Eye tracking has commonly been used to analyse user behaviours on the Web [2]. When users navigate on web pages, they make a series of fixations. In other words, their eyes become relatively stationary at certain points. These series define their scanpaths on the pages. Figure 1 illustrates an example of a user scanpath on the Godaddy page that is segmented into its visual elements such as menu...

Concept drift refers to the phenomenon that concepts change their intensional composition, and therefore meaning, over time. It is a manifestation of content dynamics, and an important problem with regard to access and scalability in the Web of Data. Such drifts go back to contextual influences due to social embedding as suggested by e.g. topic analysis, news detection, and trends in social net...

We present a de-trending algorithm for the removal of trends in time series. Trends in time series could be caused by various systematic and random noise sources such as cloud passages, changes of airmass, telescope vibration or CCD noise. Those trends undermine the intrinsic signals of stars and should be removed. We determine the trends from subsets of stars that are highly correlated among t...

Three pulse contour systems for monitoring cardiac output - LiDCO Plus™, PiCCO Plus™ and FloTrac™ - were compared in postcardiac surgery patients. None of the three methods demonstrated good trending ability according to concordance analysis. Pulse contour systems remain unreliable in the haemodynamically unstable patient.
