Intuition process is a very essential in the product creative design stage. A new creative design approach is put forward based on product gene and intuition models. The product gene model and its sequential gene manipulation are established. The intuition process reflects that the thinking of human brain produces qualitative change. An approach of intuition simulation is used by Hebb learning law, Hopfield neural networks and crossover and mutation. The calculating models and the calculating formulas for the creative design are put forward. Finally, this essay offers us the applied examples for creative design of solar energy portable lamp. The better results are obtained in the creative design. ©2010 IEEE.

Image encryption is one of the most important methods of image information hiding. A new image encryption method based on dual DNA sequences for image hiding is presented in this paper. This method is implemented by using the natural DNA sequence and the chaotic initial value as keys and the chaotic map as main tool to fully exert the special advantages. Firstly, the DNA sequence is used to express the original image has been confused and key DNA sequence are calculated in light of the given definition. Then, the new DNA sequence is confused based on the chaotic sequence is generated by Logistic Mapping. The experimental results and analysis demonstrates that the image encryption algorithm is feasible and highly secure. Moreover, the size of the encrypted image is the same as the original image so that it can be applied for image hiding and be transmitted via the Internet. ICIC International © 2010 ISSN 1881-803X.

In order to enhance the image information security, image encryption becomes an important research direction. A new image encryption algorithm based on encryption template is presented in this paper. This algorithm is implemented by using the natural DNA sequences as main keys and the new defined encryption template as main tool to fully exert the special advantages. Firstly, the original image is confused in the light of the chaotic sequence is generated by Logistic Mapping. Secondly, the encryption template is generated by the new given definition in which DNA sequences and chaos game representation are used.

In order to protect image effectively, presented an image encryption algorithm based on wavelet function and four-dimension chaotic system. The algorithm firstly uses Wavelet function chaotic maps to scramble the image pixel location, and then use four-dimension chaotic system disturbs image pixel value. Experimental results show that the algorithm has a good properties that Shannon proposes confusion and diffusion. At the same time, It can resist a strong attack with the large key space, encryption image pixel values has a random uniform distribution and adjacent pixels value has zero correlation. These results show that the proposed scheme has good security characteristics.

With the fast development of Internet technology and information processing technology, the image is commonly transmitted via the Internet. People enjoy the convenience and shortcut, but people have to face to the obsession that the important image information in transmission is easily intercepted by unknown persons or hackers. In order to enhance the image information security, image encryption becomes an important research direction. An image encryption algorithm based on DNA sequences for the big image is presented in this paper. The main purpose of this algorithm is to reduce the big image encryption time. This algorithm is implemented by using the natural DNA sequences as main keys. The first part is the process of pixel scrambling. The original image is confused in the light of the scrambling sequence is generated by the DNA sequence. The second part is the process of pixel replacement. The pixel gray values of the new image and the one of the three encryption templates are generated by the other DNA sequence are XORed bit-by-bit in turn. The experimental result demonstrates that the image encryption algorithm is feasible and simple. Through performance analysis, this algorithm is robust against all kinds of attacks and owns higher security.

DNA self-assembly that is fast developed in the fields of DNA computing and nano technology has become the focus of scientific fields. DNA self-assembly is a method that uses the characteristics of base-pair to form polyhedron or super molecular structure. This is a complex progress from disordered to ***, from simple to complicated. This paper mainly introduces that the DNA self-assembly technology is applied into the image encryption. In this paper, we proposed a complete design scheme of DNA tiles that is suitable for the image encryption. The DNA tiles mainly include five types, namely DNA tiles of the plaintext, DNA tiles of the encryption, DNA tiles of the cipertext, DNA tiles of the key and DNA tiles of the decryption. Through a simulate example, the effect of the image encryption algorithm is shown.

In the system of the PV grid-connected generation, because of the dispersion of the PV panel, difference of the sun radiation condition and the shadow of a part of the PV panel, they will cause the serious loss of energy for the parallel PV panel. In order to overcoming energy loss and raise the efficiency of the PV system, a new maximum power point tracking method called distributed variable step duty ratio perturb method is put forward. The distributed MPPT method overcomes the shortcomings to generate electricity quantity to descend because of the dispersion of the PV panel. The variable step duty ratio perturbing method speed quickly and is more suitable for this kind of distributed generation system. The hardware adopts DC/DC electric circuit to regulate PWM duty ratio. The software adopts TMS320-2812. An example is given to show that this method is able to realize distributed MPPT. In addition, the calculation speed of the approach is quick, accuracy of the approach is better, and the system has a high stability. © 2010 IEEE.
