Gravitation und Quantentheorie. II

Heat and Gravitation. II. Stability

Some features of hydroand thermodynamics, as applied to atmospheres and to stellar structures, are puzzling: 1. The suggestion, first made by Laplace, that our atmosphere has an adiabatic temperature distribution, is confirmed for the lower layers, but the reason why it should be so is difficult to understand. 2. The standard treatment of relativistic thermodynamics does not allow for a systema...

Zur Quantentheorie des elektrischen Restwiderstandes

The influence of short-range order on the residual resistivity of Cu3Au is investigated within a formalism previously reported. As compared to analogous methods based on the Boltzmann equation, the scattering of electrons by three correlated impurity centers is included. The characteristic numbers needed to describe the short-range order between the three centers can be determined within narrow...

Equilibria und weiteres Heiteres II

We investigate several technical and conceptual questions. Our main subject is the investigation of independence as a ternary relation in the context of non-monotonic logic. In the context of probability, this investigation was started by W.Spohn et al., and then followed by J.Pearl. We look at products of function sets, and thus continue our own investigation of independence in non-monotonic l...

Analyse und Vergleich von BckR2D2-I und II

Im Oktober 2011 erregte die Veröffentlichung von Details über die inzwischen meist als BckR2D2 bezeichnete Schadsoftware öffentliches Aufsehen. Mitglieder des Chaos Computer Club e.V. veröffentlichten einen ersten Bericht über die Funktionsweise des Trojaners, dem weitere Analysen folgten. In dieser Arbeit geben wir einen Überblick über die bislang veröffentlichen Einzelberichte und über die ve...
