Systems and Methods for Determining Water-Cut of a Fluid Mixture
(2017-03-02)
Provided in some embodiments are systems and methods for measuring the water content (or water-cut) of a fluid mixture. Provided in some embodiments is a water-cut sensor system that includes a T-resonator, a ground conductor, and a separator. The T-resonator including a feed line, and an open shunt stub conductively coupled to the feed line. The ground conductor including a bottom ground plane opposite the T-resonator and a ground ring conductively coupled to the bottom ground plane, with the feed line overlapping at least a portion of the ground ring. The separator including a dielectric material disposed between the feed line and the portion of the ground ring overlapped by the feed line, and the separator being adapted to electrically isolate the T-resonator from the ground conductor.

Provided herein are methods for catalytically hydrogenating carbon dioxide to produce oxygenated hydrocarbons and catalysts for use in same.
Channel assessment scheme
(2017-08-22)
A source node in a multihop network determines whether to transmit in a channel based on whether the channel is occupied by a packet transmission with a large number of relays; whether the source node is in the data tones back-off zone; and the source node is in the busy tone back-off zone.
