Comparison of habitual stepping cadence analysis methods: Relationship with step counts
Gait & Posture, 2022Different approaches have been implemented to calculate stepping cadence (steps/min) that vary in the time demominator used. Given the differences in how stepping intensity are calculated, it is unclear if they are more so associated with total step counts.This study compared three methods of calculating stepping cadence and determined their ...

Stability of Two-Step Methods for Variable Integration Steps
SIAM Journal on Numerical Analysis, 1983Two of the most commonly used methods, the trapezoidal rule and the two-step backward differentiation method, both have drawbacks when applied to difficult stiff problems. The trapezoidal rule does not sufficiently damp the stiff components and the backward differentiation method is unstable for certain stable variable-coefficient problems with ...

Dangers of Multiple Time Step Methods
Journal of Computational Physics, 1993This paper discusses two potential dangers of multiple stepsize techniques for different interactions in molecular dynamics. In the first case, such techniques may not preserve the symplectic nature of the flow, so that for non-symplectic multiple time stepping instability or dissipation can occur.

The step by step development of NRW method
2011 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC 2011), 2011This paper explains in details the NRW method highlighting its mathematical procedure and analyzing the most important points and limitations to characterize the complex permittivity and permeability of dielectrics. The step by step procedure help the researchers to well understand the physical phenomenona involved and also is a tool to facilitate its ...

Comparison of 1-step and 2-step methods of fitting microbiological models
International Journal of Food Microbiology, 2012Previous conclusions that a 1-step fitting method gives more precise coefficients than the traditional 2-step method are confirmed by application to three different data sets. It is also shown that, in comparison to 2-step fits, the 1-step method gives better fits to the data (often substantially) with directly interpretable regression diagnostics and ...
