  1. 1. The G-Word : Virtuosity and Violation, Negotiating and Transforming graffiti

    Författare :Jacob Kimvall; Magdalena Holdar; Hans Hayden; Håkan Nilsson; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Graffiti; Graffiti Art; Street Art; Berlin Wall; Zero Tolerance; Hip-Hop; Art Institutions; Nolltolerans; Art History; Visual Analysis; konstvetenskap; Art History;

    Sammanfattning : Contemporary public discussions on graffiti are characterized by co-existence of contradictory claims. On the one hand graffiti is described as vandalism, and on the other as an artistic movement. LÄS MER

  3. 2. The alternate-phase return-to-zero modulation format in high-speed optical-fibre communications

    Författare :Marco Forzati; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed optical transmission; return-to-zero; nonlinear optics; dispersion management; phase modulation; modulation formats; Fibre optics communication; fibres;

    Sammanfattning : Increasing the channel bit rate is an efficient way to upgrade traffic capacity in installed transmission links. At bit rates of the order of 40 Gb/s, on-off keying transmission becomes severely impaired by non-linear effects,particularly Intra-channel Cross-Phase Modulation (IXPM) and Intra-channel Four-Wave Mixing (IFWM), which cause pulses in different bit slots to interact with each-other.

  4. 3. In the quest for a cold tolerant variety : gene expression profile analysis of cold stressed oat and rice

    Författare :Angelica Lindlöf; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cold tolerance; oat; rice; bioinformatics analysis; Bioinformatics; Bioinformatik; Technology; Teknik; cold tolerance; oat; rice; bioinformatics analysis;

    Sammanfattning : Cold acclimation is a process which increases the freezing tolerance of an organism, after exposure to low, non-freezing temperatures. The acclimation ensures that cold tolerant species can endure harsh winter conditions, by preparing them to sub-zero temperatures. LÄS MER

  5. 4. Phase Modulation Techniques for On-Off Keying in Optical Fibre Transmission

    Författare :Marco Forzati; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; return-to-zero; fibre optics communication; phase modulation; nonlinear optics; dispersion management; high-speed optical transmission; modulation formats; fibres;

    Sammanfattning : Increasing the channel bit rate is an efficient way to upgrade traffic capacity in installed transmission links. At bit rates of the order of 40 Gb/s, on-off keying (OOK) transmission becomes severely impaired by non-linear effects especially Intra-channel Four-Wave Mixing (IFWM) which limit the power at which the signal can be transmitted, and ultimately the transmission distance.

  7. 5. Continuous-Time Delta-Sigma Modulators for Wireless Communication

    Författare :Mattias Andersson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; return-to-zero; A D converter; loop delay; delta-sigma; ADC; CMOS; STF; continuous-time; sigma; delta; filtering; CT; RZ;

    Sammanfattning : The ever increasing data rates in wireless communication require analog to digital converters (ADCs) with greater requirements on speed and accuracy, while being power efficient to prolong battery life. This dissertation contains an introduction to the field and five papers that focus on the continuous-time (CT) Delta-Sigma modulator (DSM) as ADC. LÄS MER
