6. Högpresterande betongs hydratation, struktur och hållfasthet
Sammanfattning : Syftet med projektet var att jämföra egenskaper hos s k högpresterande betong, d v s betong med mycket låga vattenbindetal (vbt) med motsvarande egenskaper hos normala betongkvaliteter. Studerade egenskaper är hydration, hållfasthetstillväxt och fukttransportegenskaper. LÄS MER
7. Power System Damping - Structural Aspects of Controlling Active Power
Sammanfattning : Environmental and economical aspects make it difficult to build new power lines and to reinforce existing ones. The continued growth in demand for electric power must therefore to a great extent be met by increased loading of available lines. LÄS MER
8. Increased resilience in managed boreal forests : Controlling damage by spruce bark beetle and moose in Sweden
Sammanfattning : Most of the forests growing in Europe today have been planted, or heavily affected, by humans. This is because the forest industry provides crucial raw materials for diverse products, including timber, pulp and paper, cellulose-based substances and renewable energy sources. LÄS MER
9. Solute transport in fractured rocks : Analysis of analytical solutions and determination of transport parameters
Sammanfattning : In order to facilitate the assessment of the safety and function of deep geological repositories for radioactive waste, several models have been developed to describe water flow and transport of solutes in fractured crystalline rock. The rock around the repository is described and modelled as a network of water-bearing fractures. LÄS MER
10. On the Performance of Long-Range Autonomous Underwater Vehicles : Enhancing the Endurance of AUVs
Sammanfattning : Autonomous underwater vehicles (AUVs) are robotic platforms that are commonly used to gather environmental data, provide bathymetric images, and perform manipulation tasks. These robots are used not only for scientific, but also for industrial and military purposes. LÄS MER
