1. 1. Remaining Useful Life Prediction of Power Electronic Devices Using Recurrent Neural Networks

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

   Författare :Congrui Cai; [2023]
   Nyckelord :Power electronics; Prognostics and health management; Remaining useful life; Recurrent neural network; Kraftelektronik; Prognostik och hälsoledning; Återstående livslängd; Återkommande neurala nätverk;

   Sammanfattning : The growing demand for sustainable technology has led to an increased application of power electronics. As these devices are often exposed to harsh conditions, their reliability is a primary concern for both manufacturers and users. LÄS MER

3. 2. Convolutional-LSTM for IGBTs Prognostics and Age Monitoring : Designing a neural network for predicting aging precursors in power devices

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

   Författare :Matteo Santoro; [2023]
   Nyckelord :Neural Networks; Igbt; Prognostics; Age Monitoring; Neurala Nätverk; Igbt; Prognostik; Övervakning av Ålder;

   Sammanfattning : In recent years, extensive research efforts have been dedicated to the field of prognostics and age-related degradation, with major focus on higher complexity devices. However, relatively little attention has been given to power devices, such as Insulated Bipolar Gate Transistors (IGBTs), despite their critical role in high power electronic applications. LÄS MER

4. 3. Den unga kvinnans upplevelser av att leva med bröstcancer : En litteraturöversikt

   Kandidat-uppsats, Röda Korsets Högskola

   Författare :Mast Nareman Nasradin; Siham Belajouza; [2022]
   Nyckelord :Breast cancer; Experience; Women; Young; Bröstcancer; Kvinnor; Ung; Upplevelse;

   Sammanfattning : Bakgrund: Bröstcancer är idag den vanligaste cancerformen som drabbar kvinnor i världen. För unga kvinnor under 45 årsåldern riskerar endast 4-6% att drabbas av bröstcancer vilket utgör diagnosen till en ovanlig sjukdom. LÄS MER

5. 4. Machinery Health Indicator Construction using Multi-objective Genetic Algorithm Optimization of a Feed-forward Neural Network based on Distance

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

   Författare :Jacob Nyman; [2021]
   Nyckelord :Prognostics; Health Indicator Construction; Remaining Useful Life Prediction; Multi-objective Optimization; Distance; Prognostik; Hälsoindikatorkonstruktion; Återstående Livslängd; Multiobjektiv Optimering; Avstånd;

   Sammanfattning : Assessment of machine health and prediction of future failures are critical for maintenance decisions. Many of the existing methods use unsupervised techniques to construct health indicators by measuring the disparity between the current state and either the healthy or the faulty states of the system.

7. 5. Method development for enrichment of autoantibodies from human plasma

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Lovisa Skoglund; [2020]
   Nyckelord :autoantibodies; enrichment; autoimmunity; plasma; suspension bead array; autoantikroppar; anrikning; autoimmunitet; plasma; suspension bead array;

   Sammanfattning : Antibodies are naturally occurring in humans, with the function to protect the body from pathogens. Occasionally, antibodies towards the body’s own proteins are produced. These so called autoantibodies are present in healthy individuals but are also highly associated with diseases with autoimmune involvement. LÄS MER
