frbca

Data provided by  National Institute of Standards and Technology

`{frbca}` is an R package supporting economic evaluation of functional recovery design for buildings. The goal of frbca is to conduct benefit-cost analysis (BCA) for buildings archetypes designed for functional recovery. The inputs include:

- Expected Annualized Losses (EALs) for (i) a baseline (code-conforming) design and (ii) recovery-based design interventions
- Structural and nonstructural costs for both (i) and (ii)
- A list of analysis parameters, including discount rate, time horizon, and economic analysis parameters such as business income

Standardized Approach for Assessing Wireless IoT Devices in Millimeter-Wave Industrial Work-Cell Channels

Data provided by  National Institute of Standards and Technology

In this paper, we present a standardized, repeatable test approach that replicates key features of measured industrial environments in a fully-characterized hybrid test chamber. The hybrid chamber consists of an anechoic chamber along with movable metallic spheres that provide discrete reconfigurable multipath components. The chamber is characterized by a synthetic-aperture system providing a reference measurement that captures the non-idealities of the chamber along with the intended spatial multipath, completing characterization of the test environment.

A computational framework (CHIPS-TB) for evaluating and comparing tight-binding parameterizations across diverse material systems relevant to semiconductor design, focusing on properties such as electronic bandgaps, band structures, and bulk modulus.

Data provided by  National Institute of Standards and Technology

The chipstb repository is a Python-based automation suite designed to systematically benchmark tight-binding electronic structure models (such as DFTB, TB3PY, and SlaKoNet) against high-accuracy Density Functional Theory (DFT) and experimental reference data. Built upon the JARVIS-Tools infrastructure, the code manages the complete workflow of retrieving crystal structures, executing semi-empirical calculations, and computing statistical error metrics for key properties like bandgaps and bulk moduli.

Water temperature, salinity, and other parameters collected by CTD from research vessel Sally Ride in the north Pacific Ocean off California from 2025-03-09 to 2025-03-15 (NCEI Accession 0309629)

Data provided by  National Oceanic and Atmospheric Administration

Cruise SR2504 by research vessel Sally Ride in March 2025 had the objective to service moorings for the CCE and CORC projects (California Current Ecosystem, Consortium on the Ocean's Role in Climate), with additional data collections en route in the Southern California Bight. To calibrate and validate the mooring data, CTD casts with water samples were collected. The CTD data are reported here. The CTD data have been quality-controlled and adjusted using the water sample data.

Water temperature, salinity, and other parameters collected by CTD from NOAA Ship Reuben Lasker in the north Pacific Ocean off California from 2024-03-28 to 2024-04-03 (NCEI Accession 0309630)

Data provided by  National Oceanic and Atmospheric Administration

Cruise RL-24-04 by NOAA Ship Reuben Lasker in March/April 2024 had the objective to service moorings for the CCE (California Current Ecosystem) project, as well as the CORC (Consortium on the Ocean's Role in Climate) project. To calibrate and validate the mooring data, CTD casts with water samples were taken. The CTD data are reported here. The CTD data have been quality-controlled and adjusted using the water sample data. The raw instrument data (*.xmlcon and *.hex files from the software by Sea-Bird Scientific) are provided as well.

Dissolved inorganic carbon, total alkalinity, nutrients, and other variables collected from profile and discrete observations during NOAA Ship Henry B. Bigelow cruise HB2401 (EXPOCODE 33HH20240217) in New York Bight, North Atlantic Ocean, Stellwagen Bank National Marine Sanctuary from 2024-02-17 to 2024-02-22 (NCEI Accession 0309660)

Data provided by  National Oceanic and Atmospheric Administration

This dataset contains profile discrete measurements of dissolved inorganic carbon, total alkalinity, pH on total scale, water temperature, salinity, nutrients, and oxygen collected during NOAA Ship Henry B. Bigelow cruise HB2401 (EXPOCODE 33HH20240217) in New York Bight, North Atlantic Ocean, Stellwagen Bank National Marine Sanctuary from 2024-02-17 to 2024-02-22. Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry ultimately resulting in a reduction in pH, a process termed ocean acidification.

Southern Makassar Strait, Indonesian Seas, coral Δ14C from 1952 to 1993 and Northern Lombok Strait coral Ba/Ca from 1905 to 2016 (NCEI Accession 0309661)

Data provided by  National Oceanic and Atmospheric Administration

There is one bimonthly coral Δ14C timeseries from the western Makassar Strait in the Indonesian Seas, and one bimonthly coral Ba/Ca record from the Northern Lombok Strait in the Indonesian Seas. These data were used to explore the climate drivers of biennial variability, namely the interaction of ENSO and the East Asian Winter Monsoon.
