Manufacturing Cost Guide

Data provided by  National Institute of Standards and Technology

The Manufacturing Cost Guide is a tool that estimates the costs that US manufacturers face and can be used to help gauge the potential returns on manufacturing industry research projects through cost reductions. These costs are grouped into various standardized categories such as the North American Industry Classification System (NAICS) and the Standard Occupational Classification (SOC) system along with other non-standardized costs.

The tool can be used to answer questions such as:

Analytical Modeling of White Space Utilization for a Dynamic Spectrum Access System

Data provided by  National Institute of Standards and Technology

This dataset contains the result from simulation experiments carried out for our study of analytical modeling of white space utilization for a Dynamic Spectrum Access (DSA) system. It contains the data for the results obtained while comparing analytical and simulated white space utilization (WSU) for synthetic data. It also contains Q-Q plot data which was used to show that the data collected from the metro Philadelphia area is approximately exponentially distributed. It has the histogram of channel 15 and 16 of Philadelphia LTE uplink data.

A Practical Approach to Placing Coastal Sensors for Spectrum Sharing in the 3.5 GHz Band

Data provided by  National Institute of Standards and Technology

This dataset contains the results of simulated deployments of Environmental Sensing Capability (ESC) sensors along the coasts of the contiguous United States in the 3.5 GHz band. Commercial-federal spectrum sharing in the 3.5 GHz band requires the ESC sensors to detect federal incumbent shipborne radar in order to protect it from harmful interference from commercial users. We use existing tower sites as candidate locations for the sensors and the Irregular Terrain Model (ITM) in point-to-point mode to compute the path loss.

pyMCR: A Python Library for Multivariate Curve Resolution Analysis.

Data provided by  National Institute of Standards and Technology

pyMCR is an open-source software library for performing multivariate curve resolution (MCR) analysis with an alternating regression scheme (MCR-AR). MCR is a chemometric method for elucidating signatures of analytes and their relative abundance from a series of mixture measurements, without any knowledge of these values a priori. This software library, written in Python, enables users to perform MCR analysis with their choice of constraints, regressors, and error functions to minimize. Further, users can apply different constraints and regressors for signature and abundance calculations.
