Full textAbstract:
La première partie consiste en une étude taxonomique de l'espèce Prunella vulgaris. Différentes méthodes numériques appliquées à des populations sauvages du Sud-Ouest de la France permettent de séparer des groupes de populations grâce à des caractères discriminants et de déterminer leur valeur toxonomique. La culture expérimentale permet de préciser l'influence du milieu sur les caractères morphologiques. La deuxième partie est consacrée à l'étude de l'hybride entre P. Vulgaris et P. Laciniata. Après une description des différentes formes sauvages, la mise en culture de certaines permet d'étudier leur descendance et d'obtenir des lignées pures. L'évolution naturelle au cours des années successives est retracée pour quelques stations. Dans la troisième partie, nous avons recherché les mécanismes assurant le maintien des deux espèces parentes, compte tenu de leur facilité à s'hybrider. L'étude phytosociologique montre qu'il existe un certain isolement écologique entre les deux espèces. Les diverses modalités de fécondation et la phénologie sont ensuite envisagées sur des populations cultivées des deux espèces parentales et hybrides. Enfin, l'hybridation expérimentale nous a permis de reproduire des types naturels et de comparer la fertilité et les caractères phénologiques des hybrides suivant le sens du croisement.

Full textAbstract:
Cette thèse porte sur l'étude de classes d'opérateurs. On étudie principalement deux familles différentes de classes d'opérateurs.- Les premières classes étudiées sont des classes d'opérateurs sur des espaces de Hilbert généralisant les classes $C_{ho}$ de Sz.Nagy et Foias.Pour $(ho_n)_n$ une suite de nombres complexes non-nuls, on définit la classe $C_{(ho_n)}(H)$ comme l'ensemble des opérateurs $T in mathcal{L}(H)$ qui possèdent une $(ho_n)$-dilatation : il existe un espace de Hilbert K et un opérateur unitaire $U in mathcal{L}(K)$ avec $H subset K$ tels que $T^n=ho_n P_H U^n|_H$ pour tout n $geq$ 1 ($P_H in mathcal{L}(K)$ étant la projection orthogonale de K sur H). Ces classes peuvent être associées à une fonction holomorphe $f_{(ho_n)}$ ainsi qu'à une quasi-norme $w_{(ho_n)}$. Nous utilisons les liens entre ces trois objets pour caractériser, décrire, et donner plusieurs propriétés spectrales sur les opérateurs contenues dans ces classes. Nous exhibons de même des relations entre plusieurs classes de cette forme, nous généralisons des résultats connus pour les classes $C_{(ho)}$, et donnons divers exemples et situations offrant des comportements différents du cas $C_{(ho)}$. Nous apportons aussi une nouvelle vision géométrique sur un résultat entre des quasi-normes $w_{ho}$, et nous étendons des calculs de $w_{ho}(T)$ pour des opérateurs T annulés par un polynôme de degré deux.- La deuxième partie principale de cette thèse concerne les classes de L^p-projections. Une L^p-projection sur un espace de Banach X, pour $1leq p leq +infty$, est une projection P qui vérifie $ |f|_X = |(|P(f)|_X, |(I-P)(f)|_X) |_{ell_{p}}$ pour tout f dans X. Cette relation est une version L^p de l'égalité $|f|^2=|Q(f)|^2 + |(I-Q)(f)|^2$, vérifiée pour les projections orthogonales dans les espaces de Hilbert.Nous nous intéressons aux relations entre les L^p-projections sur un espace de Banach X et celles sur un sous-espace F, sur un quotient X/F, ou sur un sous-espace de quotient G/F. Des caractérisations complètes sont apportées pour des espaces de Banach vérifiant quelques propriétés additionnelles, et selon la valeur de p.Nous introduisons aussi la notion de L^p-projection maximale pour X, c'est-à-dire des L^p-projections définies sur un sous-espace G de X qui ne peuvent pas être étendues comme L^p-projections sur un sous-espace plus grand, et étudions leurs propriétés, en particulier dans le cas de la dimension finie.Nous obtenons de même une caractérisation des L^{infty}-projections sur tous les espaces L^{infty}(Omega) via de nouvelles méthodes, en généralisant ainsi les résultats connus à ce sujetThis thesis focuses on the study of classes of operators. Two different families of classes of operators are mainly studied.- The first classes we study are classes of operators on Hilbert spaces that generalize the classes $C_{ho}$ of Nagy and Foias. For $(ho_n)_n$ a sequence of non-zero complex numbers, we define the class $C_{(ho_n)}(H)$ as the set of operators $T in mathcal{L}(H)$ that are said to possess a $(ho_n)$-dilation: there exists a Hilbert space K and a unitary operator $U in mathcal{L}(K)$ with $H subset K$ and $T^n=ho_n P_H U^n|_H$ for every $n geq 1$ ($P_H in mathcal{L}(K)$ being the orthogonal projection from K onto its closed subspace H). These classes can be associated with an holomorphic map $f_{(ho_n)}$ as well as a quasi-norm $w_{(ho_n)}$. These three objects are tied together and we use them to characterize, describe, and give several spectral properties of operators belonging to this class.We give multiple relationships between multiple classes of this form, generalize many results that were known for classes $C_{(ho)}$, and give several examples and cases that exhibit new behaviours. We also bring a new geometric meaning behind a relationship between quasi-norms $w_{ho}$ and extend the computations of $w_{ho}(T)$ for operators T that are zeroes of a degree two polynomial.- The second main part of our study concerns classes of L^p-projections.An L^p-projection on a Banach space X, for $1leq p leq +infty$, is an idempotent operator P satisfying $ |f|_X = |(|P(f)|_X, |(I-P)(f)|_X) |_{ell_{p}}$ for all f in X. This is anL^p version of the equality $|f|^2=|Q(f)|^2 + |(I-Q)(f)|^2$, valid for orthogonal projections on Hilbert spaces.We are interested into relationships between L^p-projections on a Banach space X and L^p-projections on a subspace F, on a quotient X/F, or on a subspace of a quotient G/F. These questions are given an answer on Banach spaces with additional properties, depending on the value of p.We also introduce a notion of maximal L^p-projections for X, that is L^p-projections defined on a subspace G of X that cannot be extended to L^p-projections on larger subspaces, and study their properties, especially on finite dimensional Banach spaces. A characterization of L^{infty}-projections on every space L^{infty}(Omega) is obtained as well using new methods, generalizing previously known results

