Current EEG research approaches are focusing on developing new dry electrode EEG (electroencephalogram) systems providing a high enough signal quality for a wide range of applications. This study proposes several parameters for evaluating signal quality of dry electrodes and relates the results to skin-electrode contact impedance magnitude values. The EEG recordings of a Ag/AgCl pinned electrod...

The major objective of this study is to develop a modelling method for estimating the biodynamic responses distributed at the fingers and the palm of the hand based on the total driving-point mechanical impedance of the entire hand-arm system. A five degrees-of-freedom (DOF) model with a set of constraints proposed in this study was used in the estimation. Three sets of mechanical impedance dat...

This article compares stochastic estimates of human ankle mechanical impedance when ankle muscles were fully relaxed and co-contracting antagonistically. We employed Anklebot, a rehabilitation robot for the ankle to provide torque perturbations. Surface electromyography (EMG) was used to monitor muscle activation levels and these EMG signals were displayed to subjects who attempted to maintain ...

parameter identification techniques are particularly attractive to determine the inertial parameters of robot manipulators and manipulated payloads. these parameters are particularly needed in implementation of a model-based controller for robot manipulators. in this paper, the inertial parameters of a manipulated rigid-body object have been estimated. the newton-euler equations will be employe...

BACKGROUND Current evaluation of pulmonary hypertension (PH) in children involves measurement of pulmonary vascular resistance (PVR); however, PVR neglects important pulsatile components. Pulmonary artery (PA) input impedance and ventricular power (VP) include mean and pulsatile effects and have shown promise as alternative measures of vascular function. Here we report the utility of pulsed-wav...

OBJECTIVE To compare three different body fats estimation equations using skin fold measurements with bioelectrical impedance analysis. METHODS A total of 130 subjects were included from Department of Endocrinology and Metabolism, Services Hospital, Lahore from 1st April 2016 to 30th Sep. 2016. The triceps, biceps, subscapular, chest, thigh, abdominal, suprailiac skinfold thickness of the sub...
