▼ I used a compilation of publicly available, free-air and Bouguer-corrected gravity and ship-borne magnetic surveys of the Bahama carbonate platform to determine its underlying crustal type, total sedimentary thickness, plate tectonic history, and petroleum potential. Gravity and magnetic data provide important constraints on the crustal structure of the Bahamas because existing seismic reflection data are unable to penetrate the up-to-7-km-thick carbonate cover of the platform. I created gravity and magnetic models for six 700-1400 km-long, regional dip transects and one 2000-km-long strike transect crossing the Bahamas and the southeastern margin of North America. I generated magnetic models to create a depth-to-basement map that is consistent with a depth-to-basement map that I made independently using gravity data. Both magnetic and gravity maps were combined to create an overall basement depth and structure map for the Bahama platform region. These maps show basement crustal rocks with a density 2.8 g/cm3 and crustal thicknesses about twice as thick as normal oceanic crust. I interpret most of the Bahama basement to have formed as a southeasterly continuation of the volcanic passive margin of the eastern USA that formed during the Triassic (~201 Ma) eruption of the Central Atlantic Magmatic Province now found on Africa, southeastern North America, and northern South America. Locally thick crustal areas with within the Bahamas are interpreted as seamounts with the volcanic passive margin. I used variations in sedimentary thicknesses derived from the gravity and magnetic-based depth of basement map along with estimated subsidence from sparse wells and heat flow values based on measurements made in the Bahamas region to calculate the thermal maturity of an inferred Late Jurassic source rock deposited in the Bahamas area. Subsidence modeling supports greater tectonic subsidence over the thinner crust of the large igneous crust areas of the Great Bahama bank than for thicker continental crust beneath eastern Florida. Subsidence models predict peak maturation and generation for Upper Jurassic rocks at modern depths greater than 4500 m occurred in the mid Miocene less than 20 million years ago using an average heat flow of 40 mW/m2 measured in the Bahamas area. Assuming limited upward vertical migration of hydrocarbons, deeper wells (7-8 km) would be needed to penetrate to the depth of reservoirs where hydrocarbons are mature.

▼

In this dissertation we study the motion of artificial satellites around asymmetric andinhomogeneous bodies of our solar system, focusing on satellite orbits around the Moon, theasteroid Vesta and the Jupiter's moon Europa. Our purpose is to analyze the perturbations on asatellite orbit originated in the asymmetries of the gravitational field of the central body. Weexamine the role of rotation of the main body and also the third body effect (for instance theeffect of the Earth for lunar orbiters) on satellite motion. We construct gravity models ofdifferent complexity, starting with the relatively simple ones and we gradually develop highdegree and order models. Based on them, we are able to predict the time evolution of thesatellite orbits and to locate the initial conditions of orbits that keep constant or almostconstant some of their characteristics, such as their eccentricity or argument of pericenter. That kind of orbits could be of practical interest as they require minimum passive control. For theglobal analysis of the phase space and the location of the periodic orbits of the system wepropose the use of an efficient Frequency Analysis method that provides fast and accurateresults even for high complexity gravitational models.

▼ O crescimento e o desenvolvimento econômico de um país estão diretamente ligados ao comércio internacional, que proporciona a ampliação de uma gama de produtos para consumo, assim como ganhos de eficiência, economias de escala, aumento da competição e consequente redução de preços. Os fatores associados às relações econômicas deste comércio auxiliam no entendimento e na ampliação dos fluxos comerciais e, consequentemente, na criação de novos consumidores. Diversos fatores influenciam o comércio entre países, como o nível de produtividade de cada país exportador, as vantagens comparativas existentes na produção, a proporção empregada dos fatores de produção, a presença de economias de escalas, a ausência ou existência de barreiras comerciais e os fluxos passados de comércio, que, por sua vez, influenciam positivamente o comércio presente, que é um processo dinâmico. Esses fatores são relevantes na determinação do comércio internacional e importantes na definição do potencial de comércio existente entre as nações. O potencial de comércio permite observar o nível de integração dos mercados, a existência de comércio inexplorado e a possibilidade de adoção de políticas comerciais para expansão do comércio. Neste sentido, objetivou-se analisar as variáveis determinantes do comércio internacional brasileiro e identificar o potencial de comércio existente nas transações efetuadas nos três setores em análise - básicos, manufaturados e semimanufaturados - no período de 2000 a 2011. Especificamente, buscou-se: a) avaliar os efeitos dominantes dos fatores que afetam o comércio unilateral entre o Brasil e seus principais parceiros, notadamente os fluxos passados, por setor; e b) identificar, por meio do índice do potencial de comércio, para quais setores e países é possível o Brasil ampliar suas relações comerciais. O modelo teórico usado foi a teoria de comércio internacional e do modelo gravitacional. Para atingir os objetivos propostos na pesquisa, foi estimado um modelo a partir do modelo gravitacional com técnica de dados em painel dinâmico e, em seguida, calculados os índices de potencial de comércio para os setores em estudo e para os pares de países da amostra. As variáveis inclusas neste modelo de análise foram: fluxos de exportações do ano anterior, PIB do país importador, PIB do Brasil, taxa de câmbio do país importador, taxa de câmbio do Brasil, dummy para crise, tarifa ad valorem e distância. Os resultados dos coeficientes encontrados para os setores de produtos básicos, manufaturados e semimanufaturados indicam que a renda brasileira e a renda do país importador são fortes determinantes das exportações de produtos básicos, manufaturados e semimanufaturados.