Bianco, Marco <1982>. "Flexibility and firm value: the role of inventories." Doctoral thesis, Alma Mater Studiorum - Università di Bologna, 2015. http://amsdottorato.unibo.it/7012/.
Full textAbstract:
In the present thesis I study the contribution to firm value of inventories management from a risk management perspective. I find a significant contribution of inventories to the value of risk management especially through the operating flexibility channel. In contrast, I do not find evidence supporting the view of inventories a reserve of liquidity. Inventories substitute, albeit not perfectly, derivatives or cash holdings. The substitution between hedging with derivatives and inventory is moderated by the correlation between cash flow and the underlying asset in the derivative contract. Hedge ratios increase with the effectiveness of derivatives. The decision to hedge with cash holdings or inventories is strongly influenced by the degree of complementarity between production factors and by cash flow volatility. In addition, I provide a risk management based explanation of the secular substitution between inventories and cash holdings documented, among others, in Bates et al. (2009), Journal of Finance. In a sample of U.S. firms between 1980 and 2006, I empirically confirm the negative relation between inventories and cash and provide evidence on the poor performance of investment cash flow sensitivities as a measure of financial constraints also in the case of inventories investment. This result can be explained by firms' scarce reliance on inventories as a reserve of liquidity. Finally, as an extension of my study, I contrast with empirical data the theoretical predictions of a model on the integrated management of inventories, trade credit and cash holdings.

The main goal of this project is to fill the potential of the place, that is hidden behind the church wall. A proposal that will benefit not only the place itself but also the village community and visitors. A project that revives the spirit of the place but preserves its intimate atmosphere. The design itself includes a bistro, an art gallery, accommodation with sauna and a wine gallery. Between all of this is a Provence-style garden.

Full textAbstract:
The theme of the development of the existing sports grounds was dealt with Based on a number of analyzes, visits to the site and communication with the community management, the theme of the development of the existing sports grounds was dealt with. The whole territory is up to a football field in a very maintained conditions. There are two smaller accommodation facilities, which are seasonally used mainly by schools in nature and other students, but their condition is quite unsatisfactory. The soccer field, which is the only one maintained, belongs to the existing base of soccer players - the dressing room with the clubhouse. Their condition is also somewhat aggravated. In the current spatial plan, the whole proposed area is at the interface of two areas, the first is the area of sport and individual recreation and the second is the area to be examined. Urban design is based on the location of the existing soccer field and the preservation or improvement of existing links to the surrounding area. Most of the paved areas will be overtaken. Part of the design of the development of sports activities in the village was also to find a possible solution for parking for tourists, for which there is no free space in the village. The chosen location is advantageous in that, when a parking lot will be created, it will be created near the main entrance to the village on road II. Cl. No. 420 from Hustopeče through the village. Architectonically, but also conceptually, the construction is based on the economic possibilities of the municipality, the possibilities of variability of the solution and especially of the possibilities of staging construction. The result are two buildings. One main, replacing the background of spccer players, creates the conditions for year-round training in the new gym, for going to fitness, while part of the building is a platform for the soccer field. The second building is an accommodation that replaces the existing unsatisfactory buildings. Architecturally, they are masses that are greatly affected by the modules. The building structure and the facilities of the sports hall are structurally designed from standardized modular systems, steel containers that are interconnected to create an unusual spectacle. The area of the gym is defined by a reinforced concrete skeleton. Both buildings are covered with gold anodized sheet metal, which is profiled similarly to the peripheral walls of the containers. At the same time, the object was to create year-round sports grounds that are accessible to the general public and youth.

The aim of the thesis is to define the vision (in concrete proposals) for the functioning of community, socio-social, leisure and other activities in the village. The vision as such emerged on the basis of analyzes already in the last semester, on its basis, we come to the solution of a partial project, which should show the municipality how to go and why. Representatives and residents of Strachotín have for a long time been considering certain steps, construction works of varying extent, which would strengthen the population, their possibilities in using the potential of the place (wine, tourism) and the village returned the lost face.There is only a small distance between the village and the end of the village in the direction of Pálava, but there is an important urban area - the surroundings of the church - which is historically very important and it hides its potential. In my work, I have commissioned him to uncover it and try to inspect what she can offer. Not only for tourists, but also for locals.

