  1. 1. Non-destructive testing of thin strip material : Implementation of the 3MA technique at a steel producing company

    University essay from Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Author : Jon Mikel Lizarralde; [2017]
    Keywords : Non-destructive testing; 3MA; steel strip; process monitoring and control; energy efficiency; sustainability; hardness; tensile strength;

    Abstract : This study is an initial attempt to investigate the possibility of substituting conventional laboratory destructive testing techniques at Sandvik's strip steel production facilities with the 3MA (Micro-magnetic Multi-parameter Microstructure and Stress Analysis) NDT (nondestructive testing) technique. The interest for the research comes from various problems with the actual destructive testing method. READ MORE

  3. 2. Analys av metanflöden från sjön Erken

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Ryan Mintz; [2016]
    Keywords : methane; transfer velocity; flux; waterside concentration; eddy covariance; Nyckelord: metan; utbyteskoefficient; flux; metankoncentration; eddy kovarians;

    Abstract : While it is not the most abundant greenhouse gas, a significant portion of the greenhouse effect is caused by methane. The amount of methane in the atmosphere is increasing, indicating that there is a continuous source of methane to the atmosphere. READ MORE

  4. 3. Optimal placement of plasma actuators on trucks : A drag reduction study using adjoint methods

    University essay from KTH/Aeroakustik

    Author : Samuel Gottfarb Bart; [2016]
    Keywords : ;

    Abstract : The fuel consumption of vehicles plays an important environmental role and ways of improving the fuel economy is beneficial for a sustainable future. Active flow control is one method that can potentially reduce the aerodynamic drag significantly and therefore the fuel consumption. READ MORE

  5. 4. Evaluation of the Inertial Dissipation Method over Land

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Björn Carlsson; [2003]
    Keywords : inertial dissipation method; air-sea interaction; eddy correlation method; similarity theory;

    Abstract : The focus was to evaluate the Inertial Dissipation Method (IDM) over land duringunstable conditions. This was done by comparing the friction velocity, u*, from theeddy-correlation method (ECM) with u* from IDM. READ MORE
