Ueber den Veränderlichen 93. 1901 Sagittae

Hippokrates Ueber die Krankheiten III

irrelevant. Chemistry and the relations between science, technology, and industry are well surveyed by Crosland and Cardwell respectively. Forbes's essay on mathematical cosmography is not a comprehensive account but the story (albeit interesting) of a few German cartographers. Compared with other recent collections of essays in the history of science, this volume parades no party line: witness...

Inhaltlich entkoppelte Kommunikation in heterogenen, veränderlichen Netzwerktopologien

The main concept of spontaneous smart environments is to have the devices surrounding a user work together to provide assistence to that user. To allow this spontaneous cooperation of applications in a heterogeneous application and communication landscape a communication middleware is necessary that provides specific decoupling characteristics. Existing taxonomies are not adequate to classify t...

WZ Sagittae as a DQ Herculis star

We argue that quiescent WZ Sge is a rapidly spinning magnetic rotator in which most of the matter transfered from the secondary is ejected from the system. Assuming that the observed 27.87 s oscillation period is due to the spinning white dwarf we propose that the other observed principal period of 28.96 s is a beat due to reprocessing of the rotating white dwarf beam on plasma blobs in Kepleri...

Unusual State in V Sagittae

It has been recently demonstrated that the recurring high/low states in the peculiar binary V Sge can be explained by considering the limit-cycle oscillation involving negative feedback by the wind on the mass-transfer from the secondary star. We noticed, from the recent observations reported to the VSNET, the presence of a different state of recurring variations (recurrence time ∼ 30 d) showin...
