A workflow in ubiquitous computing environments must represent context information on transition constraints to support context-aware services. Moreover, it requires web service interfaces, which are independent of heterogeneous platforms, protocols, and languages. In this paper, we present uWDL, which is a workflow description language based on web services for ubiquitous computing and provide...

The analysis of a birth-death process using the z-transform was recently reported for processes having fixed transition probabilities between states. The current report extends that analysis to processes having transition probabilities that can differ from state to state. It is then shown that the model can be used to study practical queuing and birth-death systems where the arrival, birth, ser...

Succeeding under Medicare's enterprise Comprehensive Care for Joint Replacement Model will require collaboration among caregivers and financial arrangements to align incentives Priorities for most organization's transition to becoming a value-based hospitals will be care redesign, supply-purchasing strategy, and post-acute care provider partnering. Pursuing value for your joint replacement prog...

Today’s hospital leaders must manage to existing incentives while preparing for future challenges, such as the shift from fee for service to pay for performance, the transition toward more integrated care delivery and population health management, and the adoption of more patientcentric models of care delivery and management. This transition comes at a time when unemployment rates are high, fin...

Source address transition technologies, such Network Address Translation and Proxy, can be used to provide unauthorized private address space. The source address of packets originated in the private address space will be changed by NAT gateway or proxy server, which is hard for service providers to manage the edge network and trace source of attacks. This paper presents the source address trans...

The transition from the paediatric to the adult service is a complex process that requires early planning to prepare young adults and their families for the transfer to the adult hospital. The article outlines the main principles of the successful transition period. Importantly, a young adult becomes an independent individual, interacts with medical professionals independently, and makes the ap...

There is good evidence that morbidity and mortality increase for young persons (YP) following the move from paediatric to adult services. Studies show that effective transition between paediatric and adult care improves long-term outcomes. Many of the issues faced by young people across subspecialties with a long-term condition are generic. This article sets out some of the obstacles that have ...

Building on experience with a general-purpose notification service, we describe the design and implementation of a second-generation content-based messaging system. Elvin4 includes a novel security framework, internationalisation, a powerful subscription language, and a modular pluggable protocol stack. We discuss its evolution from previous versions, differences from related work, and describe...

The research presented in this paper is oriented on the transition of the manufacturing industry towards the delivery of product-service system. The paper presents the first results in the development of a decision support system dedicated to help in configuring service-oriented production systems, notably with an objective of capacity management. An illustrative case study is presented, linked...
