We present a geometric description, based on the affine Weyl group E (1) 6 , of two discrete analogues of the Painlevé VI equation, known as the asymmetric q-PV and asymmetric d-PIV. This approach allows us to describe in a unified way the evolution of the mapping along the independent variable and along...

The paper proposes the use of attack pattern ontology and formal framework for network traffic anomalies detection within a distributed multi-agent Intrusion Detection System architecture. Our framework assumes ontology-based attack definition and distributed processing scheme with exchange of communicates...

Disputes in construction projects are fairly common. They most often lead to increased costs, delays, and damaged business relationships. Disputes can also result in loss of reputation, personnel resources, and potential business opportunities. Previous studies have shown that the frequency of disputes...

The incremental updating of lower and upper approximations under the variation of information systems is an important issue in rough set theory.
