  1. 1. Optimization in Design of End-Bearing Concrete and Steel Piles with Regard to Climate Impact : Climate Conscious Material Choices in Early Project Planning

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Simat Adnan; Jann Ton; [2021]
    Nyckelord :Design; End-bearing piles; Bearing capacity; GWP; LCA; Climate change; Dimensionering; Spetsburna pålar; Bärförmåga; GWP; LCA; Klimatpåverkan;

    Sammanfattning : Environmental sustainability is becoming more popular in the building industry. Sustainable thinking needs to be present during the whole construction process, from the idea phase to the final stages. LÄS MER

  3. 2. Nitrogen Removal in a Vacuum Tank Degasser : An Investigation on the Nitrogen Removal Performance

    Master-uppsats, KTH/Materialvetenskap

    Författare :Björn T. I. Ahlin; [2019]
    Nyckelord :Nitrogen Removal; VTD;

    Sammanfattning : The impending change of processes at SSAB Oxelösund due to the HYBRIT project, where the blast furnace and LD converter are to be replaced with an EAF will have a significant impact on the manufacturing of steel in Oxelösund. One issue that will arise is the nitrogen content in the steel. LÄS MER

  4. 3. Thermal Analysis of a Sea Wave Generator

    Master-uppsats, KTH/Elkraftteknik

    Författare :Ezequiel Quijada; [2017]
    Nyckelord :sea wave power generator; magnet overheating; demagnetization; heat transfer; conjugate heat transfer; thermal resistance; Comsol Multiphysics; cooling technique;

    Sammanfattning : Wave power has been increasing the interest of many researchers looking for alternative sustainable energy sources since the reserves have proved to be capable of satisfying a considerable percentage of the world´s energy demands. This option has not been adopted as a sustainable source since there are some challenges in the process of designing a low cost device that converts the kinetic energy of the waves into electric energy and that could still be efficient enough to be competitive against other options.

  5. 4. Quenching and tempering hardness response of front axle steel beams : Different material properties during quenching and tempering

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Simon Zemui; [2017]
    Nyckelord :Axle steel beams; hardness; Quenching; tempering;

    Sammanfattning : The aim of this thesis was to investigate what the relation is between as-quench hardness and final surface hardness for steel beams is, depending on what tempering temperature is used. Also explain how chemistry, dimension and microstructure effects the final mechanical properties of the front axle beam. LÄS MER

  7. 5. Constructing with wood : What are the economical and environmental benefits and barriers of using wood as a construction material

    Master-uppsats, KTH/Fastigheter och byggande

    Författare :John Waldenström; [2017]
    Nyckelord :Wood; environment; economics; trä; miljö; ekonomi;

    Sammanfattning : One of the biggest issues of our time is the environment. In December 2015, 195 countries agreed to the first-ever universal, legally binding global climate deal, The Paris Protocol – A blueprint for tackling global climate change beyond 2020. LÄS MER
