This paper presents a novel algorithm for Incremental and General Evaluation of continuous Reverse Nearest neighbor queries (IGERN, for short). The IGERN algorithm is general in that it is applicable for both continuous monochromatic and bichromatic reverse nearest neighbor queries. This problem is faced in a number of applications such as enhanced 911 services and in army strategic planning. A main...
The ultimate bearing capacity of single driven pile increases with time after pile installation, and it is of great importance to foundation design. Although various methods have been established to study this time-dependent ultimate bearing capacity of driven pile, they have different occasions for application, and the deduced results of them may differ greatly. In this paper, four typical types...
Ajax is an important approach for improving rich interactivity between Web server and end users during Web 2.0 eras. At the same time, the structured data in AJAX Web pages can not be extracted easily due to its asynchronous loading. In this paper, we propose a technique for extracting the structured data from the AJAX based Web pages. Firstly, an AjaxFetcher component is created to fetch the dynamic...
Extracting multi-records from web pages is useful, it allows us to integrate information from multiple sources to provide value-added services. Existing techniques still have some limitations because of their several restrictions and accuracy. This paper proposes a new method to perform multi-records extraction task automatically. Firstly, the HTML tag tree is build based on an embedded browser interface...
Mining the popular SMS messages in a short period of time is very valuable. However, traditional OLAP-based mining method is not suitable for this very large scale dataset. In this paper, we present a mining approach based on Map-Reduce parallel framework: Firstly, original dataset is pre-processed and grouped by the senders' mobile numbers. Secondly, we do a transformation to regroup the dataset...
