Enterprise applications implement business resource management systems, customer relationship management systems, and general systems for commerce. These applications rely on infrastructure that represents the vast majority of the world’s computing resources. Most of this infrastructure is lightly utilized and inflexible. This paper considers the role of Grid technologies in increasing the util...

The paper describes design and implementation of software infrastructure for building augmented reality applications for ubiquitous computing environments. Augmented reality is one of the most important techniques to achieve the vision of ubiquitous computing. Traditional toolkits for augmented reality provide the high level abstraction that makes it easy to build augmented reality applications...

Abstract: We describe a component-based infrastructure for Web-based applications that reduces the need for We describe a component-based infrastructure for Web-based applications that reduces the need for custom integration. We assume that to construct an application, users will give a specification of three kinds of components: data source, business analysis, and visualization unit. From this...

Abstract The morphology of urban green infrastructure (UGI) will affect the quality environment and way people perceive. three-dimensional morphological features UGI have been proven to be key factors effect ecological environment, which rarely incorporated into in previous researches. In this paper, a systematic approach develop 3D spatiotemporal database for is proposed. built on complete set...

RTI, under a contract with the U.S. Environmental Protection Agency (EPA), has developed a Web-based ArcIMS application, called the Web-Based Reach Indexing Tool (WebRIT). WebRIT is used to create, validate, and update National Hydrography Dataset (NHD) reach indexes, latitude/longitude coordinates, and other locational data. The initial version of WebRIT used a traditional ArcIMS architecture,...

Service-Oriented Architecture (SOA) has drawn significant attention recently, and numerous architecture approaches have been proposed to represent SOA-based applications. The architecture of SOA-based applications is different from traditional software architecture, which is mainly static. The architecture of an SOA-based application is dynamic, i.e., the application can be composed at runtime ...
