Quiescent and Flaring Structure in Rs Cvn

VLA multifrequency observations of RS CVn binaries

We present multiepoch Very Large Array (VLA) observations at 1.4 GHz, 4.9 GHz, 8.5 GHz and 14.9 GHz for a sample of eight RS CVn binary systems. Circular polarization measurements of these systems are also reported. Most of the fluxes observed are consistent with incoherent emission from mildly relativistic electrons. Several systems show an increase of the degree of circular polarization with ...

A probable RS CVn star which sometimes stops its eclipses ⋆

We report the discovery of a new variable star, called S 10947 Aql, as the likely optical counterpart of RX J2009.8+1557. The optical variability pattern as well as the detected X-ray emission suggest that it is a chromospherically active binary of the RS Canum Venaticorum (≡ RS CVn) type. We discovered an occasional disappearance of the eclipsing minima as well as large variations in the eclip...

The Small Project Observatory

Maintenance is an important activity in software engineering with studies attributing it more than 75% of the total cost of a system. More than half the time dedicated to maintenance is spent on reverse engineering the code which often is the only accurate source of information. In this context, among the many approaches, software visualization tools have long been seen as an important asset to...

The PEAK Project

The PEAK project at the University of Alberta is a radical attempt to understand world knowledge in terms of a minimal ontology of sensori-motor experience. Experience is defined as the time sequence of low-level signals passing back and forth between the AI agent and its world at some relatively fast rate, say 100 times a second. The signals passing from the world to the agent are termed sensa...
