Existing desktop search applications, trying to keep up with the rapidly increasing storage capacities of our hard disks, offer an incomplete solution for information retrieval. In this paper we describe our Beagle desktop search prototype, which enhances conventional fulltext search with semantics and ranking modules. This prototype extracts and stores activity-based metadata explicitly as RDF...

With increasing storage capacities on current PCs, searching the World Wide Web has ironically become more efficient than searching one’s own personal computer. The recently introduced desktop search engines are a first step towards coping with this problem, but not yet a satisfying solution. The reason for that is that desktop search is actually quite different from its web counterpart. Docume...

With the development of IT technologies, the amount of information that the user receives and the sources of information which he or she uses, increased dramatically. There is a need of an intelligent desktop application, which will integrate different information sources from both the desktop and the web. To address this problem, we present a solution for a semantic desktop application, which ...

To reduce energy wastage by idle desktop computers in enterprise environments, the typical approach is to put a computer to sleep during long idle periods (e.g., overnight), with a proxy employed to reduce user disruption by maintaining the computer’s network presence at some minimal level. However, the Achilles heel of the proxy-based approach is the inherent trade-off between the functionalit...

1. MOTIVATION Sophisticated web search technology usually allows us to find appropriate documents in a few seconds. Finding these documents on our desktop is surprisingly more difficult, at least if we have been storing documents for a few years or more. This is improving somewhat with the recent crop of desktop search engines, but even with these tools, searching through our (relatively small ...

dry eye is the major contributor to computer vision syndrome. the reductions in the blink rate and amplitude have been considered as the possible mechanisms leading to this condition. the purpose of this study is to evaluate the changes in the lower tear meniscus heights and areas in the computer reading task, in dry eye subjects, with and without soft contact lenses. in this quasi-experimental...

We describe visualization software, Visualizer, that was developed specifically for interactive, visual exploration in immersive virtual reality (VR) environments. Visualizer uses carefully optimized algorithms and data structures to support the high frame rates required for immersion and the real-time feedback required for interactivity. As an application developed for VR from the ground up, V...
