Quickly recovering and securing the advanced vehicle performance by changing structures, upgrading equipment become a key point to win the modern war. The armored vehicle is a complicated coupling system and the structure components are closely connected. Thus the change design is a complicated coupling system design problem. We provide the-state-of-art of the change design in response to environmental changes, and discuss the key technologies of armored vehicle adaptive change design responding to complex environment (AVACDCE). We also discuss design strategies and principles, change design decision and environmental adaptability evaluation, structural conflict elimination, performance optimization and layout optimization design in the limited space, and interface and assembly. In additional, we provide the design flow of the AVACDCE. Our studies can provide support for the armored vehicle adaptive change design responding to the complicated environment. © (2014) Trans Tech Publications, Switzerland.

Network motifs are overly represented as topological patterns that occur more often in a given network than in random networks, and take on some certain functions in practical biological applications. Existing methods of detecting network motifs have focused on computational efficiency. However, detecting network motifs also presents huge challenges in computational and spatial complexity. In this paper, we provide a new approach for mining network motifs. First, all sub-graphs can be enumerated by adding edges and nodes progressively, using the backtracking method based on the associated matrix. Then, the associated matrix is standardized and the isomorphism sub-graphs are marked uniquely in combination with symmetric ter-nary, which can simulate the elements (−1,0,1) in the associated matrix. Taking advantage of the combination of the associated matrix and the backtracking method, our method reduces the complexity of enumerating sub-graphs, providing a more efficient solution for motif mining. From the results obtained, our method has shown higher speed and more extensive applicability than other similar methods. © the authors, publisher and licensee Libertas Academica Limited.

In this paper, an algorithm that embed watermarking into archive image based on image normalization and PCA is proposed, which is based on image normalization and invariant centroid theory. For the purpose of enhancing the invisibility and resistance to geometric attack of watermarking, we first encrypt the watermarking with chaotic method before information embedding, and then eliminate the effect of geometric change to archive image by utilizing image normalization. Finally, PCA was applied to embed the watermarking in subspace. Corresponding, we perform inverse transform to the archive image which is attacked by geometric transformation before extracting the watermarking. Thus, we can prove the truth of the attacked archive image by the extracted watermarking which is recognizable. Copyright © 2014 American Scientific Publishers All rights reserved.

Influenza is an acute respiratory illness that occurs every year. Detection of Influenza in its earliest stage would reduce the spread of the illness. Sina microblog is a popular microblogging service, provides perfect sources for flu detection due to its real-time nature and large number of users. In this paper we investigate the real-time flu detection problem and describe a Flu model with emotion factors and sematic information (em-flu model). Experimental results show the robustness and effectiveness of our method and we are hopeful that it would help health organizations in identifying flu outbreak and take timely actions to control. © 2014 Proceedings of the Conference - 5th Workshop on South and Southeast Asian NLP, WSSANLP 2014 - co-located with the 25th International Conference on Computational Linguistics, COLING 2014.

In this paper, we present a new image preprocessing method which is based on Wavelet Transform. Before we extract expression texture information, Wavelet transform will be applied to remove partial high frequency information. And then Gabor Transform will be used to extract expression information. At last we chose the Support Vector Machine to classify facial expressions. Experiments on the Japanese Female Facial Expression (JAFFE) Database illustrate that the Wavelet Transform and Gabor features are effective for facial expression discrimination. Additionally, the experiment results validate the feasibility of this method. © 2014 IEEE.

As we all know, rigid structure is the universal form of robots. They can be controlled accurately, but are not suitable enough for applying in rehabilitation, especially for hands. Human's hands have some complicated patterns of movement and narrow joint range of motion, so rigid accessory equipment may cause secondary injury. For the purpose of avoiding this potential risk, the idea of applying soft structure to hand rehabilitation robot is presented in this paper. The soft robot is a new research direction in the field of robot industry, especially in rehabilitation. The soft actuator we presented is made of liquid silicone and thread, and can be tied to the back of human's hands. When it is inflated or deflated, a bending and stretching motion of hands follow with the deformation of soft actuators. It works by deforming repeatedly. The soft actuator has some advantages such as portable, lightweight, low-cost, safe, low-impedance and so on. It works well by the cooperation of vacuum pump which can provide incessant air and solenoid valve which is used for reversing. In the whole system, force sensing resistor and bending sensor are used in the experiments. In order to prove that the soft actuator can work smoothly, we had a test to explore the relationship between air inflow and bending angle. The result that their relationship is close to a straight line means controlling easily and working well. Beacons of these advantages the soft robots have, a wide application prospect in rehabilitation or other fields is available.

A novel and fast chaotic cryptosystem for image encryption

引用

Journal of Computational and Theoretical Nanoscience 2014年第3期11卷 731-738页

In recent years, there has been growing interesting in image encryption based on chaotic systems. In order to improve the effect of encryption, a large amount of operations are implemented in the most chaos-based cryptosystems. However, the runtime of chaos-based cryptosystems would be increased with the rise of operations. In this paper, a novel algorithm is proposed to generate cipher key for the permutation-diffusion architecture. The cipher key not only relates to the plain-image, but also the generated time of cipher key is shorter than the conventional method. On the premise of security, a novel and fast permutation-diffusion architecture based on chaotic systems and variable control conditions is proposed. For the sake of increasing the key space and enhancing the security of proposed architecture, variable control conditions used in this cryptosystem as the parameter and initial value of same chaotic system are generated from the cipher key related to the plain-image. So the proposed algorithm can effectively resist the most attacks against permutation-diffusion architectures. Finally, theoretical analyses and numerical experimental results show that the proposed chaos-based cryptosystem possesses high security and sound time of image encryption, which is suitable for protecting the image information Copyright © 2014 American Scientific Publishers.

We herein simulate the scheduling process of automatic guided vehicle (AGV for short) with Plant Simulation, and try to obtain an optimal configuration for meeting practical engineering requirement in one assembly plant. We defined the predetermined loading station, unloading station and walking path simulation, and obtain a specific simulation time. Then, we build AGV simulation model, import data, define procedures and run the simulation process. By running the model repeatedly, we obtained the cost time and utilization rate of AGVs in each group in the process, and compared the simulation time to obtain the appropriate number of AGVs. The machine utilization results verified our simulated AGV configuration. © (2014) Trans Tech Publications, Switzerland.

With the development of integrated circuit manufacturing technology, low power test has become a focus of concern during testing fields. This paper proposes a new low power BIST (built-in self test) scheme based on block encoding which first exploit a block re-encoding method to optimize the test cube, and then a low power test based on LFSR (linear feedback shift register) reseeding is applied. According to the compatibility of flag, the scheme proposes a grouping algorithm based on flag to divide and reorder the test cubes in the test cube set. Experimental results show that the scheme not only obtain better test compression ratio and test data storage, but also reduce the test power consumption effectively. © 2014 IEEE.
