11. Atomistic simulations of lattice defects
Sammanfattning : Mechanical properties of solids are governed by crystal imperfections. Computational materials science is largely concerned with the modelling of such defects, e.g. their formation, migration, and interaction energies. LÄS MER
12. Voronoi-Based Coding
Sammanfattning : The performance of a digital communication system can generally be improved by increasing the number of variables being jointly coded. In this sense, it is desirable to have, e.g., higher-dimensional quantizers, longer channel codes, and more users in a multiple-access system. LÄS MER
13. The one-dimensional Kondo Lattice in the Majorana Fermion representation
Sammanfattning : This thesis analyses the possibilities offered by the representation of quantum mechanical operators in terms of Majorana fermions. These objects can be imagined as algebraic constituents of the fermionic degrees of freedom, allowing for a different representation of many Hamiltonians. LÄS MER
14. On some Orderings of Extensions of Arithmetic
Sammanfattning : .... LÄS MER
15. Some aspects on designing for metal Powder Bed Fusion
Sammanfattning : Additive Manufacturing (AM) using the Powder Bed Fusion (PBF) is a relatively new manufacturing method that is capable of creating shapes that was previously practically impossible to manufacture. Many think it will revolutionize how manufacturing will be done in the future. LÄS MER
