21. Data Assimilation in Fluid Dynamics using Adjoint Optimization
Abstract : Data assimilation arises in a vast array of different topics: traditionally in meteorological and oceanographic modelling, wind tunnel or water tunnel experiments and recently from biomedical engineering. Data assimilation is a process for combine measured or observed data with a mathematical model, to obtain estimates of the expected data. READ MORE

22. Measuring degradation in cable insulation material under realistic operation conditions
Abstract : One of the challenges in laboratory investigation of degradation and ageing of HVDC cable insulation is related to securing, or in other words, imitating the real service environment of the material specimens. So far, the published data refer to experiments conducted in thermo-oxidative conditions, which is not the case during normal cable operation. READ MORE

23. Large eddy simulation of dual-fuel combustion under ICE conditions
Abstract : The present thesis aims at studying n-heptane/methanol dual-fuel combustion under internal combustion engine conditions and strives to improve the understanding of its ignition, combustion, and pollutant emission mechanisms. Large-eddy simulation (LES) coupled with Eulerian stochastic fields (ESF) approach is employed to simulate single/dual-fuel combustion in a constant-volume vessel to mimic the single/dual-fuel combustion in conventional/dual-fuel premixed engines.

24. Environmental Actions and Response - Reinforced Concrete Structures exposed in Road and Marine Environments
Abstract : The expenses for repair, maintenance and remediation of existing concrete structures have significantly increased. A large proportion of these expenses are due to problems related to a lacking durability of the structure. READ MORE

25. Improving initial care of road traffic injured people in Tanzania : Evaluation of a traffic police first aid education programme
Abstract : Background: An overwhelming proportion of road traffic deaths and injuries in low- and middle-income countries occurs in prehospital environments. Lay responders such as traffic police officers play an important role in providing initial assistance to victims of road crashes, either alone or in collaboration with others. READ MORE
