    Nyckelord :Climate change; carbon dioxide emissions; foundations; concrete; load-bearing capacity; foundation methods; climate impact; Klimatförändringar; koldioxidutsläpp; fundament; betong; bärförmåga; grundläggningsmetoder; klimatpåverkan;

    Sammanfattning : Climate change due to greenhouse gases is an important challenge the world is facing. In the manufacture of building materials, concrete accounts for about 50% of all greenhouse gas-emissions. A general way of reducing emissions is to replace concrete with other materials with lower climate impact. LÄS MER

  3. 22. Occupancy detection and prediction with sensors and online machine learning : Case study of the Elmia exhibition building in Jönköping

    Master-uppsats, KTH/Byggvetenskap

    Författare :Allen Chen; [2022]
    Nyckelord :;

    Sammanfattning : Buildings account for approximately 40% of energy consumption in the EU, and despite drastic increasing measures for energy efficient operation, the net value of energy consumption is expected to continue increasing because ofincreasing urbanization.While there has been increasing work done on managing external loads such as adapting to unpredictable climates, the research on internal loading, such as occupants, is still nascent.

    Sammanfattning : Health monitoring devices, such as Fitbit, are gaining popularity both as wellness tools and as a source of information for healthcare decisions. Predicting such wellness goals accurately is critical for the users to make informed lifestyle choices. LÄS MER

  5. 24. Optimering av spillvattenflöden

    Master-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Filip Berglund; [2022]
    Nyckelord :Optimization; Wastewater network; Optimal control; Pumping system; Optimering; Spillvattennätverk; Optimal styrning; Pumpsystem;

    Sammanfattning : This thesis aims to produce a control strategy that minimizes the energy usage of the pumps in the sewer system of Växjö City. The pumps are located in a small number of pumping stations. These are connected by a network of pipes in a way that requires the control of the pumps to be coordinated, both within and between the pumping stations. LÄS MER

  7. 25. Energieffektivisering av membranluftrengöring vid högflödesperioder : Studie på en storskalig MBR-pilot på Syvab Himmerfjärdsverket i samarbete med SUEZ Water Technologies and Solutions

    Master-uppsats, Karlstads universitet

    Författare :Patrik Bou-Rached; [2022]
    Nyckelord :MBR; membrane air scouring; trans membrane pressure; luftflöde; membranluftrengöring; transmembrantryck;

    Sammanfattning : Membrane BioReactor (MBR) is a wastewater treatment method which combine both biological and physical cleaning. In the membrane tank there is membrane fibres which physically separate wastewater from containing organic material. This causes the membrane fibres to easily build fouling. LÄS MER
