Author(s)
Zenn Roberts, Aaron Hagerstrom, Cole Gray, Angela Stelson, Vincent Neylon, Christian Long
The National Institute of Standards and Technology (NIST) maintains the United State's primary standards for traceable RF and mm-wave power measurements. These measurements require special sensors that carry no active electronics, and that have operating

Using Commercial Source Measure Units for Traceable RF Power Measurements

September 4, 2024
Author(s)
Cole Gray, Aaron Hagerstrom, Zenn Roberts, Christian Long
Abstract—As a National Metrology Institute (NMI), the National Institute of Standards and Technology (NIST) maintains traceable measurement capabilities for a variety of quantities, including microwave power. At NMIs and calibration laboratories, traceable

Current State and Emerging Trends in Advanced Manufacturing: Part 2 - Smart Systems and Future Challenges

Takeshi Matsui, Po-Hsiang Hung, Han Mei, Xianan Liu, Fangfei Li, John Collins, Weiyi Li, Darach Miller, Neil Wilson, Esteban Toro, Geoffrey Taghon, Gavin Sherlock, Sasha Levy
To reduce the operational friction and scale DNA engineering, we report here an in vivo DNA assembly technology platform called SCRIVENER (Sequential Conjugation and Recombination for In Vivo Elongation of Nucleotides with low ERrors). SCRIVENER combines

A Note on Tangential Quadrilaterals

September 2, 2024
Author(s)
Pradeep Das, Abhishek Juyal, Dustin Moody
A tangential quadrilateral is a convex quadrilateral whose sides are simultaneously tangent to a single circle. In this paper, the primary objective is to construct rational tangen- tial quadrilaterals characterized by having rational area, as well as

Advanced Co-simulation Framework for Assessing the Interplay between Occupant Behaviors and Demand Flexibility in Commercial Buildings

Zhelun Chen, Jin Wen, Yicheng Li, L James Lo, Gabriel Grajewski, Vance (Wm.) Payne, Steven T. Bushby, Amanda Pertzborn, Zheng O'Neill, Zhiyao Yang, Caleb Calfa
With buildings contributing significantly to electricity usage, enabling demand flexibility becomes a challenge, especially when accounting for occupant comfort. This study introduces an advanced co-simulation framework that integrated a range of models

An Overarching Quality Evaluation Framework for Additive Manufacturing Digital Twin

September 2, 2024
Author(s)
Yan Lu, Zhuo Yang, Shengyen Li, Yaoyao Fiona Zhao, Jiarui Xie, Mutahar Safdar, Hyunwoong Ko
The key differentiation of digital twins from existing models-based engineering approaches lies in the continuous synchronization between physical and virtual twins through data exchange. The success of digital twins, whether operated automatically or with

Data Science Education in Undergraduate Physics: Lessons Learned from a Community of Practice
