Geodesy is the science of measuring and mapping the geometry, orientation and gravity field of the Earth including the associated variations with time. Geodesy has also provided the foundation for high accuracy surveying and mapping. Modern Geodesy involves a range of space and terrestrial technologies that contribute to our knowledge of the solid earth, atmosphere and oceans. These technologie...

This paper generalizes the notion of symmetrical neighbourhoods, which have been used to define connectivity in the case of sets, to the wider framework of complete lattices having a sup-generating family. Two versions (weak and strong) of the notion of a symmetrical dilation are introduced, and they are applied to the generation of “connected components” from the so-called “geodesic dilations”...

Results are presented from 22.1 pb -l of T(lS) data, taken with the Crystal Ball detector at DORIS. These data were taken to further explore the ~(8.3) signal originally seen in 10.4 pb -l of T(lS) data!2l No evidence for the < is observed in this new sample. Data quality checks and possible explanations are discussed. l Work supported by the Department of Energy, contract DEAC03-76SFOO515 Cont...

Geodesy is the science of measurement or mapping of the properties of the Earth’s surface. A good example of an interesting problem in geodesy is the gravitation acceleration g(λ) on earth as a function of the latitude λ = π/2 − θ. (The angle θ in spherical coordinates is sometimes called the co-latitude angle.) For background, also read Marion # 10-7 and 10-20. Newton already suggested in Prin...

Several months before the outbreak of the First World War, a new piece of popular musical theatre opened at the Gaiety Theatre in London’s West End. After the Girl told the story of Doris Pitt, the daughter of a Cincinnati millionaire sent to Brussels to complete her education. When her father arrives on a visit in Paris, he finds her ‘corrupted’ and determines to send her back home. Doris, how...
