Efficient and Robust Optimization for building energy simulation

June 15, 2016
Author(s)
Shokouh Pourarian, Jin Wen, Anthony J. Kearsley, Amanda Pertzborn
Efficiently, robustly and accurately solving large sets of structured, non-linear algebraic and differential equations is one of the most computationally expensive steps in the dynamic simulation of building energy systems. Here, the efficiency, robustness

Critical Observations for the Evaluation of Cement Hydration Models

April 22, 2011
Author(s)
Dale P. Bentz
The development of computer models for cement hydration and microstructure development that has accelerated in the past 25 years has created a need for a set of critical experimental observations that can be used in evaluating the model predictions. During

A Physics Based Approach to Modeling Grassland Fires

January 30, 2007
Author(s)
William E. Mell, M A. Jenkins, J Gould, P Cheney
Physics based coupled fire-atmosphere models are based on approximations to the governing equations of fluid dynamics, combustion, and the thermal degradation of solid fuel. They require significantly more computational resources than the most commonly

Thermal Modeling of Multiple-Line-Heat-Source Guarded Hot Plate Apparatus

October 1, 2002
Author(s)
William M. Healy, D R. Flynn
The National Institute of Standards and Technology is building an advanced-design guarded hot plate apparatus of advanced design to provide very accurate thermal transmission properties for specimens of thermal insulation 500 mm in diameter, with

Reinterpretation of the Spectra of Hydrated Co++: An ab initio Study

July 1, 1998
Author(s)
H S. Gilson, Morris Krauss
The absorption spectrum of aqueous Co++ is reinterpreted in light of ab initio calculations. MCSCF and MR-MP calculations yield the spectral states and their oscillator strengths, as well as the spin-orbit coupling between the quartet and doublet states of

Validation of Standards Interfaces for Machine Control

May 27, 1996
Author(s)
Frederick M. Proctor, John L. Michaloski, William P. Shackleford, Sandor S. Szabo
… from basing a controller on common operating systems and computing platforms, the main feature of an open architecture … interfaces on controllers with specific operating systems, computing platforms, and control components. …

Compartment Fire-Generated Environment and Smoke Filling.

January 1, 1995
Author(s)
Leonard Y. Cooper
The following generic problem must be solved if one is to be able to establish the fire safety of building designs: [*] Given: Initiation of a fire in a compartment or enclosed space, [*] Predict: The environment that developes at likely locations of

Automating Interactive Applications in the Network Environment

July 1, 1992
Author(s)
Don E. Libes
Many programs demand to be run interactively. Word processors are good examples, but may network applications (e.g., ftp, telnet) share the same fault. They cannot be run non- interactively. Expect is a software tool designed to control interactive

Concurrent Engineering Through Product Data Standards

May 1, 1991
Author(s)
Gary Carver, Howard Bloom
Concurrent engineering involves the integration of people, systems, and information into a responsive, efficient system. Integration of computerized systems allows additional benefits: automatic knowledge capture during the development and lifetime

Super-resolution Localization and Tracking in WiFi Sensing

July 29, 2024
Author(s)
Jian Wang, Jack Chuang, Nada Golmie
Integrated sensing and communication (ISAC) systems have been investigated by the research and standardization communities in the recent past. Accurate localizing the target and tracking the target's movement are critical for numerous smart Internet of

Mathematical Entities: Corpora and Benchmarks

May 20, 2024
Author(s)
Jacob Collard, Valeria de Paiva, Eswaran Subrahmanian
Mathematics is a highly specialized domain with its own unique set of challenges. Despite this, there has been relatively little research on natural language processing for mathematical texts, and there are few mathematical language resources aimed at NLP

Knowledge Management for Data Analytics in Additive Manufacturing

November 21, 2023
Author(s)
Yeun Park, Paul Witherell, Albert T. Jones, Hyunbo Cho
As a multi-staged digital manufacturing process, Additive manufacturing (AM) inherently benefits from data analytics (DA) decision-making opportunities. The abundance of data associated with the various observations and measurements taken throughout the

Improving Support-Minors rank attacks: applications to GeMSS and Rainbow

October 12, 2022
Author(s)
John Bayron Baena Giraldo, Pierre Briaud, Daniel Cabarcas Jaramillo, Ray Perlner, Daniel Smith-Tone, Javier Verbel
The Support-Minors (SM) method has opened new routes to attack multivariate schemes with rank properties that were previously impossible to exploit, as shown by the recent attacks of [9, 40] on the Round 3 NIST candidates GeMSS and Rainbow respectively. In

Blockchain-Based Decentralized Authentication for Information-Centric 5G Networks

August 26, 2022
Author(s)
Muhammad Hassan Raza Khan, Davide Pesavento, Lotfi Benmohamed
The 5G research community is increasingly leveraging the innovative features offered by Information Centric Networking (ICN). However, ICN's fundamental features, such as in-network caching, make access control enforcement more challenging in an ICN-based

A NEIGHBORHOOD-BASED NEURAL NETWORK FOR MELT POOL PREDICTION AND CONTROL

September 1, 2020
Author(s)
Paul Witherell, Vadim Shapiro, Yaqi Zhang
One of the most prevalent additive manufacturing processes, the powder bed fusion process, is driven by a moving heat source that melts metals to build a part. This moving heat source, and the subsequent formation and moving of a melt pool, plays an

Probability of Coexistence of LTE-LAA and WLAN Systems Based on Delay Constraints

July 29, 2018
Author(s)
Yao Ma, William Young, Eric W. Anderson, Jason Coder
To support efficient spectrum sharing and related standardization efforts in unlicensed spectrum, it is important to develop analytical tools to accurately quantify coexistence performance between long-term evolution license assisted access (LTE-LAA) and

Towards Annotations and Product Definitions for Additive Manufacturing

May 20, 2016
Author(s)
Paul W. Witherell, Gaurav Ameta, Jennifer Herron
As AM is viewed more and more as a production-capable technology, the costs of complexity have become increasingly apparent in the form of information requirements. With design flexibilities come the need to capture and communicate complex shapes. In
