In this paper, we combine coupled dipole approximation (CDA) theory with optimization codes based on cyclic coordinate descent minimization to obtain the best configurations of plasmonic nanoparticles that produce maximal scattering or absorption efficiencies in large-scale Vogel spiral arrays. The optimization is performed from the ultraviolet to the visible spectral range for different and commonly...
In arid and semi-arid regions, irrigation system optimization is very significant for rational water use. The optimized irrigation system of cotton in yuncheng district of shanxin, potatoes in Datong district was researched. By using Jensen model, with the goal of maximizing the benefit, the yield and benefit were calculated. The results showd that the water consumption of different economic crops...
In the case that water resources can not meet the irrigation water requirement, how to Irrigate according to the crop optimization irrigation time, maximize benefit of the limited water supply, is an important problem for agricultural sustainable development. So the concept of dynamic irrigation low limit was put forward. The dynamic irrigation low limit relates with crop growth and development time...
Cloud storage has gained increasing popularity in the past few years. In cloud storage, data is stored in the service provider's data centers, and users access data via the network. For such a new storage model, our prior wisdom about conventional storage may not remain valid nor applicable to the emerging cloud storage. In this paper, we present a comprehensive study and attempt to gain insight into...
Random third party quality audits are mandatory by the regulations for public construction projects in Taiwan. This project and auditor selection process is normally carried out based on personal experience and the quality of the selection outcome is hard to predict and control. This is a difficult work assignment problem because there are normally hundreds of projects and dozens of auditors to choose...
