Research ArticleOpen accessIn the keywordsRotation Center Fitting based on Rotation Hybrid Calibration MethodYi Guo, Doudou Lei, Yu Liu, Baolong LiuLine laser rotation scanning can obtain accurate full contour information of the object with non-destructive testing. The key point in this process is the calibration rotation center. The calibration of the rotation center is mainly obtained through the characteristics of circles. Existing calibration schemes lead to a holed or over-gathered result. In order to solve this problem, this paper proposes … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 10 Sep 2020 · 6,342 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHardening Effects of In-Situ Aging for a Laser Welded Maraging SteelMilton Sergio Fernandes de Lima, Rafael Humberto de Mota Siqueira, Sheila Medeiros de Carvalho, Antonio Jorge AbdallaMaraging steels are ultra-high strength alloys which have been successfully laser welded to obtain structural components. For most of the applications these steels are in an aged state to attain tensile strength up to 1.5 GPa, although welding induces local softening due to dissolution of precipitates. This paper aims to investigate the effect of in-situ aging of the maraging steel … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 12 Nov 2019 · 7,210 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUnderstanding Hybrid Additive Manufacturing of Functional DevicesSantosh Kumar Parupelli, Salil DesaiThe fabrication of electronic components in three-dimensional space is critical for building multifunctional devices. Traditional manufacturing approaches are limited to building planar device configurations. In order to address this limitation, our group has developed a novel hybrid additive manufacturing process that can deposit multi-material patterns on conformal substrates. This direct-write approach involves the combination of microextrusion, pico jet and laser … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 20 Mar 2017 · 8,154 accessesView PDF Cite

EditorialOpen accessIn the abstractThe Proton Radius PuzzleG. M. HuberOccasionally,“revolutions” are caused in physics when new measurement techniques becomeavailable and cause us to rethink what we thought we knew. This has recently happenedin the field of proton structure physics, where researchers have had to revisitfundamental assumptions used in their determinations of the proton's meanelectric charge radius. Until 2010, ourknowledge of the proton's electric charge radius came exclusively fromelectron-proton interactions. … …Physics International, Vol. 6, Issue 1 · 12 Sep 2015 · 8,321 accessesView PDF Cite
