    Sammanfattning : Abstract Title: Purchasing and digitalization in an era of turbulence Authors: Emil Sarajlic & Vishal Natesan Supervisor: Wilbert Baerwaldt, Director Sourcing and Value Chain at Duni AB Louise Bildsten, Department of Industrial Management & Logistics, Faculty of Engineering, Lund University Examiner: Jan Olhager, Department of Industrial Management & Logistics, Faculty of Engineering, Lund University Background: This research delves into the uncertainties and challenges encountered in global supply chain operations, exacerbated by unpredictable events such as the COVID-19 pandemic and the 2021 Suez Canal obstruction. These disruptions can lead to stock-outs, poor capacity utilization, and the need for expensive buffers. LÄS MER

  4. 3. Utvärdering av en befintlig plattform för neurofeedback med hjälp av open-source EEG

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Hakim Al Kouatli; Mohamed Achmawi; [2022]
    Nyckelord :OpenBCI; Neurofeedback; concentration; relaxation; open-source.; OpenBCI; Neurofeedback; concentration; avslappning; open-source.;

    Sammanfattning : Neurofeedback is a type of biofeedback in which subjects learn to use the activity of their own electrical brain waves to respond to a visual or auditory feedback from the activity of the brain. This is done by connecting electrodes to the body to get the brain's electrical activity in the form of encephalogram signals (EEG) which are then calculated and converted into useful feedback.

  5. 4. Surface Functionalization of Nanowires Using Silane-PEG Compounds

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

    Författare :Hedvig Ekfors Elvin; [2022]
    Nyckelord :Functionalization; Nanowires; Silanization; Surface Chemistry; Materials Chemistry; Chemistry;

    Sammanfattning : Introduction: GaP nanowires were functionalized using silane-PEG-NH2 and compared with cellulose acetate, PAcrAm™-g-(PMOXA, amine, silane) and a non-functionalized reference sample. Functionalization would allow strong, covalent anchoring of antibodies instead of adsorption. LÄS MER

  7. 5. Classification of a Sensor Signal Attained By Exposure to a Complex Gas Mixture

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Rabnawaz Jan Sher; [2021]
    Nyckelord :Classification; Random Forest; Linear Discriminant Analysis; Naive Bayes; Principal Component Analysis; Drift; Baseline Compensation; Normalization; Sensor; Signal Preprocessing.;

    Sammanfattning : This thesis is carried out in collaboration with a private company, DANSiC AB This study is an extension of a research work started by DANSiC AB in 2019 to classify a source. This study is about classifying a source into two classes with the sensitivity of one source higher than the other as one source has greater importance. LÄS MER
