In recent years, Wireless Sensor Networks (WSNs) research has undergone a quiet revolution, providing a new paradigm for sensing and disseminating information from various environments. In reality, the wireless propagation channel in many harsh environments has a significant impact on the coverage range and quality of the radio links between the wireless nodes (motes). Therefore, the use of div...

This paper proposes an improved context-aware language supported system for learning Japanese mimetic words and onomatopoeia (MIO) using wireless sensor network “MOTE”. In our previous work, a learner wears sensors so that the system provides the appropriate MIO expressions at his/her place. In this current system called JAMIOLAS (Supporting Japanese Mimetic words and Onomatopoeia Learning with...

Abstract Developing selective and coherent polymorphic crystals at the nanoscale offers a novel strategy for designing integrated architectures photonic optoelectronic applications such as metasurfaces, optical gratings, photodetectors, image sensors. Here, direct writing approach is demonstrated to deterministically create 2D materials by locally inducing metallic 1T′‐MoTe 2 on semiconducting ...

Wireless Sensor Networks (WSNs) are susceptible to a wide range of malicious attacks, which has stimulated a body of research on “light-weight” security protocols and cryptographic primitives that are suitable for resource-restricted sensor nodes. In this paper we introduce MoTE-ECC, a highly optimized yet scalable ECC library for Memsic’s MICAz motes and other sensor nodes equipped with an 8-b...

In the era of internet, virtual collaboration for presentation, lectures or discussion, through Microsoft Meeting, VNC, or virtual whiteboard are common forms of communication in research and industry. Most of these present technologies focus on 2D virtual environment depicting a chalk-and-board classroom. However with the advent of 3-D visualization techniques, and gesture recognition methods,...