The project deals with the design of the wine gallery and community center in smaller wine-growing village Strachotín, which is situated in the beautiful landscape under the hills, called "Pálavské vrchy", and also is on the edge of the magnificent waterwork - "Novomlýnské nádrže". The construction of the wine gallery and the community center is designed in the historical structure of the village, near the gothic church. The project follows up the analytical part, which dealt with the vision for the future development of the village Strachotín. The vision, which after thorough examination of the village included seventeen interventions of small or larger urban character, which would be beneficial for the development of the village and surroundings.

The house is located in a quiet part of Strachotín. The plot itself is now used as agricultural land. The bio corridor belt creates a natural dominance around the area and ensures safe drainage of water during torrential rains. The concept is based on a wide range of services and care. The home for seniors will become part of the life of all seniors in the village and nearby. Supporting home-based autonomy allows seniors to live in their own home and only use the services that are available. Visits and social activities are a matter of course. Accommodation in the house itself will preferably be provided to seniors who require constant care. The operating standard of the home is designed to a very good standard. The home offers a barrier-free environment, single or double rooms. Meeting rooms are an important part of the house, along with a garden and bathing biotope. Separate living from operation guarantees a high level of privacy and allows direct contact with the garden.

Full textAbstract:
The diploma thesis follows the project of the pre-diploma, in which detailed analyzes of the potential of the village were made, from which it follows that the most important place that the village needs to revive for further development is the village square itself. In the current state, a cluster of buildings is built on a clearly defined area of the village, which brings chaos and confusion to the urban structure. The building of the municipal office stopped communicating through the building of the former elementary school. The area between buildings, formerly designed for local residents to hold festivals, now serves as a handling yard. The aim of the work is to clean the area of the village, to restore its original lost character and to add the urban structure to a building that will serve both local inhabitants and tourist visitors.

Full textAbstract:
The theme of the diploma thesis is based on conclusions of the pre-diploma thesis which tried to find lost potential of the village Strachotín and outline its possible development. Strachotín is located in a major wine region. Therefore, the potential of the municipality is mainly in wine, tradition and tourism. The stragedy builds on these potentials and creates two main themes. I live, I discover. The living factor represents inhabitants of Strachotín and the possibility of housing, work and recreation. The discovering factor represents traditions and tourism. The key theme becomes a village square. This is primarily a place for local residents, but also a place for the municipality to represent and support tourism. The village square is the most important part of the village, but the current state of affairs is not the case. Village square lost its identity thanks to inappropriate placement of objects and their functional use. The design tries to clean the village square from objects that are not functionally and aesthetically suitable. Objects that remain in the proposal are a municipal house and former school. They have a historical position here. The proposal adds a new object that combines and complements functions that have been missing or lost in the village in the original solution. The newly created public space creates not only a place for the inhabitants of Strachotín, but also a new tourist destination.

Full textAbstract:
The history of Strachotín, as we know it today, started yet before the year of 1300. Its urbanist structure remained relatively the same untill the 2nd third of the 18th century, nor did the number of houses change. The structure of the main square has been conserved in its original form. The important solitary buildings standing in the centre of the main square were the buildings of the Municipal House and the former School, the social services house nowadays (library, physician, hairstylist, post office). By gradually adding technical facilities and warehouses that have grown into an extended construction with residential units and a pub, all of them carried out on top of the original Municipal House, the result is a „cluster“ of virtually zero architectural and urbanist qualities. The consequential effect brings diminishing of the significance of the town centre as a common place – res publica. The main square ought to be understood as a central point of the town, a meeting point, a place for reunions. A place of information exchange, sharing and confrontation of various opinions. My objective has been to keep the current range of services offered and bring back the town´s lost identity and symbolics. Buildings constructed at the centre of the main square often carry a solitary character and Strachotín is therefore no exception. I consider this aspect as an essential one. The key feature has been splitting the functions and a convenient interconnectedness of the businesses within. The need for a new hall and a space for the community life has been put to life in the form of a building added to the former school, where now you can find an open complex of a community house, including an information centre, library, a club-room and services, such as the hairdressers´ and the physician´s office. I regard connecting the municipal hall and the pub together as the most convenient/ effective solution within the Municipal House. I have marked three functional areas within the public space of the main square by respecting the two current solitary buildings. The centre is represented by the „piazzetta“ - the paved area, I have conserved the park-like feature of the southern part with its grassy area, and for the northern part, I have proposed a orchard layout of the area including a childrens´ playground.

