基于Web的应用程序构造模式比较研究

1 引言互联网改变了人们对信息的获取、传输、发布、共享、应用和可视化等的过程和方式,为应用程序数据提供者在WWW(World Wide Web)上给予了方便的信息发布与共享的方式。目前,几乎所有的管理信息系统都是建立在Web(或Internet)技术之上的,它们的构建属于分布式应用开发和大规模软件构架的范畴。其中,客户机和服务器是两个比较重要的概念。在客户机和服务器的配合下,信息的处理不仅仅是由某一方来完成,而需要多方的合作。由此可知,这种软件的构架完全不同于单机应用软件的构架。

A neural network model of a communication network with information servers

This paper models information flow in a communication network. The network consists of nodes that communicate with each other, and information servers that have a predominantly one-way communication to their customers. A neural network is used as a model for the communication network. The existence of multiple equilibria in the communication network is established. The network operator observes only one equilibrium, but if he knows the other equilibria, he can influence the free parameters, for example by providing extra bandwidth, so that the network settles in another equilibrium that is more profitable for the operator. The influence of several network parameters on the dynamics is studied both by simulation and by theoretical methods.The author was with the Intelligent Systems Unit, BT Laboratories, Martlesham Heath, Ipswich IP5 7RE, UK.     

On Pattern Frequency Occurrences in a Markovian Sequence

Consider a given pattern H and a random text T generated by a Markovian source. We study the frequency of pattern occurrences in a random text when overlapping copies of the pattern are counted separately. We present exact and asymptotic formulae for moments (including the variance), and probability of r pattern occurrences for three different regions of r , namely: (i) r=O(1) , (ii) central limit regime, and (iii) large deviations regime. In order to derive these results, we first construct certain language expressions that characterize pattern occurrences which are later translated into generating functions. We then use analytical methods to extract asymptotic behaviors of the pattern frequency from the generating functions. These findings are of particular interest to molecular biology problems (e.g., finding patterns with unexpectedly high or low frequencies, and gene recognition), information theory (e.g., second-order properties of the relative frequency), and pattern matching algorithms (e.g., q -gram algorithms).
