This paper deals with the problem of searching for the best assignments of random variables to nodes in a Bayesian network (BN) with a given topology. Likelihood functions for the studied BNs are formulated, methods for their maximization are described and, finally, the results of a study concerning the reliability of revealing BNs’ roles are reported. The results of BN node assignments can be ...

The service provision problem described in this paper comes from an application of distributed processing in telecommunications networks. The objective is to maximize a service provider's proot from ooering computational based services to customers. The service provider has limited capacity of some resources and therefore must choose from a set of software applications those he would like to oo...

The node-searching problem, introduced by Kirousis and Papadimitriou, is equivalent to several important problems, such as the interval thickness problem, the path-width problem, the vertex separation problem, and so on. In this paper, we generalize the avenue concept, originally proposed for trees, to block graphs whereby we design an efficient algorithm for computing both the search numbers a...

This paper presents a practical heuristic algorithm to address a node discovery problem. The node discovery problem is to discover a clue on the person, who does not appear in the observed records, but is relevant functionally in affecting decision-making and behavior of an organization. We define two topological relevance of a node in a social network (global and local relevance). Association ...

simultaneous routing and resource allocation has been considered in wireless networks for its performance improvement. in this paper we propose a cross-layer optimization framework for worst-case queue length minimization in some type of fdma based wireless networks, in which the the data routing and the power allocation problem are jointly optimized with fuzzy distributed h∞ control strategy ....

Normal Dutch rabbit lymph node and spleen minces, lymph node cell suspensions, and residues from lymph node cell suspensions were cultured in Millipore chambers with slices of autologous or homologous (New Zealand) ear skin. for varying time intervals. Lymphoid cells exposed to New Zealand ear skin for more than 4 days were found capable of producing typical "transfer reactions" in the specific...

It is well-known that MAC protocols for multihop wireless networks face the problems of hidden and exposed nodes due to the limited transmission range of wireless nodes. The Distributed Coordination Function (DCF) mechanism of the IEEE 802.11 standard [2] addresses the issue of hidden node problem by employing a four-way handshake of RTS-CTSDATA-ACK frames. In this exchange, the transmitter emi...

the notion of strong arcs in a fuzzy graph was introduced bybhutani and rosenfeld in [1] and fuzzy end nodes in the subsequent paper[2] using the concept of strong arcs. in mordeson and yao [7], the notion of“degrees” for concepts fuzzified from graph theory were defined and studied.in this note, we discuss degrees for fuzzy end nodes and study further someproperties of fuzzy end nodes and fuzz...
