Storage and computing systems are facing growing challenges when inter-connecting across large wide-area network infrastructures. In particular, current technologies do not provide the desired automation and flexibility for end-system bandwidth delivery. This project will address this problem by developing advanced end-system control solutions, which combine off-the-shelf software with intellige ...

The data distribution and management functions for large-scale collaboration face significant challenges as emerging data-intensive applications necessitate efficient and secure transport across geographically dispersed locations. GridFTP is a powerful solution that has been developed to address these transport requirements for Grid computing, particularly within the Department of Energy. Consid ...

As network speeds increase beyond 10 Gb/s, software-based implementations of network functions are unable to keep pace. There exists the need for network interfaces that can be easily reconfigured at the hardware level to provide the user with any desired functionality, from real time intrusion detection to remote visualization. This project will develop a framework for an adaptable Network Inte ...

The U.S. Department of Energy has started a new Solar America Initiative (SAI) to accelerate the development of advanced photovoltaic (PV) systems. Significant technological advances have been made in the area of multi-junction solar cells for concentrated PV systems. Because these cells typically are suspended at the focal point of the reflecting mirror, the support structure must provide the b ...

Many industrial processes involve the transfer of heat from one medium to another. Thermal fluids and heat exchangers are often used as part of these processes. However, besides water or aqueous solutions, the other thermal fluids have thermal properties much lower than water, so larger heat exchangers or pumps are required. This project will develop a nanofluid with a nano-sized phase-change ...

A simple-to-use, microarray-based, environmental diagnostic device is needed to enable technicians and engineers to monitor the structure and dynamics of microbial communities in groundwater and subsurface environments. This project addresses this need by integrating complex molecular-microbiology operations into a fluidic architecture that can be mass produced at low cost and operated by any uns ...

America needs alternative energy sources to supplement or supplant traditional nonrenewable sources. Biomass, particularly wood waste, has become a desirable candidate; however, its high moisture content (as high as 50% by weight) and its difficulty in handling complicate the transport of wood waste. This project will develop technology for using biomass in the form of fuel pellets, processed at ...

The Oak Ridge National Laboratory (ORNL) has recognized that the generation of strong shock waves in the Spallation Neutron Source (SNS) can lead to cavitation and significant erosion on the vessel wall containing the liquid mercury target. Based on preliminary numerical and experimental work at ORNL and other laboratories, it has been proposed that a cloud of small gas bubbles in the mercury tar ...

It is not unusual to retrieve thousands or millions of results for a search query. Even though search engines try to rank search results by importance, the order of the results often does not reflect the interest of the person doing the search, and it is still necessary to browse through many pages of sparsely relevant information. When the results of several search engines are combined, as in m ...
