Process of finding the right expert for a given problem in an organization is becoming feasible. Using web surfing data it is feasible to find advisor who is most likely possessing the desired piece of fine grained knowledge related with given query. Web surfing data is clustered into tasks by using Gaussian Dirichlet process mixture model. In order to mine micro aspects in each task a novel di...

There is questionable educational benefit in elementary/middle school in having learners surfing the Web without a clear task in mind. This is a report on the barriers and solutions encountered by three elementary/middle level teachers during their creation of two science WebQuests during the WebQuest/PDN Project, a joint university/school network venture in Maine. In the development phase, the...

The paper presents an interesting study that how the user surfing behavior with respect to the organization of a web space affects the performance of a prefetch enabled proxy. We have conducted experiments based on a novel hyperspace aware prefetch proxy and have studied the prefetch performance on several dominant hyperspace patterns including chain, tree, and complete graph sub-structures. Th...

This study investigated the effects of wave conditions on performance and the physiological responses of surfers. After institutional ethical approval 39 recreational surfers participated in 60 surfing sessions where performance and physiological response were measured using global positioning system (GPS) heart rate monitors. Using GPS, the percentage time spent in surfing activity categories ...

We propose a global convergence baud-spaced blind equalization method in this paper. This method is based on the application of both generalized pattern optimization and channel surfing reinitialization. The potentially used unimodal cost function relies on higherorder statistics, and its optimization is achieved using a pattern search algorithm. Since the convergence to the global minimum is n...

In general, all the keypad based authentication system having several possibilities of password guessing by means of shoulder movements. Shoulder-surfing is an attack on password authentication that has traditionally been hard to defeat. This problem has come up with a new solution. Devising a user authentication scheme based on personal identification numbers (PINs) that is both secure and pra...

A key question in brain development is how migration of neuronal precursors is guided to establish the ordered laminar layers. In the April 20, 2007 issue of Cell, Guan et al. show that the leading process of migrating cerebellar granule neurons senses repulsive Slit molecules by generating a Ca(2+) wave that propagates to the soma to cause reversal of cell polarity and migration.
