We examined the nature of the referral patterns in the email telemedicine network operated by the Swinfen Charitable Trust with a view to informing long-term resource planning. Over the first six years of operation, 62 hospitals from 19 countries registered with the Trust in order to be able to refer cases for specialist advice; 55 of these hospitals (89%) actually referred cases during this pe...

BACKGROUND Teledermatology may be less optimal for skin neoplasms than for rashes. OBJECTIVES We sought to determine agreement for skin neoplasms. METHODS This was a repeated measures study. Each lesion was examined by a clinic dermatologist and a teledermatologist; both generated a primary diagnosis, up to 2 differential diagnoses, and management. Macro images and polarized light dermoscop...

N umerous studies comparing store-andforward (S&F) teledermatology with conventional, face-to-face care have shown several advantages of S&F teledermatology, including improved patient access, comparable diagnostic accuracy, costeffective care, and remote medical education. However, despite these reported benefits of teledermatology in the medical literature, the pace of adoption for S&F telede...

Production of high quality digital media is increasing in both the commercial and academic world. This content needs to be distributed to end users on demand and efficiently. Initiatives like CineGrid [1] push the limit looking at the creation of content distribution centres connected through dedicated optical circuits. The research question of this project is the following: “What is the optima...

In the evolution of wireless networks such as wireless sensor networks, mobile ad-hoc networks, and delay/disruption tolerant networks, the Store-Carry-Forward (SCF) message relaying paradigm has been commonly featured and studied with much attention. SCF networking is essential for offsetting the deficiencies of intermittent and range limited communication environments because it allows moving...

Store-and-forward MTA relaying servers have frequently presented problems to various antispam techniques, such as IPbased reputation or email authentication. Algorithms that find email relaying servers can use knowledge about a domain’s outbound IP addresses combined with cryptographic domain authentication frameworks such as DomainKeys. This paper presents one such algorithm. 1.Why find relayi...

In this paper we develop an analytic model for end-to-end communication protocols and study the window mechanism for flow control in store-and-forward (in particular message-switching) computerbased communication networks. We develop a static flow control model in which the parameters of the system are not dynamically adjusted to the Paper approved by the Editor for Computer Communication of th...
