Classification of normal gait from pathological gait as then can be used as indicator of falling among subjects requires the correct choice of sensor location in the insole. Such a flexi force-sensor can be used underneath foot to measure vertical ground reaction force. To start with, the most relevant information (parameters) that can characterize the recorded signals are extracted from the vertical ground reaction force signals. Then Receiver Operating Characteristic curve is used to evaluate the features upon 8 sensors underneath each foot located at different locations. To confirm results obtained, features are passed upon a chosen classifier, in this paper K-nearest neighbors algorithm is chosen. Results show that the sensor located at the inner arch of the sole of the foot (i.e. at the mid foot) holds the most relevant information needed for better classification compared to other sensors.
Radiation efficiency and impedance bandwidth of conductor-backed CPW-fed broadside twin slot antennas on two-layer dielectric substrate, IEE Proc Microw Antennas Propag 150 (2003), 185-190. 9. A.U. Bhobe, C.L. Holloway, M.P. May, and R. Hall, Wide-band slot antennas with CPW feed lines: hybrid and log-periodic designs, IEEE ABSTRACT: A directive antenna fed by a rectangular waveguide termination is presented in this paper. The antenna consists of a radiating slot associated with a focusing system made of a series of high-dielectric slabs and air, forming successive Fabry-Perot cavities. Antenna gains as high as 19 dBi are obtained in this way, which can be used in microwave and millimeter-wave links. Several antennas, based on a different number of cavities, have been built and tested at the center frequency of 38.9 GHz.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
