  1. 1. Applications of Pulse Shape Analysis Techniques for Segmented Planar Germanium Detectors

    Författare :Anton Khaplanov; Bo Cederwall; Bo Jakobsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Position sensitive detectors; pulse shape analysis; germanium detectors; DESPEC; ; Nuclear physics; Kärnfysik;

    Sammanfattning : The application of pulse shape analysis (PSA) and γ-ray tracking techniques has attracted a great deal of interest in the recent years in fields ranging from nuclear structure studies to medical imaging. These new data analysis methods add position sensitivity as well as directional information for the detected γ-rays to the excellent energy resolution of germanium detectors. LÄS MER

    Sammanfattning : Orthogonal Frequency Division Multiplexing (OFDM) is well known as an efficient technology for wireless communications and is widely used in many of the current and upcoming wireless and wireline communication standards. However, it has some intrinsic drawbacks, e.g. LÄS MER

  5. 4. Analysis and Monitoring of Laser Welding and Surface Texturing

    Författare :Rickard Olsson; Alexander Kaplan; John Powell; Jan Frostevarg; Michael Zäh; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser welding; monitoring; Signal processing; laser texturing; texture analysis; Produktionsutveckling; Manufacturing Systems Engineering;

    Sammanfattning : This thesis can be conveniently divided into three sections as follows;Part I. Monitoring of laser welding In laser materials processing there has always been a need for suitable methods to supervise and monitor the processes on-line, to ensure correct production quality or to trigger alarms when failures are detected.

  7. 5. Digital block transmission and time-of-flight estimation : receiver design and performance analysis

    Författare :Håkan B. Eriksson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : This thesis is concerned with signal processing aspects of digital block transmission and time-of-flight estimation. Receivers are derived and analysed based on the assumption that the received signals have been corrupted with additive Gaussian noise and linear distortion. LÄS MER
