1. Time-resolved x-ray diffraction study of longitudinal optical phonons in zincblende semiconductors
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : Anharmonic decay of longitudinal optical (LO) phonons in zincblende semiconductors is not at present well characterized due to the polar and many-body nature of the problem. Femtosecond THz radiation offers a novel route to this study, as the interaction of this radiation is directly with the phonon lattice and these THz excited phonons do not have enough energy to excite electrons over the band gap.

2. Glued connection for TCC slabs : Experimental and Numerical investigation
University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)Abstract : Timber-concrete composite (TCC) structures are becoming more popular in several industrial applications as an efficient method for optimizing the structural performance and the cost of construction as well as lowering the emissions of carbon dioxide. TCC floors are more sustainable than pure concrete floors and more resistant to vibrations and excessive deflections than pure wooden floors. READ MORE

4. Accelerating longitudinal spinfluctuation theory for iron at high temperature using a machine learning method
University essay from Linköpings universitet/Teoretisk FysikAbstract : In the development of materials, the understanding of their properties is crucial. For magnetic materials, magnetism is an apparent property that needs to be accounted for. There are multiple factors explaining the phenomenon of magnetism, one being the effect of vibrations of the atoms on longitudinal spin fluctuations. READ MORE

5. A 3D sliding bearing finite element based on the Bouc-Wen model : Implementation in Abaqus
University essay from KTH/Bro- och stålbyggnadAbstract : As rail transportation is significantly more virtuous than airplanes or cars in terms of greenhousegases emissions, its development is being encouraged in several European countries, includingSweden. In addition, the development of railway lines on which trains can travel at higher speeds ismade in Sweden with the integration of existing infrastructure. READ MORE
