  1. 1. Tracing Tempera through Time-of-Flight Secondary Ion Mass Spectrometry Analysing samples from four icons from the Nationalmuseum collection

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Nina Olivier; [2024-01-30]
    Keywords : Icons; tempera; emulsions; analysis methods; ToF-SIMS;

    Abstract : This thesis will analyze samples in form of cross-sections taken from four icons of the Nationalmuseum collection, two Russian, from the 18th and 19th centuries and two Greek, also from the 18th and 19th centuries, using the Time-of-Flight Secondary Ion Mass Technique. The objective is to detect, isolate and, if possible, identify the amino acids and the fatty acids in the protein and lipids used in the tempera, the ground, and the olifa using Time of Flight Secondary Ion Mass Spectrometry.

  2. 2. Using Synthetic Data For Object Detection on the edge in Hazardous Environments

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Faraz Azarnoush; Damil Sabotic; [2024]
    Keywords : Technology and Engineering;

    Abstract : This thesis aims to evaluate which aspects are important when generating synthetic data with the purpose of running on a lightweight object detection model on an edge device. The task we constructed was to detect Canisters and whether they feature a protective valve called a Cap or not (called a No-Cap). READ MORE

  3. 3. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

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

    Author : Grigore-Leon Ratiu; [2024]
    Keywords : Physics and Astronomy;

    Abstract : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. READ MORE

  4. 4. AI-based image generation: The impact of fine-tuning on fake image detection

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Nick Hagström; Anders Rydberg; [2024]
    Keywords : Fake image detection; LoRA; DreamBooth; Stable Diffusion; Image generation;

    Abstract : Machine learning-based image generation models such as Stable Diffusion are now capable of generating synthetic images that are difficult to distinguish from real images, which gives rise to a number of legal and ethical concerns. As a potential measure of mitigation, it is possible to train neural networks to detect the digital artifacts present in the images synthesized by many generative models. READ MORE

  5. 5. Exploring the Depth-Performance Trade-Off : Applying Torch Pruning to YOLOv8 Models for Semantic Segmentation Tasks

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

    Author : Xinchen Wang; [2024]
    Keywords : Deep Learning; Semantic segmentation; Network optimization; Network pruning; Torch Pruning; YOLOv8; Network Depth; Djup lärning; Semantisk segmentering; Nätverksoptimering; Nätverksbeskärning; Fackelbeskärning; YOLOv8; Nätverksdjup;

    Abstract : In order to comprehend the environments from different aspects, a large variety of computer vision methods are developed to detect objects, classify objects or even segment them semantically. Semantic segmentation is growing in significance due to its broad applications in fields such as robotics, environmental understanding for virtual or augmented reality, and autonomous driving.
