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. [Pg.22]

We then embed this system model into a statistical analysis and 3D interactive multimedia framework (Figure 1). We use statistical methods to capture processes before they go out of control as well as to perform trend analysis, a great opportunity for innovation, and use 3D interactive multimedia and 3D visualization methods over the Web for communication purposes with global innovation team members. The emphasis on collaboration in today s competitive medical drug held requires these virtual environments to streamline team interaction. (Note that the active... [Pg.173]

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. [Pg.389]

This paper has discussed algorithms for rendering reverberation in real-time. A straightforward method for simulating room acoustics is to sample a room impulse response and render the reverberation using convolution. Synthetic impulse responses can be created using auralization techniques. The availability of efficient, zero delay convolution algorithms make this a viable method for real-time room simulation. The drawback of this method is the lack of parameterized control over perceptually salient characteristics of the reverberation. This can be a problem when we attempt to use these systems in interactive virtual environments. [Pg.81]

The use of multiple senses in chemistry experiments represents a more effective approach at mentally stimulating students and provides a better opportunity for memory retention as suggested by the effects of multisensory input in virtual environment experiments (Dinh et al. 1999). Research shows that olfactory stimuli enhance memory recognition (Cann and Ross 1989) and that once an aroma is retained, there is long-term resistance to distortion (Engen and Ross 1973). Coupling the sense of smell to hearing and touch provides a powerful combination to explore chemical principles in the laboratory. [Pg.213]

An entirely different type of software advance is in the area of modeling drug metabolizing enzymes to predict whether a discovery compound will be a substrate for a particular enzyme for example, the polymorphic enzyme CYP2D6 [123,124]. In addition, software companies, such as Camitro Corp (see Chap 1), are developing software to predict the site(s) and rates of oxidative metabolism by modeling the major cytochrome P450 enzymes. Both of these innovative approaches allow thousands of compounds to be screened in a virtual environment with minimal use of laboratory experiments to make decisions. [Pg.327]

The photoresist technologies involve many steps each can be characterized by many parameters. It is very difficult to optimize the processes. Previously used pilot experiments now proved to be very costly and difficult. It is not possible to optimize all parameters by performing large series of the lithography experiments, at all possible sets of the parameters. The problem may be simplified and sometimes completely solved by means of mathematical modeling and simula-tion.f ° Photoresist technology simulation provides the opportunity to perform experiments in a virtual environment that can be much faster and cheaper than the full-scale wafer experiments. [Pg.2124]

Although this is already possible in room mounted Virtual Environments, such as CAVE-like or workbench environments, these setups are typically optimized for single users. As such, they have a little drawback for the cooperative work of many users. More possibilities result from the idea of Collaborative Virtual Environments (CVE), where more than one Virtual Environment is coupled on an application level and users interact remotely through teleconferencing mechanisms, avatar representations, and specific interaction metaphors. [Pg.281]

As in other application areas that examine flow phenomena, in plastics processing numerical simulations replace the common model-based experiment. With increasing complexity, the requirements on the methods for the visualization rise. Traditionally, visualization software allows the simple animation of transient data sets. This is not enough for the interactive exploration of complex flow phenomena, which is, in contrast to a confirmative analysis, comparable to an undirected search in the visualization parameters for a maximum insight into the simulation. In a worst case scenario, important features of a flow are not detected. Due to this fact, the interactive explorative analysis in a real-time virtual environment is demanded by scientists. [Pg.285]

In the field of Virtual Environments, this is a severe constraint, as these applications require a real-time environment to run in. This can usually not be fulfilled and is stated in the Consistency-Throughput Tradeoff [966] It is impossible to allow dynamic shared state to change frequently and guarantee that all hosts simultaneously access identical versions of that state . As such it states that a dynamic VE can not support dynamic behavior and consistency across all connected sites simultaneously. [Pg.288]

Fig. 7.8.9 illustrates the basic principle of a video sensor. The ECU extracts different predictors from the received image like the lane markings, speed limits, or the distance to objects ahead. These data enable the system to construct a virtual environment around the car. From the specified locations of objects in this environment, possible vehicle interactions can be derived. [Pg.396]

The procedure seems to be strange at the first glance because we are taking a function where we add in fact a certain energy form to the energy of the system. However, the interpretation that we are adding up a virtual environment makes this procedure plausible. [Pg.214]

Abstract The wave function of Coulson and Fischer is examined within the context of recent developments in quantum chemistry. It is argued that the Coulson-Fischer ansatz establishes a third way in quantum chemistry, which should not be confused with the traditional molecular orbital and valence bond formalisms. The Coulson-Fischer theory is compared with modern valence bond approaches and also modern multireference correlation methods. Because of the non-orthogonality problem which arises when wave functions are constructed from arbitrary orbital products, the application of the Coulson-Fischer method to larger molecules necessitates the introduction of approximation schemes. It is shown that the use of hierarchical orthogonality restrictions has advantages, combining a picture of molecular electronic structure which is an accord with simple, but nevertheless empirical, ideas and concepts, with a level of computational complexity which renders praetieal applications to larger molecules tractable. An open collaborative virtual environment is proposed to foster further development. [Pg.269]

In this chapter, we propose the creation of a new collaborative virtual environment for the development of the Coulson-Fischer method for molecular wave functions. It is proposed that this environment should be open. This chapter gives some background to the project. [Pg.270]
