  1. 1. 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 : Background: The purpose of general anesthesia are to remove emotional impressions with different anesthetic drugs. A big part of the nurse of anesthesia everyday life is to assess the depth of anesthesia. SEF could help to prevent over- and underdosage intraoperative. LÄS MER

  2. 2. Detecting bark beetle damage with Sentinel-2 multi-temporal data in Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Shuo Yang; [2019]
    Nyckelord :Physical Geography and Ecosystem Analysis; Remote Sensing; Bark Beetle; Insect Detection; Sentinel-2; Forest Health; Maximum Likelihood; Random Forest; Spectral Signature; Vegetation Indices; Earth and Environmental Sciences;

    Sammanfattning : The European spruce bark beetle is considered as one of the most destructive forest insects to Norway spruce trees in Europe. Climate change may increase the frequency and intensity of bark beetle outbreaks. It is therefore of vital importance to detect the bark beetle outbreaks and take it under control to prevent further damages. LÄS MER

  3. 3. Pattern Reconfigurable MIMO Antennas for Multiband LTE Operation

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Rui Ma; Ioannis Chountalas; [2015]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Nowadays, multiple antennas are becoming widely used in small mobile terminals as they can significantly improve wireless communication performance in terms of link reliability and spectral efficiency. Also, pattern reconfiguration is another new trend for antenna design as it enables the antennas to adapt to different propagation and user scenarios. LÄS MER

  4. 4. Study of the Optical Properties of sp2-Hybridized Boron Nitride

    Master-uppsats, Linköpings universitet/Tillämpad optik

    Författare :Eduardo Antunez de Mayolo; [2014]
    Nyckelord :Spectroscopic ellipsometry; boron nitride; optical properties; materials characterization; III-V nitride semiconductors; cathodoluminescence; electron microscopy; Raman spectroscopy;

    Sammanfattning : Nitride-based semiconductor materials make it possible to fabricate optoelectronic devices that operate in the whole electromagnetic range, since the band gaps of these compounds can be modified by doping. Among these materials, the sp2-hybridized boron nitride has properties that make it a potential candidate for integration in devices operating in the short-wavelength limit, under harsh environment conditions, due to the strength of the B-N bond.

  5. 5. Discrete Cosine Transform for Pre-coded EGPRS

    Master-uppsats, KTH/Signalbehandling

    Författare :Chengzhou Jin; [2012]
    Nyckelord :;

    Sammanfattning : Due to the rapid growth of wireless multimedia service, new features such as improved spectral efficiency, latency and increased peak throughput are standardized in the current GSM/EDGE system. Higher order modulations and symbol rates are defined in Enhanced General Packet Radio Service phase 2 (EGPRS2) to achieve better throughput. LÄS MER
