A multi-twister six-channel banknote sorting device is designed for the financial market and public transportation system, to solve the problems of traditional devices such as single structure, large size and expensive price, fhe core of the device and innovation points lay on notes separation mechanism Using friction between note and twist wheel and different gears of synchronous wheels, we design the device with four parts: notes separation structure, notes denomination recognition structure, the structure of the paper currency sorting, and data feedback. The paper currency denomination recognition mainly uses HSV color sensor principle, and data feedback is the LCD display which shows the denomination and quantity of the bill. Paper currencies were sorted by using a combination of eight wheels and the steering control. There are one entry and six exports, and currencies with different denominations are sorted. It greatly saves space. Physical prototype shows that the device can process six different denominations of chaotic notes, it is stable, high sorting speed, small size, high accuracy, low price, clean energy consumption, low visibility, and expandability. It can be used in the public transportation, finance and other related cash processing industry to reduce the sorting of human resources and workload, and improve work efficiency.

In this paper, an approach of recovery of paper scraps was proposed. First of all, the number of word boundary continuous points was used as the character feature, Then gray feature of the boundary text was extracted by using the continuous eight connection method. The continuous point number feature matrix based on the gray feature is obtained through the feature extraction. Finally, the ordering of the fragments is sorted by position, computer programs are developed by C language and according to this algorithm. They are applied in a stitching experiment for pieces of scrapped paper, the results show that this algorithm meets the design requirements. [ABSTRACT FROM AUTHOR]

In this paper, an approach of recovery of paper scraps was proposed. First of all, adjacent bits of paper text line feature were selected, and each piece of paper was used as a node of the graph. It established a grid graph model based on the line feature of text, and narrowed the set of matching scraps of paper by considering both sides of pieces line the matching. Function values of both positive and negative similarity were added as similarity of scraps of paper, when the similarity function value reached minimum. It shows the difference of gray value of two scraps of paper writing disconnection can reach the minimum. Finally, the simulated annealing mechanism was introduced to optimize the matching process of the set of matching pieces of paper.

The air flow with sand produced in deep water gas wells has a high flow rate, causing the erosion of screen to be more serious, which is easy to cause sand control failure, affect production and aggravating the cost of workover. In order to accurately monitor the erosion of sand control screens in deep water gas wells, it is more practical and valuable to use the short-time, low-cost simulation experiment to research. In this paper, the overall geometric model of the screen and the geometric model of the pore are constructed, and they can be modified in stages to match the change of pore size during the erosion process. The multi -angle screen erosion model of discrete particles is established and the gas-solid coupling flow model is introduced. The sub-relaxation iteration is used to iteratively calculate the two-phase flow field distribution and the erosion rate of the screen, and a simulation method of screen erosion is formed by applying the XX well for erosion analysis. The simulation experiment of sand control screen erosion proposed in this paper provides a research method and theoretical basis for the optimization of sand control screen and the calculation of erosion rate in deep water gas wells, which is of great significance for ensuring the safe and efficient development of marine oil and gas resources.

The spectrum of the image reflects the distribution of image energy in the frequency domain. The ratio of the high and low frequency components of the spectrum reflects the distribution of edge information and smooth information in the image. Through statistical analysis of the spectral distribution of dear and blurred images, this paper proposes an image clarity and fuzzy discrimination method based on sub-band spectral information. First, the spectrum energy outside the frequency radius is calculated, and the characteristic curve of the residual energy of the spectrum is obtained. Secondly, according to the residual energy curve, the normalized fuzzy judgment parameters are obtained. When the fuzzy parameter is less than a certain threshold, the image is judged to be a blurred image. The experimental results show that the parameter proposed in this paper can quantitatively measure the degree of image blur, and has the advantages of fast and simple judgment process and high classification discrimination.

Experimental teaching has always been an indispensable part of engineering education. And it always plays an important role in cultivating students’ practical ability, independent thinking ability, innovative thinking and divergent thinking. But simulation experiment and physical experiment cannot be unified in the circuit teaching experiment at present. In order to solve this problem, this paper proposes to combine organically the simulation circuit experiment with physical circuit experiment, and synchronously operate them. This paper uses the WEB publishing to achieve remote experimental operation. Multisim is used as the circuit simulation platform, and NI Eiviss II is used as the physical circuit hardware platform. Multisim circuit simulation experiment and physical circuit experiment are implemented by LabVIEW to realize the combination of simulation experiment and physical experiment. Students do explore experiments in simulation experiment firstly, and then do physical experiment. And this paper uses LabVIEW to develop the experimental man-machine interface.

The laboratory and experimental teaching in universities is an important carrier to cultivate high level technical talents with innovative spirit and practical ability, an important pillar for improving the innovative ability of universities and promoting the transformation of scientific and technological achievements, a symbol of the strength of universities. The paper elaborates the existing problems in the construction of laboratory and experimental teaching, puts forward to promote the laboratory construction and the experimental teaching reform by the five in one way, i. e., "production, study, research, teaching and competition". These measures promote the development by the alliance and cooperation between school and enterprises, promote the construction by researching and developing the experimental teaching equipments independently, promote the improvement by the evaluation of experimental teaching level, promote the promotion by reforming the experimental teaching, promote the effectiveness by the students ’ scientific and technological teams, projects and competitions. The paper summarizes up the management ideas and work practice of the school for the laboratory construction and experimental teaching reform in recent years. [ABSTRACT FROM AUTHOR]

The establishment and classification management of university experimental technology posts have become important trends of personnel system reform in recent years, it is not only the external environment built by teachers’ post classification management reform, but also the internal demand for the construction and development of university experimental technology team. Combined with the main background of the post arrangement and classification management, this paper focuses on the basic mode of the post arrangement and classification management scheme of experimental technology of some domestic colleges and universities. Based on the mode, this paper gives a systematic analysis on the actualizing approaches of experimental technique of post setting and classification management program;and at the same time, technical difficulties in practical work of colleges and universities have been also discussed.
