  1. 11. Study on feasibility of small-scale pumped hydro storage- A case study in Sweden

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Prashant Niroula; [2023]
    Keywords : energy storage; pumped hydropower; electricity market; investment; new technologies; feasibility; Technology and Engineering;

    Abstract : The European union has been aggressively pushing forward with policies favoring renewable sources of energy. As a result, the share of intermittent renewables in the European power grid is rising and is expected to grow even more in the coming decade. The Swedish energy agency also forecast huge growth in wind power. READ MORE

  3. 12. Investigation of the mean photon energy in Kompaneets spectra

    University essay from KTH/Fysik

    Author : Richárd Bagi; [2023]
    Keywords : Astroparticle Physics; Kompaneets equation; Astropartikelfysik; Kompaneetsekvationen;

    Abstract : The Kompaneets equation describes the spectrum formation when hot fermions are injected into an opaque fermion-photon plasma in thermal equilibrium and inverse Compton-scatterings occur. The equation has three free parameters, the initial plasma thermal energy θ_u, the final plasmathermal energy θ_r and the average photon energy gain y_r. READ MORE

  4. 13. Evaluating the use of Brush and Tooltip for Time Series visualizations: A comparative study

    University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Author : André Eklund; Sebastian Helin; [2023]
    Keywords : Time series visualisations; time series visualizations; Tooltip; Brush; Graphical Perception; Estimation Time; Accuracy; Line chart; Bar chart; Time series;

    Abstract : This study uses a combination of user testing and analysis to evaluate the impact of brush and tooltip on the comprehension of time series visualizations. Employing a sequential mixed-methods approach, with qualitative data from semi-structured interviews used to inform the design of a visualization tool, followed by a quantitative user study to validate it.

  5. 14. Post-operative complications after endoscopic sinus surgery in patients with chronic rhinosinusitis

    University essay from Örebro universitet/Institutionen för medicinska vetenskaper

    Author : Anna Sundström; [2022]
    Keywords : chronic rhinosinusitis; endoscopic sinus surgery; post-operative complication; navigation systems; extensive surgery;

    Abstract : Background Chronic rhinosinusitis is an inflammatory condition of the nose and paranasal sinuses lasting more than 12 weeks. The common treatment is intranasal corticosteroids but if this treatment fails in relieving symptoms endoscopic sinus surgery (ESS) is considered - a common procedure in the Otolaryngology department in Örebro county.

  6. 15. Semi-Automatic calculation of the stability of shear walls in multi-storey buildings

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Erik Bolin; Emil Sjöstedt; [2022]
    Keywords : Horizontal stabilisation; Dynamo; Shear walls; Stability; Conceptual design phase; Visual programming; Openings in shear walls; Load distribution; Relative stiffness; Technology and Engineering;

    Abstract : Performing horizontal stability analysis in the conceptual design phase is time consuming and adjustments in the geometry of the building require new time consuming calculations. Often buildings are modelled in 3D modelling software such as Revit and Tekla but the calculations are often performed in a separate software. READ MORE
