  1. 1. Numerical modeling of airflow on the cathode-side of a bipolar flow plate : How the formed geometry affects the pressure drop and flow distribution in a hydrogen fuel cell

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Olivia Johansson; [2023]
    Nyckelord :Performance; Cross-sectional geometry; Computational fluid dynamics;

    Sammanfattning : Climate change and rising temperatures is a well-known problem. To tackle global warming a transition from fossil fuels to renewable and reliable energy sources is necessary. Hydrogen, in fuel cells, is proposed to replace diesel and gasoline in the transport sector. LÄS MER

  3. 2. Applicability of Graph Neural Networks to predict Human variability in Human Body Model Rib Strain Predictions

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Statistik, AI och data science

    Författare :Julia Solhed; [2022]
    Nyckelord :Graph Neural Networks; Human Body Model; SAFER HBM; HBM simulation; Rib strain predictions; Rib fracture risk predictions;

    Sammanfattning : Finite element human body models have in recent years become widely used in the area of vehicle safety evaluations. They make it possible to predict injury risk in specific areas, down to the organ level in the human body. An existing human body model, SAFER HBM includes a rib cage representing an average male.

  4. 3. Subject-specific image analysis and computational modelling of the human Achilles tendon

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Johanna Panzar; Erika Thörn; [2021]
    Nyckelord :image analysis; Achilles tendon; FE model; biomechanics; CT image; Technology and Engineering;

    Sammanfattning : Achilles tendon rupture is becoming more prevalent with an increasing population of middle aged people participating in recreational sports. A torn Achilles tendon will likely not regain its original function, and it is unknown what treatment options are optimal. LÄS MER

  5. 4. Carbon fibre reinforced plastic energy absorbing structures under crash loads : Numerical simulations validated with experimental tests

    Master-uppsats, Luleå tekniska universitet/Materialvetenskap

    Författare :Alisanne Maria Veltman; [2019]
    Nyckelord :composites; crash; abaqus; czone;

    Sammanfattning : The development of a numerical modelling approach for carbon bre reinforced plastic energy absorbing structures designed for crash events using Abaqus/CZone is described within this master thesis. Several crash tube series have been designed, manufactured, and tested with a rather unconventional cross-sectional geometry. LÄS MER

  7. 5. A Study of Vascular Plaque in the Carotid

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Victor Thun; Kristin Salmi; [2018]
    Nyckelord :;

    Sammanfattning : In 2015, cardiovascular diseases caused the death of 17.7 million people - 31 % of all deaths globally - making it deadlier than any other cause.Cardiovascular diseases often result from Arteriosclerosis, a disease where plaque builds up and clogs arteries. LÄS MER
