1. Political Representation in the European Union : A Multi-Channel Approach
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
2. Halftoning for Multi-Channel Printing : Algorithm Development, Implementation and Verification
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
3. Mobility and Multi-channel Communications in Low-power Wireless Networks
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.

4. High level modeling and evaluation of multi-channel services
Sammanfattning : The objective of this thesis is two-fold: (1) to study potential factors which influence users’ adoption of mobile services, and (2) to study important factors to construct a business process support system in a mobile setting. Consequently, this thesis consists of the following two research artifacts. LÄS MER
5. Multirate Schemes and Multiuser Decoding in DS/CDMA Systems
Sammanfattning : Direct-Sequence Code Division Multiple-Access (DS/CDMA) has for some yearsbeen considered as a candidate for future personal and mobile communications.The reasons are mainly the properties of universal frequency reuse andthe multi-path mitigation. LÄS MER
