1. 16. Indocyanine-green fluorescence imaging to detect anastomotic insufficiency after esophagectomy

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Författare :Love Kildetoft; [2024]
   Nyckelord :Fluorescence; Imaging; Indocyanine-green; ICG; Esophageal cancer; Physics; Photonics; Image Analysis; Blood Perfusion; Anastomotic leakage; Anastomotic insufficiency; Physics and Astronomy;

   Sammanfattning : This research project is concerned with the development of simulation models and image analysis algorithms, as well as instrumentation for characterizing anastomotic leakages after a patient has undergone surgery for esophageal cancer. Anastomotic leakage is a high-incidence complication after esophagectomy, a surgical procedure for esophageal cancer. LÄS MER

3. 17. An Empirical Survey of Bandits in an Industrial Recommender System Setting

   Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :Tobias Schwarz; Johan Brandby; [2023-09-21]
   Nyckelord :computer science; industrial application; machine learning; reinforcement learning; multi-armed bandits; MAB; contextual multi-armed bandits; survey; batch learning;

   Sammanfattning : In this thesis, the effects of incorporating unstructured data—images in the wild—in contextual multi-armed bandits are investigated, when used within a recommender system setting, which focuses on picture-based content suggestion. The idea is to employ image features, extracted by a pre-trained convolutional neural network, and study the resulting bandit behaviors when including respective excluding this information in the typical context creation, which normally relies on structured data sources—such as metadata.

4. 18. A computational model of metapopulation dynamics and organism-mediated nutrient flow

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

   Författare :Amanda Hansson; [2023-08-07]
   Nyckelord :computational model; population dynamics; metapopulation dynamics; nutrient flow; simulation; spatially explicit; individual-based;

   Sammanfattning : The aim of this project was to assess, using in-silico experiments, how different life history char-acteristics, such as age at maturity and dispersal ability of individuals, influence the dynamics of a metapopulation. To achieve this, a novel model of a spatially explicit metapopulation, with organ-ism-mediated nutrient flow between fragmented habitat patches, was implemented by means of computer simulations.

5. 19. A study of productivity measurement and modeling of inhaler production at AstraZeneca

   Master-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

   Författare :Vilma Björk Öhhrfelt; Ebba Österman; [2023]
   Nyckelord :Produktivitet; produktivitetsmått; produktionsplanering; diskret händelsestyrd simulering; kapacitetsförändringar; produktionslogistik; Industriell ekonomi; Industriell ekonomi;

   Sammanfattning : Production planning and evaluation can be performed using various tools. This study encompasses two main topics: productivity measurement and production simulation. The study was conducted at AstraZeneca, a pharmaceutical company, where their production of inhalers was examined. LÄS MER

7. 20. Activity Location Assignment Comparison Using Geospatial Landuse and Building Data in MATSim : A Multi-modal Transport Case Study of Stockholm

   Master-uppsats, KTH/Transportplanering

   Författare :YU GAO; [2023]
   Nyckelord :Agent-based model; MATSim; Raster Data; Shapefile Data; OSM; GTFS;

   Sammanfattning : Transport simulation models play a crucial role in transportation planning, design, and operations, allowing for the replication of various scenarios through the incorporation of real-world data and parameters. Recently, agent-based transport models have gained prominence for their ability to simulate intricate metropolitan transport systems. LÄS MER
