Local Convergence of Newton-type Methods for Nonsmooth Constrained Equations and Applications

Herrich, Markus 16 January 2015 (has links) (PDF)
In this thesis we consider constrained systems of equations. The focus is on local Newton-type methods for the solution of constrained systems which converge locally quadratically under mild assumptions implying neither local uniqueness of solutions nor differentiability of the equation function at solutions. The first aim of this thesis is to improve existing local convergence results of the constrained Levenberg-Marquardt method. To this end, we describe a general Newton-type algorithm. Then we prove local quadratic convergence of this general algorithm under the same four assumptions which were recently used for the local convergence analysis of the LP-Newton method. Afterwards, we show that, besides the LP-Newton method, the constrained Levenberg-Marquardt method can be regarded as a special realization of the general Newton-type algorithm and therefore enjoys the same local convergence properties. Thus, local quadratic convergence of a nonsmooth constrained Levenberg-Marquardt method is proved without requiring conditions implying the local uniqueness of solutions. As already mentioned, we use four assumptions for the local convergence analysis of the general Newton-type algorithm. The second aim of this thesis is a detailed discussion of these convergence assumptions for the case that the equation function of the constrained system is piecewise continuously differentiable. Some of the convergence assumptions seem quite technical and difficult to check. Therefore, we look for sufficient conditions which are still mild but which seem to be more familiar. We will particularly prove that the whole set of the convergence assumptions holds if some set of local error bound conditions is satisfied and in addition the feasible set of the constrained system excludes those zeros of the selection functions which are not zeros of the equation function itself, at least in a sufficiently small neighborhood of some fixed solution. We apply our results to constrained systems arising from complementarity systems, i.e., systems of equations and inequalities which contain complementarity constraints. Our new conditions are discussed for a suitable reformulation of the complementarity system as constrained system of equations by means of the minimum function. In particular, it will turn out that the whole set of the convergence assumptions is actually implied by some set of local error bound conditions. In addition, we provide a new constant rank condition implying the whole set of the convergence assumptions. Particularly, we provide adapted formulations of our new conditions for special classes of complementarity systems. We consider Karush-Kuhn-Tucker (KKT) systems arising from optimization problems, variational inequalities, or generalized Nash equilibrium problems (GNEPs) and Fritz-John (FJ) systems arising from GNEPs. Thus, we obtain for each problem class conditions which guarantee local quadratic convergence of the general Newton-type algorithm and its special realizations to a solution of the particular problem. Moreover, we prove for FJ systems of GNEPs that generically some full row rank condition is satisfied at any solution of the FJ system of a GNEP. The latter condition implies the whole set of the convergence assumptions if the functions which characterize the GNEP are sufficiently smooth. Finally, we describe an idea for a possible globalization of our Newton-type methods, at least for the case that the constrained system arises from a certain smooth reformulation of the KKT system of a GNEP. More precisely, a hybrid method is presented whose local part is the LP-Newton method. The hybrid method turns out to be, under appropriate conditions, both globally and locally quadratically convergent.

