  1. 1. Gate driver solutions for high power density SMPS using Silicon Carbide MOSFETs

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Farhan Akram; [2021]
    Keywords : SiC MOSFETs; Gate drivers; DC-DC converter; High power and efficiency power supplies;

    Abstract : Discrete silicon carbide (SiC) power devices have unique characteristics that outpace those of silicon (Si) counterparts. The improved physical features have provided better faster switching, greater current densities, lower on-resistance, and temperature performances. READ MORE

  2. 2. Pre-planning of Individualized Ankle Implants Based on Computed Tomography - Automated Segmentation and Optimization of Acquisition Parameters

    University essay from KTH/Fysik

    Author : Matilda Engström Messén; Elvira Moser; [2021]
    Keywords : osteochondral lesions of the talus; computed tomography; U-net; convolutional neural network; dice coefficient; fotled; ledbrosk; osteochondral lesion of the talus; datortomografi; U-net; convolutional neuralt nätverk; dicekoefficient;

    Abstract : The structure of the ankle joint complex creates an ideal balance between mobility and stability, which enables gait. If a lesion emerges in the ankle joint complex, the anatomical structure is altered, which may disturb mobility and stability and cause intense pain. READ MORE

  3. 3. Stickering of Food Products at IKEA – Improving a Process Through Learning from Others

    University essay from Lunds universitet/Teknisk logistik

    Author : John Nyqvist; Victoria Vernet; [2021]
    Keywords : Stickering; labelling; packaging information requirements; food supply chain; process maturity; Technology and Engineering;

    Abstract : Title: Stickering of Food Products at IKEA–Improving a Process Through Learning from Others; Increasing process maturity to ensure future performance Authors: John Nyqvist and Victoria Vernet Supervisors: Eva Berg, Department of Industrial Management and Logistics, Faculty of Engineering, Lund University Problem description: Stickering has been used at IKEA for a long time to create compliant food products on markets where volumes are too low. Low volumes make it economically challenging to create compliant artworks and to produce large enough batches to meet cost requirements. READ MORE

  4. 4. Transient Waveform Clustering : Developing efficient data analytics toolchains applying unsupervised machine learning techniques on power quality events

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Albert Varghese Rajan; [2021]
    Keywords : HVDC; Power Quality; Machine Learning; Autoencoder; Clustering; Monitoring and analytics;

    Abstract : High Voltage Direct Current (HVDC) transmission systems appropriate for bulk power transfer to meet increasing power demands and ideal for interconnecting power systems with distant renewable sources of energy without any chances of loss synchronism, efficiency, and reliability. The main obstacle is however connected with the DC grid protection where the timely diagnosis of faults is critical to prevent any rapid built-up leading to failure of the power electronic devices.

  5. 5. Pitcher : An automatic guitar tuner

    University essay from KTH/Mekatronik; KTH/Mekatronik

    Author : Hannes Andersson; John Sjöberg; [2021]
    Keywords : Arduino; mechatronics; autocorrelation; guitar tuner; pitch detection algorithm; Arduino; mekatronik; autokorrelation; gitarrstämmare; tonavläsning;

    Abstract : Pitcher is a prototype which makes it easier for inexperienced guitar players to tune their guitars without any prior knowledge required. This thesis will explore how the construction varies between the usage of DC and a stepper motor, how reliable the tuner is and how long it takes to tune the guitar. READ MORE
