16. Structure-acoustic analysis; finite element modelling and reduction methods
Abstract : This thesis investigates structure-acoustic systems by use of finite element analysis. The systems studied here are limited to those that consist of an enclosed acoustic fluid cavity, which is coupled to a flexible structure and/or a porous sound absorbing material domain. READ MORE

17. Vibration transmission in lightweight buildings : Numerical prediction models
Abstract : Ljud från grannar är ett återkommande problem för boende i flerfamiljshus. Problemen är generellt mer omfattande för de som bor i flervåningshus byggda i trä, en byggnadstyp som blir allt vanligare i Sverige. Många av de boende i trähus upplever även att störande vibrationer är vanligt förekommande i trähus. READ MORE

18. Vibrations in lightweight structures - Efficiency and reduction of numerical models
Abstract : Multi-storey wood buildings have been increasing in popularity since a century-old ban on the construction of such buildings was lifted in 1994. Compared to conventional concrete structures, it is more difficult to build lightweight structures in such a way that noise and disturbing vibrations is avoided. READ MORE

19. Digital product catalogues : an evaluation of presentation and visualization techniques
Abstract : This licentiate thesis concerns advanced digital product catalogues, with the main focus on product presentation. A computer based digital product catalogue opens new possibilities for advanced product presentation and integration into the existing compute environment. Several new possibilities for product presentation become available. READ MORE

20. Methods for Aircraft Noise and Vibration Analysis
Abstract : Aircraft noise control engineering is a challange both for experimentally based methods and for numerical analysis methods. Usually noise control installations are designed based on engineering judgement in combination with results from in-flight testing, rather than with nummerical methods, due to the absence of reliable and accurate models.
