This paper describes a Virtual Reality (VR) based environment for conceptual design that allows the generation of an entire plant design along with an accurate cost estimate. The use of visualization coupled with advanced design and optimization methodologies help to rapidly investigate competing plant designs. The software is composed of two modules; the Optimization Engine or Optimizer and the Graphical User Interface (GUI) or Visualizer. The Optimizer comes up with various layouts (designs) along with a cost estimate, which the Visualizer uses to give a 3-D model of the plant. The Visualizer operate in three different modes; (1) Virtual Reality mode with advanced interface to visualize on a CAVE type large display systems, (2) Web viewer designed to be used in conjunction with a distributed design environment and (3) a PC desktop mode for quick design review with additional functionalities over a Web based system. To allow a seamless integration between the Optimizer and the Visualizer an efficient XML based data transfer has been developed. XML provides a robust, non-proprietary, persistent and verifiable file format for the storage and transmission of text and data. As XML data is to be manipulated from within a programming language, the Xerces XML parser, written in a portable subset of C++, has been used.

This paper presents a web-based software for designing optimal central utility plants. This tool can receive user-defined load profiles or generate typical load profiles based on user-specified combination and areas of 16 reference building types. The software then solves a linear-programming optimization comprising 8760 sets of equations and constraints to design central plant configurations with minimal first cost, operating cost, life-cycle cost, energy use, or marginal carbon emissions. The tool also calculates simultaneous heating and cooling loads to evaluate using heat-recovery chillers, and it can design both hot and cold thermal energy storage as well as water-side economizers.

Shared Virtual Environments

AbstractRecent advances in the field of web technologies, including the increasing support of virtual reality hardware, have allowed for shared virtual environments, reachable by just entering a URL in a browser. One contemporary solution that provides such a shared virtual reality is LIRKIS Global Collaborative Virtual Environments (LIRKIS G-CVE). It is a web-based software system, built on top of the A-Frame and Networked-Aframe frameworks. This paper describes LIRKIS G-CVE and introduces its two original components. The first one is the Smart-Client Interface, which turns smart devices, such as smartphones and tablets, into input devices. The advantage of this component over the standard way of user input is demonstrated by a series of experiments. The second component is the Enhanced Client Access layer, which provides access to positions and orientations of clients that share a virtual environment. The layer also stores a history of connected clients and provides limited control over the clients. The paper also outlines an ongoing experiment aimed at an evaluation of LIRKIS G-CVE in the area of virtual prototype testing.

Abstract Virtual reality is a technology which is often regarded as a natural extension to 3D computer graphics with advanced input and output devices. This technology has only recently matured enough to warrant serious engineering applications. The integration of this new technology with software systems for engineering, design and manufacturing will provide a new boost to the field of computer-aided engineering. One aspect of design and manufacturing which may be significantly affected by virtual reality is design for assembly. This paper presents the ideas behind a current research effort aimed at creating a virtual assembly design environment and integrating that environment with a commercial, parametric CAD system.

Time Restriction

The modern web-based distance education overcomes space-time restriction of the traditional teaching forms. However, being short of specifically observable and operable experimental equipment makes the web-based education lack advantages in the knowledge learning progress, which needs strong stereoscopic effect and operability. Truck crane is the most widely used crane installed on ordinary or tailor-made chassis with strong operability. This paper introduces a kind of interactive truck crane simulation platform based on the virtual reality technology, on which can complete the simulation experiment of the crane's movement. The framework and working principle of the interactive truck crane simulation platform are discussed in the paper, while landing leg and hook are used as an example to show the motion control mechanism of truck crane components. The interactive truck crane simulation platform uses the browser-based structure, Java3D, virtual reality and Java Applet, etc. to develop a Web3D virtual reality learning environment, which has the advantages of good interaction, strong sense of reality, simple update, less investment and so on. This learning environment can meet the needs that many students study online at the same time, so it has important application in the distance education of mechanical profession and remote training of vocational skills.

This research aims to determine the results of the development of web-based learning media for Islamic Religious Education (PAI) which is valid and practical. This learning media development model refers to the 4-D development model (Four D-Model). This research was conducted at Unismuh Makassar Junior High School with research subjects 30 students and 1 teacher Islamic Education. The instruments used were validation sheets, student activity, teacher response and students. The data collection techniques used observation sheet instruments and student and teacher response questionnaires. The analysis used is descriptive qualitative statistical analysis. Based on the results of research and development shows that the media developed after validation is declared valid and reasonable for testing. The results of testing practicality show that the web-based learning media is practical because it has fulfills the criteria with the results: 1) students' activities in learning are carried out as expected, 2) teachers give excellent responses and, 3) students provide good response to the learning media. So it can be concluded that in the development of learning media activities fulfill valid and practical criteria used in the learning process especially in PAI subjects in class VIII.
