Towards recovery of complex shapes in meshes using digital images for reverse engineering applications [PDF]

open access: yes, 2010
When an object owns complex shapes, or when its outer surfaces are simply inaccessible, some of its parts may not be captured during its reverse engineering. These deficiencies in the point cloud result in a set of holes in the reconstructed mesh.

Prospects and Challenges of 4H-SiC Thyristors in Protection of HB-MMC-VSC-HVDC Converters

open access: yesIEEE Open Journal of Power Electronics, 2021
Pole-to-pole DC faults on HB-MMC-VSC-HVDC schemes impose significant risk of cascade failure on IGBT/diode pairs. Other novel topologies with fault blocking capability, i.e. AAC converters, and DC circuit breakers are not yet fully matured.

A reshaping recovery: the reverse shoulder arthroplasty triumphs in salvaging chronic four-part proximal humerus fractures [PDF]

open access: yes, 2023
The aging population is witnessing a steady increase in the incidence of displaced proximal humerus fractures, particularly among elderly patients. Such fractures pose a significant challenge to orthopedic surgeons, given the complex interplay of factors

A Novel 4H-SiC SGT MOSFET with Improved P+ Shielding Region and Integrated Schottky Barrier Diode

open access: yesMicromachines
A silicon carbide (SiC) SGT MOSFET featuring a “一”-shaped P+ shielding region (PSR), named SPDT-MOS, is proposed in this article. The improved PSR is introduced as a replacement for the source trench to enhance the forward performance of the device.

Recovery Performance of Ge-Doped Vertical GaN Schottky Barrier Diodes

open access: yesNanoscale Research Letters, 2019
Vertical GaN Schottky barrier diodes (SBDs) were fabricated on Ge-doped free-standing GaN substrates. The crystal quality of the SBDs was characterized by cathode luminescence measurement, and the dislocation density was determined to be ~ 1.3 × 106 cm ...
