on tertiary enrollment. The objective of this paper is to investigate the impact of systemic banking crisis on tertiary enrollments in a large panel of 80 countries between 1980 and 2017. The methodology adopted was local projections by Jordà (2005). The results show a null effect meaning that tertiary enrollment "survives" to a shock of great magnitude. As income level is a factor that may influence tertiary enrollments, we complemented our analysis by looking at different income level groups i.e. low-, middle- , and high-income countries. We find that in low-income countries a banking crisis shock leads to a decrease of tertiary enrollments. Our findings contribute to improve our understanding of the impact of systemic banking crises on tertiary education.

Повний текст джерелаThe processes of globalization, regionalization and decentralization have created different effects on local dynamics, national and international, causing a higher participation of sub-state entities in the international arena. This action, which may be encouraged by the central government's inability to meet the interests of local authorities on the national and international scene, as well as various political and administrative elements, cultural and economic, has become a phenomenon increasingly taken with greater importance and recognition. This has established an initiative that has spread not only on the European continent but also other geographical areas, such as Latin America. These actions have achieved great traction and interest in a dynamic regarding not only regional but also global in the interests of the local sphere. In this international front, local authorities have projected, on the one hand, through different tools (individual and / or collective), strategic actions contributing to local development, on the other hand, actions that allow them to cooperate and conquer significant spaces on top scenes and consolidated as essential players in processes and important regional and global scenes. This inclusion of non-central governments on the international scene, accompanied by the appreciation of the local sphere, the opening of spaces and an evolution of the international discourse about their role in global issues, regional and national, is an element to project the beginning of a change in the landscape of the international system. This paper studies the emergence of new actors on the international scene and particularly the international influence of local governments on this arena. In this context, we have also identified the process of commitment and implementation of such actions by cities around the world, particularly the activities of Barcelona in Spain, and Medellín in Colombia . Additionally, we have been concerned about the recognition and inclusion of local government in higher structures within regional and global frameworks, such as Mercosur and the UN. This has been done, in part, through the collective action of cities and a network organization, such as networks of Mercociudades and UCLG

This dissertation consists of three essays in asymmetric empirical macroeconomics. Making macroeconomic policies has become increasingly difficult because of intricate relationships among macroeconomic variables. In this dissertation, we apply state-of-the-art macroeconometric techniques to investigate asymmetric relationships between key macroeconomic aggregates. Our findings have important macroeconomic policy implications. An analogue to the Phillips curve shows a positive relationship between inflation and capacity utilization. Some recent empirical work has shown that this relationship has broken down when using data after the mid-1980s and several popular explanations for this changing relationship, including advancements in technology and globalization, were put forward as possible explanations. In the first essay, we empirically investigate this issue using several threshold error correction models. We find, in the long run, a 1% increase in the rate of inflation leads to approximately a 0.0046% increase in capacity utilization. The asymmetric error correction structure shows that changes in capacity utilization show significant corrective measures only during booms while changes in inflation correct during both phases of the business cycle with the corrections being stronger during recessions. We also find that, in the short run, changes in the inflation rate do Granger cause capacity utilization while changes in capacity utilization do not Granger cause inflation. The Granger causality from inflation to capacity utilization can be interpreted as supporting recent calls made in the popular press by some economists that it may be desirable for the Federal Reserve Bank to try to induce some inflation in an effort to stimulate the economy. In the second essay, we examine the role of consumer confidence on economic activities like households’ consumption in good and bad economic times. We consider the “news” versus “animal spirit” approach interpretation of consumer confidence. In the wake of the Great Recession of 2008-09, many have called for confidence-boosting policies to help speed up the recovery. A recent study has reinforced these policy calls by showing that the Michigan Consumer Confidence Index contains important information about “news” on future productivity that has long-lasting effects on economic activities like aggregate consumption. Using US data, we show this conclusion is more nuanced when considering an economy that has different potential states. We investigate regime-switching models which use the National Bureau of Economic Research US business cycle expansion and contraction data to create an indicator series that distinguishes bad and good economic times and use this series to investigate impulse responses and variance decompositions. We show the connection between consumer confidence to some types of consumer purchases is important during good economic times but is relatively unimportant during bad economic times. We also use this type of model to investigate the connection between news and consumer confidence and this connection is also shown to be state dependent. In the context of the animal spirits versus news debate, our findings show that during economic expansions, consumer confidence shocks likely reflect news, while during economic contractions, consumer confidence shocks are consistent with animal spirits. These findings also have important implications for recent policy debates which consider whether confidence boosting policies, like raising inflation expectations on big-ticket items such as automobiles or business equipment, would lead to a faster recovery. The third essay investigates expectation shocks and their effect on the economy. For instance, this essay investigates whether the economy responds to expectation shocks in an importantly asymmetric way. A growing literature shows that agents' expectation about the future can lead to boom-bust cycles. These studies so far ignore the transmission effects of expectations on current economic activities across the policy regimes. Using the Survey of Professional Forecasters and Livingstone Survey data, this study empirically investigates the effects of expectation shocks on macroeconomic activities when policy regimes shift. Identifying a structural shock to expectations by using the timing of information in the forecast surveys and actual data releases, we show that the effects of agents' expectations about the future on current macroeconomic activities are asymmetric across the policy regimes. In particular, we find that a perception of good times ahead typically leads to a significant rise in current measures of economic activity in a hawkish regime relative to a dovish regime. We also find that monetary policy's reactions to agents' expectations are asymmetric across the policy regimes. Our findings do not support the views of critics of the central banks, who argued that keeping monetary policy too easy for too long is responsible for fueling the booms. Instead, our findings support the traditional view that a positive (negative) expectation about the future coincides with an anticipatory tightening (easing) of monetary policy.

