16. Design, Modelling and Control of Electrical Machines - With Applications to Iron-powder Machines and Acoustic Noise
Abstract : This thesis consists of two parts, the first dealing with the design of iron-powder synchronous machines, and the second with the analysis and prediction of the acoustic noise in electrical machines. In Part I, a 1.6 kW electrically magnetized claw-pole machine with magnetically conducting end-plates has been analyzed and a prototype tested. READ MORE

17. Drum sound from floor coverings - objective and subjective assessment
Abstract : Drum sound is the sound produced when an object, such as a foot, hits the flooring in the room in which the receiving ear is located. Drum sound has attracted interest in recent years, particularly due to an increased use of thin floating floor constructions, such as veneer or laminate flooring, which can produce loud and sharp walking sound.

18. Articulatory-Acoustic Relationships in Swedish Vowel Sounds
Abstract : The goal of this work was to evaluate the performance of a classical method for predicting vocal tract cross-sectional areas from cross-distances, to be implemented in speaker-specific articulatory modelling. The data forming the basis of the evaluation were magnetic resonance images from the vocal tract combined with simultaneous audio and video recordings. READ MORE

19. Design foundations for content-rich acoustic interfaces : Investigating audemes as referential non-speech audio cues
Abstract : To access interactive systems, blind and visually impaired users can leverage their auditory senses by using non-speech sounds. The current structure of non-speech sounds, however, is geared toward conveying user interface operations (e.g., opening a file) rather than large theme-based information (e. READ MORE
