Given a dataset comprising a temporal sequence of communications between actors, how can we visualize the `flow' of communication over time? Current practice transforms the dataset into a dynamic graph - vertices represent the actors and directed edges represent the communications. The directed edges are added and removed over time. There are then several approaches to visualizing dynamic graphs that...
Elasticoluminescence (ESL) is a kind of mechanoluminescence (ML). ESL materials are novel functional materials that can convert elastic deformation energy into visible light directly. Utilizing the materials, novel sensing devices and various applications are now under development. These materials can allow direct viewing of stress distribution.
In order to discriminate normal and abnormal heart sounds (HSs) accurately and effectively, a new method for clinical diagnosis of the heart valve diseases is proposed. The method is composed of three stages. The first stage is the preprocessing stage. During the pre-processing stage, the improved wavelet threshold shrinkage denoising algorithm is used for the noise reduction of the measured HSs....

This paper designs and develops a game based on 3D forest scenes which gets a better balance between knowledge and gameplay. The game enhances...
According to the characteristics of GSM-R(Global System for Mobile Communications Railway), the Vehicular GSM-R Field Strength Testing System is required that the functions of receiving the data of GPS and displaying related geographic information that has processed and GSM-R field strength testing data situation on the electronic map. For these purposes, the implement program that geographic information...
This paper presents a simple color based segmentation technique for faces. The proposed technique utilizes saliency maps and incorporates both top-down (data driven) and bottom-up saliency methods to generate the saliency map used in the segmentation phase. The top-down approach uses skin color data obtained from a training database to bias the skin color saliency map while the bottom-up approach...
In order to reflect the actual deformation degree and trend of building structure and foundation pit, it was necessary to carry out the deformation measurement of subway construction and information management of construction monitoring. At the present moment, GIS had been applied in many fields but rare in analysis of deformation monitoring data. In this paper, GIS, with powerful capabilities of...
There is a wide range of applications in both military and civil fields for optimal path problem in raster terrain whose cost is visibility information. For the path search problem whose objective is maximal average horizon, the traditional algorithms are unsuitable due to the characteristic of the problem. This paper presents a method based on evolutionary algorithm, which may rapidly get the optimal...
A series of environmental and engineering problems, such as slope instability, mining water inrush, nuclear waste leakage and groundwater pollution may be related with the existence of a large number of fractures in the fractured rock masses. Accordingly, many large projects pertinent to mining, oil exploration, water protection, and hydropower engineering call for understanding the fracture networks...
This study focuses on customer relations management, and utilizes route optimization to achieve efficient delivery. It applies a service-directed architecture technology to allow clients, sellers, and logistics industries in the supply chain to communicate more closely. Through interactive online orders, consumers could conveniently monitor the status of their orders. In this era of energy deficiency,...
In order to solve the faults in usual detection of droplet distribution and motion in pesticide application and agricultural spraying field, a new method is given for the analysis of droplets characteristics and motion with PDIA (Particle/Droplet Image Analysis) and digital image processing technique. The diode laser is an illumination system that provides pulses of infrared laser light with variable...
The 3D terrain visualization of coastal zone is based on the seamless integration of geospatial data from water to land. Because of the differences in surveying methods and application areas, the land elevation data and the water-depth data are different in spatial reference, data accuracy and data type. This paper presents a methodology to integrate multisource terrain data of coastal zone and build...
Besides accelerating graphics rendering, GPU is also applied to high performance computing in non-graphics application field. For complex multivariate function on GPU, texture look-up method is proposed to enhance computational efficiency. Reconstruct the complex multivariate function to several two-variable functions and then map them to different 2D textures. When real-time running, one texture...
With shipping market fierce competition increasing, the traditional handling technology of bulk terminal yard can not meet the requirements of low-cost and high-efficiency. The 3D visualization technology is an important method to achieve the human-computer interaction, which can be used for improving handling efficiency and reducing operation cost of bulk terminal yard with the real time feedback...
In this paper, an efficient watermarking algorithm for color image is proposed based on HSI color space and Discrete Wavelet Transform (DWT). The color image is firstly converted from RGB to HSI format to obtain the intensity component. Then sub-blocks of intensity are divided and sorted according to the human visual system (HVS) characteristic. Finally, the scrambled binary watermark, which is achieved...

This article describes urban simulation, integrating some application of urban planning and management, summarizing some applied experience.
Online interaction was critical in underpinning the learning process in E-learning, and a framework for resource-oriented interactive learning, aiming to promote deep interaction among learners, resources and resource creators was proposed in this paper. Specifically, much research has been done to realize the interaction between learners and resources, recombination of resources and their presentation...
Segmentation is an important step in medical image analysis. This process is crucial but challenging due to inhomogeneneity in intensity of images. In addition, the images are often corrupted by noise and with contrast edges. There are some approaches aiming to cope with this kind of images such as: region growing, region competition, watershed segmentation, global thresholding, and active contour...
As Contourlet transform can give an asymptotic representation of edges and contours in image by virtue of its characteristics of multidirectional and flexible, it is introduced into the quality assessment of fused image. A new method (CSSIM) for image fusion quality assessment based on Contourlet and structural similarity of images is put forward in this paper. We introduce distortion channel to simulate...
