Distributed control system(DCS) has been used widely in industrial environments. This paper proposes new network system named ERCNet(Ethernet based Real-time Control Network), which satisfies all strict requirements of industrial environment like nuclear power plant. The proposed network, ERCNet uses ring topology, Token passing mechanism and physical media of Fast Ethernet. Proposed network ha...

Let T be a non empty FR-structure. We say that T is lower if and only if: (Def. 1) {−↑x : x ranges over elements of T} is a prebasis of T . Let us note that every non empty reflexive topological space-like FR-structure which is trivial is also lower. One can verify that there exists a top-lattice which is lower, trivial, complete, and strict. We now state the proposition (1) For every non empty...

BACKGROUND Understanding the complex hierarchical topology of functional brain networks is a key aspect of functional connectivity research. Such topics are obscured by the widespread use of sparse binary network models which are fundamentally different to the complete weighted networks derived from functional connectivity. NEW METHODS We introduce two techniques to probe the hierarchical com...

We present a novel framework to exert a topology control over a level set evolution. Level set methods offer several advantages over parametric active contours, in particular automated topological changes. In some applications, where some a priori knowledge of the target topology is available, topological changes may not be desirable. A method, based on the concept of simple point borrowed from...

We give a rigorous proof that for small positive values of the cosmological constant the Einstein equations coupled to an SU(2) Yang-Mills connection yield oscillating spacetimes. These are static, spherically symmetric spacetimes that have the same topology as particle-like spacetimes but differ in geometry. We also give a strict upper bound on values of the cosmological constant that admit su...
