BIPM

Experts from various National Metrology Institutes (NMI) convened to discuss developments in measurement science—from quantum technology standards to the FAIR principles for data management in metrology—at #BIPM's recent two day NMI Directors’ Workshop. One of the most popular sessions was on the intersection of #AI and #metrology, focusing on how precise measurement can enhance the control and quality of AI systems. 𝐖𝐚𝐭𝐜𝐡 𝐭𝐰𝐨 𝐬𝐭𝐚𝐧𝐝𝐨𝐮𝐭 𝐩𝐫𝐞𝐬𝐞𝐧𝐭𝐚𝐭𝐢𝐨𝐧𝐬 𝐛𝐞𝐥𝐨𝐰: 🎬 Dr Agnes Delaborde from LNE's presentation "Enhancing Control of Generative AI through Metrology" focused on addressing AI bias, uncertainty and the importance of certification to reinforce accuracy and trustworthiness in AI outputs. (0:00) 🎬 Professor Dr. Tobias Schaeffter from Physikalisch-Technische Bundesanstalt, PTB's presentation "Data Quality Metrics and Reference Data for AI" highlighted the critical role of high-quality datasets and standardized metrics to strengthen AI reliability across applications. (19:00) Both talks underscored the essential role metrology will play in guiding AI development with the highest standards of precision and integrity. 📖 𝑹𝒆𝒂𝒅 𝒕𝒉𝒆 𝒇𝒖𝒍𝒍 𝒂𝒓𝒕𝒊𝒄𝒍𝒆 (linked to in the comments below) to explore how metrology is advancing the future of AI! | Bureau International des Poids et Mesures (BIPM) | #MetrologyMatters https://lnkd.in/exQziKJp

𝐀𝐝𝐯𝐚𝐧𝐜𝐢𝐧𝐠 𝐭𝐡𝐞 𝐀𝐜𝐜𝐮𝐫𝐚𝐜𝐲 𝐨𝐟 𝐀𝐂 𝐕𝐨𝐥𝐭𝐚𝐠𝐞 𝐂𝐨𝐦𝐩𝐚𝐫𝐢𝐬𝐨𝐧𝐬 The #BIPM and #NIST have successfully conducted a new pilot study, marking a significant advancement in the accuracy and reliability of ac voltage comparisons. This achievement represents a major step forward for on-site comparisons of ac voltages. 𝐊𝐞𝐲 𝐚𝐜𝐡𝐢𝐞𝐯𝐞𝐦𝐞𝐧𝐭𝐬 𝐨𝐟 𝐭𝐡𝐢𝐬 𝐬𝐭𝐮𝐝𝐲 𝐢𝐧𝐜𝐥𝐮𝐝𝐞: ➡Stability and reproducibility: The NIST JAWS system allowed the BIPM PJVS to be tested under a wide variety of configurations, pushing the limits of reliability of the differential sampling setup. ➡ Breakthrough in uncertainty: For the first time, the study achieved a Type A uncertainty (a measure of statistical uncertainty) of a few parts in 10⁹ for a 10 Hz sine wave at 2 V rms. At 1 kHz, a relative level of 2 × 10⁻⁷ was reached.

Honoured to be participating in the Workshop on 'Global and National Greenhouse Gas Monitoring Initiatives' at KRISS, Korea. The Workshop brings together experts in GHG measurement networks, instrumentation and standards and is identifying progress and collaborative opportunities to determine GHG emissions through concentration measurement both at urban and global scales. Key focus issues will be the development of metrology systems as integral components of operational systems to estimate greenhouse gas emissions based on accurate measurements and analyses. #BIPM #KRISS #WMO #IAEA #ICOS #ClimateAction #CCQM Sangil Lee

The origins of the metre explained on French radio 📻. Céline Fellag Ariouet (#BIPM) participated in the radio show Sciences Chrono on France Culture, hosted by Antoine Beauchamp, on 27 September 2024. The show was dedicated to a pioneering geodetic survey undertaken by Jean-Baptiste Delambre and Pierre Méchain in the 1790s that formed the basis of the original definition of the #metre. The radio show provided an opportunity to give listeners a history of the BIPM and the plans for the celebration of its 150th anniversary in 2025. A podcast of the show is available from the news story. #metrology #measurement https://lnkd.in/eAn-M4x2

The #BIPM and NIST (USA) are collaborating on the development of a new generation of Kibble balance. This joint work is being carried out in response to a recommendation of the Consultative Committee for Mass and Related Quantities (CCM) for more collaboration between the different Kibble balance teams. As part of this collaboration, NIST welcomed Dr Franck Bielsa from the BIPM Kibble balance group for five months in their team. The main purpose of the collaboration is the further development of the Kibble balance which is part of the Quantum Electro-Mechanical Metrology Suite (QEMMS) of NIST, which can provide quantum voltage, resistance, current, mass and force dissemination directly traceable to the new SI. The aim of the new generation of small-size Kibble balances is to provide mass realization in the 10 g – 200 g range. #metrology https://lnkd.in/eRqpX_fT
