Since 21 century, with the wide spread in family and public, network has been applied in many new fields, and the application in classes is of no exception. In traditional education, teachers give lessons to students face to face. Hence, the teaching quality depends largely on the quality and initiative of the individual teacher. However, the serious disadvantages of this mode are that teachers completely dominate the classroom and may ignore the subjective cognition role of the students, which may be bad for the growth of creativity and the innovative thinking ability. Obviously, traditional education mode cannot meet the requirements of the this new era which leads to the booming developing tendency of the network. As a new teaching measure, scientifically combining modern information technology and teaching practice, network teaching not only changes the traditional education by the means and form, but even also gives new meanings to teaching concept, process, method as well as teacher-student role and other deep levels. With the help of network teaching system, on-line classroom learning, relevant information systematization, standardization and automation, this system provides students with an efficient online learning method with high quality. This also helps to solve the disadvantages of the traditional teaching mode and promote the teaching methods to a new stage. It improves the network teaching platform, enriches the network teaching resources, and establishes a network teaching system, so as to improve information quality of teachers and students and assist in improving teaching quality of schools. © Owned by the authors, published by EDP Sciences, 2016.

This thesis studies and develops an agent-based on-line monitoring and diagnosis system. In order to make production line automation, yield high production rate, and enhance the ability of market competition, an effective way is to ensure facilities running smoothly and to reduce the manpower monitoring. Meanwhile in order to reduce the cost of development and enhance the feature of reuse, we use a communication interface to integrate and interact information among developed softwares. Through this system, users may easily monitor and diagnose the machines on production lines through user interfaces, Consequently, it is of greatly help to lower the cost of personnel and enhance the ability of market competition. © (2014) Trans Tech Publications, Switzerland.

This paper mainly studies image design which grey pictures of the traditional culture are applied in modern 2D cartoon. Through Mining and reference in three aspects of Character modelling, the overall attitude, expression means to the shandong flapping gray pictures, 2D cartoon image design can form style of cartoon image Of romantic exaggeration and simple. Image design of cartoon film mulan's organically combines style pictures of the shandong grey modelling, and creates a distinctive artistic form and image design work of rich connotation of cartoon. Through analysis and reference to the expression means, the article provides a new thought and method for the cartoon image design in the future, widen the space of thinking, make modern 2D cartoon image design a new direction and breakthrough. © 2015 IEEE.

To investigate antiwear properties of straight type diesel engine cylinders, an SRV IV wear tester was used to measure dynamic friction coefficient and wear depth by simulating working condition of cylinder liner and piston ring. The worn surface topography was observed through scanning electron microscope. The results show that the wear of piston ring is greater than that of cylinder in the same pair of friction. In three groups the average friction coefficient and the wear amount of honing cylinder is the minimum, followed by the smooth cylinder. The wear amount of grooves - micropitting composite textured cylinder is the maximum. The main wear form of three groups cylinders is fatigue, accompanied by two body abrasion. © (2014) Trans Tech Publications, Switzerland.

Currently, the statistical capacity of the grassroots statisticians is not good enough. And their statistical report would be consulted by the local governments and institutions to make some major decisions, so their statistical capacity needs to be improved urgently. In this paper, some common formulas and algorithms are introduced to train the grassroots statisticians effectively, such as fitting function, fourfold table chi-square test, the variation index and some necessary mathematical explain of Excel. In addition, some statistics examples are processed to show these methods. © 2014 IEEE.

The thesis studies China's major men's business casual sweater brands' price parity systems. It chooses the three online shopping websites Taobao, Tmall and 360 buy to investigate and analyze China's eight major men's casual business sweater brands' prices. Based on men's sleeveless sweaters' price, it tries to establish a price parity system for national men's business casual sweater. Through analysis and pratical study of the case brands, it comes to a conclusion that the system has certain representativeness and complies with the market. Having been tested by the practices, the system is practical and can be used in deciding the prices of national business casual sweaters.

In the present research, the authors propose a parallel certificateless proxy re-encryption scheme (PCL-PRE) by applying parallel computing thought into proxy re-encryption algorithm, basing on the current technical background of multi-core CPU, in order to access and control data in cloud storage safely. Data owner adopts symmetric encryption key (DEK) to encrypt sensitive data, and also encrypts the DEK using proxy re-encryption algorithm, save such encrypted content parallelly in the cloud data center. As a semi-creditable proxy node, cloud storage center encrypts the data owner's DEK according to the access control list, converts to ciphertext that multiple receivers can use their private key to decrypt; however, during the entire process, no plaintext is accessible. The receivers can decrypt the ciphertext upon receipt. The scheme is based on random number multiplexing technique, and it is capable of optimizing message parallelly and aggregating in combination with ciphertext, therefore further improving the transmission efficiency. Experiments show that the present research is obviously advantaged in efficiency. © 2016 American Scientific Publishers All rights reserved.
