This paper presented a novel sacrificial electrode dielectrophoresis method which was able to fabricate a large amount of totally discrete SWNT devices on a single chip synchronously. The discrete devices included a pair of W/Au opposed electrodes and SWNT bundles that were assembled between electrodes by DEP. We used Al lines to connect the two electrodes of all devices to two large Al pads. AC DEP...
To the feature of service database of tourist attraction and hotel in tourism field,system framework and implementation of tourist attraction, hotel QA system based on short message is described, in which attraction and hotel information is stored in database. Attraction and hotel are defined as domain entity, entity property, property category and property value. According to the characteristics...
In the design cycle of produce, virtual assembly can help to improve design quality and reduce assembly cost. A script-driven virtual assembly simulation system based on assembly sequence concurrent planning is proposed. The architecture of script-driven virtual assembly simulation system is set up. In this architecture, assembly script language and script interpreter is the key functional module...
The development of virtual assembly platform (VAP) is discussed. It is a virtual environment on PC for training system that allows training supervisors to create training instructions and allows trainees to learn assembly operations. The models and the planning methods of assembly sequence and path are described. The virtual assembly simulation scenic framework is set up, and the level of detail technology...
This paper puts forward the architecture of integrated virtual equipment simulation system based on the ideas of advanced manufacturing technology, and analyses the key techniques to be implemented among the system module. Taking use of the development kits, such as Open Inventor and Visual Studio.net, we have carried out the system that have the functions, including virtual assembly simulation, engineering...
It is the foundation of developing virtual prototype to construct assembly model. On the basis of that the advantages and disadvantages of the existing assembly model are pointed out through studying on relational models separately, a new virtual assembly model based on scene graphics technology of extensible group node, which is suitable to personal computer, is brought forward. Using this new scene...
