  1. 1. Internal combustion engine durability monitor : Identifying and analysing engine parameters affecting knock and lambda

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Pontus Jääskö; Petter Morén; [2021]
    Nyckelord :Internal combustion engine; durability testing; data analysis; Otto engine; ignition; ignition timing; fuel injection; Air fuel ratio; partial least squares regression PLSR ; lambda; engine knock;

    Sammanfattning : This study has been performed at Powertrain Engineering Sweden AB (PES), a fully owned subsidiary of Volvo Cars Group, which is constantly working to develop and improve internal combustion engines. As part of this work, durability tests are performed to analyse the impact of wear on the engines. LÄS MER

  3. 2. Quantifying nitrogen oxides and ammonia via frequency modulation in gas sensors

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Marcos Freitas Mourao dos Santos; [2021]
    Nyckelord :Nitrogen oxides; nox; ammonia; sic-fet; PLSR; quantification;

    Sammanfattning : The use of Silicon Carbide Field Effect Transistor (SiC-FET) sensors in cyclic operation is a proven way to quantify different gases. The standard workflow involves extracting shape-defining features such as averages and slopes of the sensor signal. LÄS MER

  4. 3. SYSTEM IDENTIFICATION OF A WASTE-FIRED CFB BOILER : Using Principal Component Analysis (PCA) and Partial Least Squares Regression modeling (PLS-R)

    Kandidat-uppsats, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Andreas Hassling; Simon Flink; [2017]
    Nyckelord :Household Waste; Incineration; MWS; PCA; PLS-R; System identification; Waste Management;

    Sammanfattning : Heat and electricity production along with waste management are two modern day challenges for society. One of the possible solution to both of them is the incineration of household waste to produce heat and electricity. LÄS MER

  5. 4. Methods of high-dimensional statistical analysis for the prediction and monitoring of engine oil quality

    Master-uppsats, KTH/Matematisk statistik

    Författare :Fredrik Berntsson; [2016]
    Nyckelord :;

    Sammanfattning : Engine oils fill important functions in the operation of modern internal combustion engines. Many essential functions are provided by compounds that are either sacrificial or susceptible to degradation. The engine oil will eventually fail to provide these functions with possibly unrepairable damages as a result. LÄS MER

  7. 5. Screening of blood and mucus parameters towards breeding for resistance to salmon louse (lepeophtheirus salmonis) in atlantic salmon

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Das Amit; [2012]
    Nyckelord :Sea lice; parasite resistance; disease resistance; genetic variation; Atlantic salmon; Rainbow trout; biological markers;

    Sammanfattning : Over the last three decades salmon farmers have experienced serious economic hardships due to losses caused by sea lice (Lepeophtheirus salmonis) infestations. In the absence of an effective vaccine, inefficiency of biological control methods and growing concerns over the usage of chemical treatments, there is a quest for alternative strategies to combat this problem.
