  1. 1. Effects of visualization using different convolution kernels in Julia

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Nils Forsberg; Axel Nilsson; [2023]
    Keywords : Convolution; Julia; visualization; streamlines; vorticity; interpolation; filter;

    Abstract : Many real-world engineering problems require large amounts of data in order to accurately model and predict outcomes. However, this data is often noisy, sampled and discontinuous, making the data difficult to process and giving rise to incorrect models. READ MORE

  3. 2. Adjoint optimization of a liquid-cooled heat sink

    University essay from KTH/Teknisk mekanik

    Author : Roven Pinto; [2023]
    Keywords : Adjoint method; topology optimization; porosity; OpenFOAM;

    Abstract : Improving the design of flow channels in a liquid-cooled heat sink is critical for boosting the capabilities of electronic components as well as reducing energy usage by the pump. This work explores the use of topology optimization to minimize the pressure difference across a heat sink and consequently, the energy used to supply the liquid. READ MORE

  4. 3. Compact Digital Track Maps: Enhancing Train Traveller Information at the Crossing of Accuracy and Availability : A comparative analysis of algorithms for generating compact representations of railway tracks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Adam Andersson; [2023]
    Keywords : Train positioning; Digital track map; Digital map generation; Position measurement; Global navigation satellite system; Cartography; Tågpositionering; Digitala spårkartor; Generering av digitala kartor; Positionsmätning; Satellitnavigation; Kartograf;

    Abstract : Trains are constrained to the railway tracks they operate on. This can be leveraged for absolute train positioning, where a train’s position can be mapped onto a digital track map (DTM). Extensive research has been dedicated to enhancing the accuracy of DTMs. READ MORE

  5. 4. Generating Extreme Value Distributions in Finance using Generative Adversarial Networks

    University essay from KTH/Matematik (Avd.)

    Author : William Nord-Nilsson; [2023]
    Keywords : Extreme Value Theory; Generative Adversarial Networks; Stress Testing; Machine Learning; Convolutional Neural Networks; evtGAN; Extreme Events; Extremvärdesteori; Generativa nätverk; Stresstestning; Maskininlärning; Djupt neuralt nätverk; evtGAN; Extrema händelser;

    Abstract : This thesis aims to develop a new model for stress-testing financial portfolios using Extreme Value Theory (EVT) and General Adversarial Networks (GANs). The current practice of risk management relies on mathematical or historical models, such as Value-at-Risk and expected shortfall. READ MORE

  6. 5. Implementation of Super-Resolution Ultrasound Imaging for in Vitro Experiments

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Kani Yara; [2022]
    Keywords : B-mode; Localization; Microbubbles; Poly-Vinyl-Alcohol; Tracking; Verasonics; B-mode; Localisering; Mikrobubblor; Poly-Vinyl-Alcohol; Spårning; Verasonics;

    Abstract : Ultrasound imaging systems are a safe and affordable imaging modality with the disadvantage of low spatial resolution, especially for assessing smaller vessels. However, with the implementation of super-resolution ultrasound imaging techniques, studies have shown promising results in achieving a resolution below the diffraction limit. READ MORE
