GNSS Spoofing Detection using Two-Antenna Differential Carrier Phase

A method is developed to detect GNSS spoofing by processing beat carrier-phase measurements from a pair of antennas in a CDGPS-type calculation. This system Copyright © 2014 by Mark L.

Beta-Thalassemia Carrier Detection by NESTROFT

Hot carrier-assisted intrinsic photoresponse in graphene.

We report on the intrinsic optoelectronic response of high-quality dual-gated monolayer and bilayer graphene p-n junction devices. Local laser excitation (of wavelength 850 nanometers) at the p-n interface leads to striking six-fold photovoltage patterns as a function of bottom- and top-gate voltages. These patterns, together with the measured spatial and density dependence of the photoresponse...

GIS-Assisted Object Detection

We propose a method to improve object detection results by introducing GIS data into the fold. Our current system uses post-processing techniques on the object detection results to get rid of most of the false positive detections and acquire some of the true positives. We show that GIS data can greatly improve object detection results on images which have a GPS tag of where the image was taken ...
