RF Dataset of Incumbent Radar Systems in the 3.5 GHz CBRS Band

Data provided by  National Institute of Standards and Technology

The RF dataset can be used to develop and test detection algorithms for the 3.5 GHz CBRS or similar bands where the primary users of the band are federal incumbent radar systems. The dataset consists of synthetically generated radar waveforms with added white Gaussian noise. The RF dataset is suitable for development and testing of machine/deep learning detection algorithms. A large number of parameters of the waveforms are randomized across the dataset. Due to its large size, the dataset is divided into groups, and each group consists of multiple files.

American Community Survey: 1-Year Estimates: Detailed Tables 1-Year

Data provided by  United States Census Bureau

The American Community Survey (ACS) is an ongoing survey that provides data every year -- giving communities the current information they need to plan investments and services. The ACS covers a broad range of topics about social, economic, demographic, and housing characteristics of the U.S. population. Much of the ACS data provided on the Census Bureau's Web site are available separately by age group, race, Hispanic origin, and sex.

NIST Nanocalorimeter DWG and DXF drawings for microfabrication mask generation

Data provided by  National Institute of Standards and Technology

Four files are included in this data set for mask generation that can be used to produce photolithography contact masks to create NIST nanocalorimeters. Two different designs are included, each in AutoCAD *.dwg format and a universal *.dxf format. The masks are intended to be printed on 5 inch masks blanks used to pattern 100 mm (4 inch) wafers.
