Abstract

Skills: Analog Electronics, Anthony Hylick

This skills talk will introduce some elementary RC components and circuits and demonstrate how some very simple circuits can be very useful in a few different applications. The talk will cover basic RC device characteristics (and a little on bipolar junction transistors), three live demos, and detailed explanations of why the circuits behave as they do in the demos.

Research: Deployment of Wireless Sensor Networks, Ruoshui Liu

Wireless Sensor Networks (WSNs) provide a new paradigm for sensing and disseminating information from various physical environments, with the potential to serve many and diverse applications. Successful deployment of WSNs in real environments requires a comprehensive knowledge of the radio channel characteristics within these environments, since the channel has a significant impact on the coverage range and quality of the radio links between nodes. The research investigates the use of frequency and space (antenna) diversity techniques applied to WSNs to ameliorate the impact of the wireless channel on the communication link and improve the robustness of the radio links.