▼ Fatty acid components on yeast plasma membrane were critical in maintaining proper cell activity during bioethanol fermentation. The alteration of fatty acid composition on yeast plasma membrane was recognized as an adaptive response to several environmental stress including osmotic pressure, ethanol inhibition and nutrients limit. These stresses were exacerbated under very-high-gravity condition in which excessive fermentable sugar was provided in feedstock. Controlling redox potential was proved beneficial in improving yeast performance under very-high-gravity condition. Fatty acid synthesis and desaturation pathways involved dissolved oxygen as well as balance between NAD+/NADH and NADP+/NADPH which could be influenced by the regulation of redox potential in media. In this study, fatty acid composition profiles under different glucose concentrations and different redox potential control level were examined. Its connection with yeast cell growth, ethanol productivity and other metabolites’ concentrations were studied as well to reveal any causal correlation between redox potential control, membrane fatty acid composition and yeast activity. Two glucose concentrations used in this study were 200 g/L and 300 g/L which represented normal and very high gravity respectively in bioethanol fermentation. In 300 g/L fermentation, three redox conditions were adopted while two different redox conditions were used in 200 g/L fermentation. Biomass concentration, ethanol productivity and fatty acid composition were observed to be affected by both gravity and ORP control strategy. Final biomass concentrations were 4.302 g/L in 200 g/L glucose with no ORP control condition and 7.658 in 200 g/L glucose with ORP controlled at -100 mV condition. In 300 g/L glucose fermentation, final biomass concentrations were 3.400 g/L for no ORP control, 4.953 g/L for -150 mV ORP control and 5.260 for -100 mV ORP control. Ethanol productivities were 2.574 g/Lh for 200 g/L glucose without ORP control and 3.780 g/Lh for 200 g/L glucose with -100 mV ORP control. In 300 g/L glucose fermentation, ethanol productivity decreased to 1.584 g/Lh when no ORP control was imposed. ORP control at -150 mV could improve the ethanol productivity to 1.693 g/Lh while -100 mV ORP control was able to further enhance the ethanol productivity to 1.829 g/Lh. Fatty acid composition was observed to shift to more saturated components when no ORP control was applied. Such trend of saturation was increased by higher gravity condition. ORP control was shown to change this tendency to saturation and help restore fatty acid components on plasma membrane to a more balanced distribution.

