  1. 11. Moving in the dark : Mathematics of complex pedestrian flows

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Meghashyam Veluvali; [2023]
    Keywords : Mathematical modelling of pedestrian dynamics; stochastic systems; evacuation time; random walk method; parabolic equation; finite difference method;

    Abstract : The field of mathematical modelling for pedestrian dynamics has attracted significant scientific attention, with various models proposed from perspectives such as kinetic theory, statistical mechanics, game theory and partial differential equations. Often such investigations are seen as being a part of a new branch of study in the domain of applied physics, called sociophysics. READ MORE

  3. 12. Antenna Options for High Altitude IMT Base Stations (HIBS) in Cellular Networks

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Harald Magnusson; [2022]
    Keywords : High altitude IMT Base Station HIBS ; High Altitude Platform Station HAPS ; Link Feasibility; Coverage Feasibility; Phased Array Antenna; Parabolic Reflector Antenna;

    Abstract : This thesis is the result of a collaboration between Ericsson AB and Luleå University of Technology. A feasibility study has been conducted to investigate antenna options for the HIBS access link. The study contains two parts. Firstly, a link budget investigating the gain required from the antenna.

  4. 13. Effects of solar parabolic- trough collectors in small- scale district heating systems

    University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Author : Alejandro Monterrubio; [2022]
    Keywords : Parabolic-trough collector; direct normal radiation; diffuse radiation; insolation; carbon abatement cost; biomass; District Heating; Levelized cost of energy;

    Abstract : Reducing carbon emissions in our societies requires a massive shift towards renewables. In Sweden, biomass is the dominant source for the district heat production, but growing demand for biomass in other sectors may cause pressure on it. READ MORE

  5. 14. Solar Energy and its Potential in Rural Botswana : a solution-driven qualitative field study with supplementary secondary research

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Patryk Törngren; Mariam Khodaverdian; [2022]
    Keywords : Solar Energy; Botswana; Solar PV; Concentrated Solar Power CSP ; Solar Water Heating; Rural Areas; Gakgatla Village; Solar Cooker; Solar Dryer; Firewood;

    Abstract : Solar energy is of huge interest due to the current situation with global warming. A number of solar technologies have been developed, such as photovoltaic, concentrated solar power, and solar water heating systems, to name a few. READ MORE

  6. 15. Homogenization of an elliptic transmission system modeling the flux of oxygen from blood vessels to tissues

    University essay from

    Author : Filippo Di Tillio; [2021]
    Keywords : ;

    Abstract : Motivated by the study of the hypoxia problem in cancerous tissues, we propose a system of coupled partial differential equations defined on a heterogeneous, periodically perforated  domain describing the flux of oxygen from blood vessels towards the tissue and the corresponding oxygen diffusion within the tissue. Using heuristics based on dimensional analysis, we rephrase the initially parabolic problem as a semi-linear elliptic transmission problem. READ MORE
