Guardone, Alberto (author), Colonna, Piero (author), Pini, M. (author), Spinelli, Andrea (author)The gas dynamics of single-phase nonreacting fluids whose thermodynamic states are close to vapor-liquid saturation, close to the vapor-liquid critical point, or in supercritical conditions differs quantitatively and qualitatively from the textbook gas dynamics of dilute, ideal gases.

van Dijk, M.P. (author), Hoozemans, Marco J.M. (author), Berger, M.A.M. (author), Veeger, H.E.J. (author)In wheelchair sports, there is an increasing need to monitor mechanical power in the field. When rolling resistance is known, inertial measurement units (IMUs) can be used to determine mechanical power. However, upper body (i.e., trunk) motion affects the mass distribution between the small front and large rear wheels, thus affecting rolling...journal article 2024
