This section describes the four frames (structures, symbols, power, and people) in depth.
Table 3 Key questions raised by the four frames Structures Symbols What key structures determine department functioning?
To improve orthogonality, [8] introduces a two-segment structured symbol modulated by different chirp rates and Walsh codes.
Except for the DFT spreading and the structured symbol to subcarrier mapping, it is identical to OFDM [20].
In this structure, transmit symbols are spread in a symbol-by-symbol basis and the self-interference in the receiver is avoided by the use of permutation matrices [21, 22] in the transceiver, which also allow us to decode each transmit symbol separately.
The relation between the replicator (hardware) and the image (a structure of symbols, the software) is a functional relation of dependence, since the symbolic representation consists of directives and instructions that must be interpreted by the replicator machinery for constructing a copy of itself.
AI researchers call the problem of updating, searching, and otherwise manipulating a large structure of symbols in realistic amounts of time the frame problem.
The structure of symbols and operations, by which intellectual solution is performed, as well as searching the strategic reference points for those solutions, which are caused by certain structures of symbols and operations, – are considered among the main issues in analysis of AI and its applications.
First, in order to represent the structure of symbols more clearly and simply, we involve the text entity as one of the basic elements and redefine the relation representation mechanism, which is the foundation for the following algorithms.
Table 2 Relationship between by the basal area increment cm2/year during the 25-year period 1972 to 1997 and the four structure variables (symbols defined previously), expressed by the coefficients of a multiple linear regression, for the ten most common species, represented by at least 50 individuals.
