Harmony Search (HS) algorithm, explored in recent literature, is an efficient metaheuristic optimization technique based on the musical improvisation process. Different versions of HS have been developed and used in solving real-world problems; however, most of the applications are oriented to combinatorial optimization. This paper presents a novel application of a modified HS for the synthesis of a four-bar planar mechanism that follows a specific trajectory, in order to demonstrate the capabilities of this algorithm for handling numerical optimization problems. Four-bar mechanisms are a good example of hard optimization problems, since they are used in a wide variety of industrial applications. HS algorithm was modified to handle design constraints by implementing Deb's feasibility rules. Simulation results show a high-precision control of the proposed trajectory for the designed mechanism, thus demonstrating that HS can be applied successfully not only to classical benchmark problems but for solving real engineering cases.

This paper presents a model for a single-phase transmission line in the presence of corona effect and induced voltages, the latter due to external electromagnetic fields. The solution of the transmission line equations is proposed through the method of characteristics, which is based on the partial differential equations (PDEs) theory. Based on that theory, the Telegrapher's equations, consisting on a system of two PDEs, are transformed into ordinary differential equations (ODEs). The resultant nonlinear system of ODEs is numerically integrated along the characteristic curves, which implicitly fulfill the Courant-Friedrichs-Lewi (CFL) condition. In the modeling of corona, the capacitance has been taken as static, i.e., it does not depend on the rate of change of the voltage. This permits to use charge-voltage (qv) curves to represent the nonlinear phenomenon of corona. The induced voltages along the line have been calculated by using an incident nonuniform field. This field has two components, one in the direction of the ground and the second being orthogonal to the ground.
