Analyze of university-industry-research cooperation’s characteristics which the university is the main target, and each case has been specifically addressed, characteristics of the cooperation were discussed, and detailed analysis of the relationship between the characteristics of the main features of each. From the perspective of their own cooperation feature, further discusses the characteristics of cooperation.

According to Assemble line balancing (ALB) problem which is widespread in manufacture, we establish a mathematical model and present our improved algorithm that is based on Heuristic rules, which adopt cumulative ranked positional weight as a basis of task assignments and schedule the orders of branches traversal. After that we can find an optimal solution to the balancing problem efficiently. The result of examples given by this paper shows our algorithm has a good performance.

Hydraulic torque converter’s performance testing is very important in the product’s development and production. In order to accurately and rapidly test various performance parameters of the hydraulic torque converter, a torque converter performance test system was developed based on the PC and VB development platform in this paper. It can improve computing speed and programming capability, decrease artificial involved times, realize the data analysis processing’s automation.

Aiming at problem of low coal mining rate and environmental pollution by gangue, replacement mining technology of source recovery by excavating large span roadway and backfilling with gangue is put forward in this paper. Then combined control technology of roof cable truss and coalside cable-channel steel is applied to support the large span roadway, its control mechanism is discussed and the combined support scheme is defined by way of numerical simulation. Besides, according to the practice production condition, the replacement system which consists of gangue pretreatment, transport and replacement is established, achieving harmonic extraction of resource recovery and environmental protection and providing scientific basis and technological means for resource recovery under other geological conditions.

In this paper, theoretical constitutive model, numerical tool, viz., RFPA code and servo-type testing machine, viz., RMT-150B rock testing systems were briefly described, respectively. Then, based on theoretical analysis, numerical simulation and experimental tests for rock specimens in uniaxial compression, the relations and differences between theoretical, numerical and experimental results, especially the complete stress-strain curves, were contrastively analyzed and investigated. The reason for these relations and differences among results was also proposed in this paper.

Radio astronomy telescope can get information from invisible universe by receiving electromagnetic waves. Difference from optical telescopes, there exists many difficulties for making the public understanding the radio astronomy phenomenon. In this paper, we will introduce a new platform for radio astronomy science popularization education in order to help public know radio telescope and radio astronomy. The platform consists of a 0.8meter parabolic antenna, a wide bandwidth low noise amplifier (LNA) and a Software Defined Radio (SDR) terminal. Based on SDR terminal which covers the band from 70MHz to 6GHz, we can get some strong emissions such as the Neutral hydrogen, solar radio bursts and so on in this band. People can carry out many radio astronomy experiments focusing on science popularization by this platform. This new science education tool can interest high school students in science and technology, also students can understand how radio telescopes works.

Based on the classical Mayer-arc model, this paper establishes the equivalent circuit of traction network for AC25kV electric railway from the essence of contact loss discharge. The voltage waves of contact loss arc at different moments are obtained by MATLAB/simulink. Through the analysis, it can be confirmed that the EMI (electromagnetic interference) with broad band and high amplitude will appear at the moment the contact loss between pantograph and catenary happens. Finally, relevant measures are given to avoid the probability event of contact loss.

It is quite inadequate in providing formula retrieval function by traditional retrieval techniques used in full-text information retrieval system. The main reason is that there are many difficulties to extract the keywords of the mathematical formulas. In this paper, a detailed analysis of the structural characteristics of mathematical formulas and existing index mechanism of mathematical formula searching engine is fulfilled. Then a full-text index (named SLIndex) of mathematical formulas with B+ tree structure is designed and implemented which extracts the structured logic sub-tree feature as keywords of formulas and employs inverted index. Finally, a formula search engine model based on SLIndex is implemented in Apache 2.0 web server.

On the basis of the second-order upwind scheme, combined with the flux splitting method, we derive a uniform multi-conductor transmission line time-domain calculations. This method is a direct time-domain discrete numerical method with second order accuracy. It does not have any special requirements for circuit and the application process and complex transformations which lead to facilitate the preparation of the program. Numerical experiments show that this method of preparation of general purpose computing program has roughly the same computational efficiency with the traditional leapfrog scheme and at the discontinuous solutions, there are no non-physical oscillations. It can easily be used to calculate a uniform multi-conductor transmission line coupling.
