    An Analysis of the Quality of Repeated Plate Load Tests Using the Harmony Search Algorithm by Kook-Hwan Cho, Sungho Mun

    Published 2014-01-01
    “…The results of RSPLTs depend on the experience and expertise of the engineer carrying out the test, as well as the loading device, hydraulic jack assembly, and bearing plates. To identify outlier data points, well-tested data were used to develop a characteristic function model using a harmony search algorithm error minimization technique. …”

    Gouverner un territoire de l’eau à partir de considérations sur les savoirs liés à la production du paysage by Jacques-Aristide Perrin

    Published 2019-06-01
    “…Following a study carried out between 2014 and 2017 monitoring operations of ecological continuity in the Dordogne and Têt catchment areas, we analysed the consequences of this type of operation on landscapes and on water uses, which sometimes involve significant modifications in the case of the destruction of hydraulic works. Given how landscape issues are addressed in the implementation of this policy, its current framework does not make it possible to depart from a sector-based management approach focused on biodiversity. …”
