1. 11. Analogue Circuit for Detection of Ageing Phenomena in Electric Drives

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Yudong Lin; [2023]
   Keywords : Electric Drives; Ageing Process; Pulse-Width Modulation; Ringing Current; Peak Holder; Analogue Circuits; Elektriska drivsystem; Åldringsprocess; Pulsbreddsmodulering; Ringningar i strömmen; Toppvärdesdetektor; Analog krets;

   Abstract : This master thesis presents an analogue peak holder circuit design aimed at facilitating the non-invasive inspection of the ageing process in electric drives. The ageing process of electric drives is a crucial aspect that demands accurate monitoring to ensure their long-term performance and reliability. READ MORE

3. 12. 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

4. 13. Anomaly Detection in the EtherCAT Network of a Power Station : Improving a Graph Convolutional Neural Network Framework

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Niklas Barth; [2023]
   Keywords : Unsupervised Learning; Multivariate Time Series; Graph Convolutional Neural Networks; Anomaly Detection; Industrial Control System; EtherCAT; Power Station; Electricity Grid;

   Abstract : In this thesis, an anomaly detection framework is assessed and fine-tuned to detect and explain anomalies in a power station, where EtherCAT, an Industrial Control System, is employed for monitoring. The chosen framework is based on a previously published Graph Neural Network (GNN) model, utilizing attention mechanisms to capture complex relationships between diverse measurements within the EtherCAT system.

5. 14. PAMPaR: Parallel Analysis of miRNAs, Proteins and RNAs. Dynamic Profiles of miRNAs, mRNAs and Specific Proteins in Mouse Embryonic Stem Cells Differentiating into Neural Precursors

   University essay from KTH/Proteinvetenskap

   Author : Amelie Carlström; [2023]
   Keywords : PAMPaR; SPARC; Proximity extension assay; Neuronal differentiation; Mouse embryonic stem cells; PAMPaR; SPARC; Proximity extension assay; Neuronal differentiering; embryonala musstamceller;

   Abstract : MikroRNA-molekyler (miRNA) är viktiga icke-kodande RNA-molekyler för post-transkriptionell reglering av proteinkodande gener. De har även effekter på många cellulära processer såsom differentiering. De biosyntetiska reaktioner som skapar miRNA involverar proteiner som själva regleras av miRNA. READ MORE

6. 15. Masking revealing hardware attributes in the source code of a hypervisor : A study exploring strategies to hide the identity of virtual environments during malware analysis

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Kevin Engström; Robin Lenz; [2023]
   Keywords : Sandbox detection; analysis evasion; virtual environment; masking;

   Abstract : Background: Malware is responsible for a significant part of the ever increasing cost of cyberattacks. Malware analysis is an important part in minimizing these costs. READ MORE
