A Point Process Model for Evacuation Flows: The Hawkes Mode

Ongoing
Results from a case study of evacuations of 14 office and residential buildings in the United States led us to model occupant exit times as a Hawkes point process, N(t). N(t) the number of evacuee exits in the time interval (0,t]. Because the Hawkes model is self-similar, human to human interaction...

Polymer Analytics

This project focuses on a variety of activities to achieve the aforementioned goal of accelerating the discovery of new polymer physics. Enhanced machine learning Two major hurdles to applying machine learning to polymer science is a lack of large datasets and a need to understand the model...

Publishing Services

Ongoing
The NIST Research Library occupies the unique position of serving NIST both as publisher of the NIST Technical Series, and in an archival capacity, responsible for collecting and preserving copies of NIST's grey literature. Over the last 15 years, the Library's publishing services have evolved from...

Quantifying Uncertainty in Accelerometer Sensitivity Studies

Ongoing
DESCRIPTION: International Key Comparisons are performed. The key comparison reference value for charge sensitivity as a function of frequency and the accompanying uncertainty are the principal objectives of these studies. In a suggested mixed effects model several methods for evaluation of this...

Radiative Decay of the Neutron

Ongoing
When a neutron decays by its radiative decay (RDK) mode, it produces a photon with a energy spectrum predicted by Quantum Electrodynamics. These RDK photons deposit energy in scintillators which produce voltage pulses in Avalanche Photo Diodes. We are developing nonlinear calibration models to...

Research Data Framework (RDaF)

Ongoing
What is the Research Data Framework? A map of the research data space: who, what, where, why, when? A dynamic guide for the various stakeholders in research data to understand best practices for research data management and dissemination A resource for understanding costs, benefits, and risks...

Research on Statistical Methods Project

Ongoing
The division typically produces one to a few publications on new statistical methods each year. A list of publications on some research from the past few years is shown below below. Following the publication list, an example of current work on the development of novel statistical methods, useful...

SED Consulting Program

Ongoing
