A new product conceptual design approach is put forward based on Hopfield neural networks models. By research on the mechanisms of Hopfield neural networks, the associative simulation approaches are proposed. The approach is given by Hebb learn- ing law, Hopfield neural networks and crossover and mutation. The calculating models and the calculating formulas for the concep- tual design are put forward. Finally, an example for the conceptual design of a solar energy lamp is given. The better results are ob- tained in the conceptual design.

The β decay of Cd129, produced in the relativistic fission of a U238 beam, was experimentally studied at the RIBF facility at the RIKEN Nishina Center. From the γ radiation emitted after the β decays, a level scheme of In129 was established comprising 31 excited states and 69 γ-ray transitions. The experimentally determined level energies are compared to state-of-the-art shell-model calculations. The half-lives of the two β-decaying states in Cd129 were deduced and the β feeding to excited states in In129 were analyzed. It is found that, as in most cases in the Z<50, N≤82 region, both decays are dominated by the ν0g7/2→π0g9/2 Gamow–Teller transition, although the contribution of first-forbidden transitions cannot be neglected.

2013 2nd International Conference on key engineering Materials and Computer Science(KEMCS 2013)

作者： QIAO Shan Ping YAN Bao Qiang School of Management Science and Engineering Shandong Normal University Shandong Provincial Key Laboratory of Network Based Intelligent Computing School of Information Science and Engineering University of Jinan School of Mathematical Science Shandong Normal University

Genetic algorithm is a very important and popular kind of algorithm of evolution computing. In order to use this algorithm better and platform-independently, this paper introduces an implement package which is coded in Java, an object-oriented and platform-independent advanced computer programming language, for genetic algorithm. This package includes several sub-packages. In each sub-package, there are some classes with different roles and functions. After the test, these classes can work properly and efficiently in together. The good effect has been received through using this algorithm in four function optimization problems. For the further goal, some studies even need to be carried out in the future.

IEEE International Conference on engineering of Complex Computer Systems

作者： Xiaofeng Wu J.W. Sanders Huibiao Zhu East China Normal University Shanghai CN African Institute for Mathematical Sciences South Africa Shanghai Key Laboratory of Trustworthy Computing Software Engineering Institute East China Normal University Shanghai China

Wireless systems have a wide range of applications recently. To explore complex features of such systems, formalisms are proposed to specify and reason about them. This paper presents a case study of routing protocol in wireless networks. We formalize the route discovery process of AODV routing protocol using Object-Z. Network topology and local variables of nodes are defined by relations and functions. The broadcast communication is modelled by operations which change local variables of the sender and all of its connected receivers simultaneously. We show the proof of loop freedom property for established routes based on the specification. Further, the specification is modified by adding mobility of nodes and loop freedom under a dynamic network topology is discussed, showing the scalability of our approach.

IEEE/SICE International Symposium on System Integration

作者： He Jiang Min Hu Hongbo Chen Kun Li Xiaohua Wang Fuji Ren School of Computer and Information Affective Computing and Advanced Intelligent Machines AnHui Key Laboratory Hefei China Fellow of the Japan Federation of Engineering Societies University of Tokushima Shinkura-cho Tokushima Japan

Image description is not sufficient in traditional facial expression recognition (FER) methods, therefore this paper proposes a FER method based on multi-scale vector triangle. It combines vector triangle pattern with image pyramid to extract facial expression features. Firstly, construct a facial image pyramid to produce images in different scales. Secondly, divide each image into blocks, and extract vector triangle features of each sub-image. Then, use histogram to statistical characteristics, and calculate Euclidean distance between the histograms. Finally, fusion weighted eigenvalues and come to the recognition results. Multi-scale vector triangle pattern can not only avoid the loss of information in image asymmetric regions, but also reflect image features in different scales. It can describe images more adequately. In order to verify the effectiveness of the algorithm, this paper uses the Japanese Female Facial Expression (JAFFE) database to do the experiments and compare the results with Complete Local Binary Patterns (CLBP), Gabor wavelet, Active Appearance Models (AAM) and so on. Experimental results indicate that this method has higher recognition rate and better real-time effect.

IEEE/SICE International Symposium on System Integration

作者： Ning Liu Fuji Ren Xiao Sun Changqin Quan AnHui Province Key Laboratory of Affective Computing and Advanced Intelligent Machine HeFei University of Technology HeFei China P.R. The Japan Federation of Engineering Societies University of Tokushima Shinkura-cho Tokushima Japan

Since Sina microblogging was first launched in August 2009, that seems to have become the major social media communication platform in China, microblogging is increasingly deep into life. In this study, we analyze the sentiment of microbloging hot events based on Ren-CECps. According to hot events in chronological, choosing the microblogging hot events of “Beijing Heavy Fog” and “Xi Jinping, Peng Liyuan Visit” for instance, crawling through sina microblogging we can get the corpus that contains the specified events. The method uses word frequency statistics for access microblogging corpus, analyzing trends in specific keywords concerns. At the same time, according to specific keywords related to micro-Bo, we can calculate the emotions of related microblogging via Ren-CECps. Finally, according to changes from time to time, we make a corresponding data charts, visual display of such trends. In this study, we illustrate that we can get a good result of emotion analysis using Ren-CECps in such a microblogging Chinese text with fragmentation and discrete feature. As a further indication of such excellent Chinese emotion corpus, the practical and research value in it are enormous.
