This paper focuses on analyses of the feasibility of telerobotic and autonomous systems in hazardous environments. The hazardous environments are divided into three missions: area clearance, removal of unexploded ordnance, and hazardous waste removal. This paper identifies the factors impacting military's missions on various operating systems. Then, a decision support system based on fuzzy logic is developed for studying these factors to determine the feasibility of automating military's environmental restoration operations. The last part of the paper provides a set of recommendations for technology policy development.
The V.C.net project is an Internet-based educational and communication tool for the architectural community. Its goal is to encourage students from architecture programs across the country and around the world to examine problems and collaborate in the exploration of ideas through the World Wide Web. The central concept of the project involves the creation of a simulated, vital urban environment constructed from various forms of digital data. This 'virtual city' will be comprised of projects executed by students of architecture and urban design in US and abroad. Projects will be proposed for specific sites and will reflect real-world questions as they are mirrored in the virtual world. The city exists as a heuristic tool and is not intended as a copy of any existing human habitat. The ultimate goal of the project is to create a dynamic platform to study the interrelationship of various forces effecting urban development: architecture, planning, civil engineering, economics, social sciences, etc. The project originates at the School of Architecture of the University of Detroit Mercy and is intended to be truly interdisciplinary.
The paper describes a new approach to programming construction robots, using virtual reality (VR) techniques. The new approach is needed because both traditional and new methods of programming industrial robots, described in the paper, have specific drawbacks, which become crucial in the construction arena. This is because of the ever-changing environment of construction and its nature, a prototype or one-of-a-kind, industry. As a result, construction robots need much more programming than their industrial counterparts, which is labor intensive using known methods and is not compensated by mass production. The VR approach is demonstrated with the Multi-Purpose Interior Finishing Robot (MPIR) for a masonry task, accompanied by a detailed description of the VR-based programming model and approach.
This work presents a tool for analysing the figurative structure of architectural façades. The procedure begins by singling out the elementary shapes which make up the façade image; it detects and identifies them as "area objects", even if present in combination in virtual or mental form and groups them into classes of equal objects. A second step is the analysis of the inner structure of the classes: equidistant, arithmetical and geometrical sequences, or alternate distances are distinguished. The procedure ends by singling out the symmetries which structure the façade image and displaying them, pointing out their implied hierarchy through a thickness differentiation.
Few publications on technology are read from start to finish and, where a broad subject is covered, only part of the content is relevant to a particular reader. Facilities such as multimedia and hypertext allow documents from different sources and containing various forms of data to be linked into a report which can be published electronically. Those who access a report, such as Building IT 2005, can then go direct to the topics of particular interest, visit related topics and background data, or search the text for particular terms. The most appropriate medium can be used whether text, data, images or video, and useful material extracted for teaching or research. Actions can be linked back to the papers in which they were recommended so that, while conclusions are presented compactly, the full context and the credentials of the author can be seen.
