Reference functional model for production in a circular economy

Data provided by  National Institute of Standards and Technology

Reference functional model for the activities and processes involved in production (e.g., designing, manufacturing, and recovering products/materials) in a circular economy. The model includes inputs and outputs of each activity, as well as factors that constrain and enable the activities (controls and mechanisms), using the IDEF0 methodology. It provides a baseline scenario that is relevant for stakeholders across product development and supply chain, including business strategists, material suppliers, designers, manufacturers, consumers, and recovers/recyclers.

Data associated with "Two-dimensional imaging of electromagnetic fields via light sheet fluorescence imaging with Rydberg atoms"

Data provided by  National Institute of Standards and Technology

Data associated with the publication: "Two-dimensional imaging of electromagnetic fields via light sheet fluorescence imaging with Rydberg atoms"Abstract:The ability to image electromagnetic fields holds key scientific and industrial applications, including electromagnetic compatibility, diagnostics of high-frequency devices, and experimental scientific work involving field interactions. Generally electric and magnetic field measurements require conductive elements which significantly perturb the field.

Determining angle of arrival of radio frequency fields using subwavelength, amplitude-only measurements of standing waves in a Rydberg atom sensor

Data provided by  National Institute of Standards and Technology

Deep subwavelength RF imaging with atomic Rydberg sensors has overcome fundamental limitations of traditionalantennas and enabled ultra-wideband detection of omni-directional time varying fields all in a compactform factor. However, in most applications, Rydberg sensors require the use of a secondary strong RF referencefield to serve as a phase reference. Here, we demonstrate a new type of Rydberg sensor for Angle-of-Arrival(AoA) sensing which utilizes subwavelength imaging of standing wave fields.

Sim-PROCESD: Simulated-Production Resource for Operations and Conditions Evaluation to Support Decision-making

Data provided by  National Institute of Standards and Technology

Sim-PROCESD is a discrete event simulation package written in Python that is designed to model the behavior of discrete manufacturing systems. Specifically, it focuses on asynchronous production lines. It also provides functionality for modeling the degradation and maintenance of machines in these systems. Sim-PROCESD provides class definitions for manufacturing devices/components that can be configured by the user to model various real-world manufacturing systems.

Data related to the investigation of UUIDs for a standards-based digital thread of product data in ISO 10303-242

Data provided by  National Institute of Standards and Technology

This dataset contains data used in the investigation of Universally Unique Identifiers (UUIDs) that will enable a standards-based digital thread of product data in ISO 10303-242. Included are EXPRESS schema used for implementation and .stp files that were exported from native CAD (CATIA V5, Creo, and NX). UUIDs were assigned to CAD features during .stp export for each of the four design iterations.

Rydberg Atom Electrometry: Recent Sensitivity and Bandwidth Improvements

Data provided by  National Institute of Standards and Technology

We present recent improvements within the growing field of Rydberg atom sensors. While initially started as a path towards absolute, independent measurements of electric fields, the research landscape has evolved into the realm of quantum sensors and receivers. We discuss the capabilities and limitations of Rydberg atom receivers, and we show how different atomic properties enhance or limit sensitivity and bandwidth.This data is for a review paper. Figures 6 (a) and 8 (a) and (b) are new data. The rest of the data is extracted from other NIST publications that have a data management plan.

Dataset presenting improved bandwidth in Rydberg atom electrometry with an optical frequency comb probe

Data provided by  National Institute of Standards and Technology

Rydberg atom-based receivers of modulated radio frequency (RF) fields are promising systems for measurements. These systems are self-calibrating, widely tunable, nearly transparent to RF fields, and can be electrically small. However, the instantaneous bandwidth of current Rydberg atom receivers is typically less than 1 MHz.

Dataset demonstrating feasibility of two-ladder sensing approach

Data provided by  National Institute of Standards and Technology

Datasets included in manuscript on simultaneous two-ladder sensing, titled "Independent Rydberg Atom Sensing using a Dual-Ladder Scheme" to be submitted to Applied Physics Letters. The data for figure 1 contains experimental EIT traces for both ladders, and figure 2 contains the data for false-color plots showing the polarization-specific response of each ladder.

Data and code for the paper, "Inverse Transform Sampling for Efficient Doppler-Averaged Spectroscopy Simulations"

Data provided by  National Institute of Standards and Technology

This dataset represents the results of calculations of atomic absorption spectra for the case of two-color EIT. We compare computation methods, specifically Gaussian sampling, to find that one sampling method converges to smooth transmittance curves in less time than the other. We also include some example scripts which generate and plot the figure data.

Data for the paper "EIT spectra of Rydberg atoms dressed with dual tone radio-frequency fields"

Data provided by  National Institute of Standards and Technology

This dataset contains the data for the figures in the paper "EIT spectra of Rydberg atoms dressed with dual tone radio-frequency fields", submitted to Physical Review A. This dataset can be used to recreate the experimental and theory plots from the CSV files. The data show EIT spectra of Rydberg atoms driven with dual-tone RF fields (experimental), and Floquet spectra of numerical models that are used to model these EIT spectra (theory/numerical).
