13. Estudo de viabilidade do sistema de ancoragem de uma unidade flutuante de produção e armazenamento \"FPSO\" acoplada a um sistema de completação seca \"TLWP\". / Mooring system feasibility study of a floating production and storage unit \"FPSO\" coupled to a dry tree system \"TLWP\".
The oil and gas production in Brazilian fields are commonly found in deep water and situated far away from the coast, reaching distances of more than 100 km as, for example, in the Campos Basin or Santos Basin. Due to the heavy oil and lack of pipeline infrastructure found in these fields, not only subsea equipments that must support high pressure but also l

14. Procedural textures mapping using geodesic distances / Mapeamento de texturas procedurais usando distâncias geodésicas
O mapeamento de texturas é uma técnica bastante importante para adicionar detalhamento a modelos geométricos. O mapeamento de texturas baseadas em imagens costuma ser a abordagem preferida, mas faz uso de imagens pré-computadas que são mais adequadas à representação de padrões estáticos. Por outro lado, texturas procedurais oferecem uma alternativa

15. Gene flow of genetically modified soybeans, in summer and winter sowings, with isolations of soybean or maize / Fluxo gênico de soja geneticamente modificada, em semeaduras de verão e de inverno, com isolamentos de soja ou milho
Genetically modified soybean, tolerant to glyphosate, expanded its growing area in few years becoming the most sown in the country. The advantages of its use are many compared to the conventional soybean, which has led soybean farmers to prefer it. However, since some markets still prefer conventional soybean and its production occurs in smaller areas, there

16. Sistema e processo para geração, sincronização remota e comparação de sinais temporais precisos / System and process for the generation, remote synchronization and comparison of precise time signals
This thesis present new proposals for time dissemination systems, which were analyzed and implemented as complete solutions providing high resolution in radio links focusing in the requirements of the new geolocation system known as GEOLOCAL. The solutions found are useful for other applications equiring time synchronization. The work has been developed in d

17. InteraÃÃes contingentes em ambientes virtuais de aprendizagem. / Contingent Interaction in Learning Management Systems
The purpose of this research is to develop an analytical system to understand the interactions in a LMS that promote learning (contingent interactions). The LMS are a class of software for the design, suport and management of Internet-based courses. Integrate Information and Communication Technologies in order to create an environment that enables the proces

18. AnÃlise de performance de sÃlitons Ãpticos espaÃo-temporais em guia planar com nÃo-linearidade cÃbico quintica periodicamente modulada e circuitos lÃgicos operando nos regimes Kerr instantÃneo e relaxado. / Performance analysis of the spatio-temporal optical solitons in a planar guide with cubic quintic nonlinearity periodically modulated and logic circuits operating in regimes Kerr instantaneous and relaxed.
In this work, the propagation and stability of spatiotemporal optical solitons (or optical bullets) in a planar waveguide with periodically modulated cubic-quintic nonlinearity is presented numerically as a function of the amplitudes of modulation , the frequency of modulation and the propagation distance .With the objective of ensure the stability and preve

19. A new species of Tormopsolus (Digenea: Acanthocolpidae) parasite of Genypterus brasiliensis (Teleostei: Ophidiidae) from the Brazilian coast
Tormopsolus brasiliensis sp. nov. is described from the intestine of Genypterus brasiliensis Regan, 1903, from Brazil. The new species is characterized mainly by having an almost square terminal oral sucker, a pharynx of the same size or larger than the oral sucker, and testes very close to each other and without vitelline follicles between them. Tormopsolus

20. Distance Learning, curriculum and competences: a suggestion for graduation on Business Management on-line. / Educação a distância, currículo e competência: uma proposta de formação on-line para a gestão empresarial
Society, in general, has been quickly changing in all senses. The development of Information and Communication Technologies (TICs) has significantly contributed to accelerate the process of change. Nowadays, individuals virtually share the same interests and goals within the knowledge realm. Information and knowledge nets are built every time. Information gl

21. O sistema estrutural na obra de Oscar Niemeyer
Oscar Niemeyer states that architecture and structure should develop together. However, what is normally seen is a distance between these two elements of construction. This work shows a group of important constructions where the structural system had a important role in the final architectural design, as in the work of architects such as Affonso Reidy, Paulo

22. An analytical treatment of the energy spectrum of hydrogen-like atoms perturbed by a generalized van der Waals potential
Hydrogen-like atoms are two-particle systems governed with spherically symmetric potentials, their non-relativistic Schrödinger equations can be solved analytically yielding exact information about their spectra. Vigorous interest in the investigation of their behavior under the influence of external fields has been increased over the years. The main goal o

23. Electromagnetic fields and acute lymphocytic leukemia in children living in the Metropolitan Area of Sao Paulo / Campos eletromagnéticos e leucemia linfocítica aguda em crianças residentes na região metropolitana de São Paulo
Introduction-The Acute Lymphocytic Leukemia (ALL) is the most common cancers in children. Some epidemiological studies have identified increased risk of ALL in children exposed to magnetic fields generated by high voltage power lines, however, this association was not confirmed by other studies. Purpose- Check the association between exposure to magnetic fie

24. ConstruÃÃo de cÃdigos de bloco lineares via transformadas digitais
New families of error-correcting codes, created from the Fourier number theoretic transform (Fourier Codes) and from trigonometric transforms over finite fields (FFCT-4e and FFST-4e Codes), are introduced in this dissertation. The code parity-check matrix, its dimension and minimum distance are obtained from the eigenstructure of the unitary Fourier number t
