6. Centralized Routing for Prolonged Network Lifetime in Wireless Sensor Networks
Sammanfattning : In this thesis centralized routing methods for wireless sensor networks have been studied. The aim has been to prolong network lifetime by reducing the energy consumed by sensor-node communication.Wireless sensor networks are rapidly becoming common in application areas where information from many sensors is to be collected and acted upon.

7. Sensitivity and selectivity studies in capillary electrophoresis
Sammanfattning : Capillary electrophoresis is characterised by high separation efficiency, applicability to a wide range of compounds, small sample and solvent consumption and simple instrumentation. To improve sensitivity using on-line absorbance detectors, which are hampered by the short optical path length, sample volumes in the microlitre range were concentrated to nanolitre volumes either off-line or on-line.
