A quantity known as the Kemeny constant, which is used to measure the expected number of links that a surfer on the World Wide Web, located on a random web page, needs to follow before reaching his/her desired location, coincides with the more well known notion of the expected time to mixing, i.e., to reaching stationarity of an ergodic

Prefetching is a basic mechanism for faster data access and efficient computing. An important issue in prefetching is the tradeoff between the amount of network’s resources wasted by the prefetching and the gain of time. For instance, in the Web, browsers may download documents in advance while a Web surfer is surfing on the Web. Since the Web surfer follows the hyperlinks in an unpredictable w...

Standard techniques for estimatingweb page relevance neglect the informationprovided by the visual layout of the page.

Abstract. Water flowing in the river causes a scouring event that occurs at bed channel. The existence of will increase along with changes geometry and obstacles such as weir which are followed by local around weir. Local often downstream end sill weakens its construction. Scouring measurement was conducted to monitor pattern occurs. By using Surfer software, visualization through Data Grid 3D ...