Повний текст джерелаLocal governments in the United States have generally experienced fiscal distress in the past decade, due to the economic downturn, reduction in Federal and State aid, and rising costs for providing services partly due to pensions and healthcare. Many governments are worried about their long-term financial sustainability.
Professional organizations such as Government Finance Officers Association (GFOA) have been recommending budgeting with a multi-year fiscal planning framework as a best practice, noting that it can assist local governments in understanding their fiscal outlook and in making budget decisions that strategically address their future fiscal issues and support their long-term strategic priorities. Internationally, Medium-Term Expenditure Frameworks (MTEFs) have been practiced by the central governments of 132 countries with empirical studies showing a positive impact on improving fiscal discipline, financial sustainability and allocative efficiency. (World Bank, 2013) However, limited studies exist on such practices among local governments in the United States.
This dissertation draws on existing literature on MTEFs, multi-year (revenue) projections, and financial sustainability to examine the factors that may affect the usefulness of multi-year fiscal planning to policy makers. A survey instrument, which serves as the primary data source for this research, was distributed to local governments. Five hundred and thirty-seven effective responses were collected from different types of local governments in 44 states. Statistical analysis was then conducted, using multiple regression and cumulative logistic regression, to evaluate the potential impact from different features of multi-year framework on its perceived usefulness as measured by survey respondents' ratings. In addition, panel data studies were employed on certain municipalities that use multi-year fiscal planning to study the impact of different features of this framework on nine fiscal health indicators. Five-year financial data from years 2003, 2005, 2007, 2009 and 2011 in the GFOA database was used to construct these fiscal health indicators developed largely based on a modified version of Brown's 10-point system (Brown, 1993).
The results contribute to a better understanding of the current status and practices of multi-year projections and fiscal planning used in local governments in the United States. It also helps shed light on whether implementing multi-year framework makes a positive impact on achieving different policy goals (e.g., fiscal health) and what factors affect its effectiveness or usefulness.
In particular, statistical analysis results suggest that several features of multi-year fiscal planning have a statistically significant positive impact on fiscal health and other budget goals. Identified factors include: the quality and content of projection material (e.g., whether strategies or options are included to address identified issues); the purpose of multi-year projections and fiscal planning (e.g., whether it targets at achieving certain fund balance levels); the timing of presenting multi-year projections results the legislative authority (which shows the connection between multi-year projections and the annual budget); the engagement of key stakeholders in developing multi-year projections and fiscal plans; the integration between multi-year fiscal planning and strategic planning; and the history or experience of using this policy tool.
These findings support the claims by researchers and practitioners that multi-year projections and fiscal planning can help improve a local government's fiscal health and promote other budget goals. In particular, it offers empirical evidence that certain features of the multi-year fiscal planning framework can affect its usefulness. This research fills a gap in existing literature and collects useful information that lay the groundwork for future research.

