This paper proposes a mobile augmented reality system that can model 3D virtual objects and author augmented reality contents on site. The differences of the proposed system from the existing ones are an interaction approaches used to generate and manipulate primitives and additional features such as a shadow and a multi-freezing mode to create realistic(More)
Phosphorescent organic light-emitting diodes (PHOLEDs) have shown a heterojunction system that is a bulk heterojunctioned emitting layer (EML). In our work, we have demonstrated an improvement in efficiency with a partial mixed host system in an EML. A mixed host system, which is mixed with a host material and an electron transporting material, was used on(More)
