in this paper, the influence of the constituent volume fractions by changing the values of the power-law exponent with uniform pressure on the vibration frequencies of reinforced functionally graded cylindrical shells is studied. the fgm shell with ring is developed in accordance to the volume fraction law from two constituents namely stainless steel and nickel. these constituents are graded th...

Increasing renewable penetration in distribution grids calls for improved monitoring and control, where power flow (PF) model is the basis many advanced functionalities. However, unobservability makes traditional way infeasible to construct PF analysis via admittance matrix grids. While data-driven approaches can approximate mapping, direct machine learning (ML) applications may suffer from sev...
