  3. 2. Exploring Diversity of Spectral Data in Cloud Detection with Machine Learning Methods : Contribution of Near Infrared band in improving cloud detection in winter images

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Nakita Sunil Oza; [2022]
    Nyckelord :Remote sensing; Multispectral imaging; Cloud detection; Data diversity; Deep learning; Fjärranalys; Multispektral bildbehandling; Molndetektion; Datadiversitet; Djupinlärning;

    Sammanfattning : Cloud detection on satellite imagery is an essential pre-processing step for several remote sensing applications. In general, machine learning based methods for cloud detection perform well, especially the ones based on deep learning as they consider both spatial and spectral features of the input image.

  4. 3. Building an in-house spectral library using GCorbitrap HRMS

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Elias Kolsmyr; [2022]
    Nyckelord :Environmental contaminants; Plastic additives; Gas chromatography; High resolution mass spectrometry; Spectral library; MS-DIAL;

    Sammanfattning : There are a great variety of environmentals contaminants, a lot of which are understudied asit is today. The aim of this study was to develop an in-house high-resolution spectral librarycontaining environmental contaminants, with focus on plastic additives. The spectral librarywould then be used to perform suspect screening on real sample extracts. LÄS MER

  5. 4. Bedömning av anestesidjupet under generell anestesi med hjälp av spectral edge frequency

    Magister-uppsats,

    Författare :Amanda Bäckström; Klara Hedhman; [2021-05-18]
    Nyckelord :Spectral edge frequency; generell anestesi; tillförlitlighet; evidensbaserad vård;

    Sammanfattning : Bakgrund: Generell anestesi syftar till att häva känselintryck genom användning av olika anestetiska läkemedel. Bedömning av anestesidjupet är en stor del av anestesisjuksköterskans vardag. Anestesidjupsmonitorn SEF skulle kunna vara ett hjälpmedel för att undvika intraoperativa över- och underdoseringar.

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

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

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

    Sammanfattning : 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.
