in this paper, a novel technique on friction aided deep drawing using tapered blank holder divided into eight segments is proposed to overcome defect of friction aided deep drawing using four segments tapered blank holder technique. a taper blank holder is designed to be of two parts: stationary part with 5 degree taper angle and moving parts divided into eight tapered segments. the main functi...

Conventional OPAs incorporating a diffraction grating were mainly developed to achieve two-dimensional spot beam-based scan, which inevitably requires wide range of wavelength tuning, leading unaffordable complexity and limited scanning speed. In this study, we demonstrate hybrid OPA that capitalizes on silicon nitride line beam emitter based tapered waveguides array, facilitates efficient exhi...

The tapered angles of an artery significantly influence the local hemodynamics. However, as gravity is considered, little is known about the effect of tapered angles on the hemodynamics. In this study, we explored whether the effect of tapered angles on the distribution of blood flow pressure (DBFP) differed with gravity considered or not. Numerical simulations of the DBFP in a single vessel we...
