OBJECTIVE To review the effect of a vascular access team on the incidence of central line-associated bloodstream infections in infants admitted to a neonatal intensive care unit. DATA SOURCES MEDLINE, CINAHL, Embase, Web-of-Science and the Cochrane Library were searched until December 2013. STUDY SELECTION Studies that evaluated the implementation of a vascular access team, and focused on t...

The networking technologies used in industrial automation are required to support real-time performance guarantees to ensure that sensor/command data reach target nodes within a delay bound. With the continuing popularity and thus the accompanied price drop of the Ethernet technology, replacing the typically closed and proprietary automation networks with Ethernet is emerging as a very attracti...

A non-cooperative game theoretical approach for analyzing opportunistic spectrum access in cognitive radio environments is proposed. New concepts from computational game theory are applied to spectrum access analysis in order to extract rules of behaviour for an emerging environment. In order to assess opportunistic spectrum access scenarios of cognitive radios, two oligopoly game models are re...

This memo is a digest of the user network interface specification of NTT Communications’ dual stack ADSL access service, which provide a IPv6/IPv4 dual stack services to home users. In order to simplify user setup, these services have a mechanism to configure IPv6 specific parameters automatically. The memo focuses on two basic parameters: the prefix assigned to the user and the addresses of IP...

In this paper suitable MAC protocols for the implementation in PLC access networks are studied. We propose a logical model for the investigation of the MAC layer according to the applied transmission methods in the PLC systems and to the used telecommunication services. The impulsive noise has a big impact on the error behavior of the transmission, but there are various possibilities to do deal...

A telecommunications community cooperative (TCC) is an autonomous association of individuals, who join forces to respond to common economic, social, and cultural needs and aspirations through a jointly owned enterprise, democratically governed and managed. In Argentina, TCCs were created by community-conscious members to fill in for the State when it was the State was unable to provide telephon...

Wireless LAN technology is complementary to 3G systems and could be used to provide high bandwidth hot spot coverage, for example in railway stations and offices, in order to provide the high bandwidth video and broadband services such as those emerging on DSL fixed access. The IST Projects BRAIN and MIND have investigated a number of key technical enablers for such a “system beyond 3G”. These ...

AbstractWe propose a dial-up optical access architecture that allows an end host to dynamically request and receive a high-speed circuit for connection to its Internet Service Provider’s router. We carry out an analytical comparison of the current leased-line architecture and our proposed dial-up architecture for access networks. It shows significant capacity savings, for example, savings of 39...

Four experiments with undergraduates used illusory line motion (ILM) to contrast Z. W. Pylyshyn's (1989) FINST theory of spatial indexing with predictions made by unitary attention models. Multiple-onset stimuli were able to cause ILM at disparate, noncontiguous spatial locations. Consistent with gradient explanations of ILM and with FINST theory predictions, varying line-drawing speed and the ...
