  1. 1. Misfire Detection in Heavy Duty Diesel Engines Using Knock Sensors

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Carl Sjöstedt; [2023]
    Nyckelord :ICE; combustion engine; combustion engines; Scania; diesel; knock; knock sensor; knock sensors; misfire; misfire detection;

    Sammanfattning : In this thesis the possibility of using knock sensors for misfire detection in heavy duty diesel engines is investigated. This is of great interest due to many emission legislations getting stricter, especially in the US where robust misfire detection is mandatory for these types of engines. LÄS MER

  3. 2. Deriving Spectral Maps from JWST Data : A Study of Enceladus’ Plumes

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Stephan Weissenböck; [2023]
    Nyckelord :Data Analysis; Enceladus; Plumes; Atmosphere; JWST; NIRSpec; IFU; Infrared spectroscopy; Dataanalys; Enceladus; plym; atmosfär; JWST; NIRSpec; IFU; infraröd spektroskopi;

    Sammanfattning : This study investigates the presence of water vapor plumes in the region south of Enceladus, a moon in the Saturnian system, through observations conducted by the James Webb Space Telescope. Enceladus is believed to harbor a subsurface ocean or localized water reservoir that gives rise to water geysers, expelling vapor into its tenuous atmosphere and outer space. LÄS MER

  4. 3. Reconstruction of Accelerated Cardiovascular MRI data

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Hussnain Khalid; [2023]
    Nyckelord :medical imaging; deep learning; CNN; Magnetic resonance imaging; MRI; Cardiac MRI; Cardiac; Cardiovascular; reconstruction; 4D flow MRI; Parallel Imaging; Compressed Sensing; FlowVN; Flow Variational Network; K-space; Reference images; sensitivity maps; Respiratory motion; undersampled images;

    Sammanfattning : Magnetic resonance imaging (MRI), is a noninvasive medical imaging testing techniquewhich is used to produce detailed images of internal structure of the human body, includingbones, muscles, organs, and blood vessels. MRI scanners use large magnets and radiowaves to create images of the body. LÄS MER

  5. 4. Something more than itself : Mycelial beyondings: parallel engagementswith and throughmycelium as imagery, material and place

    Master-uppsats, Stockholms konstnärliga högskola/Institutionen för dans

    Författare :Hódi Csilla; [2021]
    Nyckelord :mycelium; extra-human dramaturgy;

    Sammanfattning : How could we organize as MUSHROOM(-mycelium) - is the structuring desire of my current delving. It is fictionalizing the human as something that is able to become something else through taking care. LÄS MER

  7. 5. Measuring T1 using MP2RAGE in Human Brain at 7T – Effect of B1+ and Inversion Pulse Efficiency

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Mustafa Kadhim; [2021]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction: The MP2RAGE technique has become popular for structural MRI at ultra-high fields. The core idea behind MP2RAGE is to reduce the influence of flip angle inhomogeneity (B +), proton density and T2* by calculating the regularized signed ratio of two complex MP-RAGE images acquired at different inversion times (TI) within the cycle.
