21. Investigation of acoustic source characterisation and installation effects for small axial fans
Sammanfattning : Fans are often used in equipment such as home appliances andelectronic equipment where the margin of profit is small butcustomers demands on a low noise level are high. Therefore,methods for predicting the noise emitted by an applicationincluding one or several fans are desirable in order toimprove, accelerate and reduce the cost of low-noise design. LÄS MER

23. An experimental and numerical study of an automotive cooling module
Sammanfattning : Heavy vehicles are major emitters of noise. Especially at idle or low vehicle speeds a large portion of the noise emanates from the fan that forces the flow through the cooling module. The aim of this work is to investigate and reveal aerodynamic and acoustic installation effects linked to the cooling package. LÄS MER
24. Renewable energy and the function of law : a comparative study of legal rules related to the planning, location and installation of windmills
Sammanfattning : Swedish energy policy relies heavily on the promotion of renewable energy, in particu-lar wind power. Notwithstanding a substantial political and economic support for this development, the installed capacity of wind power in Sweden remains fairly small both in relation to the corresponding development in other countries and in absolute num-bers.

25. Simulation of lightning electromagnetic fields and their interaction with low voltage power installations : By Arturo Galván Diego
Sammanfattning : An increasing number of damages of electric nature are being observed on modem electronic sensitiveequipment connected to low voltage power installation (LVPI) networks when they are exposed tolightning electromagnetic fields (LEMPs), or indeed, any other electromagnetic pulse (EMP). The wayin which these fields affect the electronic equipment depends on the properties of the interferencesource, the electromagnetic interaction and the hardness of the device. LÄS MER
