  1. 1. A Machine Learning-Based Approach for Fault Detection of Railway Track and its Components

    University essay from Luleå tekniska universitet/Drift, underhåll och akustik

    Author : Johnny Asber; [2020]
    Keywords : Condition Based Maintenance in Railway; Machine Learning; Deep Learning; ResNet-50;

    Abstract : The hard equation of railway safety versus the high commercial profits can only be achieved through the use of new inspection methods supported by modern technologies. The track and its components can have different types of troubles, such as rail surface defects, broken sleepers, missing fasteners, and irregular ballast levels. READ MORE

  3. 2. Development and initial validation of a stochastic discrete event simulation to assess disaster preparedness

    University essay from Linköpings universitet/Interaktiva och kognitiva system

    Author : Mattias Lantz Cronqvist; [2018]
    Keywords : ;

    Abstract : Assessing disaster preparedness in a given region is a complex problem. Current methods are often resource intensive and may lack generalizability beyond a specific scenario. Computer-based stochastic simulations may be an additional method but would require systems that are valid, flexible and easy-to-use. READ MORE

  4. 3. Robust design of bridges : robustness analysis of Sjölundaviadukt bridge

    University essay from Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Ìvar Björnsson; [2010]
