  • Analysis of orientation error of triaxial accelerometers on the assessment of energy expenditure 
    Wang Lu; Su Steven; Celler Branko; Ambikairajah E. (IEEE, 2005)
    This paper investigates the effects of orientation error in the positioning of triaxial accelerometers on the assessment of energy expenditure. Four subjects walked on a treadmill at varying velocities ranging from 4km.h-1 ...
  • Estimation of walking energy expenditure by using Support Vector Regression 
    Su Steven; Wang Lu; Celler Branko; Savkin Andrey; Ambikairajah E. (IEEE, 2005)
    This paper develops a new predictor of walking energy expenditure from wireless measurements of body movements using triaxial accelerometers. Reliable data were collected from repeated walking experiments in different ...
  • Heart rate control during treadmill exercise 
    Su Steven; Wang Lu; Celler Branko; Savkin Andrey (IEEE, 2005)
    A computer-controlled treadmill and related data collection and processing systems have been developed for the control of heart rate during treadmill exercise. Minimizing deviations of heart rate from a preset profile is ...
  • Modeling of a gas concentration measurement system 
    Wang Lu; Su Steven; Celler Branko; Savkin Andrey (IEEE, 2005)
    Energy expenditure can be calculated via measurement of oxygen consumption and carbon dioxide production. Precise measurement of expired gas concentrations and volume is required for this determination. For a given gas ...
