[en] ÂNGELO MURGEL: SINGULAR TRAJECTORY (1932-1939) / [pt] ÂNGELO MURGEL: TRAJETÓRIA SINGULAR (1932-1939)BERNARD CUNHA RODRIGUES 19 December 2016 (has links)
[pt] Dentro da trajetória profissional de Ângelo Murgel foi selecionado recorte
temporal caracterizado por sua afinidade com o Art Déco, aproximadamente entre
os anos de 1932 e 1939. Foram selecionados para estudo três obras projetadas
pelo arquiteto no referido período e modelo arquitetônico: Cine Theatro Brasil,
Hospital São Lucas e Brasil Palace Hotel. Do exame do contexto cultural
vivenciado por Murgel até sua formação, do estudo da conjuntura de anseio por
modernidade existente em Belo Horizonte especialmente durante a década de
1930 e da análise dos três projetos selecionados, pretende-se relacionar nosso
objeto de pesquisa, Ângelo Murgel, ao modelo de arquitetura Art Déco muito
difundido na capital mineira entre as décadas de 1930 e 1940. Sendo projetos de
um mesmo arquiteto, que se consolidou como o primeiro profissional a
desenvolver um projeto no estilo em Belo horizonte, o estudo é feito de maneira a
compreender a formação tanto de sua pratica projetual, contemplando a
apropriação das formas tradicionais e modernas, como também do seu discurso,
discutindo o aproveitamento das novas técnicas e tecnologias construtivas nas
construções. / [en] Within the professional career of Angelo Murgel was selected time frame

De la révolution lucasienne aux modèles DSGE : réflexions sur les développements récents de la modélisation macroéconomique / History of recent developments in macroeconomic modeling : from Robert Lucas to dynamic stochastic general equilibrium (DSGE) modelsSergi, Francesco 24 March 2017 (has links)
Ce travail propose une mise en perspective des pratiques de modélisation macroéconomique,depuis les travaux de Robert E. Lucas dans les années 1970 jusqu’aux contributions actuelles de l’approche dite d’équilibre général dynamique stochastique (DSGE). Cette mise en perspective permet de caractériser l’essor des modèles DSGE comme un compromis entre conceptions antagonistes de la modélisation : d’une part, celle de l’approche des cycles réels (RBC) et, d’autre part, celle de la nouvelle économie keynésienne. Pour justifier cette opposition, ce travail propose une reconstruction épistémologique de l’histoire récente de la macroéconomie, à savoir une analyse des différents critères qui définissent la validité et la pertinence d’un modèle. L’hypothèse de travail est qu’on peut identifier, pour chaque pratique de modélisation,trois critères méthodologiques fondamentaux : la validité interne (l’adéquation des hypothèses d’un modèle aux concepts aux formalismes d’une théorie), la validité externe(l’adéquation des hypothèses et/ou des résultats d’un modèle au monde réel, et les procédés quantitatifs pour évaluer cette adéquation) et le critère de hiérarchie (la préférence pour la validité interne sur la validité externe, ou vice versa). Cette grille de lecture, inspirée de la littérature sur les modèles en philosophie des sciences, permet d’apporter quatre contributions originales à l’histoire de la macroéconomie récente. (1) Elle permet de concevoir l’essor des modèles DSGE sans faire appel à l’explication proposée par l’historiographie produite par les macroéconomistes eux-mêmes,à savoir l’existence d’un consensus et d’un progrès technique exogène. Contre cette vision de l’histoire en termes de progrès scientifique, nous mettons en avant les oppositions méthodologiques au sein de la macroéconomie et nous illustrons l’interdépendance entre activité théorique et développement des méthodes statistiques et économétriques. (2) La thèse s’attaque au cloisonnement entre histoire des théories macroéconomiques et histoire des méthodes quantitatives. Grâce à sa perspective méthodologique, ce travail permet d’opérer la jonction entre ces deux littératures et de développer les bases d’une vision globale des transformations récentes de la macroéconomie. (3) La relecture méthodologique de l’histoire de la modélisation permet de mettre en évidence comment la condition de validité externe a représenté le principal point de clivage entre différentes conceptions de la modélisation. La question de la validité externe apparaît par ailleurs intrinsèquement liée à la question de l’explication causale des phénomènes, sur laquelle repose largement la justification de la modélisation comme outil d’expertise des politiques économiques. (4) Ce travail aboutit à une caractérisation originale de l’approche DSGE : loin de constituer une «synthèse» ou un consensus, cette approche s’apparente à un compromis, fragilisé par l’antagonisme méthodologique entre ses parties prenantes. / This dissertation provides a history of macroeconomic modeling practices from RobertE. Lucas’s works in the 1970s up to today’s dynamic stochastic general equilibrium (DSGE) approach. Working from a historical perspective, I suggest that the recent rise of DSGE models should be characterized as a compromise between opposing views of modeling methodology—on the one hand, the real business cycle (RBC) view, on the other hand, the new Keynesian view. In order to justify this claim, my work provides an epistemological reconstruction of the recent history of macroeconomics, building from ananalysis of the criteria defining the validity and the pertinence of a model. My assumption is that recent macroeconomic modeling practices can be described by three distinctive methodological criteria : the internal validity criterion (which establishes the consistency between models’ assumptions and concepts and formalisms of a theory), the external validity criterion (which establishes the consistency between the assumptions and results of a model and the real world, as well as the quantitative methods needed to assess such a consistency) and the hierarchization criterion (which establishes the preference for internal over external validity, or vice versa). This epistemological reconstruction draws primarily from the literature about models in the philosophy of science. My work aims to make four contributions to the history of recent macroeconomics. (1) To understand the rise of DSGE models without referring to the explanation providedby the macroeconomists themselves, who tend to think that macroeconomics evolved through theoretical consensus and exogenous technical progress. By distancing itself fromthis perspective, my work draws attention to the disruptive character of methodological controversies and to the interdependence between theoretical activity and the developmentof statistical and econometric methods. (2) To overcome the existing divide betweenthe history of macroeconomic theories and the history of quantitative methods. Throughits epistemological perspective, my work reconciles these two historiographies and specifiesthe basis for a comprehensive understanding of recent developments in macroeconomics.(3) To put the accent on the external validity condition as the main controversial issue separating different views of macro-modeling methodology. Furthermore, I illustrate how the debate about external validity is closely related to the problem of casual explanation and, finally, to the conditions for providing economic policy evaluation. (4) To characterize the DSGE approach: although DSGE models are often presented as a“synthesis”, or as a “consensus”, they are better described as a shaky compromise between two opposing methodological visions.

