1. Tensor rank and support rank in the context of algebraic complexity theory
Master-uppsats, KTH/Matematik (Avd.)Sammanfattning : Starting with the work of Volker Strassen, algorithms for matrix multiplication have been developed which are time complexity-wise more efficient than the standard algorithm from the definition of multiplication. The general method of the developments has been viewing the bilinear mapping that matrix multiplication is as a three-dimensional tensor, where there is an exact correspondence between time complexity of the multiplication algorithm and tensor rank.

2. Pattern Mining in Uncertain Tensors
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Data mining is the art of extracting information from data and creating useful knowledge. Itemset mining, or pattern mining, is an important subfield that consists in finding relevant patterns in datasets. LÄS MER
3. Simple cosmological models and their descriptions of the universe
Kandidat-uppsats, Linköpings universitet/Matematik och tillämpad matematikSammanfattning : Cosmology is the study of the universe as a whole, and attempts to describe the behaviour of the universe mathematically. The simplest relativistic cosmological models are derived from Einstein's field equations with the assumptions of isotropy and homogeneity. LÄS MER

5. Experimental and Numerical Investigation of Ratcheting Effects in 316L Stainless Steel - The Two-Rod approach.
Magister-uppsats, KTH/Hållfasthetslära (Inst.)Sammanfattning : This Master’s Thesis was conducted during spring 2014. An experimental and numerical investigation was conducted on the austenitic 316L stainless steel. The main focus of the study was the investigation of ratcheting effects. Experimentally, the main focus was the two-rod test, which had not been conducted previously. LÄS MER
