1. Design and Packaging of All-in-One Axle
University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesignAbstract : The aim of this thesis work is to design an electric axle that contains all the operational components, like the powertrain, suspension, brakes, and steering system. One of the requirements of this design work is to package all the axle components compactly in one single unit. READ MORE

2. Integrability and Thermodynamics of the Gross-Neveu Model
University essay from KTH/FysikAbstract : The Gross-Neveu model is a quantum field theory of interacting N-flavor fermions in 1+1dimensions, with interaction term $(\bar{\psi}_f\psi_f )^2$. This model is studied using the property offactorized scattering. READ MORE

3. Methods from Linear Algebra for the Enumeration of Spanning Trees
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : In this report, we study the enumeration of spanning trees in graphs, using two methods withinlinear algebra, Kirchhoff’s Matrix Tree Theorem and an alternative method, also referred to asLemma 1, derived by S. Klee and M.T Stamps in [KS20]. READ MORE

4. Development of Elastic Mechanism for actuation of Valve
University essay from KTH/MaskinkonstruktionAbstract : The HGR valve, or hot gas recirculation valve, is an essential component of modern internal combustion engines. Its main function is to reduce emissions of nitrous oxide (NOx), which is a harmful pollutant produced during combustion. READ MORE

5. Scattering of Charge Carriers in 2+1-Dimensional Quantum Field Theory
University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Abstract : The aim of this thesis is to examine the hard $S$-matrix for QED and QCD, due to Hannesdottir and Schwartz [1], both recreating known results, and finding new results in lower dimensions. Electrons by themselves are not gauge invariant, and in the massless limit do not give finite $S$-matrix elements for individual processes; one needs to add together seemingly arbitrary combinations of diagrams in order to be able to calculate the scattering cross-section.
