1. Mechanical performance of NCF composites
Sammanfattning : Composite materials are today in widespread use in the aerospace and marine industries due to their excellent strength and stiffness to weight ratio. In most marine and aerospace applications traditional composites (pre- impregnated tapes) are still the main choice for design of load bearing structures. LÄS MER
2. Multi-scale analysis of mechanical phenomena in NCF composites
Sammanfattning : Mechanical phenomenon in Non Crimp Composites is studied in this thesis using a multiscale approach. This approach is choosen due to the architecture of the composite which is heterogenic both on micro as well as mesoscale. LÄS MER
3. Impacts on sewer performance due to changes to inputs in domestic wastewater
Sammanfattning : The impacts of changes in domestic wastewater inputs on sewer performance have been debated since the dawn of the great sewer construction movement in the 1850s. Nowadays, typical household wastewater that enters sewers can generally be divided into streams from the WC, shower and/or bathtub, kitchen sink, washing machine and dishwasher. LÄS MER
4. High accuracy low-cost NDIR sensing
Sammanfattning : Sensing gas concentrations using optical absorption offers valuable advantages over other methods ina wide variety of real-world applications from industrial processes to environmental change. One of the most rapidly developing detection techniques on the global market is the non-dispersive infrared method (NDIR). LÄS MER
5. Aspects of Static Multi-Class Traffic equilibria under Congestion Pricing
Sammanfattning : Congestion charging is a now accepted means of influencing traffic to behave in a more socio-economic optimal way, like e.g. in the Stockholm project. Already early work, in the 1920’s, showed that road use can be inefficient due externalities, i. LÄS MER
