Assessing Security and Privacy Controls in Information Systems and Organizations
This publication provides a set of procedures for conducting assessments of security and privacy controls employed within systems and organizations. The assessment procedures, executed at various phases of the system development life cycle, are consistent
Personal Identity Verification (PIV) of Federal Employees and Contractors
FIPS 201 establishes a standard for a Personal Identity Verification (PIV) system (Standard) that meets the control and security objectives of Homeland Security Presidential Directive-12 (HSPD-12). It is based on secure and reliable forms of identity
Reverberation Chamber Metrology for Wireless Internet of Things Devices: Flexibility in Form Factor, Rigor in Test
Internet of things (IoT) devices are proliferating in our connected world, with the number of devices expected to exceed 14 billion in 2023 [1] . Wireless IoT applications are increasing day by day, ranging from cellular-enabled parking meters that can
Development and Evaluation of Bluetooth Low-Energy Device for Electronic Encounter Metrics
The coronavirus disease 2019 (COVID-19) pandemic led to the need for tracking of physical contacts and potential exposure to disease. Traditional contact tracing can be augmented by electronic tools called "electronic contact tracing" or "exposure
Advantage of Machine Learning over Maximum Likelihood in Limited-Angle Low-Photon X-Ray Tomography
Limited-angle X-ray tomography reconstruction is an ill-posed inverse problem in general. Especially when the projection angles are limited and the measurements are taken in a photon-limited condition, reconstructions from classical algorithms such as
Bluetooth wireless technology is an open standard for short-range radio frequency communication used primarily to establish wireless personal area networks (WPANs), and has been integrated into many types of business and consumer devices. This publication
The National Institute of Standards and Technology (NIST) Communication Technology Laboratory (CTL) developed the Synthetic Aperture Measurement with Uncertainties and Angle of Arrival (SAMURAI) millimeter-wave testbed and technique. SAMURAI utilizes a
A Convolutional Neural Networks-Based Approach for Texture Directionality Detection
The perceived texture directionality is an important, not fully explored image characteristic. In many applications texture directionality detection is of fundamental importance. Several approaches have been proposed, such as the fast Fourier-based method
Optical Fiber Time Delay Comparison between NIST and LAMETRO
We describe the results of a bilateral measurement comparison of optical fiber time delay between the National Institute of Standards and Technology (NIST, USA) and Laboratorio de Metrología, Instituto Costarricense de Electricidad (LAMETRO-ICE, Costa Rica
Head Rotation Model for VR System Level Simulations

Identifying Tactics of Advanced Persistent Threats with Limited Attack Traces
The cyberworld being threatened by continuous imposters needs the development of intelligent methods for identifying threats while keeping in mind all the constraints that can be encountered. Advanced persistent threats (APT) have become an emerging issue
On Convergence of the Upper Bound on the Ratio of Gain to Quality Factor
An antenna's practical far-field distance can be estimated from the upper bound on the ratio of its gain to quality factor. This upper bound is an infinite series that can be truncated based on the desired far-field accuracy. We investigate the convergence
Atomistic Line Graph Neural Network for Improved Materials Property Predictions
Graph neural networks (GNN) have been shown to provide substantial performance improvements for atomistic material representation and modeling compared with descriptor-based machine learning models. While most existing GNN models for atomistic predictions
