To analyze point cloud data of a car part, massive computations need to be carried out; if it is done by conventional ways, the processing efficiency is relatively low. However, by applying partition method to point data analysis, the work is easier. Such partition method should follow the minimal-distance matching principle to find out the enclosing matching points. Then the intersections of the...
It is important to fabricate bio-mimetic artificial bone (BMAB) with the similar structure and properties as human bones. An innovative concept for manufacturing the custom-tailored BMAB has been proposed, which is achieved by layer slurry gelation. The bone scaffolds with complex and delicate structure are produced using the computer-controlled three-dimensional (3D) rapid prototyping (RP) system...
Near infrared (NIR) absorption spectroscopy is a promising technique to noninvasively quantify blood glucose level. In order to extract the glucose signal out of the noisy background, Partial Least Squares (PLS) was utilized to create calibration models that relate the absorption spectra to glucose concentrations. A research grade Fourier Transformed Infrared (FTIR) spectrometer configured with a...
Ploarimetric Synthetic Aperture Radar (POLSAR) provide more information of targets, advantages of which lays in its capability to acquire useful images with any-weather conditions and at night time. POLSAR image has been used to reconnaissance Ships and vessels. Specifically, this paper proposes an improved notch detector algorithm of ship with full polarimetric image. The methodology adopted the...
In order to establish the spatial data model for mines, the mine spatial environment was analyzed, five characteristics of spatial phenomena in mines and five demands for the 3D spatial data model of the mine basic information platform were summarized. Then an entity-oriented spatial-temporal data model with parameter skeleton was designed. It integrates the topology-concerned vector data model and...
The incentive mechanisms based on reputation are often used to induce cooperation among selfish nodes to route and forward packets in ad hoc networks. Those mechanisms propose that nodes with lower reputation value will receive less benefit. This class of schemes suffers from a new problem of second-ordered free riding. Refusing service request from nodes with low reputation will increase the defector's...
The mining programming of accumulated bauxite should comprehensively consider the site selection and rational utilization of resources. The mixed integer programming model on optimization of site selection and rational ore blending was constructed on the basis of the theories of logistics planning, operations research, etc. Take Taipingbei mine in Pingguo bauxite as the example, the results which...
Web services have become the prominent standards for distributed application. Extending from software component, web component is a new paradigm to support service-oriented software development and reuse in web environment. Web component aims at providing support to service-oriented development by enabling automatic discovery, composition, invocation and interoperation of services. Semantic support...
Semantic Web service makes service representation and discovery more machine-understandable by adopting ontology semantics. However these representations are inadequate to descript and discover services imprecisely requested by human. Fuzzy ontology is an extension of the domain ontology. It is more suitable to describe the domain knowledge for uncertainty representation and reasoning. In this paper,...
