1. 1. Geophysical Data from Norrbotten, Sweden - Evidence for the Presence of a Crustal Scale Fault?

   University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

   Author : Jimmy Markström; [2022]
   Keywords : Self-Organizing Maps; Magnetic Anomaly; Radioisotopes; Geological Faults;

   Abstract : The method of combining multiple geophysical, geological, or geochemical datasets can reveal patterns of otherwise hidden features in the Earth’s crust. This may aid in geological mapping, locating economic mineral deposits and for general anomaly/feature detection. READ MORE

4. 3. Presence detection by means of RF waveform classification

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

   Author : Max Lengdell; [2022]
   Keywords : presence detection; machine learning; radio wave classification; unsupervised learning; supervised learning; sensor fusion; unsupervised classification;

   Abstract : This master thesis investigates the possibility to automatically label and classify radio waves for presence detection, where the objective is to obtain information about the number of people in a room based on channel estimates. Labeling data for machine learning is time consuming and tedious process. To address this two approaches are evaluated. READ MORE

5. 4. Diagnosis of Synoptic Weather Patterns Causing Heavy Rainfall Occurrence Using Self-Organizing Maps

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Aoi Kasai; [2021]
   Keywords : Self-Organizing Map; heavy rainfall frequency; classification; meteorological fields; prediction; heavy rainfall risk; Technology and Engineering;

   Abstract : The annual number of events with precipitation over 50 mm/h have increased from 1970s and this trend is likely to be continued due to climate change in Kyushu, Japan. Therefore, it is important to recognize what kind of meteorological fields have contributed to the occurrence of heavy rainfall events and to reveal whether it is possible to diagnose heavy rainfall risk.
