  1. 16. Generation of attosecond X-ray pulses in free-electron lasers using electron energy modulation and undulator tapering

    University essay from Uppsala universitet/FREIA

    Author : Karl-Fredrik Boholm Kylesten; [2023]
    Keywords : attosecond; free-electron laser; XFEL; self-amplified spontaneous emission; SASE; tapering; energy modulation;

    Abstract : Free-electron lasers (FELs) are among the world's most intense artificial artificial sources of coherent light and are tunable to various wavelengths, including the X-ray spectrum. X-ray FELs (XFELs) are extremely useful for diffraction experiments to study molecules, materials, and quantum systems. READ MORE

  3. 17. An alternative explanation for scale-free speed correlations in starling flocks: coarse-graining in time

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Mate Jagnjic; [2023]
    Keywords : scale-free correlations; active matter; starling flocks; coarse-graining;

    Abstract : In a celebrated series of experimental observations, starling flocks have been shown to be characterized by scale-free, long-ranged spatial correlations in their velocity fluctuations. While this is expected for velocity orientation correlations on the basis of simple symmetry-breaking arguments, the same scaling-free behaviour for speed (i.e. READ MORE

  4. 18. Evaluating electrolyser setups for hydrogen production from offshore wind power : A case study in the Baltic Sea

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Kenzo Franzén; [2023]
    Keywords : electrolysis; energy systems modelling; green hydrogen; offshore wind power; power-to-x; electrólisis; energía eólica marina; hidrógeno verde; modelado de sistemas de energía; power-to-x;

    Abstract : As part of the transition towards a fully sustainable energy system, green hydrogen shows great potential to decarbonise several hard-to-abate sectors. To provide the fossil-free electricity required for electrolysis, offshore wind power has emerged as a suggested option. READ MORE

  5. 19. Support for autonomously driven systems in harsh environments. : Degree project for Master of Science in mechanical engineering with focus on innovation and sustainable product development

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Mohammed Aljafari; [2023]
    Keywords : Sensor; Temperature measurement; Maintenance free; Autonomous system; Sensor; Temperatmätning; Underhållsfri; Autonomt system; Design thinking;

    Abstract : Symptoms of harsh environments create pressure on autonomous machines to work wellwith the use of measurement devices. Sensors used within construction equipment vehiclessuffer from being covered with fogs of dirt, oil, water, and dust. READ MORE

  6. 20. Dioxins: An Easy Problem to Solve or a Hard-Fought Battle for the Environment? a Case Study of How and Why the Pulp and Paper Industry in Sweden Transitioned Away From Chlorine-Bleaching

    University essay from Lunds universitet/Sociologiska institutionen; Lunds universitet/Sociologi

    Author : Marcus Aronsson; [2023]
    Keywords : environmental sociology; ecological modernization; treadmill of production; middle-range; industrial transition; Social Sciences;

    Abstract : The situation for the environment is in many ways dire. However, amidst all the negative environmental developments it is easy to neglect the successes that have actually happened. READ MORE
