Design choices

Simulation tools are available for sizing and analyzing plants. However, these tools do not replace the designer as the architect of the plant because selection of process and the sequenciag of units are the designers choices. The same is tme for heat-exchanger networks. Most of the commercial process simulator companies market computer modules that perform some of the tedious steps ia the process but none is able to remove the designer from the process. [Pg.518]

Because of the inherently greater susceptibility of expansion bellows to failure from unexpected corrosion, failure of guides to control joint movements, etc., it is advisable to examine critically their design choice in comparison with a stiff system. [Pg.1002]

Whenever you have to report on the structure of an alloy - because it is a possible design choice, or because it has mysteriously failed in service - the first thing you should do is reach for its phase diagram. It tells you what, at equilibrium, the constitution of the alloy should be. The real constitution may not be the equilibrium one, but the equilibrium constitution gives a base line from which other non-equilibrium constitutions can be inferred. [Pg.25]

This information will sufficiently define the function so that a design can be started. It defines the environment, sets the load level and the type of loading situation, and gives some idea of the shape requirements, as well as the possible aesthetics of the unit. It still permits a wide range of design choices as to material, structure, and shape but they would be limited to those normally used in a library environment. The more accurately and completely the function is defined, the more restricted are the design possibilities and the more detailed the specifications for the function. [Pg.204]

An understanding of the role of toxicokinetics and toxicodynamics in the manifestation of hazard is fundamental to designing safer chemicals and can guide early design choices. Toxicokinetics and toxicodynamics use the same principles to study toxicological phenomena as those that are used to study the therapeutic use of chemicals as medicines. Toxicokinetics is concerned with the time course of action of chemicals that involves the disposition of a chemical affected by absorption, distribution, metabohsm and excretion commonly referred to by the acronym ADME. [Pg.33]

Compost bins can be purchased or homemade, and are preferably made from recycled or reused materials. As long as it fulfills the basic criteria right), the design choice is yours. Choose one that suits your needs and garden. Place it in an accessible spot, directly on bare ground. It can have a fixed site or, depending on the model, it can be moved to different parts of the garden between batches. [Pg.41]

Hie garden framework Lumber and stone usually make up the "hard landscaping" of the garden, while plants could be termed the "soft furnishings." There are design choices to be made hedges and lawns, for example, are "soft" alternatives to fences and paving. [Pg.126]

Thus simulation (e.g., the feasibility test in Section III,A,1 with area constraints replacing the ATm constraints) and costing should be used to evaluate the final design choices. [Pg.85]

Embedded entropy and complexity must be viewed as an investment when making design choices on recycle, reuse, or beneficial disposition. [Pg.49]

This length is within the 2.438-m requirement, so the final design choice is ... [Pg.543]

It is important to recognize that the plan to use carbon in ITER follows directly from the projected levels of thermal loads expected during plasma thermal transient events (e.g., type I ELMs and disruptions). Thus, efforts to better characterize power deposition during disruptions and ELMs, as well as to reduce ELM heat loads and to mitigate disruptions (see, for example, [55]) are very important due to the influence on these design choices. [Pg.296]

To optimize the neural network design, important choices must be made for the selection of numerous parameters. Many of these are internal parameters that need to be tuned with the help of experimental results and experience with the specific application under study. The following discussion focuses on back-propagation design choices for the learning rate, momentum term, activation function, error function, initial weights, and termination condition. [Pg.92]

Throughout the whole of this, you should be getting data on cost that will largely determine your design choices. [Pg.147]
