  1. 1. Phase Unwrapping MRI Flow Measurements

    University essay from Uppsala universitet/Avdelningen Vi3

    Author : Mio Liljeblad; [2023]
    Keywords : phase unwrapping; computer vision; cine MRI; NMR; flow measurements; velocity encoding; venc; energy minimization; magnetic resonance; cardiac MRI; sinotubuar junction; pulmonary artery; ascending descending aorta; laplacian algorithm; iterative graph cuts; IGC; sequential tree-reweighted message passing; TRW-S; velocity to noise ratio; VNR; retrospective wrapping; energy formulation;

    Abstract : Magnetic resonance images (MRI) are acquired by sampling the current of induced electromotiveforce (EMF). EMF is induced due to flux of the net magnetic field from coherent nuclear spins with intrinsic magnetic dipole moments. READ MORE

  3. 2. 5G Technological Innovation: Advantages and potential consequences in developing Smart City

    University essay from Uppsala universitet/Industriell teknik

    Author : Md Munsur Uddin; [2023]
    Keywords : Technological Innovation; 5G enabled Technologies; Smart City; Advantages; Potential Consequences;

    Abstract : The purpose of this research is to study the advantages of 5G technological innovation in the development of smart cities, i.e., to find out in what way this technology plays the main driving force of other relevant technologies essential to developing smart cities. READ MORE

  4. 3. Assessment of Exposure to Electromagnetic Fields from Distributed MIMO Antennas

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Frans Nyberg Zou; [2022]
    Keywords : 6G; Distributed MIMO; Electromagnetic field exposure; Hybrid simulations; 6G; Distribuerad MIMO; Exponering av elektromagnetiska fält; Hybridsimueringar;

    Abstract : Research on 6G telecommunication networks has been initiated. Among all potential technology components, the distributed multi-input multioutput (D-MIMO) technology is one of the promising enablers. Due to the new technology solutions, additional methodologies for assessment of electromagnetic field (EMF) exposure need to be developed. READ MORE

  5. 4. Wood and moisture-induced strains in a large deformation setting in 3D

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Fredrik Ström; Anwar Obeido; [2022]
    Keywords : Total Lagrangian; Finite element method; Large deformation theory; Deformation gradient decomposition; Moisture-induced strains; Hygroscopic; Orthotropic.;

    Abstract : Many studies have previously been done on moisture-induced strains in wood. An in- finitesimal/engineering strain model has been used for most of these studies, which is often an accurate approximation for small rotations. However, if large deformations oc- cur, then fictive strains are obtained resulting from the simplified engineering strain. READ MORE

  6. 5. Generating Product-Service Design Improvements from a Climate Impact and Energy Use Perspective Using Life Cycle Assessment : The Case of Vertical Access Equipment

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Vishnu Teja Tirumalasetty; Max Olof Jonas Bäck; [2021]
    Keywords : Life Cycle Assessment; LCA; Product-Service System; PSS; Vertical Access Equipment; Circular Economy;

    Abstract : Climate change is connected to several negative effects on local environments around the globe such as, longer, and more intense droughts, less freshwater supplies, ocean warming, sea level rise, polar ice melting, more intense storms, and rainfall (NASA, 2021).  These problems are mainly due to the increasing amount of carbon dioxide in the atmosphere as well as other greenhouse gases (GHG) which cause a similar or stronger climate change effect (WWF, 2021).
