  1. 21. Noise Reduction of Scintillation Camera Images Using UNET: A Monte Carlo Simulation Approach

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Johanna Korpijärvi; [2021]
    Keywords : Medicine and Health Sciences;

    Abstract : Background The project aims to reduce the noise in planar 111-In projections with a machine learning model. Method Sixteen base phantoms were used to create 696 phantoms in XCAT. An anterior planar projection was simulated with 111-In and ten uptake curves for each phantom in SIMIND. READ MORE

  3. 22. Greenhouse gas emissions from compacted peat soil

    University essay from SLU/Dept. of Soil and Environment

    Author : Antonia Hartmann; [2021]
    Keywords : carbon dioxide; compression index; Peatland agriculture; recompression index; sand addition; soil compaction;

    Abstract : Cultivated peat soils are a main driver for CO2 and N2O emissions, while the gas fluxes are dependent on intrinsic soil properties and land use. Sand addition into peat soils might reduce greenhouse gas (GHG) emissions and enhance soil strength, and thus the ability to tolerate soil compaction. READ MORE

  4. 23. Evaluation of non-pharmaceutical intervention effectiveness in Covid-19 pandemic by using excess mortality metric

    University essay from Södertörns högskola/Miljövetenskap

    Author : Miglė Urbonaite; [2021]
    Keywords : non-pharmaceutical interventions; disease management; Covid-19;

    Abstract : INTRODUCTION: The study focuses on finding a methodology for evaluating the effectiveness of the nonpharmaceutical intervention in the face of a new pathogen entering the population. Different interventions can have different effectiveness levels in different populations; thus, studying possible correlations and effectiveness among different groups is essential. READ MORE

  5. 24. Tidying up the factor zoo: Using machine learning to find sparse factor models that predict asset returns.

    University essay from Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Author : Oliver Klingberg Malmer; Gustav Pettersson; [2020-07-01]
    Keywords : Asset pricing; Factor models; Machine learning; PCA; LASSO; Variable selection; Dimension reduction; Fama French Three Factor model; Fama French Five Factor model;

    Abstract : There exist over 300 firm characteristics that provide significant information about average asset return. John Cochrane refers to this as a “factor zoo” and challenges researchers to find the independent characteristics which can explain average return. READ MORE

  6. 25. Water Insoluble Fraction of Nopal (Opuntia ficus) Cladodes Beneficially Affects Postprandial Appetite-related Variables, while the Soluble Fraction Has No Effect: A Randomized Crossover Study in Healthy Volunteers

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Phuong Dung Kieu; [2020]
    Keywords : Nopal cladodes; appetite variables; dietary fiber; hydrolysis index; obesity; applied nutrition; food chemistry; industriell näringslära; livsmedelskemi; Medicine and Health Sciences;

    Abstract : Introduction: The world has witnessed a global trend of increasing obesity, which is directly linked to non-communicable diseases, such as type 2 diabetes (T2D). The epidemic of obesity is largely associated with consumption of high calorie diets and low physical activity. READ MORE