Full textAbstract:
In search of the genius loci - the spirit of the place we can use the principles of phenomenology applied to the landscape, architecture. With this approach we are able to describe the abstract phenomena and processes in the landscape. We are looking for the character of places, places make landscape. By attempting to delimit, define the character of the place, we are able to grasp the landscape, the world. Landscape can be divided into three species, assessing character, clarity, scale, presence of water, structure, identity: romantic, classical, cosmic. Based on the analytical pre-diploma thesis, I select the "triangle" site between the dykes as suitable for minor intervention in the form of a new building of cultural and tourist importance for the village of Strachotín and its surroundings. Functions respond to the need of strengthen the identity and uniqueness of the place, the village in the countryside, the position of the township in the wider area. This is where the tension, the potential, the force that needs to be used are contained. There are two landscapes on the dyke, cosmic and classical. There is a scale change here. The water scenery is a purely technical matter, the dam is a human creation, the dyke is a technology that allows water to be retained. On the other hand, it is a natural, classical landscape that gives life to the people who settled there years ago and built a village for themselves. The phenomenon of water-water surface of the reservoir, earth-landscape and air-sky are encountered on the edge. The approach to the village itself is symbolic, along the dam, on the road, the curve of hills with a view in the back plan, the central plan completes the walls of the trees that surround the village. The dominant feature of the church's tower verticals. In order to exploit the potential of the dam as a landscape interface, it is possible to create an object or modify the site itself. However, it can not ideally compete with the already created. The church tower will always symbolize the relationship of the spiritual and secular, imaginary connection with heaven, not the goal of trying to overcome this dominance. The goal is to engage organically, but not to go, to take advantage of the unique moment of sight, awareness of the place.

The aim of the project is to design a public building in the place, where phenomena of Pálava mountains, reflecting water surface and wine tradition meet. It is right in the area of Strachotín village. Project is trying to harness the power of these qualities to create a special attractive house. But also, the house is showing the viewer new perspective on these entities, which would not be seen without it. The location and concept of this wine house is strengthening the link between village and Pálava reflected in water. Therefore, the main part of interior is oriented exactly on the axis between these two poles. Secondarily, house contains the small museum of local history. In terms of technical aspects, we are dealing with the floating house, which is not affecting the building of dyke in no way.

Strachotín is a village on the edge, not just from geological point of view, but in the sense it´s next development too. Currently it´s main problem is, that it does not offer anything specific to become interesting for turists. There are not the best wine, architecture, accomodation, catering or public services. What it does have is undoubtedly the best view of Palava massif. It is not used at all and that was the main reason that led me to think of building at the pier so this attribute could be finally used for further development of this village. For this purpose i chose the object gallery of wine which is missing here and is also welcomed by it´s citizens.

Nous étudierons également les fonctions dont le domaine est les p-adiques et les distributions p-adiques. Ensuite, nous verrons les notions de base sur les formes modulaires et nous présenterons leur fonction L complexe. Dans le chapitre 2, nous construirons une distribution p-adique µf attachée à une forme modulaires avec la propriété que cette dernière interpole les valeurs de la fonction L complexe de f. Par la suite, nous dérivons l'équation fonctionnelle pour la fonction L p-adique obtenue parla distribution µf .

O gênero Phaseolus apresenta grande importância econômica no mundo, principalmente por ser uma das principais fonte de proteínas para alimentação humana. Estudos cariotípicos no gênero têm acompanhado os avanços das técnicas citogenéticas em plantas, desde análises convencionais até estudos comparativos de mapas citogenéticos construídos através da hibridização in situ fluorescente (FISH). Cromossomos artificiais de bactérias (BACs) foram utilizados como sondas em FISH na comparação entre os mapas de P. vulgaris (2n = 22), principal representante de gênero, e P. lunatus (2n = 22), uma espécie filogeneticamente próxima, revelando uma total conservação de sintenia e apenas três quebras de colinearidade. Visando estender os conhecimentos acerca da evolução do gênero, o presente estudo utilizou esses mesmos marcadores em FISH para evidenciar os principais eventos cromossômicos ocorridos entre P. vulgaris e P. microcarpus (2n = 22), uma espécie selvagem e distante filogeneticamente. Análises de bandeamento CMA/DAPI e localização de sítios de DNAr 5S e 45S e da sequência telomérica também foram realizadas. O estudo revelou que, apesar da distância filogenética entre as duas espécies, houve uma forte conservação de sintenia entre os homeólogos e apenas quatro quebras de colinearidade. Apenas eventos de inversão cromossômica foram propostos, justificando sua estabilidade numérica. Além disso, foram evidenciados padrões distintos de hibridização entre sequências repetitivas para uma mesma região cromossômica. Os resultados demonstraram que em Phaseolus a evolução cromossômica parece estar relacionada a eventos de rearranjo raros e de pouca complexidade, confirmando sua aparente estabilidade cariotípica postulada em estudos convencionais

