1. Acoustic source characterisation for non-linear in-duct sources
Abstract : Different ways to model acoustic in-duct sources have beenanalysed. Measurements were conducted on two diesel truckengines. It was found that for steady state oscillations, onecould linearise in the neighbourhood of a given linearisationpoint, i.e. READ MORE

2. Voltage Sags: Single event characterisation, system performance and source location
Abstract : This thesis deals with one of the most important disturbances that affect the quality of the electrical supply. Voltage sags cause industrial processes malfunction, producing an enormous economical impact. A voltage sag is defined as a short duration reduction of the rms voltage. READ MORE

3. Investigation of acoustic source characterisation and installation effects for small axial fans
Abstract : 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. READ MORE

4. Enhanced Biological Phosphorus Removal - Carbon Sources, Nitrate as Electron Acceptor, and Characterisation of the Sludge Community
Abstract : Enhanced biological phosphorus removal (EBPR) was studied in laboratory scale experiments as well as in a full scale EBPR process. The studies were focused on carbon source transformations, the use of nitrate as an electron acceptor and characterisation of the microflora. READ MORE