Essays on Economic Growth and the skill bias of technology

Voigtländer, Nico 28 May 2008 (has links)
Esta tesis doctoral es una colección de tres artículos. Los capítulos 1 y 2, co-autorados con Joachim Voth, investigan por qué Europa en 1700 ya era más rico que el resto del mundo y por qué Inglaterra fue el primer país en industrializarse. Encontramos que las dinámicas de la población, en lugar del crecimiento de la productividad, fueron los promotores más importantes del desarrollo económico de Europa Occidental durante la temprana edad moderna (1450-1700). Calibramos un modelo probabilístico para representar Inglaterra en 1700 y encontramos que ingresos iniciales más altos unidos a limitaciones de fertilidad aumentaron la probabilidad de industrialización. En el tercer capítulo, presento un nuevo hecho estilizado y analizo su contribución al sesgo del cambio tecnológico hacia los trabajadores más cualificados: El porcentaje de trabajadores cualificados en la producción intermedia está altamente correlacionado con la proporción de trabajo cualificado en la producción final. Esto genera un efecto multiplicador que refuerza la demanda de trabajo cualificado a lo largo de la cadena de producción. El efecto es importante, explica más de un tercio del aumento de la demanda de trabajadores cualificados en la industria manufacturera de EE.UU. / This dissertation is a collection of three essays. Chapters 1 and 2, co-authored with Joachim Voth, investigate the question why Europe in 1700 was ahead of the rest of the world and why England was the first country to industrialize. We find that population dynamics, rather than productivity growth, were the most important drivers for Western Europe to overtake China in the early modern period (1450-1700). We calibrate a probabilistic model to match England in 1700 and find that higher initial per capita incomes together with fertility limitation increased its industrialization probabilities. In the third chapter, I present a novel stylized fact and analyze its contribution to the skill bias of technical change: The share of skilled labor embedded in intermediate inputs correlates strongly with the skill share employed in final production. This delivers a multiplier that reinforces skill demand along the production chain. The effect is large, accounting for more than one third of the observed skill upgrading in U.S. manufacturing.

The institutionalization of multilevel politics in Europe

Yasar, Rusen January 2017 (has links)
This thesis addresses the question as to why multilevel politics is becoming an integral part of politics in Europe. Multilevel politics is conceptualized as a system which functions through a complex web of political relations within and across levels of decision making. The thesis argues that the rise of multilevel politics can be explained by its institutionalization in terms of the emergence, the evolution and especially the effects of relevant institutions. Based on a mixed-method research project, the influence of European institutions on subnational actors and the alignment of actor motives with institutional characteristics are empirically shown. The first chapter of the dissertation establishes the centrality of institutions for political transformation, examines the role of transnational and domestic institutions for multilevel politics, and contextualizes the research question in terms of institution-actor relations. The second chapter develops a new-institutionalist theoretical framework that explains the emergence, the evolution and the effects of the institutions, and formulates a series of hypotheses with regard to freestanding institutional influence, power distribution, material benefits and political identification. The third chapter outlines the mixed-method research design which addresses individual-level and institutional-level variations through a Europe-wide survey and a comparative case study. The fourth chapter on survey results shows generally favourable views on multilevel politics, and strong associations of these views with the independent variables under scrutiny. The fifth chapter specifies a multivariate model which includes all posited variables and confirms the majority of the hypotheses. Therefore, the new-institutionalist argument is broadly confirmed, while there is relatively weak evidence to sustain sociological explanations. The final chapter compares the Committee of the Regions and the Congress of Local and Regional Authorities, and examines the institutional characteristics which correspond to the hypothesized variables. It is then concluded that the two institutions share several overarching similarities, and display complementarity in other aspects.

