A bibliographic and documentary research was carried out on Quality Management, Quality in Brazilian Public Management, Excellence in Management and its fundamentals and criteria, and Quality Management in the Brazilian Navy. For the study, a qualitative methodology was used, through a multiple case study, which analyzed 30 organizations of the Brazilian Navy. As evidence that emerged from the study, it was pointed out that the nature of military organizations - operational, health, support and teaching - can be a determining factor in the adoption of practices aimed at improving governance. The main limitation of the research is the non-incorporation of the view of the actors involved in the studied reality through interviews, given the limited time to perform the research. Obtaining the perspective of managers and employees on the governance practices adopted would add information for a more complete analysis. Understanding the efforts to improve governance in the different military organizations of the Brazilian Navy can generate important clues for the continuous development of a quality program in the institution. With the need for public institutions to seek ways to become more efficient in the application of their resources, the study can contribute to the achievement of managerial objectives in order to meet the growing demands of Brazilian society. The present study contributes to broaden the scope of the evaluation of the efforts to improve governance in the military organizations of the Brazilian Navy. / Este estudo pretende analisar de que forma ocorre a adoção de práticas e ferramentas na busca pela melhoria da governança na Marinha do Brasil, no contexto dos diferentes tipos de organizações militares que as implementam. Foi realizada pesquisa bibliográfica e documental sobre a Gestão da Qualidade, a Qualidade na Gestão Pública brasileira, a Excelência da Gestão e seus fundamentos e critérios, e a Gestão da Qualidade na Marinha do Brasil. Para o estudo, foi utilizada metodologia qualitativa, por meio de um estudo de caso múltiplo, que analisou 30 organizações da Marinha do Brasil. As evidências que emergiram do trabalho apontaram que a natureza das organizações militares – operacionais, de saúde, de apoio e de ensino – pode ser um fator determinante na adoção de práticas voltadas para o aprimoramento da governança. A principal limitação da pesquisa é a não incorporação da visão dos atores envolvidos na realidade estudada por meio de entrevistas, em face do tempo restrito para realizar o estudo. A obtenção da perspectiva dos gestores e dos colaboradores sobre as práticas de governança adotadas acrescentaria informações para uma análise mais completa. A compreensão dos esforços para o aprimoramento da governança nas diferentes organizações militares da Marinha do Brasil pode gerar pistas importantes para o contínuo desenvolvimento de um programa de qualidade na instituição. Com a necessidade de as instituições públicas buscarem formas para se tornarem mais eficientes na aplicação dos recursos que administram, o estudo pode contribuir para o alcance dos objetivos gerenciais a fim de atender às crescentes demandas da sociedade brasileira. O presente estudo contribui para ampliar o escopo da avaliação dos esforços para a melhoria da governança nas organizações militares da Marinha do Brasil.

Initially, we examine relevant concepts on Knowledge Management and pinpoint their importance to Public Administration, particularly to hierarchical organizations such as the Armed Forces. Later on, we provide a brief contextualization of the theories of KM based on the organizational structure of the Brazilian Navy Quartermasters Corps and the current principles of the Neptune Program. We also highlight the continuous pursuit for excellence in Public Administration as a source of inspiration to fostering the consolidation of KM within organizations. The utilization of qualitative research methods allows for an accurate understanding of the tenets of KM and brings to the forefront the major facilitators and barriers to knowledge sharing in professional environments. This approach enables the identification of the main practical tools observed in the fieldwork and does not deprive oneself from bringing up different tools haply suggested by the respondents. Subsequently, this study makes evident that the Neptune Program, whose website may be regarded as a virtual environment of knowledge sharing, has the necessary requirements to take over the role of a provider of a shared space for knowledge creation - 'Ba'. In this sense, one may infer that the Neptune Program provides solid opportunities to consolidate KM within Brazilian Navy Quartermaster Corps. Finally, this work concludes that the Admiral Newton Braga Instruction Center (CIANB) has an outstanding potential to become the 'Corporate University for the Quartermaster Corps' in the near future. / Utilizando-se da perspectiva das teorias sobre Gestão do Conhecimento (GC), este trabalho tem como objetivo principal identificar os problemas e desafios que se apresentam às Organizações Militares responsáveis pela formação, especialização, aperfeiçoamento e capacitação dos Oficiais do Corpo de Intendentes da Marinha (CIM). Para tanto, são apresentados alguns conceitos relevantes sobre a Gestão do Conhecimento, bem como a sua importância na Administração Pública, em particular nos ambientes hierarquizados, como é o caso das Forças Armadas. Posteriormente, é feita uma breve contextualização sobre o caso, no que tange à estrutura organizacional analisada e os princípios do Programa Netuno, bem como sobre a busca pela excelência na gestão pública como fonte inspiradora. Utilizando-se da metodologia qualitativa de pesquisa, o trabalho busca compreender os principais aspectos relacionados à gestão do conhecimento, ressaltando as principais barreiras e facilitadores ao compartilhamento do conhecimento neste segmento, bem como elencando as principais ferramentas práticas observadas, e não se privando de trazer à tona algumas ferramentas sugeridas pelos entrevistados. Na sequência, traz a percepção de que o próprio Programa Netuno, fazendo uso de seu sítio eletrônico, possui atributos para assumir o papel de um contexto capacitante – 'Ba' – especialmente no ambiente virtual de compartilhamento do conhecimento, o qual oferece muitas oportunidades para consolidação da GC no Corpo de Intendentes da Marinha. E por fim, não menos importante, o trabalho conclui que o Centro de Instrução Almirante Newton Braga (CIANB) tem enorme potencial para se tornar a 'Universidade Corporativa do Corpo de Intendentes da Marinha'.

