P-sets consists of an internal P-set XF and an outer P-set XF and has dynamic characteristics, which result from the internal dynamic characteristics on XF and the outer dynamic characteristics on XF. In order to extend the application of the P-sets, the paper proposes an F-recursive binary tree through applying the dynamic characteristics for the P-set XF. Meanwhile, the paper provides the structures...
This paper uses P-sets to give the study of abnormal data in information system. P-sets has dynamic characteristics. The paper adds its attribute conjunction characteristics, namely the spread characteristics of the attribute conjunction and the shrinkage characteristics of the attribute conjunction. And the paper proposes F̄-lost data and F-redundancy data as well as F̄-lost cognizable degree and...
The main purpose of this paper is to study abnormal data whose data elements are increased and decreased simultaneously in data transmission. By using a new mathematic model of P-sets which has dynamic characteristics, this paper proposes the concepts of $$ \bar{F} $$ F ¯ -abnormal data, $$ F $$ F -abnormal data, $$ (\bar{F},F) $$ ( F ¯ , F ) -abnormal data and...
Using P-sets, the concepts of (F, F)-information, (F, F)-search scale and (F, F)-search circle are proposed. Meanwhile, this paper give the search principle of (F, F)-information, the sequence theorem of (F, F)-search scale, the internal-outer point theorem of the unit discrete interval on (F, F)-search scale, and the position theorem of (F, F)-search circle. (F, F)-search circle is a series of concentric...
