XML documents have both structural and semantic information, bringing data integration and deep utilization based on XML more precise description and versatile expression. But in the meanwhile traditional NLP and DM methods can't be applied directly. Feature dimension reduction and general similarity of XML based on tensor analysis are discussed. Considering the correlation between XML's structure...
Facing tremendous volume of semi-structured XML and non-structured free text, network information retrieval is one of the most research hotspots in dealing with these data more efficiently, precisely and uniformly. Many traditional IR methods ignore text semantics and their labeling result has usually only one level, lacking of context expression as well, therefore structure extraction from free text...
In a wireless sensor network (WSN) platform, there are always many different applications. These applications usually have different quality of service (QoS) requirements. However, in most situations, these different requirements cannot be satisfied simultaneously in the same platform. In this paper, based on the concept of potential in physics, we propose DRRP, a routing algorithm with the ability...
Water quality assessment and prediction of Lake Michigan are becoming major challenges in Northwest Indiana. Traditionally, mechanistic simulation models are employed for water quality modeling and prediction. However, given the complicate nature of Lake Michigan in Northwestern Indiana, the detailed simulation model is extremely simple in comparison and, at some point, additional detail exceeds our...
An effective XML cluster method called neighbor center clustering algorithm (NCC) is presented in this paper, whose similarity is obtained through both structural and content information contained in XML files. Structural similarity is measured by the idea of Longest Common Subsequence, while content similarity is achieved using TF-IDF principles. It reduces computation complexity by avoiding direct...
Generally, when an earthquake occurs, rescue operations cannot be effectively conducted timely due to the interruption of communications. This paper proposes a novel communication approach, wireless mesh network (WMN) communication, which can provide network access for emergency rescue services after the earthquake to satisfy the communication requirements of rescue work. Simultaneously, when the...
With the deep prevalence of the wireless network and sensor technology, the real time monitoring system with some application environment comes true gradually. This article designs a feasible intelligent home-hospital system (IHHS) to a certain extent through the pivotal context-aware technology which plays an important role in the area of the pervasive computing and the wireless sensor network (WSN)...
Maintaining consistency constraints in a complicated development environment is ever an open problem, as different development tools are usually involved which in turn use various files or databases to store their data. To solve this problem, current XML technology was used to build a repository which manages all data of a development effort. XML queries were also presented to state consistency constraints...
Silicon carbon nitride thin films were prepared by microwave ECR plasma enhanced unbalanced magnetron sputtering. Chemical structure, mechanical and optical properties of the films as a function of graphite target voltage has been studied. The chemical structure in the deposited film is investigated with Fourier transform infrared spectroscopy (FTIR). The Si–C–N bonds increased from 17.14% to 23.56%...
