11. Biomechanical Analysis of Stress and Stiffness of New Load-Bearing Implants
Sammanfattning : Medical implants are essential products for saving lives and improving life quality. Nowadays, the demand for implants, especially biocompatible and personalized ones, is increasing rapidly to deal with factors like congenital malformations, aging, and increasing prevalence of cancer.

12. Investigation and calibration of pulsed time-of-flight terrestrial laser scanners
Sammanfattning : This thesis has two aims. The first one is the investigation and analysis of the errors occurring in the measurements with pulsed time-of-flight (TOF) terrestrial laser scanners (TLS). A good understanding of the error sources and the relationships between them is necessary to secure the data accuracy. LÄS MER
13. Applications of Ion Beam Methods in Silicide/Si and Silicide/GaAs Nanometre Structures
Sammanfattning : Ion beam methods are used to analyse material (Ion Beam Analysis, IBA) and to modify the target (Ion Beam Modification of Materials, IBMM). In this thesis, ion beams have been used in various IBA techniques to investigate the surface nanometre structures, and also in an ion beam synthesis (IBS) technique to form thin films and to modify material properties.

14. Beam Modelling for Treatment Planning of Scanned Proton Beams
Sammanfattning : Scanned proton beams offer the possibility to take full advantage of the dose deposition properties of proton beams, i.e. the limited range and sharp peak at the end of the range, the Bragg peak. LÄS MER
15. Ion beam etching of InP based materials
Sammanfattning : Dry etching is an important technique for pattern transferin fabrication of most opto-electronic devices, since it canprovide good control of both structure size and shape even on asub-micron scale. Unfortunately, this process step may causedamage to the material which is detrimental to deviceperformance. LÄS MER
