According to flexibility of pneumatic conveying systems with respect to other types of transmission systems, this system has wide application in industry and agriculture processes. One important application of this system is in the loading and unloading tankers and powdery bulk materials such as trucks carrying cement, plaster and sand. Conveying efficiency is associated with pressure, which in...

We study a spline-based approximation of vector fields in the conservative case. This problem appears for instance when approximating current or wind velocity fields, the data deriving in those cases from a potential (pressure for the wind, etc..). In the modelling, we introduce a minimization problem on an Hilbert space for which the existence and uniqueness of the solution are provided. A con...
