1. On the Application of Surface Wave Surveys for Seismic Site Response Evaluation
Sammanfattning : In sites where earthquakes occur, the use of surface wave methods represents a convenient and effective procedure for soil characterization. In particular, Multichannel Analysis of Surface Wave (MASW) has become a popular tool in many seismic micro-zoning projects. LÄS MER
2. Optimisation of Machining Operations by means of Finite Element Method and Tailored Experiments
Sammanfattning : Traditionally, costly experimental procedures have been followed in industry to optimise the machining operations to secure the maximum efficiency in production line, while the functional requirements of the machined surfaces are fulfilled. In recent years, development of robust numerical techniques such as Finite Element Method (FEM) and advances in computing capacity of computers have made it possible to simulate the machining operations under operational conditions.

3. Optimisation of Machining Operations by means of Finite Element Method and Tailored Experiments
Sammanfattning : The experimental approach has long been the main method to investigate the responses associated with metal cutting process such as cutting forces and temperatures and also to optimise the machining operations to accomplish higher productivity. In recent years, with advances in computing power of computers along with development of robust numerical methods such as Finite Element Method (FEM), it has been possible to simulate different machining process under operational conditions.

4. Metal Particles – Hazard or Risk? Elaboration and Implementation of a Research Strategy from a Surface and Corrosion Perspective
Sammanfattning : Do metal particles (including particles of pure metals, alloys, metal oxides and compounds) pose a hazard or risk to human health? In the light of this question, this thesis summarizes results from research conducted on metal particles, and describes the elaboration and implementation of an in vitro test methodology to study metal release from particles through corrosion and dissolution processes in synthetic biological media relevant for human exposure through inhalation/ingestion and dermal contact. Bioaccessible metals are defined as the pool of released metals from particles that potentially could be made available for absorption by humans or other organisms. LÄS MER
5. On the role of surface properties for implant fixation : From finite element modeling to in vivo studies
Sammanfattning : The aim of this thesis was to gain a deeper understanding of the factors contributing to the fixation of bone-anchored implants, especially with regard to surface chemistry, surface topography and implant loading. The methodology used in the thesis ranges from systematic bench studies, computer simulations, experimental in vivo studies, to load cell measurements on patients treated with bone-anchored amputation prostheses.
