The Force-Velocity Profile for Jumping: What It Is and What It Is Not. [PDF]
Med Sci Sports Exerc, 2023 ABSTRACT Introduction Force–velocity profiling has been proposed in the literature as a method to identify the overall mechanical characteristics of lower extremities. A force–velocity profile is obtained by plotting for jumps at different loads the effective work as a function of the average push-off velocity ...

Reliability of the Squat Jump Force-Velocity and Load-Velocity Profiles [PDF]
Journal of Strength & Conditioning Research, 2021 Abstract Kotani, Y, Lake, J, Guppy, SN, Poon, W, Nosaka, K, Hori, N, and Haff, GG. The reliability of the squat jump force-velocity and load-velocity profiles. J Strength Cond Res 36(11): 3000–3007, 2022—The purpose of this study was to investigate the between-session reliability of the squat jump force-velocity (FV) and load-velocity (LV ...

Interpretation of velocity profiles of the mantle [PDF]
Journal of Geophysical Research, 1975 The purpose of this note is to demonstrate that recent V_p and V_s profiles are consistent with finite strain extrapolations of reasonable mineralogies. The difference in the size of the discontinuities in the V_p and V_s profiles is due to the relative pressure insensitivity of shear velocity in spinel structures.

Investigation of a Negative Step Effect on Stilling Basin by Using CFD
Entropy, 2022 The negative-step stilling basin is an efficient and safe energy dissipator for high-head, large-unit discharge high-dam projects. However, studies of the effects of the negative step on the hydraulic performance of a high-dam stilling basin have not ...

Universality of the Turbulent Velocity Profile [PDF]
Physical Review Letters, 2017 For nearly a century the universal logarithmic behaviour of the mean velocity profile in a parallel flow was a mainstay of turbulent fluid mechanics and its teaching. Yet many experiments and numerical simulations are not fit exceedingly well by it, and the question whether the logarithmic law is indeed universal keeps turning up in discussion and in ...

Geophysical Research Letters, 2023 Surging debris flows are among the most destructive natural hazards, and elucidating the interaction between coarse‐grained fronts and the trailing liquefied slurry is key to understanding these flows. Here, we describe the application of high‐resolution

Method for estimating pulsatile wall shear stress from one‐dimensional velocity waveforms
Physiological Reports, 2023 Wall shear stress (WSS)—a key regulator of endothelial function—is commonly estimated in vivo using simplified mathematical models based on Poiseuille's flow, assuming a quasi‐steady parabolic velocity distribution, despite evidence that more rapidly ...

Near-wall velocity profile measurement for nanofluids
AIP Advances, 2016 We perform near-wall velocity measurements of a SiO2–water nanofluid inside a microchannel. Nanoparticle image velocimetry measurements at three visible depths within 500 nm of the wall are conducted.

Velocity profiles of Osipkov–Merritt models [PDF]
Monthly Notices of the Royal Astronomical Society, 1995 A simple algorithm is presented for the calculation of the projected line-of-sight velocity profiles (VPs) of non-rotating anisotropic spherical stellar dynamical models with a phase-space distribution function of the Osipkov-Merritt type. The velocity distribution in these models is isotropic inside the anisotropy radius r_a and becomes increasingly ...
