  4. 3. Computer-based detection of cardiac arrhythmias : methods and systems

    Författare :Mats-Erik Nygårds; Linköpings universitet; []
    Nyckelord :Arrhythmia; monitoring; feature extraction; QRS delineation; power spectrum; ventricular fibrillation; MEDICINE; MEDICIN;

    Sammanfattning : The aim of this study was to develop methods and systems which could improve the accuracy or arrhythmia monitoring and analysis of long-term ECGs and eliminate or reduce the need for continuous visual ECG screening. The detection of arrhythmias was based on an automatic classification of heart beats, using waveform features obtained from a basis signals representation. LÄS MER

  5. 4. Tailoring the Optical Response of III-V Nanowire Arrays

    Författare :Mahtab Aghaeipour; Håkan Pettersson; Mats-Erik Pistol; Nicklas Anttu; Lars Samuelson; Constance J. Chang-Hasnain; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V nanowires; absorption; optical modes; photovoltaics; III-V nanowires; absorption; optical modes; photovoltaics; Fysicumarkivet A:2017:Aghaeipour;

    Sammanfattning : Semiconductor nanowires show a great deal of promise for applications in a wide range of important fields, including photovoltaics, biomedicine, and information technology. Developing these exciting applications is strongly dependent on understanding the fundamental properties of nanowires, such as their optical resonances and absorption spectra. LÄS MER

  7. 5. Iron in the Lena River basin, NE Russia : Insights from microscopy, spectroscopy and isotope analysis

    Författare :Catherine Hirst; Carl-Magnus Mörth; Per Andersson; Mats Erik Åström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; iron; reactivity; isotopes; permafrost; river; Arctic; Marine Geology; maringeologi;

    Sammanfattning : Iron is an important mediator of biotic and abiotic processes on the Earth’s surface, being an electron acceptor in organic matter degradation, a surface for organic matter and trace element adsorption, and a required element for enzymatic processes during primary production. Yet, the role of iron as a mediator of carbon and trace element cycling in high latitude, permafrost-dominated regions remains poorly investigated. LÄS MER
