An Enhanced Evaluation Method of Sequential Probability Ratio Test

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
Accurate event detection has high priority in many technical applications. Events in acquired data series, their duration, and statistical parameters provide useful information about the observed system and about its current state. This information can be used for condition monitoring, state identification, and many kinds of forecasting as well.

Fast and Invertible Simplicial Approximation of Magnetic‐Following Interpolation for Visualizing Fusion Plasma Simulation Data

Computer Graphics Forum, Volume 44, Issue 3, June 2025.
Abstract We introduce a fast and invertible approximation for fusion plasma simulation data represented as 2D planar meshes with connectivities approximating magnetic field lines along the toroidal dimension in deformed 3D toroidal spaces. Scientific variables (e.g., density and temperature) in these fusion data are interpolated following a complex ...

Design of transverse magnetic field sweeping solenoids for 140 GHz mega‐watt gyrotrons

The Journal of Engineering, Volume 2018, Issue 14, Page 682-685, 2018., 2018
As the overlarge power density at the collector of mega‐watt (MW) gyrotrons limits the increase in their average output power and pulse width, transverse magnetic field sweeping solenoids (TMFSS) with periodical changing magnetic field have been designed for a 140 GHz MW gyrotron developed and tested at Beijing Vacuum Electronics Research Institute ...
