HVAC CAD Layout Tools: A Case Study of University/Industry Collaboration

August 1, 1996
Author(s)
J Cagan, R Clark, P Dastidar, Simon Szykman, P Weisser
An effective partnership between industry and the university resulted in the system of design tools for the layout of HVAC systems presented in this paper and illustrated with the design of a heat pump. The system provides tools to assist in the placement

Measured Impact of a Rooftop Photovoltaic System

August 1, 2003
Author(s)
Arthur H. Fanney, E R. Weise, K R. Henderson
A 35-kilowatt roof top photovoltaic system has been installed at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland. The system, located on a the roof that connects NIST s Administration Building to its adjoining conference

STEP-NC COMPLIANT DATA REPRESENTATIONS FOR POWDER BED FUSION IN ADDITIVE MANUFACTURING

November 11, 2022
Author(s)
Fahad Milaat, Paul Witherell, Martin Hardwick, Ho Yeung, Vincenzo Ferrero, Laetitia Monnier, Matthew Brown
Powder bed fusion (PBF) is an additive manufacturing (AM) technology that uses powerful beams to fuse powder material into layers of scanned patterns, thus producing parts with great geometric complexity. For PBF, process parameters, environmental control

Wireless Channel Characterization for UWB Communication in Capsule Endoscopy

August 30, 2023
Author(s)
Katjana Ladic, Kamran Sayrafian, Dina Simunic, Kamya Yazdandoost
Since its invention in the early 1990s the technology behind capsule endoscopy has been making rapid progress. The emergence of high-resolution miniature video cameras along with other microsensor technology have increased the data rate and power

Additive Manufacturing Data Integration and Recommended Practice

June 30, 2023
Author(s)
Yan Lu, Milica Perisic, Albert T. Jones
Additive manufacturing (AM) creates parts layer by layer directly from three-dimensional computer-aided design data. Building in layers allows the fabrication of complex geometric shapes as well as functionally graded materials. Despite the part-quality

Electrically Conductive 3D Metal-Organic Framework Featuring p-Acidic Hexaazatriphenylene Hexacarbonitrile Ligands with Anion-p Interaction and Efficient Charge-Transport Capabilities

September 8, 2020
Author(s)
Ashok Yadav, Dillip K. Panda, Shiyu Zhang, Wei Zhou, Sourav Saha
Owing to their unparalleled synthetic simplicity, structural tunability, and functional versatility, electrically conductive metal–organic frameworks (MOFs) have emerged as one of the most promising electronic materials of the 21 st century. With much of

Status Report on the Second Round of the NIST Post-Quantum Cryptography Standardization Process

July 22, 2020
Author(s)
Dustin Moody, Gorjan Alagic, Daniel C. Apon, David A. Cooper, Quynh H. Dang, John M. Kelsey, Yi-Kai Liu, Carl A. Miller, Rene C. Peralta, Ray A. Perlner, Angela Y. Robinson, Daniel C. Smith-Tone, Jacob Alperin-Sheriff
The National Institute of Standards and Technology is in the process of selecting one or more public-key cryptographic algorithms through a public, competition-like process. The new public-key cryptography standards will specify one or more additional

Effects of laser-energy density and build orientation on the defect structure, microstructure and tensile properties of Inconel 718 parts manufactured with laser powder bed fusion

June 30, 2020
Author(s)
Dillon Watring, Jake Benzing, Nik Hrabe, Ashley Spear
This study investigates the processing-structure-property relationships of Inconel 718 manufactured by laser powder bed fusion. Three di erent build conditions were selected for the Inconel 718 specimens: 0 build orientation and 38 J/mm3, 0 build

Approaches to Training Multi-Class Semantic Image Segmentation of Damage in Concrete

May 14, 2020
Author(s)
Peter Bajcsy, Steven B. Feldman, Michael P. Majurski, Kenneth A. Snyder, Mary C. Brady
This paper addresses the problem of creating a large quantity of high-quality training image segmentation masks from scanning electron microscopy (SEM) images of concrete samples that exhibit progressive amounts of degradation resulting from alkali-silica

Characterization of an Extensive Interface on Vitronectin for Binding to Plasminogen Activator Inhibitor-1: Adoption of Structure in an Intrinsically Disordered Region

December 24, 2019
Author(s)
Letitia O. Puster, Christopher B. Stanley, Vladmir N. Uversky, Joseph E. Curtis, Susan T. Krueger, Yuzhuo Chu, Cynthia B. Peterson
Small-angle neutron scattering (SANS) measurements were used to characterize vitronectin, a protein found in human plasma and tissues that functions in regulating cell adhesion and migration, as well as proteolytic cascades that affect blood coagulation

Where do we start? Guidance for technology implementation in maintenance management for manufacturing

July 23, 2019
Author(s)
Michael P. Brundage, Thurston B. Sexton, Melinda Hodkiewicz, Katherine C. Morris, Jorge Arinez, Farhad Ameri, Jun Ni, Guoxian Xiao
Recent efforts in Smart Manufacturing (SM) have proven quite effective at elucidating system behavior using sensing systems, communications and computational platforms, along with statistical methods to collect and analyze real-time performance data

Structural and Dynamical Order of a Disordered Protein: Molecular Insights into Conformational Switching of PAGE4 at the Systems Level

February 1, 2019
Author(s)
Xingcheng Ling, Prakash Kulkarni, Federico Bocci, Nicholas Schafer, Susmita Roy, Min-Yeh Tsai, Yanan He, Yihong Chen, Krithika Rajagopalan, Steven Mooney, Yu Zeng, Keith Weninger, Alexander Grishaev, Jose Onuchic, Herbert Levine, Peter Wolynes, Govindan Rangarajan, Vladimir Uversky, John Orban, Mohit Jolly
Folded proteins show a high degree of structural order and undergo (fairly constrained) collective motions related to their functions. On the other hand, intrinsically disordered proteins (IDPs), while lacking a well-defined three-dimensional structure, do
