Diophantine approximation on Veech surfaces [PDF]
, 2010 We show that Y. Cheung's general $Z$-continued fractions can be adapted to give approximation by saddle connection vectors for any compact translation surface. That is, we show the finiteness of his Minkowski constant for any compact translation surface.

A VSC-based Model for Power Flow Assessment of Multi-terminal VSC-HVDC Transmission Systems [PDF]
Journal of Modern Power Systems and Clean Energy, 2021 This paper puts forward a new practical voltage source converter (VSC) based AC-DC converter model suitable for conducting power flow assessment of multi-terminal VSC-based high-voltage direct current (VSC-MTDC) systems. The model uses an advanced method to handle the operational limits and control modes of VSCs into the power flow formulation. The new
