  1. 21. Multi-spectral X-ray imaging with a laser-plasma accelerator

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Andrea Angella; [2022]
    Keywords : Multi-spectral imaging; single-photon counting; X-ray absorption spectroscopy; XAS; LWFA; laser-wakefield acceleration; K-edge; imaging; metal-detection algorithm; Physics and Astronomy;

    Abstract : This master thesis focuses on the creation of an algorithm to perform multispectral imaging of a metallic target using X-rays. The generation of an ultrashort high-power low-divergent X-ray beam is performed by means of a Ti:Sapphire laser driven wake-field plasma accelerator. READ MORE

  3. 22. Kiruna Spaceport

    University essay from KTH/Arkitektur

    Author : Lukas Kvist Wiberg; [2022]
    Keywords : architecture; space; airport; science fiction; sci-fi; speculation; fantasy; Kiruna; Sweden;

    Abstract : This thesis project builds upon one of the really big questions; are we alone in the universe?By research, references and studies I have throughout this project tried to imagine a future that with the help of architectural speculation and imagination is a bit more prepared to answer that question. The project in itself was intended as an exploration of the world of science, science fiction and conspiracies, as well as typology, in order to produce architecture that represented the very notion of the longing for an answer to that question.

  4. 23. On The Run: How Fast Runaway Stars Can Escape From Their Home Cluster?

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Anna-Maria Söderman; [2022]
    Keywords : star cluster; runaway stars; velocity distribution; Physics and Astronomy;

    Abstract : Galaxies contain a wide variety of star clusters with different properties. Each cluster is a possible source of runaway stars, which can be progenitors of supernovae in other parts of the galaxy than their home cluster. Considering runaway stars in galaxy simulations has shown to increase the galactic feedback. READ MORE

  5. 24. Assessing Machine Learning Algorithms to Develop Station-based Forecasting Models for Public Transport : Case Study of Bus Network in Stockholm

    University essay from KTH/Transportplanering

    Author : Mahsa Movaghar; [2022]
    Keywords : Public transport; ridership; machine learning; Multiple Linear Regression; Decision Tree; Random Forest; Bayesian Ridge Regression; Neural Networks; Support Vector Machines; K-Nearest Neighbors;

    Abstract : Public transport is essential for both residents and city planners because of its environmentally and economically beneficial characteristics. During the past decade climatechange, coupled with fuel and energy crises have attracted significant attention toward public transportation. READ MORE

  6. 25. D-band Power Amplifiers in Vertical InGaAs Nanowire MOSFET Technology for 100 Gbps Wireless Communication

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

    Author : Patrik Blomberg; Ludvig Pile; [2022]
    Keywords : D-band; Power Amplifier; Pseudo-differential common source; Stacked; Vertical InGaAs nanowire; MOSFET; Technology and Engineering;

    Abstract : Two different topologies of power amplifiers (PAs) are designed in the frequency range 130-174.8 GHz for use in backhaul transmitters. These are the pseudo-differential common source (PDCS) and the single-ended stacked amplifier topologies. READ MORE
