Since the late 1990s, studies of team performance management have experienced a great growth over a decade. Researchers study on this field from several different aspects and subjects. Reviewing these years' hot domains and research trends of team performance management, it's clear that the study from the very beginning have a comprehensive, intercrossing and complicated feature. Taking use of co-citation...
The more application of visualization techniques in medicine, geology and other fields is employed, but less use in structural damage detection area. This paper presents visualization of damaged rail, in which the damage has been identified via wavelet transform. First, a simulation of intact and single damages rail was carried out. Then, the displacement modes of intact and damaged rail are extracted...
There is an emerging focus on real-time data stream analysis on mobile devices. A wide range of data stream processing applications are targeted to run on mobile handheld devices with limited computational capabilities such as patient monitoring, driver monitoring, providing real-time analysis and visualization for emergency and disaster management, real-time optimization for courier pick-up and delivery...
Free viewpoint video enables the visualisation of a scene from arbitrary viewpoints and directions. However, this flexibility in video rendering provides a challenge in 3D media for achieving spatial synchronicity between the audio and video objects. When the viewpoint is changed, its effect on the perceived audio scene should be considered to avoid mismatches in the perceived positions of audiovisual...
Summary form only given. This talk gives an overview of an effort on deploying news event extraction technology for border security intelligence gathering and real-time situation monitoring for Frontex, the European Agency for the Management of Operational Cooperation at the External Borders of the Member Stated of the European Union. In particular, a hybrid multilingual event extraction system has...
Researched and developed the software system of Information Management and Decision Support System of the hidden danger troubleshooting of Coal Mine. By using the technology of collaborative software to realize fast circulation of information, dynamic tracking, rapid feedback, and closed-loop management of transaction processing for the hidden danger, and by applying the technology of data mining,...
Nowadays, online social networks host more and more applications in order to provide their users with the possibility of finding everything they need on a single platform. The number and diversity of interactions that take place over time between users and applications within these platforms make these environments very good candidates for learning various types of information about users' interests...
In this paper, we used X-Means clustering algorithm, incorporated data images from a so-called Iterative Data Image Rotated Bar Graph (iDIRBrG) method (formerly referred as BC method) and used Vector Fusion Visualization to achieve better traffic data analysis results compared to our previous work by improving how data signatures are constructed from the raw data set. By doing so, we effectively identify...
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....
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...
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...
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...
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...
This paper presents an innovative procedure, capable to automatically generate virtual environments which are applicable to art galleries, museums or similar facilities, and suitable for web-based promotions of artists and their works. The presented system is part of the outcome of an interdisciplinary research for low-cost and platform independent solutions to combine art with virtual reality with...
Visualization has been around for more than two decades. Various techniques have been proposed, and some have found their fitting places in many applications in documentation visualization, scientific visualization, etc. To our knowledge, no one has applied the Weibull distribution's probability density functions whose flexibility lies in their adjustable shape and scale parameters to the information...
In off-road simulation, the terrain is being modified as a result of its interaction with the vehicles. Previous methods just deal with relatively small scale terrain inputs. In this paper we describe a large scale dynamic terrain visualization method. The potentially visible portion of the terrain is cached in the form of texture arrays and is rendered from the GPU. The terrain deformation is generated...
The networking construction and management is the core technology in computer networking designs. And the main purpose of computer networking courses is also to develop students' practical abilities of networking construction and management. Currently computer networking designs become more practical and the networking construction and management techniques are also more abstract and virtual, which...
In computation flow visualization, integration based geometric flow visualization is often used to explore the flow field structure. A typical time-varying dataset from a Computational Fluid Dynamics (CFD) simulation can easily require hundreds of gigabytes to even terabytes of storage space, which creates challenges for the consequent data-analysis tasks. This paper presents a new technique for path-lines...
In this paper, based on the in-depth research of existing 3D modeling algorithms, a new graphical 3D modeling visualization algorithm is proposed. This algorithm can use relatively smaller images demand to generate 3D model with higher precision, thus the efficiency of the 3D modeling realization will be greatly improved. Moreover, this algorithm is simple to achieve, easy to operate, and therefore...
