I present an Hipparcos color-magnitude diagram (CMD) that is color-coded by transverse velocity v ⊥. This illustrates the connection between the photomet-ric and kinematic properties of various stellar populations in a manner that is particularly suitable to introductory astronomy courses.

in this paper, the stability of a functionally graded magneto-electro-elastic (fg-mee) micro-beam under actuation of electrostatic pressure is studied. for this purpose euler-bernoulli beam theory and constitutive relations for magneto-electro-elastic (mee) materials have been used. we have supposed that material properties vary exponentially along the thickness direction of the micro-beam. gov...

We report a new approach for microfluidic optical bioanalysis that is based on the electrically driven assembly of bio-components on a transparent sidewall and the optical detection of the assembled components using planar waveguides. This allows localized electrical signals for bio-assembly and optical signals for bio-detection that can easily be applied in MEMS systems. We demonstrate a BioME...

ELECTRO-OCULOGRAPHY has been established as a valuable clinical procedure for measuring indirectly the standing corneo-fundal potential, of importance in the investigation of retinal and choroidal function. Although the technique of clinical recording is not very complicated, the load of a great many records is a burden for the technical staff of an electro-diagnostic clinic. Semiautomatic reco...

Der Entwurf von Steuerungen und die Trajektorienplanung für lineare Systeme mit örtlich verteilten Parametern und konzentrierten Stelleingriffen können in gewissen Fällen auf der Basis von Potenzreihendarstellungen erfolgen. Es wird eine Methode vorgestellt, mit der diese Reihendarstellungen systematisch auch für solche partiellen Differentialgleichungen hergeleitet werden können, deren Koeffiz...
