16. Surface integrity on post processed alloy 718 after nonconventional machining
Sammanfattning : There is a strong industrial driving force to find alternative production technologies in order to make the production of aero engine components of superalloys even more efficient than it is today. Introducing new and nonconventional machining technologies allows taking a giant leap to increase the material removal rate and thereby drastically increase the productivity. LÄS MER
17. Approximations and abstractions for reasoning about machine arithmetic
Sammanfattning : Safety-critical systems rely on various forms of machine arithmetic to perform their tasks: integer arithmetic, fixed-point arithmetic or floating-point arithmetic. The problem with machine arithmetic is that it can exhibit subtle differences in behavior compared to the ideal mathematical arithmetic, due to fixed-size representation in memory. LÄS MER
18. Towards understanding breakage and flow in sublevel caving (SLC) : Development of new measurement techniques and results from full-scale tests
Sammanfattning : Blast function, fragmentation and gravity flow are core elements for sublevel caving (SLC). For the ore recovery to be as high and the waste rock dilution as low as possible all three elements have to work as planned. LÄS MER
19. Rock damage caused by underground excavation and meteorite impacts
Sammanfattning : The intent of this thesis is to contribute to the understanding of the origin of fractures in rock. The man-made fracturing from engineering activities in crystalline rock as well as the fracturing induced by the natural process of meteorite impacts is studied by means of various characterization methods.

20. Cellular responses to titanium surfaces blasted with TiO2 particles
Sammanfattning : A major determinant of successful osseointegration of endosseous implants is the surface topography of the implant, which influences the cellular response of the surrounding tissues. This series of experimental studies investigated cellular responses to surface modifications of titanium implant material. LÄS MER
