  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. 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).

  4. 3. Developing a Graphical Application to Control Stepper Motors with Sensorless Load Detection

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Mattias Adolfsson; [2021]
    Keywords : Stepper motor; Sensorless; Load detection; Back-EMF; Graphical control; StallGuard; Homing; Linear stage;

    Abstract : For positioning of linear stages in absolute coordinates, there is a general need to find a reference position since the initial one is unknown. This is commonly called homing. To reduce costs and facilitate assembly, homing can be performed without additional sensors, known as sensorless homing. READ MORE

  5. 4. ENABLING THE EXCHANGE OF METAMODELS DEFINED IN ECORE FROM JETBRAINS MPS TO EMF

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Hilal Taha; [2021]
    Keywords : MPS; Eclipse; Ecore;

    Abstract : Model-Driven Engineering has been developing since the first release of the Unified Modeling Language, passing several milestones and advancing ever since. Model-Driven Engineering is being used in various fields like medical, cyber-physical systems, web applications, etc. READ MORE

  6. 5. Performance analysis of motor for electric aviation

    University essay from

    Author : Torkel Svenson Hagström; [2020]
    Keywords : ;

    Abstract : With a rising interest and improving technology regarding electric aviation, the Swedish ELISE-project aims to built a functional 21-seated electric aircraft by the year 2025. The aim of this thesis is to analyze the performance of a scalable model of an electric motor optimized for aircraft, in terms of magnetic leakage flux, generated back-EMF, torque constant and efficiency.
