Due to advances in information technology, even Engineering Simulations can now be performed in web-based JAVA through an integrated operating system called Virtual Machine and the use of byte code, which guarantees the compatibility of identical codes in every computing system and makes it suitable for web-based simulation system development. This paper introduces an implementation embodied in JAVA Applet that allows a block-diagram type GUI that runs in a web browser for use in the dynamics simulation modeling of powertrains of vehicles and multi-body systems. This system is not restrained by any of the H/W and S/W in the user's computer, so that it has the advantage of providing a GUI that allows web-based block-diagram type modeling.

This paper presented a web-based virtual system to simulate forging operation. The system utilized simulation techniques of Finite Element Method (FEM) to analyze the forging process and Virtual Reality Modeling Language (VRML) to visualize the simulation results in the web. The analysis using FEM could show mechanical information such as stresses and deformation profiles of a specimen during forging process and the analysis results were transferred into virtual space using VRML. Since the forging machine and specimen were modeled using Java and VRML, the forging machine and analysis results were browsed and integrated on the web that is interfaced to users through EAI to show the whole forging simulation. The developed system realized the working environment virtually so that education and experiment could be performed effectively even on the PC.

A mathematical model describing the relationship between longitudinal tension and tangential velocity of web/roller in a multi-span web transport system has been developed. An experiment was carried out for typical conditions to validate the mathematical model for tension behavior in a multispan system. A two-span prototype prototype web transport system with winder and unwinder was manufactured for the experiment. By comparing simulation and experimental results, the mathematical model for tension and velocity in a multi-span web transport system is confirmed to be valid for typical conditions. Tension transfer phenomenon was also confirmed though the simulation as well as experimentation.

The use of the Web-based Simulation Environment (WBSE) provides a strong influence on supply chain simulations. A virtual supply chain simulation is available to evaluate strategies for reducing response time to customers and for shrinking the finished goods inventory along its supply chain. This paper presents the basic concepts and definitions of Web-Based Global Supply Chain Management (WBGSCM) simulation system. It also discusses the advantages of supply chain simulation modules integration. A Time Synchronization Mechanism (TSM) called Phased Bucket Scheme (PBS) is introduced as an approach of the distributed simulation modules integration.

The alignment of the rollers carrying the web is found to be one of important factors to the lateral behavior of the moving web and to the quality of the final web products. But, the perfect alignment of the rollers is not always possible and the web itself can be cambered. Thus the control of lateral behavior of the moving web is critical in the most of web handling systems. The web guiding system that adjusts the angle of the alignment between two adjacent rollers is commonly used in industry. But, in this paper a new web guiding system is proposed by using the lateral dynamics of the moving web induced by a tilted roller in normal direction of a web. The computer simulation study was carried out to verify the steering performance of the suggested guiding system. Computer simulation study shows that the performance of the new guiding mechanism is better than that of an existing guiding mechanism.

In this paper, we propose a new method for the design and implementation of Cloth Simulation System for 3D fashion shopping mall based on Web. Web 3D shopping mall is implemented by using a Web3D authoring tool, ISB, which provides easy mouse operation. 3D human models and cloth item model are designed by low polygon modeling method of 3D MAX. The designed 3D human models and cloth item model are exported to XML file. Finally, 3D human models and cloth item model are displayed and animated on the Web by using ActiveX control based on DirectX. We also implemented textile palette and mapped it to clothes model by using alpha blending during simulation.

We have developed an information management tool for the EDISON (EDucation-research Integration through Simulation On the Net) open platform. EDISON is, at present, a web-based simulation service for education and research in five computational areas, namely, nanophysics, fluid dynamics, chemistry, structural dynamics, and computer aided optimal design. The EDISON open platform consists of three tiers: EDISON application framework, EDISON middleware, and EDISON infra-resources. The platform provides web portals for education and research in areas such as computational fluid dynamics, computational chemistry, computational nanophysics, computational structural dynamics, and computer aided optimal design along with user service. The main purpose of this research is to test the behavior of the release version of the EDISON Open-Platform under normal operating conditions. This management tool has been implemented using the RESTful API designed in EDISON middleware. The intention is to check co-operation between the middleware and the infrastructure. Suggested tools include User management, Simulation and Job management, and Simulation software (i.e., solver) testing. Finally, it is considered meaningful to develop a management tool that is not supported in other web-based online simulation services.

The EDISON is a platform that supports numerical analysis for problem solving in computational science and engineering. We provide a cloud service for users, and provide an environment to access and execution of the simulation service on the web. For now, the EDISON platform provides simulation services for eight applied field on computational science engineering. Users can check the numerical analysis result by web in the computational science and engineering platform. In addition, various services such as community activity with other researchers, and the configuration of simulation environment by user 's needs can be provided. A representative service of the EDISON platform is a web-based simulation service that performs numerical analysis for problem solving of various computational science and engineering. Currently, EDISON platform provides workbench simulation service. It is the web-based simulation execution environment, and result analysis to provide simulation regardless of various personal computing resource or environment in each numerical analysis. In this paper, we build an interface for pre and post processor that can be used in conjunction with the workbench-based simulation service provided by EDISON platform. We provide a development environment with interface that is implemented by applying a pre and post processor optimized for the simulation service. According to simulation and execution are performed by linking the new workbench-based simulation service to the pre and post processor.

This study is analyzed by comparing the evaluation of usability and study achievement for simulation learning based on Web 3D and VR and it is aimed to verify the characteristics of the virtual reality through a difference in studying effect between each learning method. Therefore, this study is analyzed by comparing the evaluation of usability and study achievement for the CSI Forensics Lab simulation content that has been developed in two learning methods for scientific experiments of DNA analysis with the 75 university students of Life Science as a population(Web 3D=37, VR=38). The results of the study, in usability of user task action, exploratory and navigation, Web 3D simulation learning was positive in a significant difference, but in usability of satisfaction, VR simulation learning was positive in a significant difference. In study achievement, Web 3D simulation learning was slightly higher but did not confirm the significant differences between both of learning.
