  1. 1. Battery Degradation and Health Monitoring in Lithium-Ion Batteries: An Evaluation of Parameterization and Sensor Fusion Strategies

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Simon Saber; [2024]
    Keywords : model-based diagnostics; modellbaserad diagnostik;

    Abstract : The purpose of this project was to perform model-based diagnosis on Li-ion batteries using real-world data and sensor fusion algorithms. The data used in this project was collected and distributed by NASA and mainly consists of voltage and current measurements collected on numerous batteries that were repeatedly charged and discharged from their beginning of life, and until surpassing their end of life.

  3. 3. Machine learning methods for seasonal allergic rhinitis studies

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Zijie Feng; [2021]
    Keywords : Machine learning; Seasonal allergic rhinitis; Random forest; Partial least squares discriminant analysis; Bootstrap; Cubic smoothing splines; Single-cell RNA sequencing;

    Abstract : Seasonal allergic rhinitis (SAR) is a disease caused by allergens from both environmental and genetic factors. Some researchers have studied the SAR based on traditional genetic methodologies. As technology develops, a new technique called single-cell RNA sequencing (scRNA-seq) is developed, which can generate high-dimension data. READ MORE
