Spatial relation extraction is very important for remote sensing application, but most existing topological models hardly describe the order property of transformations among the topological relations. This paper proposed a new method to extract inclusion relation of image based on topology map in the process of multi-level image classification.

Passenger and freight train scheduling problem on double-track railway line is considered by using Ant Colony Optimization (ACO) algorithm. The aim is to reasonably arrange the dispatch sequence of the trains to minimize the total run time. The constrains in train scheduling problem are considered and the model is established. Due to the complexity of train scheduling problem, this problem is solved by ACO and implemented by programming. A case study is presented to illustrate the solution. The results illustrate that the proposed method is effective to solve the scheduling problem on double-track railway line.

The bearing capacity of slime friction pile based on the Mohr-Coulombs strength criterion couldnt make full use of the potential strengths ability of rock-soil. But the double shear unified strength theory can depict really the bearing characteristics of rock-soil because it can consider the effect of intermediate principal stress comprehensively. On this condition, based on the Mindlins displacement solution and the double shear unified strength theory, a calculated formula of bearing capacity was proposed for the slime friction pile, and then the distribution regularities of lateral friction-resistance force for the slime friction pile were discussed.

Flower-like, sphere and lamellar structures of copper sulfide have been prepared by an electrochemical method with PAM hydrogel as template. The unique synthetic method required no multiple growth steps typical of other methods, and just utilized the electric currents to drive the ions to realize the controlling the resultant morphology in the PAM hydrogel system. The structure of product was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The morphology of these structures could be controlled by adjusting the content of PAM in hydrogel, and the intension of electric current.

Based on the analysis theory of plasticity limit, a formula of virtual work and an energy equation are established for the stability analysis of anchored soil slope, in which the soil nails and anchors are regarded as the internal structure which consumes the external power in the soil slope engineering.In the meantime, based on the simplified method of circular slip, another formula which can consider many factors such as the self-weight of slope, earthquake force, pressure of pore water and the force of anchor, is established to analyse the whole stability of anchored soil slope. It has important values for perfecting the analysis method of soil slope.
