Microstrip and Grounded CPW Calibration Kit Comparison for On-Wafer Transistor Characterization from 220 GHz to 325 GHz

Data provided by  National Institute of Standards and Technology

Data published in paper "Microstrip and Grounded CPW Calibration Kit Comparison for On-Wafer Transistor Characterization from 220 GHz to 325 GHz"We investigated the effect of two uncertainty sources, probe placement error and capacitance per unit length variation, on transistor S-parameter measurements calibrated with two different mTRL calibration kits.

ssmdevices

Data provided by  National Institute of Standards and Technology

ssmdevices is a collection of python wrappers that have been used for automated experiments by the NIST Spectrum Technology and Research Division. They are released here for transparency, for re-use of the drivers as-is by the test community, and as a demonstration of lab automation based on labbench (see https://github.com/usnistgov/labbench).

2022 American Community Survey: 1-Year Estimates - Public Use Microdata Sample

Data provided by  United States Census Bureau

The American Community Survey (ACS) Public Use Microdata Sample (PUMS) contains a sample of responses to the ACS. The ACS PUMS dataset includes variables for nearly every question on the survey, as well as many new variables that were derived after the fact from multiple survey responses (such as poverty status). Each record in the file represents a single person, or, in the household-level dataset, a single housing unit.

2022 American Community Survey: 1-Year Estimates - Public Use Microdata Sample Puerto Rico

Data provided by  United States Census Bureau

The Public Use Microdata Sample (PUMS) for Puerto Rico (PR) contains a sample of responses to the Puerto Rico Community Survey (PRCS). The PRCS is similar to, but separate from, the American Community Survey (ACS). The PRCS collects data about the population and housing units in Puerto Rico. Puerto Rico data is not included in the national PUMS files. It is published as a state equivalent file and has a State FIPS code of "72".

Noise Datasets for Evaluating Deep Generative Models

Data provided by  National Institute of Standards and Technology

Synthetic training and test datasets for experiments on deep generative modeling of noise time series. Consists of data for the following noise types: 1) band-limited thermal noise, i.e., bandpass filtered white Gaussian noise, 2) power law noise, including fractional Gaussian noise (FGN), fractional Brownian motion (FBM), and fractionally differenced white noise (FDWN), 3) generalized shot noise, 4) impulsive noise, including Bernoulli-Gaussian (BG) and symmetric alpha stable (SAS) distributions.

Daily visual surf observations on Oahu, Hawaii, USA of the Goddard-Caldwell collection starting 1968 (NCEI Accession 0001754)

Data provided by  National Oceanic and Atmospheric Administration

Surf reports are typically made several times per day at select locations around Oahu, primarily by Honolulu City and County lifeguards and the Surf News Network, Inc. Wave heights are reported in Hawaii scale, Hs, which systematically underestimates breaker size by as much as one-half. Although exactly when and why this tendency originated is highly disputed, it became the primary means of communicating surf size by the late 1960s. From publicly available surf reports and other notes from reputable surfers, Mr. Larry Goddard logged heights from 1968 through September 1987 and Mr.

Surf observations from the South Shore of Oahu, Hawaii, from 1972-03-01 to 1987-11-20 (NCEI Accession 0000274)

Data provided by  National Oceanic and Atmospheric Administration

Heights of breaking surf were collected by using visual observations from swimmers or divers at the South Shore of Oahu, Hawaii from March 1, 1972 to November 20, 1987. Data were submitted by University of Hawaii, Honolulu.

CTD data from 5 stations collected on an R/V Lowell Weicker cruise in Fisher's Island Sound (NY/CT) in 2012 (NCEI Accession 0278801)

Data provided by  National Oceanic and Atmospheric Administration

This dataset contains biological, optical, and physical data collected on R/V Lowell Weicker during cruise LW_053012 on 2012-05-30. These data include depth, fluorescence, salinity calculated from CTD primary sensors, sigma-t, and water temperature. The instruments used to collect these data include CTD Sea-Bird SEACAT 19. These data were collected by Dr Laura A. Katz of Smith College and Dr George B. McManus of University of Connecticut as part of the "Diversity and dynamics of planktonic ciliates - what can next-generation sequencing technologies tell us?