There is a great need to justify the investments in this area and an expectation to promote superior performance from the use of IT resources and capabilities. Therefore, it is important to clarify the IT value and role in the firms. Changes and high velocity marketing contexts are major challenges to environmental organizations. In this sense, the IT use decisions should be able to mobilize IT resources and capabilities to respond to organizational environment changes and IT performance should be evaluated for their contribution to business processes, rather than to try linking on a direct relationship to overall performance in which many variables obscure the real IT value. This study is based on resource-based view of the firm (RBV), dynamic capabilities and complementarities of organizational resources. Two guidelines are proposed for IT use decisions. The first one is driven by IT reconfigurability and complementary capabilities. The second one is driven by IT infrastructure, personal and partnerships assets. The performance is evaluated by the IT use competences in terms of aspects of their functionality and market requirements relative to IT process. This empirical investigation assessed its goal considering a sample of professionals responsible for IT decision making and planning in Brazilian organizations. Datas were analyzed through partial least squares path modeling (PLS-PM). The main results indicated strong and significant effects of capabilities-oriented IT use decisions over their assets-oriented. It was revealed that personal assets-oriented IT use decisions are the ones that influence the performance of IT funcionality competences. Finally, it was evident the importance of IT use decisions treatment as a dynamic capability even without the influence of the moderating effect of the turbulence of organizational environment. The main scholarly contributions are filling the gap of decisions involving the use of IT, its performance on process level within the organizational context of Brazil, and theoretical use of the resource-based view of the firm and dynamic capabilities as background able to promote IT value. Among the main contributions to professional practices stands out to take in account of reconfigurability and complementarity capability of IT resources in their use decisions along with other organizational resources so that they can get a better process performance. The study shows promising future researches in assessing the IT value and development of measures and constructs more appropriate to its evaluation. / O objetivo principal do estudo é verificar os efeitos das decisões do uso da tecnologia da informação (TI) no seu desempenho. Existe uma grande necessidade de justificar os investimentos realizados nessa área e uma expectativa de promover um desempenho superior com o uso dos recursos e capacidades da TI. Portanto, é importante esclarecer o seu valor e o seu papel nas organizações. Mudanças e contextos mercadológicos de rápidas transformações são grandes desafios ao ambiente das organizações. Nesse sentido, as decisões do uso da TI devem ser capazes de mobilizar os recursos e capacidades da TI para responder às mudanças do ambiente organizacional e o desempenho desse uso deve ser avaliado pela contribuição aos processos de negócio, ao contrário de insistir numa relação direta ao desempenho geral em que muitas variáveis ofuscam o real valor da TI. O estudo fundamenta-se na visão baseada em recursos da firma, nas capacidades dinâmicas e na complementaridade dos recursos organizacionais. São propostas duas orientações para as decisões do uso da TI. A primeira orientada pelas capacidades de reconfigurabilidade e complementaridade da TI. A segunda orientada pelos ativos de infra-estrutura, pessoal e parcerias. O desempenho é avaliado pelas competências do uso da TI em relação aos aspectos de sua funcionalidade e de mercado, em nível das exigências do seu processo. O estudo avaliou empiricamente seu objetivo numa amostra de profissionais responsáveis pela tomada de decisão e planejamento de TI em organizações brasileiras. Os dados foram analisados através da modelagem de caminhos por mínimos quadrados parciais. Os principais resultados apontaram fortes e significantes efeitos das decisões do uso da TI orientadas pelas capacidades sobre as decisões orientadas pelos ativos de TI. Revelou-se que as decisões orientadas pelos ativos de pessoal são as únicas que influenciam o desempenho das competências de funcionalidades da TI. Por último, foi evidenciado a importância do tratamento das decisões do uso da TI como uma capacidade dinâmica mesmo sem influência do efeito moderador da turbulência do ambiente organizacional. As principais contribuições acadêmicas são o preenchimento da lacuna que envolve as decisões do uso da TI, seu desempenho em nível de processo dentro do contexto organizacional brasileiro e o usoteórico da visão baseada em recursos da firma e das capacidades dinâmicas como pano de fundo capaz de promover o valor da TI. Dentre as principais contribuições para a prática profissional destaca-se a consideração das capacidades de reconfigurabilidade e complementaridade dos recursos de TI nas decisões do seu uso junto aos demais recursos organizacionais para que se possa obter um melhor desempenho dos processos. O estudo aponta pesquisas futuras promissoras na avaliação do valor da TI e no desenvolvimento de medidas e construtos mais apropriados para sua avaliação.

L'obligation de coopération dans le statut de Rome : analyse critique du respect des engagements internationaux devant la cour pénale internationale. / The obligation of cooperation in the Status of Rome : analysis criticizes some respect for the international commitments in front of the International Criminal Court

