Coding and symbols

Factorial designs are usually discussed in terms of coded factor spaces. Table 14.1 shows some of the common coding systems for two- and three-level designs. Our emphasis in this chapter will be on the two-level designs. 

Common coding systems for two- and three-level factorial designs. 

To complicate matters, however, the notation for a design point is also used as a symbol for the response at that factor combination. Thus, ac might refer to the design point (the factor combination) at which an experiment was carried out, or ac might refer to the response that was obtained there. It is usually clear from the context which meaning should be attached to the symbol. 

The first column of Table 14.2 lists the experiment numbers (1-8). The next three columns list the abbreviated coded factor levels (- and +) for factors A, B, and C. Note that these three columns are equivalent to the abbreviated coded D matrix  

The next column lists the factor combinations (again, each symbol is equivalent to a description of the factor combination represented by the design point). The last column gives the response and is equivalent to the matrix of measured responses, Y

These structural characteristics can be easily represented by using specific codes and symbols, which can be very useful for a compact presentation and comparison of the structural features of several structures. Many different notations have been devised to describe the stacking pattern (for a summary see Parthe 1964, Pearson 1972). A few of them will be presented here. 

A maximum number of eleven modelling teams have participated in the different benchmark activities related to the FEBEX test. Their names, codes and symbols used in the presentation of results are given in Table 3. 

Lack of convention and standardization of codes and symbols has caused a great deal of confusion and impatience with analytical chemists from the outside world. A quick, simplistic view of the situation can erroneously lead one to think an agreed upon, standardized convention and one that is universally accepted Is not that difficult a task. 

The reliance upon expectation is an essential mechanism in skilled operation and many tasks would take a great deal longer to carry out if this was not so. Thought therefore needs to be given to ways in which reality can be made to fit people s models, rather than vice versa. Standardisation of machine controls, layout of work places, colour coding and symbols, etc. 

For each structural descriptor, its digital code and symbol are indicated. 

The scope covers many other less basic exclusions, and inasmuch as the scope is occasionally revised, except for the most obvious cases, it is prudent to review the current issue before specifying or designing pressure vessels to this division. Any vessel which meets all the requirements of this division may be stamped with the code U symbol even though exempted from such stamping. 

In spatial OSDs the flow of events and symbols is overlaid on a map of all items of equipment with which the operator interacts during the task. The map itself does not have to be very accurate, provided that the general geographical relationships among items of equipment are shown. The spatial OSD thus provides a graphical description of the perceptual-motor load a particular task imposes on the performance of the worker. For multiperson tasks, the operational sequences for several workers can be coded in different colors and superimposed onto the same equipment map. This can generate useful information for the distribution of tasks to different members of the operating team. 

This handbook is an invaluable tool for those seeking to understand the profound and mysterious art of alchemy. It contains a comprehensive dictionary of alchemical terms, guide to alchemical ciphers and symbols, charts of alchemical correspondences, and a free downloadable TrueType alchemy font set with key code chart... 

We can express the use of all the different units in evolution in the language of thermodynamics. While the genome is defined by a DNA sequence so that each base has a singular intensive property as in a computer code of symbols, by way of contrast, the protein content of a cell is an extensive property being concentration dependent and therefore varies under circumstances such as temperature and pressure although... 

The recognised body in the United Kingdom for the preparation of specifications for quality, performance or dimensions, methods of test, definitions and symbols, codes of practice, etc. British Standards are prepared under the guidance of representative committees and are widely circulated before they are authorised for publication. BSI co-operates in preparing international standards for rubber and plastics through ISO/TC45 and ISO/TC61 respectively. See ISO. 

This Appendix provides a listing of standards incorporated in this Code by reference, and the names and addresses of the sponsoring organizations. It is not practical to refer to a specific edition of each standard throughout the Code text instead, the reference dates for the specific editions are shown. For ASME codes and standards, specific edition reference dates are not provided rather, the latest published edition in effect at the time this Code is specified is the specific edition referenced by this Code. Subsequent issues and revisions of these referenced standards and any new standards incorporated in the Code by reference in Code Addenda will be listed (after review and acceptance by the Code Committee) in revisions of this Appendix. All identical specifications are indicated by the ASME/originating organization symbols.

For all the structures included, the environmental data by Daams et al. (1991) are given indicating for every atom the corresponding coordination number (CNE) and the polyhedron code. The symbols of the elements at the vertices of this polyhedron are then listed in the order of increasing distances from the central atom. 

Let me make a table to help unravel the codes used for variously substituted tryptamines. First, there can be things that are never considered in alphabetizing, things that are locators of groups, and they always come first in any code. And, the numbers preceed the Greek letters, which preceed the atom symbols, all separated by commas. As examples ...

BASIC. It means Beginner s All-purpose Symbolic Instruction Code and was developed by John Kemeny and Thomas Kurtz (1963). Basic is easy to learn and use. It was mainly designed to be used as an interactive language. Almost every computer manufacturer provides, BASIC on its machines. BASIC is probably the most widely used programming language in the world because of the widespread use of microcomputers.
