  1. 6. Evaluating the impact of agriculture on albedo using Sentinel-2 data in southern Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Victor Andréasson; [2023]
    Nyckelord :Physical geography and ecosystem science; Remote sensing; Sentinel-2; Albedo; Agriculture; Earth and Environmental Sciences;

    Sammanfattning : The climate impact of food production plays a big part in the anthropogenic climate impact. Mitigation strategies from this sector are hence of great importance. One area which mainly has been used to calculate climate impact is albedo, the overall reflectance of incoming radiation in all directions. LÄS MER

  3. 7. Improving the Accuracy of FFT-based GPGPU Ocean Surface Simulations

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

    Författare :Jacob Eriksson; Joakim Wingård; [2022-12-01]
    Nyckelord :computer graphics; 3D graphics; real-time rendering; Fourier transform; FFT; simulation; GPGPU; interactive; ocean wave spectrum; oceanography;

    Sammanfattning : In this paper, we explore how the current state of the art in real-time ocean simulations can be improved in terms of simulation accuracy, while preserving performance. Current methods, both in academia and in the industry, simulate an ocean model in frequency space on the GPU, convert said model on an approximately frame-byframe basis to the spatial domain using the Fourier transform, and then read back the resulting heightfield to the CPU as input to the application’s physics engine.

  4. 8. CNC Engraver : Precision and flexibility of a miniature CNC engraver

    Magister-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Rasmus Booberg; Martin Borgén; [2022]
    Nyckelord :CNC; Engraver; Arduino; diamond drag bit; GRBL; CNC; Gravyrmaskin; Arduino; diamond drag bit; GRBL;

    Sammanfattning : This report documents the design and construction of a computer-controlled engraver (CNC engraver). Whereas most common machines used for this purpose are dimensioned towards milling, this project aims to create a dedicated engraver which could be of reduced size and complexity in comparison to standard CNC routers.

  5. 9. Värmetröghet i byggnader : En studie som undersöker en skolbyggnad utifrån olika materials värmetröghet samt dess klimatpåverkan genom en livscykelanalys

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Kerstin Axelsson; [2022]
    Nyckelord :värmetröghet; LCA; byggnadsmaterial;

    Sammanfattning : Thermal inertia is defined as “a measure of the responsiveness of a material to variations in temperature”. This means that materials with high thermal inertia will show small changes in temperature during a cycle of time and vice versa. LÄS MER

  7. 10. Dimensionering av en väggskiva enligt fackverksmetoden : En jämförelse mellan FEM-Design och handberäkningar

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Akar Ardalani; Kamand Ali; [2022]
    Nyckelord :;

    Sammanfattning : FEM-Design, is a software program for analysis of structural systems using mathematical models and simulations. The technique is used to calculate physical properties of structures, such as stresses and deformations. LÄS MER
