The American Community Survey (ACS) is a uswide survey designed to provide communities a fresh look at how they are changing. The ACS replaced the decennial census long form in 2010 and thereafter by collecting long form type information throughout the decade rather than only once every 10 years. Questionnaires are mailed to a sample of addresses to obtain information about households -- that is, about each person and the housing unit itself.

Nonemployer Statistics is an annual series that provides subnational economic data for businesses that have no paid employees and are subject to federal income tax, and have receipts of $1,000 or more ($1 or more for the Construction sector). The data consist of the number of businesses and total receipts by industry. Data are published by legal form of organization (U.S. and state only) and receipts-size class of establishments (U.S. level only).

This software is a Python module for estimating uncertainty in predictions of machine learning models. It is a Python package that calculates uncertainties in machine learning models using bootstrapping and residual bootstrapping. It is intended to interface with scikit-learn but any Python package that uses a similar interface should work.

The data and code that accompanies the book chapter Bayesian Hierarchical Models for Service Life Prediction of Polymers.

The programs here compute 3x3 matrices of maximal trace over rotation matrices from input matrices. A dxd matrix M is of maximal trace over rotation matrices if given any dxd rotation matrix U, the trace of UM does not exceed that of M.

This tariff search tool allows users to find tariff information on specific industrial goods covered under the U.S. FTAs. The tool shows the tariff applied on the date the FTA enters into force and the rates each subsequent year as the tariffs are eliminated under the agreement.

Cyber-physical systems are systems governed by the laws of physics that are tightly controlled by computer-based algorithms and network-based sensing and actuation. Wireless communication technology is envisioned to play a primary role in conducting the information flows within such systems. A practical industrial wireless use case involving a robot manipulator control system, an integrated wireless force-torque sensor, and a remote vision-based observer is constructed and the performance of the cyber-physical system is examined.

Supporting information documents for Brignac et al manuscript entitled, "Marine Debris Polymers on Main Hawaiian Island Beaches, Sea Surface, and Seafloor." Files include raw data tables of each debris item that was categorized and measured as well as additional figures of interpreted data.

Annual Housing Unit Estimates for the United States, States, and Counties // Source: U.S. Census Bureau, Population Division // Note: The estimates are based on the 2010 Census and reflect changes to the April 1, 2010 housing units due to the Count Question Resolution program and geographic program revisions.

Federal Communications Commission rules for the 3.5 GHz citizens broadband radio service (CBRS) permit commercial systems to share 150 MHz of bandwidth with federal and other incumbents. To protect the federal incumbents, a spectrum coordinator?the spectrum access system (SAS)?uses a standardized algorithm to suspend some commercial transmissions when a nearby incumbent (e.g., a shipborne radar) becomes active.
