We consider the problem of design tools of knowledge bases in the environment of the Semantic Web. The dynamics of the development of software tools and design architecture are considered in the context of software technology in Semantic Web. There is given also a short description of the software platform for operation of Knowledge bases as Projects of virtual reality in Semantic Web.
In this paper we describe designing and implementation of a powerful, fast and compact simple 3D modeler (SM3D). In addition to saving cost and time (due to high processing speed), 3D objects can be created with minimum system resources by using this application. Easy learning and using are other strengths of this application. Modularity using classification and applying Dynamic-Link Library files...
Simulation remains one of the most popular and sometimes the only method of investigation of the complex dynamical systems nowadays. The problems become more and more complicate and so simulation models become complicate and large scale too. So the modelers have to reduce the time of simulation run and overall time of the simulation model design, it's verification, validation and simulation experiment...
Complex virtual environments (VEs) provide a multisensory, three-dimensional representation of real environments enabling their use in rehabilitation research to characterize and probe cognitive and motor abilities. This paper describes the application of a complex VE to characterize different motor and cognitive (executive) functions associated with navigating and shopping in an urban mall. The complex...
In this project, we tried to narrow down the gap between real world and synthetic environment. For that purpose, we developed an immersive driving car simulation that combines tangible tool with mixed reality environment. As tangible tool, we developed a real physical mini car that employ arduino sensor inside. To provide an immersive sensation among user and arduino mini car, we employ camera belongs...
For further study on the current models of electronic forensics, an electronic judicial identification model based on three-dimensional trusted electronic evidence acquisition model is proposed. The model implements linear process control, evidence supervision, time constraints and legal constraints and trusted fix of electronic data for the whole process of judicial identification. By establishing...
This paper presents a new virtual environment (VE) which employs a dynamic 3-D model of the classroom. It is based on powerful scientific visualization techniques and can be used as an effective aide in online virtual teaching. The learners enters the virtual model of the classroom as an avatar, navigate through it, zooms in or out as he or she wishes, changes his or her view point and perspective...
This paper presents selected issues connected with the design and implementation of the 6-DOF parallel manipulator driven by permanent magnet brushless DC motors. The consideration of platform kinematics structure, computer design and simulation of mechanical framework as well as building and utilization of the reduced-scale physical are presented. The development, implementation and testing of the...
We all agree with the fact that the reality is pretty good this will be experience by our sensory organs. Even the virtual world is amazing but the virtual and real world together working is complex. Gratefully this is changing now a days by new tool by which we can see our world with a layer of new information that's we called as Augmented reality (AR). Simply we can say that it's a combination of...
This paper proposes a 3D shape and color estimation method based on the photometric stereo method that uses images taken from multiple liner light sources. The proposed method can estimate partial object shape accurately. Hence we estimate multiple object shapes with different light source positions, extract partial object shapes and integrate them. An actual experimental situation is simulated and...
Reproducibility of experiments is the pillar of a rigorous scientific approach. However, simulation-based experiments often fail to meet this fundamental requirement. In this paper, we first revisit the definition of reproducibility in the context of simulation. Then, we give a comprehensive review of issues that make this highly desirable feature so difficult to obtain. Given that experimental (in-silico)...
Augmented reality is increasingly reaching young users such as elementary-school and high-school children, as their parents and teachers become aware of the technology and its potential for education. Although research has shown that AR systems have the potential to improve student learning, the educator community does not clearly understand the educational impact of AR, nor the factors which impact...
We present a Sketch-Based Interface that allows non-expert users to create an animation from just pencil and paper. The interface works as a fast mockup tool for creating animations - turning the user's freehand 2D sketches into 3D animations. To facilitate animation construction in offline or computer-scarce scenarios, special emphasis is placed on paper-based instead of tablet-based sketches. The...
Formal verification of variant requirements has gained much interest in the software product line (SPL) community. Feature diagrams are widely used to model product line variants. However, there is a lack of precisely defined formal notation for representing and verifying such models. This paper presents an approach to modeling and verifying SPL variant feature diagrams using first-order logic. It...
This paper introduces the problem of computing the shortest Euclidean path of a plural number of sequenced spherical balls in 3D. Based on the author's previous works and the technique of pair-wisely local optimization, a heuristic algorithm was proposed to solve the problem. Empirical results are competing with random selection and the nearest neighbor search algorithm. The experiments have shown...
The rapid growth of modern water conservancy technologies over the past decades has dramatically increased the amount of multi-dimensional data generated in water conservancy activities. A GIS system for the classification, retrieval, visualization and integration of water conservancy data are in their infancy. The advent of high performance computers with fast floating point and integer processors...
Aiming at the difficulty of large weapon equipment operation training simulation, GL Studio software tool was adopted based on VR technology. A hierarchy structure was put forward to simulate all kinds of integrating equipment system, single equipment and operation unit. Key technologies including Model database structure optimization, LOD, operation unit motion simulation based on DOF and screen...

During Computer drafting teaching, we present an easy three-dimensional simulation platform, on which 3D modeling and animation are illustrated. A simulation on natural scene is implemented through decomposable and order steps on the platform. Falling snowflakes, as an example, are simulated to show how a natural phenomenon is realized by using simple OpenGL functions, and water and swing are designed...
Application of virtual reality to tour guide training makes it possible to change the conventional teaching model into the communicative task-oriented one.
