Specification of objective

For many years the implementation of transportation policies, and all others, followed a logically structured cycle of allocative decisions based on a rational approach that is usually illustrated with four main steps specification of objectives development of alternatives by which the objectives may be accomplished evaluation of the consequences of each alternative and finally, selection of the action that maximizes the net benefit according to decision-makers criteria and valuations. [Pg.89]

Despite some similarities, responsibility modelling differs from goal based techniques. Whilst the notion of responsibility modelling may be viewed as incorporating the specification of objectives to be achieved, there is also an acknowledgment that in complex sociotechnical systems, the achievement of an objective (i.e. the discharge of responsibility) is subject to a range of constraints and that even with the best efforts of an... [Pg.1064]

For tire purjDoses of tliis review, a nanocrystal is defined as a crystalline solid, witli feature sizes less tlian 50 nm, recovered as a purified powder from a chemical syntliesis and subsequently dissolved as isolated particles in an appropriate solvent. In many ways, tliis definition shares many features witli tliat of colloids , defined broadly as a particle tliat has some linear dimension between 1 and 1000 nm [1] tire study of nanocrystals may be drought of as a new kind of colloid science [2]. Much of die early work on colloidal metal and semiconductor particles stemmed from die photophysics and applications to electrochemistry. (See, for example, die excellent review by Henglein [3].) However, the definition of a colloid does not include any specification of die internal stmcture of die particle. Therein lies die cmcial distinction in nanocrystals, die interior crystalline stmcture is of overwhelming importance. Nanocrystals must tmly be little solids (figure C2.17.1), widi internal stmctures equivalent (or nearly equivalent) to drat of bulk materials. This is a necessary condition if size-dependent studies of nanometre-sized objects are to offer any insight into die behaviour of bulk solids. [Pg.2899]

The importance of the characters of the symmetry operations lies in the fact that they do not depend on the specific basis used to form them. That is, they are invariant to a unitary or orthorgonal transformation of the objects used to define the matrices. As a result, they contain information about the symmetry operation itself and about the space spanned by the set of objects. The significance of this observation for our symmetry adaptation process will become clear later. [Pg.586]

These six matrices form another representation of the group. In this basis, each character is equal to unity. The representation formed by allowing the six symmetry operations to act on the Is N-atom orbital is clearly not the same as that formed when the same six operations acted on the (8]s[,S 1,82,83) basis. We now need to learn how to further analyze the information content of a specific representation of the group formed when the symmetry operations act on any specific set of objects. [Pg.586]

MultiwaU. shipping sacks are suitable for transport in aU kinds of carriers from tmcks to seafaring vessels. Particular care must be taken to prevent the storage of objects with sharp projections adjacent to the bags in case of doubt, it is advisable to line the enclosure with kraft paper of a basis weight >23 kg. Additional rules for the transportation of multiwaU sacks are contained in appHcable tariff specifications and should be consulted for rail, tmck, and ocean-going shipments. [Pg.514]

No single method or algorithm of optimization exists that can be apphed efficiently to all problems. The method chosen for any particular case will depend primarily on (I) the character of the objective function, (2) the nature of the constraints, and (3) the number of independent and dependent variables. Table 8-6 summarizes the six general steps for the analysis and solution of optimization problems (Edgar and Himmelblau, Optimization of Chemical Processes, McGraw-HiU, New York, 1988). You do not have to follow the cited order exac tly, but vou should cover all of the steps eventually. Shortcuts in the procedure are allowable, and the easy steps can be performed first. Steps I, 2, and 3 deal with the mathematical definition of the problem ideutificatiou of variables and specification of the objective function and statement of the constraints. If the process to be optimized is very complex, it may be necessaiy to reformulate the problem so that it can be solved with reasonable effort. Later in this section, we discuss the development of mathematical models for the process and the objec tive function (the economic model). [Pg.742]

The results of the Flixborough investigation made it clear that the large inventory of flammable material in the process plant contributed to the scale of the disaster. It was concluded that limitations of inventory should be taken as specific design objectives in major hazard installations. It should be noted, however, that reduction of inventoiy may require more frequent and smaller shipments and improved management. [Pg.2306]

