This paper is composed of a survey on wearable computers and a research agenda to further pursue topics in the communication area. We begin with a brief walk-through of the terminology and examples, followed by motivation originated from two historical trends – enhancing human biological ability and increasing resource accessibility. Then, we investigate the existing technologies and relevant r...

Application of quantum-dot is a promising technology for implementing digital systems at nano-scale.  Quantum-dot Cellular Automata (QCA) is a system with low power consumption and a potentially high density and regularity. Also, QCA supports the new devices with nanotechnology architecture. This technique works </...
