    Phasage des travaux et organisations transitoires : quels rôles pour l’ergonome ? by François Daniellou, Jacques Escouteloup, Joffrey Beaujouan

    Published 2011-04-01
    “…Ergonomics has often focused on understanding the shift from Situation A to Situation B in an architectural context but has devoted less attention to the intermediate stages between A and B and their impact on occupants’ health and the efficiency of the establishment. This paper examines various examples of this type of project and suggests how ergonomists may help to reconcile continued operation and building work by: (1) encouraging the two professional groups to meet and discuss the issues, (2) using simulations to determine the broad outlines of the schedule, (3) helping occupants to define temporary organisation methods and (4) adjusting those forms of organisation to major stages in the schedule.…”

    Performance validation and calibration conditions for novel dynamic baseline tracking air sensors in long-term field monitoring by H. Mei, P. Wei, M. A. Ghadikolaei, N. K. Gali, Y. Wang, Z. Ning

    Published 2025-04-01
    “…The tests, which involved evaluating the validation performance by analysing randomly selected calibration sample subsets ranging from 1–15 d, indicated that the length of the calibration period, pollutant concentration range and time-averaging period are pivotal for sensor calibration quality. We determined that a 5–7 d calibration period minimizes calibration coefficient errors, and a wider concentration range improves the validation <span class="inline-formula"><i>R</i><sup>2</sup></span> values for all sensors, suggesting the necessity of setting specific concentration range thresholds. …”
