This article describes X-NIndex, a novel approach for large XML documents with stable structure. The definition for the large XML document with stable struct ure is given while the concept of XML document tree coordinate(X-DTC) is introduced. The significant advantage of X-NIndex to other XML query schemas is shown and the experimental results are present.

This article is divided into two parts. In the first part, we prove some useful theorems on finite topological spaces. In the second part, in order to consider a family of neighborhoods to a point in a space, we extend the notion of finite topological space and define a new topological space, which we call formal topological space. We show the relation between formal topological space struct (F...

Post-focus compression (PFC), the lowering of fundamental frequency and intensity after focus, is previously found in English but not in Cantonese. This study examines the possible transfer of PFC between these two languages through bilingualism. It is found that out of ten bilingual EnglishCantonese speakers, eight have PFC in their English, but none has PFC in their Cantonese. This finding su...

For a nonsymm etri c threshold network equippe d with an asynchronous dynamics, we show that if the product of weights in any cycle of units is nonnegative, then each tr ajectory converges to a stable state with probability one. We also show that such networks have a natural feed-forward layer struc ture and stabilit y is achieved in a hierarchical order due to this struct ure. It follows then ...

This paper deals with stability problem for nonlinear delay systems. The proposed approach is based on the assumption that on a subset of instant states the system is represented by a continuous-time Takagi– Sugeno system with delay. The aim of the study is to present sufficient conditions of stability for the system subject to the constraints defining the subset under consideration. Because of...

In this paper, it is shown how a residual generator can be synthesized for time-delay systems using parity relations. The goal of this study is to investigate the application of a modern symbolic computation like MAPLE to the development and the design of fault detection systems for time-delay systems. In the literature, the problem brougth up by time-delay systems has been solved in two differ...

In this paper, the perturbed continuous-time large-scale system with time delays is represented by an equivalent Takagi-Sugeno type fuzzy model. First, two types of decentralized state feedback controllers are considered in this paper. Based on the Riccati-type inequality, the Razumikhin theorem, and the delay-dependent Lyapunov functional approach, some controller design approaches are propose...
