The Beginning, The Middle, and The End: New Tools for the Scholarly Edition

This article discusses a set of prototypes currently being designed and created by the Interface Design team of the Implementing New Knowledge Environments (INKE) project. These prototypes attempt to supplement the user experience in reading digital scholarly editions, by supporting a set of tasks that are straightforward in a digital environment but in a print edition would be sufficiently more difficult as to be prohibitive. We therefore offer these experimental prototypes as a collection of new affordances for the scholarly edition, although they may reasonably be extended, with some variation, to other kinds of digital text

Establishment of a hydrological benchmark for mitigating urbanisation impacts at Logan Village, South-east Queensland

Estimation of flow in ungauged catchments is a difficult task as estimated flow cannot be verified directly due to the absence of recorded flood data. This paper presents a case study for the Quinzeh Creek catchment at Logan Village, South-east Queensland which includes detail flood estimation method to develop management strategies for mitigating flooding impact of urbanising upstream Yarrabilba catchment (area 20 km2). Subdivision in 1985 of some areas at Logan Village ensured all the building footprints were above the flood planning standard of 2% Annual Exceedance Probability (AEP) flood event. In 2011, the Logan City Council (LCC) released 1% AEP flood map for three reasons, namely Queensland State's Policy, Queensland Flood Inquiry Commission's recommendations and amalgamation of three different Planning Schemes. Additional properties are predicted to be affected by the 1% AEP flood map, which resulted in an unsatisfied community due to a perceived impact of this new food map on the property values and insurance premiums. The community is also concerned about flooding impacts of urbanising the upstream rural parts of the Yarrabilba catchment. The developer of Yarrabilba is committed to implementing a 'non-worsening' strategy of flood mitigation. However, the accurate flow estimation for pre-developed condition is critical for development of effective mitigation measures for the urbanisation impacts. Therefore, review of flow estimation for the pre-developed case was undertaken to establish a hydrological benchmark for the mitigation measures. The developed hydrologic model was compared with the ARR 1987 Rational Method and the ARR Regional Flood Frequency Estimation (RFFE) Model 2012 (alpha version). It was found that the ARR RFFE Model 2012 provides much higher flood quantile estimates than the rainfall-based method; however, due to lack of observed flood data the results of the adopted methods could not be independently verified. Updated hydrological benchmark along with a proposed local gauging station in Quinzeh Creek is expected to provide a greater confidence in the flood mitigation strategy among the professionals and the local communities. This approach is expected to provide valuable hydrological insights for other similar catchments

MAC protocol for indoor optical wireless networks

Optical wireless communication has emerged as a promising candidate for future high data rate indoor applications such as virtual reality. Even though physical layer of optical wireless networks has rapidly developed during last decade, upper layer architecture that harness the physical layer capabilities has not yet been developed in the same pace. To this end, the authors develop a novel contention-based medium access control (MAC) protocol that accompanies a service differentiation mechanism and a dynamic contention window tuning algorithm. The proposed service differentiation mechanism can identify the diverse traffic types and facilitate their throughput and delay requirements. To add more robustness to the contention-based MAC protocol which depends on contention windows to avoid collisions, the authors also propose an algorithm that dynamically changes the contention window sizes to suit the congestion level. They analyse the performance of the proposed MAC protocol under diverse network configurations and they show that it is far more effective to use end-user network metrics such as throughput in dynamic adaptation algorithms in addition to collision rate due to the wide range of traffic types present in the network. The proposed results demonstrate that the proposed MAC protocol can handle next-generation traffic types and their stringent latency requirements in an effective manner

Indoor optical wireless access networks-recent progress [Invited]

© 2020 OSA. Optical wireless access networks have seen rapid progress. With beam-steering capability, optical wireless communications can deliver very high capacity, support user mobility with indoor localization supported directly at the optical layer, be resilient against the blocking of beams by exploiting spatial diversity at the optical layer, and guarantee low-latency links with modified protocols and network architectures. This paper presents a review of recent progress in achieving functions of communication, localization, resiliency, and dynamic networking using optical-layer techniques
