11. Quantum Transport Theory in Graphene
Abstract : In this thesis, we focus on different aspects of electron transport in nanostructured graphene (such as graphene nanoribbons). Wedevelop and implement numerical methods to study quantum coherent electron transport on an atomistic level, complemented by analytical calculations based on the Dirac approximation valid close to the points $\vec{K}$ and $\vec{K}^\prime$ in the graphene Brillouin zone.

12. Road Safety Development Index : Theory, Philosophy and Practice
Abstract : This dissertation develops, presents and tests a new international tool, the so-called Road Safety Development Index (RSDI), which indicates in a comprehensive and easy way the severity of the road safety situation in a specific country and/or in comparison with other countries. There are three pillars of outcomes involved in the framework of RSDI. READ MORE

13. Purchasing process for freight transport services and influence on CO2 emissions
Abstract : Companies purchasing freight transport services may through the purchasing process restrict or create opportunities for how transport service providers deliver the transport service. The purpose of this thesis is to explore how the configuration of the purchasing process for freight transport services can influence the reduction of CO2 emissions. READ MORE

14. Turbulent impurity transport in tokamak fusion plasmas
Abstract : With the enormous growth of high performance computing (HPC) over the last few decades, plasma physicists have gained access to a valuable instrument for investigating turbulent plasma behaviour. In this thesis, these tools are utilised for the study of particle transport in fusion devices of the tokamak variety, focusing in particular on the transport of impurities. READ MORE

15. Maturation of Clay Seals in Deep Bore Holes for Disposal of Radioactive waste : Theory and Experiments
Abstract : KBS-3 and very deep borehole (VDH) concepts are two major types of long-term geologicaldisposal methods for high-level radioactive waste (HLW) isolating from the biosphere. TheKBS-3V concept for isolating the HLW at the depth of 400-500 m, is the officially proposedoption in Sweden and has been the subject of considerable research in the past few decades,while the VDH concept was considered as an option in the 1950s but later became discouragedbecause of insufficient experience in drilling technology.
