In order to study the academic guidance of students of colleges and universities from the perspective of "Internet + Education", taking Dongguan Career Technical College as an example, this paper concretely analyzes and explores the student guidance of the colleges and universities which carry out "Internet + Education" mode, then defines the connotation of "Internet + Education" and the rational mode of the academic guidance from this perspective, finally it effectively enhances the effectiveness of the student academic guidance work of Dongguan Career Technical College and provides reliable reference for the relevant guidance work in the future. This paper shows people a new mode of education in order to make "Internet+ Education" mode be fully integrated into colleges and universities and to make colleges and universities can get a new level in education.

This paper has proposed a new method for welding procession monitoring and controlling. A Cartesian welding experimental platform is firstly setup. Then welding experiments can be performed and several groups of welding images can be captured by the vision sensor. A composite filtering system is set up and used to filter the weld arc disturbance. Then median filter and grey level transformation operations are performed to enhance the contrast of processing district on the image. On this basis,the grey centroid of weld pool C, the width of outer weld pool W, the width of inner weld pool N and welding current I are seem to be the heat distribution condition parameters. The weld seam error e and the welding penetertion condition p are used to be the welding conditon detection parameters. A BP neural network is used to set up the relationship between the heat distribution condition parameters and the welding condition detection parameters. In the end, several testing experiments are performed. The resluts show that the pediction value of the tracking error are fit to the measuring value, and the average tracking error is 0.011 mm. The accuracy rate of the model for welding penetration prediction is up to 95%. © 2017 Springer Science+Business Media, LLC

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.

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.
