Measurement and Uncertainty Analysis of Pressure Losses in a Push-to-Connect Elbow and Coupling The data on pressure losses in an elbow and a coupling are reported for Reynolds number (Re) from approximately 104 to 105. Both fittings selected for testing
Deterioration of concrete foundations due to pyrrhotite oxidation has led to several studies to better understand its reaction mechanisms, develop methodologies to identify potentially reactive aggregates, and quantify the influence of mixture formulations
Concrete is the second most used substance in the world after water. Concrete manufacturers produce 14 billion cubic meters annually, with a market size of $440 billion. The concrete industry is developing new technologies to decrease its carbon footprint

Traditional data storage formats and databases often introduce complexities and inefficiencies that hinder rapid iteration and adaptability. To address these challenges, we introduce ParquetDB, a Python-based database framework that leverages the Parquet
The Global Positioning System (GPS) is the most prevalent Global Navigation Satellite System (GNSS) that provides Position, Navigation, and Timing (PNT). GNSS vulnerability is well-known, and the search continues to find another independent system that can
The "Additive Construction – The Path to Standardization II" workshop, hosted by the National Institute of Standards and Technology (NIST) and U.S. Army Engineer Research and Development Center (ERDC), brought together key players from the additive

One of the most common polymers in commercial photovoltaic (PV) backsheets is polyvinylidene fluoride (PVDF). However, recent reports have shown the potential for PVDF-based backsheets to crack and fail prematurely. Previous work has suggested that polymer
This paper introduces a set of cellular vehicle-to-everything (C-V2X) datasets collected at the National Institute of Standards and Technology (NIST) Internet of Thing (IoT) Devices Interoperability Testbed. These datasets can be used to display, analyze
