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

On Effectiveness of Smart Grid Applications using Co-simulation

August 6, 2015
Author(s)
Paul Moulema, Wei Yu, David W. Griffith, Nada T. Golmie
The smart grid is a complex system that comprises components from both the power grid and communication networks. To understand the behavior of such a complex system, co-simulation is a viable tool to capture the interaction and the reciprocal effects

Toward a Formal Common Information Model Ontology

November 1, 2004
Author(s)
Stephen Quirolgico, P Assis, A Westerinen, M Baskey, E Stokes
We examine the performance of multimodal biometric authentication systems using state-of-the-art Commercial Off-the-Shelf (COTS) fingerprint and face biometric systems on a population approaching 1,000 individuals. Majority of prior studies of multimodal

Towards Modeling the Evolution of Product Families

June 1, 2003
Author(s)
Fujun Wang, Steven J. Fenves, Sudarsan Rachuri, Ram D. Sriram
A strategy successfully used by manufacturing companies is to develop product families so as to offer a variety of products with reduced development costs. This paper introduces our initial research on the representation of the evolution of product

What are Feature Interactions?

September 1, 1996
Author(s)
William Regli, Mike Pratt
Manufacturing features and their interactions have become areas of research scrutiny in recent years. It is widely accepted that intelligent reasoning about interactions among features is a critical element in the development of systems for automated

X-Ray Diffraciton and the Existence of Long Range Internal Stresses

October 12, 2021
Author(s)
M A. Delos-Reyes, M E. Kassner, Lyle E. Levine
Long range internal stresses (LRIS) are often used to explain various aspects of the mechanical behavior of materials. Recent experiments by the authors indicate an absence of measurable LRIS. X-ray line asymmetry, however, has long been interpreted as an

Rafting and Elastoplastic Deformation of Superalloys Studied by Neutron Di raction

June 1, 2017
Author(s)
James Coakley, Eric Lass, Dong Ma, Matthew Frost, David N. Seidman, David C. Dunand, Howard Stone
The rafting of monocrystalline Ni- and Co-based superalloys has been studied by neutron diffractometry. The nature of rafting is shown experimentally to be dependent upon both the lattice parameter misfit and the difference in phase stiffnesses. The 900 ◦C

Building Caring Healthcare Systems in the Internet of Things

February 22, 2017
Author(s)
Phillip Laplante, Mohamad Kassab, Nancy Laplante, Jeff Voas
The nature of healthcare and the computational and physical technologies and constraints present a number of challenges to systems designers and implementers. In spite of the challenges, there is a significant market for systems and products to support

An Exception to Amontons' Law: The Friction of Carbon Surfaces in Air

February 19, 2017
Author(s)
P M. McGuiggan
The friction of carbon has been of much interest in recent years due to its good tribological properties. These properties include high wear resistance, high hardness, low friction coefficients, and low corrosion. 1 In computer hard disks, the magnetic

2015 TMS William Hume-Rothery Award and Symposium

February 22, 2016
Author(s)
Ursula R. Kattner
The symposium was titled “Multicomponent Alloy Metallurgy: Bridge from Materials Science to Materials Engineering” with focus on the physical metallurgy of alloys with three or more components. The topics of interest for the symposium included

Vetting Mobile Apps

July 22, 2011
Author(s)
Stephen Quirolgico, Jeffrey M. Voas, David R. Kuhn
Billions of copies of apps for mobile devices have been purchased in recent years. With this growth, however, comes an increase in the spread of potentially dangerous security vulnerabilities. Because of an app's low cost and high proliferation, the threat

Correction of Location and Orientation Errors in Electromagnetic Motion Tracking

August 1, 2007
Author(s)
John G. Hagedorn, Steven G. Satterfield, John T. Kelso, W. Austin, Judith E. Terrill, Adele Peskin
We describe a method for calibrating an electromagnetic motion tracking device. Algorithms for correcting both location and orientation are presented. In particular, we use a method for interpolating rotation corrections at scattered data points that has
