  1. 1. Reconstruction of Fire Spread with a Markov Random Field Mixture Model

    University essay from Lunds universitet/Matematisk statistik

    Author : Marcus Gehrmann; [2023]
    Keywords : Forest fire; fire scars; spatial statistics; Markov random field; EM-algorithm; pseudo-likelihood; Mathematics and Statistics;

    Abstract : This thesis revolves around reconstructing fire sizes for historical fires in Jämtgaveln, Sweden based on data of fire scars in trees. We propose a Hidden Markov Model (HMM), where the domain is divided into quadratic grid cells of 250 $\times$ 250 m and with these grid cells we associate a binary Markov random field taking values 0 or 1 corresponding to no fire and fire respectively.

  3. 2. Investigation of Machine Learning Methods for Anomaly Detection and Characterisation of Cable Shoe Pressing Processes

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Elliot Härenby Deak; [2021]
    Keywords : Machine Learning; LSTM; kNN; Time-series Classification; Anomaly Detection;

    Abstract : The ability to reliably connect electrical cables is important in many applications. A poor connection can become a fire hazard, so it is important that cables are always appropriately connected. This thesis investigates methods for monitoring of a machine that presses cable connectors onto cables. READ MORE

  4. 3. Sound ranging using multilateration and Kalman filter

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Tobias Samuelsson; [2020]
    Keywords : Technology and Engineering;

    Abstract : Sound ranging is a method to locate sources of sound waves using microphones or other types of receivers at known reference positions. Nowadays, these receivers can be made both very small and powerful, lasting for a long time on a single battery charge, making them suitable for longtime outdoor purposes such as detecting artillery fire or other loud sounds.

  5. 4. A vision based on surveillance system using a wireless sensor network

    University essay from KTH/Reglerteknik

    Author : Niklas Lundell; [2010]
    Keywords : ;

    Abstract : The aim of this thesis project is to implement a vision based surveillance system in a wireless sensor network running the Contiki operating system. After a comparative review of experimental cameras the decision fell on the Cmucam3. Hardware and software to integrate the camera with a Tmote Sky mote were created. READ MORE
