M2M pose unique security challenges as the automation and lack of human intervention makes the network vulnerable to a variety of potential attacks and inadaptable to current situation where conventional security solutions are infeasible. Our framework comprises of security components which achieve certain level of security that enables the M2M systems to interface with intelligent devices that are deployed in customer facilities to sense real-world conditions and control physical devices, relay data from the devices in the customer premises to a centralized data center, and analyze the data and trigger business events. We also present performance results of our framework and show that our framework is capable of scalably and reliably handling concurrent events generated by different types of M2M devices, such as RFID tags. Zigbee sensors, and location tracking tags to achieve a high degree of security.

A novel image segmentation method is proposed using geometric active contour model based on an adaptive bidirectional balloon force (ABBF). Since active contour model was used extensively in image segmentation. great progress has been achieved. The evolved active contour model combined with balloon force could effectively detect object boundaries, however, this model require that we must put the initial active contour inside or outside the boundary completely, also it is easy to cause leaking through weak edges. In order to solve these problems, we propose a new ABBF-snake model based on magetostatic field. According to our experiment, it is obvious that our method make great improvement in convergence ability and broken edges, furthermore. compare with GVF and VCF, our method achieved more satisfactory results in segmentation of complex shape objects and real images.

Based on the principle of binocular parallax, this paper designs a simple. practical. fast and convenient passive real-time video monitoring ranging system. The system realizes the real-time video monitoring ranging algorithm of the system and analyzes the accuracy and the error of the ranging system. By doing experiments, the algorithm turns out to be of simple ranging method, good real-time and stability, high accuracy and simple equipments. Another advantage: the system doesn't send signals while working. so it is convenient to conceal yourself, thus having a high safety. Therefore, the system has great application values in the fields like air defense for strategic points, land and sea defense monitoring, real-time monitoring of the battlefield, etc.

To promote the efficiency of English pronunciation training, the Computer-Assisted Pronunciation Training (CAPT) system is drawing more and more attention of language teaching, but the current CAPT systems for Chinese second language learners are still quite dissatisfactory. The paper briefly introduces the CAPT technology and its realizing process, and discusses the application of visual speech synthesis technology in CAPT to enhance its friendliness in detail. Comparable teaching experiment demonstrates that the CAPT system improved by visual speech synthesis can significantly improve the efficiency of English pronunciation training.

The goal of this paper is to investigate the threshold cointegration effect of financial deepening on economic growth in Taiwan over the period from 1981 to 2010. The results show that a threshold cointegration effect exists in relationship between financial deepening and economic growth. In short-run, economic growth has a significant and positive effect on financial deepening in the high-growth regime. This implies that economic growth can stimulate financial deepening in Taiwan in the high-growth regime. In addition, the impact of financial deepening on economic development has a significant and positive effect in the high- and low- growth regimes. Thus, financial deepening can increase economic growth in Taiwan.

Education of ideal faith is an essential part of ideological and political education for college students. It appears new characters and problems under the new historical conditions. Taking 528 college freshmen as an example to investigate and analyze ideal faith of contemporary college students in the new period. The result shows that in general the ideal faith of college students is good, but there are some problems with distinctive characteristics of times which should not be ignored. Ideal belief education for college students should be closely related to the reality of their lifestyle and thoughts. Pedagogue should follow the law of formation governing ideal belief, should be integrated into the process of college students' self-development, and should tend to deal with their problems as well. Realization of the social ideal, long-term ideal and lofty ideal should be integrated into the college students' individual ideal, short-term ideal and general ideal.

This paper proposes a new resolution reduction method for halftone images. Recently, smartphone or tablet PC has become widespread. When viewing comics on mobile devices as e-books, image resolution conversion is required, because there are various resolution devices. If comic images are reduced with conventional resolution conversion methods using interpolating functions such as bicubic interpolation, moire which leads to deterioration in image quality is generated, because comic images include halftones with periodic structures. In this paper, we propose a resolution reduction method for halftone images which preserve periodic structures of original images. Experiments show that a moire is not generated with our proposed method, and the method is superior in subjective image quality and computational time to the conventional bicubic interpolation.