Повний текст джерелаThis work of thesis was motivated by the will to measure the transmission of an electronic beam of low energy through a film. These measures were realized with the electron projection microscope, the use of which is based on three key elements: the tip, the object, the system of detection. The made measures allow, on the same object, to determine the transmission according to the kinetic energy of the incidental electrons for energies included between some tens and several hundreds of électronvolts. To bring to a successful conclusion these measures, we developed a procedure to fabricate freestanding ultra thin films. Their characterization by electronic microscopy showed that this procedure is reliable and that it allows to obtain freestanding films of some nanometers of thickness about side sizes of some tens of micrometers. We more particularly bent over golden nano porous films and over continuous nickel films. However, encouraging attempts (Co, Au/Co/Au, aluminum oxide, tétracontane) using this procedure indicate that this fabrication method can be spread. Transmission measurements realized on gold and nickel allowed to reach characteristics inherent to the material. Indeed, they constitute a new method of determination of the inner potential U and of inelastic mean free path Λ. We thus demonstrate through this work that the measure of the transmitted intensity of a coherent electrons beam by an ultra thin film can be realized in a local scale even on a unique cristallite. Furthermore, nano porous films constitute objects acting on the amplitude and the phase of the electronic wave. It is thus possible to modulate the wave electronic function by the control of the thickness and the porosity of the film

Повний текст джерелаA actualidade tem sido marcada por várias crises, não só a nível económico mas também a nível ambiental e social. De forma a contornar estas dificuldades é urgente actuar a nível dos problemas que ocorrem na sociedade. No entanto, é necessário que as comunidades se adaptem, que sejam resilientes, ou seja, tenham a capacidade de suportar perturbações sem colapsar, adaptando-se às novas condições de forma a reequilibra-las e a tornar a sociedade mais sustentável. Este discurso de sustentabilidade tem sido largamente discutido devido aos problemas que a sociedade enfrenta, e tem enfrentado, ao longo dos anos. Para a atingir é fundamental agir de forma mais incisiva. No entanto, a maioria dos problemas que impedem a sua prossecução possuem raízes locais, sendo assim indispensável actuar num âmbito territorial mais reduzido. De acordo com esta abordagem, é fundamental agir a nível da sustentabilidade local, com a colaboração de todos, como factor estratégico para uma sustentabilidade global. A realização desta dissertação teve como principal objectivo avaliar projectos inovadores, na Área Metropolitana de Lisboa, que contribuem para a sustentabilidade local. A sua avaliação foi realizada de modo a compreender as dinâmicas sociais e os motivos de sucesso, incidindo também na análise do papel que o Engenheiro do Ambiente desempenha ou que pode desempenhar neste tipo de projectos. Deste modo, foi possível verificar que os projectos em estudo seguiam um modelo de desenvolvimento integrado. Este facto é um dos motivos de sucesso dos projectos, pois torna-os eficazes na resolução dos problemas locais. Relativamente à mobilização da população, verificou-se que esta é cada vez maior. Os cidadãos demonstram, cada vez mais, uma preocupação e sentido de pertença pelo espaço público, e a sua cooperação com as autoridades locais e a participação nas acções a realizar para a execução dos projectos é visível de uma forma crescente na nossa sociedade. A colaboração de um Engenheiro do Ambiente foi verificada em alguns dos projectos, sendo que noutros essa participação não ocorreu. No entanto, considera-se que a colaboração do Engenheiro do Ambiente é sempre uma mais-valia para este tipo de projectos devido às suas competências profissionais e ao contributo que pode oferecer para a sua realização e sucesso.

Повний текст джерелаNowadays, it has become easy to edit images, such as blurring an area, or changing it to hide or add an object, a person, etc. Image editing is one of the basic tools of most image processing software. In the context of audio signals, it is often more natural to perform such an editing in a transformed domain, in particular the time-frequency domain. Again, this is a fairly common practice, but not necessarily based on sound theoretical arguments. Application cases include the restoration of regions of the time-frequency plane where information has been lost (e.g. phase information), the reconstruction of a degraded signal by an additive perturbation well localized in the time-frequency plane, or the separation of signals localized in different regions of the time-frequency plane. In this thesis, we propose and develop theoretical and algorithmic methods to solve this issue. We first formulate the problem as a missing data reconstruction problem in which the missing data are only the phases of the time-frequency coefficients. We formulate it mathematically, then we propose three methods to solve it. Secondly, we propose an approach that consists in attenuating a source of degradation with the assumption that it is localized in a specific region of the time-frequency plane. We consider the case where the signal of interest is perturbed by an additive signal and has an energy that is more widely spread in the time-frequency plane. We formulate it as an optimization problem designed to attenuate the perturbation with precise control of the level of attenuation. We obtain the exact solution of the problem which involves operators called Gabor multipliers

