  1. 6. CHILLER DIAGNOSTICS Machine learning approach Carrier

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Vilius Koegst; Tatiana Orlova; [2022]
    Keywords : Technology and Engineering;

    Abstract : Chillers are large and complex machines that are used for temperature regulation in large buildings and plants. An undetected fault in the machine can lead to extended downtime and cause both great financial losses and increased environmental impact. READ MORE

  3. 7. Using Machine Learning for Predictive Maintenance in Modern Ground-Based Radar Systems

    University essay from KTH/Matematisk statistik

    Author : Dina Faraj; [2021]
    Keywords : Predictive Maintenance; Machine learning; Isolation forest; K-means clustering; Logistic regression; Radar systems.; Prediktivt underhåll; Maskininlärning; Isolation forest; K-means klustring; Logistisk regression; Radarsystem.;

    Abstract : Military systems are often part of critical operations where unplanned downtime should be avoided at all costs. Using modern machine learning algorithms it could be possible to predict when, where, and at what time a fault is likely to occur which enables time for ordering replacement parts and scheduling maintenance.

  4. 8. Evaluation of model-based fault diagnosis combining physical insights and neural networks applied to an exhaust gas treatment system case study

    University essay from Linköpings universitet/Fordonssystem

    Author : Björn Kleman; Henrik Lindgren; [2021]
    Keywords : model-based; fault diagnosis; neural networks; data-driven; Hybrid; SCR; exhaust gas treatment system; recurrent neural networks; grey-box; heavy duty truck; fault isolation; fault detection; diagnosis; urea; machine learning; Scania; structural model; MSO; residual; Fault Diagnosis Toolbox;

    Abstract : Fault diagnosis can be used to early detect faults in a technical system, which means that workshop service can be planned before a component is fully degraded. Fault diagnosis helps with avoiding downtime, accidents and can be used to reduce emissions for certain applications. READ MORE

  5. 9. Fault Detection in Mobile Robotics using Autoencoder and Mahalanobis Distance

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Christian Mortensen; [2021]
    Keywords : Fault Detection; Anomaly Detection; Fault Isolation; Autoencoder; Mahalanobis Distance; Mobile Robotics; Mobile Robot; Robotics; Neural Network; ANN; Anomaly Score; ROS;

    Abstract : Intelligent fault detection systems using machine learning can be applied to learn to spot anomalies in signals sampled directly from machinery. As a result, expensive repair costs due to mechanical breakdowns and potential harm to humans due to malfunctioning equipment can be prevented. READ MORE

  6. 10. Diagnostics of Intermittent Errors

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Niklas Lindborg; [2021]
    Keywords : Intermittent errors; diagnostics; knowledge gap; fault isolation; Intermittenta fel; diagnostik; kunskapslucka; felisolering;

    Abstract : Intermittent faults/errors are infamous for being among the most challenging errors to diagnose. It is estimated that more than 80% of the total number of errors in real systems are intermittent errors. Previous research on intermittent errors suggests that they are the prelude to permanent faults. READ MORE