A study was made in order to deduce whether certain chemical species, namely water (H2O) and carbon monoxide (CO), are present in the atmosphere of the exoplanet WASP-107 b, which lies about 200 light-years away from Earth in the constellation Virgo. The project was carried out at Uppsala University at the Department of Physics and Astronomy. This was done through the use of transmission spectroscopy and executed using a cross-correlation technique, one of the leading methods available today to extract exoplanetary atmospheric information. The data used was collected during a transit which occured in March 2022, originally gathered by the spectrograph CRIRES+ stationed at Very Large Telescope (VLT) in Paranal. WASP-107 b is a warm Jupiter-type planet, and since the aforementioned chemical species exhibit spectral lines mainly in the infrared (0.95-5.3 μm), it makes CRIRES+ a desirable instrument due to its specialization for working in the infrared. The data analysis was performed using several scripts built in Python with subsequent data-reduction methods. The data-reduction methods used for this purpose was the standard ESO CRIRES+ data reduction pipeline which includes removal of systemic sources of noise such as dead pixels and cosmic rays, and SysRem, which is an algorithm used to remove any trends with time and any constant features in time for each pixel time series. SysRem is currently one of the most efficient way available for doing so, and is commonly used in these types of studies. Several detection maps were then generated and studied in order to deduce whether a detection had been made or not. For this project, one exoplanet was examined and its atmosphere was probed for H2O and CO. The cross-correlation templates utilized were a combination of both species as well as one corresponding to only CO. The detection maps generated from the cross-correlation analysis initially suggested non-detections for all combinations of SysRem iterations and templates, except for two which presented features that might imply a detection but without any strong certainty. Those results indicate the possible existence of CO in the atmosphere of WASP-107 b, but further investigation is needed in order to determine their validity. / Denna rapport beskriver en studie som utförts för att undersöka ifall vissa kemiska arter, nämligen vatten (H2O) och kolmonoxid (CO), existerar i atmosfären kring exoplaneten WASP-107 b. Exoplaneten ligger cirka 200 ljusår bort från jorden i konstellationen Jungfrun. Arbetet utfördes på Uppsala universitet på institutionen för fysik och astronomi, eller Department of Physics and Astronomy. Detta gjordes huvudsakligen med hjälp av transmissionsspektroskopi och cross-correlation - en av de ledande metoderna idag för att analysera exoplanetära atmosfärer. Datan som använts för denna studie samlades in under en transit som skedde i mars 2022 med hjälp av spektrografen CRIRES+, stationerad vid Very Large Telescope (VLT) i Paranal. WASP-107 b klassas som en varm Jupiter, och eftersom de undersökta kemiska arterna huvudsakligen uppvisar spektrallinjer i det infraröda området (0.95-5.3 μm), är CRIRES+ ett sunt val då spektrografen är specialiserad på att undersöka infrarött ljus. Dataanalysen utfördes genom användningen av flertal script, byggda i Python med påföljande datareduktion. De datareduktionsmetoder som användes i detta syfte var ESO CRIRES+ standard data reduction pipeline, vilken inkluderar avlägsnandet av systematiska källor till brus såsom döda pixlar och den kosmiska bakgrundsstrålningen, och SysRem, vilket är en algoritm som används för att ta bort trender samt konstanta drag beroende på tid utmed varje pixelserie. I nuläget är SysRem en av de mer effektiva sätten att göra detta på, och är en vanlig metod i studier som denna. I detta projekt blev en exoplanet undersökt och dess atmosfär granskad för att se ifall H2O och CO förekommer i den. De cross-correlation templates som användes bestod av en som använde en kombination av båda kemiska arter, tillika en som endast detekterade CO. De detection maps som genererats från cross-correlation analysen föreslog först en ickedetektion för alla kombinationer av SysRem iterationer och templates, förutom två, vilka uppvisade signalement som möjligtvis indikerade en detektion, men utan särskild stark säkerhet. Dessa resultat föreslog en möjlig detektion av CO i atmosfären, men för att säkerställa detta krävs vidare undersökning.

Seafloor compliance is a non-intrusive geophysical method sensitive to the shear modulus of the sediments below the seafloor. A compliance analysis requires the computation of the frequency dependent transfer function between the vertical stress, produced at the seafloor by the ultra low frequency passive source-infra-gravity waves, and the resulting displacement, related to velocity through the frequency. The displacement of the ocean floor is dependent on the elastic structure of the sediments and the compliance function is tuned to different depths, i.e., a change in the elastic parameters at a given depth is sensed by the compliance function at a particular frequency. In a gas hydrate system, the magnitude of the stiffness is a measure of the quantity of gas hydrates present. Gas hydrates contain immense stores of greenhouse gases making them relevant to climate change science, and represent an important potential alternative source of energy. Bullseye Vent is a gas hydrate system located in an area that has been intensively studied for over 2 decades and research results suggest that this system is evolving over time. A partnership with NEPTUNE Canada allowed for the investigation of this possible evolution. This thesis describes a compliance experiment configured for NEPTUNE Canada’s seafloor observatory and its failure. It also describes the use of 203 days of simultaneously logged pressure and velocity time-series data, measured by a Scripps differential pressure gauge, and a Güralp CMG-1T broadband seismometer on NEPTUNE Canada’s seismic station, respectively, to evaluate variations in sediment stiffness near Bullseye. The evaluation resulted in a (- 4.49 x10-3± 3.52 x 10-3) % change of the transfer function of 3rd October, 2010 and represents a 2.88% decrease in the stiffness of the sediments over the period. This thesis also outlines a new algorithm for calculating the static compliance of isotropic layered sediments.
