Dictionary Learning from Ambiguously Labeled Data

April 9, 2013
Author(s)
P J. Phillips, Yi-Chen Chen, Vishal M. Patel, Jaishanker K. Pillai, Rama Chellappa
We propose a novel dictionary-based learning method for ambiguously labeled multiclass classification, where each training sample has multiple labels and only one of them is the correct label. The dictionary learning problem is solved using an iterative

Towards Evolutionary-Pricing Framework for Mobile Sensor Network Self-organization

July 18, 2010
Author(s)
Vladimir V. Marbukh, Kamran Sayrafian, Hamid Mahboubi, Ahmadreza Momeni, Amir G. Aghdam
This paper reports on work in progress on developing a unified co-evolutionary/pricing framework for Mobile Sensor Networks (MSN) self-organization. MSN self-organization involves cooperative sensor positioning and formation of a multi-hop Mobile Ad-hoc

Quantifying How Lighting and Focus Affect Face Recognition Performance

June 13, 2010
Author(s)
J. R. Beveridge, David Bolme, Bruce A. Draper, Geof H. Givens, Yui M. Lui, P. Jonathon Phillips
Recent studies show that face recognition in uncontrolled images remains a challenging problem, although the reasons why are less clear. Changes in illumination are one possible explanation, although algorithms developed since the advent of the PIE and

Lower Bounds for Accessing Information on Pure Pointer Machines

July 13, 2009
Author(s)
Brian D. Cloteaux, Desh Ranjan
We study the complexity of representing an array on a Pure Pointer Machine (PPM) or a pointer machine without arithmetic capabilities. In particular, we show that lower bounds in access time for information retrieval on a PPM arise from two different

Towards Standards for Integrated Gaming and Simulation for Incident Management

July 1, 2007
Author(s)
Sanjay Jain, Charles R. McLean, Yung-Tsun T. Lee
Simulation and gaming can support decision making through all phases of incident management including prevention, preparedness, response, recovery and mitigation. A number of gaming and simulation tools have been developed for the purpose but they

A Simulation Architecture for Manufacturing Interoperability Testing

May 1, 2007
Author(s)
Charles R. McLean, Sanjay Jain, Frank H. Riddick, Yung-Tsun T. Lee
Manufacturing systems are often costly to develop and operate. Simulation technology has been demonstrated to be an effective tool for improving the efficiency of manufacturing system design, operation, and maintenance. But manufacturing simulations are

Discovery in Hydrating Plaster Using Multiple Machine Learning Methods

August 3, 2003
Author(s)
John G. Hagedorn, J E. Devaney
We apply multiple machine learning methods to obtain concise rules that are highly predictive of scienti cally meaningful classes in hydrating plaster over multiple time periods. We use three dimensional data obtained through X-ray microtomography at

The IMS MISSION Architecture for Distributed Manufacturing Simulation

June 1, 2001
Author(s)
Charles R. McLean, Frank H. Riddick
This paper presents an overview of a neutral reference architecture for integrating distributed manufacturing simulation systems with each other, with other manufacturing software applications, and with manufacturing data repositories. Other manufacturing

Automated Parameter Extraction Software for Advanced IGBT Modeling

July 10, 2000
Author(s)
Allen R. Hefner Jr., Sebastien Bouche
A software package for extracting parameters used in advanced IGBT models is presented. In addition, new model equations and extraction procedures are introduced that more accurately describe a wide range of IGBT types including the recently developed Warp

Feature Recognition for Manufacturability Analysis

January 1, 1994
Author(s)
William Regli, Satyandra K. Gupta, D Nau
While automated recognition of features has been attempted for a wide range of applications, no single existing approach possesses the functionality required to perform manufacturability analysis. In this paper, we present a methodology for taking a CAD

Production Control Module for the AMRF

November 1, 1985
Author(s)
Albert T. Jones, Charles R. McLean
The Automated Manufacturing Research Facility (AMRF) is being established at the National Bureau of Standards. This manufacturing testbed provides a means for conducting research in automated metrology and interface standards for the factory of the future

The role of molecular modeling & simulation in the discovery and deployment of metal-organic frameworks for gas storage and separation

August 8, 2019
Author(s)
Arni Sturluson, Melanie Huynh, Alec Kaija, Caleb Laird, Sunghyun Yoon, Feier Hou, Zhenxing Feng, Christopher E. Wilmer, Yamil J. Colon, Yongchul G. Chung, Daniel Siderius, Cory M. Simon
Metal-organic frameworks (MOFs) are highly tunable, extended-network, crystalline, nanoporous materials with applications in gas storage, separations, and sensing. We review how molecular models and simulations of gas adsorption in MOFs have lucidly

A Low-Cost Time Transfer Receiver for Contributions to Coordinated Universal Time

November 6, 2014
Author(s)
Michael A. Lombardi, Andrew N. Novick, Victor S. Zhang
This paper describes a low-cost time transfer receiver that allows timing laboratories, including national metrology institutes and other designated institutions, to contribute data to the computation of Coordinated Universal Time (UTC). The time transfer

Investigating the Application of Moving Target Defenses to Network Security

August 15, 2013
Author(s)
Rui Zhuang, Su Zhang, Alex Bardas, Scott DeLoach, Xinming Ou, Anoop Singhal
This paper presents a preliminary design for a moving-target defense (MTD) for computer networks to combat an attacker's asymmetric advantage. The MTD system reasons over a set of abstract models that capture the network's configuration and its operational

A new algorithm for clock weights for the SIM time scale

May 24, 2012
Author(s)
Michael A. Lombardi, J. Mauricio Lopez-Romero, Nelida Diaz-Munoz, E. de Carlos-Lopez
A time and frequency comparison system has been developed for the Sistema Interamericano de Metrologia (SIM) region in order to compare in real time the time references maintained at the SIM national metrology institutes (NMIs). Since January 2010 a

Numerical Modeling of Diffusion-Induced Deformation

September 11, 2006
Author(s)
J A. Dantzig, William J. Boettinger, James A. Warren, Geoffrey B. McFadden, Sam R. Coriell, R F. Sekerka
We present a numerical approach to modeling the deformation induced the the Kirkendall effect in binary alloys. The governing equations for isothermal binary diffusion are formulated with respect to inert markers and also with respect to the volume
