6. Contact stiffness in tyre/road noise modelling and speed dependencies of tyre/road noise generation mechanisms
Sammanfattning : Tools for simulating tyre/road noise are highly valuable in the efforts to limit the negative consequences of road traffic noise.A numerical tyre/road noise simulation tool was in this study used to investigate how the contact stiffness parameter affects the predicted tyre/road noise.

7. Application of Automated Non-contact Resonance Testing for Low Temperature Behavior of Asphalt Concrete
Sammanfattning : Impact resonance testing is a well-documented non-destructive testing method and its applications on asphalt concrete have also been implemented successfully. The test is carried out manually by inducing an impact in order to excite the test specimen and taking measurements of the vibrational response. LÄS MER
8. Beam-to-Beam Contact and Its Application to Micromechanical Simulation of Fiber Networks
Sammanfattning : This doctoral thesis covers the topic of modeling the three-dimensional fiber net- works with the finite element method. It contains the part addressing the numerical aspects of the modeling, namely, the contact formulation and application of the developed methods to the fundamental questions such as the effect of randomness in fiber properties and effect of fines and hygroexpansion.

9. Tactile sensing of prostate cancer : a resonance sensor method evaluated using human prostate tissue in vitro
Sammanfattning : Prostate cancer is the most frequent type of cancer in men in Europe and the USA. The methods presently used to detect and diagnose prostate cancer are inexact, and new techniques are needed. LÄS MER
10. Charged Polymers at Spherical Surfaces
Sammanfattning : Two separate topics in the area of colloidal chemistry have been investigated by the use of molecular modeling: the structural properties of polyion?macroion complexes and of diblock polyampholyte brushes. The main results were obtained by the use of Monte Carlo simulation in the framework of the primitive model, and in the case of polyampholyte brushes the simulation results were also complemented by lattice mean-field calculations.
