  1. 1. Heart- and Sapwood Segmentation on Hyperspectral Images using Deep Learning

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Samuel Hallin; Simon Samnegård; [2023]
    Nyckelord :Computer Vision; Hyperspectral Imaging; Heartwood; Sapwood; Deep Learning; Segmentation; Dimensionality Reduction; PCA; PLS; SVM; U-NET; U-within-U-Net;

    Sammanfattning : For manufacturers in the wood industry, an important way to make the production more effective is to automate the process of detecting defects and different attributes on boards. One important attribute on most boards is heartwood and sapwood. LÄS MER

  2. 2. Multivariate Data Analysis on (Ti,Al)N Arc-PVD coating process : MVDA of the growth parameters thickness, stress,composition, and cutting performance

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Oorganisk kemi

    Författare :Per-Olof Öqvist; [2021]
    Nyckelord :chemistry; material; coating; statistics; PLS; PCA; kemi; material; beläggning; statistik; PLS; PCA;

    Sammanfattning : This diploma work was done at Seco Tools AB (SECO) in Fagersta and aimed to evaluate the possibility to model the relationship between deposition data, deposition properties and, cutting performance of a (Ti,Al)N coating on cutting inserts by applying the Multivariate Data Analysis (MVDA) modeling technique Partial Least Squares Projection to Latent Structures Modeling (PLS). Cathodic Arc Deposition (Arc-PVD) was the PVD technique focused on this study. LÄS MER

  3. 3. Evaluation of Novel Quality Control Methods for Wheat Flour

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Josefine Dahlman; Stephanie Laurent Hedlund; [2021]
    Nyckelord :Wheat flour; Quality control; PCA; PLS; Alveolab; Rheo F4; Mixolab; Food technology; Technology and Engineering;

    Sammanfattning : The quality of a flour can vary greatly depending on the wheat variety and on the conditions while growing the wheat. Currently, the quality is mainly assessed by test baking the flour to observe the volume of the final product. LÄS MER

  4. 4. Toward predictive maintenance in surface treatment processes : A DMAIC case study at Seco Tools

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Martin Berg; Albin Eriksson; [2021]
    Nyckelord :Predictive maintenance; Industry 4.0; Data-driven maintenance; chemical vapour deposition; wet blasting;

    Sammanfattning : Surface treatments are often used in the manufacturing industry to change the surface of a product, including its related properties and functions. The occurrence of degradation and corrosion in surface treatment processes can lead to critical breakdowns over time. LÄS MER

  5. 5. Development of a Near Infrared Spectroscopy Model for Prediction of Fibre Compounds in Alfalfa

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Christina Andersen; [2020]
    Nyckelord :alfalfa; lucerne; medicago sativa; green protein powder; NIR; near infrared spectroscopy; model development; matlab; PLS; partial least squares; PCA; principal component analysis; SNV; standard normal variate; fibre prediction; TDF; total dietary fibre; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Sammanfattning : Background: This project investigates if it is possible to develop a calibration model from near infrared (NIR) spectroscopic measurements, for determination of the amount and type of fibre fractions within protein powder produced from the legume alfalfa, without performing wet experiments. Alfalfa is also known as Medicago sativa and lucerne, but is in this project further referred to as alfalfa. LÄS MER
