Analysis of a Slug Calorimeter with a Curie Point

April 3, 2020
Author(s)
Jiann C. Yang, Thomas J. Ohlemiller
A lump-capacitance heat transfer model was developed to model the operation of a slug calorimeter constructed of metal with a Curie point. The resulting formula has been successfully used to infer total heat flux to a metal structural member in a fire by

Improving 3D Vision-Robot Registration for Assembly Tasks

April 3, 2020
Author(s)
Marek Franaszek, Geraldine S. Cheok, Karl Van Wyk, Jeremy A. Marvel
Quality registration between the coordinate frames of a perception system and a robot is important for the efficient operation of autonomous systems in vision-guided assembly lines. Rigid-body registration, which is based on the measurement of

Strategic Roadmap for Interoperable Public Safety Video Analytics

April 3, 2020
Author(s)
Diane E. Ridgeway
Since 9/11, the Department of Homeland Security has provided over $16 billion dollars in grant assistance to secure cities and non-profit organizations against terrorist and disaster incidents. In order to meet the threat demands, public safety

Streaming Batch Gradient Tracking for Neural Network Training

April 3, 2020
Author(s)
Siyuan Huang, Brian D. Hoskins, Matthew W. Daniels, Mark D. Stiles, Gina C. Adam
Faster and more energy efficient hardware accelerators are critical for machine learning on very large datasets. The energy cost of performing vector-matrix multiplication and repeatedly moving neural network models in and out of memory motivates a search

A Multi-Band Rydberg-Atom Based Receiver/Antenna: AM/FM Stereo Reception

April 2, 2020
Author(s)
Christopher L. Holloway, Matthew T. Simons, Joshua A. Gordon
With the re-definition of the International System of Units (SI) that occurred in October of 2018, there has recently been a great deal of attention in the development atom-base sensors for metrology applications. In particular great progress had been made

On the Nature of Macroradicals Formed upon Radiolysis of Aqueous Poly(N--?vinylpyrrolidone)Solutions

April 2, 2020
Author(s)
Richard D. Holbrook, Clelia Dispenza, Maria Antonietta Sabatino, Natascia Grimaldi, Bjorn Dahlgren, Mohamad Al-Sheikhly, James F. Wishart, Zois Tsinas, Mats Jonsson
In this work we have explored the nature of macroradicals formed upon radiolysis of aqueous poly(N-­‐vinylpyrrolidone) (PVP) solutions using pulse radiolysis, density functional theory (DFT) and literature data. On the basis of literature data on site-­

An Entropy Scaling Demarcation of Gas- and Liquid-like Fluid Behaviors

April 1, 2020
Author(s)
Ian H. Bell, Guillaume Galliero, Stephanie Delage-Santacreu, Lorenzo Costigliola
In this work we propose a generic and simple definition of a line separating gas-like and liquid-like fluid behaviors in the supercritical region. We argue that this line is defined by the location of the minimum of the macroscopically scaled viscosity

Benchmarking Protocols for Evaluating Grasp Strength, Grasp Cycle Time, Finger Strength, and Finger Repeatability of Robot End-effectors

April 1, 2020
Author(s)
Joseph A. Falco, Daniel Hemphill, Kenneth E. Kimble, Elena R. Messina, Adam Norton, Rafael F. Ropelato, Holly A. Yanco
This paper describes a set of metrics and supporting benchmarking protocols for determining the performance characteristics of robot end-effectors. In the short-term, these tools are proving useful as a common ground for assessing and comparing end

Benchmarking Protocols for Evaluating Small Parts Robotic Assembly Systems

April 1, 2020
Author(s)
Kenneth Kimble, Joseph Falco, Elena R. Messina, Karl Van Wyk , Yu Sun, Mizuho Shibata, Wataru Uemura, Yasuyoshi Yokokohji
This paper presents a set of performance metrics, test methods, and associated artifacts to help progress the development and deployment of robotic assembly systems. The designs for three task board artifacts that replicate small part insertions and

Discovering Mathematical Objects of Interest - A Study of Mathematical Notations

April 1, 2020
Author(s)
Howard S. Cohl, Andre Greiner Petter, Moritz Schubotz, Corinna Breitinger, Fabian Muller, Akiko Aizawa, Bela Gipp
Mathematical notation, i.e., the writing system used to communicate concepts in mathematics, encodes valuable information for a variety of information search and retrieval systems. Yet, mathematical notations remain mostly unutilized by today's systems. In
