    Keywords : 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;

    Abstract : 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. READ MORE

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

    University essay from Linköpings universitet/Statistik och maskininlärning

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

    Abstract : 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. READ MORE

  3. 3. A Multivariate Process Analysis on a Paper Production Process

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Jaime Löfroth; Samuel Wiklund; [2018]
    Keywords : variable selection; PLSR; multivariate process analysis; paper production;

    Abstract : A big challenge in managing large scale industry processes, like the ones in the paper and pulp industry, is to reduce the amount of downtime and reduce sources of product quality variability to a minimum, while staying cost effective. To accomplish this the key is to understand the complex nature of the processes variables, and to quantify the causal relationships between them and the product quality together with the amount of output.

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

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Matematisk statistik

    Author : Fredrik Berntsson; [2016]
    Keywords : ;

    Abstract : 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. READ MORE
