Ad-hoc networks and even more intrinsic pervasive networks face huge security lacks. In the most general case entities need to build up a well-defined security association without any pre-established secret or common security infrastructure. Under these circumstances it turns out that without unrealistic assumptions authentication of previously unknown parties is not achievable. However, for a ...

Common meadows are fields expanded with a total inverse function. Division by zero produces an additional value denoted with a that propagates through all operations of the meadow signature (this additional value can be interpreted as an error element). We provide a basis theorem for so-called common cancellation meadows of characteristic zero, that is, common meadows of characteristic zero tha...

In this paper, we consider a proximal point algorithm for finding a common zero of a finite family of maximal monotone operators in real Hilbert spaces. Also, we give a necessary and sufficient condition for the common zero set of finite operators to be nonempty, and by showing that in this case, this iterative sequence converges strongly to the metric projection of some point onto the set of c...

Using qualitative data gathered among correctional officers and a post-structuralist theoretical lens, this study suggests that emotion labor*/the instrumental use and suppression of emotion*/is more difficult when societal discourses and organizational processes limit employees’ ability to maintain preferred understandings of identity. The paper provides rich description of the complex web of ...

RÉSUMÉ. Dans cet article, nous présentons Gsharp, un projet dont le but est la création d’un éditeur de partitions de musique traditionnelles. Le logiciel Gsharp est écrit en Common Lisp et utilise CLIM (Common Lisp Interface Manager) comme bibliothèque pour l’interaction avec l’utilisateur. De nombreux algorithmes et structures de données ont été inventés afin d’assurer une performance accepta...
