Author(s)
Mitchell R. Woodside, Patrick Bazzoli, Philip A. Olubodun, J. Adam Nisbett, Helen Qiao, Douglas A. Bristow
While there are many works developing methods for modeling and calibrating robot kinematics, assessing the accuracy of those models has received little attention. However, accuracy assessment is critically important for applications where the robot must

Blueprint for Deploying 5G O-RAN Testbeds: A Guide to Using Diverse O-RAN Software Stacks

October 23, 2024
Author(s)
Peng Liu, Kyehwan Lee, Fernando Cintron, Simeon Wuthier, Bhadresh Savaliya, Douglas Montgomery, Richard Rouil
This documentation serves as a blueprint for new researchers, offering a comprehensive guide on establishing an Open Radio Access Network (O-RAN) testbed from scratch. It details the O-RAN architecture and the supporting software stacks required for each

Microstructure and mechanical properties of laser powder bed fusion Ti-6Al-4V after HIP treatments with varied temperatures and cooling rates

October 22, 2024
Author(s)
Nicholas Derimow, Jake Benzing, Howard Joress, Austin McDannald, Ping Lu, Frank DelRio, Newell Moser, Matthew Connolly, Alec Saville, Orion Kafka, Chad Beamer, Ryan Fishel, Chris Hadley, Nikolas Hrabe
This work investigated non-standard HIP cycles for PBF-L Ti-6Al-4V and characterized microstructure and tensile properties to compare between material that originated from the same build. For 920 °C, faster cooling rates (100 °C/min, 2000 °C/min) were

Measuring Post-Disaster Accessibility to Essential Goods and Services: Proximity, Availability, Adequacy, and Acceptability Dimensions

October 21, 2024
Author(s)
Amin Enderami, Elaina Sutley, Jennifer Helgeson, Leonardo Duenas-Osorio, Maria Watson, John van de Lindt
Rapid restoration of access to essential goods and services has long been regarded as paramount for community recovery. Yet, there remains ambiguity in how access should be defined, measured, or operationalized. Defining accessibility as the ability to use

NIST Cybersecurity Framework 2.0: Enterprise Risk Management Quick-Start Guide

October 21, 2024
Author(s)
Stephen Quinn, Victoria Pillitteri, Matthew Barrett, Matthew Smith, Gregory Witte
This guide provides an introduction to using the NIST Cybersecurity Framework (CSF) 2.0 for planning and integrating an enterprise-wide process for integrating cybersecurity risk management information, as a subset of information and communications

NIST Cybersecurity Framework 2.0: Quick-Start Guide for Using the CSF Tiers

October 21, 2024
Author(s)
Stephen Quinn, Cherilyn Pascoe, Matthew Barrett, Karen Scarfone, Gregory Witte
This Quick-Start Guide describes how to apply the CSF 2.0 Tiers. CSF Tiers can be applied to CSF Organizational Profiles to characterize the rigor of an organization's cybersecurity risk governance and management outcomes. This can help provide context on

Deformation of PMMA samples in cone calorimeter and anaerobic gasification experiments

October 20, 2024
Author(s)
Karen De Lannoye, Isaac Leventon, Lucie Hasalova, Alexander Belt, Ernst-Arndt Reinecke, Lukas Arnold
16 Cone calorimetry and anaerobic gasification experiments are often used to assess material 17 flammability of bench-scale (coupon sized) samples in response to well-characterized external radiant 18 heating. In this project, it has been observed that the