Ndiaye, Yaram 27 September 2012 (has links)
A l’instar des juridictions qui l’ont précédé dans la répression des crimes internationaux, la Cour pénale internationale a besoin de la coopération des Etats pour exister. C’est une condition d’effectivité de l’action de la Cour qui se traduit par la participation des Etats à la procédure pénale internationale et par l’harmonisation des législations nationales. Toutefois, en dépit de son affirmation dans le Statut, les Etats parties exécutent difficilement l’obligation de coopération. Ces difficultés s’observent tant au niveau de leur participation à la procédure initiée par la Cour que dans l’exercice de la justice au niveau national. De fait, pour un respect des engagements internationaux devant la Cour, l’institution doit surmonter l’obstacle de la souveraineté nationale. Pour atteindre les objectifs fixés, elle doit amener les Etats à dépasser les critères traditionnels de compétence dans le domaine pénal et à taire les résistances souverainistes en la matière. C’est seulement à ce titre qu’elle peut être fonctionnelle, en opposant aux Etats une conception plus étendue de la justice pour laquelle ils se sont engagés. / Following the example of the jurisdictions which preceded her in the repression of the international crimes, the International Criminal Court needs the cooperation of States to exist. It is a condition of effectiveness of the action of the Court that is translated by the participation of States in the international criminal procedure and by the harmonization of the national legislations. But in spite of its assertion in the Status, States execute with difficulty the obligation of cooperation. These difficulties observe as long at the level of their participation in the procedure in front of the Court that in the exercise of the justice at the national level. Actually, for a respect for the international commitments in front of the Court, the institution has to surmount the obstacle of the national sovereignty. To reach the fixed objectives, she has to bring States to exceed the traditional criteria of skill in the penal domain and to keep silent about the resistances of states on the subject. It is only as such that she can be functional, by setting to States a more vast conception of the justice for which they made a commitment.

Analyse du fonctionnement des performances des associations blé dur-pois d'hiver et blé dur-féverole d'hiver pour la conception d'itinéraires techniques adaptés à différents objectifs de production en systèmes bas-intrants / Analysis of the functioning and efficiency of durum wheat - winter pea and durum wheat - winter faba bean intercrops in order to design cropping systems

Bedoussac, Laurent 29 September 2009 (has links)
Les associations d'espèces sont définies comme la culture simultanée d'au moins deux espèces sur la même parcelle pendant une période significative de leur croissance. Ce système permettrait d'améliorer l'utilisation des ressources du milieu (eau, azote, lumière…) et ainsi d'augmenter le rendement et la qualité des grains par rapport aux cultures monospécifiques. L'objectif de notre travail était d'analyser le fonctionnement et d'évaluer la performance des associations blé dur - pois d'hiver et blé dur - féverole d'hiver pour aider à la conception d'itinéraires techniques adaptés à différents objectifs de production. Pour cela nous avons testé, au cours de trois années d'expérimentations, différentes combinaisons de variétés de blé dur, disponibilités en azote, structures de couverts et densités de plantes. Nos résultats ont confirmé l'intérêt de ces systèmes pour améliorer le rendement et la teneur en protéines du blé dur comparativement aux cultures monospécifiques mais également pour la réduction des ravageurs, maladies et de l'enherbement dans certaines conditions. Ces systèmes sont ainsi particulièrement bien adaptés aux situations à faible disponibilité en azote en raison de la complémentarité entre céréale et légumineuse pour l'utilisation de l'azote (minéral du sol et fixation symbiotique) mais aussi pour la captation de l'énergie lumineuse. In fine, ce travail a permis de proposer des prototypes d'itinéraires techniques d'associations adaptés à différents objectifs de production, grâce notamment à l'analyse dynamique des compétitions et complémentarités entre espèces au sein du couvert et en particulier de l'élaboration du rendement du blé dur en association. / Intercropping is the simultaneous growing of two or more species in the same field for a significant period. Such systems are known to use available resources (water, light, nitrogen…) more efficiently than their corresponding sole crops and consequently to increase yield and grain protein concentration particularly in low N input systems. The aim of our work was to analyse the functioning of durum wheat - winter pea and durum wheat - winter faba bean intercrops. A 3-year field experiment was carried out with different fertilizer-N levels, wheat cultivars and plant densities. The intercrop efficiency was studied in order to further design low inputs cropping systems for specific objectives. Our results confirm that intercropping is more suited to low-N-input systems because it takes advantage of complementary N sources (soil mineral N and N2 fixation) and light use between species of the intercrop. Thus, intercrops were more efficient than sole crops for yield, they increased durum wheat grain protein concentration and in certain cases reduced weeds, pests and diseases. Finally, our work indicates that intercrops can be optimized for specific objectives by the choice of crop species, cultivars, N fertilization and plant densities in order to maximize resource capture and minimize competition. Indeed, intercrop efficiency is determined by the complementary resource use between the two species as well as the relative strength of the intra- and interspecific dynamic competitive interactions.

