Helium leads to geothermal energy resources: When we think about alternative sources of energy, we often forget the potential of geothermal energy resources. In fact, it has been estimated that accessible geothermal energy in the U.S. represents 90 quadrillion kilowatt-hours or 3,000 times the country's total annual energy consumption. So far, it has been difficult and...; Tags: Earth, Researcher, Fluid, Energy, Arizona State University, Energy Resource, Web Site Development, Productivity, Web Technology, Internet, Roland Piquepaille; Blog posts 2007-12-02

Functionality-Based Service Matchmaking for Service-Oriented Architecture: Service matchmaking is a basic feature of Service-Oriented Architecture SOA. In this paper, a semantic-based flexible service matchmaking approach is presented to efficiently identifying functionality-compatible services. This approach utilizes SAWOWL- S to specify the service advertisements and service discovery requests. The functionality-compatibility of a service to a request is defined...; Tags: SOA, Matchmaking, Arizona State University, Service Matchmaking, Service-Oriented Architecture (SOA), Web Services, Middleware, Enterprise Software, Software; White papers 2006-12-23
WERCCS: A Client-Side Component Workflow Framework Using AJAX: The evolution of web application frameworks has led to embedded workflow engines, where user actions are mapped to sequences of web screens. Client-side rendering technologies such as AJAX Asynchronous Javascript And XML and Flash have improved responsiveness of web applications, enhancing the user experience. This paper presents WERCCS, a framework...; Tags: Web, Web Application, Arizona State University, WERCCS, AJAX, Internet, Software/Web Development, Web Development, Web 2.0; White papers 2006-11-07
Testability of Software in Service-Oriented Architecture: Service-Oriented Architecture SOA is a system architecture in which a collection of loosely coupled services communicate with each other using standard interfaces and message-exchanging protocols. As an emerging technology in software development, the SOA presents a new paradigm, and it affects the entire software development cycle including analysis, specification, design,...; Tags: SOA Software Inc., SOA, Arizona State University, Service-Oriented Architecture (SOA), Web Services, Software Development, Middleware, Enterprise Software, Software, Software/Web Development; White papers 2006-06-29
Introduction to Service-Oriented Computing: The Service-Oriented Computing SOC paradigm refers to the set of concepts, principles, and methods that represent computing in Service-Oriented Architecture SOA in which software applications are constructed based on independent component services with standard interfaces. The main idea of SOC/SOA is to explicitly separate software engineering from programming, to emphasize...; Tags: Software Engineering, Computing, Arizona State University, SOC, Tools & Techniques, Service-Oriented Architecture (SOA), Development Tools, Management, Web Services, Enterprise Software, Software, Software Development, Software/Web Development; White papers 2006-04-21
GMP: Distributed Geographic Multicast Routing in Wireless Sensor Networks: This paper proposes a novel Geographic Multicast routing Protocol GMP for wireless sensor networks. The proposed protocol is fully distributed and stateless.
