  1. 1. Characterisation of Non-metallic Inclusions in Special Steels using Electrolytic Extraction

    Master-uppsats, KTH/Materialvetenskap

    Författare :Josefin Mvele Svensson; [2024]
    Nyckelord :Non-metallic inclusions; electrolytic extraction; SEM; Icke-metalliska inneslutningar; elektrolytisk extraktion; SEM;

    Sammanfattning : When producing high strength special steels strict requirements are in place to assure the quality of the final product, both in terms of harmful elements and  the  content  of  non-metallic  inclusions  (NMI).  Achieving  cleanliness  is a  gradual  process  where all  the  steps  of  the  production  process  are  inter- connected, meaning that it is crucial to know the influence of each step in order to assure the contents of the final product.

  3. 2. Virtual H&E Staining Using PLS Microscopy and Neural Networks

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Sally Vizins; Hanna Råhnängen; [2024]
    Nyckelord :Deep learning; Virtual staining; Skin tissue; Hematoxylin Eosin; H E; Pathology; Carcinoma; Point light source illumination; Neural Networks; GANs; Generative adversarial networks; CNNs; Convolutional neural networks; Relativistic generative adversarial network; Unet; Digital microscopy; Attention-Unet; Dense-Unet; Mathematics and Statistics;

    Sammanfattning : Histopathological examination, crucial in diagnosing diseases such as cancer, traditionally relies on time- and resource-consuming, poorly standardized chemical staining for tissue visualization. This thesis presents a novel digital alternative using generative neural networks and a point light source (PLS) microscope to transform unstained skin tissue images into their stained counterparts.

  4. 3. IDENTIFICATION OF ENVIRONMENTALLY RELEVANT BENTHIC FORAMINIFERA FROM THE SKAGERRAK FJORDS BY DEEP LEARNING IMAGE MODELING

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Marko Plavetic; [2023-06-26]
    Nyckelord :benthic foraminifera; deep learning; environmental monitoring; YOLOv7;

    Sammanfattning : Over the several past decades, there has been increasing interest in using foraminifera as environmental indicators for coastal marine environments. As compared to macrofauna, which are currently used in environmental studies, foraminifera offer several distinct advantages as bioindicators, including short generation times, a high number of individuals per small sample volume, hard and durable tests with high preservation potential, and low cost of sample extraction.

  5. 4. Anti-Müllerskt hormon hos hanhund. Samband mellan avvikande testikelmorfologi, hormonets distribution i testikelvävnaden och koncentration i serum

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :August Rooth; [2023]
    Nyckelord :Anti-Müllerskt hormon; AMH; Sertolicell; kryptorkism; immunohistokemi; testikelmorfologi; hanlig fertilitet hos hund;

    Sammanfattning : Anti-Müllerskt hormon (AMH) är en av de första markörerna för hanlig könsutveckling i fosterstadiet hos däggdjur och fortsätter sedan att spela en stor roll för den hanliga fertiliteten. Hormonet produceras av testikelvävnadens Sertoliceller och bygger upp tubulära nätverk kallade seminiferösa tubuli, vari spermatogenesen äger rum. LÄS MER

  7. 5. Morphological study of PS/PMMA-matrix on glass, related to vapour pressure, mass-fraction, and size

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Gustav Larsson; [2023]
    Nyckelord :organic solar cells; polymer; morphology; film; AFM;

    Sammanfattning : The objective of this study is to observe how changing amount or ratio between dried mixes of poly-methyl-methacrylate and poly-styrene change the surface appearance, and how the results might inform future design of Organic photovoltaic cells, whom are based on polymer mixtures and heavenly dependent on the arrangement of polymers. An atomic force microscope was used on glass surfaces coated in a poly-methyl-methacrylate/poly-styrene matrix and dried from either dichloromethane or ethyl-acetate to determine surface appearance.
