The paper discusses the merits of having a reconfigurable access network. The network is viewed as a stack of logical PONs in which bandwidth can be redistributed on an inter-PON scale. The redistribution allows for optimal distribution of bandwidth to the end user.

Introduction Direct intramyocardial therapies aimed at treating myocardial regions affected by severe ischemia may benefit from CMR-guided interventional procedures. Although interventional MR approaches using active devices are considered to be the method of choice, potential tissue heating and altered mechanical properties are some of their limitations. Methods that have the capacity to visua...

We report on an emerging application focused on the design of resilient long reach passive optical networks using combinatorial optimisation techniques. The objective of the application is to determine the optimal position and capacity of a set of metro nodes. We specifically consider dual parented networks whereby each customer must be associated with two metro nodes. An important property of ...

The hybrid (Optical-Wireless broadband) network with the backbone as optical networks, Passive Optical Networks (PON), and wireless access networks have been proposed to provide good Quality of service (QoS). A Dynamic network solution for adopting both wired and wireless networking methods need to be updated. A Multicast based network coding technique is introduced for improving total network ...

by Nicholas E. Kottenstette This dissertation shows how to develop wireless networked embedded control systems (wnecs) in which the controller and the plant are isolated and can only interact over a wireless network. Many of the new results presented are based on passivity and scattering theory. In particular we show how to: 1. synthesize discrete time passive, strictly-input passive, and stric...

A hybrid OFDM-baseband (BB) signal and three-band OFDMwireless channels using the 2.5 GHz bandwidth directly modulated laser and 10 GHz bandwidth electroabsorption modulated laser in a passive optical network (PON) is investigated. Each 16-QAM OFDM wireless and 64-QAMOFDM-BB signals can achieve 11.2 and 15 Gbit/s traffic data rates, respectively, in 20 km fibre transmissions. Moreover, the netw...

intelligence in animals, which are based in the capacities for self-organization in brain dynamics. Furthermore, voiceor motionactivated surveillance recorders can be triggered by prescribed inputs to limit their scope of intake, but once their gates are open, transcription is passive and representational, not active or meaningful. What is missing from passive devices is the goal-directedness c...