▼ There are currently over 84,000 dams in the United States, and the average age of those dams is 52 years. Concrete gravity dams are the second most common dam type, with more than 3,000 in the United States. Current engineering technology and technical understanding of hydrologic and seismic events has resulted in significant increases to the required design loads for most dams; therefore, many older dams do not have adequate safety for extreme loading events. Concrete gravity dams designed and constructed in the early 20th century did not consider uplift pressures beneath the dam, which reduces the effective weight of the structure. One method that has been used to enhance the stability of older concrete gravity dams includes the post-tension anchor (PTA) system. Post-tensioning infers modifying cured concrete and using self-equilibrating elements to increase the weight of the section, which provides added stability. There is a lack of historical evidence regarding the potential failure mechanisms for PTA concrete gravity dams. Of particular interest, is how these systems behave during large seismic events. The objective of this thesis is to develop a method by which the potential failure modes during a seismic event for a PTA dam can be evaluated using the linear elastic finite element method of analysis. The most likely potential failure modes (PFM) for PTA designs are due to tensile failure and shear failure. A numerical model of a hypothetical project was developed to simulate PTAs in the dam. The model was subjected to acceleration time-history motions that simulated the seismic loads. The results were used to evaluate the likelihood of tendon failure due to both tension and shear. The results from the analysis indicated that the PTA load increased during the seismic event; however, the peak load in the tendons was less than the gross ultimate tensile strength (GUTS) and would not be expected to result in tensile failure at the assumed project. The analysis also indicated there was a potential for permanent horizontal displacement along the dam/foundation interface. The horizontal movement was not considered large enough to develop a shear failure of the tendons at the project. The results from this study indicate demand to capacity ratios (DCR) of 0.79 for the anchor head, 0.75 for the tendon, and 0.63 for the foundation cone failure, and a potential displacement of 0.33 inches, which is not large enough to shear the tendon. The methods developed are appropriate for the evaluation of the tensile and shear failure modes for the PTA tendons. Based on the results, it would appear that shear failure of the tendon is a more likely failure mechanism. Thus, shear failure of the tendon should be a focus of seismic evaluations.

Neste trabalho vamos investigar quais as modificaÃÃes que o potencial gravitacional com termo de Chern-Simons sofre com a adiÃÃo da teoria nÃo-comutativa no espaÃo-tempo. Faremos isto em dois casos: o primeiro utilizando somente a teoria de Einstein-Hilbert e no segundo caso acrescentando o termo de gravidade topolÃgica tipo Chern-Simons. As modificaÃÃes que estamos investigando ocorrem em um espalhamento de dois bÃsons vetoriais trocando um grÃviton. AtÃ podermos chegar a uma conclusÃo de como a nÃo comutatividade altera o potencial gravitacional, iremos iniciar nosso estudo com um modelo de gravidade em baixas dimensÃes. ApÃs apreender como calcular o propagador do grÃviton para teoria quadrÃticas da gravidade, expandimos os conceitos para uma gravidade topologicamente massiva. Revisaremos tÃpicos importantes da teoria nÃo-comutativa no espaÃo-tempo. Por fim analisando a interaÃÃo com campo do grÃviton com matÃria escreveremos o vÃrtice da teoria e encontraremos as modificaÃÃes oriundas da nÃo comutatividade dos dois casos citados acima. Verificamos que a nÃo-comutatividade altera a forma do potencial gravitacional tanto na origem, deixando-o bem comportado, quanto no infinito.

In this paper we investigate what changes the gravitational potential with Chern-Simons term suffers from the addition of the noncommutative theory in space-time. We do this in two cases: the first using only the theory of Einstein-Hilbert and in the second case, adding the term topological Chern-Simons gravity type. The changes that occur are investigating on a scattering of two vector bosons exchanging a graviton. Until we reach a conclusion as the noncommutativity changes the gravitational potential, we will begin our study with a gravity model in low dimensions. After learning how to calculate the graviton propagator for quadratic theory of gravity, we expanded the concepts for a topologically massive gravity. We will review important topics of noncommutative theory in space-time. Finally analyzing the interaction with the graviton field with matter, write the vertex of the theory and find the changes arising from the noncommutativity of the two cases cited above. We found that the noncommutativity alters the shape of the gravitational potential both in origin, leaving him well behaved, as at infinity.

▼ The objective of this study is to evaluate and compare, both technically and economically, various glucose feeding concentrations and different redox potential settings on ethanol production under very-high-gravity (VHG) conditions. Laboratory data were collected for process modeling and two process models were created by two individual process simulators. The first one is a simplified model created and evaluated by Superpro Designer. The second one is an accurate model created by Aspen Plus and evaluated by Aspen Icarus Process Evaluator (Aspen IPE). The simulation results of the two models were also compared. Results showed that glucose feeding concentration at 250±3.95 g/L to the fermentor resulted in the lowest unit production cost (1.479 /kg ethanol in the Superpro model, 0.764 /kg ethanol in the Aspen Plus model), with redox potential control effects accounted. Controlling redox potential at -150 mV increased the ethanol yield under VHG fermentation conditions while no significant influences were observed when glucose feeding concentration was less than 250 g/L. Results of product sales analysis indicated that for an ethanol plant with a production rate of 85~130 million kg ethanol/year, only maintaining the glucose feeding concentration to the fermentor at around 250 g/L resulted in the shortest payout period of 5.33 years in average,, with or without redox potential control. If 300±6.42 g/L glucose feeding concentration to the fermentor is applied, it is essential to have the redox potential only controlled at -150 mV in the fermentor to limit the process payout period within 6 years. In addition, fermentation processes with glucose feeding concentration at around 200 g/L to the fermentor were estimated to be unprofitable under all studied conditions. For environmental concerns, two disposal alternatives were presented for CO2 produced during fermentation process rather than emission into atmosphere. One is to sell CO2 as byproduct, which brought 1.52 million /year income for an ethanol plant with a capacity of 100 million kg ethanol/year. Another option is to capture and transport CO2 to deep injection sites for geological underground storage, which is already a safe and mature technology in North America, and also applicable to many other sites around the world. This would roughly add 4.78 million dollars processing cost annually in the studied scenario. Deep injection of captured CO2 from ethanol plants prevents emission of CO2 into the atmosphere, thus makes it environmental friendly.

