And the department's Web site, redesigned to make the tracking of letter-grade scores possible, attracted 74,000 cumulative page views from June 2010 to June 2011, experiencing a sevenfold increase in page views over the previous year.
Such designed controller is able to make the tracking error of joint angle of knee exoskeletons exponentially converge to zero.
Such controller is designed based on Zhang dynamics (ZD) method so as to make the tracking error of joint angle exponentially converge to zero.
The biggest challenge for the team was to make the tracking equipment - the GPS and activity sensor tags - small and light enough for domestic cats to wear around their necks on safety-release collars.
This can make the tracking of participation over a term difficult (Bean and Peterson, 1998) and such tracking might not hold up to student scrutiny if challenged (Heyman and Sailors, 2011).
In order to make the tracking process more effective and informative, after edge point detection, the edge images per frame E t are dilated by a 3 × 3 square-shaped structuring element.
