    This paper is a study of digital identity management system with specific emphasis on its implementation using a set of credentials. In our study we propose a credentials attributes mapping technique, the so-called common attributes mapping (CaMa) which facilitates the extraction of useful features to be represented in composing an identity. The study also groups credentials of similar types and i... View full abstract»

    We describe a low-cost, versatile microstrip antenna to be used for terrestrial to satellite fixed and mobile point to point links at Ku-band. The Ku band has attracted a great deal of attention in North America and Europe due to the available wide bandwidth and the propagation range, which has enabled it to be used for terrestrial and terrestrial-to satellite links. This makes it particularly att... View full abstract»

  • Adapting Model for Convergence of Optimal MINMAX Bit Allocation in INTRA-Frame Video Coding

    Publication Year: 2008, Page(s):24 - 29
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (311 KB) | HTML iconHTML

    The application of optimal bit allocation in real-time video encoders is a challenging prospect for dependent macroblocks (MBs) where a quantiser is ascribed to each MB within a frame. The operational rate-distortion (R-D) convex hull of INTRA encoded frames may be approximated with a power-law function. However, discontinuities on the surface produce local divergence and therefore an adapting mod... View full abstract»

    Third generation (3G) cellular networks are being implemented in many countries at high rate. Due to the fact that manual cell planning is a time consuming process and prone to a degree of error and inefficiency, there is a need for automated approaches to optimise coverage, capacity and quality of cellular networks in a fraction of the time. This paper studies the application of genetic algorithm... View full abstract»

    Random pairwise key pre-distribution schemes have been adopted widely as a favored approach to pairwise key agreement problem in distributed sensor networks (DSNs). However, regardless of the recent security improvement efforts of their variants, they are still susceptible to several types of attacks including large-scale node capture, threshold collusion ones and expose undesirable properties. Ex... View full abstract»

    Electroencephalography (EEG) can be used as an indicator of fatigue. Several studies have shown that slow wave brain activities, delta (0-4 Hz) and theta (4-8 Hz), increase as an individual becomes fatigued, while the fast brain activities, alpha (8-13 Hz) and beta (13-35 Hz), decrease. However, an EEG is a complex piece of equipment that is generally used in laboratory based studies. In order to ... View full abstract»

    Structural health monitoring is a vital part in the management of bridges, particularly as the structures begin to age. Detecting structural faults through the use of sensors is an emerging field that has seen considerable efforts this past decade. Similarly, the use of sensors in bridge management systems provides valuable data on the condition of bridges and external factors affecting the deteri... View full abstract»

    Wireless mesh networks (WMNs) have become a better alternative for extending wireless Local Area Networks (WLANs) to provide network coverage up to the furthest of far flung rural areas. This has been implemented by using a meshed backbone network interconnecting the mesh access points (MAPs) that manages each of the WLANs. The routing algorithms use the mesh backbone to establish inter-WLAN route... View full abstract»

    In this paper we study a two access point (AP) providers' price competition in a wireless mesh network (WMN). The two AP providers offer IP-based service for possibly different prices and quality-of-service (QoS) in terms of mean packet delay. The end-users' choice between the APs is based on their compensated utility. We consider a two stage game among the two AP providers and their end-users. In... View full abstract»
