Building Fire Hazard Predictions Using Machine Learning

January 26, 2024
Author(s)
Eugene Yujun Fu, Wai Cheong Tam, Tianhang Zhang, Xinyan Huang
The lack of information on the fire ground has always been the leading factor in making wrong decisions . Wrong decisions can be made by individual firefighters, their local chiefs, and/or the incident commander. Any wrong decision at any level (scale)

A Smart Network Repository Based on Graph Database

January 25, 2024
Author(s)
Amar Abane, Abdella Battou, Mheni Merzouki, Tao Zhang
To address the increasing complexity of network management and the limitations of data repositories in handling the various network operational data, this paper proposes a novel repository design that uniformly represents network operational data while

Thomas W. Vetter, Colleen E. Bryan Sallee, Brian Lang, Anthony F. Marlow, Jennifer Ness, Rick L. Paul, Adam L. Pintar, Bruce Scruggs, Nicholas Sharp, Maria Isabel Vega Martinez, John Sieber
Standard Reference Material (SRM) 2693a Bituminous Coal (Nominal Mass Fraction 0.5 % Sulfur) is intended for use in the evaluation of techniques employed in the determination of sulfur, mercury, chlorine, and ash in coal and materials of a similar matrix

Intelligent Building Agents Laboratory: Air System Design

January 25, 2024
Author(s)
Amanda Pertzborn, Daniel Veronica, Glen A. Glaeser
The National Institute of Standards and Technology has constructed the Intelligent Building Agents Laboratory (IBAL) to demonstrate the potential for distributed, intelligent software agents to optimize the control of heating, ventilation, and air

Filtering Organized 3D Point Clouds for Bin Picking Applications

January 23, 2024
Author(s)
Marek Franaszek, Prem Rachakonda, Kamel S. Saidi
In many manufacturing applications, autonomous robot action is guided by a perception system integrated with the robot. The quality of the acquired 3D data must be high to ensure smooth and uninterrupted execution of robotic tasks. Unfortunately, many

Connecting Molecular Exchange Dynamics to Stress Relaxation in Phase-Separated Dynamic Covalent Networks

January 22, 2024
Author(s)
Neil Dolinski, Ran Tao, Nicholas Boynton, Anthony Kotula, Charlie Lindberg, Kyle Petersen, Aaron M. Forster, Stuart Rowan
A suite of phase separated dynamic covalent networks based on highly tunable dynamic benzalcyanoacetate (BCA) thia-Michael acceptors are investigated. In situ kinetic studies on small molecule model systems are used in conjunction with macroscopic

Reference Correlations for the Density and Thermal Conductivity, and Review of the Viscosity Measurements, of Liquid Titanium, Zirconium, Hafnium, Vanadium, Niobium, Tantalum, Chromium, Molybdenum, and Tungsten

January 22, 2024
Author(s)
Eleftheria Ntonti, Sofia Sotiriadou, Marc Assael, Marcia L. Huber, Boris Wilthan, Manabu Watanabe
The available experimental data for the density, thermal conductivity, and viscosity of liquid titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, and tungsten have been critically examined with the intention of establishing

C Rieck, T Ido, M Wouters, Y Hanado, M Fujieda, PO Hedekvist, PE Pottie, J Bartholomew, J Hanssen, A Malimon, N Ashby, P Defraigne, Elizabeth Donley, I Sesia, H Schnatz, P Dube, N Dimarc, F Levi, H Margolis, S Slyusarev, M Yasuda, S Bize, D Calonico, David B. Newell, JP Uzan, M Gertsvolf, C Oates, E Peik, S Weyers, DH Yu, G Mileti, P Tavella, F Meynadier, G Petit, G Panfilo, F Fang, J Lodewyck
This paper outlines the roadmap towards the redefinition of the second recently updated by the CCTF Task Force created by the CCTF in 2020. The main achievements and the open challenges related to the status of the optical frequency standards, their

Harmonizing the forensic nomenclature for STR Loci D6S474 and DYS612

January 21, 2024
Author(s)
Martin Bodner, David Ballard, Lisa Borsuk, Jonathan King, Walther Parson, Christopher Phillips, Katherine Gettings
The autosomal short tandem repeat (STR) locus D6S474 and the Y-chromosomal STR locus DYS612 have been reported multiple ways in the forensic literature, with differences in both the bracketed repeat structures and counting of numerical length-based

Josephson Sampler Response using a Binary Search Algorithm

January 19, 2024
Author(s)
BART VAN ZEGHBROECK, Logan Howe, Pete Hopkins
This paper presents the use of a binary search algorithm to obtain the simulated response of a superconducting Josephson junction-based sampler. In the absence of noise, this simple approach is superior to mimicking the experimental approach of using an

Continuous Mobile Manipulator Performance Measurement Data

January 18, 2024
Author(s)
Joshua D. Kneifel, David Webb, Luke Donmoyer
The Engineering Laboratory (EL) of the National Institute of Standards and Technology (NIST) has developed a variety of tools that provide some level of economic analysis, many of which have been developed by EL's Applied Economics Office (AEO). AEO

Autonomous cementitious materials formulation for critical infrastructure repair

January 17, 2024
Author(s)
Howie Joress, Rachel Cook, Austin McDannald, Mark Kozdras, Jason hattrick-simpers, Aron Newman, Scott Jones
Despite the long history of cement and concrete, there are still large gaps in fundamental knowledge of their properties development. The dire need for improved cementitious repair materials, requires a revolution in the way they are formulated and tested
