The eclipsing Cataclysmic Variable GS Pavonis: Evidence for disk radius changes

We have obtained differential time series photometry of the cataclysmic variable GS Pavonis over a timespan of 2 years. These show that this system is deeply eclipsing (~2-3.5 mag) with an orbital period of 3.72 hr. The eclipse depth and out-of-eclipse light levels are correlated. From this correlation we deduce that the disk radius is changing and that the eclipses in the low state are total. The derived distance to GS Pav is 790+/-90 pc, with a height above the galactic plane of 420+/-60 pc. We classify GS Pav as a novalike system.Comment: 4 pages, including 2 figures, accepted for publication in A&A Letter

Active Business Objects (ABOs): A novel paradigm for building (and using!) Business Information System

The ABO project aims in the design and development an agent platform where mobile agents represent business processes. These agents encapsulate the policies, business practices and models of different business activities (like order management, payroll, warehouse and stock control). The aim of ABO is to provide a new paradigm of Business Information System design and use
