In the paper an application of selected agent-based evolutionary computing systems, such as flock-based multi agent system (FLOCK) and evolutionary multi-agent system (EMAS), to the problem of continuous optimisation is presented. Hybridising of agent-based paradigm with evolutionary computation brings a new quality to the meta-heuristic field, easily enhancing individuals with possibilities of perception, interaction with other individuals (agents), adaptation of the search parameters, etc. The experimental examination of selected benchmarks allows to gather the observation regarding the overall efficiency of the systems in comparison to the classical genetic algorithm(as defined by Michalewicz) and memetic versions of all the systems.

We present a comprehensive evaluation of the influence of "harmonic" and rhythmic sections contained in an audio file on automatic music genre classification. The study is performed using the ISMIS database composed of music files, which are represented by vectors of acoustic parameters describing low-level music features. Non-negative Matrix Factorization serves for blind separation of instrument components. Rhythmic components are identified and separated from the rest of the audio signals. Using such separated streams, it is possible to obtain information on the influence of rhythmic and harmonic components on music genre recognition. Further, the "original" audio feature vectors stemming from the non-separated signal are extended with such that base exclusively on drum and harmonic sections. The impact of these new parameters on music genre classification is investigated comparing the "basic" k-Nearest Neighbor classifier and Support Vector Machines.

The hospital health economy management mainly take is appraised the object the economic efficiency as the core goal, but regarding the hygienic economy management most core health resources disposition management, medical and health organization economy contents and so on management target and method has not involved nearly completely. Changes the work based on the national new medicine for the background medical department Chongqing four experiment site project, analyzes the new medicine to change the economical management question which under the background various medical and health organization faces, proposed one based on the Chongqing region health information platform hygienic economy management frame. The expectation through this article research, can promote our country's hygienic economy supervisory work, makes a contribution for our country's medicine health organizational reform.

This paper depicted the development of IT outsourcing at present, which proposes to utilize four different kind of change mode to IT outsourcing enterprise process including product developing process, service deliver process and so on. By analysis the case of IT outsourcing enterprise process. four key factors are found which affect on type of change mode during the different period of IT outsourcing enterprise developing. IT outsourcing enterprise process will increase changes, which requests IT outsourcing enterprise continuously to adjust and adopt new methods to manage business process.

In this paper, current methods about perceptual hashing were deeply researched and the defects of them were analyzed. Principles and characters of discrete cosine transform, Watson visual model and chaotic model were introduced in details. A new method about perceptual image hashing which combined the characteristics of the three models was designed. This method use discrete cosine transform to feature extraction from image, eigenvector was handled by contrast sensitivity table, Logistic equation was used as chaos sequence generator to encrypt and at last the prediction differential method was used to quantization coding. Experimental results indicated that the method could resist the content-preserving modifications, and possessed strong robustness, safety and retrieval ability, and the collision rate decreases to level 10(-7). Therefore, this technique has the applied value in image authentication, copyright protection, image security and content-based image retrieval and so on.

In the pervasive computing environment, humans and devices or machines with computing ability become interoperable. In order to implement intelligent services in this environment, hardware technologies such as sensing and security are needed. However, the development of technology that enables devices to take contexts into account is also necessary. This paper proposes architecture of intelligent education services using the context mediator. This context mediator recognizes the situation of the user and provides the user with personalized service suitable for the user. This study is able to support students to more efficiently study on their own by using context mediator.

In order to solve the problem of "energy hole" in wireless sensor networks, this paper proposed a Hybrid Routing Tree Based on Ring Network to avoid this problem. The routing tree base on ring network mode uses the threshold E-s and the middle ring to control the communication style among nodes. The simulation results show that the routing algorithm is effective to avoid the "energy hole" problem and maximum extension the network lifetime.

Stereo image rectification is a preparation of the stereo image pair matching. It is a quick matching method, which can use to increase matching speed. Its result will directly affect the accuracy of the stereo matching. The rectification system of stereo pairs based on the small vision system (svs) is introduced in this paper It uses the data from *.ini (produced by the svs in the procedure of rectification). For the rectification of stereo images, it adopts the undistorted points to obtain the counterpart by the arithmetic method. The method is also superior to implementation, low calculation complexity.

Based on the relationship between debt financing and corporate governance, the paper makes an empirical study on the relationship between debt financing and private benefit of control (PBC) of listed company in China. The findings are as follows: Firstly, considering the special ownership structure in China, debt financing governance effect is dispositive. the effect of debt financing on corporate governance and agency cost of substantial shareholder is insignificant;Secondly. special ownership structure in listed company has insignificant adjustment on the relationship between debt financing and PBC: Finally. the first and largest shareholder equity ratio is essential to PBC, the influence of other big shareholders' restriction in reducing the effects of PBC is not significant.

The complex systems are usually equipped with monitoring systems to ensure the security and the reliability of theirs. Monitoring systems are usually designed according to main systems, and are closed ones. Therefore it is hard to communicate or cooperate to do a job among them, which is needed when many systems cooperate with each other to perform a job, such as associated live broadcasting of multi-TV stations. This paper presented a kind of system architecture of intelligent monitoring based on web services, which combines the monitoring systems together and by means of mobile devices to support system mobile maintenance and fault diagnosis. The system architecture is very powerful and convenient to implement the different system's cooperation.
