This paper describes the experimental determination of the absolute roughness of concrete conducts in a pressurized water supply network related to agricultural irrigation. Based on the Colebrooke-White equation and using a Monte Carlo method, the following estimates and 95 % expanded measurement uncertainties were obtained for a circular concrete conduct with an inner diameter of 1,2 m: 0,060 mm ± 0,055 mm and 0,021 mm ± 0,024 mm, for a water flow Reynolds number, comprised between 1,7·105 and 5,1·105, respectively. The output probability distribution showed a non-symmetrical shape, and the volumetric flow and pressure drop measurements were identified as the main contributions to the obtained dispersion of roughness values.

Beginning in 2022, NIST began a project called The Digital NIST which aims to make our measurement services - calibrations, standard reference materials, standard reference data - fully digital and fully FAIR. We reported on this work previously but provide here an update on further progress and prospects for future developments.

An innovative system has been developed, named PICUS (the woodpecker in Latin), and inspired by the auscultation method carried out by the experts in the field of conservation of cultural heritage. This device gently knocking the surface, controlling, acquiring and measuring some relevant parameters. In a nutshell, it performs an analysis similar to that carried out by a professional who performs a routine examination on the detachments by hand. The experimental apparatus consists of a probe made of an electromechanical percussion element that gently taps the surface producing a sound, an accelerometer to measure the impact force, and a microphone, all connected with an Arduino-like low cost board, to record and elaborate the sounds and the force sensor signal. The probe XY position on the scene is recognized using a low-cost IR camera positioned in the probe and an IR light-emitting diode opportunely positioned outside.

Samshvilde represents one of the most representative Georgian archaeological sites thanks to its complex history that began in the Neolithic times and ended in the 18th cent. The area has been always considered an important crossroads for its geographical position, and, for this, rich in different kinds of artefacts from pottery, obsidian objects, bronze coins to other furnishings. This variety testifies to the progress of the different civilizations over time in terms of culture, lifestyle, and technological skills. In the paper, two bronze coins were investigated to determine the main technological process used in the area during the Medieval Age and to increase the knowledge of metallurgical manufacture in the South Caucasus region that is still partly to be discovered.

This paper presents a multi-analytic study conducted as part of the IDHEA project at the former Tuna Factory Florio, an architectural complex situated on the captivating island of Favignana within the Egadi Islands, Trapani, Sicily, Italy. As a 19th-century industrial archaeology pole, this site stands as an intriguing nexus of architecture, museum exhibits, and cultural significance, rendering it an ideal experimental ground for pioneering methods and technologies aimed at preserving, managing, and enhancing cultural heritage. Given its coastal location, the structures are highly susceptible to marine, geomorphological, and environmental threats, intensifying material degradation risks. In this study, different approaches were adopted for the inspection, decay assessment and architectural survey of the building complex, including 3D architectural surveys via terrestrial laser scanning, drone-based RGB photogrammetry, multispectral data collection, and direct inspections. This integration yields comprehensive data and intricate 3D models, aiding in pinpointing specific vulnerabilities. The study culminates in the implementation of a GIS platform that harmonizes all data, serving as a pivotal resource for managing and preserving this historically significant site.
