Abstract Potential-based flows provide a simple yet realistic mathematical model of transport in many real-world infrastructure networks such as, e.g., gas or water networks, where the flow along each edge depends on difference potentials at its end nodes. We call network topology robust if maximal node potential needed to satisfy set demands never increases when are decreased. This notion robu...

A mathematical model of an acoustoelectric transducer based on the use electrokinetic phenomenon flow potential is proposed. It shown theoretically that increases in proportion to strength constant electric pumping field, which confirmed experimentally. The described converter has variable sensitivity. Rather large values sensitivity microphone have been obtained results work can be used design...
