  1. 1. Supercritical Carbon Dioxide Brayton Cycle for Power Generation : Utilizing Waste Heat in EU Industries

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :BJÖRN J. THORSSON; HADY R. SOLIMAN; [2020]
    Nyckelord :;

    Sammanfattning : The industrial sector accounts for approximately 30% of the global total energy consumption and up to 50% of it is lost as waste heat. Recovering that waste heat from industries and utilizing it as an energy source is a sustainable way of generating electricity. 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. A digital image correlation method for detection of fatigue cracks in non-load carrying T-joints

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Björn Jonsson; [2018]
    Nyckelord :;

    Sammanfattning : In dynamical loaded welded structures fatigue life is often a limiting factor. Common practise is to reduce nominal stress by increased material thickness which leads to oversized, heavy structures. Those practises are replaced by improvement of production and designingtechniques to utilize better properties of high strength steels. LÄS MER

  5. 4. Automated Classification of Steel Samples : An investigation using Convolutional Neural Networks

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Björn Ahlin; Marcus Gärdin; [2017]
    Nyckelord :CNN; Automated classification; Inclusions; Steel; CNN; Automatisk klassificering; Inneslutningar; Stål;

    Sammanfattning : Automated image recognition software has earlier been used for various analyses in the steel making industry. In this study, the possibility to apply such software to classify Scanning Electron Microscope (SEM) images of two steel samples was investigated. LÄS MER

  7. 5. Bro med huvudbalkar av stål och brobaneplatta av limträ

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Avdelningen för Konstruktionsteknik

    Författare :Björn Israelsson; [2012]
    Nyckelord :Samverkansbro; vippning; finita elementanalys; SAP 2000; brottgränstillstånd; bruksgränstillstånd; skjuvbuckling; spänningskapacitet; Technology and Engineering;

    Sammanfattning : In this thesis a bridge with main girders of steel and a bridge deck made out of glulam is studied. The bridge is compared with an existing composite bridge built in Kalix, Sweden. Initially both bridge solutions are presented and some detail descriptions is presented for the bridge with the glulam deck. LÄS MER
