The use of Virtual Environments in system control operation, in particular power systems (power generation and propagation), provides new paradigms to daily activities of monitoring and controlling. The existence of a three-dimensional geometric model, true to the real structures, when used to develop Virtual Reality systems, allows the acquisition of mental models that improve communication between...
Computerized systems employed for the analysis of cardiotocographic signals have become almost indispensable tools in fetal monitoring, for which evaluation of fetal heart rate signals plays a key role. Consequently to the diffusion of these systems, new software and complex signal processing methodologies are spreading and are gaining more and more interest. For testing the performances of new software...
How the brain maintains the stability of visual perception across saccade is a central question in systems neuroscience; accurately characterizing visual responses in the perisaccadic period is an important step towards understanding how the visual world is represented during saccades. Here, we develop a probabilistic model in the Generalized Linear Model framework to characterize and predict the...
Most of recommender systems build their predictions by analysing the preferences of users. However, there are many situations, such as in intelligent tutoring systems, where recommendations of pedagogical resources should rather be based on their memory. So as to infer in real time and with low involvement what has been memorized by users, we highlight in the paper the link between gaze features and...
In a building, the paint coating applied on interior walls presents an aesthetic roll and plays an important protective function. It is a building component exposed to degradation agents such as the use of housing, requiring a regular evaluation of its conservation status. The implemented model supports periodic inspections to the local and monitoring the maintenance of interior walls using Virtual...
More and more design and construction professionals in Architecture, Engineering, and Construction (AEC) areas have been and now are using Building Information Modeling (BIM). Unfortunately, there were very few efforts exploring the real-time communication and integration of BIM to the site and task conditions, and the interaction of BIM with the field crew. It is envisaged that Augmented Reality...
Given the new realities resulting from the territorial development of the network society, the article analyzes the relationship between Information and Communication Technologies (ICT) and planning. It seeks to essentially understand the impact of ICT on spatial planning, both as a working tool for professionals planning or as a vehicle for communication with the public and with public and private...
Over recent years the depth to which we have grown to rely on networked computer systems as part of the critical national infrastructure has become ever more apparent. Concern over difficulties caused by accidental failures has led to a realisation of the potential for damage that could be caused by targeted attacks and cyber warfare. Current approaches to addressing these problems have tended to...
To solve the gap between the theoretical teaching and practical training, some research on the structure of the bomber air turret, a lot of mission can be carried out such as device configuration, target selection, environment selection and so on. Flying sence simulation and the target simulation and shooting simulation are achieved. Also monitoring system stability and accuracy is enhanced. And a...
Large-scale data-intensive streaming applications in various science fields feature complex DAG-structured workflows comprised of distributed computing modules with intricate inter-module dependencies. Supporting such workflows in high-performance network environments and optimizing their throughput are crucial to collaborative scientific exploration and discovery. We formulate workflow mapping as...
Service Oriented Architecture (SOA) is a paradigm for organizing and utilizing distributed services as the basic construct to produce the desired results for service consumers. Large and complex computational units can be composed out of the available services. As the complexity and dynamism of the current global network systems grow significantly, the service architecture will also need to grow....
Collaboratively monitoring and analyzing large scale simulations from petascale computers is an important area of research and development within the scientific community. This paper addresses these issues when teams of colleagues from different research areas work together to help understand the complex data generated from these simulations. In particular, we address the issues when geographically...
Goods monitoring is an important item of video surveillance, which is necessary to run automatically in practice. Two incidents of goods monitoring including goods stolen and broken are considered in this paper. Following the process of video surveillance, a texture-based method is proposed to deal with the incidents. The main idea is to divide the image of each objective blocks into several regions...
This paper introduces an operational wellness model that forms the basis of a wellness visualization system. The operational wellness model is needed to determine a common reference enabling the evaluation of the visualization system. Existing definitions of wellness and wellness evaluation models have limitations and cannot be realized in software. The proposed model comprises the operational definition...
This paper presents a visualization analysis tool for detecting, analyzing and responding to the Distributed Denial of Service attack termed the Domain Name Service (DNS) amplification attack. The tool integrates agent technology, visual analytics and interactive visualization techniques to allow users to interact with the system in real-time, to monitor the network traffic, to analyze traffic information,...
Modeling cognitive performance using home monitoring data is a new approach to managing neurologic conditions and for monitoring the effects of cognitive exercise interventions. The data consists of activity monitoring from motion sensors and specific cognitive metrics embedded within our adaptive computer games. The frequency and continuity of data collection allows us to analyze within subject trends...
Virtual human can simulate many kinds of real human actions in virtual combat environment. An important characteristic of a virtual human is the ability to direct its perceptual attention to objects and locations in a virtual environment in a manner that looks believable and serves a functional purpose. We have developed a computational model of perceptual attention that mediates top-down and bottom-up...
During the study of abnormal capital flow, people can not access to a real financial transaction data as a result of many factors, therefore this article took the ways of intelligent agent role simulation, designed an agent decision-making model to verify the data collected. And from different perspectives the visualization of supervision to capital abnormal flow can be achieved.
In order to solve the problem of the current mine microseism monitoring, presents a method to use the OPENGL program language as the designing tool to establish the mine microseism monitoring 3D model. Based on the model, dynamic displays monitoring points and the microseism centre which is got by the monitoring data computing in the three-dimensional visualization system. It implements the purpose...
In the research prototypes of augmented reality (AR), the virtual rendering information always only relates to the external image features of real world. Due to this static and single-channel relation, AR technology could not dynamically show "virtual" augmented information according to the corresponding internal invisible state information of real objects. This paper presents a ubiquitous...
