PdPc was synthesized with Phthalonitrile and p-Cresol as the source material of benzene ring by the template synthesis method of two steps reaction. Through doping with perchloric acid, vitriol and nitric acid, semi conducting doped PANI was obtained. By means of molecular hybrid modification, PdPc and doped PANI was polymerized and formed a kind of new organic semiconductor material PdPcxPANI1-x. The combination of chip and new sensitive material was achieved by virtue of vacuum metallizing. PdPcxPANI1-x which was hybrid synthesized by FT-IR and SEM was a new kind of material. The film morp hology and crystalline phas were characterized through SEM, and it showed that when the evaporation coating temperature was about 350°C∼650°C, the surface of film emerged a kind of deposition growth partical which was like tooth. The diameter of the particle is 200nm, very homogeneous and its aperture is ordered. In order to measure gas sensitivity of CuPcxPANI1-x thin films, a sealed test box was used. The results indicate: organic gas sensitive materials PdPc0.15PANI0.85 doped with vitriol acid has good gas sensitve property to SO2, PdPc0.5PANI 0.5 doped with nitric acid has good gas sensitive property to NO 2, PdPc0.35PANI0.65 doped with perchloric acid has good gas sensitive property to Cl2. When vH is 2.0V, output resistance keeps within 5% and sensitivity keeps within 7.5% in six months. © 2011 IEEE.

The detection of milk proteins can be achieved by light scattering. But in the process of detection, there are many influences that directly affected the accuracy of detection. On the basis of researching the light scattering characteristic of milk proteins, we have studied the effect of physical-chemical conditions such as scattering angle and temperature on scattering light intensity. Through simulation experiments, we can find that parameters such as scattering angle and temperature also have directly impact to the casein micelle detection. According to the simulation result, the detection parameter has been optimized, the theoretical support and guidance for increase the detection accuracy also has been provided.

The objectives of this study were to investigate the measurement methodology of the protein content in skimmed milk by laser light scattering(LLS). There was a definition that the ratio of the scattering light( at 90° scattering angles, relative to the incident beam direction) intensity to the transmitted light intensity, which was called scattered transmitted ratio(STR). Using the STR theory, we constructed a sensing system to measure the protein content. The sensing system contains a laser beam of 658 nm wavelength, sample reservoir and two photodiodes which measure the scattered light and transmitted light respectively. Through data analysis, the relationship model was established between the protein content and the STR. Comparing with Kjeldahl determination of nitrogen, the STR method described in this study can also accurately measure the protein content.

On the basis of these, we studies the reflective spectrum of soil moisture and evaluates primarily the repeatability and stability of the system in the practical measuring. The testing results show that the system has good qualities of stability and easy operation. © 2011 IEEE.

The Reconstruction for disparity image is the key technology for 3D image restoration in stereovision field. However, the data volume of disparity images is so large and the topological structures of disparity images is so complicated that reconstruction for disparity image is very difficult. We had done a lot of works for the sake of constructing a new method to reconstruct disparity image. In this study, a reconstruction method for disparity image based on region segmentation and isomorphic RBF(Radical Basis Function) neural network is presented. First, the disparity image is divided into some regions with adjustable threshold and edge detection. Next, reconstruction based on RBF neural network is carried out in every region, in which process the disparity point clouds are optimized. Then, all the regions are connected and the reconstruction result is obtained. When reconstruction based on RBF is executed in different regions, trainings are carried on with different resolution data according to the complexity of the structures of different regions. Experimental results show that the method proposed in this study can attain reconstruction results of high quality effectively. © 2011 Asian Network for Scientific Information.

In multi-agent systems, agents are inclined to form coalitions to improve individual performance and perform tasks more efficiently. However, the most existing researches assume that the desired outcome is a coalition structure that consists of disjoint coalitions where every agent that has joined a coalition is no longer available to join other coalitions, which leads to waste of resources. In a number of practical scenarios an agent may have to be involved in executing more than one task simultaneously, and distributing its resources to several completely different coalitions. To tackle such problems, we propose the concurrent formation of overlapping coalitions and introduce a two-dimensional binary encoding to search the coalition space. We mainly focus on the revision algorithm for invalid encodings. Specifically, by using the proposed revision algorithm, an agent may join in several different coalitions at the same time without any resource conflict. Moreover, we prove by mathematical induction that the proposed algorithm will not discard any invalid encoding and can revise any invalid encoding into a valid one. Finally, a contrast experiment is illustrated to demonstrate the proposed algorithm. © 2010 Elsevier B.V. All rights reserved.
