Community‐Derived Standards for LA‐ICP‐MS U‐(Th‐)Pb Geochronology – Uncertainty Propagation, Age Interpretation and Data Reporting

Geostandards and Geoanalytical Research, Volume 40, Issue 3, Page 311-332, September 2016., 2016
Key points New community‐derived LA‐ICP‐MS U‐(Th‐)Pb geochronology uncertainty propagation workflow defined, allowing better representation of absolute age uncertainties and better resolution of relative age differences within samples. New reference values defined for commonly used U‐Pb reference materials. New data‐reporting standards defined for more

Beyond the Metrics: Context‐Aware Calibration for Better Drain Flow Modelling

Irrigation and Drainage, Volume 75, Issue 2, Page 659-668, April 2026.
ABSTRACT Robust hydrological and water quality modelling is essential for advancing the understanding and management of engineered agricultural subsurface drainage systems. Achieving credible model output hinges on calibration strategies that are both rigorous and context sensitive. At the field scale, accurately capturing the dynamics of nutrient load

Development and Testing of a Low‐Cost Soil Moisture Sensor for Real‐Time Irrigation Scheduling

Irrigation and Drainage, Volume 75, Issue 1, Page 173-187, February 2026.
ABSTRACT Effective irrigation scheduling is essential for improved water management in irrigated areas, with soil moisture monitoring recognized as one of the most effective methods. However, challenges such as the high cost of sensors and the difficulties in monitoring large areas hinder their practical application, particularly for smallholder ...

Evaluation of CERES‐Maize Model for Predicting Yield, Evapotranspiration, Water Productivity and Drought Stress Indices Under Center Pivot, Subsurface Drip and Furrow Irrigation Systems With Different Irrigation Levels Simultaneously

Irrigation and Drainage, Volume 75, Issue 1, Page 372-389, February 2026.
ABSTRACT The effects of different irrigation methods (center pivot [CPI], subsurface drip [SDI] and furrow irrigation [FI]) and levels (full irrigation treatment [FIT], 80% FIT, 60% FIT and rainfed) on yield, crop evapotranspiration (ETc), ET‐water productivity (WPET) and drought stress index for leaf expansion (SIE) and photosynthesis (SIP) of maize ...

Comparison of the AquaCrop and CERES‐Maize models for simulating maize phenology, grain yield, evapotranspiration and water productivity under different irrigation and nitrogen levels

Irrigation and Drainage, Volume 73, Issue 3, Page 1052-1068, July 2024.
Abstract The CERES‐Maize and AquaCrop models were evaluated for their performance in simulating maize (Zea mays L.) phenology, evapotranspiration (ETc), grain yield and crop water productivity (CWP). Model input data for calibration, validation and simulations were obtained from field experiments conducted from 2011 to 2014 that imposed three different

Evaluation par la méthode inverse des cinétiques de séchage d’un lit fixe de particules

Revue des Énergies Renouvelables, 2015
Dans ce travail, on utilise la tomographie de capacitance électrique (ECT) pour déterminer les cinétiques de séchage d’une couche mince de la silice. Cette technique est une modalité d’imagerie électrique dans laquelle la répartition de la permittivité à

Etalonnage de caméras catadioptriques hyperboloïdes

, 2005
Cet article présente une procédure d'étalonnage pour les caméras panoramiques catadioptriques utilisant un miroir hyperbolique de révolution. L'algorithme que nous avons développé permet un étalonnage automatique (sans intervention d'un opérateur) des paramètres intrinsèques et extrinsèques de la caméra.
