Short-wave infrared compressive imaging of single photons

June 6, 2018
Author(s)
Thomas Gerrits, Daniel Lum, Varun B. Verma, John Howell, Richard P. Mirin, Sae Woo Nam
We present a short-wave infrared (SWIR) single photon camera based on a single superconducting nanowire single photon detector (SNSPD) and compressive imaging. We show SWIR single photon imaging at a megapixel resolution with a low signal-to-background

Securing Tomorrow's Information through Post-Quantum Cryptography

February 27, 2018
Author(s)
Dustin Moody, Larry Feldman, Gregory A. Witte
In recent years, there has been a substantial amount of research on quantum computers - machines that exploit quantum mechanical phenomena to solve mathematical problems that are difficult or intractable for conventional computers. If large-scale quantum

Hybrid Datafication of Maintenance Logs from AI-Assisted Human Tags

January 15, 2018
Author(s)
Thurston B. Sexton, Michael P. Brundage, Michael L. Hoffman, Katherine C. Morris
One of the main challenges of applying AI to some datasets derives from the datasets themselves being unstructured, unclear, and ambiguous. Furthermore, the insights that are to be gained reflect the quality of the data itself; if the data is skewed, so

One-Pass Graphic Approximation of Integer Sequences

December 18, 2017
Author(s)
Brian D. Cloteaux
A variety of network modeling problems begin by generating a degree sequence drawn from a given probability distribution. If the randomly generated sequence is not graphic, we give a new approach for generating a graphic approximation of the sequence. This

Automatic Localization of Casting Defects with Convolutional Neural Networks

December 11, 2017
Author(s)
Ronay Ak, Max Ferguson, Yung-Tsun T. Lee, Kincho H. Law
Automatic localization of defects in metal castings is a challenging task, owing to the rare occurrence and variation in appearance of defects. Convolutional neural networks (CNN) have recently shown outstanding performance in both image classification and

The odd-even invariant and Hamiltonian circuits in tope graphs

October 27, 2017
Author(s)
Yvonne Kemper, James F. Lawrence
Questions of the existence of Hamiltonian circuits in the tope graphs of central arrangements of hyperplanes are considered. Connections between the existence of Hamiltonian circuits in the arrangement and the odd-even invariant of the arrangement are
