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. Themost popular link-based technique, PageRank,uses a model of a random surfer to estimate theprobability that he visits a page at any giventime. This probability is assumed to beproportional to the relevance of the page.PageRank considers all ou...

By definition, an essential question of cyberlaw is to define when law will affect actions in cyberspace. Such law might be uniform, such as where nations have entered into a treaty or have adopted the same legal rule. Or, such law might be diverse, such as where nations adopt different legal rules. Diversity of law often does not matter for physical acts, such as where the criminal law of one ...

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 ...

Speech signals of the letter ‘zha’ (H) in Tamil language of 3 males and 3 females were coded using an improved version of Linear Predictive Coding (LPC). The sampling frequency was at 16 kHz and the bit rate was at 15450 bits per second, where the original bit rate was at 128000 bits per second with the help of wave surfer audio tool. The output LPC cepstrum is implemented in first order three ...
