  1. 16. Mescape - A probabilistic mesoscopic model for fire evacuation in large gatherings

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Lorenzo Contini; [2022]
    Keywords : Human behaviour; crowd evacuation; mesoscopic modelling; hydraulic model; large gatherings; fire safety; performance-based design; quantitative risk assessment; consequence analysis; uncertainty analysis; probabilistic modelling; Technology and Engineering;

    Abstract : This study presents a mesoscopic model that predicts pedestrian evacuation in large gatherings with probabilistic methods. The model is based on a coarse network representation of buildings, where occupants are treated at a different scale according to their location. READ MORE

  3. 17. Models and Algorithms for Personalized Glycemic Control

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

    Author : Alma Eriksson; [2022]
    Keywords : ;

    Abstract : Glycemic control is resource-demanding in the treatment of Intensive Care Units (ICUs) patients where blood glucose measurements are taken continuously at few-hour intervals to avoid the risk of having a patient in a coma, or in the worst case, causing death. The number of diabetes patients, mostly type 2 diabetes, is increasing around the world, and at the same time, we have an ongoing pandemic of Covid-19 with health workers stretched to their limits.

  4. 18. A COMPARATIVE STUDY OF TRAVELLING FIRE IN LARGE SPACES WITH MULTI-ZONE FIRE MODEL AND FDS

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Paolo Bertoli; [2021]
    Keywords : Multi-Zone fire model; FDS; Large enclosures; Travelling fire.; Technology and Engineering;

    Abstract : A knowledge of far field temperatures is valuable for Performance Based Design structural analysis and life safety analysis, where a parametric study is needed. A fire model using multiple zones called a multi zone (MZ) fire model has in previous studies shown good potential as an analytical tool for predicting far field temperatures in large compartments.

  5. 19. Galaxies as Clocks and the Universal Expansion

    University essay from KTH/Fysik

    Author : Anders Ahlström Kjerrgren; [2021]
    Keywords : cosmology; cosmic chronometers; universal expansion; Hubble parameter; differential ages; galaxy age; relative age; cosmic time; chi-square minimization; monte carlo sampling; gaussian processes; kosmologi; kosmisk kronometer; universums expansion; Hubbleparametern; differentiell ålder; galaxålder; relativ ålder; kosmisk tid; chi-2-minimering; monte carlo-sampling; gaussiska processer;

    Abstract : The Hubble parameter H(z) is a measure of the expansion rate of the universe at redshift z. One method to determine it relies on inferring the slope of the redshift with respect to cosmic time, where galaxy ages can be used as a proxy for the latter. This method is used by Simon et al.

  6. 20. A Machine Learning Approach for Comprehending Cosmic Expansion

    University essay from KTH/Fysik

    Author : Ludvig Doeser; [2021]
    Keywords : Cosmology; Cosmic expansion; Galaxy Images; Machine learning; Kosmologi; kosmisk expansion; galaxbilder; maskininlärning;

    Abstract : This thesis aims at using novel machine learning techniques to test the dynamics of the Universe via the cosmological redshift-distance test. Currently, one of the most outstanding questions in cosmology is the physical cause of the accelerating cosmic expansion observed with supernovae. READ MORE
