随着中国加入WTO,中国的银行面临的竞争越来越激烈。大型机技术与其它系统相比,在大规模数据处理上占有绝对优势。随着银行业务的扩大,银行联机事务量迅猛增加,业务与业务之间具有更加复杂的关系。CICS(Customer Information Control System)是IBM用于管理联机事务处理的最主要的处理平台,适用于有大量突发联机事件的系统。该文基于IBM大型机技术,分析归纳CICS的技术特点,对银行联机事务处理进行探讨。 相似文献
The paper presents a general approach to the evaluation of the complexity of classes of algorithms, so-called pVCD-method. To develop this method, all the examined families of models of empiric generalization were restricted to classes
implementable on computers and, wider, by examining their partially recursive representations. Within the framework of the
algorithmic approach, the concept of Kolmogorov’ complexity of algorithms for the recognition of properties or the extraction
of regularities is proposed. The method proposed to evaluate the nonrandomness of the extraction of empirical regularities
is based on this concept. 相似文献
Computer-aided analysis of autoradiographic films of DNA fragments is presented. The Powell least-squares procedure is used for optimization of parameters for components of complex densitometric curves. Since each densitometric spectrum may be divided for several non-overlapped blocks of bands, there is no upper limit on the number of parameters which must be optimized. Eight shapes for the component bands are utilized: symmetric and asymmetric Gauss and Cauchy functions, direct, symmetric and asymmetric product of Gauss function and inverse of Cauchy function, and log-normal function. The probability of DNA cleavage is calculated with correction for multiple cuts. The methods presented was applied to detailed analysis of densitometric spectra of a 21-bp DNA restriction fragment and allowed for direct correlation between structural microheterogeneity of DNA and the resulting cutting pattern. This method should facilitate the analysis of densitometric data from antibiotic-induced cleavage of DNA and footprinting experiments. 相似文献
In this paper, we study the semicycles of oscillatory solutions of the delay difference equation yn+1 − yn + pnyn-k = 0, where pn is a sequence of nonnegative real numbers and k is a positive integer. Upper bound of numbers of terms of semicycles are determined in the case when Our results improve and complement known results in literature. 相似文献
