Notes on the margin of stability [PDF]
Journal of Biomechanics, 2023 The concept of the 'extrapolated center of mass (XcoM)', introduced by Hof et al. (2005, J. Biomechanics 38 (1), p. 1-8), extends the classical inverted pendulum model to dynamic situations. The vector quantity XcoM combines the center of mass position plus its velocity divided by the pendulum eigenfrequency.

Cartel Stability by a Margin [PDF]
SSRN Electronic Journal, 2018 We study cartel stability when firms maintain collusion only if it is more profitable than competition by a sufficiently large margin. Accounting for an (endogenous) cartel margin suggests new unambiguous comparative statics of changes in market characteristics on the scope for stable cartels.

Effect of Power System Flexible Operation on Static Stability Margin
Taiyuan Ligong Daxue xuebao[Purposes] In the new type of power system, the high percentage of new energy connected to the grid and the complex and variable load demand make the flexibility become the focus of grid operation, but the impact on the static stability of the system ...

A new perspective on the walking margin of stability. [PDF]
J Appl Biomech, 2014 There remains a pressing need for a stability metric that can reliably identify fall susceptibility during walking, enabling more effective gait rehabilitation for reduced fall incidence. One available metric is the maximum margin of stability (MOSmax), which is calculated using the body’s center of mass (COM) position and velocity along with the ...

Online monitoring of voltage stability margin using PMU measurements [PDF]
, 2020 With the growing smart grid concept it becomes important to monitor health of the power system at regular intervals for its secure and reliable operation. Phasor Measurement Units (PMUs) may play a vital role in this regard.

Biotropia: The Southeast Asian Journal of Tropical Biology, 2011 Net Primary Production, NPP, is one of the most important variables characterizing the performance of an ecosystem. It is the difference between the total carbon uptake from the air through photosynthesis and the carbon loss due to respiration by living ...

Novel Approach to Analyze All-Round Kinematic Stability During Curving Steps
IEEE Access, 2023 From the viewpoint of the stability of biped walking, the stability for both anteroposterior, lateral, and diagonal directions should be considered owing to the frequent occurrence of turning and curving motions in the daily environment. In this study, a

Evidence for Marginal Stability in Emulsions
Physical Review Letters, 2016 We report the first measurements of the effect of pressure on vibrational modes in emulsions, which serve as a model for soft frictionless spheres at zero temperature. As a function of the applied pressure, we find that the density of states D(omega) exhibits a low-frequency cutoff omega*, which scales linearly with the number of extra contacts per ...

Frontiers in Human Neuroscience, 2021 BackgroundEffective training of the backward step response could be beneficial to improve postural stability and prevent falls. Unpredicted perturbation-based balance training (PBT), widely known as compensatory-step training, may enhance the fear of ...
