Distributed systems for locating people and equipment will be at the heart of tomorrow's active offices. Computer and communications systems continue to proliferate in the office and home. Systems are varied and complex, involving wireless networks and mobile computers. However, systems are underused because the choices of control mechanisms and application… (More)
This paper presents a solution to the problem of connectiv-ity of portables to an ATM wired network in the in-building environment. The approach to the support of ATM reduces the mobility load on the wired ATM network and is compatible with standard signalling protocols. The system is pico-cellular with a large number of base stations. The base stations are… (More)
Thin-client systems are becoming favourable in today's computing, as today's working environment tends to be mobile and ubiquitous. Stateless-client systems not only conform to the thin-client paradigm, but also extend to free the client completely from preserving any system state. In the stateless-client systems, the application processing takes place in… (More)
UNLABELLED Clinical decisions regarding diagnosis and effective treatment of coronary artery disease frequently require integration of information from various imaging modalities, which are acquired, processed, and read at different physical locations and times. We have developed methods to integrate the information in 2 cardiac imaging studies, perfusion… (More)
Memory-mapped networks such as Scalable Coherent Interconnect (SCI) 5] and Memory Channel 4] ooer a new method for constructing network pe-ripherals by remoting a host's IO bus. This paper details our experiences from building such an endpoint, and examines how greater support may be provided.
This paper describes the Metrobridge project - a distributed switch for connecting PC cards via a high-speed ATM-style backbone network. Initially the system architecture is outlined, then certain aspects are examined in more detail. Topics discussed include learning and routing algorithms, access/routing control, management functions, and applications.
OBJECTIVE To describe inhaled nitric oxide (iNO) exposure in preterm infants and variation in neonatal intensive care unit (NICU) use. STUDY DESIGN This was a retrospective cohort study of infants, 22 to 33+6/7 weeks of gestational age (GA), during 2005 to 2013. Analyses were stratified by GA and included population characteristics, iNO use over time and… (More)
The rapidly advancing technology of cellular communication and wireless LAN makes ubiquitous computing feasible where the mobile users can have access to the location independent information and the computing resources. Multimedia networking is another emerging technological trend of the 1990s and there is an increasing demand for supporting continuous… (More)
Over the past 20 years, the Internet has grown from a small research network to a network of global importance. As Internet traffic continues to grow, the servers that provide the content must scale to be able to deliver the next branch of services, while remaining compatible with the millions of clients that already make use of them. Of central importance… (More)
