Structural analysis of the 17th century warship Vasa : Influence of the dowels on the stiffness of the hull

Muñoz García, Marina, Hurtado Sierra, Juan Carlos January 2014 (has links)
After 333 years under depths of the Baltic Sea, the warship Vasa was salvaged and nowadayslies in a dry dock inside the Vasa Museum in Stockholm. Its current support system, which consists on eighteen cradle-stanchions pairs of steel, is not able to handle the present loads in a satisfactory manner. Experimental tests showed that the Vasa's hull is gradually deforming mainly due to creep behavior. Thus, in order to preserve the Vasa for future generations, a new support system has to be implemented in a foreseeable future. There are several factors to take into consideration for its construction, which are: the degradation of the oak, its current mechanical properties and its inhomogeneity in addition to the climatic conditions of the Museum and the impossibility of taking unlimited specimens for its analysis. Hence, it is crucial to investigate the areas where the stresses and deformations are critical in the ship and how affected is the stiffness of the hull, its most important component. In this dissertation work two Finite Element Analyses are accomplished. The first study consists on the creation of a superelement of a section of Vasa's hull with the intention of investigating the influence of the dowels on the stiffness of the hull. In the second analysis a simplied model of the entire warship Vasa is created in order to analyze it and locate possible critical areas on the hull due to its own weight and the stresses originated by the support system. The software selected for these simulations are Abaqus and CreoSimulate 2.0. From the first study it is concluded that that the dowels do not have a signicant influence in the stiffness coeffcients of the hull. The second analysis determines that the maximum stresses are located on the bottom part of the hull. This dissertation work concludes with a suggested future work.

La Commission de la capitale nationale et l’Île de Hull : entre identité nationale et conscience régionale (1959-1979)

Legris-Dumontier, Sophie-Hélène 28 January 2014 (has links)
Au moment de sa création, en 1959, la Commission de la capitale nationale (CCN) a pour but d’intégrer les villes de Hull et d’Ottawa, cette union devant symboliser, plus largement, celle des deux peuples fondateurs du Canada. Or, ce projet a provoqué d’importants débats politiques à Hull au fil des années. En se voyant ainsi intégrée à la région de la capitale nationale (RCN), Hull perdait une partie de son autonomie. Cette thèse propose une étude de la CCN pendant la rénovation urbaine de l’Île de Hull des années 1960 et 1970 afin d’y cerner le rôle joué par le débat sur la question nationale. Il s’agit d’un élément moteur de l’action de la CCN. En fait, la question nationale se trouve à plusieurs niveaux de la problématique. Ce sujet peu exploré donne à cette recherche son originalité. En examinant les relations entre les acteurs de la revitalisation du centre-ville, soit la CCN, le conseil municipal de Hull, les regroupements citoyens et le gouvernement du Québec, la thèse opte pour une perspective à la fois politique, institutionnelle et sociale. Un jeu de pouvoir entre les paliers gouvernementaux prend place alors que Hull et Ottawa se disputent les investissements fédéraux. Les citoyens de l’Île de Hull s’engagent dans les assemblées citoyennes et y développent une conscience régionale qui tardait à s’affirmer.

Swaption Pricing under Hull-White Model using Finite Difference Method with Extension to European Cancellable Swap : Swaption Pricing under Hull-White Model using Finite Difference Method with Extension to European Cancellable Swap

Lin, Xinyan January 2015 (has links)
This thesis mainly focuses on analyzing and pricing European swaption via Crank{Nicolson Finite Dierence method. This paper begins with some rather common instruments, denitions and valuations are also provided. MATLAB is the main computer language used throughout this paper, for the numerical examples, the MATLAB codes are also provide in the appendix in order for reader to reproduce the result. Also, the paper extends to price cancellable swap in the end.

Classifcation of Conics in the Tropical Projective Plane

Ellis, Amanda 18 November 2005 (has links)
This paper defines tropical projective space, TP^n, and the tropical general linear group TPGL(n). After discussing some simple examples of tropical polynomials and their hypersurfaces, a strategy is given for finding all conics in the tropical projective plane. The classification of conics and an analysis of the coefficient space corresponding to such conics is given.

The lichen flora of Hull, with particular reference to zonal distribution and environmental monitoring

Seaward, Mark R.D. January 2004 (has links)
Yes / The role of lichens as environmental monitors is widely recognised. Not only are they valuable as indicators of habitat stability and enyironmental continuity, but they are also effectiye in monitoring environmental quality. more particularly air and soil (and more recently water) pollution. In the past. the main role of lichens in this context has been to monitor sulphur dioxide air pollution. especially stable and rising levels (Seaward 1993). Howeyer, it has also been shown that lichens arc effective monitors of falling levels of gaseous sulphur dioxide and indeed of other pollutants. some of which are manifesting themselves as a consequence of the reduction in the former; of particular interest in this respect is the use of lichens to detect and determine the extent of qualitative changes in air pollution such as the impact of acid rain and hypertrophication (Seaward 1997: Seaward & Coppins 2(04).
