  1. 11. Multi-scale modelling of fire in accelerator tunnels: a CERN case study

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Melchior Schepers; [2018]
    Keywords : Multi-scale modelling; CFD; tunnel fires; FDS; CERN; particle accelerator; Technology and Engineering;

    Abstract : Multi-scale modellering is een nieuwe benadering in het modelleren van rook en brand in systemen waarbij de grootte van het domein een meer conventionele volledige 3D modellering onmogelijk maakt. Het domein wordt opgesplitst in een 1D en 3D gedeelte om zo de simulatietijd te verminderen. READ MORE

  3. 12. Shafts and rock mass strength : Calibration using numerical models

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Erik Tjäder; [2018]
    Keywords : ;

    Abstract : Orepasses and ventilation shafts are examples of mine infrastructure that are subjected to increasingstresses as the production in the Kiirunavaara mine moves to deeper levels. Falloutsand damages in these kind of excavations are already occurring and the problem can be expectedto increase in the future. READ MORE

  4. 13. PID tuning with Ant Colony Optimization (ACO) : A framework for a step response based tuning algorithm

    University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Author : Carl Johan Björk; [2018]
    Keywords : PID; self-tuning; control system; building automation; ant colony optimization; neural networks; open-loop; closed-loop; step response.; PID; självtrimning; reglersystem; byggnadsautomation; myrkolonioptimering; neurala nätverk; öppen slinga; sluten slinga; stegsvar.;

    Abstract : The building automation industry lacks an affordable, simple, solution for autonomous PID controller tuning when overhead variables fluctuate. In this project, requested by Jitea AB, a solution was developed, utilising step response process modelling, numerical integration of first order differential equations, and Ant Colony Optimization (ACO).

  5. 14. Diode laser spectroscopy for oxygen detection in the lungs of infants

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Author : Peilang Liao; [2016]
    Keywords : GASMAS; Tunable laser; Transport theory; 3D phantom; Diagnoses; Gas; Lung; Physics and Astronomy;

    Abstract : This thesis work is part of a larger project with final goal to be able to measure the oxygen concentration in the lungs of infants, using non-invasive laser spectroscopy. This thesis is specifically dealing with simulations of light transport through the upper body of infants, as well as constructing a tissue-like model (phantom) that can be used in experiments.

  6. 15. Comparison between three different CFD software and numerical simulation of an ambulance hall

    University essay from KTH/Energiteknik

    Author : Ning Li; [2015]
    Keywords : indoor environment; CFD;

    Abstract : Ambulance hall is a significant station during emergency treatment. Patients need to be transferred from ambulance cars to the hospital’s building in the hall. Eligible performance of ventilation system to supply satisfied thermal comfort and healthy indoor air quality is very important. READ MORE
