The LAB@FUTURE Project - Moving Towards the Future of E-Learning

This paper presents Lab@Future, an advanced e-learning platform that uses novel Information and Communication Technologies to support and expand laboratory teaching practices. For this purpose, Lab@Future uses real and computer-generated objects that are interfaced using mechatronic systems, augmented reality, mobile technologies and 3D multi user environments. The main aim is to develop and demonstrate technological support for practical experiments in the following focused subjects namely: Fluid Dynamics - Science subject in Germany, Geometry - Mathematics subject in Austria, History and Environmental Awareness – Arts and Humanities subjects in Greece and Slovenia. In order to pedagogically enhance the design and functional aspects of this e-learning technology, we are investigating the dialogical operationalisation of learning theories so as to leverage our understanding of teaching and learning practices in the targeted context of deployment

Distributed VR-based simulation for manufacturing

VR-based simulation has been applied to a wide range of industrial applications. The rapid development of networking and Internetworked 3D graphics techniques has already begun to foster the distributed VR-based simulation system. The WWW as the delivery mechanism has made the VR-based simulator widely available and affordable. In this paper, we propose a cost-effective approach to create distributed VR-based simulation systems for manufacturing applications. Using this approach, three VRML manufacturing simulators machining, process flow, factory layout, are described in detail. The current challenges of a distributed VR-based simulator are also discussed

The objective of the new framework is to enable the satisfaction of performance requirements on autonomous vehicles and robots in space exploration, deep underwater exploration, defense reconnaissance, automated manufacturing and household automation

IC.IDO as a tool for displaying machining processes. The logic interface between Computer-Aided-Manufacturing and Virtual Reality

Abstract This scientific communication investigates the logic interface of a CAM solver, i.e., MasterCAM, into a Virtual Reality (VR) environment. This integration helps in displaying machining operations in virtual reality. Currently, to partially visualize the results of a simulation in an immersive environment, an import/export procedure must be done manually. Here, a software plugin integrated into IC.IDO (by ESI Group) has been realized and fully described. This application allows the complete integration of CAM solver into the VR environment. In particular, the VERICUT solver has been integrated into VR. This kind of integration has never been done yet

A CAD-based modeling for dynamic visualization of urban environments in piecemeal (incremental) growth

Thesis (Master)--Izmir Institute of Technology, City and Regional Planning, Izmir, 2002Includes bibliographical references (leaves: 114-122)Text in English; Abstract: Turkish and Englishxi, 122 leavesVisualization is inherent to the conduct of urban design as a direct connection between the designer and three dimensional reality of urban settlements. Visualization of urban environments and urban design projects is vital, since most designers prefer to understand place and context through visualization. The reasons for visualization in urban design can be classified under three headings: .visual thinking, design communication and testing mechanism. Digital revolution. has improved computer use in urban design, as in many other fields. Dynamic computer models can present an ideal environment to visualize the change in respect to time. Digital tools are much more efficient than conventional methods in explaining the growth and change of urban environments. Especially, incremental growth requires features not found in .static/analog. media. Christopher Alexander and his colleagues, in their book .A New Theory of Urban Design., tried to justify their ideas about piecemeal growth by an experiment. The analog methods, such as physical models, two-dimensional diagrams, have been used to conduct the experiment and to convey their ideas about the design process. This thesis tries to produce a .dynamic/digital. model that could be utilized in their experiment instead of static/analog methods. Spatial data should be considered as dynamic, or changing identities rather than as simple, static features. Time is an example of a dynamic component of a spatial data set. Recent technological developments are increasing computer hardware and software capabilities so that this dynamic aspect of data can be accounted for by today.s systems. Dynamic data have not been a great concern in digital technologies for many years, but today changing patterns and dimensions are becoming more important

An integrated framework for developing generic modular reconfigurable platforms for micro manufacturing and its implementation

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.The continuing trends of miniaturisation, mass customisation, globalisation and wide use of the Internet have great impacts upon manufacturing in the 21st century. Micro manufacturing will play an increasingly important role in bridging the gap between the traditional precision manufacturing and the emerging technologies like MEMS/NEMS. The key requirements for micro manufacturing in this context are hybrid manufacturing capability, modularity, reconfigurability, adaptability and energy/resource efficiency. The existing design approaches tend to have narrow scope and are largely limited to individual manufacturing processes and applications. The above requirements demand a fundamentally new approach to the future applications of micro manufacturing so as to obtain producibility, predictability and productivity covering the full process chains and value chains. A novel generic modular reconfigurable platform (GMRP) is proposed in such a context. The proposed GMRP is able to offer hybrid manufacturing capabilities, modularity, reconfigurablity and adaptivity as both an individual machine tool and a micro manufacturing system, and provides a cost effective solution to high value micro manufacturing in an agile, responsive and mass customisation manner. An integrated framework has been developed to assist the design of GMRPs due to their complexity. The framework incorporates theoretical GMRP model, design support system and extension interfaces. The GMRP model covers various relevant micro manufacturing processes and machine tool elements. The design support system includes a user-friendly interface, a design engine for design process and design evaluation, together with scalable design knowledge base and database. The functionalities of the framework can also be extended through the design support system interface, the GMRP interface and the application interface, i.e. linking to external hardware and/or software modules. The design support system provides a number of tools for the analysis and evaluation of the design solutions. The kinematic simulation of machine tools can be performed using the Virtual Reality toolbox in Matlab. A module has also been developed for the multiscale modelling, simulation and results analysis in Matlab. A number of different cutting parameters can be studied and the machining performance can be subsequently evaluated using this module. The mathematical models for a non-traditional micro manufacturing process, micro EDM, have been developed with the simulation performed using FEA. Various design theories and methodologies have been studied, and the axiomatic design theory has been selected because of its great power and simplicity. It has been applied in the conceptual design of GMRP and its design support system. The implementation of the design support system is carried out using Matlab, Java and XML technologies. The proposed GMRP and framework have been evaluated through case studies and experimental results

Online Interior Design for Malay Traditional House

'Online Interior Design' focused on Malay Traditional House in Malaysia. The project is an online system in which user can access and view the system as well as perform some functions provided by the system via Internet. The project is for Interior Design Company in Malaysia that designs the interior ofMalay House Traditional or any other house that wants Malay Traditional House concept. The main focus of the project is how usercaninteract withthe system to design anddecorate the internal house virtually. The objective of the project is to enable user to interact with virtual house by manipulating the object, navigating the environment and selecting the object they want in order to decorate the environment of the house. Sincethere has manytype of houses in Malaysia such as Pahang Traditional House or Malacca Traditional House, the scope of the project is focusing onMalay Traditional House generally, not specifically like Pahang Traditionally House. The general Malay Traditional House is designed based onMalay Traditional House architecture which include 'anjung', 'serambi', 'rumah ibu' or 'kitchen'. Virtual Reality Modeling Language (VRML) is used to design object of the virtual house assisted by the imported 3D objects. VRML's Scene Description Language and, VRML Script Node methods are combined together to allow interaction between user and the virtual house besides allowing user to manipulate the objects. The project methodology used is System Development Life Cycle (SDLC) that showed how the project is designed and developed as well as the flow of the process. The project is to vary the taste of people in decorating their house andit also can be applied to alltype of houses that want to have MalayTraditional Houseinterior design.
