Calibration Data for Wafer 2 of SRM 3461 - MEMS Cantilever Stiffness

Data provided by  National Institute of Standards and Technology

SRM 3461 is an AFM sized chip with an array of seven cantilevers on each chip. The uniformity of the chips offered for sale from wafer 2 is excellent and the SRM certificate reports values and uncertainties for the entire lot of chips for sale; however, this dataset provides the raw data used to certify the SRM. Since each chip is serialized, the raw data for a specific SRM chip can be accessed from this dataset. In addition to the laser Doppler vibrometry data and optical micrograph, this dataset contains the Mathematica code used to process the data.

Trojan Detection Software Challenge - nlp-question-answering-sep2021-train

Data provided by  National Institute of Standards and Technology

Round 8 Train DatasetThis is the training data used to construct and evaluate trojan detection software solutions. This data, generated at NIST, consists of natural language processing (NLP) AIs trained to perform extractive question answering (QA on English text. A known percentage of these trained AI models have been poisoned with a known trigger which induces incorrect behavior. This data will be used to develop software solutions for detecting which trained AI models have been poisoned via embedded triggers.

Aged and unaged ultra high molar mass polyethylene flexible unidirectional composite laminate tensile testing for soft body armor applications

Data provided by  National Institute of Standards and Technology

This dataset contains mechanical testing data at two different loading rates for two different aging conditions (wet and dry at 70 °C) for five different extraction time points for ultra high molar mass polyethylene (UHMMPE) unidirectional (UD) laminate. In each folder there is a spreadsheet (.csv) with the test data collected during loading, and a (.avi) video file for each of the tests done under those conditions.
