  1. 1. Modelling the full-scale N2O emissions from wastewater treatment plants for identifying mitigation strategies

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Naga Deepika Peddamudium; [2023]
    Keywords : Modelling; simulation; ASM2dISS; N2O production pathways; N2O emission factor; mitigation strategies; water and environmental engineering; Technology and Engineering;

    Abstract : Nitrous oxide (N2O) emissions, which primarily originate from the biological nitrogen removal process, dominate the release of greenhouse gases (GHGs) in wastewater treatment plants (WWTPs). N2O production occurs through dynamic microbial pathways that have a significant impact on the environment compared with other GHG emissions. READ MORE

  3. 2. Modelling Magnetism of hcp Iron under Earth’s Inner Core Conditions : Based on first-principle DFT calculations and Machine Learning

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : Linda Le; [2022]
    Keywords : Machine learning; Earth’s Inner Core; hcp Iron; Electronic structure magnetism; Density functional Theory; Local magnetic moments; Ab initio molecular dynamics; ASD-AIMD-MLLSF simulation;

    Abstract : The structure of Earth’s core remains largely a mystery. The solid inner core is believed to exist in extreme pressure and temperature conditions comparable to 300 GPa and 6000 K and consists mainly of iron, Fe. READ MORE

  4. 3. Two New Methods for Real-Time Per-Face Texture Mapping (Ptex)

    University essay from KTH/Datavetenskap

    Author : Hugo Dettner Källander; Julius Häger; [2022]
    Keywords : ;

    Abstract : Ptex (Per-Face Texture Mapping for Production Rendering) is a technology unveiled by Disney in 2008 that automatizes the process of applying textures to 3D models but is rarely used in real-time contexts, where this process is still largely manual and time consuming. This report aims to compare two new real-time methods, Reduced Traverse and Hybrid, to two existing ones, Discard and Traverse, which could give new insight into the feasibility of widespread real-time Ptex and consequent resource savings.

  5. 4. Design of flow guiding parts through CFD topology optimisation

    University essay from KTH/Fordonsdynamik

    Author : Aby Narayamparambil; [2021]
    Keywords : Topology optimisation in CFD; Ansys Fluent; Tosca Fluid; Particle track; Backflow tolerance; Topologi optimering i CFD; Ansys Fluent; Tosca Fluid; Particle track; Återflödets tolerans;

    Abstract : Scania works continuously to develop internal combustion engines and after treatment systems which can achieve low pollutant emissions and high efficiency. A major principal that Scania adopted for this goal is the Simulation Driven Development (SDD) process. READ MORE

  6. 5. An investigation of detecting potholes with UAV LiDAR and UAV Photogrammetry

    University essay from Högskolan i Gävle/Samhällsbyggnad

    Author : Linus Hedenström; Sebastian Eriksson; [2021]
    Keywords : UAV; LiDAR; photogrammetry; potholes; point clouds; SfM; paved; pavement; road; drone; UAV; LiDAR; fotogrammetri; potthål; drönare; asfalt; väg; punktmoln; SfM;

    Abstract : Potholes are caused by erosion and as such always emerging on our roadnetwork. Potholes may not only cause great damages to vehicles, but can alsocause road accidents, which in the worst case are fatal. READ MORE
