Problem definition flexibility

In summary, separator selection calls for clear problem definition, in broad terms thorough cataloging of process information and preliminary and tentative equipment selection, followed by refinement of the initial selections through tests on an increasingly larger scale. Reliability, flexibility of operation, and ease of maintenance should be weighed heavily in the final economic evaluation rarely is purchase... 

The projects executed by the students in their final year have a primary objective of giving an integrated experience to solve complex engineering problems. Typical expectations from these projects are identification of the problem, researching the literature, problem definition, concept level design, and functional level design, implementation, demonstration, and report writing. The students have the flexibility... 

The impact that the design of a plant has on its ability to be satisfactorily controlled has motivated the development of systematic approaches to account for dynamic performance during the design process. Optimization-based approaches permit the plant design and operability criteria to be handled within a single framework, and they offer considerable flexibility in the problem definition. A caveat is that the type of control system needs to be specified, whieh needs to be borne in mind when results are interpreted. A key argument advanced in the IMC approach to... 

Geminal functional theory is a very promising research area. The different varieties of antisymmetrized products are very flexible and inherently handle difficult problems, like multideterminantal molecules. The computational effort is low compared to the quality of the solutions. The perturbation theoretical approach to SSG should essentially be possible for AGP and UAGP as well. The formal definition of GFT is a flexible framework that opens up many new opportunities for exploring the nature of solutions to the Schrodinger equation. 

Volume is the third factor that must be considered in discussing the behavior of gases. Volume describes an amount of space. For example, there are 2-liter bottles, 500-cubic-centimeter engines, 65 cubic feet of interior auto space, and 2 tablespoons of butter in a recipe. Volume units include gallons, quarts, liters, cubic centimeters, and ounces. Volume can be either fixed or elastic. A fixed volume is contained, as in a soft drink can, and has a definite size. An elastic volume is one that can change, like that of a balloon. As you consider problems involving gases, you will need to examine the issue of the flexibility of the volume. 

One of the major problems of the theory of intramolecular local mobility or kinetic flexibility lies in the establishment of the principal mechanism of mobility for the macromolecules of a given chemical structure and constitution and of local conformational microstructure. The question arises, which of the elementary acts leads to the ability of individual parts of the macromolecule for changing their shape during definite time intervals characteristic of a certain class of motions 38-148)...
