A Feature-preserved Canonical Form for Non-rigid 3D Meshes

April 14, 2011
Author(s)
Zhouhui Lian, Afzal A. Godil
Measuring the dissimilarity between non-rigid objects is a challenging problem in 3D shape retrieval. One potential solution is to construct the models’ 3D canonical forms (i.e., isometry-invariant representations in 3D Euclidean space) on which any rigid

Load Combination Requirements in ASCE Standard 7-10: New Developments

April 14, 2011
Author(s)
Therese P. McAllister, Bruce Ellingwood
The fundamental load combination requirements for strength design (or load and resistance factor design) appearing in Section 2.3 of ASCE Standard 7-10 advance those first developed and implemented in 1982, which since have achieved a state of maturity and

Reference Modulation for Calibrated Measurements of Tag Backscatter

April 14, 2011
Author(s)
Daniel G. Kuester, David R. Novotny, Jeffrey R. Guerrieri, Randy Direen, Zoya Popovic
We present a model and reference backscatter device for calibrating measurements of 860-960 MHz Ultra-High Fre- quency (UHF) tag backscattering. The model relates transmission to and backscattering from the device with a modulation depth calculable from

SHREC11 Track: Generic Shape Retrieval

April 14, 2011
Author(s)
Helin Dutagaci, Afzal A. Godil
In this paper we present the results of the 3D Shape Retrieval Contest 2011 (SHREC’11) track on generic shape retrieval. The aim of this track is to evaluate the performance of 3D shape retrieval algorithms that can operate on arbitrary 3D models. The

A new interface defect spectroscopy method

Jason T. Ryan, Liangchun (. Yu, Jae Han, Joseph J. Kopanski, Kin P. Cheung, Jason P. Campbell, Fei Zhang, Chen Wang, John S. Suehle, Vinny Tilak, Jody Fronheiser

A Route to Quantum Magnetism

April 13, 2011
Author(s)
Ian B. Spielman
The trend in using ultracold atoms as simulators of condensed-matter and many-body phenomena is gaining momentum. These systems can now be used to simulate quantum magnetism.

Differences in Polydimethylsiloxane Modification Methods Affect Laminin Deposition and Smooth Muscle Cell Proliferation

April 13, 2011
Author(s)
Joy P. Dunkers, Hae-Jeong Lee, Marvi Matos, Lisa Pakstis, Juan M. Taboas, Steven D. Hudson, Marcus T. Cicerone
When culturing cells on flexible surfaces, it is important to consider extracellular matrix treatments that will remain on the surface under mechanical strain. Here we investigate differences in laminin surfaces that were deposited on oxidized PDMS (plasma

Estimating Common Parameters in Heterogeneous Random Effects Models

April 13, 2011
Author(s)
Andrew L. Rukhin
A question of fundamental importance for meta-analysis of heterogeneous data studies is how to form a best consensus estimator of common parameters, and what uncertainty to attach to the estimate. This issue is addressed for a class of unbalanced linear

MODELING OF U.S. CORN ETHANOL INDUSTRIAL GROWTH

April 13, 2011
Author(s)
Deogratias Kibira, Guodong Shao, Stephen Nowak
The production capacity of corn ethanol as a transportation fuel is experiencing rapid growth in the United States. The demand is driven by increased prices of gasoline, government mandates, incentives, desire for cleaner fuels, and the need to achieve

Nonlinear Dynamic Analysis of Structures Using Modal Superposition

April 13, 2011
Author(s)
Kevin K. Wong
A fast nonlinear dynamic analysis algorithm based on modal superposition of structural response incorporating both material and geometric nonlinearities is proposed. Because linear modal superposition has found great acceptances in performance-based

A New Interface Defect Spectroscopy Method

Author(s)
Jason T. Ryan, Liangchun (. Yu, Jae Han, Joseph J. Kopanski, Kin P. Cheung, Fei Zhang, C Wang, Jason P. Campbell, John S. Suehle, Vinayak Tilak, Jody Fronheiser
A new interface defect spectroscopy method based on variable height charge pumping capable of observing the amphoteric nature of Si/SiO2 interface states in production quality sub-micron devices is demonstrated. It can help to resolve the long standing

Agile Test Framework for Business-to-Business Interoperability

April 12, 2011
Author(s)
Jungyub Woo, Nenad Ivezic, H Cho
Business-to-business (B2B) applications are tested routinely for conformance and interoperability against a set of data exchange standards before deployment. However, the existence of many data exchange standards, planned utilizations, deployment

Fast Neutron Detection with Li-6-loaded Liquid Scintillator

April 12, 2011
Author(s)
David M. Gilliam, B Fisher, J N. Abdurashitov, Kevin Coakley, V N. Gavrin, Jeffrey S. Nico, A A. Shikhin, Alan Keith Thompson, Dominic F. Vecchia, V E. Yants
We report on the development of a fast neutron detector using a liquid scintillator doped with enriched 6Li. The lithium was introduced in the form of an aqueous LiCl micro-emulsion with a di-isopropylnaphthalene based liquid scintillator. A 6Li

Interfacial effects on droplet dynamics in Poiseuille flow

April 12, 2011
Author(s)
Jonathan T. Schwalbe, Frederick R. Phelan Jr., Petia Vlahovska, Steven D. Hudson
Interfacial rheology governs many properties of emulsions, and here we report theory that accounts for and measure surface viscous and elastic forces. Stokes flow is assumed in bulk phases and a jump in hydrodynamic stress at the interface is balanced by

Lithography, Metrology and Nanomanufacturing

April 12, 2011
Author(s)
James A. Liddle, Gregg M. Gallatin
Semiconductor chip manufacturing is by far the predominant nanomanufacturing technology in the world today. Top-down lithography techniques are used for fabrication of logic and memory chips since, in order to function, these chips must essentially be

Microfabricated Chip Traps for Ions

April 12, 2011
Author(s)
Jason Amini, Joseph W. Britton, Dietrich G. Leibfried, David J. Wineland
This publication is a review of microfabricated ion traps for a book. We cover the basics of Paul traps, various geometries for realizing the traps, a number of design considerations, and, finally, a review of existing microfabricated traps.

Reference Modulation for Calibrated Measurements of Tag Backscatter
