Data tables for Energy Price Indices and Discount Factors for Life-Cycle Cost Analysis - 2022: Annual Supplement to NIST Handbook 135

Data tables for Energy Price Indices and Discount Factors for Life-Cycle Cost Analysis - 2022: Annual Supplement to NIST Handbook 13Starting in the 2022 Annual Supplement to Handbook 135, the data tables within the text document has been extracted and provided in a supplemental spreadsheet. The reasons for creating a separate data file is to (1) make the text document smaller and easier to navigate, (2) provide the data in a format that is more accessible to a user, particularly those that want to incorporate the data tables into their own calculations or tools, and (3) streamline the process for the annual release of the data.There are numerous data sources used in developing these data tables, including EIA, OMB, and Federal Reserve. Process is discussed in Annual Supplement to Handbook 135.

Reference Measurements of Error Vector Magnitude

The experiment here was to demonstrate that we can reliably measure the Reference Waveforms designed in the IEEE P1765 proposed standard and calculate EVM along with the associated uncertainties. The measurements were performed using NIST's calibrated sampling oscilloscope and were traceable to the primary standards.We have uploaded the following two datasets. (1) Table 3 contains the EVM values (in %) for the Reference Waveforms 1--7 after performing the uncertainty analyses. The Monte Carlo means are also compared with the ideal values from the calculations in the IEEE P1765 standard.(2) Figure 3 shows the complete EVM distribution upon performing uncertainty analysis for Reference Waveform 3 as an example. Each of the entries in Table 3 is associated with an EVM distribution similar to that shown in Fig. 3.

QICO2 Indoor Carbon Dioxide Metric Analysis Tool

Indoor carbon dioxide (CO2) concentrations have been used for decades to evaluate indoor air quality (IAQ) and ventilation, and more recently in discussions of the risk of airborne infectious disease transmission. However, many applications of indoor CO2 measurement reflect a lack of understanding of the connection between indoor CO2 levels, ventilation and IAQ. In many cases, an indoor concentration of 1000 ppmv has been used as a metric of IAQ and ventilation without an understanding of its basis or significance. After many years trying to dissuade practitioners and researchers from using this or some other single concentration as an overall metric of ventilation and IAQ, an approach has been developed to determine a space-specific CO2 level that can be used as an indicator of the outdoor ventilation rate. The concept is to estimate the CO2 concentration that would be expected in a specific space given its intended or expected ventilation rate per person, the number of occupants and the rate at which they generate CO2. A calculation method is described for estimating the CO2 concentration in a given space at selected times after occupancy starts, which provides a more meaningful metric than a single value for all spaces. An online tool (QICO2, Quick Indoor CO2) has been developed to perform these calculations, and this report also contains a User Guide for that tool.

Distributed Sensing of Radio Spectrum Occupancy Amid COVID-19

During the COVID-19 pandemic, National Institute of Standards and Technology (NIST) performed a targeted campaign of measurements of channel power and occupancy rate in the radio spectrum. This is the dataset that resulted from that effort.Measurements were performed in 13 residential sites after a rapid engineering development effort, followed by spot measurements at a local hospital. The study targeted radio frequency allocations that support key wireless data infrastructure. These included the cellular network bands below 1 GHz, and unlicensed bands that support wireless local-area network (WLAN) and wireless personal area network (WPAN) traffic in 2.4 GHz and 5 GHz bands. The principal test locations were the home telework sites of NIST research staff, postdoctoral researchers, graduate and undergraduate students, and summer high school interns. Measurements continued where possible from late spring in 2020 until the autumn of 2021.The resulting data are released here in the following forms:1) Time series of band power, integrated on 4-MHz bandwidth in 0.5 ms bins;2) Time series of band power, denoised to remove average additive noise produced by the receiver;3) Occupancy durations computed from the denoised band power time series;4) Histograms of band power readings computed from denoised band power time series; and5) Diagnostic network profiling data that indicates PHY characteristics of cellular and WLAN signals.

Complex Document Information Processing (CDIP) dataset

This dataset is called the "IIT CDIP collection".  "CDIP" stands for "Complex Document Information Processing" and "IIT" stands for "Illinois Institute of Technology" who originally built the dataset.  The dataset consists of documents from the states' lawsuit against the tobacco industry in the 1990s. As a result of the settlement of that lawsuit (the "Master Settlement Agreement"), the companies had to make all the documents public in an archive, which currently resides at UCSF, the University of California, San Francisco.IIT used this data to build a dataset of "messy" documents that were challenging for existing systems to process.  There is handwriting on the documents, stains, etc.  TREC used an automatic text conversion of this dataset in the TREC Legal Track, and we also have the original TIFF scans of the documents.  The dataset consists of around 7 million documents, preprocessed with 90s-era OCR, and also the original page scans in TIFF format. See contact information in this record for access to this dataset.

GIAB Benchmarking of HG002 Assemblies from HPRC Year 1 Bakeoff

The Human Pangenome Reference Consortium (HPRC) tested which combination of current genome sequencing and automated assembly approaches yields the most complete, accurate, and cost-effective diploid genome assemblies with minimal manual curation.  Assemblies were generated for GIAB HG002. Variant calls from twenty-nine assemblies were evaluated by NIST using dipcall v0.3 (https://github.com/lh3/dipcall) to produce variant calls when aligned to GRCh38.  Benchmarking of small variant calls was then performed against GIAB benchmark v4.2.1 using hap.py v3.12 (https://github.com/Illumina/hap.py).
