  1. 26. Detection of performance anomalies through Process Mining

    Master-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :Carmine Marra; [2022]
    Nyckelord :Process mining; Conformance Checking; performance anomalies; ERTMS ETCS; Railway system; complex computer systems.;

    Sammanfattning : Anomaly detection in computer systems operating within complex environments,such as cyber-physical systems (CPS), has become increasingly popularduring these last years due to useful insights this process can provide aboutcomputer systems’ health conditions against known reference nominal states.As performance anomalies lead degraded service delivery, and, eventually,system-wide failures, promptly detecting such anomalies may trigger timelyrecovery responses.

    Sammanfattning : The number of IoT and cyber-physical systems will be growing in the comingfuture. According to estimates, more than 21 billion IoT devices are expectedto exist by 2025. The adoption of Digital Twins and AI-enhanced IoTapplications is projected to fuel the expected increase in IoT spending.It is essential to accelerate the development. LÄS MER

  5. 29. Systematic Literature Review of the Adversarial Attacks on AI in Cyber-Physical Systems

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :Nail Valeev; [2022]
    Nyckelord :Adversarial attacks; machine learning; artificial intelligence; cyber-physical system; internet of things;

    Sammanfattning : Cyber-physical systems, built from the integration of cyber and physical components, are being used in multiple domains ranging from manufacturing and healthcare to traffic con- trol and safety. Ensuring the security of cyber-physical systems is crucial because they provide the foundation of the critical infrastructure, and security incidents can result in catastrophic failures. LÄS MER

  7. 30. Identifying Machine States and Sensor Properties for a Digital Machine Template : Automatically recognize states in a machine using multivariate time series cluster analysis

    Uppsats för yrkesexamina på avancerad nivå, Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Författare :Jakob Viking; [2021]
    Nyckelord :Digital twin; Digital shadow; Unsupervised learning; Cluster analysis; HDBSCAN; Chi-squared goodness of fit test;

    Sammanfattning : Digital twins have become a large part of new cyber-physical systems as they allow for the simulation of a physical object in the digital world. In addition to the new approaches of digital twins, machines have become more intelligent, allowing them to produce more data than ever before. LÄS MER
