Classifying human leg motions with uniaxial piezoelectric gyroscopes
(2009)This paper provides a comparative study on the different techniques of classifying human leg motions that are performed using two low-cost uniaxial piezoelectric gyroscopes worn on the leg. A number of feature sets, extracted ... -
Human activity recognition using inertial/magnetic sensor units
(2010)This paper provides a comparative study on the different techniques of classifying human activities that are performed using body-worn miniature inertial and magnetic sensors. The classification techniques implemented and ... -
Mathematical modeling of the plasma frequency-height profile of the ionosphere for HF communications
(IEEE Computer Society, 2014)The plasma frequency - height profile of the ionosphere has an important impact on sky-wave HF communications. In this study, the profile obtained over a geographical region is fit to linear and spherical plane models by ... -
Range based sensor node localization in the presence of unknown clock skews
(2013)We deal with the positioning problem based on two-way time-of-arrival (TW-TOA) measurements in asynchronous wireless sensor networks. The optimal estimator for this problem poses a difficult global optimization problem. ...
