Gap Analysis for Key Interoperability Scenarios in Election Technology

August 1, 2022
Author(s)
John Dziurlaj, Benjamin Long
This document describes potential use-cases for data interoperability in election technology components not previously considered in past efforts. Such components include on-demand ballot printing systems, remote ballot marking systems and electronic poll

Recommendations for Voting System Interoperability

August 1, 2022
Author(s)
John Dziurlaj, Benjamin Long
There is currently no common data format for ballot styles and associated use-cases. This white paper investigates this and other potential interoperability gaps within the voting system in a holistic manner, by considering previous voting interoperability

Knowledge Mining in Cybersecurity: From Attack to Defense

July 18, 2022
Author(s)
Khandakar Ashrafi Akbar, Sadaf MD Halim, Yibo Hu, Anoop Singhal, Latifur Khan, Bhavani Thuraisingham
In the fast-evolving world of Cybersecurity, an analyst often has the difficult task of responding to new threats and attack campaigns within a limited amount of time. If an analyst fails to do so, this can lead to severe consequences for the system under

What Makes a Good Podcast Summary?

July 11, 2022
Author(s)
Rezvaneh Rezapour, Sravana Reddy, Rosie Jones, Ian Soboroff
Abstractive summarization of podcasts is motivated by the growing popularity of podcasts and the needs of their listeners. Podcasting is a markedly different domain from news and other media that are commonly studied in the context of automatic

Measurement Challenges for Scaling Superconductor-based Quantum Computers

June 23, 2022
Author(s)
Pete Hopkins, Manuel Castellanos Beltran, John Biesecker, Paul Dresselhaus, Anna Fox, Logan Howe, David Olaya, Adam Sirois, Dylan Williams, Samuel P. Benz, Alirio De Jesus Soares Boaventura, Justus Brevik
Global investment in the research and development of quantum information systems by industry, government, and academic institutions continues to accelerate and is expected to reach over $16B by 2027 [1]. Systems based on optical photons, atoms or ions

Heterogenous Domain Adaptation for Multi stream Classification on Cyber Threat Data

June 13, 2022
Author(s)
Yi Fan Li, Yang Gao, G Ayoade, L Khan, Anoop Singhal, B Thuraisingham
Under a newly introduced setting of multi stream classification, two data streams are involved, which are referred to as source and target streams. The source stream continuously generates data instances from a certain domain with labels, while the target

Ordered t-way Combinations for Testing State-based Systems

June 13, 2022
Author(s)
D. Richard Kuhn, M S Raunak, Raghu N. Kacker
Fault detection often depends on the specific order of inputs that establish states which eventually lead to a failure. However, beyond basic structural coverage metrics, it is often difficult to determine if code has been exercised sufficiently to ensure

Physics-assisted Generative Adversarial Network for X-Ray Tomography

June 10, 2022
Author(s)
Zhen Guo, Jungki Song, George Barbastathis, Michael Glinsky, Courtenay Vaughan, Kurt Larson, Bradley Alpert, Zachary H. Levine
X-ray tomography is capable of imaging the interior of objects in three dimensions non-invasively, with applications in biomedical imaging, materials study, electronic inspection, and other fields. The reconstruction process can be an ill-conditioned

Developing multithreaded techniques and improved constraint handling for the tool CAgen

June 8, 2022
Author(s)
Michael Wagner, Manuel Leithner, Dimitris Simos, D. Richard Kuhn, Raghu N. Kacker
CAgen is a state-of-the-art combinatorial test generation tool that is known for its execution speed. In addition, it supports an extensive list of features such as constraint handling, higher-index arrays, and import and export of models/test sets in

Measurement-induced quantum phases realized in a trapped-ion quantum computer

June 2, 2022
Author(s)
Michael Gullans, Alexey Gorshkov, David Huse, Christopher Monroe, Crystal Noel, Pradeep Niroula, Daiwei Zhu, Andrew Risinger, Laird Egan, Debopriyo Biswas, Marko Cetina
Many-body open quantum systems balance internal dynamics against decoherence from interactions with an environment. Here, we explore this balance via random quantum circuits implemented on a trapped-ion quantum computer, where the system evolution is

Blockchain for Access Control Systems

May 26, 2022
Author(s)
Vincent C. Hu
The rapid development and wide application of distributed network systems have made network security – especially access control and data privacy – ever more important. Blockchain technology offers features such as decentralization, high confidence, and
