Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

A really inertial platform for highest sensitivity instruments needing to be absolutely free from any disturbances like drag and other forces in space is proposed for the case of an equivalence principle test with differential accelerometers. A spin-stable platform, inside a corotating outer spacecraft shielding it, constitutes the reference proof mass for a simple position servo system. Position measurements, as well as signal transmissions, are achieved optically. Power is supplied by microwave beams. The proposed ambient temperature EP-mission E¨otv¨os in an 800 km equatorial orbit would constitute a simple, very economic experiment. Limitations to the potentially very high precision are expected to be set by thermal disturbances.
