The Ontology: Chimaera or Pegasus

In the context of the needs of the Semantic Web and Knowledge Management, we consider what the requirements are of ontologies. The ontology as an artifact of knowledge representation is in danger of becoming a Chimera. We present a series of facts concerning the foundations on which automated ontology construction must build. We discuss a number of different functions that an ontology seeks to ...

Pegasus Paper 94 – 9 AudioSourceLocation

Pegasus, ESPRIT BRA 6865, is a project of the University of Cambridge and the University of Twente. The project is aimed at the design of an operating systems architecture for scalable distributed multimedia systems and the development of a validating prototype, design and implementation of a distributed complex-object service and a global name service, mechanisms for the creation, communicatio...

Pegasus: An Efficient Intermediate Representation

We present Pegasus, a compact and expressive intermediate representation for imperative languages. The representation is suitable for target architectures supporting predicated execution and aggressive speculation. In Pegasus information about the global dataflow of the program is encoded in local structures, enabling compact and efficient algorithms for program optimizations. As a proof of the...

Status of the UCLA PEGASUS Laboratory∗

The PEGASUS laboratory is a versatile radiation facility dedicated to the advancement of novel concepts in beam physics. The installation of a new LaB6 cathode will allow for both thermionic emission and photoinjection operation. The PEGASUS plane wave transformer injector has been conditioned to 20 MW of RF power. Recent operations show a 15 MeV dark current beam that will be used for beam rad...
