  1. 1. Low-carbon concretes in infrastructures : Applicability, potential and carbon footprint focusing on the Parisian Metro Line L18

    Master-uppsats, KTH/Betongbyggnad

    Författare :Romain Durand; [2022]
    Nyckelord :;

    Sammanfattning : Low-carbon concretes are more and more commonly used to limit the environmental impact of concrete structures. Among concrete structures, infrastructures are characterized by their high load-bearing function (foundations, bridges, aqueducts, dams, etc.). LÄS MER

  2. 2. Assessment of calculation methods for Primary Energy Factors : Case Study of Swedish electricity mix

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Javier Ferrero Andrés; [2022]
    Nyckelord :Primary Energy; Primary Energy Factor; Calculation methods; Partial Substitution; Exergy; Physical Energy Content;

    Sammanfattning : The use of the concept of "primary energy" is present in all types of regulations at both European and national level, so that all aspects related to the reduction of energy use and energy efficiency measures speak in terms of primary energy and Primary Energy Factors, necessary for its conversion. The existing consensus on the use of the term is not such in terms of the methodology for calculating the Primary Energy Factors to be adopted, which is the reason for the search for a methodology that acquires the status of global and standard.

  3. 3. Improving the Efficiency of Thermal Energy Usage in Residential Buildings by Heat Recovery from Wastewater

    Master-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Pranjal Jain; Khaled Alturkmani; [2021]
    Nyckelord :Wastewater; Heat Exchangers; Heat Pumps; Biofilms;

    Sammanfattning : This study aims to rationalize the consumption of thermal energy in residential buildings by recovering heat from wastewater inside the building before entering the central sewage network outside the building, by conducting an analytical study for a residential tower in Syria to find out the coverage percentage of the heat energy recovered from wastewater for the heating and domestic hot water loads needed for the tower, and calculating the percentage of reduction in carbon dioxide (CO2) gases. It is a simple technology as the thermal recovery system consists of three main components, which are in order: a wastewater tank, heat exchangers, and a heat pump. LÄS MER

  4. 4. Probabilistic non-linear finite element analysis of concrete buttress dams

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Adrian Ulfberg; [2019]
    Nyckelord :ATENA; FREET; SARA; probabilistic; numerical; Kalhovd; FEA; FEM;

    Sammanfattning : Assessment of concrete buttress dams today consists of using analytical methods to investigate the stability in different failure modes. However, they simplify the problem at hand and neglect certain important features linked to geometry and thus not truthfully appraise the structures real stability. LÄS MER

  5. 5. Utmattningsanalys av marin ångpanna : Sunrod CPDB12

    Kandidat-uppsats, Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

    Författare :Joacim Castenson; Moa Grandics; [2018]
    Nyckelord :Fatigue analysis; Marine boiler; Fatigue assessment; Utmattningsanalys; Marin ångpanna; Nominella spänningsmetoden;

    Sammanfattning : Problematik med utmattningsbrott är känt sedan början på 1800-talet och fenomenet har studerats sedan dess. Efter lång tids arbete har man hittat en metodik för att ta fram analytiska beräkningsmodeller samt säkra och noggranna livslängdsberäkningar för stålkonstruktioner. LÄS MER
