1. Falls in people with dementia
Sammanfattning : Falls and concomitant injuries are common problems among large groups of the elderly population, leading to immobility and mortality. These problems are even more pronounced among people suffering from dementia. This thesis targets fall risk factors for people with dementia in institutions. LÄS MER
2. Resonant Tunneling in Laterally Confined Quantum Structures
Sammanfattning : In the thesis, three-dimensionally confined resonant tunneling structures were studied experimentally. Two approaches were used for obtaining quantum confinement: gate-defined lateral constriction of double barrier structures, and epitaxial growth of self-assembled quantum dots. LÄS MER
3. On the role of terrestrial ecosystems in a changing Arctic
Sammanfattning : The global temperature rise is proportional to the cumulative amount of CO2 emissions to the atmosphere. This observation is consistent between climate models and historical observations. LÄS MER
4. Automation of Load Haul Dump machines : comparative performance analysis and maintenance modeling
Sammanfattning : The Load Haul Dump (LHD) machine and its operating environment create a complex system. Mine productivity depends on the operation of the LHDs and on the mining environment, including fragmentation, size of boulders, navigation techniques etc. Traditional navigation techniques require a lot of infrastructure to accommodate automatic operation.

5. Dependability assurance for automatic load haul dump machines
Sammanfattning : Load Haul Dump (LHD) machines are used in underground mines to load and transport ore and minerals. Loading and hauling blasted ore from drawpoint to dumping point constitute a significant portion of the production costs for mining companies. LÄS MER
