The real-coded genetic algorithm (RGA) is used to determine an optimal set of current excitation weights of the antenna elements and the optimum inter-element spacing that satisfies the design goal.
From both characteristics the optimum die elements were optimized.
As so, d = λ/2 is the optimum inter-element spacing in the ULA configuration. Figure 1 Uniform linear array (ULA) geometry.
In finding optimum values, finite element analysis, response surface methodology and genetic algorithm are integrated.
Design and fabrication of an optimum holographic optical element (HOE) lens for a femtosecond laser pulse using a hologram computer-aided design (CAD) tool is presented.
A convergence study has been performed to arrive at an optimum number of elements and nodes to be used in the modeling.
Nitric and hydrochloric acid concentrations between 4.1 and 5.3 M, and between 2.8 and 3.8 M, respectively, were found as optimum for many elements (Ca, Cd, Cr, Cu, Fe, Mg, Mn, Pb and Zn) yielding the acid leaching process for times in the 1.2 2.2 min range.
Long fatigue life is the most important objective in the optimum design of rolling element bearing.
This demonstrates the advantages of the new methodology in being able to identify the optimum configurations for different element constraints.
