A study on the construction method of the orthogonal complementary sets group used for CDMA coding in the sequence analysis, meanwhile, we make the analysis of the relation between complementary Set and the orthogonal complementary Sets group. Furthermore, we design the method which can be used to constitute the orthogonal complementary sets group by the known complementary set, put forward the necessary...
The pulse waveform characteristic point detection is important for non-invasively detecting cardiovascular parameters. A novel designed algorithm based on wavelet transform (WT) is developed. For some pulse waveforms, characteristic points exactly correspond to the zero-crossing of a wavelet with one vanishing moment, while the others incompletely correspond to. And characteristic points also correspond...
In this article, we introduce C-temporal relation data model (C-TRDM), and analyze data redundancy of tradition database and temporal database in existence. For the quantities of temporal database are increasing fleetly, we put forward compress storage tactics for temporal data which combine compress technology in existence in order to settle data redundancy in the course of temporal data storage...
The pumping lemma and Myhill-Nerode is very important in theory of formal languages and automata. In order to depict fuzzy regular language deeply. Firstly, the paper obtains the similar conclusion about fuzzy regular languages and then discusses the closed property under some operations. Finally the notion of commutative fuzzy regular language is introduced, some properties and equivalent depictions...
In this paper, a kind of shape memory alloy (SMA) model based on hysteretic nonlinear theory and data mining was developed and applied in vibration control on rotor system with SMA bearing. Nonlinear difference item was introduced to interpret the hysteretic phenomenon of SMA. Arctangent function was introduced to describe the variation of SMA stiffness with temperature. Based on above, all of possible...
