Implementation and Verification of Fresnel Zone Plate Patterns Designed by Optimization of Surface Phase [PDF]
한국정밀공학회지In this study, we present a numerical simulation approach for designing Fresnel zone plate (FZP) patterns. By optimizing surface phase parameters using desired merit functions in ray-tracing software, the obtained surface phase was converted into an FZP ...

A Co-simulation Procedure for Optimal Reactive Power Control in Active Distribution Networks
2023 IEEE International Conference on Environment and Electrical Engineering and 2023 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2023 Distribution grids are subject to a drastic evolution in their operating conditions due to the high integration of renewable energy resources (RES) and their ability to regulate voltage. To cope with this issue, modern solar photovoltaic (PV) systems are equipped with smart inverters enabled with communication capabilities that allow the coordinated ...

Computer Simulation for the Simultaneous Optimization of Any Two Variables and Any Chromatographic Procedure [PDF]
Journal of Chromatographic Science, 2000 Computer software that allows the simulation of any chromatographic separation as a function of simultaneous changes in any one or two variables that can affect sample separation order (selectivity) is described. For one example, an application is described for the simultaneous variation of the mobile phase pH and gradient time in reversed-phase liquid
