Abstract Identification of coefficients determining flow resistance, in particular Manning’s roughness coefficients, is one of the possible inverse problems of mathematical modeling of flow distribution in looped river networks. The paper presents the solution of this problem for the lower Oder River network consisting of 78 branches connected by 62 nodes. Using results of six sets of flow measurements at particular network branches it was demonstrated that the application of iterative algorithm for roughness coefficients identification on the basis of the sensitivity-equation method leads to the explicit solution for all network branches, independent from initial values of identified coefficients.

We demonstrate the detailed analysis for conversion of piezoelectric properties into compliance matrix and simulate a series bimorph configuration for vibration based energy generation. Commercially available software COMSOL Multiphysics was used to apply boundary conditions for optimization of geometric parameters such as length, width and thickness of piezoelectric layer to study voltage and power characteristics of the harvester. The resulting energy harvester was found to generate 1.73 mW at 53.4 Hz across a 3MW load with an energy density of 13.08mJ/cm3. We also investigated feasibility of this model by comparing it with existing experimental data of known piezoelectric ceramic compositions and found good correlation between the two.
