While the Internet's human-facing side is undergoing the Web 2.0 revolution, the machine- facing side is likewise experiencing a major transformation-from an application-based to a service-oriented architecture-both within and across enterprise boundaries.
The remote sensing information service grid node (RSIN) is a tool for dealing with climate change and quantitative environmental monitoring. Based on the high-throughput computing grid, RSIN enables a workflow management system for data placement. The accompanying unified data-and-computation-schedule algorithm helps load balancing between and within workflow steps.
Radio-frequency identification technology provides promising benefits such as inventory visibility and business process automation. However, if companies are to realize these benefits, researchers must address major challenges such as data processing, integration architecture design, security, and privacy.
Parsing is an expensive operation that can degrade XML processing performance. A survey of four representative XML parsing models-DOM, SAX, StAX, and VTD-reveals their suitability for different types of applications.
NAREGI's middleware stack provides comprehensive support for coupled applications in the nanoscience discipline. The authors describe several mechanisms that are application-area agnostic and can be applied to other disciplines, such as weather and climate simulations, multiresolution simulation in life sciences, and other complex systems.
Translational research projects target a wide variety of diseases, test many different kinds of biomedical hypotheses, and employ a large assortment of experimental methodologies. Diverse data, complex execution environments, and demanding security and reliability requirements make the implementation of these projects extremely challenging and require novel e-Science technologies.
The Land Information System (LIS) is a multiscale hydrologic modeling and data assimilation framework that integrates the use of satellite and ground-based observational data products with advanced land-surface modeling tools to aid several application areas, including water resources management, numerical weather prediction, agricultural management, air quality, and military mobility assessment.
Through the development of new classes of software, algorithms, and hardware, data-intensive applications provide timely and meaningful analytical results in response to exponentially growing data complexity and associated analysis requirements.
Timing is everything. Neurons fire in time-locked fashion to propagate signals and form memories. The cell division cycle, the process by which an adult cell divides into two daughter cells, is carefully orchestrated by rises and decays of regulating protein concentrations. Engineered systems, like data centers, also involve temporal coordination. A few months back, the music service Last.fm had to...
Hierarchical graphs provide a data structure to support a programming model that aims to improve understandability by creating an architectural basis for building inspectable systems.We engage developers in constructing and exposing a runtime model of a system in a clear and structured way, thereby enabling them to build inspectable systems. This approach rests on the intuition that by supporting...
The GQM+Strategies approach extends the goal/question/metric paradigm for measuring the success or failure of goals and strategies, adding enterprise-wide support for determining action on the basis of measurement results. An organization can thus integrate its measurement program across all levels.
What happens if you combine the virtues of software engineering with database engineering? Developers managing the evolution of data-intensive software systems face numerous crucial challenges.
An analytic methodology involving modeling and simulation could help decision makers determine how their employees' use of social networks impacts their organization, identify how to mitigate potential risks, and evaluate the financial and organizational implications of doing so.
An experimental open, cloud-based platform for large-scale, low-cost delivery of healthcare applications enables broader use of patient-centric management of electronic health records and facilitates the secure and seamless sharing of EHRs among stakeholders within a healthcare system.
Collaboration across research, government, academic, and private sectors is integrating more than 70 scientific computing libraries and applications through a tailorable provenance framework, empowering scientists to exchange and examine data in novel ways.
Data mined from satellite imagery could serve as an early indicator of socially disruptive events like epidemics, especially in countries with limited surveillance resources.
Great progress has been made in standardizing 2D medical images, but the standardization of 3D medical models is still lacking. The first Web extra at http://youtu.be/J_h3Pcono7A is a video in which a shoulder muscle is rendered based on a fresh cadaver and then laid out on a computer. The pattern is then applied to a 3D model of a shoulder, with corresponding muscle layers and connections to the...
More varied data channels, increasingly diverse analytic methods, and new deployment models--along with some fundamental technology shifts--will significantly impact the next generation of big data systems.
