1. Design of a grating lobe mitigated antenna array architecture integrated with low loss PCB filtering structures
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. LÄS MER
2. Electrodynamic field at spatial infinity
Master-uppsats, KTH/FysikSammanfattning : The treatment of spatial infinity is one of the remaining major open problems in the theory of isolated self-gravitating systems. Especially when one wants to model scattering of gravitational radiation in spacetime. In this thesis the conformal theory is used to study simple electromagnetic fields, close to spatial infinity.

3. A Case Study of the Swedish Steel Company SSAB AB and the Contributing Factors to its Commitment to Green Transition
Master-uppsats, Stockholms universitet/Institutionen för ekonomisk historia och internationella relationerSammanfattning : This paper analyzes Swedish steel company’s SSAB commitment to the green transition focusing on how and why aspects. The how part of this problem relates to topical conjunctures, which emerge independently of a company. LÄS MER
4. Lucas and Penrose vs. Computationalism: A Refutation of the Gödel-arguments
Kandidat-uppsats, Lunds universitet/Teoretisk filosofiSammanfattning : John Lucas and Roger Penrose attempted to refute Computationalism, the theory that the human mind is a computational system. They did so by utilizing meta-mathematical proofs by Kurt Gödel. LÄS MER
5. Spherically Symmetric Gravitational Collapse
Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationSammanfattning : This thesis presents a derivation of the equation of motion of particles in a dust star, as it undergoes collapse. This is done by finding exact solutions to the Einstein field equations. We follow the original work by Oppenheimer and Snyder, starting from the general spherically symmetric metric in comoving coordinates. LÄS MER
