We present RINGS, a technique for visualizing large trees with hundreds of thousands of nodes. We introduce a new ringed circular layout of nodes to make more efficient use of limited display space. RINGS provides the user with the means to specify areas of primary and secondary focus, and is able to show multiple foci without compromising understanding of the graph. The user can also control t...

An experimental investigation of a surface analysis method has been carried out. The method uses a scanned laser line to detect scratches on glass surfaces. The defects are detected as differences in the scattered light, which are recorded with a digital camera. A problem with this method is to distinguish between light from the back and from the front of the sample, since transparent samples a...

o began Mark Weiser’s seminal 1991 paper [1] that described his vision of ubiquitous computing, now also called pervasive computing. The essence of that vision was the creation of environments saturated with computing and communication capability, yet gracefully integrated with human users. When articulated, this was a vision too far ahead of its time — the hardware technology needed to achieve...

In precision machining processes, major problems can be related to the condition of the cutting tool. Online tool condition monitoring is hence of great industrial interest. To empower the machining system with adaptivity and intelligence required, an embedded tool condition monitoring system (eTCM) has been developed for online detection of machining process abnormities such as tool breaking, ...

In an interactive environment such as a visual language editor, it is not sufficient to apply the same layout algorithm in every situation. Instead, the user often wants to select the layout behavior at runtime. With the approach presented, the user can control the layout behavior by choosing different layout patterns for different parts of a diagram, e.g., a graph drawing algorithm may be appl...
