Abstract Current resolvable group targets tracking algorithms can only track a small number of assuming the standard deviation vectors (SDVs) are known. Based on generalized labeled multi-Bernoulli filter, this paper first proposes serial algorithm, in order to save computational cost filter large-batch and multi-structure targets. Then, least squares k -means used jointly estimate SDVs target ...

topological indices are numerical parameters of a graph which characterize its topology. inthis paper the pi, szeged and zagreb group indices of the tetrameric 1,3–adamantane arecomputed.

in this paper, we  study the arens regularity properties of module actions. we investigate some properties of topological centers of module actions ${z}^ell_{b^{**}}(a^{**})$ and  ${z}^ell_{a^{**}}(b^{**})$ with some conclusions in group algebras.

An N2 resolvable latin squares is a latin square with no 2×2 subsquares that also has an orthogonal mate. In this paper we show that N2 resolvable latin squares exist for all orders n with n 6= 2, 4, 6, 8

In this article, necessary and sufficient conditions for the existence of a 1rotationally resolvable even-cycle system of kKv are given, which are eventually for the existence of a resolvable even-cycle system of kKv . # 2003 Wiley Periodicals, Inc.

The host and the guests were to be seated at three tables each of which had seven places. The di...

Abstract The m-order connectivity index mχ(G) of an organic molecule whose molecular graph is G is the sum of the weights (di1di2 · · · dim+1) 1 2 , where di1di2 · · · dim+1 runs over all paths of length m in G and di denotes the degree of vertex vi. Dendrimer is a polimer molecule with a distinctive structure that resembles the crown of a tree. Dendrimers are key molecules in nanotechnology an...

In this paper, uniform designs are constructed based on nearly U-type designs and the discrete discrepancy. The link between such uniform designs and resolvable packings and coverings in combinatorial design theory is developed. Through resolvable packings and coverings without identical parallel classes, many infinite classes of new uniform designs are then produced.