Full textAbstract:
Nowadays licensing practices have increased in importance and relevance driving the
widespread diffusion of markets for technologies. Firms are shifting from a tactical to a strategic
attitude towards licensing, addressing both business and corporate level objectives. The Open
Innovation Paradigm has been embraced. Firms rely more and more on collaboration and
external sourcing of knowledge. This new model of innovation requires firms to leverage on
external technologies to unlock the potential of firms’ internal innovative efforts. In this context,
firms’ competitive advantage depends both on their ability to recognize available opportunities
inside and outside their boundaries and on their readiness to exploit them in order to fuel their
innovation process dynamically. Licensing is one of the ways available to firm to ripe the
advantages associated to an open attitude in technology strategy. From the licensee’s point view
this implies challenging the so-called not-invented-here syndrome, affecting the more traditional firms
that emphasize the myth of internal research and development supremacy. This also entails
understanding the so-called cognitive constraints affecting the perfect functioning of markets for
technologies that are associated to the costs for the assimilation, integration and exploitation of
external knowledge by recipient firms.
My thesis aimed at shedding light on new interesting issues associated to in-licensing
activities that have been neglected by the literature on licensing and markets for technologies. The
reason for this gap is associated to the “perspective bias” affecting the works within this stream
of research. With very few notable exceptions, they have been generally concerned with the
investigation of the so-called licensing dilemma of the licensor – whether to license out or to
internally exploit the in-house developed technologies, while neglecting the licensee’s perspective.
In my opinion, this has left rooms for improving the understanding of the determinants and
conditions affecting licensing-in practices. From the licensee’s viewpoint, the licensing strategy
deals with the search, integration, assimilation, exploitation of external technologies. As such it
lies at the very hearth of firm’s technology strategy. Improving our understanding of this strategy
is thus required to assess the full implications of in-licensing decisions as they shape firms’
innovation patterns and technological capabilities evolution. It also allow for understanding the
so-called cognitive constraints associated to the not-invented-here syndrome. In recognition of that, the
aim of my work is to contribute to the theoretical and empirical literature explaining the determinants of the licensee’s behavior, by providing a comprehensive theoretical framework as
well as ad-hoc conceptual tools to understand and overcome frictions and to ease the
achievement of satisfactory technology transfer agreements in the marketplace.
Aiming at this, I investigate licensing-in in three different fashions developed in three
research papers. In the first work, I investigate the links between licensing and the patterns of
firms’ technological search diversification according to the framework of references of the Search
literature, Resource-based Theory and the theory of general purpose technologies. In the second
paper - that continues where the first one left off – I analyze the new concept of learning-bylicensing,
in terms of development of new knowledge inside the licensee firms (e.g. new patents)
some years after the acquisition of the license, according to the Dynamic Capabilities perspective.
Finally, in the third study, Ideal with the determinants of the remuneration structure of patent
licenses (form and amount), and in particular on the role of the upfront fee from the licensee’s
perspective. Aiming at this, I combine the insights of two theoretical approaches: agency and real
options theory.

Full textAbstract:
Let K|Q be a number field and let Z(K,s) be its associated complex L-function. The analytic class number formula relates special values of Z(K,s) with algebraic invariants of the field K itself. It admits a Galois equivariant refinement known as Stark conjectures.
We have a very similar picture in the case of elliptic curves. Let E/Q be an elliptic curve and let L(E/Q,s) be its associated complex L-function. The conjecture of Birch and Swinnerton-Dyer relates the behaviour of L(E/Q,s) at s=1 to the structure of rational solutions of the equation defined by E. The equivariant Birch and Swinnerton-Dyer conjecture is obtained including in the picture the action of Galois groups.
The elliptic Stark conjecture formulated by H. Darmon, A. Lauder and V. Rotger purposes a p-adic analogue of the equivariant Birch and Swinnerton-Dyer conjecture, under several assumption. In their paper, the authors formulate the conjecture and prove it in some cases of good reduction of E at p using Garrett-Hida method and performing a factorization of p-adic L-functions. In this dissertation we focus on the elliptic Stark conjecture and we show how it is possible to extend the result of Darmon, Lauder and Rotger.
In the case of good reduction of E at p we can slightly extend the result using Hida-Rankin method. This method also gives us a better control of the constants appearing in the result, thus yielding an explicit formula which contains invariants associated with the elliptic curve. To achieve the proof we mimic the main result of Darmon, Lauder and Rotger in our setting and we make use of a p-adic Gross-Zagier formula which relates special values of the Bertolini-Darmon-Prasanna p-adic L-function to Heegner points.
In a second moment we extend both our result and Darmon-Lauder-Rotger result to the case of multiplicative reduction of E at p. In this setting we cannot use Bertolini-Darmon-Prasanna p-adic L-function due to some technical reasons. To avoid the problem we consider Castella's two variables p-adic L-function. We use both Garrett-Hida method and Hida-Rankin method. In the two cases we obtain formulae which are similar to those of the good reduction setting.Sigui K/Q un cos de nombres i sigui L(K,s) la funció L de Dedekind associada. La fórmula analítica del nombre de classes relaciona els valors especials de L(K,s) amb invariants algebraics del cos K. Aquesta formula admet un refinament Galois equivariant conegut com les conjectures de Stark. En el cas de les corbes el·líptiques ens trobem amb un escenari similar. Sigui E/Q una corba el·líptica i sigui L(E/Q,s) la seva L-sèrie complexa. La conjectura de Birch i Swinnerton-Dyer relaciona el comportament de L(E/Q,s) en el punt central crític s=1 amb l'estructura del conjunt de punts racionals de l'equació definida per E. La versió Galois-equivariant proporciona un refinament d'aquesta conjectura per al canvi de base d'E a un cos de nombres K qualsevol. La conjectura el·líptica de Stark formulada per H. Darmon, A. Lauder i V. Rotger proposa un anàleg p-àdic de la conjectura Galois-equivariant de Birch i Swinnerton-Dyer, sota vàries hipòtesis. En el seu article, els autors formulen la conjectura i la demostren en alguns casos on el primer p és un primer de bona reducció per E, usant el mètode de Garrett-Hida i demostrant pel camí una factorització de funcions L p-àdiques. En aquesta tesi doctoral estudiem i demostrem nous resultats sobre la conjectura el¿líptica de Darmon-Lauder-Rotger En el cas on p és un primer de bona reducció per E, refinem el resultat principal de Darmon-Lauder-Rotger mitjançant el mètode de Rankin-Hida, que ens dóna un millor control de les constants que apareixen en les demostracions i ens permet demostrar una fórmula explícita que involucra invariants globals associats a la corba el¿líptica. Per aconseguir-ho generalitzem la estratègia de Darmon, Lauder and Rotger, tot utilitzant la p-adic Gross-Zagier formula que relaciona els valors especials de la funció L p-àdica de Bertolini-Darmon-Prasanna amb punts de Heegner. L'altre resultat principal d'aquesta tesi és la demostració de la conjectura el·líptica de Stark en un cas on E té reducció multiplicativa en el primer p. Per a fer-ho explotem la funció L p-àdica de F. Castellà, que és una generalització a dos variables de la funció L p-àdica de Bertolini-Darmon-Prasanna.

