NFC is a short-range communication of non-contact, combining NFC and smart phone in the field of mobile payments has broad application prospects. Unity3D is the most convenient and reliable software to realize cross-platform application transplant in the current field of game development. Unity3D-based...

How to improve the efficiency of guiding disassembly sequence is the main research contents of augmented reality maintenance. To furnish the disassembly sequence to the system efficiently, assembly disassembly hybrid hierarchical graph model is established based on interference matrix between the assembly...

This paper defined the material archives information management by analyzing the bill of the large-scale custom-built ambry material. This paper built the information management platform of large-scale custom-built ambry material technology archives preliminarily, including product mix, material sorting,...

This paper applies the SC model and SVJD model to artificially generated data, and we put forward a forecast model that hybridizes genetic algorithm, principal component analysis and artificial neural network methods. This article utilizing genetic algorithm to search for the initial weights of the BP...

Enormous amount of information on the Internet, there are several of information and it is so complicated. Information retrieval is of blind and too much redundant information is in search results. In order for a user to much more effective at getting the information they needed, This paper researches...

Control can make things develop following the planning direction, and keep the change of deviation from target in the permitted limits. Ecological control eco-control combines ecology with cybernetics, which researches on the process of information transfer, transformation, treatment for the ecosystem...

Based on Machine Vision, the paper research a method to detect obstacles and calculate the distance between the obstacle and moving vehicles. First it uses the shadow detection method to determine approximate location of the obstacle and adopt corner detection method to detect the obstacle contour information....

In this paper, according to the principle of Hough transform, using the multi - directional image information of an object to calculate the pixel points of the object in the space, and get the real three-dimensional image from the object surface texture mapping which is composed of pixel points. This...

In mobile learning concept . In the first part, the reconstruction of the digital learning resources classification model is established, and then the the cloud based education platform "teacher student subject knowledge ontology" three-dimensional space application model based on. Finally, it designs...

Route planning and optimization is significant for milk run system. Therefore, taking minimizing the transportation cost as objective, a route optimization model of milk run was developed. For the discreteness of solution, a discrete firefly algorithm based on bi-layer coding was proposed. Finally, through...

Aiming at the problems that it is difficult to calculate and establish accurate mathematical model in the structure optimization with discrete variables, the Lagrange multiplier method is proposed to deal with the constrain conditions in the improved genetic algorithm which solved the problems of “premature”...

Process fault diagnosis is a topic of significant practical interest. Bayesian fault diagnosis methods have been developed to identify the problem source from all monitors of the process. However in a large scale industrial process, taking all the monitors into account not only increases computation...
