Respiratory monitoring with an acceleration sensor

Physics in Medicine and Biology, 2011
Respiratory gating radiotherapy is used to irradiate a local area and to reduce normal tissue toxicity. There are certain methods for the detection of tumor motions, for example, using internal markers or an external respiration signal. However, because some of these respiratory monitoring systems require special or expensive equipment, respiratory ...

Accelerating Initialization for Sensor Networks

GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009
Initialization is an indispensable process for wireless sensor networks since newly deployed sensors lack a reliable infrastructure for communication. Many efforts have been made to address the problem on initialization. However, most of them fall into the category of energy efficiency.
