Research on Peak‐to‐Average Power Ratio Control Method for Switched Reluctance Pulse Generator
Addressing the different requirements for peak output power when SRPG supplies power to pulse loads and DC loads, the peak‐to‐average power ratio (PAPR) is taken as the generation performance optimisation parameter. By investigating the power characteristics of the SRPG, the influence of control parameters on the PAPR is studied.

Electron microscopic measurement of the size of the optical focus in laser scanning microscopy [PDF]
We describe a method for measuring the lateral focal spot size of a multiphoton laser scanning microscope (LSM) with unprecedented accuracy. A specimen consisting of an aluminum film deposited on a glass coverslip was brought into focus in a LSM and the ...

Quadratic‐boost‐double‐flyback converter [PDF]
Combining low‐voltage power sources with loads that require high‐voltage levels is a challenge, especially for power devices above 500 W. In this context, this study presents a new dc–dc high‐gain converter using coupled inductors. The new converter uses only one switch and output capacitors with low values.

Steady‐state free precession for T2* relaxometry: All echoes in every readout with k‐space aliasing
Abstract Purpose Multi‐echo gradient echo imaging is useful for a range of applications including relaxometry, susceptibility mapping, and quantifying relative proportions of fat and water. This relies primarily on long‐TR multi‐echo gradient echo sequences (FLASH), which by design isolate one signal component (i.e., echo) at a time per readout.

Dielectric Barrier Discharge Electrothermal Heating and Additive Manufacturing of Thermoset Parts
3D printing of thermosets is difficult due to the low yield stress of most uncured resins. However, by locally heating resin using a non‐equilibrium plasma, layers can be partially cured and printing enabled. Plasma application to a liquid epoxy/carbon nanotube composite is observed to cause rapid surface heating and oxidation of the cured layers ...
