21. The zone concept : design of low-voltage installations considering the spread of high frequency harmonics
Sammanfattning : The use of electric power has become a backbone of the modern society. Together with the growth in possible applications of electric power, we also see a growth in the number of devices and the interest of using electrical energy as an environmentally-friendly alternative to other sources of energy.

22. Washing Machine Design Optimization Based on Dynamics Modeling
Sammanfattning : The spinning process in a washing machine is a source of undesired vibrations and noise and may cause discomfort both to the user as well as for the machine itself due to vibrations which have impact on system lifetime, reliability of operation and capacity.The aim of this thesis is to develop mathematical and computational models of a washing machine of modern type and use these models for dynamics analysis and in optimization routines to make improvements of the machine mechanical design.

23. 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
24. Evaluation of Innovative Rehabilitation Technologies Utilising Polymer Composites for Aging Sewer Systems
Sammanfattning : Water and wastewater sewer system maintenance is among the costliest aspects of infrastructure investment. The replacement of deteriorated lines is a difficult and expensive process that causes community disturbance and is generally not conducted fast enough to meet demand. LÄS MER
25. Does Form follow Function? Connecting Function Modelling and Geometry Modelling for Design Space Exploration
Sammanfattning : The aerospace industry, representative of industries developing complex products, faces challenges from changes in user behaviour, legislation, environmental policy. Meeting these challenges will require the development of radically new products. LÄS MER
