The increasing diversity of end-devices used by users to access their applications and systems strengthens the need for device-independent methods for implementing these applications. The Device-Independent Architecture (DIA) is one of the available approaches to this problem, but it does not directly address the issue of user interface (UI) device-independency. This issue can be addressed by real-time...
In this paper, we develop an approach to preserve validity of executable batch-job specifications during changes at run-time based on Petri-nets. The approach in particular supports changing batch-job specifications while they are being executed, which makes it particularly important to ensure that the change preserves the critical properties. The approach supports verification of the batch-job specifications...
To address shortcomings of the current Internet, many researchers are taking a clean-slate approach toward re-designing the Internet. These so-called clean-slate approaches discard the old assumptions, design principles, and constraints of the current Internet, set aside concerns about compatibility with existing software, and rebuild the entire network from scratch. Clean-slate approaches have the...
Last technological advances have brought drastic changes affecting the way distributed systems are conceived. Designers have to tackle the fact that applications could be controlled by different end users on diverse computing platforms in assorted environments. However, these kinds of facilities only make sense when they are ruled by the well-known group awareness. It is necessary to devise new mechanisms...
Distributed architecture is a fundamental way for science and engineering data application by aggregate power of computing resources connected by networks of the grid. This paper describes a innovative scenarios for intensive rainfall data analysis. The Flood Early Warning System is performed to give an alert in advance about the occurrence of heavy rainfalls around the world. The aim of the project...
We propose a global system for acquisition, maintenance and communication of achievements in the real-world. The main focus of the proposal lies on a context-aware notification service for achievements. Users of the system can browse the achievement web application and will only get notifications of users within the same context. The definition of context is based on the network infrastructure of...
This paper develops a client-side context-aware search application which is built on the context-aware infrastructure. A context-aware architecture is designed to collect the mobile user's context information, derive mobile user's current context, distribute user context among context-aware applications, and support the context-aware applications. The context acquisition is centralized at the context...
