  1. 21. Bacteria - based self - healing mortar with bio - plastic healing agents : Comparative analysis on quantification and characterization of self-healing by various experimental techniques

    University essay from KTH/Betongbyggnad

    Author : Rahul Roy; [2020]
    Keywords : Mortar; crack; autonomous healing; bacteria; bioplastic; lactic acid derivatives PLA ; alkanoate derivatives AKD ; internal crack geometry; quantification; characterization; statistical analysis; Bruk; sprickbildning; självläkning; bakteriebaserademedel; bioplast; mjölksyrederivat PLA ; alkanoatderivat AKD ; inre sprickbildning; kvantifiering; karakterisering; statistisk analys;

    Abstract : Crack formation in concrete structures due to various load and non-load factors leading to degradation of service life is very common. Repair and maintenance operations are, therefore, necessary to prevent cracks propagating and reducing the service life of the structures. READ MORE

  3. 22. Nonequilibrium gauge field in Two Particle Irreducible real time formalism

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Rasmus Hansen; [2019]
    Keywords : Gauge field; non-equilibrium; quantum field theory; Physics and Astronomy;

    Abstract : The purpose of this thesis is to study what effect a photon field has on the equations of motion and the decay of a charged scalar field in thermal equilibrium at finite temperature and outside of thermal equilibrium. To do this we calculate the two-particle irreducible effective action for the mean fields and propagators and derive their equations of motion. READ MORE

  4. 23. Local Buckling of Doubly-Symmetric I-Sections Subjected to Warping Torsion : The limitations of the Reduced Cross-Section Method under unconventional loading

    University essay from KTH/Bro- och stålbyggnad

    Author : Miklós Ori; [2019]
    Keywords : Local plate buckling – Warping torsion – Finite element modelling - Eurocode;

    Abstract : In regular design practice, when it comes to conventional loading, such as uniaxial compression and bending, the local buckling of thin plates is taken care of through cross section classification. The effect of warping torsion, which also gives rise to normal stresses in the section, however, is typically not considered in the process. READ MORE

  5. 24. Experimental investigation of a de-icing system for wind turbine blades based on infrared radiation

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Sofia Sollén; Jennifer Pettersson; [2019]
    Keywords : Wind power; Wind turbine; Cold climate; Ice and snow; De-icing; De-icing system; Infrared radiation; Infrared heater.;

    Abstract : Wind power is one of the fastest growing production methods of electric energy. The expansion of wind power in Sweden are focused to northern counties. There are advantages as good wind conditions and large unexploited areas to build wind farms in the north, but there are also problems caused by the long winters. READ MORE

  6. 25. Modeling of pore pressure in a railway embankment

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Marcus Vestman; [2018]
    Keywords : PLAXIS; Pore pressure; Railway;

    Abstract : LKAB and Trafikverket want to increase the maximum allowed axial load from 30 tons to 32,5 tons for the northern part of Malmbanan. There are ongoing investigations of the condition of the railway with the current axial load of 30 tons. The investigations do not include one of Trafikverket's concerns about the condition of the railway. READ MORE
