Automating the composition of web services is an object of a growing interest nowadays. In our former paper [3] we proposed a method for converting the problem of the composition to the problem of building a graph of worlds consisting of formally defined objects, and presented the first phase of this composition resulting in building a graph of types of services (an abstract graph). In this wor...

The Business Process Execution Language (BPEL) is a process modeling language which uses standard control constructs to define a process flow. But today enterprises have to be flexible and adaptable to cope with increasing change, uncertainty and unpredictability. Automating agile business processes is still a challenge as they are normally knowledge intensive, little automated but compliance r...

Web services are one of the most popular ways for building distributed Web Information Systems (WIS). In this paper we propose a distributed implementation of the Hera methodology, a methodology based on models that specify the different aspects of a WIS. The Web services used in the implementation are responsible for capturing the required data transformations built around specific Hera models...

Building Information Modelling (BIM) seeks to integrate information and business processes throughout the entire building life cycle. This technology is able to generate 3D models that semantically represent facility information dynamically over the life cycle of a building, but is limited when it comes to meeting the needs arising from the operation and management of facility services. There i...

We believe that the future consists of nomadic people depending upon mobile appliances using World Wide Web protocols to communicate with services offered in real world places. Use of web protocols provides a ubiquitous communication infrastructure and allows interaction with the multitude of existing web-based services. Part of the challenge to realize our vision is to bridge the physical and ...

Protected shared libraries are a new mechanism for building fast applicationextensible user-level operating system services. They extend notions previously found in dynamically linked shared libraries and thread migration to provide a new structuring model for operating system services. Early prototypes indicate that the performance of protected shared library services will be good, and that se...

Over the last three decades comprehensive research has been carried out trying to improve commissioning processes with powerful modeling tools and methodologies for data analysis and visualization. Typically addressed application scenarios are facilities management, contracting, special consulting services and measurement & verification as part of a certification process. The results are all bu...

Assessments of adaptation options generally focus on incremental, homogeneous ecosystem responses to climate even though climate change impacts can be big, fast, and patchy across a region. Regional drought-induced tree die-off in semiarid woodlands highlights how an ecosystem crash fundamentally alters most ecosystem services and poses management challenges. Building on previous research showi...

Ben Hardekopf, Taylor Riché, Jasleen Kaur, Jayaram Mudigonda, Michael Dahlin and Harrick Vin Laboratory for Advanced Systems Research Department of Computer Sciences The University of Texas at Austin Abstract This paper focuses on two questions: (1) how do properties of next-generation network services affect programmable router architectures and (2) how do properties of programmable router arc...

Given Senegal's limited resources, the country receives substantial support from externally funded partner organizations to provide family planning and maternal and child health services. These organizations often take a strong and sometimes independent role in implementing interventions with their own structures and personnel, thereby bypassing the government district health system. This artic...
