1. Nonlinear phonocardiographic Signal Processing
Sammanfattning : The aim of this thesis work has been to develop signal analysis methods for a computerized cardiac auscultation system, the intelligent stethoscope. In particular, the work focuses on classification and interpretation of features derived from the phonocardiographic (PCG) signal by using advanced signal processing techniques. LÄS MER
2. A Novel Oil-immersed Medium Frequency Transformer for Offshore HVDC Wind Farms
Sammanfattning : In this project, a design of an oil type medium frequency transformer for offshore wind farm applications is proposed. The design is intended for applications when series coupling of the output of the DC/DC converters of the wind turbine on their secondary side is done to achieve a cost-effective high voltage solution for collecting energy from offshore wind parks.

3. Communication and Positioning Uncertainties in Cooperative Intelligent Transportation Systems
Sammanfattning : The current road transport system has problems with both safety and efficiency. Future intelligent transportation systems (ITS) are envisioned to alleviate these problems. In particular, cooperative ITS, where vehicles are connected to each other and the cloud, will allow vehicles to collaborate and share both sensor and control information. LÄS MER
4. Data Evaluation for an Electronic Nose
Sammanfattning : An electronic nose is a device that tries to perform the same task as the human olfactory system, to be able to discriminate between different odours. In an electronic nose there are currently a number of individual sensors (typically 5-20). The response from a chemical sensor is usually measured as the change of some physical parameter, e.g. LÄS MER
5. Liquid Sensing : Development and Characterisation of an Electronic Tongue Based on Electrochemical Methods
Sammanfattning : A new sensor technology for liquid sensing is reported, i.e. the electronic tongue based on electrochemical methods. Such a system involves the combination of non-selective sensors (metal electrodes) and a signal processing part. LÄS MER
