PURPOSE To assess the ability of headless compression screws to maintain immobile bony contact throughout wrist cycling following simulated 4-corner arthrodesis. Our hypothesis was that the screw constructs would not permit displacement of the carpal bones and, therefore, could tolerate early postoperative range of motion in vivo. METHODS Using 6 matched-paired cadaveric arms, 4-corner arthro...

Biomedical data, such as MRI, MEG, EEG or optical imaging data, present a challenge to any data processing software. Feature point detection has many parameters such as edge detection, corner detection and blob detection (region of interest). Compression technique is used to reduce the size of image over selected region over medical image. So that it will helpful to transfer over WLAN. This pap...

Hypersonic flow over a two-dimensional compression corner with Mach number of 7.7 and unit Reynolds 4.2 × 10 6 m ?1 is numerically investigated. Special emphasis given to the onset global instability respect three-dimensional perturbations. Global stability analysis performed for various ramp angles wall temperatures. It found that shock-induced separated system becomes unstable when angle beyo...

Numerical results are presented for the shock-boundary layer interactions in a hypersonic flow over a sharp leading edge compression corner. In this study, a second- order Godunov type scheme based on solving a Generalized Riemann Problem (GRP) at each cell interface is used to solve thin shear layer approximation of laminar Navier-Stokes (N-S) equations. The calculated flow-field shows general...

Hypersonic flow over a two-dimensional compression corner is investigated using computational fluid dynamics and global resolvent analysis in this study, which continuation of the work done by Hao et al. ( J . Fluid Mech. , vol. 919, 2021, p. A4). The same baseline free-stream conditions with Mach number 7.7 unit Reynolds 4.2 × 10 6 m −1 are considered. ramp angles range from 0° (equivalent to ...
