This paper presents a zero tree coding method for color images that uses no lists during encoding and decoding,permitting the omission of the lists requirement in Said and Pearlman's Set Partitioning In Hierarchical Trees (SPIHT) algorithm . Without the lists, the memory requirement in a VLSI implementation is reduced significantly. This coding algorithm is also developed to reduce the circuit complexity of an implementation. Our experimental results show only a minor reduction of PSNR values when compared with the PSNR values obtained by th ....etc

Abstract”
The establishment of a Public Key Infrastructure (PKI) in Mobile Ad Hoc Networks (MANETs) is considered a difficult task because of the intrinsic characteristics of these networks. The absence of centralized services and the possible network partitions make traditional security solutions not straightforwardly applicable in MANETs. In this paper, we propose a publ ....etc

Abstract
Efficiency and scalability are fundamental issues concerning data mining in large databases. Although classification has been studied extensively, few of the known methods take serious consideration of efficient induction in large databases and the analysis of data at multiple abstraction levels. The paper addresses the efficiency and scalability issues by proposing a data classification method which integrates attribute oriented induction, relevance analysis, and the induction of decision trees. Such an integration leads to efficient ....etc

:heart:AN ALGORITHM FOR LABELING A TREE:heart:

KOH KHEE MENG AND TAY ENG GUAN

Abstract. An algorithm is described for labeling the vertices of a tree. A tree can then be determined by the collection of labels of its vertices, listed in lexicographic order.


1. Introduction

The notion of distance degree sequences of graphs was studied by Randic for the purpose of distinguishing chemical isomers by their graph structures. Other sequences for this purpose have also been proposed and discussed. The objective and hope is to deve ....etc

Definition
The concept of light tree is introduced in a wavelength routed optical network, which employs wavelength -division multiplexing (WDM).
Depending on the underlying physical topology networks can be classified into three generations:

a).First Generation: these networks do not employ fiber optic technology; instead they employ copper-based or microwave technology. E.g. Ethernet.
b).Second Generation: these networks use optical fibers for data transmission but switching is performed in electronic domain. E.g. FDDI.
c).Third Genera ....etc

Dynamic Balanced Key Tree Management for Secure Multicast Communications - IEEE TRANSACTIONS ON COMPUTERS, VOL. 56, NO. 5, – java

Abstract—
A secure multicast communication is important for applications such as pay-per-view and secure videoconferencing. A key
tree approach has been proposed by other authors to distribute the multicast group key in such a way that the rekeying cost scales with
the logarithm of the group size for a join or depart request. The efficiency of this key tree approach critically depends on whether the ....etc

ABSTRACT
The concept of a light-tree is introduced in a wavelength-routed optical network. A light-tree is a point-to-multipoint generalization of a lightpath. A lightpath is a point-to-point all-optical wavelength channel connecting a transmitter at a source node to a receiver at a destination node. Lightpath communication can significantly reduce the number of hops (or lightpaths) a packet has to traverse; and this reduction can, in turn, significantly improve the networkâ„¢s ....etc