Les méthodes numériques de transport réactif / Numerical methods for reactive transport

Sabit, Souhila 27 May 2014 (has links)
La modélisation du transport réactif du contaminant en milieu poreux est un problème complexe cumulant les difficultés de la modélisation du transport avec celles de la modélisation de la chimie et surtout du couplage entre les deux. Cette modélisation conduit à un système d'équations aux dérivées partielles et algébriques dont les inconnues sont les quantités d'espèces chimiques. Une approche possible, déjà utilisée par ailleurs, est de choisir la méthode globale DAE : l'utilisation d'une méthode de lignes, correspondant à la discrétisation en espace seulement, conduit à un système différentiel algébrique (DAE) qui doit être résolu par un solveur adapté. Dans notre cas, on utilise le solveur IDA de Sundials qui s'appuie sur une méthode implicite, à ordre et pas variables, et qui requiert à chaque pas de temps la résolution d'un grand système non linéaire associé à une matrice jacobienne. Cette méthode est implémentée dans un logiciel qui s'appelle GRT3D (Transport Réactif Global en 3D). Le présent travail présente une amélioration de la méthode GDAE, du point de vue de la performance, de la stabilité et de la robustesse. Nous avons ainsi enrichi les possibilités de GRT3D, par la prise en compte complète des équations de précipitation-dissolution permettant l'apparition ou la disparition d'une espèce précipitée. En complément de l'étude de la méthode GDAE, nous présentons aussi une méthode séquentielle non itérative (SNIA), qui est une méthode basée sur le schéma d'Euler explicite : à chaque pas de temps, on résout explicitement l'équation de transport et on utilise ces calculs comme données pour le système chimique, résolu dans chaque maille de façon indépendante. Nous présentons aussi une comparaison entre cette méthode et l'approche GDAE. Des résultats numériques pour deux cas tests, celui proposé par l'ANDRA (cas-test 2D) d'une part, celui proposé par le groupe MoMas (Benchmark "easy case") d'autre part, sont enfin présentés, commentés et analysés. / Modeling reactive transport of contaminants in porous media is a complex problem combining the difficulties of modeling the trasport with those of modeling the chemistry and especially the coupling between the two .This model leads to a system of partial differential equations and algebraic equations whose unknowns are the quantities of chemical species. One approach , already used elsewhere , is choosing the global DAE method : using the method of lines, discretization in space only, leads to a differential algebraic system (DAE ) to be solved by a suitable solver . In our case , the solver IDA Sundials relies on an implicit method, order is used but not variables, and requires at each time solving a large nonlinear system associated with a Jacobian matrix . This method is implemented in a software called GRT3D (Global Reactive Transport in 3D). This paper presents an improved GDAE method , from the standpoint of performance, the stability and robustness. We have enriched the possibilities of GRT3D , by taking full account of the equations of dissolution – precipitation for the appearance or disappearance of precipitated species. In addition to the study of the GDAE method, we also present a non-iterative sequential method ( SNIA ) which is a method based on the explicit Euler scheme : at each time step, we explicitly solve the transport equation and we use these calculations as data for the chemical system which is resolved in each cell independently. We also present a comparison between this method and GDAE approach . Numerical results for two test cases , one proposed by ANDRA ( 2D test case ) on one hand and one proposed by the group MOMAS ( Benchmark "easy case" ) on the other hand, are finally presented , discussed and analyzed.

