Partial design

Within the effects clause, there is no strong difference between participants and parameters both can be affected by the action. The distinction is intended to document a partial design decision. The participants exist or will be built as separate entities, with some direct or indirect interaction between them to realize the action. Together, the parameters represent information that is passed between the participants, encoded in a form not documented here, and possibly communicated differently. [Pg.187]

The design of any system embodies several partial designs of how the pieces collaborate. These designs constitute some of the key architectural elements used in the system design. The resulting design is a composition of these partial collaborations, unified via objects that participate in more than one collaboration. The architecture is often best described and understood in terms of recurring patterns of such collaborations. [Pg.532]

In Chapter 3 the basic equations for reactions and reactors are set up the objective function needed to define a realistic optimal problem is discussed in Chapter 4. Subsequently, it is natural to consider separately the main types of chemical reactors and their associated problems. In Chapter 8 three problems with a stochastic element in them are described. Chapter 9 concerns itself with the optimal operation of existing reactors which may be regarded as partial designs in which only some of the variables can be optimally chosen. Some recent advances in optimal control, which, however, lie outside our present considerations, are to be found in the paper by Kalman, Lapidus, and Shapiro (1959) and in that of Rudd, Aris, and Amundson (1961). [Pg.10]

Partial design specification The user should be able to specify a partially designed structure as an initial constraint the synthesis tools should then be able to complete the rest of the design. [Pg.10]

These positive traits come at costs in terms of dielectric and piezoelectric constants when compared with traditional piezoceramics (lead zirconate tilanales and modified lead titanates). However, the low material properties can be partially design compensated for in many applications. [Pg.736]

Partially vaporized feed reverses these effects. For a given separation, the feed conditions can be optimized. No attempt should be made to do this at this stage in the design, since heat integration is likely to change the optimal setting later in the design. It is usually adequate to set the feed to saturated liquid conditions. This tends to equalize the vapor rate below and above the feed. [Pg.78]

These small positive and negative errors partially cancel each other. The result is that capital cost targets predicted by the methods described in this chapter are usually within 5 percent of the final design, providing heat transfer coefficients vary by less than one order of magnitude. If heat transfer coefficients vary by more than one order of magnitude, then a more sophisticated approach can sometimes be justified. ... [Pg.232]

The authors emphasize on their web pages that UFF is not designed to be used in conjunction with partial atomic charges, as it is the default option in several software packages. A second point is that UFF is often used to model biological... [Pg.350]

According to general usage, the term cyanine designates any cationic dye in which two nuclei of different or same nature are linked by a mono or polymethine chain. When these groups (-CH= are replaced partially or totally by one or several nitrogen atoms, the cationic dye is called azacyanine. [Pg.25]

Both objectives have been met by designing special hydrogenation catalysts The most frequently used one is the Lindlar catalyst, a palladium on calcium carbonate combi nation to which lead acetate and quinoline have been added Lead acetate and quinoline partially deactivate ( poison ) the catalyst making it a poor catalyst for alkene hydro genation while retaining its ability to catalyze the addition of H2 to the triple bond... [Pg.375]

Other correlations based partially on theoretical considerations but made to fit existing data also exist (71—75). A number of researchers have also attempted to separate from a by measuring the latter, sometimes in terms of the wetted area (76—78). Finally, a number of correlations for the mass transfer coefficient itself exist. These ate based on a mote fundamental theory of mass transfer in packed columns (79—82). Although certain predictions were verified by experimental evidence, these models often cannot serve as design basis because the equations contain the interfacial area as an independent variable. [Pg.37]

A number of flume designs have been created specifically for use in partially fiUed circular conduits such as sewers. These are available in molded fiber glass and can be lowered through a manhole if required. As with all open-channel head-area meters, flumes must be sized to prevent submergence of the restriction. [Pg.63]

Current Meters. Various vane designs have been adapted for open-channel flow measurement. The rotating element is partially immersed and rotates rather like a water wheel. Operation is similar to that of vane anemometers. [Pg.63]

Several special forms of electromagnetic flow meters have been developed. A d-c field version is used for Hquid metals such as sodium or mercury. Pitot and probe versions provide low cost measurements within large conduits. Another design combines a level sensor and an electromagnetic meter to provide an indication of flow within partially full conduits such as sewer lines. [Pg.65]