▼ The southeastern North American margin (SENAM) is one of the world’s oldest intact passive margins, containing the ancient southern Appalachian Mountains, the South Georgia Rift (SGR), and the Central Atlantic Magmatic Province (CAMP). Potential field data is used in combination with seismic imaging, borehole data, and surface geology to better constrain the lithospheric configuration created by Appalachian orogenesis and Atlantic rifting. In combination with filtering techniques, maps and 2D potential field forward models, and Euler inverse modeling are used to illuminate the pre-Cretaceous basement including basement faults, shear zones, and granites in the hinterland of the southern Appalachians, and rift basins and mafic intrusions beneath the Atlantic coastal plain and continental shelf. Focusing on the Laurentia – peri-Gondwana suture zone, modeling confirms the importance of low-angle basement thrust faults in producing Alleghanian uplift and exhumation of metamorphic core complexes. The Appalachian paired gravity anomaly is explained by an increase in crustal thickness and a decrease in upper crustal density northwest of the Carolina superterrane, suggesting that Grenville-age basement rocks extend southeastward beneath the coastal plain. The source of the enigmatic and controversial Brunswick Magnetic Anomaly (BMA) is interpreted to be a series of late-stage rift-related mafic intrusions segmented by incipient fracture zones. This interpretation is supported by the observation that the BMA is independent and inboard of the East Coast Magnetic Anomaly, implying a pre-drift source, and that the amplitude and frequency of the anomaly change nearshore across the Blake Spur fracture zone that divides the offshore BMA, where continental breakup occurred, from the onshore BMA. Basin boundaries of the SGR were revised using tilt derivative maps of gravity and filtered magnetic data. These maps delineate the northern boundaries of the SGR in South Carolina, and suggest the existence of a class of lenticular basins peripheral to the SGR developed within the Piedmont (Carolina) magnetic terrane. A major crustal boundary between the Piedmont and Charleston-Brunswick magnetic terranes in eastern Georgia and South Carolina is proposed as the Suwannee (Alleghanian) suture. The Tifton and McClellan magnetic anomalies are interpreted to be mega-scale mafic igneous complexes, which are evidence of focused rift-related magmatism. Advisors/Committee Members: James N. Kellogg.

Докторска дисертација посвећена је моделирању густина Земљине коре у поступку одређивања гравитационог утицаја топографских маса на аномалијски потенцијал и његове функционале на територији Републике Србије. Гравитациони утицаји топографских маса одређени су на основу података дигиталног модела терена на територији Србије и глобалног модела терена SRTM (Shuttle Radar Topography Mission) за утицаје топографских маса ван граница Србије. Сагласно расположивим и релевантним подацима креиран је дигитални модел густина до геоида, док је топографским масама ван граница Србије додењена вредност константне густине ρ=2.67 g/cm3 . Све топографске масе подељенe су на праве призме правоугаоне основе, а за моделирање њиховог гравитационог утицаја примењена су два поступка: класична теренска корекција и резидуални модел терена. Моделирање утицаја топографских маса урађено је са:  густинама из дигиталног модела густина и  константном густином, ρ=2.67 g/cm3 . Анализом добијених резултата, показано је да утицај густина топографских маса није занемарљив у поступку решавања граничних проблема потенцијала Земљине теже, а посебно при одређивању геоида центиметарске тачности.

