The CHEOPS mission

CHEOPS: A Transit Photometry Mission for ESA’s Small Mission Programme

Ground based radial velocity (RV) searches continue to discover exoplanets below Neptune mass down to Earth mass. Furthermore, ground based transit searches now reach milli-mag photometric precision and can discover Neptune size planets around bright stars. These searches will find exoplanets around bright stars anywhere on the sky, their discoveries representing prime science targets for furth...

User Adaptivity on WWW through Cheops

In this paper, we present some developments of Cheops, a package that can be used by WWW designers to provide their hyperdocument with adaptivity and navigational aids. Previous version of Cheops, presented in Ferrandino et al. (1997)], is implemented by several CGI-BIN scripts that enables an HTTP server to interact with a user and adapt its responses to her behaviour. Solution is transparent ...

CHEOPS: Adaptive Hypermedia on World Wide Web

Because of stateless characteristics of http, it is not possible for http servers to adapt responses on the basis of previous interactions with the same user. Although eecient, this is a limiting aspect of the protocol, particularly for Web documents that are directed toward a broad audience, including experts and novices and an adaptive response would be helpful in providing information with t...

sash -- A stand-alone Shell for the CHEOPS-Kernel

Developing software for stand-alone environments requires the availability of an interactive test support at an early stage of work. But rough conditions close to hardware force the test support to be content with minimal assistance by infrastructure. Sash (stand-alone shell) is the test support for developing the CHEOPS-Kernel and is presented in this paper. Sash is based on a yacc-grammar and...
