Sommario/riassunto |
|
Jochen Oltmer bietet einen umfassenden Überblick über Hintergründe, Formen und Folgen von Migration in Deutschland seit dem späten 18. Jahrhundert. Die komplett überarbeitete und aktualisierte Neuauflage reicht nun bis in die Gegenwart und stellt den gegenwärtigen Stand einer Forschung dar, die seit den 1990er Jahren rasch an Fahrt gewonnen hat. Eine umfangreiche, thematische gegliederte Bibliographie schließt den Band ab. |
Jochen Oltmer presents a comprehensive overview of the background, forms, and consequences of migration to Germany since the 18th century. This completely updated and revised new edition extends to the present time and describes the latest status of research on migration, a field that has rapidly expanded since the 1990s. The book concludes with a detailed thematically structured bibliography. |

Sommario/riassunto |

This Brief investigates the intersections that occur between three different areas of study that normally would not touch each other: ODF, spline theory, and topology. The Least Squares Orthogonal Distance Fitting (ODF) method has become the standard technique used to develop mathematical models of the physical shapes of objects, due to the fact that it produces a fitted result that is invariant with respect to the size and orientation of the object. It is normally used to produce a single optimum fit to a specific object; this work focuses instead on the issue of whether the fit responds continuously as the shape of the object changes. The theory of splines develops user-friendly ways of manipulating six different splines to fit the shape of a simple family of epiTrochoid curves: two types of Bézier curve, two uniform B-splines, and two Beta-splines. This work will focus on issues that arise when mathematically optimizing the fit. There are typically multiple solutions to the ODF method, and the number of solutions can often change as the object changes shape, so two topological questions immediately arise: are there rules that can be applied concerning the relative number of local minima and saddle points, and are there different mechanisms available by which solutions can either merge and disappear, or cross over each other and interchange roles. The author proposes some simple rules which can be used to determine if a given set of solutions is internally consistent in the sense that it has the appropriate number of each type of solution. |
