Retraction: Aydin, B. Statistical Convergent Topological Sequence Entropy Maps of the Circle. Entropy 2004, 6, 257–261

Abstract

The editors were made aware that a paper published in Entropy in 2004 [1] may have plagiarized an earlier paper by Roman Hric published in 2000 [2]. After checking with specialized plagiarism software, we found that this claim is indeed correct and almost the entire paper is a verbatim copy of the earlier one. After confirmation of this fact, the editors of Entropy have decided to retract the paper immediately. [...]

Double Entropy Joint Distribution Function and Its Application in Calculation of Design Wave Height

“…The double entropy probability density function of wave height and period can be obtained after substituting Equations (10) and (18) into the following equation, which is:…”

“…The marginal distributions of wave heights and periods are selected and adopted as shown in Equations (11) and 12, respectively. The corresponding parameters can be obtained through Equations (7) and (18), as shown in Table 1. The maximum entropy probability density functions of wave height and period are respectively obtained by substituting the parameters of Table 1 into Equation (19) and are as follows:…”

“…In view of general applicability of the maximum entropy distribution, it can constrain the existing data while maintaining the greatest uncertainty for the unknown information, so that the priori and artificial nature of the traditional methods can be avoided to a certain extent. Currently, the maximum entropy principle has been extensive applied to many fields [18][19][20].…”
