  1. 1. Urban green space as a matter of environmental justice : The case of Lisbon’s urban greening strategies

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Jessica Verheij; [2019]
    Nyckelord :Green Infrastructure; environmental justice; Lisbon; urban greening;

    Sammanfattning : In the summer of 2018 the European Commission awarded Lisbon as European Green Capital 2020 – in part due to investments made by Lisbon municipality in Green Infrastructure (GI) and new green spaces. As the city is becoming greener, this study aims to analyze Lisbon’s urban greening strategies from an environmental justice perspective. LÄS MER

  2. 2. Simulations of a back scatter time of flight neutron spectrometer for the purpose of concept testing at the NESSA facility.

    Master-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Benjamin Eriksson; [2018]
    Nyckelord :fusion; JET; Geant4; NESSA; NESSA facility; back scatter tof; tof; time of flight; spectrometer; neutron; ITER; Monte Carlo; simulation;

    Sammanfattning : A back scatter time of flight neutron spectrometer consisting of two scintillation detectors is simulated in Geant4 to examine whether it is possible to perform a proof of concept test at the NESSA facility at Uppsala University. An efficiency of ε = 2.45 · 10^-6 is shown to be large enough for a neutron generator intensity of 1. LÄS MER

  3. 3. Energy Storage System for Wind-Diesel Power System in Remote Locations

    Magister-uppsats, Högskolan i Gävle/Energisystem

    Författare :Roberto Cordeiro; [2016]
    Nyckelord :Energy Storage; Energy Storage System; Energy Storage Technology; ESS; Wind Diesel Power System; WDPS; Wind Turbine; Wind Penetration; Energy Systems Simulation; reMIND;

    Sammanfattning : The aim of this thesis is to show how much fuel can be saved in a power system based in diesel generators with integrated wind turbine (WDPS – Wind Diesel Power System) when a storage system is integrated. Diesel generator is still the most used power system for remote locations where the conventional grid doesn’t reach and its integration with wind turbine is seen as a natural combination to reduce diesel consumption.

  4. 4. Second-order FE Analysis of Axial Loaded Concrete Members According to Eurocode 2

    Master-uppsats, KTH/Betongbyggnad

    Författare :Nessa Yosef Nezhad Arya; [2015]
    Nyckelord :Second-order; nonlinear; slender reinforced concrete column; ABAQUS; FE analysis; curvature method; nominal stiffness method; eccentrically loaded; benchmark experiment; parametric study; Andra ordningens effekt; icke-linjär; slank armerad betongpelare; ABAQUS; FE-modellering; krökningsmetoden; styvhetsmetoden; excentrisk last; utvärderingsförsök; parameterstudie;

    Sammanfattning : A nonlinear finite element analysis was performed for an axial loaded reinforced concrete column subjected to biaxial bending taking into account second-order effects. According to Eurocode there are two ways to take second-order effects into consideration: nonlinear FE analysis and hand calculation based on the simplified methods explained in Eurocode 2. LÄS MER

  5. 5. Temperatursprickor i ung betong : Utvärdering av projektering och utförande av åtgärder, samt utveckling av dimensioneringsmetod för kylsystem

    M1-uppsats, KTH/Byggteknik och design

    Författare :Sara Tilfors; Nessa Yosef Nezhad Arya; [2011]
