After the analysis of variance, treatments were compared by means of orthogonal decomposition of the sum of squares of the treatments in linear, quadratic and cubic order effects related to the effect ...

A branch flow model (BFM) is used to formulate the AC power flow in general networks. For each branch/line, the BFM contains a nonconvex quadratic equality. A mathematical formulation of its convex ...

The author presents the formulation and solution method of an optimal power flow problem using a sequential quadratic programming technique for an AC-DC power system with one or more multiterminal DC ...

The experimental data were used to calculate the coefficients of the quadratic polynomial equation, which were used to predict the values of the particle size, zeta potential, PDI, encapsulation ...
