The Next Steps In Signalling (NSIS) protocol suite represents an extensible framework for enabling various signalling applications over IP-based networks. The framework consists of two layers that need different types of security protection; the lower layer mainly deals with the discovery of adjacent peers and establishment of channel security to protect the delivery of signalling messages betw...

Addressing scheduling problems with the best graph coloring algorithm has always been very challenging. However, university timetable problem can be formulated as a where courses are represented vertices and presence of common students or teachers corresponding edges. After that, stands to color lowest possible colors. In order accomplish this task, paper presents comparative study use in sched...

Macro-elements of arbitrary smoothness are constructed on Powell-Sabin triangle splits. These elements are useful for solving boundaryvalue problems and for interpolation of Hermite data. It is shown that they are optimal with respect to spline degree, and we believe they are also optimal with respect to the number of degrees of freedom. The construction provides local bases for certain supersp...
