  1. 41. Estimating the risk of insurance fraud based on tonal analysis

    Master-uppsats, Lunds universitet/Matematisk statistik

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

    Sammanfattning : 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.

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Alket Ciku; Vlad Gavriliuc; [2022]
    Nyckelord :;

    Sammanfattning : 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. 44. Identification of spectral features differentiating fungal strains in infrared absorption spectroscopic images

    Kandidat-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Dejan Stancevic; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : 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. LÄS MER

  7. 45. Building Orientation and Non-Image Forming Effects of Light. Connecting Simulation and reality in the case of Iggesund School.

    Magister-uppsats, KTH/Ljusdesign

    Författare :Gregor Ruta; [2022]
    Nyckelord :Alfa-Opic Metrics; Spectral Diet; OWL – Occupant Well-being through Lighting; Chronobiology; Daylight; Circadian Rhythmes; Melatonin; Vision;

    Sammanfattning : In recent years there has been an increase in the number of apartments in Sweden. The officials are estimating that approximately 1000 primary schools need to be built to meet the 20% increase in students. Facing the rising demand; my thesis makes a contribution to sustainable school design via optimisation of the building orientation. LÄS MER
