  1. Instruments Sensors and the Semantic Grid David De Roure

  2. Semantic Pervasive Grid

  3. Machine-processable Descriptions for interop and automation Grid and Pervasive share issues in large scale distributed systems. e.g. service description, discovery, composition; autonomic computing. These can be aided with semantics. Pervasive applications need the Grid, e.g. Sensor Networks Grid applications need Pervasive Computing e.g. Smart Laboratory Scientific Instruments and Sensors on the Grid

  4. Outline • Pervasive Grid FloodNet, Medical Devices • Semantic Grid myGrid, CoAKTinG • Semantic Pervasive Chawton House • Pervasive Semantic Grid CombeChem • Reflections S 2 3 4 P G 1 Scientific Instruments and Sensors on the Grid
