  1. 1. Detection of performance anomalies through Process Mining

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

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

    Abstract : 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.

  3. 2. Data Fusion and Text Mining for Supporting Journalistic Work

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Vermes Zsombor; [2022]
    Keywords : text mining; data fusion; algorithmic journalism; computational journalism; keyword extraction; named entity recognition; sentiment analysis; fake news classification;

    Abstract : During the past several decades, journalists have been struggling with the ever growing amount of data on the internet. Investigating the validity of the sources or finding similar articles for a story can consume a lot of time and effort. These issues are even amplified by the declining size of the staff of news agencies. READ MORE

  4. 3. Designing an algorithm to build communities by combining semi-cliques spanning multiple graphs

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Tyson McLeod; [2021]
    Keywords : ;

    Abstract : Community detection is an important graph mining task and one of the most researched problems in its field of study. One reason for this is its applicability in a variety of disciplines ranging from biology to computer science. READ MORE

  5. 4. The Kiruna town move : Unearthing the possibilities for full-scale fire tests

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Henrik Pettersson; Adam Thörn; [2021]
    Keywords : Full-scale fire tests; Kiruna town move; SFPE roadmap; Fire tests; Kiruna s housing-stock; Fullskaliga brandförsök; Kiruna stadsflytt; Brandförsök; Kirunas Byggnadsbestånd;

    Abstract : The work with this thesis started during the last semester at the Fire Protection Engineering program at Luleå University of Technology. Kiruna has relied on the iron ore resources of Luossavaara and Kiirunavaara since the creation of the town. The iron ore stretches underneath the current city center. READ MORE

  6. 5. Run-time Anomaly Detection with Process Mining: Methodology and Railway System Compliance Case-Study

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Francesco Vitale; [2021]
    Keywords : Anomaly Detection; Autonomous Maintenance; Cyber-Physical Systems; Internet of Things; Data science; Process science; Process Mining; Conformance Checking; ERTMS ETCS;

    Abstract : Detecting anomalies in computer-based systems, including Cyber-Physical Systems (CPS), has attracted a large interest recently. Behavioral anomalies represent deviations from what is regarded as the nominal expected behavior of the system. Both Process science and Data science can yield satisfactory results in detecting behavioral anomalies. READ MORE
