  1. 1. Image Distance Learning for Probabilistic Dose–Volume Histogram and Spatial Dose Prediction in Radiation Therapy Treatment Planning

    University essay from KTH/Matematisk statistik

    Author : Ivar Eriksson; [2020]
    Keywords : Radiation therapy; automated planning; machine learning; autoencoder; distance optimisation; sparse pseudo-input Gaussian process; kernel density estimation; dose mimicking; dose–volume histogram; Strålbehandling; automatiserad dosplanering; maskininlärning; autoencoder; distansoptimering; glesa Gaussiska processer; sannolikhets-fördelnings-estimering; dosrekonstruktion; dos–volymhistogram;

    Abstract : Construction of radiotherapy treatments for cancer is a laborious and time consuming task. At the same time, when presented with a treatment plan, an oncologist can quickly judge whether or not it is suitable. This means that the problem of constructing these treatment plans is well suited for automation. READ MORE

  2. 2. Karaktäristika hos säsongsmigration : en studie av en svensk-norsk älgpopulation

    University essay from SLU/Dept. of Ecology

    Author : Erik Berg; [2020]
    Keywords : migration; förflyttning; net squared displacement; älg; spatial ekologi; förflyttningsstrategier; modeller; könsskillnader;

    Abstract : Att förstå var djur befinner sig och hur de förflyttar sig över året är en viktig del i arbetet för att nå en effektiv förvaltning. Extra viktigt är det när arten i fråga berör en stor mängd människor, både ekonomiskt och kulturellt. READ MORE

  3. 3. Is there a geographical difference in wolverine (Gulo gulo) home range size at different spatial and temporal scales in Scandinavia?

    University essay from SLU/Dept. of Ecology

    Author : Elin Olsson; [2020]
    Keywords : home range; seasonal; monthly; Gulo gulo; wolverine; Scandinavia; spatial; temporal;

    Abstract : A home range is the area that is covered by the animals normal day-to-day activity. The home range size may be influenced by factors such as abundance and distribution of food, sex, spatial organisation and population density. READ MORE

  4. 4. On the statistics and practical application of the reassignment method for Gabor spectrograms

    University essay from Lunds universitet/Matematisk statistik

    Author : Erik. M Månsson; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : The reassignment method is a technique for improving the concentration of signals in spectrograms and other time-frequency representations (TFR). It achieves this by displacing the points in a TFR according to the reassignment vector for every point. READ MORE

  5. 5. The Missing People of Malthi : A kernel density analysis based on Middle Helladic Ceramics

    University essay from Uppsala universitet/Institutionen för arkeologi och antik historia

    Author : Anna Sunneborn Gudnadottir; [2019]
    Keywords : GIS; KDE; Bronze Age Greece; Middle Helladic; Malthi; household archaeology; Formation processes; Messenia;

    Abstract : This study aims to identify human interference and tendencies in the Bronze Age settlement of Malthi, Greece. It has employed a spatial analysis, a Kernel Density Estimate, to locate areas of anthropic interference and evaluate if the initial excavation report, despite its flaws, can be used in newer research.
