Adsorption of Two Gas Molecules at a Single Metal Site in a Metal-Organic Framework

July 7, 2016
Author(s)
Tomce Runcevski, Matthew T. Kapelewski, Rodolfo M. Torres-Gavosto, Jacob Daniel Tarver, Craig Brown, Jeffrey R. Long
One strategy to markedly increase the gas storage capacity of metal-organic frameworks, is to introduce coordinatively-unsaturated metal centers capable of binding multiple gas molecules. Herein, we provide an initial demonstration that a single mental

Dynamic Equations for a Two-Link Flexible Robot Arm

December 30, 1988
Author(s)
Jonathan W. Lee, B Wang
The dynamic equations for a two-link flexible robot arm have been derived rigorously. The arm is moving in the vertical plane. The payload is simulated by attaching additional masses to the arm at any specific locations. Although the governing equations of

Direct Lagrangian Forcing Methods Based on Moving Least Squares

May 15, 2020
Author(s)
Marcos Vanella, Elias Balaras
The application of computational fluid dynamics to complex engineering flow problems necessitates the adoption of numerical algorithms that are accurate, robust and efficient at the same time. These are usually conflicting requirements and there is still

Indoor Air Quality in Sustainable, Energy Efficient Buildings

August 15, 2010
Author(s)
Andrew K. Persily, Steven J. Emmerich
… sometimes viewed as incompatible, there are in fact many strategies than can achieve both ends. This paper discusses … in terms of the impacts of ventilation. A number of strategies that are currently being used or proposed to …

Truncating the Singular Value Decomposition for Ill-Posed Problems

July 1, 1998
Author(s)
Bert W. Rust
Discretizing the first-kind integral equations which model many physical measurement processes yields an ill-conditioned linear regression model. Least squares estimation usually gives a sum of squared residuals much smaller than the expected value and a

The Need for a Robust, Precise Time and Frequency Alternative to GNSS

November 1, 2012

Michael A. Lombardi, Mitch Narins, Per Enge, Ben Peterson, Sherman Lo, Yu-Hsuan Chen, Dennis Akos
… and Timing (APNT) program to research various alternative strategies. These strategies are necessary to ensure a safe, secure, and … frequency services to other user communities. Alternatives strategies to be explored include use of existing NAS …

Stochastic Regression Modeling of Chemical Spectra

August 14, 2014
Author(s)
Anthony J. Kearsley, William E. Wallace, Yutheeka Gadhyan
A stochastic regression method has been developed that decomposes chemical spectra into separate contributions from signal and from noise. The numerical results of regressing in this way on sample spectra are presented. The results suggest that this

Using and creating databases for data analysis in laser spectroscopy

January 1, 2014
Author(s)
Alexander Kramida
A brief review of existing atomic spectroscopy databases is given with an emphasis on databases relevant to laser spectroscopy research. Key data elements in these databases are described. A strategy of building a specialized relational database for laser

Use Case Based Testing Applied to Smart Grid Development

Author(s)
Eric D. Simmon, Arthur Griesser
The US Power delivery system is being updated by grafting an intelligent, decision making network to the existing grid. If designed correctly, this smart grid will ensure that the power grid can meet our needs in the coming century. This paper discusses a
