Fast introduction of new functionality into the existing telecommunication nodes is very important task for software and system designers. One effective way to do this is to move part of functionality to additional external platform. By creating generic application components and putting them together, new functionality is introduced into the network. In this paper framework for introduction of...

To aid in the functional partitioning of a system into interacting hardware and software components, fast yet accurate estimations of hardware size are crucial. We introduce a technique for obtaining such estimates in two orders of magnitude less time than previous approaches without sacriicing substantial accuracy, by incrementally updating a design model for a changed partition rather than re...

We have extended the spectral modelling of the soft X-ray background (SXRB) using the ROSAT PSPC data along several lines of galactic longitude. Our results continue to demonstrate the need for a Galactic halo component, which is shown to vary markedly as a function of position. These fluctuations significantly affect the ability to investigate variations in the extragalactic SXRB below 2 keV. ...
