    Giant databases of 3D computer-aided design (CAD) parts might be the stuff of commercial design firms and manufacturers, but Karthik Ramani doesn't have to venture out of his Purdue University lab to see the need for a search engine that can sort through it all. Ramani and his colleagues have created a program, 3DESS (three-dimensional engineering shape-search system), that promises to make search... View full abstract»

    A powerful computational technique, large-eddy simulation, helps researchers study the detailed flow dynamics in the tip-gap region of hydraulic turbomachines. LES also helps researchers investigate ways to mitigate undesirable effects, such as cavitation, which can lead to reduced performance, increased noise, and structural vibration and erosion.

    Understanding the behavior of particles subjected to forces is a basic theme in physics. The simplest system is a set of particles confined to motion along a line, but even this type of system presents computational challenges. For the harmonic oscillator, a particle is subjected to a force directed toward the origin and proportional to the distance between the particle and the origin. The resulti... View full abstract»

    Smell (olfaction) can be critical to our daily living - for example, smelling smoke from a fire in time to leave a burning building - but it is seldom used in data visualizations or virtual reality (VR) systems. Could olfaction displays (devices that output scented air) augment data visualization, that is, communicate information relevant to many fields? Perhaps incorporating underutilized modalit...

    The Webgraph is the directed graph produced by the World Wide Web's hyperlinked structure: its nodes are static html pages, and its edges are the hyperlinks between two pages. Since the early '90s, the Web has grown exponentially - a trend we expect will continue. Today's Webgraph has several billion edges, but in spite of its size, it exhibits a well-defined structure characterized by several pro... View full abstract»
