  1. 1. The Impact of Swampland Conjectures

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Daniel Nilsson; [2023]
    Keywords : String theory; Quantum gravity; Swampland program; Effective field theories;

    Abstract : The Swampland program is way of sorting effective field theories based on conjectures of how an effective field theory consistent with quantum gravity should look like. In this thesis we take a closer look at the No Global Symmetries Conjecture, the Weak Gravity Conjecture, the de Sitter Conjecture and the Trans-Planckian Censorship Conjecture. READ MORE

  3. 2. Educational superintendents' perspectives of a national networking project on school segregation in Sweden : Lessons to be learned?

    University essay from Stockholms universitet/Institutionen för pedagogik och didaktik

    Author : Daniel Nilsson Brodén; [2023]
    Keywords : Superintendent; school superintendent; school segregation; educational leadership; educational equity; professional development; governance; networks;

    Abstract : World-wide, countries struggle with providing equitable education to all children, where the socioeconomic (SES) background of the students does not affect their educational attainment and achievement. School segregation has been shown in previous research to exacerbate the influence of family background on educational achievement and attainment. READ MORE

  4. 3. Optimizing databases in the cloud based on performance and cost savings

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Felix Nilsson; Daniel Mihajlovic; [2022]
    Keywords : Resource provisioning; Cloud service platform; Optimizing cost; Database; Performance; Metrics; Technology and Engineering;

    Abstract : As cloud service providers becomes more prevalent, so does questions related to cost efficiency of hosted resources. Payment models for cloud hosted resources tend to be either subscription based or pay-as-you-go for computing resources, in this case for compound metrics of CPU, Data IO and Log IO. READ MORE

  5. 4. Calculating scattering amplitudes in φ3 and Yang-mills theory using perturbiner methods

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Daniel Nilsson; Magnus Bertilsson; [2022]
    Keywords : QFT; Quantum; Quantum field theory; scattering amplitudes; Berends Giele Currents; feynman diagrams; n particle scattering;

    Abstract : We calculate tree-level scattering amplitudes in φ^3 theory and Yang-Mills theory by means of the perturbiner expansion. This involves solving the Euler-Lagrange equations of motion perturbatively via a multi-particle ansatz, and using Berends-Giele recursion relations to extract the solution from simple on-shell data.

  6. 5. Identifying Bluetooth Low Energy Devices via Physical-Layer Hardware Impairments

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Daniel Nilsson; [2022]
    Keywords : ;

    Abstract : It is desirable to be able to distinguish between Bluetooth Low Energy (BLE) devices purely based on individual hardware imperfections because such imperfections are often prohibitly expensive to imitate. Other works have been done on this topic in the past, which utilized signal transients requiring a multi-GHz sampling rate recorded with costly special equipment to be satisfactorily captured.
