The aim of this pilot study was to investigate the feasibility and effectiveness of a new psychoeducative intervention program (PEGASUS) for adults with ADHD and their significant others in a psychiatric outpatient context. At three outpatient psychiatric clinics, adults with ADHD and their significant others took part in PEGASUS, a psychoeducational program based on theories from cognitive beh...

In this paper, we described the benefits and the challenges of integrating existing scientific workflow technologies into science gateways. Scientific workflow managers are powerful tools for handling large computational tasks. Domain scientists find it difficult to create new workflows, so many tasks that could benefit from workflow automation are often avoided or performed by hand. Two techno...

As scientific applications in a variety of disciplines are being actively studied and computing environments become more complicated and dynamic, a challenge is how to leverage existing cyber-infrastructures and achieve robust and efficient computing. This paper presents a case study on planning and executing application workflows over provisioned resources. This work integrates the Pegasus wor...

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...

Multimedia applications place new demands upon processors, networks and operating systems. While some network designers, through ATM for example, have considered revolutionary approaches to supporting multimedia, the same cannot be said for operating systems designers. Most work is evolutionary in nature, attempting to identify additional features that can be added to existing systems to suppor...
