    Sammanfattning : The European Union (EU) is the most far-reaching attempt yet undertaken to institutionalize democratic policy-making beyond the nation-state. To what extent, and in what ways, do various channels of representation contribute towards the realization of this aim? This dissertation takes stock of current research on the EU’s system of representation, and seeks to expand its agenda so that this central question can be properly addressed. LÄS MER

  3. 2. Halftoning for Multi-Channel Printing : Algorithm Development, Implementation and Verification

    Författare :Paula Žitinski Elías; Sasan Gooran; Daniel Nyström; Mattias Andersson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A seemingly straightforward way to enhance the quality of printed images is to increase the number of colorants, beyond the four traditionally used, in multi-channel printing. Potential improvements to reproduced images include: increased colour accuracy, enhanced colour smoothness and reduced image graininess. LÄS MER

  4. 3. Mobility and Multi-channel Communications in Low-power Wireless Networks

    Författare :António Gonga; Mikael Johansson; Riku Jäntti; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobility; Multi-channel communications; Neighbor Discovery; MAC Protocols; Low-power Wireless Networks; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The prospect of replacing existing fixed networks with cheap, flexible and evenmobile low-power wireless network has been a strong research driver in recent years.However, many challenges still exist: reliability is hampered by unstable and burstycommunication links; the wireless medium is getting congested by an increasingnumber of wireless devices; and life-times are limited due to difficulties in developingefficient duty-cycling mechanisms.

  5. 4. Multiscale analysis of multi-channel signals

    Författare :Håkan Carlqvist; Jan-Olov Strömberg; Maria Hansson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; Matematisk statistik; Mathematical statistics; Matematisk statistik;

    Sammanfattning : I: Amplitude and phase relationship between alpha and beta oscillations in the human EEG We have studied the relation between two oscillatory patterns within EEG signals (oscillations with main frequency 10 Hz and 20 Hz), with wavelet-based methods. For better comparison, a variant of the continuous wavelet transform, was derived. LÄS MER

  7. 5. Characterization and Linearization of Multi-channel RF Power Amplifiers

    Författare :Shoaib Amin Amin; Peter Händel; Daniel Rönnow; Ulf Gustavsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The demands for high data rates and broadband wireless access require the development of wireless systems that can support wide and multi-band signals. To deploy these signals, new radio frequency (RF) front-ends are required which impose new challenges in terms of power consumption efficiency and sources of distortion e.g., nonlinearity. LÄS MER