Cette thèse est consacrée à l’étude du système de Boussinesq stationnaire:-νΔu+(u⋅∇)u+∇π=θg, div u=0,dans Ω(1a)-κΔθ+u⋅∇θ=h,dans Ω (1b)où Ω⊂R^3 est un ouvert, borné et connexe; les inconnues du système sont u,π et θ: la vitesse, la pression et la température du fluide, respectivement; ν>0 est la viscosité cinématique du fluide, κ>0 est la diffusivité thermique du fluide, g est l’accélération de la pesanteur et h est une source de chaleur appliquée au fluide.L’objectif de cette thèse est l’étude de la théorie L^p pour le système de Boussinesq en considérant deux différents types de conditions aux limites du champ de vitesse. En effet, dans une première partie, nous considérons une condition de Dirichlet non homogèneu=u_b, sur Γ (2)où Γ désigne la frontière du domaine. Dans une deuxième partie, nous considérons une condition de Navier non homogèneu⋅n=0,2[D(u)n]_τ+αu_τ=a,sur Γ(3)où D(u)=1/2 (∇u+(∇u)^T ) est le tenseur de déformation associé au champ de vitesse u, n est le vecteur normal unitaire extérieur, τ est le correspondant vecteur tangent unitaire, α et a sont une fonction scalaire de friction et un champ de vecteur tangentiel donnés sur la frontière, respectivement. De plus, la condition aux limites pour la température sera, dans les deux premières parties, une condition aux limites de Dirichlet non homogèneθ=θ_b, sur Γ. (4)Alors, premièrement, nous étudions l’existence et l’unicité d’une solution faible pour le problème (1), (2) et (4) dans le cas hilbertien. Également, l’existence de solutions généralisées pour p≥3/2 et des solutions fortes pour 12 et des solutions fortes pour p≥6/5 pour le problème (1), (3) et (4). Notez que l’hypothèse d’une frontière non-connexe, mentionnée précédemment, ne figurait pas dans cette partie du travail en raison de la restriction d’imperméabilité de la frontière.Enfin, dans la dernière partie de cette thèse, nous étudions la théorie L^p pour les équations de Stokes avec la condition de Navier (3). Plus précisément, nous examinons la régularité W^(1,p) pour p≥2 et la régularité W^(2,p) pour p≥6/5.Mots clés: système de Boussinesq; régularité L^p; solutions faibles; solutions fortes; solutions très faiblesThis thesis is dedicated to the study of the stationary Boussinesq system:-νΔu+(u⋅∇)u+∇π=θg, div u=0,in Ω(1a)-κΔθ+u⋅∇θ=h,in Ω (1b)where Ω⊂R^3 is an open bounded connected set; u,π and θ are the velocity field, pressure and temperature of the fluid, respectively, and stand for the unknowns of the system; ν>0 is the kinematic viscosity of the fluid, κ>0 is the thermal diffusivity of the fluid, g is the gravitational acceleration and h is a heat source applied to the fluid.The aim of this thesis is the study of the L^p-theory for the stationary Boussinesq system in the context of two different types of boundary conditions for the velocity field. Indeed, in the first part of the thesis, we will consider a non-homogeneous Dirichlet boundary conditionu=u_b, on Γ (2)where Γ denotes the boundary of the domain; meanwhile in the second part, the velocity field will be prescribed through a non-homogeneous Navier boundary conditionu⋅n=0,2[D(u)n]_τ+αu_τ=a,on Γ(3)where D(u)=1/2 (∇u+(∇u)^T ) is the strain tensor associated with the velocity field u, n is the unit outward normal vector, τ is the corresponding unit tangent vector, α and a are a friction scalar function and a tangential vector field defined both on the boundary, respectively. Further, the boundary condition for the temperature will be, in the first two parts of the thesis, a non-homogeneous Dirichlet boundary conditionθ=θ_b, on Γ. (4)Then, firstly, we study the existence and uniqueness of the weak solution for the problem (1), (2) and (4) in the hilbertian case. Also, the existence of generalized solutions for p≥3/2 and strong solutions for 12 and strong solutions for p≥6/5 for the problem (1), (3) and (4). Note that the assumption of a non-connected boundary, which was mentioned before, will not appear here due to the impermeability restriction on the boundary.Finally, in the last part of this thesis, we study the L^p-theory for the Stokes equations with Navier boundary condition (3). Specifically, we deal with the W^(1,p)-regularity for p≥2 and the W^(2,p)-regularity for p≥6/5.Keywords: Boussinesq system; L^p-regularity; weak solutions; strong solutions; very weak solutions

