Facilitating Stakeholder Communication around AI-Enabled Systems and Business Processes

November 21, 2023
Author(s)
Edward Griffor, Matthew Bundas, Chasity Nadeau, Jeannine Shantz, Thanh Nguyen, Marcello Balduccini, Tran Son
Artificial Intelligence (AI) is often critical to the success of modern business processes. Leveraging it, however, is non-trivial. A major hurdle is communication: discussing system requirements among stakeholders with different backgrounds and goals

Wireless Channel Characterization for UWB Communication in Capsule Endoscopy

August 30, 2023
Author(s)
Katjana Ladic, Kamran Sayrafian, Dina Simunic, Kamya Yazdandoost
Since its invention in the early 1990s the technology behind capsule endoscopy has been making rapid progress. The emergence of high-resolution miniature video cameras along with other microsensor technology have increased the data rate and power

Smart Home Device Loss of Support: Consumer Perspectives and Preferences

July 23, 2023
Author(s)
Julie Haney, Susanne M. Furman
Unsupported smart home devices can pose serious safety and security issues for consumers. However, unpatched and vulnerable devices may remain connected because consumers may not be alerted that their devices are no longer supported or do not understand

2022 Cybersecurity & Privacy Annual Report

May 30, 2023
Author(s)
Patrick D. O'Reilly, Kristina Rigopoulos, Larry Feldman, Greg Witte
During Fiscal Year 2022 (FY 2022) – from October 1, 2021, through September 30, 2022 –the NIST Information Technology Laboratory (ITL) Cybersecurity and Privacy Program successfully responded to numerous challenges and opportunities in security and privacy

User Perceptions and Experiences with Smart Home Updates

May 22, 2023
Author(s)
Susanne M. Furman, Julie Haney
Updates may be one of the few tools consumers have to mitigate security and privacy vulnerabilities in smart home devices. However, little research has been undertaken to understand users' perceptions and experiences with smart home updates. To address

Reusable Network Simulation for CPS Co-Simulations

May 9, 2023
Author(s)
Himanshu Neema, Harmon Nine, Thomas Roth
Cyber-Physical Systems (CPS) require seamless integration of physical and computation components through communication networks. They often contain sub-systems from different physical domains (e.g., electrical, mechanical, and electronic) that must

Comparing Economic Benefits of HVAC Control Strategies in Grid-Interactive Residential Buildings

May 1, 2023
Author(s)
Brian Woo-Shem, Kaleb Pattawi, Hannah Covington, Patrick McCurdy, Chenli Wang, Thomas Roth, Cuong Nguyen, Yuhong Liu, Hohyun Lee
Energy consumption in buildings continues to rise with increased deployment of energy-consuming equipment such as Heating, Ventilation, and Air Conditioning (HVAC) amid a growing world economy. Renewable energy is projected to comprise a majority of the

On Predistortion Filtering for Switched Beamforming With Phased-Array Antennas

March 26, 2023
Author(s)
Jack Chuang, Camillo Gentile
In recent work, we proposed sweeping the antennas of phased arrays and beamforming in postprocessing – what we coined switched beamforming – instead of sweeping beams through analog beamforming – what the arrays are designed for. Not only is it orders of

IoT Capabilities Composition and Decomposition: A Systematic Review

March 22, 2023
Author(s)
Edward Griffor, Khalid Halba, ahmed lbath, Anton Dahbura
Internet of Things (IoT) capabilities are features or services produced by IoT devices. IoT capabilities composition brings existing capabilities together to create a novel service with added value. IoT Capabilities decomposition works the other way around

Scalable Modeling of Human Blockage at Millimeter-Wave: A Comprehensive Analysis of Knife-Edge Diffraction, the Uniform Theory of Diffraction, and Physical Optics Against 60 GHz Channel Measurements

December 22, 2022
Author(s)
Anmol Bhardwaj, Camillo Gentile, Jelena Senic
Human blockage at millimeter-wave frequencies is most commonly modeled through Knife-Edge Diffraction (KED) from the edges of a vertical strip. Although extensively validated through controlled laboratory experiments, the method does not scale to realistic
