11. Utveckling av arbetsmiljö och upplevd hälsa : en longitudinell undersökning av anställda i kraftindustrin
Sammanfattning : I avhandlingen undersöks hur arbetsmiljön påverkar den upplevda hälsoutvecklingen över en nioårsperiod hos 440 elarbetare inom kraftindustrin. Problemet beskrivs utifrån en teoretisk modell över orsakssamband mellan arbetsmiljö och upplevd ohälsa. En ytterligare målsättning är att jämföra data av olika subjektivitetsgrad. LÄS MER
12. On high-frequency distortion in low-voltage power systems
Sammanfattning : Power quality is a subject that has received a lot of attention during the last 10 to 20 years, both in industry and in academia. 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
13. Robotized Production Methods for Special Electric Machines
Sammanfattning : A research project on renewable energy conversion from ocean waves to electricity was started at the Division of Electricity at Uppsala University (UU) in 2001. The Wave Energy Converter (WEC) unit developed in this project is intended to be used in large offshore WEC farms and has therefore been designed with large-scale production in mind. LÄS MER
14. High frequency distortion in power grids due to electronic equipment
Sammanfattning : Power quality is a subject that has received a lot of attention during the last 10 to 20 years, both in industry and in academia. 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
15. Towards Low-Voltage, High-Current : A pioneering drive concept for battery electric vehicles
Sammanfattning : The first electric low-voltage vehicles were constructed in the mid-19th century, but by the early 20th century they were progressively replacedby successors with internal combustion engines. As the consequences ofusing fossil fuels are better understood, our society is now transitioning back. LÄS MER
