	abstract = {This paper designed and developed a teaching robot - three degrees of freedom manipulator based on Fischer creative combination model platform. Firstly, the overall structure of the robot was analyzed to determine the drive programs, and then the manipulator structure was assembled and established in accordance with the modular design approach. Finally, the robot control system was studied. This paper focuses on the hardware design and control system of the robot. Practice has proved that the teaching robot we designed has the advantages of low cost, easy to regulation, good repeatability and it has good promotion and application prospects in the teaching field.},

	abstract = {In order to solve the problem of rotation invariant texture image retrieval, an image retrieval algorithm based on Log-Polar and nonsubsampled contourlet transform (NSCT) is proposed. Log-Polar transform was first applied to texture image to convert the rotation to translation. Then, translation invariant NSCT was employed to decompose the transformed images. Standard deviations, energies and entropies of the different directional subbands features were calculated to make up a 45-dimension feature vector. Finally, Canberra distance was used to compute the comparability of this feature vector to retrieval images. The experiment results showed that the proposed algorithm was able to obtain a higher recall rate.},

	abstract = {Ladle is an important container in metallurgy industry, and its lifetime is very important for the natural production of enterprise. The stand or fall of refractory lining of ladle decides its lifetime, yet thermal stress is the direct reason of causing refractory lining breakage. In this paper the structure of ladle mainly by changing the structure of bottom with finite element method is designed, and three scheme models are put forward. By analyzing and comparing stress field of the three ladle models, finally an optimization scheme is put forward. The experiment results indicate that the lifetime of ladle gains obvious increasement, and the rationality and practicability of the scheme have been proved. The method is feasible to improve ladle{\textquoteright}s lifetime.},