This sample, referred to in Chapter 2, can serve as a guide for planning and conducting assessments of tollers. It may require additions, revisions, or other modifications in order to meet the needs of facility specific assessment objectives, the facility setting, or other special circumstances. This sample includes ... [Pg.179]

The term objectives is not defined in ISO 8402 but in ISO/DIS 9000 2000 (soon to replace ISO 8402) quality objectives are defined in ISO 9004 as key elements of quality such as fitness of use, performance, safety, and reliability. It also mentions the calculation and evaluation of costs associated with all quality objectives. It goes on to suggest that specific quality objectives be documented and be consistent with quality policy as well as other objectives of the organization. You can then go on to set new objectives. [Pg.103]

On the due date when the tenders should have been received, record those that have been submitted and discard any submitted after the deadline. Conduct an evaluation to determine the winner - the subcontractor that can meet all your requirements (including confidence) for the lowest price. The evaluation phase should involve all your staff that were involved with the specification of requirements. You need to develop scoring criteria so that the result is based on objective evidence of compliance. [Pg.319]

Crystallization process control is desirable from a number of standpoints. The primary objective is often to meet customer requirements by achieving consistent product quality to a desired specification of crystal size, size distribution and purity. Secondly, process requirements often dictate maintenance of stable crystallizer operation, the avoidance of fines and encrustation, and the minimization of subsequent downstream processing. [Pg.287]

As Watanabe s Ugly Duckling Theorem reminds us, there can never be a rigorously objective way to ascribe a ineasnre of similarity (or dissimilarity) between any two randomly chosen subsets of a given sc t. An asymmetry can be induced only via some external aesthetic measure. The absolute validity of any partitioning of the world into a specific set of objects and rela tions - which, as we have argued, constitutes the very essence of physics - is therefore, fundamentally, arbitrary. ... [Pg.700]

Objective Evaluation of Color. In recent years a method has been devised and internationally adopted (International Commission on Illumination, I.C.I.) that makes possible objective specification of color in terms of equivalent stimuli. It provides a common language for description of the color of an object illuminated by a standard illuminant and viewed by a standard observer (H). Reflectance spectro-photometric curves, such as those described above, provide the necessary data. The results are expressed in one of two systems the tristimulus system in which the equivalent stimulus is a mixture of three standard primaries, or the heterogeneous-homogeneous system in which the equivalent stimulus is a mixture of light from a standard heterogeneous illuminant and a pure spectrum color (dominant wave-length-purity system). These systems provide a means of expressing the objective time-constant spectrophotometric results in numerical form, more suitable for tabulation and correlation studies. In the application to food work, the necessary experimental data have been obtained with spectrophotometers or certain photoelectric colorimeters. [Pg.7]

By the end of the text you should appredate the enormous potential that biological systems have for making a wide range of products and to achieve a variety of objectives. You should also have knowledge and be able to dte specific examples, of how economic, sodal and political attitudes may impinge upon the adoption of the technology. [Pg.9]

The word ontology has a long history in philosophy, in which it refers to the study of being as such. In information science, an ontology is an explicit formal specification of how to represent the objects, concepts, and other entities that are assumed to exist in some area of interest and the relationships among them. [Pg.902]

As a result the research emphasis in this field focused on efforts to design experiments in which it might be possible to determine to which one of the foregoing three rate equations the observed second-order rate coefficient actually corresponded. More specifically, the objective was to observe one and the same system first under conditions in which complex decomposition (fcp) was rate-determining and then under conditions in which complex formation (kF) was ratedetermining. A system in which either formation or decomposition was subject to some form of catalysis was thus indicated. In displacements with primary and secondary amines the transformation of reactants to products necessarily involves the transfer of a proton at some stage of the reaction. Such reactions are potential-... [Pg.409]

The maturity of dendrimer chemistry has led to confusion among researchers, because there are no specific research objectives in this field. It may be a good idea to design and synthesize a novel macromolecule, a non-dendrite-shaped molecule, keeping the concept of the dendrimer in mind. The nano-sized closed space inside the molecule is one of the key concepts for novel macromolecular chemistry. [Pg.84]