Etudes sur les équations de Ramanujan-Nagell et de Nagell-Ljunggren ou semblablesDupuy, Benjamin 03 July 2009 (has links)
Dans cette thèse, on étudie deux types d’équations diophantiennes. Une première partie de notre étude porte sur la résolution des équations dites de Ramanujan-Nagell Cx2+ b2mD = yn. Une deuxième partie porte sur les équations dites de Ngell-Ljunggren xp+ypx+y = pezq incluant le cas diagonal p = q. Les nouveaux réesultats obtenus seront appliqués aux équations de la forme xp + yp = Bzq. L’équation de Catalan-Fermat (cas B = 1) fera l’objet d’un traitement à part. / In this thesis, we study two types of diophantine equations. A ?rst part of our study is about the resolution of the Ramanujan-Nagell equations Cx2 + b2mD = yn. A second part of our study is about the Nagell-Ljungren equations xp+yp x+y = pezq including the diagonal case p = q. Our new results will be applied to the diophantine equations of the form xp + yp = Bzq. The Fermat-Catalan equation (case B = 1) will be the subject of a special study.

Zlepšení rozlišení pro vícečetné snímky stejné scény / SuperresolutionMezera, Lukáš January 2010 (has links)
Úkolem této diplomové práce je navrhnout vlastní metodu pro zvýšení rozlišení v obraze scény, pokud je k dispozici více snímků dané scény. V teoretické části diplomové práce jsou jako nejlepší metody pro zvýšení rozlišení v obraze vybrány ty, které jsou založeny na principech zpracování signálu. Dále jsou popsány základní požadavky metod pro zvýšení rozlišení v obraze při přítomnosti více snímků stejné scény a jejich typická struktura. Následuje stručný přehled těchto metod a jejich vzájemné porovnání podle optimálních kritérií. Praktická část diplomové práce se zabývá samotným návrhem metody pro zvýšení rozlišení v obraze, pokud je k dispozici více snímků této scény. První navržená metoda je naimplementována a otestována. Při testování této metody je však zjištěna její špatná funkčnost pro snímky scény s nízkým rozlišením, které vznikly vzájemnou rotací. Z toho důvodu je navržena vylepšená metoda pro zvýšení rozlišení v obraze. Tato metoda využívá při svém výpočtu robustních technik. Díky tomu je již vylepšená metoda nezávislá na rotaci mezi snímky scény s nízkým rozlišením. I tato metoda je řádně otestována a její výsledky jsou porovnány s výsledky první navržené metody pro zvýšení rozlišení v obraze. V porovnání výpočetních časů je lepší první navrhovaná metoda, avšak její výsledky pro obrazy obsahující rotace nejsou kvalitní. Oproti tomu pro obrazy, které vznikly pouze posunem při snímání scény, jsou tyto výsledky velice dobré. Vylepšená metoda je tedy využitelná zejména pro obrazy obsahující rotace. V závěru této práce je ještě navrženo jedno vylepšení, které by mohlo zlepšit výsledky druhé navrhnuté metody pro zvýšení rozlišení v obraze scény.

