Tunable zero-field magnetoresistance responses in Si transistors: Origins and applications

April 16, 2024
Author(s)
Stephen Moxim, Nicholas Harmon, Kenneth Myers, James P Ashton, Elias Frantz, Michael Flatte, Patrick Lenahan, Jason Ryan
The near-zero-field magnetoresistance (NZFMR) response has proven to be a useful tool for studying atomic-scale, paramagnetic defects that are relevant to the reliability of semiconductor devices. The measurement is simple to make and, in some cases

An Overarching Quality Evaluation Framework for Additive Manufacturing Digital Twin

April 15, 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

Evaluating Models That Predict Epoxy Conversion Using Rheological Properties

April 15, 2024
Author(s)
Stian Romberg, Paul Roberts, Chad R. Snyder, Anthony Kotula
Simultaneous rheology and conversion measurements of neat and composite epoxy resins reveal that conventional models neither accurately nor fully describe the relationship between rheology and conversion. We find that models predicting thermoset conversion

Author(s)

Amar Abane, Abdella Battou, Mheni Merzouki

This paper presents a network management AI assistant built with Large Language Models. It adapts at runtime to the network state and specific platform, leveraging techniques like prompt engineering, document retrieval, and Knowledge Graph integration. The

Building a Digital Twin of a CNC Machine Tool

April 12, 2024
Author(s)
Deogratias Kibira, Guodong Shao, Rishabh Venketesh, Matthew Triebe
Developing digital twins for manufacturing applications is challenging due to insufficient modeling frameworks and standardized procedures. As a result, the number of successful digital twin implementations has not caught up with the increasing literature

Comparison of Flow Measurement Devices for Large Fire Experiments

April 12, 2024
Author(s)
Giovanni Di Cristina Torres, Rodney Bryant
Bi-directional probes are utilized throughout fire research and testing to measure fire induced flows due to their ability to measure flow which changes direction, and to withstand hostile environments. However, they are not available commercially and

Integrating Dynamic Digital Twins: Enabling Real-Time Connectivity for IoT and Virtual Reality

Author(s)
Lejla Erdal, Ammar Gubartalla, Paulo Victor Lopes, Huizhong Cao, Guodong Shao, Per Lonnehed, Henri Putto, Abbe Ahmed, Sven Ekered, Bjorn Johansson
As Industry 4.0 technology is still evolving, research and implementation gaps due to issues such as costs, security, and lack of domain expertise for enabling Digital Twins and supportive technology need to be bridged. This paper proposes a practical

Dielectric Characterization of H2O and CO2 Uptake by Polyethylenimine Films

April 10, 2024
Author(s)
Jan Obrzut, Jennifer Clark, Avery Baumann, Jack F. Douglas
This study investigates the dielectric properties of branched polyethylenimine (PEI) films in relation to their interaction with moisture and CO2. The dielectric measurements were carried out using a non-contact resonant microwave cavity testing method
