Restricted by the hardware, the projection number at a single phase for 4D-CBCT imaging is very low or even less than 10, thus the associated reconstruction by using conventional reconstruction algorithms will be constrained by serious streak artifacts and noises. To address this problem, in this paper, we are aiming to develop an approach to reconstruct the 4D-CBCT image with multi-phase projections,...
Rectifier transformer is typical ac-dc converter for improving power quality by reducing the harmonic in ac mains and ripples in dc output. The design of rectifier transformer is difficult because it originates from the experience of designers. So a designer who is lack of experience would result in a waste of material and cost. In order to reduce the manufacturing cost of rectifier transformer, this...
A coilgun is an electromagnetic launcher based on electromagnetic induction. The projectile with a heavy load can be accelerated to a high speed. The currents that flow through the driving coils and the projectile would produce joule losses. All of the properties are drastically determined by the geometry and power of a coilgun. This paper aims to optimize the geometry and power parameters of the...
