  1. 1. Physically-Based Animation of Fire for Android

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :FREDRIK ALBERS; KARL ANDERSSON; ANTON FORSBERG; LOVISA GRAHN; DANIEL OLSSON; AXEL SVENSSON; [2020-10-29]
    Nyckelord :Fire simulation; Fire simulation Android; Fluid dynamics Android; Wavelet Turbulence; Simulation GPU; Fire simulation 3D;

    Sammanfattning : Animation of fire and fluids has been around for at least 20 years in the field of computer graphics. These animations have over the years progressed into real-time simulations running on the GPU and further refined, thanks to modifications such as vorticity and wavelet turbulence, adding higher visual detail.

  3. 2. Sveriges framtida befolkningsstrukturer

    Kandidat-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Ebba Petersson; Cindy Grahn; [2018]
    Nyckelord :Demografi; befolkningspyramid; Mathematics and Statistics;

    Sammanfattning : The most central for the population to grow is the fertility rate. When the birth rate is not the most central for an individual the conditions change the population growth. The fertility rate in Sweden is around 1,88 children per woman, although there has been a drastic increase in the population. LÄS MER

  4. 3. Elbilsladdning i anslutning till bostadsfastighet : modellering av sammanlagringseffekt

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Andreas Lundgren; [2016]
    Nyckelord :aggregation effec; electric vehicles; charging power; Elbilsladdning; sammanlagringseffekt; Halo; bostadsfastighet; normalladdare; laddstationer; laddinfrastruktur;

    Sammanfattning : This thesis examines charging of electric vehicles with charging power of 3,7 kW, in connection to an apartment building in Sweden. Also the power consumption of six electric vehicles are investigated. The charging-simulations of the electric vehicles were performed with the electric vehicle charging model (Grahn-Munkhammar) in MatLab. LÄS MER

  5. 4. An Image and Processing Comparison Study of Antialiasing Methods

    M1-uppsats, Blekinge Tekniska Högskola/Institutionen för kreativa teknologier

    Författare :Alexander Grahn; [2016]
    Nyckelord :post-processing; antialiasing; real-time;

    Sammanfattning : Context. Aliasing is a long standing problem in computer graphics. It occurs as the graphics card is unable to sample with an infinite accuracy to render the scene which causes the application to lose colour information for the pixels. This gives the objects and the textures unwanted jagged edges. LÄS MER
