Using Chebyshev Polynomials for Interpreting Structured Light Images

April 1, 1985
Author(s)
Michael O. Shneier, W Rutowski, Tsai H. Hong
A method is described of representing curved or line-like segments of images using Chebyshev polynomials. The advantages of the approximations include fast computation, minimum error over the sampling interval, and the reduction of the data to a concise

Hallucination Detection in Large Language Models Using Diversion Decoding

June 24, 2025
Author(s)
Basel Abdeen, S M Tahmid Siddiqui, Meah Tahmeed Ahmed, Anoop Singhal, Latifur Khan, Punya Modi, Ehab Al-Shaer
Large language models (LLMs) have emerged as a powerful tool for retrieving knowledge through seamless, human-like interactions. Despite their advanced text generation capabilities, LLMs exhibit hallucination tendencies, where they generate factually

A collaborative study on the precision of the Markov chain Monte Carlo algorithms used for DNA profile interpretation

June 19, 2024
Author(s)
Sarah Riman, Jo-Anne Bright, Kaitlin Huffman, Lilliana Moreno, Sicen Liu, Asmitha Sathya, Peter Vallone
Several fully continuous probabilistic genotyping software (PGS) use Markov chain Monte Carlo algorithms (MCMC) to assign weights to different proposed genotype combinations at a locus. Replicate interpretations of the same profile in these software are

AtomVision: A machine vision library for atomistic images

March 1, 2023
Author(s)
Brian DeCost, Ramya Gurunathan, Adam Biacchi, Kamal Choudhary
Computer vision techniques have immense potential for materials design applications. In this work, we introduce an integrated and general-purpose AtomVision library that can be used to generate and curate microscopy image (such as scanning tunneling

Evaluation of Nondestructive Volumetric Testing Methods for Additively Manufactured Parts

June 4, 2020
Author(s)
Anne Francoise H. Obaton, Bryan Butsch, Stephen McDonough, Nans Laroche, Yves Gaillard, Jared Tarr, Patrick Bouvet, Rodolfo Cruz, Alkan Donmez
Additive manufacturing enables the production of customized and complex parts. These two aspects are very attractive for aerospace and medical sectors. However, in these critical sectors, governed by strict safety requirements, the quality of the parts is

Simulation of TTT curves for additively manufactured Inconel 625

January 1, 2019
Author(s)
Carelyn E. Campbell, Greta Lindwall, Eric Lass, Fan Zhang, Mark R. Stoudt, Andrew J. Allen, Lyle E. Levine
The ability to use common computational thermodynamic and kinetic tools to study the microstructure evolution in Inconel 625 (IN625) manufactured using the additive manufacturing (AM) technique of laser powder-bed fusion is evaluated. Solidification

Time in Cyber-Physical Systems

October 2, 2016
Author(s)
Marc A. Weiss, Sundeep Chandhoke, Hugh Melvin
… distinguishing Cyber-Physical Systems from distributed computing in general. However mixing the cyber and the …

Mapping Evidence Graphs to Attack Graphs

January 17, 2013
Author(s)
Changwei Liu, Anoop Singhal, Duminda Wijesekera
Attack graphs compute potential attack paths from a system configuration and known vulnerabilities of a system. Evidence graphs model intrusion evidence and dependencies among them for forensic analysis. In this paper, we show how to map evidence graphs to

A Review of Building Evacuation Models, 2nd Edition

November 1, 2010
Author(s)
Erica D. Kuligowski, Richard D. Peacock, Bryan L. Hoskins
Evacuation calculations are increasingly becoming a part of performance-based analyses to assess the level of life safety provided in buildings. In some cases, engineers are using back-of-the-envelope (hand) calculations to assess life safety, and in

Measurement Uncertainties in Speaker Recognition Evaluation

September 15, 2010
Author(s)
Jin Chu Wu, Alvin F. Martin, Craig S. Greenberg, Raghu N. Kacker
The speaker recognition evaluation is an ongoing series of evaluations conducted by NIST. A detection cost function is computed over the sequence of trials provided and used for all speaker detection tests while measuring speaker detection performance. The