▼ The wave of globalisation gave rise to a number of regional arrangements. The notion of economic regionalism gained importance rapidly in international trade as well as regional diplomacy. The body of theoretical and empirical literature suggests that economic regionalism is beneficial for trade flows and economic welfare, but some studies find it as a stumbling block for multilateral liberalisation efforts. The fundamental analytical questions are whether the groups demonstrate significant impetus to expand intra-bloc trade and whether a preferential liberalisation within theregional arrangement results in non-trivial mutual gains. To address these queries,this thesis investigates the trade pattern, potential and effects of a comparatively newregional group, Bay of Bengal for Multi-Sectoral Technical and EconomicCooperation (BIMSTEC).To examine the trade pattern of BIMSTEC countries, it adopts an augmented panel gravity model. The results reveal that imports of the member countries follow the Linder hypothesis, while exports can be explained by Heckscher-Ohlin-Samuelson theorem. Controlling for behind and beyond the border constraints, the results of astochastic frontier gravity model also support these findings. Such constraints are found to explain most of the total variation in imports and exports. The results also suggest that the highest trade potential, estimated by the frontier gravity model, turns out to be significant. Every members of the group can substantially expand intra-BIMSTEC trade if the constraints are either removed or kept at the minimum.This thesis finally examines the possible effects of an FTA within BIMSTEC by trade policy simulation tools, Software on Market Analysis and Restrictions on Trade(SMART) and Global Trade Analysis Project (GTAP). The results of SMARTsimulations indicate that significant gains can be obtained from an FTA in terms of trade and welfare effects. Conversely, revenue effects appear to be disproportionate. Smaller members like Bangladesh, Bhutan, Myanmar, Nepal, and Sri Lanka would experience proportionately higher revenue loss compared to bigger members such asIndia and Thailand. It suggests that smaller members deserve technical support and compensation to offset negative incidences. The GTAP simulations suggest that only Bangladesh would incur a net welfare loss and a negative growth of real GDP by joining the FTA. The group as a whole would end up with a trade deficit, although India would enjoy a trade surplus. Intra-bloc trade would increase substantially in most of the sectors except for Myanmar. The simulation result also implies that despite some country-and sector-specific negative effects, the impact on overall economic growth would be positive by initiating an FTA.

Cette thèse traite de la compensation magnétique de pesanteur. Tout d’abord, des expériences de lévitation magnétique de fluides sont interprétées à l’aide d’un potentiel magnéto-gravitationnel SL. Puis, l’utilisation d’une méthode générale d’analyse de la force magnétique grâce aux harmoniques du champ magnétique est développée. Elle souligne l’importance et le rôle de chacun des trois premiers harmoniques du champ magnétique sur les configurations de forces résultantes inhérentes à la compensation magnétique de pesanteur. En géométrie cylindrique (invariante par translation) diverses combinaisons de forces d’origines magnétique, gravitationnelle et centrifuge offrent des perspectives nouvelles pour la lévitation magnétique. Une combinaison judicieuse des forces magnétiques et centrifuges permet de compenser exactement la pesanteur sur des matériaux diamagnétiques. En géométrie axisymétrique (invariante par rotation), le dimensionnement de stations de lévitation d’oxygène, techniquement réalisables ([email protected],2K), est présenté. Ces stations permettent de léviter des volumes d’oxygène supérieurs à 1 litre avec des inhomogénéités inférieures à 1%. La constitution de ces stations rend possible les variations spatiales et temporelles des configurations d’accélérations résultantes. Enfin, la compensation magnétique dynamique de gravité, à l’aide d’une station de lévitation réelle, est étudiée afin de simuler des phases d’accélération ou de décélération d’engins spatiaux

The thesis deals with magnetic gravity compensation. First of all magnetic levitation experiments are explained with the help of a magneto-gravitational potential SL. Next, a general analysis method of the magnetic force is developed which employs magnetic field harmonics. The method underlines both the significance and role of the first three magnetic field harmonics on the resulting forces inherent in magnetic gravity compensation. In cylindrical geometry – with translational invariance – various combination of magnetic, gravitational and centrifugal forces open new possibilities for the magnetic levitation. A suitable combination of both magnetic and centrifugal forces allows exactly compensating gravity on diamagnetic materials. In axisymmetric geometry – with rotational invariance – designs of feasible oxygen magnetic levitation stations are introduced ([email protected],2K). Levitation of oxygen volumes more than one litre with inhomogeneities less than 1% can be accomplished within these magnetic levitation facilities. The constitution of the stations makes possible both spatial and temporal variations of the resulting acceleration configurations. At last the dynamic magnetic compensation of gravity with a real coil system is studied so as to simulate both acceleration and deceleration of spaceships

