  3. 7. Non-Destructive testing of concrete with ground penetrating radar

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Elias Hammarström; [2018]
    Keywords : Concrete; Non-destructive testing; Ground Penetrating Radar GPR ; Assessment; Inspection;

    Abstract : Concrete structures are susceptible to deterioration over time and it is vital to continually assess concrete structures to maintain the structural integrity and prolong the service life. In recent years there has been an increased interest in non-destructive testing of concrete, i.e. READ MORE

  4. 8. Effects of Different Fuels on Combustion Boiler Processes : The analysis of alternative fuel mixtures

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Malin Stauber Alfredsson; [2018]
    Keywords : Fluidized bed boiler; Sintering; High Temperature Corrosion; Used-wood Fired Boilers; Cl-induced Corrosion; Combined Heating Plant;

    Abstract : The objective of this study is to investigate the eect of dierent fuels on two uidized bed boiler systemsat the energy company Soderenergi's site in Igelsta, called IKV and IGV P3. Today, recovered wastewood (RWW) is the major fuel share fed into the boilers. However, with an insecure fuel supply in thefuture, other fuel types must be considered. READ MORE

  5. 9. Design and manufacture of structure and hull for large AUV

    University essay from KTH/Marina system

    Author : Billy Vendel Olofsson; [2018]
    Keywords : ;

    Abstract : The main goal with the master thesis was to design and manufacture a frame and hull to a large AUV which KTH will use in research. The general aim for the Maribot LoLo (Long Endurance, Long Range AUV) is to act as an experimental platform and tool for a wide range of research activities, where all four capabilities within the SMaRC area (Autonomy, Perception, Endurance and Communication) can be tested, improved and demonstrated.