Essays on international capital flows and macroprudential oversightOsina, Nataliia January 2018 (has links)
This thesis presents three essays on the main determinants and regulations of international capital flows. The essays contribute to an ongoing significant debate among scholars and practitioners on what determines international capital flows by examining the following issues: Global liquidity, market sentiment and financial stability indices; Global liquidity and capital flow regulations; and Global governance and gross capital flows dynamics. In the first essay, we explore the main determinants of global liquidity, measured using cross-border claims of banks, and establish the link between a variety of financial stability indices and global liquidity. For a sample of 149 countries between 2000 and 2016, we find that Bloomberg Financial Stability Indices are more powerful in explaining global liquidity than FRED Financial Stress Indices and the Euro Area Systemic Stress Composite Indicator (CISS). Moreover, both market sentiment indices, namely the US Conference Board Leading Economic Index (LEI) and the US IBD/TIPP Economic Optimism Index are economically and statistically significant on cross-border bank flows. The research provides useful insights on what market sentiment and financial stability indices are better to employ for financial markets surveillance and as such practice of investment management. We argue that anyone interested in using financial stability indices as indicators of financial conditions and the level of financial stress would benefit from tracking several indices and not just one. The second essay examines the effectiveness of capital controls and macroprudential policies as ways to manage the volume of international capital flows, controlling for other determinants. The findings show that capital controls imposed on inflows generally prevail over controls imposed on outflows in reducing the magnitude of capital flows. The results are consistent with the pecking order theory on capital flows and are connected with the riskiness of different asset classes. For a sample of 112 countries over 2000 and 2016, we find that FX and/or countercyclical reserve (RR_REV) and general countercyclical capital buffer requirements (CTC), reserve requirement ratios (RR) and concentration limits (CONC) are the most effective macroprudential policies for managing countries' exposures to global liquidity fluctuations. Moreover, progress is being made to reduce the systemic risks created by systemically important financial institutions (SIFIs) using macroprudential policies. The results reflect recent developments in Basel III regulations and shed light on the effective calibration of capital flow regulations to country-specific circumstances. The final essay examines the link between global governance indicators and patterns of gross capital flows, controlling for other determinants. For a sample of 67 countries between 2000 and 2016, we contribute to explain the existence of the Lucas paradox (1990) on "why doesn't capital flow from rich to poor countries" and the Feldstein-Horioka puzzle (1980). The findings show that institutional quality rather than the effect of diminishing returns of capital is a key explanation for the Lucas paradox. Finally, we provide new evidence on the relationship between the multidimensional nature of financial development and gross capital flows. The findings show the importance and predominance of financial institutions versus financial markets in the dissemination of international capital flows across counties.

MPS – En sällsynt och svår sjukdom : En artikelserie om människor vars liv påverkas av den ovanliga sjukdomenDennerman, Katarina January 2006 (has links)
<p>Det var när Lucas Knies var dryga året som han fick sin diagnos – han lider av en svår ämnesomsättningssjukdom som bara fyra personer till i Sverige har. Sjukdomen är ärftlig och tillhör sjukdomsgruppen mukopolysackaridoser, MPS-sjukdomar. Läkarna har tidigare stått handfallna men forskningen har gått framåt och behandling för dessa sjukdomar håller på att utvecklas. De familjer som får beskedet att deras barn är svårt sjukt vill ofta ha kontakt med andra människor som befinner sig i samma situation. Informationsbehovet är stort och i juli 2005 startade MPS-föreningen för alla MPS-sjuka och deras familjer.</p>
