16. Structure-acoustic analysis; finite element modelling and reduction methods
Sammanfattning : 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. LÄS MER
17. In-vehicle speed adaptation - On the effectiveness of a voluntary system
Sammanfattning : The overarching aim of this thesis is to study the long term effects of a voluntary speed adaptation system, the Active Accelerator Pedal (AAP), and its effectiveness for different driver types. The papers making up this thesis are based on a study carried out on 284 vehicles and drivers in the Swedish city of Lund from 1999 until 2002. LÄS MER
18. Interpreting budget deficits and productivity fluctuations
Sammanfattning : This thesis includes four self-contained essays on budget deficits and productivity fluctuations:ESSAY I evaluates the effects of budget deficits on several key macroeconomic variables of the Swedish economy by estimating a vector autoregression model. The main finding is that - apart from a positive transitory real interest rate effect associated with a shock in the deficit - neither actual nor unexpected movements in deficits have any significant explanatory power for the determination of real non-fiscal variables.

19. Tree Models for Design Space Exploration in Aerospace Engineering
Sammanfattning : A crucial issue in the design of aircraft components is the evaluation of a larger number of potential design alternatives. This evaluation involves too expensive procedures, consequently, it slows down the search for optimal design samples. LÄS MER
20. Exploring Massively Parallel Models and Architectures for Efficient Computation of Evolutionary Algorithms
Sammanfattning : 'Evolutionary algorithms' is the collective name for a group of relatively new stochastic search algorithms that have several unique and interesting properties. However, as with all search algorithms, evolutionary algorithms also have disadvantages. LÄS MER
