Abstract: The chaotic system has many excellent characteristics, such as the sensitivity to initial conditions, the randomness of the class, the non-predictability, and so on, which can be confused with the principle of code design. As one of the most important characteristics of chaotic systems, it is also one of the most important characteristics of chaotic systems. The chaotic system is applied to chaotic secure communication. In particular, it is important to generate the test, analysis and related system of the secure communication system. The establishment of cell model of chaotic attractor and periodic orbit theory further deepen the understanding of the chaos mechanism. It also gives a new idea for the study of the chaos mechanism, which provides theoretical basis for the practical engineering application. In the present study, the method of generating chaotic sequences of secure communication can be divided into two categories, namely, chaotic signal and chaotic signal. Chaotic signal is used in digital computer. Most of the theoretical studies are based on the algorithm, which is characterized by the replication, the noise and the sensitivity to the initial state. Physical chaos is the actual chaotic circuit or chaotic system, which is realized by the specific hardware circuit. Physical chaos is considered to be a chaotic system with unpredictable nature. It is a key to the application of chaotic system in secure communication. This paper attempts to build a secure communication hardware platform with unpredictable physical chaos.

Rong Wang

College of Comparative Law, China University of Political Science and Law, China

Page No: 285-296

Abstract: As the imperfect of China's legal system for the bill discounting, there are still several problems in aspects of the bill discounting, such as single category of bill discounting, less participated subjects and fictional trading background, which have significantly influenced the development of the bill discounting business in a healthy way. In recognition of the legal nature, the bill discounting refers to bill transaction, which is the embodiment of bill negotiability. However, the existent China's Law of Bill denies the no-cause character of bill business, which does not meet the need of generally commercial practice as well as deviates from the legal attribute of negotiable bills. On the basis of the recognition for the no-cause character of bill business, the financial bills should be legalized. In accordance with the legal logic of bill discounting, China's Law of Bill should improve the relevant rules and regulations for bill discounting as well as recognize the no-cause character of bill business during the process of revisions in the future, and the legitimate status of financial bills should also be recognized on this basis.

Keywords: bill discounting, the legal nature, financial bills, the no-cause character

Ph.D. Candidate, Faculty of International Law, China University of Political Science and Law, Beijing, China

Page No: 334-349

Abstract: Due to the adjudication of a large range of regulatory measures under investor-state arbitration (ISA), the belief that bilateral investment treaties (BITs) fail to balance investment protection with a host country's right to regulate has gained currency as of late. In order to balance investment protection with regulation, many scholars have advocated for the use of public law principle of proportionality to interpret BITs. This paper critically examines the application of the principle of proportionality in BITs under two heads. First, analyzed the application of principle of proportionality in ISA cases, given the attitude of the different tribunals toward the issue; second, given deep discussion in proportionality principle in BITs and found out that when interpreting BITs, application of principle of proportionality in many instances will completely ignore the clear textual language and thus violate the rules of treaty interpretation.

School of Electronic and Information Engineering, Changchun University of Science and Technology, Changchun, 130022, China

Page No: 374-379

Abstract: Confocal scanning laser ophthalmoscope based on adaptive optics can correct the aberrations, which can achieve high resolution imaging in vivo retinal. But because of the micro tremor of the patient and the jitter of the device, the video image of the adaptive optics scanning laser ophthalmoscopy (AOSLO) output is blurred. To solve this problem, an AOSLO image stabilization algorithm based on gray projection is proposed. Firstly, histogram equalization is used to preprocess the original video image, and the motion vector is obtained by the row-column projection searching for matching areas method, then cross correlation algorithm is used as the matching measure to correct the error of motion vector, finally the fixed frame compensation method is used as motion compensation to realize video stabilization. Experimental results show that the proposed image stabilization algorithm can effectively remove the blur and enhance the contrast of the video images.
