  1. 1. Root-cause analysis with data-driven methods and machine learning in lithium-ion battery tests : Master's thesis about detecting deviations with PCA

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Frans Rademacher; [2022]
    Keywords : Machine learning; Li-ion; batteries; PCA; deviations; anomaly detection; root-cause analysis; differential capacity; feature engineering;

    Abstract : The increased demand of energy storage systems and electric vehicles on the market result in high demand of lithium-ion batteries. As a lithium-ion battery manufacturer, Northvolt runs quality tests on the products to assess their performance, life and safety. READ MORE

  2. 2. Multi-environment Screening of Timothy (Phleum pratense) Breeding Material for Better Forage Yield in Sweden.

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Ibrahim Issa; [2022]
    Keywords : Phleum pratense; Multi-Environment; Forage yield; Sweden; Genotype-by-environment interaction Swedish;

    Abstract : Timothy (Phleum pratense) is one of the most widely used forage crops in hay and pasture grass mixtures in Nordic countries; it’s also used in areas where it is one of the top forage crops harvested high yield, especially in boreal climates. There hasn’t been any large-scale breeding of Timothy to develop varieties that are adapted for Swedish climate and standards, which is surprising given that Timothy is the main forage crop used in Sweden.

  3. 3. Real-time unsupervised log event anomaly detection in public transportation

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Felicia Segui; Andreas Timürtas; [2022]
    Keywords : Technology and Engineering;

    Abstract : Detecting log data anomalies in real-time is useful since it makes it possible to apply logic that corrects the anomalies when they happen. This project presents a method for detecting public transportation bus event log data anomalies in realtime, without having a labeled data set. READ MORE

  4. 4. Log Anomaly Detection of Structured Logs in a Distributed Cloud System

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : David Nilsson; Albin Olsson; [2022]
    Keywords : Technology and Engineering;

    Abstract : As computer systems grow larger and more complex, the task of maintaining the system and finding potential security threats or other malfunctions become increasingly hard. Traditionally, this has had to be done by manually examining the logs. READ MORE

  5. 5. Deep learning, LSTM and Representation Learning in Empirical Asset Pricing

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Benjamin von Essen; [2022]
    Keywords : LSTM; empirical asset pricing; deep learning; representation learning; neural networks; LSTM; empirisk tillgångsvärdering; djupinlärning; representationsinlärning; neurala nätverk;

    Abstract : In recent years, machine learning models have gained traction in the field of empirical asset pricing for their risk premium prediction performance. In this thesis, we build upon the work of [1] by first evaluating models similar to their best performing model in a similar fashion, by using the same dataset and measures, and then expanding upon that.
