Central Prediction System for Time Series Comparison and Analysis of Water Usage Data
Revenue water flow is defined as the amount of water for which the water rate has been collected, against tap water production, whereas non-revenue water (NRW) is defined as water that has been produced, but for which payment cannot be charged.

Determinants of non-revenue water for a water utility in California [PDF]
AbstractPhysical, technical, managerial, and environmental factors are all known to influence non-revenue water (NRW) volume, so a better understanding of these factors is important if we are to intervene in water loss problems more effectively. This study therefore identified determinants of NRW for a water utility in California by applying fixed ...

Mucoadhesive amphiphilic block and statistical copolymers were synthesized via Reversible Addition–Fragmentation Chain Transfer polymerization from bio‐sourced myrcene and polyethylene glycol methacrylate. The resulting polymers exhibit narrow molar‐mass distributions, high regioselectivity, well‐defined microstructures, and tend to self‐assemble into ...

Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...
