Computational Fluid Dynamics (CFD) analyses of individual flow channels in a solid oxide electrolyzer cell are being used to model temperature, current density, and local hydrogen production. In 2004, the integrated performance of an HTE plant and the thermal optimisation of the plant through various component arrangements were modeled. In addition, solid oxide electrolyser cell electrode materials with improved durability in the variable environment of the electrolyser cell are currently being developed. 

Besides the statistical prediction of biological activity based on the rules, the deductive inference module provides explanation of predictions. It produces a three-dimensional graphic display of biophores found in the analyzed structures and allows superimposition of compounds with the same biophore. Visualization is performed via integration with the Insight II environment from Accekys Inc. [21], a molecular modeling environment with a powerful graphical interface. 

The base case model parameters used are given in table 1. The operating parameters discussed in this work and the performance indicators used are described in table 2. The main performance indicators considered here are the conversion of A and the integral reactor selectivity. The model was implemented in the gPROMS modeling environment. 

For a variety of appHcations such as computer-aided engineering systems, software development, or hypermedia, the relational database model is insufficient. In an RDBMS, it is difficult to model complex objects and environments the various extensive tables become complicated, the integrity is problematic to observe, and the performance of the system is reduced. This led to two sophisticated object-based models, the object-oriented and the object-relational model, which are mentioned only briefly here. For further details see Refs. [10] and [11]. 

A simple model of lumped kinetics for supercritical water oxidation included in the partial differential equations for temperature and organic concentrations allows to qualitatively simulate the dynamic process behavior in a tubular reactor. Process parameters can be estimated from measured operational data. By using an integrated environment for data acquisition, simulation and parameter estimation it seems possible to perform an online update of the process parameters needed for prediction of process behavior. 

Microsoft Office allows the option to record macros for performing repetitive tasks. Although macros are somewhat limited for the development of true VBA applications, macro recording can be used effectively to learn VBA or create templates of code that can be generalized with the addition of variables. If VBA for Microsoft Office is enabled, you only need to press alt-fi i to open the VBA Integrated Development Environment (IDE). A search of the on-line help for Application Object will provide an interactive object hierarchy that describes (with detailed code examples) each object or collection. There are literally thousands of objects within the Microsoft Office application object models. Another very useful tool within the VBA environment is the Object Browser, which can be invoked with the F2 key. The Object Browser can be particularly useful to learn the objects of external components that have been referenced from within VB or VBA. This method is an excellent way to get started with new object types and follow along with the documentation. An example is shown in Figure 18.3 from the Excel 2000 VBA IDE. In this example, the Excel is the automation client and Sciex Analyst method component... 

Process integration in PRIME is based on the integration of the contextual description of the design process steps with descriptions of the tools responsible to perform these steps. A tool model is constructed in a tool modeling formalism describing its capabilities (i.e. services provided) and GUI elements (menu items, tool bars, pop-up menus etc.). Process and tool metamodels are integrated within the so-called environment metamodel (Fig. 3.3). The interpretation of environment models enables the tools to adapt their behavior to the applicable process definitions for the current process state. Thus, the user is able to better understand and control the process execution.
