  1. 1. Microfluidic sorting of sperm for assisted reproduction - An evaluation of ZyMōt multi sperm separation device

    University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Author : Emma Olofsson; [2023-06-22]
    Keywords : Assisted reproduction technologies Spermatozoa DNA fragmentation Density-gra- dient centrifugation Microfluidics ZyMōt Multi;

    Abstract : Infertility is a worldwide problem and the main reason for the use of assisted reproductive technol- ogy (ART). In-vitro fertilization (IVF) is one ART treatment normally used, where the fertilization of oocytes occurs in vitro. READ MORE

  3. 2. Improving Machinery Safety : Modelling data to explain machine stops and developing a strategy on how to reduce them

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Kristina Leijonborg; Sandra Hammarsten; [2023]
    Keywords : ;

    Abstract : The purpose of this thesis is to examine how machinery safety at Stora Enso can be increased, with the goal of reducing the amount of machine stops and improving the operational safety within the Packaging Solutions division. To do this, data from the one of the machines at the Jönköping mill has been used for classification and time series modelling. READ MORE

  4. 3. Turbulent Boundary Layers Modelling with Deep Operator Networks

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Yu-Cheng Lu; [2023]
    Keywords : Turbulent Boundary Layers; Pressure Gradient; Composite Profiles; Deep Operator Networks; Sensitivity Analysis Nyckelord på svenska;

    Abstract : This thesis project aims to advance the modelling of pressure gradient turbulent boundary layers (PG TBLs) and offer new insights into TBLs modelling. Previous analytical studies have explored various mathematical models, but this research introduces an extended unstacked Deep Operator Networks (DeepONets) architecture with double outputs and five branch parameters.

  5. 4. Scenario Generation for Stress Testing Using Generative Adversarial Networks : Deep Learning Approach to Generate Extreme but Plausible Scenarios

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Jonas Gustafsson; Conrad Jonsson; [2023]
    Keywords : Machine Learning; Generative Adversarial Network GAN ; Wasserstein Generative Adversarial Network WGAN ; Scenario Generation; Stress Testing; Central Counterparty Clearing;

    Abstract : Central Clearing Counterparties play a crucial role in financial markets, requiring robust risk management practices to ensure operational stability. A growing emphasis on risk analysis and stress testing from regulators has led to the need for sophisticated tools that can model extreme but plausible market scenarios. READ MORE

  6. 5. Analysis of hot workability in 316L steel using ductile fracture criterions

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Viktor Strid; [2022]
    Keywords : Ductile fracture criterion; Finite Element Method; Hot working; 316L Stainless Steel; Fracture Modeling; Gleeble; Hot deformation;

    Abstract : The focus of this thesis is to develop a simulation model for predicting ductile fractures during hot working at Alleima. The main fracture mechanism in these conditions is ductile fracture by void coalescence. The ductile fractures are caused by the linking of voids that appear when there is large plastic deformation near second-phase particles. READ MORE
