1. Flight strategies in migrating birds: when and how to fly
Sammanfattning : Wind has a profound influence on migrating birds since it inevitably will influence travel time and energy expenditure. In this thesis I investigate how migrating birds are affected by, and use winds. LÄS MER
2. Real-Time Optimization of Cone Crushers
Sammanfattning : Cone crushers are used in the mineral, mining, and aggregate industry for fragmentation and production of rock materials. Cone crusher control systems are widely used for machine protection, wear compensation and, to some extent, increasing production. These systems ordinarily focus on the crusher and not the yield of production process. LÄS MER
3. Friction in threaded fasteners : Influence of materials and tooling
Sammanfattning : Threaded fasteners represent the most common type of machine element, with a unique function that facilitates ease of assembly and disassembly. This ease of disassembly allows machine parts to be reused, refurbished, and recycled. LÄS MER
4. Blood pressure in very old age : determinants, adverse outcomes, and heterogeneity
Sammanfattning : Background: High blood pressure (BP) is the leading risk factor for disease and mortality worldwide. However, risks associated with high BP in very old age (≥ 80 or ≥ 85 years) are not entirely understood, as the majority of scientific studies have been performed with younger populations and existing scientific knowledge about very old individuals is sometimes contradictory.

5. Key Technologies in Low-cost Integrated Vehicle Navigation Systems
Sammanfattning : Vehicle navigation systems incorporate on-board sensors/signal receivers and provide necessary positioning and guidance information for land, marine, airborne and space vehicles. Among different navigation solutions, the Global Positioning System (GPS) and an Inertial Navigation System (INS) are two basic navigation systems. LÄS MER
