    Abstract : Wireless sensor network (WSN) has become a hot topic lately. By using WSN things that previously were difficult or impossible to measure has now become available. One of the main reasons using WSN for monitoring is to save money by cost optimization and/or increase safety by letting the user knowing the physical status of the monitored structure. READ MORE

    Abstract : The steel- and metal industry has an extensive production processing comprising many different process steps of solid, gaseous and liquid nature. Thus it is obvious that a number of different measurement technologies must be used to collect and evaluate key physical parameters which are necessary to control the production processes. READ MORE

  7. 10. Towards a microwave hyperthermia system for head and neck tumors

    Author : Pegah Takook; Chalmers tekniska högskola; []
