Measurement Dataset for A Wireless Gantry System

This dataset includes the position data of a two-dimensional gantry system experiment in which the G-code commands for the gantry were transmitted through a wireless communications link. The testbed is composed of four main components related to the operation of the gantry system. These components are the gantry system, the Wi-Fi network, the RF channel emulator, and the supervisory computer. In the experimental study, we run a scenario in which the gantry tool moves sequentially between four positions and has a preset dwell at each of the positions. The wireless channel impact is produced through the RF channel emulator. First, we consider the benchmark channel with free-space log-distance path loss and ideal channel impulse response (CIR) which has no multi-path. Second, we consider a measured delay profile of an industrial environment where the CIR is experimentally measured and processed to be deployed using the channel emulator and to reflect the industrial environment impact. Moreover, time-varying log-normal shadowing is introduced due to the fluctuations in the signal level because of obstructions. The variance of zero-mean log-normal shadowing is set through the emulator. In order to collect the position information of the gantry system tool, we used a vision tracking system. In this dataset, we attached a meta_data.csv file to map various files to their corresponding parameters.  A README.doc file is included to describe the measurement apparatus.

Optimal Bayesian Experimental Design

Python module "optbayesexpt" uses optimal Bayesian experimental design methods to control measurement settings in order to efficiently determine model parameters.  Given a parametric model - analogous to a fitting function - Bayesian inference uses each measurement "data point" to refine model parameters.  Using this information, the software suggests measurement settings that are likely to efficiently reduce uncertainties.   A TCP socket interface allows the software to be used from experimental control software written in other programming languages. Code is developed in python and shared via GitHub's USNISTGOV organization.

Computation of 3-d matrices of maximal trace over rotations

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. Given a dxd matrix M, the problem of finding among all dxd rotation matrices U one such that UM is of maximal trace over rotation matrices is intricately related to the so-called constrained orthogonal Procrustes problem which is the least-squares problem that calls for a rotation matrix that optimally aligns two corresponding sets of points in d-dimensional Euclidean space. It is well known that computing an optimal U can be achieved with a method based on the computation of the singular value decomposition (SVD) of M.

The package consists of a Fortran program, a Matlab program, a Matlab mex file of the Fortran program, a compilation of the mex file, and a sample data file of 3x3 matrices. If a 3x3 matrix M is symmetric, without the SVD, the Fortran program computes an optimal 3x3 rotation matrix U for M with an approach based on a trigonometric identity. Otherwise, if M is not symmetric, part of the approach can still be used to compute U with the SVD. However, the option exists in the program to execute a procedure based on the Cayley transform and Newton's method that for each input matrix M computes a rotation matrix U such that UM is symmetric. If the procedure is successful (Newton's method didn't fail) a rotation matrix R (without the SVD) is computed as described above such that RUM is of maximal trace over rotation matrices. If Newton's method fails, then using the SVD, the program computes a rotation matrix R such that RM is of maximal trace over rotation matrices.

Note the following: (a) The option exists in the Fortran code to do everything using the SVD only. (b) If using the Cayley-Newton procedure in the Fortran code, an integer variable named ITEX is set to the maximum number of allowed iterations per input matrix of Newton's method. (c) The Matlab program can be used for the same purposes. The option also exists in the Matlab code to do everything using the Matlab version of the SVD method only. Otherwise the Matlab mex file of the Fortran program is used by the Matlab code. This has the effect of executing the Fortran code as described above from the Matlab code.

NIST's Integrated Colony Enumerator

This work involves only data processing software and does not involve data to publish. Data are acquired by the users of this software by the following methods. Two methods can be used to acquire images of agar plates with bacterial colonies grown. In the first, plates were placed on a flatbed scanner, covered by soft gloss paper (HP LaserJet soft gloss paper), and 8-bit grayscale images of the plates were obtained at 300 dpi (dots per inch; 118 dots per cm), 600 dpi (236 dots per cm), and 1,200 dpi (472 dots per cm). In the second approach, images are acquired with a digital camera. Images are acquired at the maximum resolution of the camera with no zoom. More details are described in the manual for the software.

Smart Manufacturing Systems Readiness Level (SMSRL) Tool

The Smart Manufacturing Systems Readiness Level (SMSRL) focuses on evaluating the readiness (also can be viewed as maturity) for a factory to undergo improvements, particularly related to the data intensive smart manufacturing technology deployment in a factory. The SMSRL uses the Factory Design and Improvement (FDI) activity model as a guide for indicating actions and things that should be in place for performing a successful smart factory transformation at the operational level. In the SMSRL, activities employed from the FDI are subdivided into their applicability at the various control levels of ISA-88: Enterprise, Site, Area, Process Cell, Unit, Equipment Module, and Control Module. Each activity is measured under multiple dimensions such as Activity Management, Designated Personnel, Software System, Output Data Format, KPIs and KPI relationship, all of which are grouped into 4 measurement categories (C1: Organizational Maturity, C2: IT Applications Maturity, C3: Performance Management Maturity and C4: Information Connectivity Maturity). Each of the measurement categories has its own calculation method to quantify the maturity level; and it is used for deriving customized factory improvement plans.

Note: The tool only works with Windows-based Microsoft Excel.

pyMCR: A Python Library for Multivariate Curve Resolution Analysis.

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. Finally, this library enables users to develop their own constraints, regressors, and error functions or import them from existing libraries.

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

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.  The results include sensor location, antenna height, probability of detection coverage, probability of false alarm for each Dynamic Protection Area (DPA), i.e., a predefined geographic area inside which radar may experience harmful interference.

Manufacturing Cost Guide

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:

-An organization is conducting research to reduce redundant engineering labor. How much do manufacturers spend on engineering?
-A researcher is proposing a project to reduce the use of steel by advancing material standards, thereby, reducing scrap caused from material deficiencies. How much do manufacturers spend on steel?
-A research organization is proposing to reduce energy consumption from machinery. How much is spent on energy for machine operation?
-An organization wants to promote energy efficient lighting in manufacturing facilities. How much do manufacturers spend on lighting?

Combustion Calorimetry Tool - NIST Standard Reference Database 206

Combustion calorimetry is the main method for the determination of enthalpies of formation for organic compounds. Rigorous application of the method uses a 100-step procedure, sometimes called Washburn corrections, to convert the experimental results into standard thermodynamic quantities. Because every laboratory uses its own in-house software implementing this procedure, which is often not available for verification or testing, it is difficult to fully assess experimental results. Furthermore, these programs often use obsolete reference values of thermodynamic properties. This Standard Reference Database (SRD) introduces a standard procedure for this conversion. All experimental data used in this procedure (second virial coefficients of gas mixtures, densities, solubilities of gases in water and electrolyte solutions, etc.) have been reviewed by NIST personnel and the most reliable values have been recommended. The working equations were revised where necessary. Consistent with the NIST efforts on developing publication standards, this SRD also provides a resource essential to reproducible publications and interlaboratory exchange of the combustion calorimetry results. The primary users are thermochemical laboratories worldwide. This SRD will also benefit current practitioners in industry and future investigators through incorporation into university coursework.  Please see the supporting publication for details: doi:10.1016/j.jct.2021.106425
