Mean arterial pressure (MAP) is estimated at the brachial artery level by adding a fraction of pulse pressure (form factor; =0.33) to diastolic pressure. We tested the hypothesis that a fixed form factor can also be used at the aortic root level. We recorded systolic aortic pressure (SAP) and diastolic aortic pressure (DAP), and we calculated aortic pulse pressure (PP) and the time-averaged MAP...

Accurate characterization of an aperture synthesis radiometer requires making measurement of its performances inside an anechoic chamber. However, due to size limitations, the sources used in the process have to be located at distances too short to be able to apply the far-field condition of the instrument. Although the fundamental equation of aperture synthesis radiometry derived for far-field...

The Supergen HiDEF (Highly Distributed Energy Future) project focuses on possibilities for decentralising five features of energy systems: resources, control, network infrastructure, participation (markets and commercial arrangements) and policy. This paper concentrates on participation, and the practicalities of an ‘active demand side’. It examines four potential means of altering network and ...

Two processes are necessary to solve group decision making problems: a consensus process and a selection process. The consensus process is necessary to obtain a final solution with a certain level of agreement between the experts, while the selection process is necessary to obtain such a final solution. Clearly, it is preferable that the set of experts reach a high degree of consensus before ap...

this paper proposes improvements and revisions to a recent approach in a voting system, and provides an effective approach with a stronger discriminate power. for this purpose, the advantage of a linear transformation is utilized to redene a previously used concept of virtual worst candidate, by incorporating the existing weight restrictions. then, the best score of this virtual candidate is u...
