We present a visualization framework integrated in a context-aware system that uses a common underlying stream processing middleware for tight integration of data accessing, processing, and visualization. Context-aware systems are often realized on mobile devices that do not have the computational power to perform complex tasks. Therefore, a dedicated hardware infrastructure might be required for...
The availability of low-cost virtual reality (VR) systems coupled with a growing population of researchers accustomed to newer interface styles makes this a ripe time to help domain science researchers cross the bridge to utilizing immersive interfaces. The logical next step is for scientists, engineers, doctors, etc. to incorporate immersive visualization into their exploration and analysis workflows...
Language differences pose significant barriers to multilingual communication. To understand others' conversation, a person should be conversant with the language in which the conversation is being carried out. It is difficult for an individual to join a conversation that is in a language unknown to him/her. Therefore, we have developed two conversation components visualization systems: an augmented-reality-based...
Information presentation desktop applications such as media players, digital signage players are heavily encountered by us in our daily life. However current presentation oriented desktop application architectures are not flexible and less efficient in presenting a variety of information. Desktop applications rely on embedded files and the contents they present are bound to presentation layout. This...
Digital Elevation Models (DEM) and 3D spatial data plays an important role in typical earth science applications. Broad needs for digital models of real environments such as 3D terrain or cyber cities are increasing. Many applications related to modeling and simulation requires virtual environments constructed from real-world geospatial information in order to guarantee relevance and accuracy in the...
OpenFlow protocol allows researchers to use programmable networking techniques to flexibly assign networking resources and manage network traffic according to user demands. In this paper, by taking SAGE Visualcasting as an example user application, we propose that OpenFlow-based programmable networking can be interactively utilized together with other monitoring schemes to enhance the performance...
Safety is a very critical domain in an industrial organization. This is especially true for organizations having multiplicity of scientific and engineering disciplines. This requires a broad based safety management system which has to take into account various aspects consisting of planning, management, preventive measures, compliance to safety standards and response to emergencies. In order to make...
Advanced visualization technologies are gaining major importance to interpret, present and manipulate high dimensional biomedical data. Since new health technologies are constantly increasing in complexity, adequate information processing is required for diagnostics, therapy planning and treatment. The combination of advanced visualization resources and biomedical grid infrastructures is a promising...
This paper presents an environment for molecular visualization with multi-projection and collaboration capabilities between geographically dispersed research groups. It was drafted a hardware and software architecture whose purpose is to reduce the negative effects of the delay in communication inherent long-distance networks.
Ultra high resolution image and gathering multiple images to tiled display improves effectiveness of scientific visualization application. In this paper, we introduce our applications of tiled display in detail. We investigated two kind of scientific visualization applications. The first is auto layout function that uses meta-information included into images. The second is high seed parallel volume...
The concept and technological composition of aircraft assembling process oriented assembly field is presented, its key technologies are explored respectively, the assembling process database is built based on Oracle system, the method and the procedure of assembling process simulation and optimization are formulated, and the visualization technology concerned with all kinds of assembling process information...
Diagnosing faults in an operational computer network is a frustrating, time-consuming exercise. Despite advances, automatic diagnostic tools are far from perfect: they occasionally miss the true culprit and are mostly only good at narrowing down the search to a few potential culprits. This uncertainty and the inability to extract useful sense from tool output renders most tools not usable to administrators...
Visualization of remote data needs software that is fundamentally designed for distributed processing and high-speed networks. Motivated by and following the requirements of a distributed visualization application, this article describes the design and implementation of a fast and configurable remote data access system called eavivdata. Because wide-area networks may have a high latency, the remote...
This paper explains some existing challenges for network topology visualization. An XML schema for network topology description is proposed to achieve the interoperability between different network management applications. For the better understanding of networks, we use XSLT stylesheet to visualize XML topology descriptions as Scalable Vector Graphics (SVG). It has also been explored how to embed...
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...
A proxy cache has quite a few difficult jobs to do. It is hard for people to effectively and efficiently do the maintenance work needless of mentioning the performance tuning work. In this paper we study the widely used proxy caching server--Squid. It suffers with well-designed tool to the management or evaluation of its performance or capability, which motivates us to design and implement friendly...
High performance computing (HPC) uses supercomputers to solve problems requiring complex computations that often produce large amounts pf data that must be analyzed interactively. We describe our work in this area on the Academic Leadership Pipeline Scholarship Computing and Analysis project consisting of two undergraduate student subprojects: MATLAB and ParaView visual analysis of jet engine fretting...
Botnets are emerging as the most significant threat facing online ecosystems and computing assets due to their enormous volume and sheer power. It is a major challenge for cyber-security research community to combat the emerging threat of botnets. Most of useful approaches for botnet traffic detection are based on passive network traffic monitoring and analysis. Nevertheless, typical network traffic...
Because of the importance effect of visualization in science computation, grid-based visualization has become a new research field, visualization application has visibility and high efficiency, which extends the range of service and the ability of remote access. Based on the campus grid platform, we integrate some multi-subjects parallel software, make a breakthrough on the techniques of web-based...
Industrial production continues to evolve. Rapidly changing processes require smaller batch sizes. The production locations are in this case often spread worldwide. At the same time, a constant access to process data is necessary in order to configure systems and to minimize downtimes. Remote service applications, like remote control and visualization as well as remote diagnostic and maintenance,...