La mixité d'usages verticale depuis une perspective habitante : étude de cinq produits immobiliers résidentiel et commercial montréalais récents

Deborne, Elise 09 1900 (has links)
La mixité d’usages est aujourd’hui, un principe clé de planification urbaine, considérée essentielle à la qualité, vitalité et durabilité des milieux urbains. Mais en pratique, celle-ci sert encore et surtout l’intensification – notamment sur un plan vertical – des secteurs de ville-centre au marché du logement tendu et foncier rare ; et même dans ce contexte, se heurte à une barrière culturelle. Il s’avère donc opportun de se pencher sur les avantages et contraintes – depuis une perspective habitante – de la mixité d’usages verticale résidentielle et commerciale (fonctions généralement considérées comme complémentaires et compatibles, et fréquemment combinées à l’échelle du bâtiment), et d’examiner les conditions dans lesquelles ces expériences sont manifestées. La recherche interroge, au cours d’entrevues semi-dirigées, dix résidents et six commerçants de cinq produits immobiliers à mixité d’usages verticale résidentielle et commerciale montréalais récents. L’analyse met en évidence des retombées en termes de proximité aux commerces et services, vitalité économique, qualité du cadre bâti, vitalité locale, sentiment de sécurité et convivialité ; et discerne en parallèle, des conflits d’usages (direct), conflits d’échelle, conflit d’intérêts (indirect), et contraintes d’espace et d’usage. La recherche illustre une articulation entre échelles du produit immobilier et locale ; la difficile mise en œuvre d’une approche limitée à l’arrimage d’usages compatibles ; l’enjeu d’une intégration d’usages variés dans la capitalisation de synergies et prévention des conflits et contraintes ; et considère à cet égard l’opportunité que représente le règlement sur les usages conditionnels au Québec. Elle souligne également dans l’intégration en harmonie d’usages variés, l’importance après-coup, de la gestion du développement opérée. / Mixed use has become a key planning principle, promoted as essential for urban quality, vibrancy, and sustainability. However, in practice, mixed use remains mostly a tool for the intensification – notably on a vertical dimension – of inner-city districts with tight housing market and land scarcity. Still, in that context, it encounters cultural barriers. It is therefore appropriate to examine the opportunities and issues – from the perspective of occupiers – in vertically mixed residential and commercial development (functions usually considered as complementary and compatible, and frequently combined at the building scale), and the conditions in which such experiences arise. To address this, semi-structured interviews were conducted with ten residents and six retailers of five new vertically mixed residential and commercial properties located in Montreal. Benefits in terms of proximity to retail stores and services, economic vitality, quality of the built environment, vibrancy, perceived security and community life have been highlighted. Land-use conflicts (direct), conflicts of scale, conflict of interest (indirect), and space and use constraints have been discerned from the cross-case analysis. The study illustrates a dialectic relation between building-complex and local scales; the difficult task of implementing a mix limited to compatible functions; and the challenge of integrating various uses to capitalize on synergies and prevent conflict and constraints. In this last respect, the study considers the opportunity presented, in Quebec, by the by-law on conditional use. It also points out the significance afterwards of the property management in the harmonious integration of various uses.

Local Convergence of Newton-type Methods for Nonsmooth Constrained Equations and Applications

Projevy antifeminismu v současném učení římskokatolické církve / Manifests of antifeminism in contemporary teaching of the Roman Catholic Church

Langhammerová, Gabriela January 2020 (has links)
The diploma thesis Antifeminism in Contemporary Teaching of the Roman Catholic Church examines the mechanisms which shape the identity of women in Roman Catholic teachings. This is the starting point for the subsequent constitution of gender order, i.e. the way the relationship between man and woman is constructed, and in which woman is subordinated to man. To support the subordinate position of women, Roman Catholic theology implemented theory of complementarity into its teachings. This inequality provides an important underpinning of gender-based violence. Feminist movement and feminist theology, such as that of Mary Daly brought new analytical tools in the 1960s and 1970s to understand the functioning of the social mechanisms that lead to women's subordination. These tools are, in particular, feminist critique and perspective, critique of power relations and of androcentrism, and a specifically feminist understanding of woman's identity. The Istanbul Convention, with its perspective that rejects inequality, promotes criticism of power relations and describes violence against women as gender-based violence, is conceptually in accordance with the methods and goals of the feminist movement as well as with democratic principles. In particular, it agrees with them on the issue of gender-based...
