Product family (PF) is the most important part of product platform. A new method is proposed to mine PF based on multi-space product data in PLM database. Product structure tree (PST) and bill of material (BOM) are used as the data source. A PF can be obtained by mining physics space, logic space and attribute space of product data. In this work, firstly, a PLM database is described, consisting of...
A new method for automated road extraction in remote sensing images is proposed based on Nonsubsampled Contourlet Transform (NSCT). Due to the advantages of multi-scale, multi-direction and translation invariance, NSCT is much efficient for the capture of linear singularity of road target. A pixel-wised feature extraction algorithm is given first based on the analysis of the NSCT coefficient responses...
In this paper, we present a supervised classification system for sorting Drosophila embryonic in situ hybridization (ISH) images according to their developmental stages. The proposed system first segments the embryo from an image and registers it for subsequent texture feature extraction. In order to extract the most distinguishing features for classifying developmental stages, we identify several...
A tape system is time-varying as tape winds from one reel to the other. The variations in reel radii consist of two components: the nominal reel radii change due to tape winding and the reel eccentricities as a result of non-circular reels. These variations introduce disturbances in the tape tension. This paper presents a feedforward control that addresses the time-varying reel radius to regulate...
Spreadsheet is one of the most commonly used end user programming environments. As such, there has been significant effort made by researchers and the industry to develop techniques and tools to improve spreadsheets. In the course of developing spreadsheet-based applications in Chinese governmental projects, we found that enabling end-user to program on the all-in-one, hard-to-validate Chinese spreadsheet...
When the development of an oil field comes into the middle and later stage, it is difficult to grasp the dynamic law due to continuous rising of water cut. A key to realize the optimal control of the whole process of oil development is to realize the accurate forecast of development indexes. This paper mainly investigates the application of data mining methods in development indexes forecast of an...
In recent years, Web plug-ins have been flourishing social networking sites. Web plug-in is successful since it results in unique user experience, and promotes the fast-pace innovation of Web technologies. However, the plug-ins developed by end users also introduces many new problems to both networking and software engineering fields. One of the key problems is pre-release failure. In other words,...
