Evaluation of biotreatability of ionic liquids in aerobic and anaerobic conditions

by IWA Publishing  (Aug. 13, 2014)

The aim of our study was to set up an approach for reliable biotreatability assessment of ionic liquids (ILs). As a case study, two different ILs were selected: pyridinium-based 1-butyl-3-methylpyridinium dicyanamide ([bmpyr][dca]) and imidazolium-based 1-butyl-3-methylimidazole tetrafluoroborate ([bmim][BF4]). Toxicity in aerobic conditions was ...

Signal analysis and anomaly detection for flood early warning systems

by IWA Publishing  (Sep. 25, 2014)

We describe the detection methods and the results of anomalous conditions in dikes (earthen dams/levees) based on a simultaneous processing of several data streams originating from sensors installed in these dikes. Applied methods are especially valuable in cases where lack of information or computational resources prohibit computing the state of ...
