Microlens arrays film fabricated by UV roll-to-roll nanoimprinting lithography is introduced on glass substrate to improve the out-coupling efficiency of organic light-emitting devices. The microlenses suppress wave guiding loss in the substrate and a theoretical model, based on Monto-Carlo model, is developed to simulate the enhancement effects. The numerical results show that ellipsoidal-like microlens...
A reflective-type color filter in the visible range is theoretically investigated. It consists of a transparent flexible substrate, a layer of thick metal, and two-dimensional dielectric-metal grating. The filter proposed here has the advangtages of insensitivity to incident-angle and polarization-independence. It is found that the variations of its geometric parameters can tune the selective wavelength...
In this paper we consider a hybrid inventory system with manufacturing and remanufacturing. Characteristic and the influence factor of Inventory control in HMRS (hybrid manufacturing/remanufacturing system) was analyzed. Inventory control in HMRS with stochastic demand and return was studied. Presently, there are two main types of inventory replenishment strategies, which are called PUSH control strategy...
