The Weak Discrepancy and Linear Extension Diameter of Grids and Other Posets [PDF]

, 2012
A linear extension of a partially ordered set is simply a total ordering of the poset that is consistent with the original ordering. The linear extension diameter is a measure of how different two linear extensions could be, that is, the number of pairs ...

A robust back-stepping stabilization scheme for virtual synchronous generators in weak grids

, 2015
This paper presents a new control scheme for virtual synchronous generators connected to weak grids. The proposed approach consists of two major parts. The first part holds a cooperative linear and nonlinear controller in order to emulate the synchronous

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Synchronous stability analysis and enhancement method for grid connected inverters in weak grids

Scientific Reports
Renewable energy resources (RESs) are typically integrated into the utility grid through grid-connected inverters (GCIs). Such a system may lose synchronization during grid faults, especially under weak grid conditions, resulting in instability problems or even triggering large-scale power outage accidents.
