Abstract: In the software development lifecycle, code static analysis takes an important part in building secure software. To help discover the potential security issues in source code, large numbers of static analysis tools are developed. But the results generated by them display in the form of pure text, so it is time-consuming for developers to analyze these text messages, and it is difficult for developers to concentrate on the most interesting defects in huge data. In this paper, we have developed a visualization system oriented to Java source code, which presents the results in graphics from a developer’s point of view, to help developers to analysis code defects. A novel layout is proposed to visualize software source code in a hierarchy way, which shows the physical structure of the software. A visual overview and powerful interaction is provided in this system which allows the developer to focus on the most pressing defects within huge volumes of source code.

Abstract: Image segmentation is an important task in image analysis and processing. Many of the existing methods for segmenting a multi-component image (satellite or aerial) are very slow and require a priori knowledge of the image that could be difficult to obtain. Furthermore, the success of each of these methods depends on several factors, such as the characteristics of the acquired image, resolution limitations, intensity in-homogeneities and the percentage of imperfections induced by the process of image acquisition. Evolutionary programming(EP) has been applied with success to many numerical and combinatorial optimization problems in recent years. EP has rather slow convergence rates, however, on some function optimization problems. In this paper the new evolutionary programming is proposed to overcome the premature convergence. There are two step mutation in the new evolutionary programming. The first step is responsible for searching the whole space. The second is responsible for searching the local part in detail. The cooperation and specialization between different two step mutation are considered during the algorithm design. The new evolutionary programming can use in image segmentation and the experimental results show the new evolutionary programming is efficient.

Abstract: Illumination consistency makes one of important roles in image authenticity, especially in splicing and copy-move rendering. This paper proposes a new method to estimate illuminant direction based on idea of binary sort tree. The algorithm calculates the least error function to structure the binary tree of illuminant direction. And it doesn’t need to expand much time to solve pathosis equation and access accuracy is improved. The experiment shows that, the algorithm can effectively calculate the light source direction of different objects and backgrounds in an image especially in infinite light source, and the detection correct rate reaches 85.4% in general situation , what’s more, 88.1% in infinite light source. Anyway, the algorithm in this paper is a great advancement of blind forensics based on consistency in lighting direction.

Abstract: As an important creative design mode, the process integration of the collaborative commodity design (CCD) activity is very necessary to be studied deeply. In this paper, the definition of the collaborative commodity design is proposed firstly based on the collaborative design style and the commercial parts applications. Then, the difference between the collaborative commodity design and the collaborative product design is compared. The process integration model of CCD is described. And the three main process integration of CCD are discussed respectively. The integration of the technology scheme restraints to the economic scheme restraints is achieved by these process integrations in the CCD process.

Candidate’s solutions through the population, rather than the probability of vector of save memory and bite string processing. Concise evolutionary algorithm (CEA) is a probability vector based evolutionary algorithm is proposed. This paper proposes a method of realizing the standard FPGA concise evolutionary algorithm with a few changes to improve search powers. A data flow and a block diagram design, this paper describes the show. Experimental results show that the requirements (logical block) need to implement, building processing speed and solution for the power evolvable hardware CEA.

Abstract: Two pulse waveforms are designed and analyzed for 60GHz pulse modulation systems. An indoor frequency selective fading channel model is introduced for single user 60GHz TH-PPM systems. The capacity with this channel model of a 60GHz TH-PPM system based on the designed pulses is derived. Performance results are presented to illustrate the effects of the pulse waveforms and channel properties on the channel capacity.
