An initial velocity of 10 m/s was adopted to simulate low-velocity impact which was the focus in this study. For all cases used in this study, the width D of the impactor was 100 mm, its total length was 150 mm, while its mass was 64 kg per mm (in the out-of-plane direction)...
IR: insulin resistance; LDL: low-density lipoprotein; PP: pulse pressure; PWV: pulse wave velocity; RCDB: Randomized Controlled Doble-Blind; RCSB: Randomized Controlled Single-Blind; T2D: type 2 diabetes; TG: triglycerides; TNF-α: tumour necrosis factor-α; VLDL: very low density lipoprotein....
We consider a fluid flow whose velocity u is a solution to the incompressible Navier–Stokes equation $${\partial }_{t}{\boldsymbol{u}}+({\boldsymbol{u}}\cdot \nabla ){\boldsymbol{u}}=-\nabla p+\nu {\nabla }^{2}{\boldsymbol{u}}+{\boldsymbol{f}},\quad \nabla \cdot {\bol...
7), and, therefore, vf is approximately equal to the average fluid velocity in the tube. In this formulation, the origin of the z-axis is the ground electrode, and γ0 is the distance to the bulk plasma-afterglow boundary. We note that all experiments were performed in Ar and to be ...
The article under review deals with the regularity of the hy- drodynamic pressure π in the Navier–Stokes equations ∂tu − Δu + u · ∇u + ∇π = f, div u = 0 (1.1) with initial value u0 for the velocity field u = u(t, x) at time t = 0 and with vanishing ...
...“hydrogen in the comet might undergo a D+D fusion process on impact producing neutrons that would make 14C in the atmosphere, but this seems unlikely unless the comet’s velocity were extraordinary.” “Another possibility is that the impacting object was ejected by a recent near-Earth su...
velocity\({u}^{* }\)[m/s], representing the intensity of the flow near the surface. Particle-surface interaction is described by threshold friction velocity\({u}_{{th}}^{* }\), when exceeded, particle break the bond24. Breaking the bond does not mean that particle enters the main ...
In Section 4, the high velocity impact response and energy absorption capability of monolithic, double-layered plates and sandwich plate with steel skins and aluminum foam core was investigated by numerical method based on quasi-static compression experimental results. The paper can provides the basis...
Each symbol corresponds to an individual participant, with blue symbols indicating those with ankle foot orthosis (AFO) and red symbols representing participants with an additional thigh shell during the night (AFOTS). For bilateral involvement, the more severely affected side is presented. The ...
000 Hz and filtered by a 600-class butterworth filter. Data from the second accelerometer was integrated once to determine velocity and integrated twice to determine displacement. Force was calculated by multiplying the acceleration data by the mass of the impactor (F=ma). The results from this ...
