It is now online my paper about Distributed Pressure Driven model, which presents an innovative approach for accurate simulations of water distribution systems. Thanks to the co-author Diego Avesani for his effort, and to my mentor prof. Maurizio Righetti for his guide in the research field. Global Gradient Algorithm Extension to Distributed Pressure Driven Pipe Demand Model. https://link.springer.com/article/10.1007/s11269-018-2174-3
