Prediction Accuracy of Dynamic Mode Decomposition

open access: yesSIAM Journal on Scientific Computing, 2020
Dynamic mode decomposition (DMD), which the family of singular-value decompositions (SVD), is a popular tool of data-driven regression. While multiple numerical tests demonstrated the power and efficiency of DMD in representing data (i.e., in the interpolation mode), applications of DMD as a predictive tool (i.e., in the extrapolation mode) are scarce.

Current Collapse-Free and Self-Heating Performances in Normally Off GaN Nanowire GAA-MOSFETs

open access: yesIEEE Journal of the Electron Devices Society, 2018
Normally off lateral GaN nanowire gate-all-around MOSFETs have been fabricated on the GaN-on-insulator substrate. The dynamic measurement proved that the devices with various nanowire heights exhibit current collapse-free characteristics implying that ...
