A new approach to Chua's circuit is developed in thispaper. OTAs(Operational Transconductance Amplifiers)are used to synthesize it. Firstly, OTAs are utilized forgrounded inductors and piecewise-linear resistors. Then,OTAs are also used for a new variable parameter ofcurrent type Chua's circuit. Moreover, the Lyapunovexponents are calculated. Furthermore, the powerspectrum and the Poincare section are given. Finally,experiments results approve this approach.

Nonlinear optimization is the foundation of multiobjectiveprogramming. In this paper, our focus is augmented Lagrangemultiplier(ALM) method which is employed in constrainednonlinear optimization pwpositions. A dynamic approach israised for minimization subproblem in augmented Lagrangemultiplier method and a neural network alternative algorithm forgeneral constrained programming is proposed.

This paper develops a new technique for manipulatorinverse kinematics at kinematic singularities. The method basedon dropping rank of Jacobian matrix of the transformationbetween the joints rate and end effector Cartesian velocity in thevicinity of singular configurations, and find the solution moreeasily compared with conventional methods. And kinematicsingularities can be included rather than avoided in manipulatormotion planning and control. Examples are given to demonstrateimplementation of the proposed approach.

This paper presents a new systerh called FuzzyFourier system (FFS) for periodic functions mapping. TheFFS composes a set of fuzzy rules in fuzzy Takagi-Sugeno-Kan fuzzy models. We set the consequent of eachnde to be a Fourier series with adjustable parameters(linear combination of orthogonal cosine functions).Therefore, the input/output mapping of FFS is periodic. Inaddition, with minor revised, The FFS can be used to be adigital-filter for given magnitude *** examples illustrate the effectiveness of ourapproach.

In the paper, it is introduced a group digitalsignature scheme. The scheme is aimed at electroniccheckup, proofreading, cosigning and etc. fore-cooperative work in engineering design, which isbased on Schnorr protocol. It is solved the securityproblem in the process of e-cooperative work. It isdesigned that the scheme includes the group disitalsignature and verification in sequence and at one timefor the characteristic of e-cooperative work. It is alsoanalyzed the safety and anti-attack of the scheme.

ITLC(The Intelligence Traffic Light Controller) isconsideed busy time on the road when peoples go to workplace and ligh time about traffic. Traffic congestion increasebecause of current traffic ligh allocates as most fixed *** can be reduced waste time from drivers on the road. Inthis paper, Traffic lights of main roads are applied fixed timeand narrw roads are applied autonomously by sensor. ITLC'sefficiency is increased when vehicles are less to the narrowroad. In experimental result, we got an efficiency of this ITLCthat is maximum 36%.

In many color image processing, edge detection is a useful method for obtaining a simplified image that preserves thedomain geometric structures and spatial relationships. For providing accuracy edge, we propose an isotropic color edge detectiontechnique. A fast entropy threshold technique is also developed for reducing the computation burden. Experimental results haveconfirmed that this technique is very efficient.
