The objective is to investigate the effectiveness of the jerk index, a derivative of acceleration with respect to time, as a kinetostatic measure for assessment of surgical performance.
With respect to the index of heart rate accelerations per time interval, there was a trend towards higher heart rate accelerations during noise exposure (8.9 ± 15.3 vs.13.5 ± 25.5; p = 0.059).
The CMT-BCS algorithm exploits the group sparsity between the real and imaginary parts of the sparse entries, ℜ u(n)) and I u(n)), and the solution of u(n)= ℜ (u(n)) + j I u(n)) converges to a K-sparse solution, whose indices correspond to estimates of acceleration of the K ground moving targets, a ̂ ( k ) = â x ( k ), â y ( k ), 0 T, where k = 1,⋯,K.
However, consistently within each breeding stage, mean vectorial dynamic body acceleration (an index of energy expenditure) was greater in years of poorer breeding success (increased by a factor of three to eight), suggesting birds were working harder within their range.
The difference in performance time between both tests (at 15 m and 30 m respectively) was used as an index of subject's ability to produce acceleration, i.e. lesser difference implies higher acceleration capacity.
We finally calculated an index of activity, the Overall Dynamic Body Acceleration (ODBA, see [17] for details of the calculation), using the acceleration values for day (average between 2 6 PM) and night (6 10 PM).
We calculated the "amount of overall movements per 24 hrs" from all motion-induced acceleration as an index of hypokinesia, "gait cycle and cadence" from the gait signals as indexes of step length, and "gait acceleration range" as an index of step power.
Undetermined parameters of acceleration model were estimated, and life indices under normal stress condition were extrapolated and compared with those from normal stress test.
But some economists saw the consumer price index's acceleration in February as a sign of a broader problem in China that could be harder to fix.
