  1. 1. Unauthorised Session Detection with RNN-LSTM Models and Topological Data Analysis

    University essay from KTH/Matematik (Avd.)

    Author : Nazar Maksymchuk Netterström; [2023]
    Keywords : Recurrent Neural Network; Long-Short-Term-Memory; Topological Data Analysis; Session based data; Anomaly detection; Time-series analysis; Imbalanced data; Master thesis; Neurala nätverk; Topologisk data analys; Detektion av avvikelse; Sessionsbaserad data; Tidserieanalys; Inbalancerad data; Masteruppsats;

    Abstract : This thesis explores the possibility of using session-based customers data from Svenska Handelsbanken AB to detect fraudulent sessions. Tools within Topological Data Analysis are employed to analyse customers behavior and examine topological properties such as homology and stable rank at the individual level. READ MORE

  3. 2. Robustness of State-of-the-Art Visual Odometry and SLAM Systems

    University essay from KTH/Tillämpad fysik

    Author : Cassandra Mannila; [2023]
    Keywords : Visual-Inertial Odometry; Visual Odometry; SLAM; Motion blur; ORB-SLAM3; DM-VIO; Robustness;

    Abstract : Visual(-Inertial) Odometry (VIO) and Simultaneous Localization and Mapping (SLAM) are hot topics in Computer Vision today. These technologies have various applications, including robotics, autonomous driving, and virtual reality. They may also be valuable in studying human behavior and navigation through head-mounted visual systems. READ MORE

  4. 3. Interleaved Practice : The role of habits in the implementation of a new technique

    University essay from Uppsala universitet/Institutionen för pedagogik, didaktik och utbildningsstudier

    Author : Andrew Grant; [2023]
    Keywords : Interleaved practice; professional development; habits; stress; Interleaved practice; lärarutveckling; vanor; stress;

    Abstract : Teaching is a complex and stressful job and despite efforts to consolidate the understanding of professional development programs, the effectiveness of such programs in real schools remains inconsistent. In this study, habit is used to understand the barriers to teacher development when looking to implement “interleaved practice” in mathematics. READ MORE

  5. 4. Hur mår undervisningshundarna emotionellt vid Sveriges lantbruksuniversitet när de används i undervisning?

    University essay from SLU/Dept. of Clinical Sciences

    Author : Julia Enbom; Lorena Gallardo Zapata; [2023]
    Keywords : 3R; ; alternativa metoder; beteende; djurvälfärd; försöksdjur; lågstresshantering; stress; veterinärmedicin;

    Abstract : Levande hundar används inom veterinärmedicinska utbildningar för att ge studenter praktisk kunskap och praktiska färdigheter innan de går ut i arbetslivet. Några argument för att använda levande djur i undervisningssyfte är att själva hanteringen av djur och att tolka djurs signaler inte går att lära sig via simulatorer eller liknande verktyg.

  6. 5. Steel-to-concrete connections in narrow concrete corners

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Daniel Carlson Bjernald; Emil Lönn; [2022]
    Keywords : Concrete; steel bolts; concrete failure modes; Abaqus; numerical calculations; concrete cone failure; concrete damaged plasticity; Technology and Engineering;

    Abstract : A commonly occurring problem when designing steel-to-concrete connections in corners with space deficits is the necessity for irregularly placed bolts with regards to design codes. The complexity of the calculations for the irregular placements of bolts generates the need to use simplified models during the design. READ MORE
