  1. 6. Offshore wind to hydrogen for powering port land mobility : Case study in Port of Valencia.

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Jose Luis Blay Pomar; [2022]
    Keywords : wind-to-hydrogen; port land mobility; Port of Valencia; hydrogen;

    Abstract : Maritime cargo transport is a major energy consumer and polluting sector, accounting for 90% of world trade in goods and responsible for 2.5% of global greenhouse gas emissions per year. READ MORE

  3. 7. Prognostics for Condition Based Maintenance of Electrical Control Units Using On-Board Sensors and Machine Learning

    University essay from Linköpings universitet/Fordonssystem

    Author : Gabriel Fredriksson; [2022]
    Keywords : machine learning; random forest; random survival forest; condition based maintenance; cbm; reliability; solder joint failure; thermomechanical cycling; ECU; lifetime prediction; data-driven; statistics; BGA; PCBA; field quality; maintenance; truck; bus; vehicle;

    Abstract : In this thesis it has been studied how operational and workshop data can be used to improve the handling of field quality (FQ) issues for electronic units. This was done by analysing how failure rates can be predicted, how failure mechanisms can be detected and how data-based lifetime models could be developed. READ MORE

  4. 8. Approximation of General Semi-Markov Models Using Expolynomials

    University essay from KTH/Matematisk statistik

    Author : Niklas Nyholm; [2021]
    Keywords : applied mathematics; Markov modelling; Semi-Markov process; approximation theory; expolynomial; phase-type distribution; reliability analysis; tillämpad matematik; Markov modellering; Semi-Markov process; approximations teori; expolynom; phase-type fördelning; riskanalys;

    Abstract : Safety analysis is critical when developing new engineering systems. Many systems have to function under randomly occurring events, making stochastic processes useful in a safety modelling context. However, a general stochastic process is very challenging to analyse mathematically. READ MORE

  5. 9. Evaluating the onshore wind power potential of Gotland using the New European Wind Atlas

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Andres Arteaga Ossa; [2021]
    Keywords : ;

    Abstract : The island of Gotland has played an important role in the history of wind energy in Sweden since the very beginning. In the past decade, the island reached the maximum intermittent wind power capacity that the local grid and the current connection to the mainland can safely manage without compromising the security of supply.

  6. 10. Combining scientific computing and machine learning techniques to model longitudinal outcomes in clinical trials.

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Harshavardhan Subramanian; [2021]
    Keywords : Bootstrap sampling; Cubic spline interpolation; Sparse regression; SINDy; Bayesian inference; Mechanistic Modeling; Scientific computing;

    Abstract : Scientific machine learning (SciML) is a new branch of AI research at the edge of scientific computing (Sci) and machine learning (ML). It deals with efficient amalgamation of data-driven algorithms along with scientific computing to discover the dynamics of the time-evolving process. READ MORE
