Forming excellent learning climate is vital both for a school and for students. Traditional researches tend to analyze the problem in theory so that we can hardly find papers with precise mathematical models. In this paper, we construct a small-world network to represent the personal relation network among school students, and use all the students’ learning attitudes to represent the school’s learning climate. Based on it we build an learning climate formation model with considering students’ consistent degree, the friendly degree among students and the influences of teachers and parents. During the simulation, we analyze the effect of different impact factor on learning climate formation. It proves teachers and parents have a significant impact on the formation of learning climate. They should take appropriate measures to help students form favorable learning habits.

A novel Multi-objective Ant Colony Optimization algorithm for shortest route problem (MACO) is proposed. Firstly, the pheromone on every path segment is initialized to an initial value and ants are randomly distributed among cities. Secondly, self-adaptive operator is used, namely in prophase we use higher probability to explore more search space and to collect useful global information; otherwise in anaphase we use higher probability to accelerate convergence. MACO algorithm adopts self-adaptive operator to make the search scope reduced in anaphase, thus the search time of this algorithm is reduced greatly. Real shortest route results demonstrate the superiority of MACO in this paper.

In order to meet the testing requirements of task scheduling algorithms, this paper proposes two algorithms for generating random adjacency matrixes. One algorithm is used for generating random adjacency matrixes representing either directed cyclic graphs or directed acyclic graphs. The other algorithm is used for generating directed acyclic graphs only. The paper analyses the characters of elements of an adjacency matrix, and applies a square matrix with elements falling into a Gaussian distribution and the technique of descending order to achieve a random adjacency matrix. We conduct experiments on our algorithms using MATLAB. The experimental results show that the algorithms have high efficiencies, and adjacency matrixes which represent task graphs with dozens of nodes and dozens of edges can be generated in one minute. Those random adjacency matrixes generated by the algorithms are suited for task scheduling algorithms which use random adjacency matrixes to verify validities.

The paper proposed a novel method for remote sensing image segmentation based on mixture model. The remote sensing image data would be considered as Gaussian mixture model. The image segmentation result was corresponding to the image label field which was a Markov Random Field(MRF). So, the image segmentation procedure was transformed to a Maximum A Posteriori(MAP) problem by Beyesian theorem. The intensity difference and the spatial distance between the two pixels in the same clique were employed in the potential function. The Iterative Conditional Model(ICM) is employed to solve MAP. In the experiments, the method is compared with the traditional MRF segmentation method using ICM and simulate annealing(SA). The experiments proved that this algorithm was more efficient than the traditional MRF one.

This paper presents a new technology using Bismuth-film to determinate lead instead of mercury film. It is proved in the experiment that, in the optimum measuring situation (when the pH is 4, deposition time is 150s, and the deposition potential is 0.8.), the lead concentration and stripping peak current shows a good linear relationship in the measuring range of 10 to 110ug/L, which is I=0.1002C+0.0539. The experimental analysis shows that the concentration of lead in tea samples is 1.667μg / g, and the recovery rate is 91.2% ~ 101.8%. It is proved that the method of bismuth film electrode is used to measure lead with advantages of convenience, speediness, sensitivity and accuracy, etc.

To reveal the change regularity of drivers' memory on traffic sign information over time, fading model of drivers' short-term memory was established. Based on fading factors and the shape of fading curve, power function was employed in describing fading trend of drivers’ short-term memory. A typical route was chose in urban road network, and a car was employed to do the experiment. Based on theory of psychology and memory, the impact of traffic sign information on drivers’ short-term memory was studied, and the fading model of drivers’ memory for traffic signs information was established. The paper verified Ebbinghaus’ forgetting curve and proposed new parameters for drivers of different age/driving age and gender. Finally, the fading model was applied into the designing and layout of traffic sign in an intersection.
