The cosmological “equation of state parameter”, w, is equal to −1 for a true cosmological constant, and is greater than −1 for quintessence. There is a widespread reluctance to consider the remaining possibility, w < −1, though in fact there is a variety of theoretical and observational evidence in favour of this range. We briefly discuss some of the objections to w < −1 and show that each of t...

www.digilogicsystems.com The Wideband IF Record & Replay System has been developed using the National Instruments PXI(e) hardware platform and LabVIEW environment. For IF inputs, PXIe 7966R with 5761 adapter is used and for IF outputs, PXIe 5451 module has been used. For the Record & Replay software, various techniques like Digital DownConversion (DDC), Digital UpConversion, Streaming of data a...

In order to be able to evaluate beforehand the impact of a strategic or tactical move so as to plan optimal strategies to reach their goals, decision makers need reliable predictive systems. What-if analysis is a data-intensive simulation whose goal is to inspect the behavior of a complex system, such as the corporate business or a part of it, under some given hypotheses called scenarios. In pa...

j Dr. Hilda Lewis and Miss Margaret Kornitzer, both well known for their work /[connection with adoption, have written this leaflet for adolescents who are worried J ?ut the fact of their adoption and their relationship with their own parents. In simple terms it expresses probable anxieties about illegitimacy and the moral .social problems involved. Reliance on the personal value of the child, ...

in some cities in the USA,6 but the general level of health consciousness and the public attitude to family medicine and emergency care are so different in the USA that it is far from clear that American experience is relevant to the United Kingdom. The number of lives that MCCUs can be expected to save in the United Kingdom is therefore small, so establishing MCCU services on a wider basis mus...

The core of the toolbox consists of a set of model-based validation components including exhaustive/interactive simulation, on-the-fly temporal logic modelchecking, test case generation and optimal path extraction. In order to control state explosion, the toolbox provides several static analysis tools operating at the source level such as live variable analysis, dead-code elimination and slicin...
