In Service Oriented Architecture (SOA), service composition integrates existing services to fulfill specific tasks using a set of standards and tools. However, current service composition techniques and tools are mainly designed for SOA professionals. It becomes challenging for end-users without sufficient service composition skills to compose services. In this paper, we propose a framework tha...

1HE PURPOSE OF THIS ARTICLE is to present useful information and suggestions that have been found of practical value in a general hospital in dealing with problems arising from accidental, suicidal, and industrial intoxication. This material is based on background experience gained in the laboratory of Dr. A. 0. Gettler, Chief Toxicologist to the Medical Examiner of the City of New York, and in...

Web services composition allows a software designer for combining atomic services, for instance taken from a marketplace, in a complex business process fulfilling a desired functional goal. Moreover, among a large number of possible compositions, the designer may want to consider only those which satisfy specific non-functional requirements. In our work we consider verification of security prop...

In this paper, we describe an OPNET model of a General Packet Radio Service (GPRS) network. The model captures the signaling and transmission behavior of the GPRS network. We first introduce a GPRS network and describe the signaling and transmission procedures that will be modeled. In order to point out the simplifications made in the OPNET model, we then address the differences between the GPR...

Complications of medical care occur as a consequence of both the illness and the treatment. As such, we must question whether errors in the provision of care should be judged in the same light as complications attendant on the disease being treated. The use of quality assurance methods has focussed on continuing to define and decrease complications as a way of improving outcomes. The article by...

This paper derives exact results for a polling system such as a token bus or token ring with exhaustive service and priority polling. The results can also be used to analyze a terminal controller with a general-service order table. There are N stations in the system and the token is passed among them according to a polling table of length M (>N). Stations are given higher priority by being list...

In this paper we proposed dynamic adaptive guaranteed quality-of-service (QoS) provisioning scheme over General Packet Radio Service (GPRS) wireless mobile links. The guaranteed QoS media access control (GQMAC) protocol and the accompanying adaptive prioritized-handoff call admission control (AP-CAC) protocol are used to maintain QoS guarantees. The effect of mobile handoffs are also taken into...

background: implementing community-based psychiatric services is one of the priorities of the who/emro mental health programs. this study presents an aftercare service, as a community based-service, for patients with severe mental illness (smis).   methods : in this randomized controlled clinical trial design, 176 patients, who attended selective hospitals with smi, were allocated into three gr...
