Intelligence Level Performance Standards Research for Autonomous Vehicles

October 1, 2015
Author(s)
Roger V. Bostelman, Tsai H. Hong, Elena R. Messina
U.S. and European safety standards have evolved to protect workers near Automated Guided Vehicles (AGV's). However, only recently performance standards have begun development for AGV's and mobile robots. Lessons can be learned for developing such a

Low noise kinetic inductance traveling-wave amplifier using three-wave mixing

October 1, 2015
Author(s)
Michael R. Vissers, Robert P. Erickson, Leila R. Vale, Xian Wu, Gene C. Hilton, David P. Pappas
We have fabricated a wide-bandwidth, high dynamic range, low noise cryogenic amplifier based on a superconducting kinetic inductance traveling-wave device. The device was made from NbTiN and consisted of a long, coplanar waveguide on a silicon chip. By

Peer-to-Peer Urban Channel Characteristics for Two Public-Safety Frequency Bands

October 1, 2015
Author(s)
Catherine A. Remley, David W. Matolak, Camillo A. Gentile, Christopher L. Holloway, Qiong Wu, Qian Zhang
We report on ground-based wireless channel characteristics for an urban environment in two public safety bands. Results are based upon measurements taken in Denver in June 2009. The public safety bands we investigated are the 700 MHz and 4.9 GHz bands

Research highlights: Probing adsorbed organic coatings on nanoparticle surfaces

October 1, 2015
Author(s)
Stacey M. Louie, John M. Pettibone
Organic coatings adsorbed at a nanoparticle surface, together with the system properties, change the physicochemical properties of the nanoparticle, thereby possibly modifying its behavior and interactions with its surroundings. A detailed understanding of

Self-powered p-NiO/n-ZnO heterojunction ultraviolet photodetectors fabricated on plastic substrates

October 1, 2015
Author(s)
Ratan K. Debnath, MD R. Hasan, Ting Xie, Sara C. Barron, Guannan Liu, Nhan V. Nguyen, Abhishek Motayed, M V. Rao
A self-powered ultraviolet (UV) photodetector (PD) based on p-NiO and n-ZnO was fabricated using low-temperature sputtering technique on indium doped tin oxide (ITO) coated plastic polyethylene terephthalate (PET) substrates. The fabricated devices showed

Spreading alerts quietly and the subgroup escape problem

October 1, 2015
Author(s)
J. Aspnes, Z. Diamadi, A. Yampolskiy, K. Gjosteen, Rene Peralta
We introduce a new cryptographic primitive called a blind coupon mechanism (BCM). In effect, a BCM is an authenticated bit commitment scheme, which is AND-homomorphic. We show that a BCM has natural and important applications. In particular, we use it to
