Arne Bjerhammar
Arne Bjerhammar (September 15, 1917 – February 6, 2011) was a List of Swedish scientists, Swedish geodesy, geodesist. He was professor at Royal Institute of Technology (KTH) in Stockholm. He was born in Båstad, Scania in the south of Sweden. He developed a method used to determine the geoid in gravimetry, gravimetric data, as well as a system for electro-optical measuring of distances. He also did research about the Fennoscandian post-glacial rebound. Research His research covered many fields of geodesy. As a result of his doctor’s dissertation “A contribution to the methods of optical distance measuring, specially with regard to the problems of automatic plotting“ and for his refinement of the modulation system of the Swedish Electronic distance meter, EDM instrument ''Geodimeter'' he became one in the record of Swedish inventors. However, many geodesists (and mathematicians) know him for the first time for his new matrix algebra with generalized inverses, published in ...

Båstad
Båstad () is a Urban areas in Sweden, locality and the seat of Båstad Municipality, Scania County, Sweden, with approximately 5,000 permanent residents. It is however one of Sweden's most typical summer resorts. The population is presumably more than twice as large between April and September, and even larger during July. Its municipality follows a similar pattern: some 15,000 permanent residents, but more than 30,000 during July. Some villages within the municipality are almost empty during the winter, but have more than 2,000 "summer guests" during July. Torekov is a good example of this. Within Sweden, Båstad is well known for tennis. The largest centre court in Sweden is located in the town's centre, and can take more than 5,000 attendants. Several top national players, such as Björn Borg, Mats Wilander and Stefan Edberg, have played tennis in Båstad. Geography The town of Båstad is located in a sheltered bay with the Hallandian ridge stretching behind it. The town bord ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Post-glacial Rebound
Post-glacial rebound (also called isostatic rebound or crustal rebound) is the rise of land masses after the removal of the huge weight of ice sheets during the last glacial period, which had caused isostatic depression. Post-glacial rebound and isostatic depression are phases of glacial isostasy (glacial isostatic adjustment, glacioisostasy), the deformation of the Earth's crust in response to changes in ice mass distribution. The direct raising effects of post-glacial rebound are readily apparent in parts of Northern Eurasia, Northern America, Patagonia, and Antarctica. However, through the processes of ''ocean siphoning'' and ''continental levering'', the effects of post-glacial rebound on sea level are felt globally far from the locations of current and former ice sheets.Milne, G.A., and J.X. Mitrovica (2008) ''Searching for eustasy in deglacial sea-level histories.'' Quaternary Science Reviews. 27:2292–2302. Overview During the last glacial period, much of northern Eu ...

Rossby Prize
Carl-Gustaf Arvid Rossby ( 28 December 1898 – 19 August 1957) was a Swedish-born American meteorologist who first explained the large-scale motions of the atmosphere in terms of fluid mechanics. He identified and characterized both the jet stream and the long waves in the westerlies that were later named Rossby waves. Biography Carl-Gustaf Rossby was born in Stockholm, Sweden. He was the first of five children born to Arvid and Alma Charlotta (Marelius) Rossby. He attended Stockholm University, where he developed his first interest in mathematical physics. Rossby came into meteorology and oceanography while studying geophysics under Vilhelm Bjerknes at the Geophysical Institute, University of Bergen in Bergen, Norway, during 1919, where Bjerknes' group was developing the groundbreaking concepts that became known as the Bergen School of Meteorology, including theory of the polar front. He also studied at the University of Leipzig and at the Lindenberg Observatory (''Meteoro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Geodetic Survey
The National Geodetic Survey (NGS) is a List of federal agencies in the United States, United States federal agency that defines and manages a national coordinate system, providing the foundation for transportation and communication; mapping and charting; and a large number of applications of science and engineering. Since its foundation in its present form in 1970, it has been part of the National Oceanic and Atmospheric Administration (NOAA), of the United States Department of Commerce. History The National Geodetic Surveys history and heritage are intertwined with those of other NOAA offices. It traces its history to the Survey of the Coast, which was formed in 1807 as the first scientific agency of the United States Government. It became the United States Coast Survey in 1836 and the United States Coast and Geodetic Survey in 1878, the latter name change reflecting the increasing role of geodesy in its work. Upon the creation of NOAA in 1970, the Coast and Geodetic Survey w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Molodensky
Mikhail Sergeevich Molodenskii (russian: Михаил Серге́евич Молоденский, – November 12, 1991) was a Soviet physical geodesist. He was once said to be "probably the only geodesist who would have deserved a Nobel prize". He graduated from Moscow State University (1936), since 1946 he worked for the ''Institute of Earth Physics'' (Институт Физики Земли АН СССР). He created an original theory for determining the figure of the Earth and its gravity field based on measurements done on the topographic surface, built the first Soviet gravimeter, developed a theory of the nutation of Earth. He won the Stalin Prize (1946 and 1951) and the Lenin Prize (1961). His legacy includes the Molodensky transformations, which are commonly used to transform between geodetic datums. His main work (since 1932) was on the geoid and its exterior gravity field or geopotential. His aim was to develop hypothesis-free methods for determining both the gr ...

Generalized Inverses
In mathematics, and in particular, algebra, a generalized inverse (or, g-inverse) of an element ''x'' is an element ''y'' that has some properties of an inverse element but not necessarily all of them. The purpose of constructing a generalized inverse of a matrix is to obtain a matrix that can serve as an inverse in some sense for a wider class of matrices than invertible matrices. Generalized inverses can be defined in any mathematical structure that involves associative multiplication, that is, in a semigroup. This article describes generalized inverses of a matrix A. A matrix A^\mathrm \in \mathbb^ is a generalized inverse of a matrix A \in \mathbb^ if AA^\mathrmA = A. A generalized inverse exists for an arbitrary matrix, and when a matrix has a regular inverse, this inverse is its unique generalized inverse. Motivation Consider the linear system :Ax = y where A is an n \times m matrix and y \in \mathcal R(A), the column space of A. If A is nonsingular (which implies n ...
