Sammanfattning : The traditional energy system as we know it today will change in the future. There is a worldwide concern about the global warming situation and there are different actions implemented to limit the consequences from, mainly, the use of fossil fuels. LÄS MER
Sammanfattning : This dissertation investigates theoretically electric control of the magnetic properties of molecular magnets. Two classes of magnetic molecules are considered. The first class consists of molecules that are spin frustrated. LÄS MER
Sammanfattning : In Sweden, the change from manual meter reading at irregular intervals, to automatic remote meter reading at predefined instants was completed in July 2009. This change is ongoing or largely completed in a number of other European countries as well. Several methods for communication between the meter and the network operator are in use. LÄS MER

Power quality concerns interaction between the power grid and its customers and between the power grid and equipment connected to it, reflected in voltages and currents. LÄS MER
5. Evaluation of energy conserving measures in buildings connected to a district heating system : case studies in Gävle, Sweden
Sammanfattning : When different energy conserving measures are implemented for reducing energy use in buildings and the buildings are connected to district heating systems, it is important that an overall system analysis is made which takes into account the effects of total change of energy use due to the energy conserving measures.The method applied in this thesis uses hourly production data for the different production units in the district heating system in Gävle, Sweden.
