  1. 21. Machine learning for risk ranking of component failure : A comparative study of traditional- and survival machine learning approaches applied to historical data

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Datalogi

    Författare :Fredrik Nilsson; Fanny Fristedt; [2023]
    Nyckelord :Machine learning; Survival analysis; Trains; Freight trains; Damage prediction; Maskininlärning; överlevnadsanalys; tåg; godståg; Skadeprediktion;

    Sammanfattning : This master thesis investigates the use of machine learning for predicting and assessing the risk of railway vehicle component failures. Data used for failure prediction often comes with limitations due to the complex nature of maintenance or sometimes requires investments for the extraction of information. LÄS MER

  3. 22. Data Analysis for Predictive Maintenance of a Straightening Machine in the Steel Industry

    Magister-uppsats, Högskolan i Gävle/Elektronik

    Författare :Paul Barron; [2023]
    Nyckelord :Condition Monitoring; Features; Clustering;

    Sammanfattning : The availability of industrial machinery is crucial to any business operating in the manufacturingsector. Mechanical failures halt production and unplanned downtime canbe disruptive and costly. Small failures can compound to serious failures which exponentiallyincreases downtime and repair costs.

  4. 23. Practical Analysis of the Giskard Consensus Protoco

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Leon Sandner; [2023]
    Nyckelord :Distributed Ledger; Blockchain; Consensus Protocol; Giskard; Hyperledger Sawtooth; Distribuerade Huvudbok; Blockchain; Konsensus; Giskard; Hyperledger Sawtooth;

    Sammanfattning : Consensus protocols are the core of modern blockchain systems, such as the Bitcoin, Ethereum, and Algorand networks. Thanks to these protocols, participants in a blockchain network can reach consensus on which blocks to add to a blockchain, to have a consistent chain of blocks in the whole network. LÄS MER

  5. 24. Loyalty Program Termination Recovery - A quantitative study on the efficacy of compensation and explanation recovery efforts in mitigating negative reactions following a loyalty program termination

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för företagande och ledning

    Författare :Marcus Hagström; Karl Granbom; [2023]
    Nyckelord :Loyalty program termination; Service failure; Recovery efforts; Compensation; Explanation;

    Sammanfattning : Loyalty program (LP) practitioners increasingly face the necessity to terminate their LP considering the disadvantages to LP management, the fact that LPs continually fail to be of value to many members and the growing shift towards subscription-based loyalty models. Aware that terminations lead to negative customer reactions, managers will inevitably wonder how to mitigate such reactions so as to retain customers and diminish negative backlash. LÄS MER

  7. 25. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Carl Holmquist; [2023]
    Nyckelord :Physical Geography and Ecosystem analysis; LPJ-GUESS; drought; sensitivity analysis; evapotranspiration; gross primary production; hydraulic parameters; boreal forest.; Earth and Environmental Sciences;

    Sammanfattning : Drought is projected to increase in frequency and intensity and impacts trees with increased water stress and increased mortality rate. Water stresses can cause hydraulic failure-related mortality or carbon starvation due to tree species having different strategies to deal with water stresses. LÄS MER
