Comparison of Three Methods for Oscillating Flow Measurements in Cryocoolers

October 16, 2024
Author(s)
Ryan Snodgrass, Vincent Kotsubo, Joel Ullom
Measurement of oscillating mass flows is typically required for the study of cryocoolers and cryocooler compressors. Although many measurement techniques are used in the cryocooler literature, detailed comparisons are lacking, so it can be challenging for

Development of a Forensic DNA Research Grade Test Material

Author(s)
Nicolau Lopez-Pinto, Christopher Jensen, Zhijie Chen, Zhengwei Tan, Zheng Ma, Maciej Liedke, Maik Butterling, Andreas Wagner, Javier Herrero-Martin, Enric Menendez, Josep Nogues, Kai Liu, Jordi Sort
The increasing energy demand in information technologies requires novel low-power procedures to store and process data. Magnetic materials, central to these technologies, are usually controlled through magnetic fields or spin-polarized currents that are

BIT-FL: Blockchain-Enabled Incentivized And Secure Federated Learning Framework

October 14, 2024
Author(s)
Tao Zhang, Chenhao Ying, Fuyuan Xia, Haiming Jin, Yuan Luo, David Wei, Xinchun Yu, Yibin Xu, Xikun Jiang, Weiting Zhang, Dacheng Tao
Federated learning (FL) enables the protection of data privacy through collaborative training of a machine learning (ML) model without sharing local data. However, several common problems arise when designing FL frameworks, as they rely on a central server

A Guide to the Smart Investment Tools

October 10, 2024
Author(s)
Douglas Thomas, Joshua D. Kneifel, Purav Parekh
This report serves as a guide to the Smart Investment Tool and Smart Investment Tool Express (SITExpress). These tools aid a user in conducting an investment analysis with a focus on those in the manufacturing industry; however, the methods can be used for
