1. Multichannel Audio Signal Processing : Room Correction and Sound Perception
Abstract : This thesis concerns and combines multichannel sound reproduction, digital room correction, audio signal processing, and human sound perception. It investigates perceived sound quality and new methods to improve timbral and spatial fidelity of loudspeaker-based multichannel sound reproduction in reverberant environments. READ MORE

2. Wearable systems and sensors for the assessment of motor control : Development and validation of methods for clinical assessment of idiopathic normal pressure hydrocephalus
Abstract : Human gait and balance are controlled by automatic processes in the central nervous system, and in sensory and proprioceptive systems. If a disturbance occurs in any of these complex structures, it may lead to balance and gait problems. READ MORE

3. Assessment and control of tonal components in electric vehicles
Abstract : New challenges arise for noise, vibration and harshness (NVH) engineers when electric motors are introduced into cars traditionally powered by internal combustion engines (ICE). The noise signature from an electric traction motor is characterized by speed-dependent high frequency tonal components due to electro-magnetic excitation. READ MORE

4. Predictive model of perceived driving stability at high speeds under aerodynamic excitations
Abstract : The automotive industry is continuously advancing towards more energy-efficient vehicle designs. Streamlined vehicles have low aerodynamic drag but have the potential to be unstable when exposed to external excitations such as unsteady aerodynamic forces created by the flow of air around them.

5. Laparoscopic or Open Antireflux Surgery - A Comparative Study with Special Reference to the Patient´s Perspective
Abstract : The overall aim of this thesis was to compare the effects of laparoscopic versus open antireflux surgery in a randomized clinical trial focusing the patients' subjective and objective outcome postoperatively, from a short-term and a long-term perspective. A further aim was to describe GORD patients' experiences of illness and surgical treatment and if possible to find striking characteristics relating to laparoscopic or open surgery. READ MORE
