  1. 1. The Role of Functional Traits and Trade-offs in Seasonal Succession of Phytoplankton Community Structuring : A numerical investigation of resource acquisition traits of Lake Constance

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Ayesha Nagahage; [2024]
    Keywords : Phytoplankton; resource acquisition; traits; trade-off; resource limitation;

    Abstract : Long-term ecological research in deep lakes offers valuable insights into understanding changes in trophic states and organization of phytoplankton assemblages. Utilizing five decades of phytoplankton taxonomic trait data from pre-alpine Lake Constance, a confirmed negative relationship was found between phosphate and light affinity at the annual community trait level.

  3. 2. Teleworking and the Countryside. An explorative thesis regarding telework as an enabler for residential relocations and life in the countryside

    University essay from Göteborgs universitet / Institutionen för ekonomi och samhälle

    Author : Joel Böhm; [2023-08-04]
    Keywords : teleworking; residential relocations; residential mobility; living countryside; work-life balance; co-working spaces;

    Abstract : The research on teleworking, and its spatial implications, is well explored. However, anticipations of a rising diffusion of teleworking never really got actualised, until a global pandemic emerged, and redrew the map of teleworking considerably. READ MORE

  4. 3. Optimising Machine Learning Models for Imbalanced Swedish Text Financial Datasets: A Study on Receipt Classification : Exploring Balancing Methods, Naive Bayes Algorithms, and Performance Tradeoffs

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Li Ang Hu; Long Ma; [2023]
    Keywords : Imbalanced datasets; Swedish text financial datasets; Accuracy; Matthews correlation coefficient; Recall; Multinomial Naive Bayes; SMOTE; TomekLinks; Performance optimization;

    Abstract : This thesis investigates imbalanced Swedish text financial datasets, specifically receipt classification using machine learning models. The study explores the effectiveness of under-sampling and over-sampling methods for Naive Bayes algorithms, collaborating with Fortnox for a controlled experiment. READ MORE

  5. 4. Kernel Methods for Regression

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Tom Lennart Rossmann; [2023]
    Keywords : Kernel Methods; Regression; Ridge Regression;

    Abstract : Kernel methods are a well-studied approach for addressing regression problems by implicitly mapping input variables into possibly infinite-dimensional feature spaces, particularly in cases where standard linear regression fails to capture non-linear relationships in data. Therefore, the choice between standard linear regression and kernel regression can be seen as a tradeoff between constraints on the number of features and the number of training samples. READ MORE

  6. 5. Implementation and Comparative Analysis of Head-Related and Binaural Room Impulse Response in a Mid-Side Decomposition

    University essay from KTH/Teknisk akustik

    Author : Jonathan Ling; [2023]
    Keywords : Master’s Thesis; Spatial audio; Sound Externalisation; Binaural recording; Headphones; Mid-Side Processing; Masteruppsats; Rumsligt Ljud; Ljud-externalisation; Binaural Inspelning; Hörlurar; Mid-Sid processering;

    Abstract : This thesis aimed to clarify the essential factors involved in externalising audio over headphones. Extensive research was conducted, examining binaural cues and the latest advancements in the field. A novel approach was proposed, which applied HRIRs and BRIRs on a Mid-Side decomposition. READ MORE
