Websites usually appear to the web surfer like isolated islands: Their self-description and their hyperlinks linking to other sites reflect solely the requirements, opinion and preferences of the respective site owner, there is no explicit relation to the information, service and product offers of competing sites, and the assessment of the site by other users is unknown as well. In contrast to ...

In this paper, we first extend the celebrated PageRank modification to a higher-order Markov chain. Although this system has attractive theoretical properties, it is computationally intractable for many interesting problems. We next study a computationally tractable approximation to the higher-order PageRank vector that involves a system of polynomial equations called multilinear PageRank. This...

Intrusions are often viewed as catastrophic events which destroy systems, wreak havoc on data through corruption or substitution, yield access to closely guarded sensitive information, or provide a springboard for hackers to attack other systems. Yet not all intrusions on the Web are the blatant, smash-and-grab, trash-the-site kind of attacks. Many attacks are more subtle, and some involve what...

conclusions according to the factory noise map, except for the control rooms with 81 dba noise, other cases of measuring stations were higher than the standard exposure of 85 dba noise. as a result, the implementation of control strategies, such as inspection and performance of control systems and insulation of the control room to prevent unnecessary exposure noise, are necessary. background st...

This paper deals with the methodology of modelling the Dubňany lignite seam base and its tectonic failure. Tectonic pattern of the Vienna Basin has been subject of many studies. Opinions on its origin have been developing. Coal seams in the South Moravian Lignite Coalfield were modelled under the project of the example modern evaluation of the coal deposit. Designed software with application of...

The increasing number of uncharacterized protein structures necessitates the development of computational approaches for function annotation using the protein tertiary structures. Protein structure database search is the basis of any structure-based functional elucidation of proteins. 3D-SURFER is a web platform for real-time protein surface comparison of a given protein structure against the e...

Early approaches to mathematically abstracting websurfing behavior were largely based on first-order Markov models. Most humans however do not surf in a “memoryless” fashion, rather they are guided by their timedependent situational context and associated information needs. This belief is corroborated by the non-exponential revisit times observed in many site-centric weblogs. In this paper, we ...
