Page No: 254-262
Abstract: This paper, location model of public bicycle rental station is established by the intelligent ant colony algorithm. Every ant agent leaves pheromone step by step in the search path, so that it can solve the problem of the optimal location through the guidance of the pheromone. The calculation result shows that too much or too little ants will both affect the searching ability of the algorithm. However, the selection method of the ants’ number in different models needs further discussion.

Page No: 263-271
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. Above research has important theoretical significance and application prospect for the development of chaos theory. First of all, this paper introduces the relevant knowledge of chaos and cryptography and prediction of related basic theory, and then conducted a major research in the following aspects: Based on the periodic orbit theory of chaos simulation analysis of issues related to the discussion, with the prediction of physical chaotic random sequence and randomly generated statistical test analysis, based on Chua's circuit s box design and analysis, a new synchronization scheme based on physical chaos secure communication system.

Abstract: According to computer crime and Security Research Report in 2002, the computer and the hard drive stolen data on the hard drive has become the second major security issues that people care about following the computer virus infection. The basic security technology to protect the data confidentiality of hard disk is hard disk data encryption, but the use of software encryption has the problem of reducing the system performance and its own security. Therefore, it is very important to study the hardware data encryption system based on modern encryption technology. At present, many foreign companies and institutions on the hard disk data encryption research, has also developed a number of commercial products and encryption chip, but the domestic research compared with foreign countries have a larger gap. Combining with the modern basic knowledge of cryptography and the FPGA technology, developed a line of hard disk based on DES algorithm encryption card. The main work includes: 1) Hard disk operating mechanism and ATA standard; 2) FPGA design technology research; 3) Basic research of modern cryptography; 4) On line type hard disk encryption card; 5) Discussion on key management scheme.

On the Predicament, Logic and Perfection of China's Bill Discounting System
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.

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.

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.

Page No: 388-394
Abstract: Background prediction method is one of the major methods for suppressing the background in infrared dim small target detection. In this paper, an algorithm based on local homogeneous background prediction is proposed, on the basis of the analysis of the gray feature model of different background components on sky background, edge detection is carried out and the image is divided into different regions including different gray nature, the results of edge detection are used to modulate prediction weight matrix, then the convolution operation is performed between the original image and the different region prediction weight matrices to obtain the different region prediction images which are summed to obtain prediction image. Residual image is obtained from the difference between the original image and the predicted image. Simulation results show that the proposed algorithm can effectively preserve the details and reduce the negative impact on the prediction from the pixel gray level in heterogeneous region, and significantly improve the detection performance of small targets in low SNR conditions.
