The aim of the minimization analysis of network attack graphs (NAGs) is to nd a minimum critical set of exploits so that by preventing them an intruder cannot reach his goal using any attack scenario. This problem is, ...

The Fuzzy Logic Congestion Detection (FLCD) algorithm is a recent proposal for congestion detection in IP networks which combines the good characteristics of both traditional Active Queue Management (AQM) algorithms and ...

Providing the stability of any rate allocation algorithm is a challenging issue in current high-speed networks. Some researchers, such as Kelly, Massouli e, Vinnicombe and Johari, have shown the stability of their ...

In this paper, the Conley index theory is used to examine the Poincar e index of an isolated invariant set. Some limiting conditions on a critical point of a planar vector eld are obtained to be an isolated invariant ...

Su cient conditions for the boundedness and regularity of a function, whose partial derivatives satisfy a certain set of equations, are presented. Energy methods are used to establish these results. The asymptotic behavior ...

Fractional-pixel accuracy Motion Estimation (ME) has been shown to result in higher quality reconstructed image sequences in hybrid video coding systems. However, the higher quality is achieved by notably increased Motion ...

The solvability of @ operator in a class of hypo-analytic manifolds in complex dimension 2 is studied. Suitable weighted L2 spaces are introduced for establishing an a priori inequality. The regularity of the solutions ...