Full textAbstract:
Profit and Loss (P&L) explain analysis is an income statement produced by Product Control Team for traders to control the daily fluctuation in the value of a portfolio of trades to the root causes of the changes. This daily income provides users with a coherent breakdown of the drivers of P&L movements between two points in time with reference to a selected number of easily understandable pricing factors. P&L Attribution (also called P&L explain) can be calculated in two ways, either the risk based method or step re-evaluation method. This paper aims at understanding both methodologies from a theoretical point of view and shows the differences of both calculations methods and how they are interdependent in the daily work of a trader in the sense that both methods give a rational to the P&L from different perspectives. The risk based method involves the calculation of the trades sensitivities (also known as the Greeks) and then using them to predict the expected change in the P&L from one period to the next by using the actual market changes in the factors driving the transaction price over the same period and the transaction’s sensitivity to those factors. Whereas the re-evaluation method is calculated by aggregating the impact of different valuation scenarios and not on fixed sensitivitiesAnalys och rapportering av balansräkning ger användarna en sammanhängande uppdelning av drivkrafterna för P&L rörelser mellan två punkter i tid med hänvisning till ett urval av lättförståeliga prisfaktorer. P&L attribution kan beräknas på två sätt, känslighet och scenariobaserad metoder. Detta arbete syftar till att förstå båda metoderna ur ett teoretiskt perspektiv och visar skillnaderna och hur de beror på varandra. Känslighetsmetoden innebär beräkning av en handels känslighet (även känd som beräkning av grekerna) och sedan använda dem för att förutsäga den förväntade förändringen i P&L från en period till nästa genom att använda de faktiska marknadsförändringarna i de faktorer som driver transaktionspriset under samma period och transaktionens känslighet för dessa faktorer. Omvärderingsmetoden beräknas genom att olika värderingsscenariers inverkan sammanställs och inte på fasta känsligheter.

sector affects positively plants productivity and export decision. Secondly liquidity constraints are important for the calculation of firm's productivity because
they are a second source of firm's heterogeneity. Third liquidity constraints are important for firm's internationalization

Full textAbstract:
Motivated by the need to understand which are the underlying forces that trigger network evolution, we develop a multilevel theoretical and empirically testable model to examine the relationship between changes in the external environment and network change. We refer to network change as the dissolution or replacement of an interorganizational tie, adding also the case of the formation of new ties with new or preexisting partners. Previous research has paid scant attention to the organizational consequences of quantum change enveloping entire industries in favor of an emphasis on continuous change. To highlight radical change we introduce the concept of environmental jolt. The September 11 terrorist attacks provide us with a natural experiment to test our hypotheses on the antecedents and the consequences of network change. Since network change can be explained at multiple levels, we incorporate firm-level variables as moderators. The empirical setting is the global airline industry, which can be regarded as a constantly changing network of alliances. The study reveals that firms react to environmental jolts by forming homophilous ties and transitive triads as opposed to the non jolt periods. Moreover, we find that, all else being equal, firms that adopt a brokerage posture will have positive returns. However, we find that in the face of an environmental jolt brokerage relates negatively to firm performance. Furthermore, we find that the negative relationship between brokerage and performance during an environmental jolt is more significant for larger firms. Our findings suggest that jolts are an important predictor of network change, that they significantly affect operational returns and should be thus incorporated in studies of network dynamics.

Full textAbstract:
In this thesis the impact of R&D expenditures on firm market value and stock returns is examined. This is performed in a sample of European listed firms for the period 2000-2009. I apply different linear and GMM econometric estimations for testing the impact of R&D on market prices and construct country portfolios based on firms’ R&D expenditure to market capitalization ratio for studying the effect of R&D on stock returns. The results confirm that more innovative firms have a better market valuation,investors consider R&D as an asset that produces long-term benefits for corporations. The impact of R&D on firm value differs across countries. It is significantly modulated by the financial and legal environment where firms operate. Other firm and industry characteristics seem to play a determinant role when investors value R&D. First, only larger firms with lower financial leverage that operate in highly innovative sectors decide to disclose their R&D investment. Second, the markets assign a premium to small firms, which operate in hi-tech sectors compared to larger enterprises for low-tech industries.
On the other hand, I provide empirical evidence indicating that generally highly R&D-intensive firms may enhance mispricing problems related to firm valuation. As R&D
contributes to the estimation of future stock returns, portfolios that comprise high R&D-intensive stocks may earn significant excess returns compared to the less innovative after controlling for size and book-to-market risk. Further, the most innovative firms are generally more risky in terms of stock volatility but not systematically more risky than low-tech firms. Firms that operate in Continental Europe suffer more mispricing compared
to Anglo-Saxon peers but the former are less volatile, other things being equal. The sectors where firms operate are determinant even for the impact of R&D on stock returns; this effect is much stronger in hi-tech industries.

