A Framework to Evaluate the Cost-Effectiveness of Recovery-Based Design

May 24, 2022
Juan Fung, Yating Zhang, Katherine Johnson, Dustin Cook, Siamak Sattar
Modern building codes and standards are generally focused on safeguarding public health and safety by ensuring buildings meet life safety performance objectives following an earthquake event. Certain classes of buildings, such as hospitals and schools, may

Pairs of Heron and right triangles with a common area and a common perimeter

May 23, 2022
Abhishek Juyal, Dustin Moody
A Heron triangle is one in which the side lengths and area are integers. An integral right triangle is an example of a Heron triangle. In this paper, we show that there are infinitely many pairs of integral right triangles and Heron triangles with a common

A Data Structure for Integrity Protection with Erasure Capability

May 20, 2022
D. Richard Kuhn
This document describes a data structure, referred to as a data block matrix, that supports the ongoing addition of hash-linked records while also allowing for the deletion of arbitrary records, thereby preserving hash-based integrity assurance that other

NIST Cybersecurity Role-based Training Study Presentation

May 20, 2022
Jody Jacobs, Julie Haney, Susanne M. Furman
This presentation is for the May 17, 2022 Federal Information Security Educators (FISSEA) Spring Forum hosted by NIST. This presentation will present our preliminary findings from our Role-Based Training Study.

Value of information and decision pathways: Concepts and case studies

May 20, 2022
Pierre Glynn, Charles Rhodes, Scott Chiavacci, Jennifer Helgeson, Carl Shapiro, Crista Straub
Information plays a key role in the policy decision-making process – but the collection and dissemination of information carries costs. Understanding how these costs compare to the benefits of having the information (this is the value of information: "VOI"

Gauging the difficulty of image segmentation

May 19, 2022
Marek Franaszek
Image segmentation is the first step in a complex process of object recognition. This report presents a method to gauge the difficulty of segmentation by calculating a scalar parameter Q for an image. This parameter depends on a distribution of the

Intrinsically accurate sensing with an optomechanical accelerometer

May 18, 2022
Benjamin Reschovsky, David Long, Feng Zhou, Yiliang Bao, Richard A. Allen, Jason J. Gorman, Thomas W. LeBrun
We demonstrate a microfabricated optomechanical accelerometer that is capable of percent-level accuracy without external calibration. To achieve this capability, we use a mechanical model of the device behavior that can be characterized by the thermal

SCAP Composer User Guide
