Poor website usability has been identified as one of the main reasons why users abandon potential transactions. Appropriate evaluation of these sites is therefore essential. A problem with usability and UX evaluation is the lack of trust des...

We introduce a framework for an empirical evaluation of probabilistic logic languages and systems.

In this evaluation the efficiency of three image signature called angular spectrum, Hough based signature and color histogram are tested The first signature is intrinsic hierarchical (deriving from image frequency spectrum) and than non signature space reduction technique is used. The second is a short signature directly indexed and the last (color histogram) need to be reduced for fast indexin...

These therapies not only harmed patients but also did a disservice to the practical education of medical students, residents, and fellows. These trainees effecti...
