A spatially developing flat-plate boundary layer free from and two-way coupled with inertial solid particles is simulated to investigate the interaction between turbulent/non-turbulent interface. Particle Stokes numbers based on outer scale are $St=2$ (low), 11 (moderate) 53 (high). The Eulerian–Lagrangian point-particle approach deployed for simulation of particle-laden flow. edge interface detected as an iso-surface vorticity magnitude. Results show that tend accumulate below due...

They diagnosed as USpA based rheumatologists' findings. Correlations between HLA-B27 status or MRI...
<h3>Objective</h3> This paper analyses helmet use before and after implementing Helmets for Kids, a school-based distribution road safety programme in Cambodia. <h3>Methods</h3> Nine intervention schools (with total of 6721 students) four control 3031 were selected using purposive sampling to target where students at high risk traffic injury. Eligible included those least 50% commute school on bicycles or motorcycles, located national (high density), had few no street signs nearby, an area...
In this paper, wall-resolved large-eddy simulation of turbulence, Lagrangian point-force model particle tracking, and two-way coupling approach are used to simulate the particle-laden flow over a rigid wall. The is turbulent open channel with particle-free friction Reynolds number Reτ=4200. Together simulated results an erodible bed from Zheng et al. [J. Fluid Mech. 918, 1–27 (2021)], influence lower boundary condition motion wall-normal gravity on turbulence modulation thoroughly compared....
Abstract This brief paper emphasizes on the experimental study of a hybrid contact model combining traditional physical-based and data-driven error in order to provide more accurate description dynamics phenomenon.

A bouncing ball experiment designed performed validate model. can duplicate...
Space manipulators which have a similar symmetrical structure with seven revolute joints, such as the space station remote manipulator system (SSRMS), can be called SSRMS-type manipulators. The analytical inverse kinematics of an solved by locking single joint; locked joint (joint 1, 2, 6, or 7) determined configuration analysis. Although widely used in establishing manipulators, Denavit-Hartenberg (DH) method has singular problem when two adjacent axes are nearly parallel. To avoid this...
Spatial markers can be used to not only complete coordinate transformation between two or more different Cartesian systems, but also provide the error evaluation of above transformation. On one hand, a group transforming is responsible for accurate parameters i.e. rotation matrix and translation vector; on other checking quantify accuracy results by Euclidean distance markers. In this article, an invalidation relative has been concluded proven that indexes are always constant because...
