With the advent of Web 2.0, users now expect to be able to customise, edit and share information from any online device. These capabilities are unavailable in many geographic information applications and where it is, it is far too difficult to use. Satellite navigation devices and software are also not flexible enough in this regard. Current satellite navigation technology enables users to view maps and navigate easily. However, it does not support information sharing and marking-up maps with symbols other than routes and locations. Currently, a popular desktop solution to this problem is Web 2.0 Mashups, which enable implementers to correlate information from several web data sources into one coherent application. Mashups also have their caveats, as they are beyond the capabilities of lay users and, being web-based, they are not location aware and do not support mobility. This paper presents Mobile Collaborative Mapping (MCM), a browser-based location-aware collaborative map editor to address these shortcomings through a simplified editing system and revision based storage server and discusses its application in an e-Science scenario of use and the capabilities of the current MCM prototype.

Mobile computing allows for the development of new and sophisticated database applications. Such applications require the reading of current and consistent data. In order to improve data availability, increase performance and maximize throughput, data replication is used. However, due to inherent limitations in mobile and other loosely-coupled environments, the concurrency control and replica control mechanisms must be revisited. This paper proposes a new protocol that guarantees the consistency of replicated data in a mobile computing environment, while provide high data availability and ensure an eventual replica convergence towards a strongly consistent state.

In this paper, we report on implementing an experimental distributed computing application for bioinformatics consisting of basic high-performance computing environments (Grid and PC Cluster systems), multiple interfaces at user portals that provide useful graphical interfaces to enable biologists who are not IT specialists to benefit directly from the use of high-performance technology.

In this short paper, we present our solution to index, store and retrieve the domain knowledge. The main principle exploits Lucene to index the domain knowledge under guide of the domain schema. The method to map domain knowledge structure into Lucene index structure, store and update the indices, and to transfer RDF-based query into Lucene's query are presented. Copyright 2007 acm.

Central to grid processing is the scheduling of application tasks to resources. Schedulers need to consider heterogeneous computational and communication resources, producing the shortest possible schedule under time constraints dictated by both the application needs and the frequency of fluctuation of resource availability. This paper introduces a set of schedulers with such characteristics. Copyright 2007 acm.

We propose a remote file system for use in desktop grid applications. The proposed system provides programs with the ability to query and update files on remote machines without requiring any changes to the program code. The system (a) generates a profile of the program file operations and (b) uses the profile to implement collective and pre-fetched I/O. Copyright 2007 acm.

Updating legacy applications to let them properly run in a Grid environment generally requires a noticeable development effort. The approach proposed in this work is intended to reduce this effort through the automated generation of aspects that, once incorporated into legacy applications, ensure integration with the Globus Grid environment. The generated aspects encapsulate concerns handling the interaction with Globus services, thus keeping the relevant code separated from application classes. Copyright 2007 acm.

In this paper, we propose a representation of controllers that uses high-level sensors and possesses a general and intuitive structure that offers several types of parameters, which can be modified by the animator or automatically. This structure, with the feedback signals provided by its sensors, allows several state machines to act simultaneously on the model, or in a subset of its actuators. The sensors can be optimized, facilitating their definition and use. The representation also permits the animator to define procedures with more general instructions in order to be automatically executed by the controller during the dynamics simulation.

Self-healing is one of the main challenges to growing autonomic pervasive computing. Fault detection and recovery are the main steps of self-healing. Due to the characteristics of pervasive computing the self-healing becomes difficult. In this paper, the challenges of self-healing have been addressed and an approach to develop a self-healing service for autonomic pervasive computing is presented. The self-healing service has been developed and integrated into the middleware named MARKS+ (Middleware Adaptability for Resource discovery, Knowledge usability, and Self-healing). The self-healing approach is being evaluated on a test bed of PDAs. An application is being developed by using the proposed service. Copyright 2007 acm.
