Web-based language learning (WBLL) environment has provided English education a new arena where learning and teaching activities are vivified by the feats of computer and internet technology. A full development of learner autonomy can conduce to success in web-based English learning. This paper aims to find out ways to improve learner autonomy to achieve Chinese students' success in web-based English...
This paper utilizes photographic surveying principle and uses digital camera to shoot and monitor the mine surface, and quickly collect mine spatial data. Based on the data, a 3D model of mine surface is built. The large scale maps of mine are made. Based on coordinates and 3D model in the period of different time, changes of mine surface are get obtained. The 3D model can help to get the shape of...
According to underwater terrain characteristic, the multi-index synthetic evaluation theory is used for calculating matching area of an underwater terrain-aided navigation system in this paper. Considering the terrain elevation standard deviation, roughness, terrain correlation coefficient, topographic information entropy and other crucial terrain characteristic parameters on the effect of navigation...
Combining with the usual requirement and multi-constraint conditions of examination arrangement, the math model of examination arrangement is built, and a sub-rule algorithm for arrangement of examination seat based on the proportion of examinee is proposed. Then the detail step of the algorithm is given, and the complexity is analyzed. The Analysis and experiment result show the algorithm can control...
The multi-constraint conditions, including the entrance examination for college, the region and the dormitory classification and so on, were analyzed and studied enough by assigning management dormitory reasonably. A new backtracking algorithm based on matrix storage was proposed, and the realization detail of the algorithm was discussed. Further, the complexity of the algorithm was analyzed. The...
One difficulty in distance teaching is how to determine static and dynamic abilities of student, which teaching strategies can be adjusted according to individual differences and learning effect can be improved. This paper proposes a structured student learning model. Teaching system can teach students according to their aptitude based on this model. The distance teaching adaptability can be achieved...
