Fabrication Of Various Curved Relief Structures Through Concave Surface Forming And Soft Replica Molding, Fang-Tzu Chuang
Fabrication Of Various Curved Relief Structures Through Concave Surface Forming And Soft Replica Molding, Fang-Tzu Chuang
Fang-Tzu Chuang
In this case, our groups presented various optical structures through the presented method, involving concave surface forming and soft replica molding. The method of concave surface forming is mainly for the fabrication of concave surface. The method of soft replica molding is mainly for the fabrication of replica. Concave and convex relief structures, including circular curved relief structures, convex relief structures with platform structures on the top, refractive beam-shaping elements, these structures with dual curvatures and asymmetric structures, can be easily made through the presented method, respectively. All processes of manufacture are in several simple steps without multistep optical lithography …

Impact Of Interconnection Photovoltaic/Wind System With Utility On Their Reliability Using A Fuzzy Scheme, Dr. Adel A. Elbaset
Dr. Adel A. Elbaset
Reliability analysis has been considered as an important step in any system design process. a reliable electrical power system means that the system which having sufficient power to feed the load demand during a certain period or in other word, having small Loss of Load Probability (LOLP). LOLP is defined as an expected fraction of load not met by its needed power from electrical power system during its lifetime. Photovoltaic (PV) / Wind Energy System (WES) hybrid electric power system (PV/WES HEPS) differs considerably from the utility grid (UG) in their performance and operating characteristics. With the interconnection of PV/WES …
