  1. 1. Structural analysis of HZO thin film and electrode using X-ray diffraction

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Elliot Winsnes; [2024]
    Keywords : HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

    Abstract : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. READ MORE

  2. 2. Vehicle dynamics modelling of electromagnetic suspensions for MAGLEV applications

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Léa Chatelais; [2024]
    Keywords : MAGLEV; Dynamics; Requirements; Suspension; Vehicle modeling; MATLAB; MAGLEV; Dynamisk; Fordran; Upphängning; Fordon modell; MATLAB;

    Abstract : MAGnetic LEVitation Guidance System (MAGLEV) technology was commercially introduced relatively recently in the guided transport field. It is based on removing the wheels and rails of classic railway systems and supporting and guiding the train with magnets and magnetic forces instead. READ MORE

  3. 3. Despeckling Echocardiograms Using Generative Adversarial Networks

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Falk DIppel; [2023-10-23]
    Keywords : Generative adversarial network; deep learning; echocardiography; speckle noise; denoising; segmentation;

    Abstract : Previous research had shown that generative adversarial networks (GANs) are capable of despeckling echocardiograms (echos) through image-to-image translation in real-time once trained. However, only limited information regarding the quality of denoised echos and explainability of useful GAN components is provided. READ MORE

  4. 4. Compression of Sequential Voxel Data for Sequence-based Animation

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Filip Antonijevic; [2023-10-23]
    Keywords : voxel; octree; grid; compression; animation; spatiotemporal; sorting; reordering; DXT; HSV;

    Abstract : This thesis presents a method for lossy compression of voxel data in an animation sequence. Uncompressed voxel animation can become very memory intensive and therefore need a more efficient method to store and render such data. READ MORE

  5. 5. IMPLICATION FOR THE UNIVERSITY OF GOTHENBURG TO ALIGN WITH THE GOVERNMENT’S TARGET REGARDING CLIMATE NEUTRALITY BY 2045 - Scenarios and Consequences

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Nafiseh Kazemi Ashtiani; [2023-06-21]
    Keywords : Climate Neutrality; GHG emissions; higher education institutions HEIs ; Net Zero emission; carbon footprint; carbon capture and storage CCS ;

    Abstract : It is widely acknowledged that one of the most significant global challenges of the 21 st century is climate change. In its Fifth Assessment Report (2014), the Intergovernmental Panel on Climate Change (IPCC) described the present extent of the problem and the hazards involved, citing greenhouse gas emissions from human activities as the primary contributor to global warming since the mid-20th century.
