In this paper, a method for sensor placement to improve the placement quality based on angle of arrival of signal in a specific area is proposed. The installation place of sensors may be constrained with specified boundaries. In this me-thod, the criterion of maximum quality of placement is the Cramer-Rao bound. The generalized pattern search as an effective method is used to maximize error bound of the placement problem by angle of arrival. Better results are ob-tained in comparison with results of genetic algorithm. The derived results are compared from two aspects of run time and result quality.

In this paper, the problem of underwater passive target motion analysis (TMA) in three dimensions is discussed using the measurements of passive bearings and elevation and frequency on the condition that acoustic source and observer are in different horizontal planes. Simulation results with both of the PLE (pseudo-linear estimation) and MLE (Maximum likelihood estimation) show that the TMA method is effective in oceanic environment. Its error covariance curves tend to its Cramer-Rao lower bounds.

The effect of protein bound polysaccharide Krestin (PSK,a polysacchride extracted from Coriolus Versicolor)intraperitoneally injected into mice on the gene expression of SeGSHPx in peritoneal macrophages and of small dosage(1×10-6μmol/L) of tert-butyl hydroperoxide (tbOOH) in vitro on the gene expression of SeGSHPx in macrophage from mice treated by PSK were studied. The results showed that PSK could enhance the gene expression of SeGSHPx in macrophages,this corresponded with our previous work that PSK could increase the activity of SeGSHPx in macrophages. Small dosage of tbOOH had no marked effect on the gene expression of SeGSHPx in macrophages from mice treated by PSK,but could significantly induce the gene expression of SeGSHPx in macrophages from non-PSK treated mice.

Given a graph G, a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and ｜C｜ ≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as τC（G）, is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K（G）, is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F = {G｜ K（G） is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus τC（G）/｜G｜ ≤ 1/2 for all G ∈F.
