  1. 11. Volumetric Image Segmentation of Lizard Brains

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Yulia Dragunova; [2023]
    Nyckelord :image segmentation; deep learning; atlas; lizard brain; micro-CT; image augmentation; bild segmentering; djupinlärning; atlas; ödelhjärna; mikro-datortomagrofi; datautökning;

    Sammanfattning : Accurate measurement brain region volumes are important in studying brain plasticity, which brings insight into the fundamental mechanisms in animal, memory, cognitive, and behavior research. The traditional methods of brain volume measurements are ellipsoid or histology. LÄS MER

  3. 12. Verifiering av ny extraktionsmetod för analys på oljeindex

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Theodor Hägglund; [2023]
    Nyckelord :metodverifiering; oljeindex; gaskromatografi; extraktion;

    Sammanfattning : Huvudsyftet med detta examensarbete var att verifiera en ny metod för extraktion av olja från jord-, slam-, och sedimentprover som ska ersätta företagets befintliga metod. Extraktionen sker på ett skakbord som förbehandling innan den extraherade oljan sätts på en GC-FID för att analysera dess oljeindex mellan C10-C40 samt dess olika specifika delfraktioner. LÄS MER

  4. 13. Optimization of two high-performance size-exclusion chromatography methods with diode-array detection for protein quantification and purity assessment

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Camilla Lane; [2023]
    Nyckelord :Method qualification; Protein concentration; Protein Purity; High Performance Size exclusion chromatography; Quality control; Analytical chemistry; Biology and Life Sciences;

    Sammanfattning : Background: There is a need to develop methods of determining concentration and purity for two new affinity ligands, protein T and protein H, in order to ensure the quality of an industrial production of said proteins. Aims: To develop a High Performance Size Exclusion Chromatography, HPSEC, method to determine concentration and purity of protein T and to improve an existing HPSEC method for concentration and purity determination of protein H that show selectivity, display linearity between peak area and injection amount and give repeatable results.

  5. 14. Hardware in Loop Simulations of Electric Drives

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

    Författare :Varad Deshpante; [2023]
    Nyckelord :Electric Machines; Electronic Control Unit; Inverter; Field Programmable Gate Array; Hardware in the Loop; Software in the Loop; Elektriska Maskiner; Elektronisk Styrenhet; Växelriktare; Programmerbar Integrerad Krets; Hårdvara i Loop; Programvara i Loop;

    Sammanfattning : Electric drives are crucial components of powertrain of modern vehicles. They need to be controlled effectively to deliver a comfortable and efficient driving experience. The control unit needs to be robust to handle extreme operating conditions and faults in a safe manner. LÄS MER

  7. 15. The Effects of Material Properties in Saw Chain Cutting Efficiency Tests : Investigating the repeatability of cutting efficiency tests

    Master-uppsats,

    Författare :Petter Ödvall; Jakob Ivarsson; [2023]
    Nyckelord :Alternative Material; Cutting Efficiency; Density; Hardness; Knots; Moisture Content; Pinus Sylvestris; Polyethylene; Regression Model; Saw Chain;

    Sammanfattning : Manufacturers of saw chains continuously strive to increase the performance of their products by reducing cutting times and minimising the energy consumption required for cutting. However, the evaluation process through testing is problematic as several uncontrollable factors impact the results. LÄS MER
