Scheduling a streaming application on high-performance computing (HPC) resources has to be sensitive to the computation and communication needs of each stage of the application dataflow graph to ensure QoS criteria such as latency and throughput. Since the grid has evolved out of traditional high-performance computing, the tools available for scheduling are more appropriate for batch-oriented a...

Visualization of data defined over large unstructured grids requires an efficient solution to the point location problem, since many visualization methods need values at arbitrary positions given in global coordinates. This paper presents a memory efficient, fast in-core solution to the problem using cell adjacency and a complete adaptive kd-tree based on the vertices. Since cell adjacency info...

Next-generation wireless networks should be able to coordinate and integrate different communication systems. It has been a challenging problem to support a seamless handover in these diverse wireless network environments. Link level triggers can provide information about events which can help handover decision and layer 3 entities better streamline their handover related activities. In most co...

Scalar and vector field visualization techniques have evolved almost independently. We think integration of scalar and vector visualization is still an interesting topic. For example, many researchers in fluid dynamics simulations still use 2D scalar and vector visualization techniques in one display, to demonstrate the coherency between scalar (e.g., temperature and air pressure) and vector (e...

Nowadays, B2B integration still remains a big cost driver for companies. On the one hand, standardization efforts were able to reduce the mapping effort between e-Business schemas. However, the effort for creating customized messages from the huge and underspecified standard templates increased. Due to the myriad of different requirements by different companies, a great variety of standards coe...

[1] We apply ‘‘residual mean’’ theory of tracer transport, in which eddy transfer plays a fundamental role, to develop scalings and idealized numerical models of the Southern Ocean uptake of transient tracers. The streamline-averaged numerical model, which represents transport in the meridional plane, captures the observed distributions of CFC-11, bomb-DC, and anthropogenic CO2. The model repro...

In recent years the print industry has been facing constant and increasing competition from the double onslaught of the Internet and the proliferation of television channels. In order to survive as a viable industry, print enterprises must streamline and exploit up-to-date economizing measures. A key cost element in the print industry is paper, representing between 20% and 30% of total printing...

Scientists are faced with increasingly larger volumes of data to analyze. To analyze and validate various hypotheses, they need to create insightful visual representations of both observed data and simulated processes. Often, insight comes from comparing multiple visualizations. But data exploration through visualization requires scientists to assemble complex workflows—pipelines consisting of ...

The analysis of data that consists of multiple vector fields can be greatly facilitated by the simultaneous visualization of the vector fields. An effective visualization must accurately reflect the key physical structures of the fields in a way that does not allow for an unintended bias toward one distribution. While there are several effective techniques to visualize a single vector field thr...

Integration of scalar and vector visualization has been an interesting topic. This paper presents a technique to appropriately select and display multiple streamlines while overlaying with isosurfaces, aiming an integrated scalar and vector field visualization. The technique visualizes a scalar field by multiple semitransparent isosurfaces, and a vector field by multiple streamlines, while the ...
