Advanced Statistical Crystal Plasticity Model: Description of Copper Grain Structure Refinement during Equal Channel Angular Pressing

open access: yesMetals, 2023
The grain structure of metals changes significantly during severe plastic deformation (SPD), and grain refinement is the main process associated with SPD at low homologous temperatures.

Grain Structure Rearrangement by Means the Advanced Statistical Model Modified for Describing Dynamic Recrystallization

open access: yesMetals, 2023
The study of grain and defect structure evolution in materials subjected to thermomechanical processing is still an urgent problem because the state of a structure substantially determines the physical and mechanical macro properties of polycrystals and ...

Advanced Bayesian Multilevel Modeling with the R Package brms [PDF]

open access: yesThe R Journal, 2017
The brms package allows R users to easily specify a wide range of Bayesian single-level and multilevel models, which are fitted with the probabilistic programming language Stan behind the scenes. Several response distributions are supported, of which all

MTU-Net: Multilevel TransUNet for Space-Based Infrared Tiny Ship Detection [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2022
Space-based infrared tiny ship detection aims at separating tiny ships from the images captured by Earth-orbiting satellites. Due to the extremely large image coverage area (e.g., thousands of square kilometers), candidate targets in these images are ...

Analysis and Design of High-Efficiency Modular Multilevel Resonant DC-DC Converter

open access: yesIEEE Open Journal of Power Electronics, 2022
This paper demonstrates a high-efficiency modular multilevel resonant DC-DC converter (MMRC) with zero-voltage switching (ZVS) capability. In order to minimize the conduction loss in the converter, optimizing the root-mean-square (RMS) current flowing ...
