There are some problems in optical education such as insufficient flexibility, individuality and adaptability to students who need information and education at present. The development of mobile internet and technology provides support to solve these problems. Basic characteristics, advantages and developments of these techniques used in education are presented in this paper. Mobile internet is introduced to reform the classroom teaching of optical courses. Mobile network tool selection, teaching resources construction and reform in teaching methods are discussed. Academic record and sampling surveys are used to assess intention to adopt mobile internet and learning effect of academic major of students, the results show that high quality optical education can be offered by adopting mobile internet and technologies in traditional instruction.
There are some problems in Basic Oxygen Furnace (BOF) steelmaking end-point control technology at present. A new
BOF end-point control model was designed, which was based on the character of carbon oxygen reaction in Basic
Oxygen Furnace steelmaking process. The image capture and transformation system was established by Video for
Windows (VFW) library function, which is a video software development package promoted by Microsoft Corporation.
In this paper, the Radial Basic Function (RBF) neural network model was established by using the real-time acquisition
information. The input parameters can acquire easily online and the output parameter is the end-point time, which can
compare with the actual value conveniently. The experience results show that the predication result is ideal and the
experiment results show the model can work well in the steelmaking adverse environment.
Presented is the analyses of influence of Hadamard coding system on imaging error in laser coding Synthetic Aperture Radar. The result shows that using Hadamard coding can increase the amplitude of echo signal and reduce noise. Coding and sampling circuit possess good linearly respond property.
