New Perspectives on Stability of Decoupled Double Synchronous Reference Frame PLL
IEEE transactions on power electronics, 2021Modeling and interpretation of synchronization stability of energy conversion systems with the unbalanced grid is a very practical, complicated, and less explored topic.

PI-Based Synchronous Reference Frame Frequency-Locked Loop
IEEE transactions on industrial electronics (1982. Print), 2021A novel proportional–integral (PI)-based frequency-locked loop (FLL) is proposed and verified in this letter. Unlike the conventional FLL, which is implemented in the stationary (αβ) reference frame, the proposed PI-based FLL (PI-FLL) is implemented in ...

Vector Field Topology of Time-Dependent Flows in a Steady Reference Frame
IEEE Transactions on Visualization and Computer Graphics, 2020The topological analysis of unsteady vector fields remains to this day one of the largest challenges in flow visualization. We build up on recent work on vortex extraction to define a time-dependent vector field topology for 2D and 3D flows. In our work,

Deep Network-Based Frame Extrapolation With Reference Frame Alignment
IEEE transactions on circuits and systems for video technology (Print), 2020Frame extrapolation is to predict future frames from the past (reference) frames, which has been studied intensively in the computer vision research and has great potential in video coding.

The referent of the frame of reference
The Psychological Record, 1963Just as research has demonstrated that judgment and perception of objects and events are influenced by the frame of reference, we need to explore the precise relationship between the “view and point of view.” Just what features are and are not affected by a particular frame of reference? What features remain constant and invariant?

The solution to a mechanical problem begins with the kinematic analysis, the analysis of how a system can move, as opposed to how it actually does move under the influence of a particular set of forces. In this first stage, the essential step is the introduction of coordinates to label the configurations of the system.

Synthese, 1970
In philosophy we are sometimes interested in the invariants of intelligibility. What do all good (adequate, successful, fair) interpretations of a language, or of a person, have in common? What common reality is projected by our understanding of each other?2 What do persons share that makes communication possible?

Enhanced Motion-Compensated Video Coding With Deep Virtual Reference Frame Generation
IEEE Transactions on Image Processing, 2019In this paper, we propose an efficient inter prediction scheme by introducing the deep virtual reference frame (VRF), which serves better reference in the temporal redundancy removal process of video coding.
