Download Leitbilder in den Sozialwissenschaften: Begriffe, Theorien by Katharina D. Giesel PDF

By Katharina D. Giesel

Der Leitbildbegriff avanciert derzeit zu einer neuen sozialwissenschaftlichen Kategorie. Katharina D. Giesel befasst sich mit den Fragen, used to be in den verschiedensten Sozialwissenschaften unter Leitbildern verstanden wird, wie diese Kategorie konzeptionell in Forschungs- und Handlungskonzepte eingebunden wird und inwiefern Leitbilder eine zeitgemäße Kategorie der Sozialwissenschaften darstellen. Auf diese Weise gibt die Autorin dem derzeit verhältnismäßig diffusen Leitbildansatz der Sozialwissenschaften ein konsistentes begriffliches, theoretisches und konzeptionelles Fundament und schafft eine substanzielle Grundlage für die sozialwissenschaftliche Leitbildforschung.

Download German Battleships 1914-18 (1): Deutschland, Nassau and by Gary Staff, Paul Wright PDF

By Gary Staff, Paul Wright

Supported through legit files, own money owed, legit drawings and especially commissioned art, this quantity is an enlightening heritage of the Deutschland to Osfriesland sessions. Detailing the final of the pre-dreadnaught battleship sessions, this booklet is going directly to clarify the innovative advancements that came about in the German Imperial military as they readied themselves for conflict. This integrated developing vessels with huge raises in measurement and armament. This account of layout and know-how is supplemented through person send histories detailing wrestle adventure entire with first-hand bills. The particularly commissioned paintings additionally brings this heritage to existence with recreations of the battleship Pommern combating at Jutland and ships of the Osfriesland category destroying HMS Black Prince in a dramatic night-time engagement.

Download Sedimentation kleiner, schwerer Partikel durch eine Ebene, by Dreier T.M. PDF

By Dreier T.M.

Theoretical version calculations of particle-laden shear layers (Martin and Meiburg [1994] and Raju and Meiburg [1994]) have proven that debris acquire at the outer edge of vortex constructions and for that reason the particle focus is diminished within the centre of the eddies. The exam of this particle redistribution is the vital factor of the current study.In order to enquire this redistribution phenomenon experimentally, a suitable move needed to be produced. Fur this function an experimental facility which produced a normal blending layer displaying the common two-dimensional vortex buildings used to be outfitted and tested.A new circulation size approach used to be built to degree at the same time, yet independently the rate fields of the particle and fluid levels on the similar location.Subsequently, an image-processing regimen, known as least-square-matching, used to be utilized in order to calculate the neighborhood, affine transformation parameters from the experimentally detected double frames of the particle and fluid levels. extra exercises for overview have been made on hand for picking the speed fields from those parameters. in addition, the least-square-matching allowed additionally to enquire the divergence (two-dimensionality) and the vorlicity within the blending layer (in specific within the presence of sediment particles).The experiments established for the 1st time the influence expected by way of Martin and Meiburg 11994] and Raju and Meiburg [1994] providing that the debris acquire at the outer edge of vortex buildings resulting in a lessen within the particle focus within the centre of the eddies after which a settling in band-like buildings alongside the blending layer.in addition, the validity o( the Maxey and Riley [1993] equation, which describes the movement of the debris provided that the particle part is dilute, may be proven for a blending layer outdoor the accumulative zones.

Download Kooperationsanreize in selbstorganisierenden by Philipp Obreiter PDF

By Philipp Obreiter

Für Informationssysteme haben die Selbstorganisation und Autonomie der Teilnehmer große Bedeutung gewonnen. Ein solches procedure ist beispielsweise ein Ad-hoc Netz einer Universität, in dem sich die Geräte von Studenten untereinander Dienste erbringen. Aus der Sicht menschlicher Benutzer ergibt sich aber ein großes challenge: Die untereinander autonomen Geräte sind in der Lage zu betrügen, indem sie versprochene Dienstleistungen nicht erbringen. In diesem Buch wird ein Ansatz beschrieben, der solches Betrugsverhalten durch die Bereitstellung geeigneter Kooperationsanreize unterbindet.
