An Intelligent Decision Support System Generator

The focus of this paper is on a new concept framework and an architecture of an intelligent decision support syetem generator (DSSG). The framework results from a synthesis of two existing frameworks: Spragae and Bonczek, while the architecture is a rooted partial order network. From our experience which comes out of the project of DSSG, we consider that they are keys of further research and development of DSS.     

低钴易磨削超硬高速钢Co3N系列

Co对易磨削(1％V)的超硬型W-Wo和Mo系高速钢性能影响的研究表明,随Co含量的提高,二次硬度上升,3％-5％Co还可提高钢的强韧性,8％Co则有明显的脆化作用。新的低Co超硬高速钢Co3N在硬度、红硬性、强度、韧性和可磨削性诸方面皆达到M42的水平。     

K连通图的k分割多项式算法

图G的K分割问题可描述为:输入(Ⅰ)G=(V,E),G为简单无向图,其中|V|=n,|E|= m;(Ⅱ)a_1,a_2,…,a_k k个G中不同的顶点;(Ⅲ)n_1,n_2,…,n_k k个正整数满足 n_1+n_2+…,+n_k= n.输出(V_1,V_2,…,V_k),对1≤i≤k,满足(Ⅰ)a_i∈V_i;(Ⅱ)G[V_i]是连通图;(Ⅲ)|V_i|=n_i.本文给出时间复杂性为O(knm)通用K连通图的k分割多项式算法.     

静脉注射免疫丙种球蛋白柱层析分离的研究

用凝胶渗透谱色法(GPC)检测了柱层析分离纯化后所得的免疫丙种球蛋白(IgG)组分.结果表明,使用DEAE 阴离子交换纤维素-葡聚糖凝胶A-50柱层析法能从人血浆蛋白中分离出不含聚集体的纯IgG 单体.对肌注IgG 制剂使用葡聚糖凝胶Sephacryl S-200凝胶过滤法能除去IgG 中的聚集体,但却不能分离出存在于其中的小量血清白蛋白;但使用DEAE阴离子交换纤维素柱层析法效果却恰好相反.

THE CHARACTERISTIC PAIR AND TRACE EXPRESSION OF LR ARRAYS

In this paper, the concept of characteristic pair of linear recurring (or LR inshort) arrays is introduced. A decomposition of the linear space consisting of LR arraysand trace expressions of LR arrays is showed.     

Distributed Parameter Neural Networks via Adaptive Wavelet

The paper outlines a new neural net (DPNN) for describing brain's action based on one-dimensional cable theory. While the traditional neural network system only finding its character involving time changing (as HNN, BP etc.), the model-DPNNs (distributed parameter neural networks) are not only the transmitted neurons of time variation, but also the functions of positions by the voltage u(x. I). With the neuroscientific relevance, some bionural features like intermittent conduction and dendritic spike are fixed well by DPNNs which considered as complicated and adaptive devices contract to the functional elementary units. To find the semi-analytical representation of DPNNs, adaptive wavelets are utilized as new microlocalization tools. While maintaining all advantages of wavelet function, the adaptive wavelet offers a viable alternative learning procedure to the orthogonal least squares method (OLS), Adaptive wavelet method develops a fairly general, low-cost multiscale method for neural net optimization.
