  1. 6. Unsupervised Image Enhancement Using Generative Adversarial Networks : An attempt at real-time video enhancement

    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

    Author : Fredrik Gustafsson; [2021]
    Keywords : machine learning; GAN; image enhancement; unsupervised training; maskininlärning; GAN; bildförbättring; oövervakad inlärning;

    Abstract : As the world has become more connected meetings have moved online. However, since few have access to studio lighting and uses the embedded webcam the video quality can be far from good. Hence, there is an interest in using a software solution to enhance the video quality in real time. READ MORE

  3. 7. Dematerialization: good, but not good enough

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Pontus Klasman Gustafsson; [2020]
    Keywords : decoupling; dematerialization; economic growth; green growth; degrowth; raw materials; frikoppling; ekonomisk tillväxt; grön tillväxt; nerväxt; naturresurser; råvaror;

    Abstract : Global raw material extraction has accelerated since the 1950s, causing resource depletion, ecosystem degra- dation, pollution, and climate change. To reduce such impacts, the economic drivers of material use must be addressed. Although economic growth often drives material use to increase, this increase can be counter- acted by dematerialization. READ MORE

  4. 8. Relativistic attosecond electron pulses by laser wakefield acceleration

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

    Author : Cornelia Gustafsson; [2020]
    Keywords : laser wakefield accelerator; laser wakefield acceleration; attosecond; electron pulses; Physics and Astronomy;

    Abstract : The search for cheaper and more compact accelerators has led to the development of laser-driven plasma-based accelerators. In comparison to conventional particle accelerators, the plasma-based accelerator is inherently insensitive to the breakdown of the acceleration structure and therefore greater accelerating fields can be obtained.

  5. 9. Pearls as bycatch mitigation strategy for Harbour porpoise (Phoecena phoecena)

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Sara Gustafsson; [2020]
    Keywords : harbour porpoise; bycatch mitigation; acoustic reflector; pearl; gillnet; F-POD; click rate; click behaviour; inter-click-interval; terminal buzz; diel phase; GAM;

    Abstract : One of the major threats to harbour porpoise population sustainability is thought to be the high incidence of bycatch specifically in gillnets. This study aims to examine the use of acrylic class pearls developed in an earlier study as acoustic reflectors on gillnets in an effort to increase their visibility to echolocating harbour porpoises in the lumpsucker fishery in Kattegatt.

  6. 10. An Explorative Design Study of a Booking System : Evaluating the Usability and Experience of a User Interface for Novice Admin Users

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Filip Gustafsson; [2019]
    Keywords : Usability evaluation; Explorative design; Prototyping; User interface; Information visualization; System Usability Scale; Novice admin users; Heuristics; Persona Workshop;

    Abstract : This study explored how the UI of booking sunbeds could be designed to be efficient and effective while being satisfactory to use for novice admin users of the system. Personas were created through a workshop that together with visual heuristics helped drive the design of an initial paper prototype that was evaluated with users. READ MORE
