Currently, by default, integral curves are repeatedly re-computed in different flow visualization applications, such as FTLE field computation, source-destination queries, etc., leading to unnecessary resource cost. We present a compression-based data reuse framework for integral curves, to greatly reduce their retrieval cost, especially in a resource-limited environment. In our design, a hierarchical...
The development of supercomputers has greatly help us to carry on large-scale computing for dealing with various problems through simulating and analyzing them. Visualization is an indispensable tool to understand the properties of the data from supercomputers. Especially, interactive visualization can help us to analyze data from various viewpoints and even to find out some local small but important...
Recently, ubiquitous computing has been garnering a great deal of attention. In ubiquitous computing environments, sensor nodes connected to a network are used for collecting sensor data. However, considering the cost needed to set up the network, it may be more convenient to use data loggers that directly send data to users than to use a sensor network. In this paper, we propose a ubiquitous data...
