  1. 1. Synthesizing of brain MRE wave data

    Master-uppsats, KTH/Medicinsk avbildning

    Författare :Maryia Yuliuhina; [2023]
    Nyckelord :MR elastography; brain MRE; synthetic data; computational modeling; shear wave elastography; MR-elastografi; hjärn MRE; syntetiska data; beräkningsmodellering; skjuvvåg elastografi;

    Sammanfattning : Magnetic resonance elastography (MRE) is an imaging technique that allows for non-invasive access to the physical properties of body tissues. MRE has great potential, but it is difficult to conduct research due to the time-consuming estimation of stiffness maps, which could be speeded up by using neural network. LÄS MER

    Sammanfattning : Battery electric trucks (BETs) offer environmental benefits in terms of reduced carbon emissions and enhanced energy efficiency but have been challenged with economic viability compared to conventional internal combustion engine trucks (ICETs) caused by substantial acquisition costs, limited charging infrastructure, and concerns regarding range and payload capacity.  Previous studies focus on TCO at the vehicle or policy level but overlook the system and firm-level impacts.

  4. 3. Investigation of the effect of alloying elements on the printability of biodegradable material

    Master-uppsats, KTH/Flerskalig materialmodellering

    Författare :Fikan Mubarok Rohimsyah; [2019]
    Nyckelord :;

    Sammanfattning : The integration of biodegradable implant into the human body must meet both engineering and physiological requirements. The properties of magnesium such as low density, high specific strength and other biocompatibility properties makes magnesium and its alloy suitable for several biodegradable implant application.

  5. 4. Evaluation of novel S-ICD electrode placements using computational modeling

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Anne-Marie Plancke; [2018]
    Nyckelord :ICD; modeling;

    Sammanfattning : OBJECTIVES The aim of this study is to investigate the influence of new subcutaneous Implantable Cardioverter Defibrillator (ICD) electrode placements on the Defibrillation Threshold (DFT), shock impedance, and sites of activation in the heart caused by a low voltage shock. BACKGROUND The subcutaneous ICD, though it has many advantages due to its less invasive nature compared to the transvenous ICD, requires higher energy shocks to terminate ventricular arrhythmias, and is not currently thought to be able to reliably pace the heart.
