Real-Time Flashover Prediction Model for Multi-Compartment Building Structures Using Attention Based Recurrent Neural Networks

March 17, 2023
Author(s)
Wai Cheong Tam, Eugene Yujun Fu, Jiajia Li, Richard D. Peacock, Paul A. Reneke, Thomas Cleary, Grace Ngai, Hong Va Leong, Michael Xuelin Huang
This paper presents the development of an attention based bi-directional gated recurrent unit model, P-Flashv2, for the prediction of potential occurrence of flashover in a traditional 111 m2 single story ranch-style family home. Synthetic temperature data

Controlling solute trapping and solute drag in a phase-field model

March 16, 2023
Author(s)
Arnab Mukherjee, James A. Warren
The finite solid-liquid interface width in phase-field models results in non-equilibrium effects, including solute trapping. Prior phase field modeling has shown that this extra degree of freedom, when compared to sharp-interface models, results in solute

Synergistic Fire Resistance of Nanobrick-wall Coated 3D Printed Photopolymer Lattices

March 16, 2023
Author(s)
Thomas Kolibaba, Callie Higgins, Zack Buck, Dash Weeks, Jason Killgore
Photopolymer additive manufacturing has become the subject of widespread interest in recent years due to its capacity to enable fabrication of difficult geometries that are impossible to build with traditional modes of manufacturing. The flammability of

Users Are Not Stupid: Six Cyber Security Pitfalls Overturned

March 16, 2023
Author(s)
Julie Haney
The skilled and dedicated professionals who strive to improve cyber security may unwittingly fall victim to misconceptions and pitfalls that hold customers and users back from reaching their full potential of being active partners in security. These

Beating thermal noise in a dynamic signal measurement by a nanofabricated cavity-optomechanical sensor

March 15, 2023
Author(s)
Mingkang Wang, Diego Perez Morelo, Georg Ramer, Georges Pavlidis, Jeffrey Schwartz, Liya Yu, Robert Ilic, Andrea Centrone, Vladimir Aksyuk
Thermal fluctuations often impose both fundamental and practical measurement limits on high-performance sensors, motivating the development of techniques that bypass the limitations imposed by thermal noise outside cryogenic environments. Here, we

Modelling Study of Interactions of Ozone and Hydrogen Peroxide on Indoor Surfaces

March 15, 2023
Author(s)
Dustin Poppendieck, Toby J. Carter, David Shaw, Nicola Carslaw
In recent decades, the role of the indoor microenvironment in our exposure to air pollutants has become clearer. Indoor air pollutants are emitted from common household items, including building materials and furnishings, and can then undergo chemical

Polyethyleneimine/polyethylene glycol-conjugated gold nanoparticles as nanoscale positive/negative controls in nanotoxicology: Testing in frog embryo teratogenesis assay-Xenopus and mammalian tissue culture system

March 15, 2023
Author(s)
Vytas Reipa, Alessandro Tona, Feng Yi, Bryant C. Nelson, David A. LaVan, Vincent A. Hackley, Tae Joon Cho
Despite the great potential of using positively charged gold nanoparticles (AuNPs) in nanomedicine, no systematic studies have been reported on their synthesis optimization or colloidal stability under physiological conditions until a group at the National

Two-beam nonlinearity in indium tin oxide in the continuous wave limit

March 15, 2023
Author(s)
Jared Wahlstrand, Chad Cruz
Indium tin oxide (ITO) is an example of a material with a greatly enhanced optical nonlinearity for wavelengths at which the dielectric permittivity is near zero. Its enormous nonlinearity may enable compact photonic devices. All-optical devices involve

A Goldilocks Approach to Water Management: Amphiphilic Porous Transport Layers for Unitized Reversible Fuel Cells

March 14, 2023
Author(s)
Siddharth Komini Babu, Abdurrahman Yilmaz, Md Aman Uddin, Jacob LaManna, Elias Baltic, David Jacobson, Ugur Pasaogullari, Jacob Spendelow
Unitized reversible fuel cells (URFCs) are a promising option for both local and grid-scale energy storage, and could help facilitate the deployment of intermittent renewable power sources. URFCs consist of a single cell that operates in both fuel cell (FC

A Review of Machine Learning Control in Building Operations

March 14, 2023
Author(s)
Liang Zhang, Zhelun Chen, Xiangyu Zhang, Amanda Pertzborn
Machine learning control (MLC) is a highly flexible and adaptable method that enables the design, modeling, tuning, and maintenance of building controllers to be more accurate, automated, flexible, and adaptable. The research topic of MLC in building
