Modularized circuit designs for chaotic systems are introduced in this paper. Especially, a typical improved modularized design strategy is proposed and applied to a new hyper-chaotic system circuit implementation. In this paper, the detailed design procedures are described. Multisim simulations and physical experiments are conducted, and the simulation results are compared with Matlab simulation results for different system parameter pairs. These results are consistent with each other and they verify the existence of the hyper-chaotic attractor for this new hyper-chaotic system. © 2015 Chinese Physical Society and IOP Publishing Ltd.

Maintainability is a significant design characteristic of civil aircraft system that has great effect on system availability, life cycle cost and operation safety. A virtual maintenance environment is constructed to support maintainability concurrent design of aircraft system, the evaluation method of maintainability attribute is proposed based on maintenance task virtual simulation or maintainability checklist, and then system maintainability comprehensive evaluation is proposed based on fuzzy theory. A case study, which is maintainability evaluation of a nose landing gear system in civil aircraft, shows the effectiveness of the method presented herein. © 2015 Polish Academy of Sciences Branch Lublin.

Several moving objects detection methods were compared and an improved method on the basis of consecutive frames difference was proposed. Color images captured with camera were transformed into gray ones and the gray ones were processed with median filter. The adjacent frames of any three consecutive ones were handled with differential operation to obtain two difference images and threshold value was set to transform difference images into binary ones. The binary images were dealt with by using opening operation. The location of moving aircraft was determined by performing two difference images with AND operation. The simulation results show that the improved method can effectively detect and locate the moving aircraft in intelligent surveillance system. © (2011) Trans Tech Publications.

A novel approach for OH-PLIF image processing, namely conditioned level-set (CLS) method, is presented in this paper. The complete CLS method consists of raw image pre-processing, adaptive intensity shareholding for linearization, initial contour extraction, region-lock optimization and level set iteration. The successful application of this method to typical molecule diffusion flames demonstrates its robustness to noise sensitivity and flame topology, and its outperformance over traditional edge detectors in terms of flame contour identification. The CLS method provides possibility to further image analysis such as mean reaction zone tracking. Based on the results from RANS simulation with adequate modelling, a novel numerical-aided approach for concentration calibration is also proposed. The CLS method can readily be employed to experimental images obtained from other planar scalar measurements. The proposed method has potential to be integrated to image processing modules of scientific software. © 2015 IEEE.
