Design steps

Product standards may stipulate performance characteristics, dimensions, quaUty factors, methods of measurement, and tolerances and safety, health, and environmental protection specifications. These are introduced principally to provide for interchangeabiUty and reduction of variety. The latter procedure is referred to as rationalization of the product offering, ie, designation of sizes, ratings, etc, for the attribute range covered and the steps within the range. The designated steps may foUow a modular format or a preferred number sequence. 

The filial design step is the method for physieally building the transformer for this refer to Seetion 3.5.8. 

There are many excellent textbooks on the subject of distillation, however with the explosion of information on the World Wide Web, process engineers can now gain almost instant access to calculation methods and model simulations which will walk the engineer through the important design steps. The following Web sites are recommended to be reviewed and accessed by the reader. 

Use systems that allow maximum flexibility in air flow rates and control strategies when selection of systems is based on inaccurate (preliminary) data on production processes, volumes, and raw materials to be used in the building. Emission rates from these processes and total loads might he changed during the detailed design step. 

The usual total condenser will follow the following design steps ... 

Designs can be prepared once soil resistivities and groundbed locations have been determined. Figure 10.23 illustrates typical installations. Design steps are as follows ... 

Any ATES realization is a quite complex procedure and has to follow a certain pattern to be proper developed. Typical designing steps are as follows ... 

Our models center on either the behavior expected of individual objects (large and small) or the designs for how groups of objects collaborate. Each of the primary abstractions— type and collaboration—has two main forms of refinement. Collaboration refinements affect multiple participants in the collaboration type refinement should not affect a client in any way. Most design steps are a combination of these basic four varieties. 

This final Pures step is the last stage of manufacture for the API and may be considered as the API Product design step. It will be the focus of this chapter s case study, using the generic drug molecule Cimetidine as an example. 

The following section focuses specifically on those design strategies that produce either monoliths or supported films that may then serve as a solid but textured platform in the first design step toward a 3-D battery architecture. 

Tolerance design - if the parameter design step did not achieve the required results then this step can be used to decrease tolerances in the production, which involves however a cost increase... 

Especially the parameter design step gives the best opportunity to incorporate and/or to increase the quality of a product or process. Therefore the rest of this part concentrates on the parameter design step. 

Noise factors - factors that normally cannot be controlled, however for the experimental part of this design step the noise factors must be controlled to determine their possible effects. 

In order to achieve the best quality of a process or a product, the design step of the process or product is a very important one. Most of the quality needed later can be built into the product at the design stage. Here, the best quality is defined as obtaining or approaching as close as possible those characteristics which are desired. Moreover, one wishes to keep close to these properties when variations in process conditions appear, or when a product deteriorates through use or ageing, or when external (environmental or noise) factors affect the product. 

Fig. 16.8. Reactant-level (pre-enumeration) design steps. This is a screen shot of PGVL Hub during the design of the two libraries. The reactant sets for this two-component reaction and the generated explicit libraries and products are all captured during the design session (see the left-hand side). The -component is for acids and the B-component for amines. The molecular structures of the two special acids are shown in Fig. 16.6. Many annotations can be added to reactants to aid their analysis and selection. Here ClogP, molecular weight (MW), similarity (SIMI) with respect to a user-defined reactant, and reactant amount available in the inventory house are just a few examples.

The next libraries were designed step-wise on the basis of knowledge gained from previous ones. As such, the second, third and fourth libraries were based on platinum-ceria, metal oxide-ceria and copper-ceria formulas, respectively, each of them using a similar DoE model for their design [18].
