Franz Tscheikner-Gratl,Nicolas Caradot,Frédéric Cherqui,João P. Leitão,Mehdi Ahmadi,Jeroen Langeveld,Yves Le Gat,Lisa Scholten,Bardia Roghani,Juan Pablo Rodríguez,Mathieu Lepot,Bram Stegeman,Anna Heinrichsen,Ingo Kropp,Karsten Kerres,Maria do Céu Almeida,Peter M.

TL;DR: Sewer asset management gained momentum and importance in recent years due to economic considerations, since infrastructure maintenance and rehabilitation directly represent major investments as discussed by the authors. But it is still a relatively new area.
Journal ArticleDOI
Practical benchmarking of statistical and machine learning models for predicting the condition of sewer pipes in Berlin, Germany
Nicolas Caradot,Mathias Riechel,M. Fesneau,Nathalie Hernández,Andrés Torres,Hauke Sonnenberg,E. Eckert,N. Lengemann,J. Waschnewski,Pascale Rouault +9 more
TL;DR: Developing a set of clearly understandable metrics to assess the performance of sewer deterioration models from an end-user perspective and shows a strong potential for supporting operators in the identification of pipes in critical condition for inspection programs.
Journal ArticleDOI
Support tools to predict the critical structural condition of uninspected pipes for case studies of Germany and Colombia
TL;DR: Assessment of the prediction results of two models based on Logistic Regression and Random Forest methods for two different case studies found that the model based on RF was the one that could be useful as a support tool in the sewer asset management of both case studies.
Journal ArticleDOI
Arima as a forecasting tool for water quality time series measured with UV-Vis spectrometers in a constructed wetland
TL;DR: Hernandez et al. as mentioned in this paper used Arima (Autoregressive Integrated Moving Average) to predict water quality using time series recorded with UV-Vis spectrometers in a constructed wetland.
Journal Article
BIOADSORCIÓN DE CROMO (VI) POR LA CÁSCARA DE MAMEY (Mammea americana L.)
Ismael Acosta,Patricia Sandoval,Diana M Bautista,Nathalie Hernández,Juan F. Cárdenas,Víctor M. Martínez +5 more
TL;DR: In this paper, the authors studied the removal capacity of Chromium (VI) in solution by the mamey husk, using the diphenylcarbazide method to evaluate the metal concentration.
