To help users clarify what they prefer more easily, in this work, we propose a novel recommender named FRSA (Fusion of Rough-Set and Average-category-rating) that integrates multiple contents and collaborative information to predict user’s preference based on rough-set theory. The major contribution of this paper is that our proposed recommender can successfully solve the traditional …

Bulk metallic glass (BMG) materials have good mechanical properties, such as hardness, and some have superior corrosion resistance. With high glass-forming ability, good castability, and good printability, bulk glassy alloys have been applied to the fields in which conventional crystalline alloys cannot be used [Inoue et al., 2008]. However, the poor ductility and formation of shear bands induced …

Introduction
   
Since the innovative discovery by Fujishima and Honda in 1972,¹ development of semiconductor photocatalyst for efficient water splitting application has been focused in many studies. Nevertheless, the wide band gap of TiO₂ limits its photocatalytic properties in the UV region. On the contract, low band gap semiconductor like CdS and CdSe, …

1.Introduction

White-emissive organic/polymer light-emitting diodes (O/PLEDs) have received considerable interest recently, because of their potential applications in back-lighting or as solid-state-lighting sources. As a decent solid-state-lighting source, the electroluminescence (EL) of O/PLEDs should include broad emissions that cover the entire visible range of the …