This thesis is assessing the potential of the European rail passenger market with a 4 step model, with a gravity based trip distribution and assessment of level of service characteristics to determine total potential in demand and supply commissioned by Train2EU and Royal HaskoningDHV. The scope has been limited to long-distance (>100km) trips. The main research question is: Where and how in Europe does, currently and in 2030, the biggest potential of international train passenger travel exist, based on passenger-trip potential (demand) and seating capacity potential (supply)? A framework for potential of the current network is developed based on the passenger-trip potential and seating capacity potential, providing input for a preliminary proposal for a passenger core connections network. The passenger-trip potential is based on the classic 4-step transport model and a gravity based trip distribution including barriers as language and country borders. For the modal split and route assignment a network based on the real available network has been modelled based on direct distance, mode dependant detour factors and average speed. The seating capacity potential assesses the currently provided train connections on their effectively offered seats as the result of the performance on several key level of service indicators: frequency, travel time performance, service level, transfers and offered seats. The preliminary core network is a combination of the potential in seating capacity and passenger-trip potential. It proposes 12 new core connections providing a new international network of train connections with a high service standard. This can improve the international market size of passenger rail travel by 22% in the current situation and even 14x for the growth scenario in 2030. Additionally the amount of CO2-emmission could be reduced with 28 million tonnes

▼ In this thesis, special geodetic problems are treated as boundary value problems. Thegeodesic problem, the gravity field due to a homogeneous ellipsoid and the linearfixed altimetry-gravimetry problem are thoroughly studied in ellipsoidal geometry.The study is not limited on a biaxial ellipsoid (oblate spheroid), which is the wellknownmathematical model used in geodesy, but is extended on a triaxial ellipsoid.The key issue in the current analysis is the expression of the above problems in thesuitable ellipsoidal coordinate system.The ellipsoidal coordinate system is described in some detail. For a one-to-onecorrespondence between ellipsoidal and Cartesian coordinates two variants ofellipsoidal coordinates are introduced. The transformation between ellipsoidal andCartesian coordinates on a triaxial ellipsoid is presented in these two variants. Also,the element of distance and Laplace’s equation are expressed in these coordinates.The classical transformation between ellipsoidal and Cartesian coordinates on abiaxial ellipsoid is presented as a degenerate case.The geodesic problem on a triaxial ellipsoid is solved as a boundary valueproblem, using the calculus of variations. The boundary value problem is formulatedby means of the Euler-Lagrange equation and consists of solving a non-linear secondorder ordinary differential equation, subject to the Dirichlet conditions. Subsequently,this problem is reduced to an initial value problem with Dirichlet and Neumannconditions. The Neumann condition is determined iteratively by solving a system offour first-order ordinary differential equations with numerical integration. The lastiteration yields the solution of the boundary value problem. From the solution, theellipsoidal coordinates and the angle between the line of constant longitude and thegeodesic, at any point along the geodesic, are determined. Also, the constant inLiouville’s equation is determined and the geodesic distance between the two points,as an integral, is computed by numerical integration. To demonstrate the validity ofthe method, numerical examples are given. The geodesic boundary value problem andits solution on a biaxial ellipsoid are obtained as a degenerate case. In this case, using a special case of the Euler-Lagrange equation, the Clairaut equation is verified and the Clairaut constant is precisely determined. Also, the numerical tests are validated bycomparison to Vincenty’s method.The exterior gravity potential and its derivative induced by a homogeneoustriaxial ellipsoid are presented. Some expressions, which are used for therepresentation of the exterior gravitational potential, are mentioned. Subsequently, the λ tan-1a sa sxy όπου οι τιμές των 1 s , 2 s , 3 s υπολογίζονται από την επίλυση κατάλληλης κυβικήςεξίσωσης. Τέλος, ο κλασικός μετασχηματισμός μεταξύ ελλειψοειδών καιΚαρτεσιανών συντεταγμένων στο διαξονικό ελλειψοειδές παρουσιάζεται ως μιαεκφυλισμένη περίπτωση.Το γεωδαισιακό πρόβλημα περιλαμβάνει τον προσδιορισμό της γεωδαισιακήςμεταξύ δύο σημείων 0 0 0 P β , λ και 1 1 1 P β , λ σε ένα…
