    Abstract : Renewable energies are believed to play the key role in assuring a future of sustainable energy supply and low carbon emissions. Particularly, this thesis focus on wave energy, which is created by extracting the power stored in the waves of the oceans. READ MORE

  5. 13. Exploring Polymer-Shelled Microbubbles: Detection Modeling and Application

    Author : Hongjian Chen; Dmitry Grishenkov; Birgitta Janerot-Sjöberg; Tomas Jansson; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ultrasound contrast agent; polymer-shelled microbubble; ultrasound imaging; contrast pulse sequence; microbubble model; hydrodynamic cavitation; Technology and Health; Teknik och hälsa;

    Abstract : Ultrasound imaging (US) is widely used in clinical practice. Given the low cost and easy access to the ultrasound machine, US has a great potential to improve the health care condition for the majority of the population in the world. The US could be significantly improved by injecting ultrasound contrast agents to opacify the bloodstream. READ MORE
