  1. 1. Solving the incompressible Navier-Stokes equations in 3-D to model gas flow in a room

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Fredrik Malmström; [2024]
    Keywords : ;

    Abstract : The thesis proposes to model the flow of gases in a room by solving the incompressible Navier-Stokes equations in three dimensions. The transportationof scalars such as temperature and concentration of CO2 is modeled by solving the advection-diffusion equation, and the effects of temperature on thevelocity is accounted for by employing the Boussinesq approximation.

  3. 2. Exploring Urban Land Cover Changes and the Effect on Nocturnal Air Temperature Dynamics in Helsingborg - A temperature modeling made with TAPM

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Amanda Bäck; [2023-10-09]
    Keywords : Nocturnal Air Temperature; Intra-Urban Heat Island; Land Cover Classification; Deep learning; The Air Pollution Model TAPM ; Land Cover Change;

    Abstract : In light of increasing global temperatures, urban areas face growing challenges related to heat stress. Alterations in land cover (LC) within cities contribute to changes in the intra-urban climate, predominantly driven by the replacement of vegetated surfaces with impermeable materials. READ MORE

  4. 3. Evaluating Brain-Inspired Machine Learning Models for Time Series Forecasting: A Comparative Study on Dynamical Memory in Reservoir Computing and Neural Networks

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

    Author : Eddie Nevander Hellström; Johan Slettengren; [2023]
    Keywords : ;

    Abstract : Brain-inspired computing is a promising research field, with potential to encouragebreakthroughs within machine learning and enable us to solve complex problems in a moreefficient way. This study aims to compare the performance of brain-like machine learningalgorithms for time series forecasting. READ MORE

  5. 4. Influence of Varying Electric Light Distribution on Melanopic Equivalent Daylight Illuminance and Lighting Energy Use

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Rebecka Ståhl; Parvathy Biju; [2023]
    Keywords : Alertness; Circadian Entrainment; Clear Sky; Correlated Colour Temperature; Daylighting; Direct Electric Lighting; Direct-Indirect Electric Lighting; Energy-Efficiency; Grasshopper; Integrative Lighting; LARK 2.0; Melanopic Equivalent Daylight Illuminance; Overcast Sky; Photopic Illuminance; Spectral Power Distribution.; Technology and Engineering;

    Abstract : Human beings in modern society spend more than 90% of their time indoors to live, work, and socialize. To improve health, quality of life and task performance, integrative lighting is designed to give the right light at the right time at the eye to stimulate circadian entrainment. READ MORE

  6. 5. A Machine Learning Approach on Analysis of Emission Spectra for Application in XFEL Experiments

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Harald Agelii; [2023]
    Keywords : Structural biology; Machine learning; Neural networks; emission spectrum; XFEL; X-ray free electron laser; SFX; Serial femtosecond X-ray crystallography; Proteins; Diagnostics;

    Abstract : In this thesis we investigate two potential applications of machine learning in the context of X-ray imaging and spectroscopy of biological samples, particularly such using X-ray free electron lasers (XFEL). We first investigate the possibility of using an emission spectrum, recorded from a sample after being probed by an incident X-ray, as a diagnostic tool. READ MORE
