Towards a Markerless 3D Pose Estimation Tool

April 28, 2023
Author(s)
Amaan Rahman, Mili Shah, Ya-Shian Li-Baboud, Ann Virts
Evaluation of exoskeleton performance benefts from standards to verify proper functionality and safety. Currently, there are limited evaluation methods for exoskeletons. Measurement methods to evaluate human-exoskeleton kinematics include optical tracking

Three Years of DLMF: Web, Math & Search

August 1, 2013
Author(s)
Bruce R. Miller
DLMF was released to the public in May 2010 and is now completing its 3rd year online. As a somewhat early adopter of large-scale MathML content online, and exposing a math-aware search engine to the public, the project encountered situations distinct from

Usability Testing of Ten-Print Fingerprint Capture

October 8, 2007
Author(s)
Brian C. Stanton, Mary F. Theofanos, Shahram Orandi, Ross J. Micheals, Nien F. Zhang
Despite the increased deployment of biometric technologies in United States government applications, not enough attention is being paid to the human factors that such technologies involve. The use of biometric applications will be unfamiliar to many users

CAD/CAPP Integration using Feature Ontology

January 1, 2005
Author(s)
C Dartigues, P Ghodous, Michael Gruninger, D Pallez, Ram D. Sriram
In a collaborative computer-supported engineering environment, the interoperation of various applications will need a representation that goes beyond the current geometry-based representation, which is inadequate for capturing semantic information. The

When to Fuse Two Biometrics?

June 13, 2006
Author(s)
Elham Tabassi, Patrick J. Grother, George W. Quinn
Biometric fusion, acquisition and combination of multiple pieces of evidence of identity, can achieve higher accuracy of biometric recognition than using a single biometric. However, fusion increases the cost or throughput of the system since it requires

Extended Huckel Tight-Binding Approach to Electronic Excitations

July 25, 2008
Author(s)
Luis C. Rincon, Anwar Hasmy-Aguilar, Carlos A. Gonzalez, Rafael Almeida
In this work we propose the application of a self-consistent Extended Huckel Tight Binding method in the computation of the absorption optical spectrum of molecules within the linear response time dependent Density Functional formalism. The Extended Huckel
