  3. 27. Spectrally Precoded OFDM-Design and Analysis

    Författare :Medhat Mohamad; Jaap van de Beek; Rickard Nilsson; Mérouane Debbah; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; OFDM; spectral precoding; out of band emission; 5G; Signalbehandling; Signal Processing;

    Sammanfattning : Despite shifting towards mm-wave bands, the sub-6 GHz band will continue to be a fundamental spectral band in 5G. However, the severe congestion in this band makes a well-constrained spectrum a critical requirementof 5G. LÄS MER

  4. 28. Viscoelastic Materials : Identification and Experiment Design

    Författare :Agnes Rensfelt; Torsten Söderström; Händel Peter; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; viscoelastic materials; complex modulus; system identification; optimal experiment design; distributed parameter systems; frequency domain identification; wave propagation; Automatic control; Reglerteknik; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : Viscoelastic materials can today be found in a wide range of practical applications. In order to make efficient use of these materials in construction, it is of importance to know how they behave when subjected to dynamic load. LÄS MER

  5. 29. Design for Recordkeeping: Areas of Improvement

    Författare :Erik A.M. Borglund; Viveca Asproth; Anita Håkansson; Anita Mirijamdotter; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Design; Electronic records; Information systems; Proactivity; Recordkeeping; Informatics; computer and systems science; Informatik; data- och systemvetenskap;

    Sammanfattning : This thesis is about problems related to design of information systems in which records are born and managed. The proactive approach has been derived from new archival theories suited for electronic recordkeeping, and implies that electronic records must, at the time of creation fulfil their current and future requirements.
