Timing Offset and Timing Stability for a Dual-Clock Channel Sounder

Data provided by  National Institute of Standards and Technology

This project is anticipated to generate Working Data, Derived Data, and Published Results. Working Data will comprise raw measurement information from channel sounder instruments or oscilloscopes. Our channel sounder records data in National Instruments proprietary binary (.tdms) format. Oscilloscope measurements will be recorded as ASCII spreadsheet (.csv) formats. Also among working data will be human-readable files containing experimental configurations and conditions for the collection of channel sounding data. These data are stored as spreadsheet (.xlsx) files.

Vintage 2018 Population Estimates: Demographic Characteristics Estimates by Age Groups

Data provided by  United States Census Bureau

Annual Resident Population Estimates by Age Group, Sex, Race, and Hispanic Origin: April 1, 2010 to July 1, 2018 // Source: U.S. Census Bureau, Population Division // The contents of this file are released on a rolling basis from December through June. // Note: 'In combination' means in combination with one or more other races. The sum of the five race-in-combination groups adds to more than the total population because individuals may report more than one race. Hispanic origin is considered an ethnicity, not a race. Hispanics may be of any race.

Vintage 2018 Population Estimates: Components of Change Estimates

Data provided by  United States Census Bureau

Annual Resident Population Estimates, Estimated Components of Resident Population Change, and Rates of the Components of Resident Population Change: April 1, 2010 to July 1, 2018 // Source: U.S. Census Bureau, Population Division // The contents of this file are released on a rolling basis from December through March. // Note: Total population change includes a residual. This residual represents the change in population that cannot be attributed to any specific demographic component.

2D Measurement of Retinal Pigment Epithelium Function Using Quantitative Bright-Field Microscopy

Data provided by  National Institute of Standards and Technology

Induced Retinal Pigment Epithelial (iRPE) implants were developed from two healthy donors (Healthy-1 and Healthy-2). Live iRPE were imaged using quantitative bright-field absorbance microscopy (QBAM) every week during the in vitro maturation process. The data are organized by the culture plate, imaging date and time, color filter used to capture the images, and finally images that include the well ID and grid position in the name of the image.

Process and robot data from a two robot workcell representative performing representative manufacturing operations.

Data provided by  National Institute of Standards and Technology

This data set is captured from a robot workcell that is performing activities representative of several manufacturing operations. The workcell contains two, 6-degree-of-freedom robot manipulators where one robot is performing material handling operations (e.g., transport parts into and out of a specific work space) while the other robot is performing a simulated precision operation (e.g., the robot touching the center of a part with a tool tip that leaves a mark on the part). This precision operation is intended to represent a precise manufacturing operation (e.g., welding, machining).
