Personalized Rough-Set-based Recommendation by Integrating Multiple Contents and Collaborative Information
Vincent S. Tseng

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 …

INVESTIGATION OF THE RELATIONSHIP BETWEEN PRIMARY AND SECONDARY SHEAR BANDS INDUCED BY INDENTATION IN BULK METALLIC GLASSES
Jen-Fin Lin

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 …

Heat Annealing Effect on the Performance of CdS/CdSe Sensitized TiO2 Photoelectrodes in Photochemical Hydrogen Generation
Yuh-Lang Lee

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, …

White-emissive tandem-type hybrid organic/polymer diodes with (0.33, 0.33) chromaticity coordinates
Tzung-Fang Guo

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 …
