    Impact of PMD on Distributed Raman Amplifiers Using Modern Transmission Fibres

    The authors experimentally and numerically investigate Raman amplification and polarization mode dispersion PMD effects on a channel using two fibres of PMD coefficient 0.01pskm-1/2 and 0.1pskm-1/2 respectively. Two pumping configurations were employed to evaluate the signal gain and OSNR over a range of wavelengths. Using a Non-Return to Zero (NRZ)...

    SerViz: A Tool for Interactive Visualization of Web Service Collections

    Existing web service discovery techniques require the user to explore large web service collections to find specific web services. Thus, these techniques do not support the user in effectively discovering web services. Information visualization is proposed to overcome this problem but has not been widely applied to visualize web service...

    An Architecture to Support Multi-Touch Collaborative Information Retrieval

    Collaborative Information Retrieval (CIR) is the process by which people working together can collaboratively search for, share and navigate through information. Computer support for CIR currently makes use of single-user systems. CIR systems could benefit from the use of multi-user interaction to enable more than one person to collaborate using...

    Enterprise Architecture for Small and Medium Enterprise Growth

    A key constraint for growing Small and Medium sized Enterprises (SMEs) is the business skills required to grow the enterprises through the stages of transformation. Criticism against growth stage models for SMEs is of concern, since these models contain the typical knowledge that appeals to managers of small enterprises as...

    Compensation for Polarization Mode Dispersion in Multi-Channel System

    Intensity induced random varying birefringence leads to nonlinear Polarization Mode Dispersion (PMD) in addition to linear PMD. In this paper, the authors investigate the effect of nonlinear PMD on a sideband channels with respect to centre wavelength. It is shown that if three or more channels are launched in the...

    Determining the Rate of PMD Compensation in Deployed Aerial Optical Fibres Through SOP Monitoring

    In this paper, statistical distributions for First Order Polarization Mode Dispersion (FO-PMD) and Second Order Polarization Mode Dispersion (SO-PMD) are experimentally confirmed when measured using the FTB-5700 Single-Ended Dispersion Analyzer instrument for aerial optical fibres. The authors also determined the time scale over which to compensate FO-PMD in aerial fibres...

    The Influence of High First-Order Polarization Mode Dispersion Sections on Optical Network System Performance

    High First-Order Polarization Mode Dispersion (HiFO-PMD) sections are known to increase the overall First-Order PMD (FO-PMD) of an optical fibre link. Replacement of the HiFO-PMD regions with low-PMD fibres will drastically reduce the overall FOPMD of a fibre network link. In this paper, through simulation, the authors show that besides...

    Mobile and Context: Divide or Conquer?

    The interdisciplinary field of Human Computer Interaction (HCI), having barely matured past its adolescent shoes, now faces the challenge of meaningfully integrating Mobile Human Computer Interaction (MHCI). MHCI however, when viewed as an emerging independent discipline, does not have the luxury to leisurely plod along. Amid the great diversity of...
