The last years have seen dramatic changes in the way the world stores, manages, and uses its data. Whereas the end of the previous millennium saw an emphasis on decentralized, desktop-based storage and manipulation of data, we are now seeing information technology returning in great part to a model of centralized, professionallymanaged computation and data delivery services, using increasingly ...

In the big data era, the scientific community is in need of better practices and infrastructures for data deposition and sharing. In addition, scientific journals are challenged with formulating, implementing, and enforcing commonly accepted data deposition guidelines and addressing problems associated with the use of proprietary data. Furthermore, new publication formats are required to specif...

Mobile devices, such as smartphones and tablets, are useful tools for in situ gathering information about spatial locations. Specialists need mobile geographical data acquisition and validation systems to be used in fieldwork and in places where there is limited or any network connectivity available. This paper presents an ongoing work on designing and implementing a hybrid architecture for thi...

The publish/subscribe communication model is increasingly considered for implementing middleware infrastructures for widely distributed applications. Scalability issues and routing algorithms of such systems have recently been the focus of intensive research. So far little attention has been given to security and management issues. In current publish/subscribe systems, malicious publishers can ...

Advances in genomic medicine have the potential to change the way we treat human disease, but translating these advances into reality for improving healthcare outcomes depends essentially on our ability to discover disease- and/or drug-associated clinically actionable genetic mutations. Integration and manipulation of diverse genomic data and comprehensive electronic health records (EHRs) on a ...

Integration of information and communication technologies with the traditional of electric power infrastructures and creation of an interoperable, scalable, and flexible smart grid will require numerous technological innovations and advancements. The purpose of this paper is to take a detailed look at the various technologies which may be utilized in the data transmission for the smart grid and...

Existing commercial and research event-based middleware are limited in their ability to evolve in order to support the requirements of novel applications. As a result, new infrastructures are being proposed to attend to widening scope and changing demands. In this paper, we define the concept of versatility generally and survey existing approaches that can be used to develop and preserve versat...

English Abstract Generating and maintaining user access to resources like e-learning courses is a time and money consuming process for both, users and resource providers. In authentication and authorization infrastructures such as Shibboleth, PAPI and Liberty Alliance, home organizations authenticate their own users and provide a set of user information attributes to the resources they access, ...

As large grid infrastructures, such as Enabling Grids for E-sciencE, mature, they are being used by scientists around the world in their daily work, running thousands of concurrent computational jobs and transferring large amounts of data. The successful and sustainable operation of such grid infrastructures is only possible through the use of monitoring tools. The underlying networks upon whic...
