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

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Nazar Maksymchuk Netterström; [2023]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Bioinformatic approaches for detecting homologous genes in the genomes of non-model organisms : A case study of wing development genes in insect genomes

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Evolutionsbiologi

    Författare :Lauri Mesilaakso; [2019]
    Nyckelord :bioinformatics; homology detection; exonerate; BLAST; non-model organisms; homologous genes; wing development genes;

    Sammanfattning : Identifying homologous genes, that is genes from a common ancestor, is important in comparative genomic studies for understanding gene annotation and the predicted function of a gene. Several pieces of software, of which the most well-known is BLAST, have been developed for identifying homologues, but this can be challenging in non-model organisms where sometimes poor quality of genome assemblies and lack of annotation make it difficult to robustly identify homologues.

  4. 3. Initial evaluation of the Meritas Troponin I test for measurement of equine cardiac troponin I

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Malin Eriksson; [2014]
    Nyckelord :troponin; cTnl; horse; equine; cardiac disease; cardiovascular disease; cardiac biomarker; colic;

    Sammanfattning : Cardiac troponin I (cTnI) is considered a specific and a sensitive biomarker of cardiac disease, and due to a high inter-species sequence homology; human cTnI assays can often be used in veterinary medicine. The main aim of this study was to perform an initial evaluation of a human cTnI test, the Meritas Troponin I test, for measurement of equine plasma cTnI, in order to investigate whether the test could be a possible subject for a more comprehensive validation.

  5. 4. Molecular studies on infections with two nidoviruses: Bovine Coronavirus and Equine Arteritis Virus

    L3-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Lihong Liu; [2004]
    Nyckelord :equine arteritis virus; genetic variation; open reading frame; RT-PCR;

    Sammanfattning : Infections with nidoviruses can cause various problems in animals and human beings. Bovine coronavirus (BCoV) has been considered as an important pathogen, causing severe diarrhea of newborn calves, winter dysentery of adult cattle, and respiratory disease in calves. LÄS MER
