  1. 1. Hidden Markov Models for Intrusion Detection Under Background Activity

    University essay from KTH/Matematisk statistik

    Author : Robert Siridol-Kjellberg; [2023]
    Keywords : Hidden Markov models; Cyber security; Intrusion detection; Clustering; Background subtraction; Dolda Markovmodeller; Cybersäkerhet; Dataintrång; Klustring; Bakgrundssubtraktion;

    Abstract : Detecting a malicious hacker intruding on a network system can be difficult. This challenge is made even more complex by the network activity generated by normal users and by the fact that it is impossible to know the hacker’s exact actions. READ MORE

  3. 2. Quantification of DNA Microballs Using Image Processing Techniques

    University essay from KTH/Industriell bioteknologi

    Author : Yosef Werede Tedros; [2023]
    Keywords : Spot detection; Deep learning; Image processing; smFISH; Gene editing; CRISPR; Rolling circle amplification; Big-FISH; LodeSTAR; DeepSpot; Detektering av punkter; Djupinlärning; Bildbehandling; smFISH; Genredigering; CRISPR; Rolling circle amplification; Big-FISH; LodeSTAR; DeepSpot;

    Abstract : I detta examensarbete användes olika bildbehandlingstekniker för detektion och kvantifiering av DNA-mikrobollar, mer specifikt rolling circle amplification-produkter, på mikroskopibilder. Avsikten med detta arbete var att hjälpa Countagen AB utforska pipelines för bildbehandling för sin produkt där de analyserar utfallet av genredigeringsförsök på ett billigare och snabbare sätt än dagens konventionella sekvenseringsmetoder.

    Abstract : The use of external dimensions in products has great importance in numerous areas and a digital measurement can lead to a more streamlined workflow. In this project are the suitability of sensors for measuring irregularly shaped objects investigated and a prototype for digital measurement built. READ MORE

  5. 4. Prototyping of an automated cyclic Neutron Activation Analysis setup

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Cornelius Maurer; [2022]
    Keywords : Nuclear Physics; Neutron activation analysis; cyclic-NAA; Physics and Astronomy;

    Abstract : A prototype Neutron Activation Analysis (NAA) setup based on a Deuterium-Tritium (DT) neutron generator is under development at Lund University. It serves as proof-of-principle for NAA based on a Compact Accelerator-driven Neutron Source. READ MORE

  6. 5. Improving a Background Model for Tracking and Classification of Objects in LiDAR 3D Point Clouds

    University essay from Lunds universitet/Matematik LTH

    Author : Seamus Doyle; Gustav Nilsson; [2022]
    Keywords : LiDAR; Semantic Segmentation; Neural Networks; RandLA-NET; 3D Point Cloud; Gaussian Process Regression; Robust Locally Weighted Regression; CARLA; Ground Model; Technology and Engineering;

    Abstract : This thesis studied methods of improving a background model for a data processing pipeline of LiDAR point clouds. For this, two main approaches were evaluated. The first was to implement and compare three different models for detecting ground in a point cloud. These were based on more classical modeling approaches. READ MORE
