  1. 1. Ledarskap på ett medicintekniskt bolag: en studie om engagemang och upplevd effektivitet

    Kandidat-uppsats, Lunds universitet/Institutionen för psykologi

    Författare :Elsa Paulsson; Adina Centervall; [2023]
    Nyckelord :developmental leadership; engagement; perceived effectiveness; engineers; STEM organizations; utvecklande ledarskap; engagemang; upplevd effektivitet; ingenjörer; STEM-organisationer; Technology and Engineering; Social Sciences;

    Sammanfattning : Syftet med studien var att undersöka det utvecklande ledarskapets positiva utfall i form av engagemang och upplevd effektivitet på ett medicintekniskt bolag. Vidare ämnade studien att utforska eventuella samband mellan det utvecklande ledarskapets dimensioner (föredömligt autentiskt handlande, personlig omtanke samt inspiration och motivation) och engagemang samt upplevd effektivitet.

  3. 2. Generation of Synthetic White Blood Cell Images Using Denoising Diffusion

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Louise Zettergren; Fanny Nilsson; [2023]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : CellaVision’s digital hematology systems are designed to analyze blood and pre-classify different types of blood cells. Some abnormal white blood cells are rare, which can cause imbalanced datasets. This can lead to a decrease in pre- classification performance and a need to carry out more time-consuming data gathering. LÄS MER

  4. 3. Detecting red blood cells and platelets in blood smears using a single multi-class object detector

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Timothy Burfield; Sophia Carlsson; [2022]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Blood analysis is an integral part of diagnostic medicine and used in most medical fields. The concentrations of red blood cells and platelets, and ratio between these, are used for diagnosing several diseases. CellaVision develops machines and software for automatically capturing images of blood sample smears and detecting its cellular contents. LÄS MER

  5. 4. Pre-classification of Hairy Cells Using Supervised Contrastive Learning

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Alexia Han; Rebecca Schömer Ericsson; [2022]
    Nyckelord :supervised contrastive learning; hairy cells; abnormal lymphocytes; deep learning; Cellavision; Xception; artificial neural network; convolutional neural networks; Mathematics and Statistics;

    Sammanfattning : Differential of the peripheral blood is an important tool when assessing blood-related diseases. Lymphocytes are part of the immune system and morphological changes thereof should raise attention. LÄS MER

  7. 5. Domain adaptation for white blood cell classification - Bridging the gap created by optical hardware upgrades

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Elsa Lindhé; Erik Olsson; [2022]
    Nyckelord :Domain adaptation; leukocytes; WBC; machine learning; deep learning; Mathematics and Statistics;

    Sammanfattning : Collecting enough labeled images to train an artificial neural network (ANN) is a common struggle since the process is tedious, time consuming and expensive. CellaVision, a company that creates analyzers that automate the process of finding and pre-classifying abnormal blood cells using machine learning, runs into this problem regularly. LÄS MER
