The Skynet 5 system will provide military satellite communications to all three UK armed services, and is to be procured as a ‘private finance initiative’ (PFI). Though there are many PFI projects across all parts of the public sector, this is the first time that such an approach has been taken for providing military satellite communications. On 26 February 2002, the Ministry of Defence announc...

Due to the development of the internet and cable nets information services are going to be widely used. On the basis of projects for the development of information services like regional information services or shopping services we develop a method for the creation of information systems and services to be used through diierent nets. The approach is based on the codesign of data, dialogues and ...

A software tool for the prediction of the aero-thermodynamic environments of conceptual aerospace configurations is presented. The vehicle geometry is defined using unstructured, triangulated surface meshes. For subsonic Mach numbers a fast, unstructured, multi-pole panel code is coupled with a streamline tracing formulation to define the viscous surface solution. For supersonic and hypersonic ...

Conceptual design is a process of creating functions, forms and behaviors. Although cognitive processes are utilized in the development of new ideas, conventional methodologies do not take human cognition into account. However, it is conceivable that if one could determine how cognitive processes are stimulated, then more effective conceptual design methods could be developed. In this paper, we...

Systematic approaches for the invention of conceptual chemical process designs have been proposed and discussed for more than twenty-five years, and have now been developed to the point of industrial application. Process synthesis has also now become an integral part of many chemical engineering design curricula. CACHE has contributed to the promotion and advancement of conceptual design and pr...

The main accelerator system of the proposed research facility FAIR is the two stage synchrotron complex SIS100/300, consisting of two separate synchrotron accelerators with equal circumferences. SIS100/300 shall provide beams of protons and heavy ions with high intensities and high energies. The existing GSI accelerators UNILAC and SIS18 shall serve as injector for SIS100/300. SIS100 will be de...

The creation and manipulation of conceptual shapes need different modeling techniques from what are available in present CAD systems. Conceptual modeling techniques are supposed to provide more flexible interaction and mimic working with true materials. Therefore, this paper proposes a new computer internal modeling technique that supports the natural ways of exteriorizing shape concepts as wel...

EADOCS (expert assisted design of composite structures) is a multi-level conceptual design system, in which case-based reasoning is applied to quantify a qualitative prototype solution. Design specifications and targets for case-based retrieval comprise functional requirements, preferred and prototype solutions. Specified design problems cannot be decomposed into tractable subproblems for the r...

The data exploitation system described within is being designed to take advantage of the existence of terabytes (or more) of data sets that have been sent down from various Air Force satellites that can be used to detect previously unknown anomalies that occurred while the satellites were operational. This wealth of information can then be used and exploited to build more reliable and robust fu...
