  1. 1. Identification of photodegradation products from commonenvironmental pollutants using gas chromatography coupled withhigh resolution mass spectrometry

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Vanessa Cajes; [2022]
    Keywords : Photodegradation; Organic contaminants; High resolution mass spectrometry; Identification; Spectral library;

    Abstract : Photodegradation is a major degradation mechanism for many environmental contaminants, both in indoor environments as well as in outdoor environments, and many of the contaminants are persistent and toxic. However, there is a lack of knowledge about the exact degradation process for many of them. READ MORE

  2. 2. Estimating the risk of insurance fraud based on tonal analysis

    University essay from Lunds universitet/Matematisk statistik

    Author : Henrik Steneld; [2022]
    Keywords : Spectral analysis; Speaker recognition; Tonal analysis; Speaker Diarization; Machine Learning; LSTM; ResNet; Fraud detection; Mathematics and Statistics;

    Abstract : Insurance companies utilize various methods for identifying claims that are of potential fraudulent nature. With the ever progressing field of artificial intelligence and machine learning models, great interest can be found within the industry to evaluate the use of new methods that may arise as a result of new advanced models in combination with the rich data that is being gathered.

    Keywords : active galactic nucleus; black hole; AGN; Fermi-LAT; JetSeT;

    Abstract : An analysis is made on the Flat Spectrum Radio Quasar PKS 0426-380 using two sets of data. The first set of data is the Fermi-LAT data collected over the time 54682.66 − 59317.66 in Modified Julian Date within the energy range of 100 MeV to 500 GeV. READ MORE

  4. 4. Spectral density approach for dynamic analysis of high-speed railway bridges

    University essay from KTH/Bro- och stålbyggnad

    Author : Alket Ciku; Vlad Gavriliuc; [2022]
    Keywords : ;

    Abstract : The focus of this thesis is to introduce the concept of train signature in the spectraldensity approach used in the dynamic analysis of simply-supported railway bridges.Due to the increased transportation demands, longer trains with higher axles loadsand top speeds are being developed.

  5. 5. Identification of spectral features differentiating fungal strains in infrared absorption spectroscopic images

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik

    Author : Dejan Stancevic; [2022]
    Keywords : Physics and Astronomy;

    Abstract : There are many unknowns regarding the interaction between fungi and their surroundings. In this project, we took a closer look at hyperspectral images of several fungal strains on two different substrates. The project mainly consisted of developing a code for the classification of fungal strains and the extraction of information from it. READ MORE
