Virtual Design Environment

Ideally, when ligand-based or structure-based models are developed for all members of a gene family, the validated models can be used as part of the multiobjective function in a comprehensive chemical library design environment. Like other factors discussed earlier, the predicted activities can be used in the weighted objective function. Compound library design or virtual screening can be achieved by optimizing the total objective function. 

As a special form of cooperation, collaborative Virtual Reality environments were introduced. VR communication can be considered as an additional component in the tool chain for the support of communication of designers. However, due to the complex nature of the analysis process, special technology as discussed in this section has to be applied. Thus it is impossible to integrate this technology so tightly within KomPaKt as it was possible for the other forms of direct communication. 

Collaborative Virtual Reality environments are needed for such complex tasks as designing and optimizing an extruder by studying the flow phenomena in detail. Although visualization is much more complex in this case, it was shown that event sharing can be used also in distributed VR applications. Studying the impact on and the possibilities of VR in specific development processes is a rather new field of research in engineering and computer science. 

Aspects of asynchronous and synchronous object management in a distributed environment and the data models for the manipulation of lead time have thus far been in the foreground in systems for designing objects in a virtual work environment. Here, the data models are oriented by existing CAD standards or they focus on application protocols for the product data model STEP, with these protocols still to be developed. These systems are also not frilly immersive, but they are monitor based in connection with relevant 3D input tools (e.g., space mouse, trackball). Handling aspects of virtual prototypes in an immersive VE have been studied, for example, at the University of Wisconsin-Madison (Dani and Gadh 1996).

The controller implementation in the embedded system uses a rapid protot5q)ing technique, which allows, along with the virtual simulation environment, the development of a controller design for mobile robots. After being tested and validated in the simulator, the control system is programmed into the memory of the embedded mobile robot board. In this way, time and material are economized by first virtually validating the entire model and then operating the physical implementation of the system. 

Plastics behavior in fire depends upon the nature and scale of the fire as well as the surrounding conditions and how the products are designed. For example, the virtually allplastic 35 mm slide projector uses a very hot electric bulb. When designed with a metal light and heat reflector with an air circulating fan, no fire develops. Therefore, designing in this type product environment requires understanding all the variables so that the proper plastics can be used. 

Used either as prelaboratory preparation for related laboratory activities or to expose students to additional laboratory activities not available in their program, these modules motivate students to learn by proposing real-life problems in a virtual environment. Students make decisions on experimental design, observe reactions, record data, interpret these data, perform calculations, and draw conclusions from their results. Following a summary of the module, students test their understanding by applying what they have learned to new situations or by analyzing the effect of experimental errors.

Logistic environments are very complex with different design aspects like architecture, mechanics and the logic. For this task most convenient is to establish an integration tool for the final collection, simulation and real-time presentation in a virtual environment. 

The most recent National Occupational Exposure Study (NOES) conducted by NIOSH from 1981 to 1983, estimated the number of workers potentially exposed to aluminum and aluminum compounds (NIOSH 1991). Results of this survey are summarized in Table 5-8. The NOES was based on observational field surveys of 4,490 facilities and was designed as a nationwide survey based on a statistical sample of virtually all workplace environments, except mining and agriculture, in the United States where eight or more persons are employed and only provides estimates of the numbers of workers...
