Journal ArticleDOI
Spatio-temporal parameters of gait measured by an ambulatory system using miniature gyroscopes
TL;DR: An ambulatory system for estimation of spatio-temporal parameters during long periods of walking based on wavelet analysis to compute the values of temporal gait parameters from the angular velocity of lower limbs, which is light, portable, inexpensive and does not provoke any discomfort to subjects.
Journal ArticleDOI
Ambulatory system for human motion analysis using a kinematic sensor: monitoring of daily physical activity in the elderly
TL;DR: The ambulatory system showed a very high accuracy (> 99%) in identifying the 62 transfers or rolling out of bed, as well as 144 different posture changes to the back, ventral, right and left sides, in both first and second studies.
Journal ArticleDOI
Measurement of stand-sit and sit-stand transitions using a miniature gyroscope and its application in fall risk evaluation in the elderly
TL;DR: In this study, the wavelet transform has provided a powerful technique for enhancing the pattern of PT, which was mainly concentrated into the frequency range of 0.04-0.68 Hz.
Journal ArticleDOI
Equilibrium and transport properties of the noble gases and their mixtures at low density
TL;DR: In this article, a set of easy-to-program expressions for the calculation of the thermodynamic and transport properties of the five noble gases (He, Ne, Ar, Kr, Xe) and of the 26 binary and multicomponent mixtures that can be formed with them are presented.
Journal ArticleDOI
Capturing human motion using body-fixed sensors: Outdoor measurement and clinical applications
Kamiar Aminian,Bijan Najafi +1 more
TL;DR: The possibility to detect useful human motion based on new techniques using different types of body‐fixed sensors is shown and a combination of accelerometers and angular rate sensors (gyroscopes) showed a promising design for a hybrid kinematic sensor measuring the 2D kinematics of a body segment.