Повний текст джерелаO Programa Agenda 21 Local é um projecto que nasceu dos compromissos adoptados pelos países participantes na Conferência das Nações Unidas sobre Ambiente e Desenvolvimento (CNUAD) também conhecida por Cimeira do Rio, na qual foram estipulados uma serie de objectivos com vista à promoção e divulgação de praticas de Desenvolvimento Sustentável à escala global. Para obter uma sociedade mais sustentável era necessário uma mudança de paradigma de métodos de desenvolvimento e de envolvimento cívico, um facto consagrado na Agenda 21 Local, dada a ênfase que o programa coloca na realidade local, e no papel que os principais stakeholders locais assim como toda a comunidade têm na elaboração de respostas para problemas localmente contextualizados e portanto específicos. Existem processos Agenda 21 Local um pouco por todo o mundo, mas é na Europa, e mais especificamente na União Europeia, que foram desenvolvidos e aplicados o maior numero de processos, tendo sido alguns países europeus pioneiros a nível mundial na implantação dos mesmos. Em Portugal só recentemente a Agenda 21 Local começou a ser tomada em consideração como instrumento de gestão local, potenciador de desenvolvimento sustentável, permitindo uma participação e envolvimento dos cidadãos, e gerador de oportunidades a nível económico e social. A Agenda 21 Local tem-se deparado com vários obstáculos à sua efectiva difusão e implementação no território nacional, um facto que se relaciona com problemas de cariz politico e institucional, bem como de cultura cívica e participativa no geral. O presente trabalho teve como objectivo central realizar uma caracterização social, económica e ambiental do município de São Brás de Alportel, com o propósito de desenvolver um Fórum Agenda 21 Local, discutindo os resultados do processo de investigação, e potenciando o debate e elaboração de propostas de intervenção por parte dos participantes, traçando o caminho para um futuro desenvolvimento e aplicação das restantes fases do processo Agenda 21 Local no município de São Brás de Alportel.

Повний текст джерелаThis paper aims to investigate whether government spending multipliers are different according to the state of the business cycle for the Brazilian economy during the period 1999:I-2016:II. In order to do so we use Jordà\'s Local Projection Method to estimate impulse response functions and fiscal multipliers under two different regimes: recession and expansion. To define the different regimes we use several variables commonly used in the literature: the output gap, the capacity utilization level, the GDP growth rate, the unemployment rate and CODACE. The nonlinear model estimations result in larger multipliers, after one and two years, in periods of economic recession than in periods of economic expansion, regardless of the variable chosen to differentiate regimes. However, the multipliers do not seem to be statistically different between regimes. Unfortunately, as observed by Ramey and Zubairy (2017), long historical series are fundamental for the adequate estimation of fiscal multipliers and their absence for the Brazilian economy does not allow anyone to say much about the subject.

Access Networks are experiencing an accelerated evolution in order to get ready to support new broadband services, both to the residential and business markets. Business customers are already introducing multimedia services in their facilities. There are signs that interactive broadband services to residential customers are becoming a major growth industry mainly due the actual existing competition between Telecoms and CATV operators. Consequently, the necessity of implementing new strategies arose, mainly in what concerns to the Access Network. The present dissertation refers to the above mentioned matters and tries to analyse the potentialities of the emerging technical solutions which will support the new broadband services.

The assessment of the model is based on two criteria, absence of mesh size effect in finish elements computations and agreement of experimental and numerical results for some typical ductile fracture tests. The first proposal consisted of adopting some nonlocal evolution equation for the porosity involving some convolution integral. The second proposal is an extension of Gurson's condition of homogeneous boundary strain rate, to the case of conditions of inhomogeneous boundary strain rate. In the second part, one define a model for porous ductile material containing two "populations" of cavities, extending that of Perrin et al.

This article applies local projection to estimate the impulse response function of a small open economy, Taiwan. There are several advantages of local projection: local projection can be calculated by simple ordinary least square; it also perform better than VAR under nonlinear data generation process; local projection may reduce the unavoidable misspecification which occurs in VAR. We compare the impulse responses obtained from a recursive VAR, a structure VAR, and local projection. We find that the central bank of Taiwan raises the interest rate after a positive shock of world interest rate. However, we do not find the same reaction after a positive domestic price shock. Moreover, if the central bank devalues domestic currency, the industry production raises in short run but the effect only lasts for ten months. We also find the by-product of devaluation - it raises the domestic price level in the long run.
