4,4′‐Methylenedianiline (MDA) is utilized to produce high temperature epoxy resins as well as other high‐performance composites; however, MDA is a known carcinogen and liver toxicant. Novel dianilines derived from both petroleum and biomass with different quantities and types of methyl and methoxy substituents on the aromatic ring were prepared and studied to reduce toxicity and carcinogenic aspects...
The adoption of IT-based interfaces to monitor and control telco capabilities is a consolidated approach. In such a scenario the end-users design composite services that orchestrate functions implemented through one or more resources managed by telecom operators. In addition to the issues that have to be faced to support the design of composite services in general, in this case it is also necessary...
The high availability of information provided through standards typical of the Web 2.0 world (e.g. RSS feed, atom, etc.) and services exposed by means of Web service API (see [1] for a list of more than 1300 APIs) leads to the development of new tools for the rapid creation of applications-called mashups-that combine these different sources. More specifically we refer to the event driven class of...
The diffusion of Telco/IT Mashups, i.e., those service compositions that combine data sources and telecom services, seems to require the development of appropriate ecosystems in which small size companies, called ??3rd Parties??, ideate, implement and deploy the Mashups and make them available to end users through Service Delivery Platform operated by platform operators. While from the technical point...
In this paper we present the results of a set of experiments aimed at measuring the performance of Event Driven Mashup orchestrators. We show four different orchestrator implementations, one based on BPEL, one based on a plain Web Service, one based on a JSLEE container and one based on a fully distributed scheme. We show that most of the orchestration activity is spent in Web Service processing,...
