  1. 6. Modeling of the primary sludge thickening process at a wastewater treatment plant with the use of machine learning

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Eric Bröndum; [2022]
    Nyckelord :Machine Learning; Stockholms Vatten och Avfall; Primary Sludge; Dewatering; Wastewater Treatment Plant; Simulation; time series prediction; Maskininlärning; Stockholms Vatten och Avfall; Primärslam; Förtjockning; Avloppsreningsverk; Simulering; Tidsserieprediktion;

    Sammanfattning : This thesis focuses on modeling the primary sludge in the thickening process at Henrikdals wastewater treatment plant in Stockholm, Sweden. The thickening process is one of the core processes at the wastewater treatment plant, where the goal is to thicken a residual product called primary sludge. LÄS MER

  3. 7. Dynamic Performance of a Tall Building to Earthquake Loading : Finding the optimum mass and stiffness

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Andrés Alonso San Segundo; [2022]
    Nyckelord :;

    Sammanfattning : With the increasing cost of land, the development of ultra-high performance concrete, and the technological advancements in equipment and machinery, we are able to construct and refurbish skyscrapers like never before. How they are built, what materials they use, or what structural system defines them, all affect their dynamic response, which in the end is the combination of the stiffness and mass, two key parameters in engineering of tall buildings.

  4. 8. Molecular Interactions Between Xanthan Gum, Psyllium, Milk Proteins and Starches, and Their Implications on Gluten-Free Bakery Products

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Carolin Bischoff; [2021]
    Nyckelord :Rheology; Xanthan gum; Gluten-Free; Food Technology; Technology and Engineering;

    Sammanfattning : Gluten in bread can cause severe health problems in patients with celiac disease. However, gluten-free substitutions often show impaired quality characteristic like a liquid dough because of a missing gluten-network or accelerated staling due to the high amount of gluten-free starch.

  5. 9. Monitoring and Modelling of the Abiskojåkka Bridge

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Kasper Furenstam; [2020]
    Nyckelord :Prestressed bridge; Abisko; Monitoring; thermal effects; FEM;

    Sammanfattning : The infrastructure of today is getting older and problems caused by deterioration over time is affecting the service life of these structures. In Sweden most of the existing bridges were constructed 60 to 70 years ago, rising the need to determine the state of health of the bridges as the maintenance costs will increase heavily. LÄS MER

  7. 10. Algae hydrocarbons designed for bio-based lubricants

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Elin Sjöhag; [2020]
    Nyckelord :Microalgae; macroalgae; lubricant; alginate; grease; Mikroalger; makroalger; smörjmedel; alginat; förtjockningsmedel;

    Sammanfattning : Smörjmedel är en nödvändighet för maskiner för att minska slitage och energiförbrukning. Dock är över 95% av de använda smörjmedlen i dag fossilbaserade. Smörjmedel baserade på vegetabiliska oljor finns tillgängliga men har ofta en lägre oxidativ stabilitet och sämre lågtemperaturegenskaper än deras fossilbaserade motsvarigheter. LÄS MER
