It is difficult to compute large RNA molecules with pseudoknots in bioinformatics, the prediction of RNA structure with pseudoknots is an NP-hard problem. According to PTAS principle and MFE models, we investigate the RNA pseudoknotted structure. We first presents an efficient algorithm for predicting RNA structure with pseudoknots. The experimental tests in PseudoBases indicate that the algorithm...
Identification the accurate model is crucial and initial step for applying advanced process control. A hybrid system identification method is proposed in this paper. This combination algorithm is designed to take both advantage of differential evolution (DE) and new Luss-Jaakola (NLJ) algorithm, which use the DE to search the initial parameters for the NLJ algorithm. The results of simulation have...
A new IMC-PID tuning method based on combination algorithm of DE and NLJ is proposed in this paper. The IMC-PID controller tuning strategy which is on the basis of internal model control, not only keeps the characteristic of conventional PID controller, but also has the advantages of internal model control. The simulation shows that using this method to tuning PID parameters has good control performance...
