  1. 1. Predictive Modeling of Pipetting Dynamics. Multivariate Regression Analysis: PLS and ANN for Estimating Density and Volume from Pressure Recordings

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Lisa Linard Pedersen; [2024]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Thermo Fisher Scientific manufacture automatic pipetting instruments for diagnostic tests. These tests are sensitive to abnormalities and changes in e.g. volume or density could potentially lead to less precision or other issues in the pipetting work flow. LÄS MER

  3. 2. Magnetic field separation for current prediction in three-phase systems : Regression-based current prediction

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Sara Lenman; Sofia Blaad; [2023]
    Nyckelord :Alternating Current; Crosstalk Separation; Magnetic field sensors; Regression; Sensor technology; Three-phase system;

    Sammanfattning : Current controls the motion of a manipulator. The manipulators at ABB are powered by a three-phase alternating current system where shunt resistors are utilised to measure the current to the motors. Magnetic field sensors are instead investigated to eliminate issues with power losses, the number of components and the cost of the shunt resistors. LÄS MER

  4. 3. Automatic analysis of tool status in band saws

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Axel Östman; [2022]
    Nyckelord :;

    Sammanfattning : The products with the highest return and longest life cycle in the sawmill industry are boards and planks. Unfortunately, a large part of the log becomes bi-products during the cutting process. One way to reduce the amount of bi-products in a sawline is to saw with as thin kerfs as possible. That is the cut of the blade. LÄS MER

  5. 4. Using Sentinel-2 Satellite Images to Estimate Traits of Forage Grasslands

    Master-uppsats, SLU/Dept. of Agricultural Research for Northern Sweden

    Författare :Niklas Zeiner; [2021]
    Nyckelord :Remote sensing; Forage grasslands; Sentinel-2; Dry matter yield; Canopy average height; Total leaf chlorophyll content; Partial least squares; Support vector machines;

    Sammanfattning : In this project, regression models based on data from field measurements and spectral information extracted from satellite imagery were used to estimate traits of forage grasslands; dry matter yield, canopy average height and total leaf chlorophyll. Four fields at SLUs Röbäcksdalen field station were sampled on 22 occasions and a total of 198 samples, including measurement of the highest plant, canopy height, leaf chlorophyll content, canopy spectral reflectance and biomass were collected.

  7. 5. 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