Paper 1 : A geometrical version of Hardy's inequality for W_0^{1,p}(D).
The aim of this article is to prove a Hardy-type inequality, concerning functions in W_0^{1,p}(D) for some domain D in R^n, involving the volume of D and the distance to the boundary of D. The inequality is a generalization of a previously proved inequality by M. and T. Hoffmann-Ostenhof and A. Laptev, which dealt with the special case p=2.
Paper 2 : A Hardy inequality in the Half-space.
Here we prove a Hardy-type inequality in the half-space which generalize an inequality originally proved by V. Maz'ya to the so-called L^p case. This inequality had previously been conjectured by the mentioned author. We will also improve the constant appearing in front of the reminder term in the original inequality (which is the first improved Hardy inequality appearing in the litterature).
Paper 3 : Hardy type inequalities for Many-Particle systems.
In this article we prove some results about the constants appearing in Hardy inequalities related to many particle systems. We show that the problem of estimating the best constants there is related to some interesting questions from Geometrical combinatorics. The asymptotical behaviour, when the number of particles approaches infinity, of a certain quantity directly related to this, is also investigated.
Paper 4 : Various results in the theory of Hardy inequalities and personal thoughts.
In this article we give some further results concerning improved Hardy inequalities in Half-spaces and other conic domains. Also, some examples of applications of improved Hardy inequalities in the theory of viscous incompressible flow will be given.

Dans cette thèse, nous construisons des fonctions L p-adique algébriques pour les familles de représentations galoisiennes attachées aux familles p-adique analytiques de représentations automorphes en utilisant le formalisme des complexes de Selmer.

This is achieved mainly through making a modification of the Selmer complex to ensure that we deal with perfect complexes and proving a control theorem for the local Euler factors at places not lying above p. The control theorem for local Euler factors is obtained by studying the variation of monodromy under pure specializations of p-adic families of Galois representations restricted to decomposition groups at places of residue characteristic different from p. This allows us to prove a control theorem for the algebraic p-adic L-functions that we construct for Hida families of ordinary cusp forms and ordinary automorphic representations for definite unitary groups. For the Hida family of ordinary cusp forms, we construct a two-variable algebraic p-adic L-function and formulate a conjecture relating it with the analytic p-adic L-function constructed by Emerton, Pollack and Weston. Using results due to Kato, Skinner and Urban, we prove this conjecture in some special cases

A consequence of the Hahn-Banach theorem is the classical bipolar theorem which states that the bipolar of a subset of a locally convex vector pace equals its closed convex hull. The space $\L$ of real-valued random variables on a probability space $\OF$ equipped with the topology of convergence in measure fails to be locally convex so that - a priori - the classical bipolar theorem does not apply. In this note we show an analogue of the bipolar theorem for subsets of the positive orthant $\LO$, if we place $\LO$ in duality with itself, the scalar product now taking values in $[0, \infty]$. In this setting the order structure of $\L$ plays an important role and we obtain that the bipolar of a subset of $\LO$ equals its closed, convex and solid hull. In the course of the proof we show a decomposition lemma for convex subsets of $\LO$ into a "bounded" and "hereditarily unbounded" part, which seems interesting in its own right.

O objetivo final na área médica reconstrutiva é a restauração estrutural e funcional do tecido ao estado natural. Em cirurgias de fixação de fratura, uma fixação estável e confiável é uma condição absoluta para o sucesso. Implantes metálicos geralmente oferecem boa fixação. Entretanto, várias complicações e efeitos adversos têm sido descritos a respeito de seus usos. A ideia de desenvolver implantes que gradualmente perdem resistência e são reabsorvidos após cicatrização óssea tem estimulado diversas investigações na área dos biomateriais. Implantes biorreabsorvíveis podem ser produzidos a partir de polímeros cujas unidades monoméricas estão naturalmente presentes no organismo, permitindo sua degradação e reabsorção sem acúmulo de reações tóxicas. O processo de moldagem por compressão, tradicionalmente utilizado para a fabricação de dispositivos biorreabsorvíveis autorreforçados, tais como placas e parafusos, apresenta desvantagens em relação à qualidade final do produto e baixa flexibilidade de fabricação. O presente trabalho teve como objetivo o desenvolvimento de uma nova tecnologia para a fabricação de implantes biorreabsorvíveis. No contexto desta pesquisa, implantes tipo parafuso foram fabricados para aplicações em cirurgias de reparo do tecido ósseo. Inicialmente, barras circulares foram produzidas através de processo de injeção. Para o aumento dos níveis de resistência mecânica, as barras foram submetidas a um processo de autorreforço. Na sequência, utilizou-se a usinagem na obtenção da forma, da qualidade dimensional e da superfície adequada para a interação com o tecido ósseo. Os resultados desse conjunto de etapas e processos revelaram um produto com propriedades mecânicas, tolerâncias geométricas e características de superfície adequadas para uma fixação segura e com qualidade superior a apresentada por implantes moldados disponíveis no mercado.
