DESCRIPTION:Pollution Monitoring in the Streets of Cambridge\, Alastair Be
 resford\n\nPollution levels in Cambridge are primarily monitored by a hand
 ful of large sensors installed at fixed locations across the city. This ta
 lk will describe work undertaken as part of the MESSAGE project to explore
  the potential of mobile sensing\, with a focus on the construction\, use\
 nand some early results from the deployment of small  mobile pollution sen
 sors. The devices are sufficiently portable that they can be comfortably c
 arried by pedestrians\, cyclists and car drivers\, providing new insight i
 nto the spatio-temporal variability in pollution levels. This is a repeat 
 of a talk given by Rod Jones and Alastair Beresford in November at the Chr
 ists' College Transport Event.\n\n\n\nAn Application-Oriented Node Placeme
 nt for Wireless Sensor Networks\, Ruoshui Lui\n\nWireless Sensor Networks 
 (WSNs) provide a promising infrastructure for gathering information about 
 parameters of the physical world in various civilian applications\, such a
 s building automation\, environmental monitoring\, industrial control\, et
 c. Sensor node placement is the fundamental factor in determining the cove
 rage\, connectivity\, cost and lifetime of the networks. In this talk\, th
 e problem of optimal placement of relay nodes in the actual confined areas
 \, e.g.\, underground railway tunnel\, is tackled from a different perspec
 tive. We model the problem using the constraints which are relatively clos
 e to the actual deployment\, and we aim to develop a practical planning to
 ol for WSNs.\n
