Learning analytics can give powers to teachers and learners to optimize their teaching and learning. This paper presents the design and implementation of learning analytics system for teachers and students based on a special LMS -- THEOL LMS, which is commonly used in blended learning in universities and colleges. The technical architecture of learning analytics system for teachers and students is...
In order to protect Chinese ancient buildings, an ancient wooden building is taken as an example to study its progressive collapse under vertical transient loads. By LS-DYNA program simulation model of the ancient building is built. Then a structure member is considered inactive and failure loads in vertical direction are applied to the inactivation point to make the structure collapse. During the...
In this paper, we discuss the loss-averse newsvendor problem. Firstly, we develop a basic model in which the service-level constraint is not considered. And we get the optimal order quantity and the optimal expected utility under the basic model. Then, we add a service-level constraint into the basic model. And we also get the unique optimal order quantity and the optimal expected utility. Furthermore,...
Vehicles report-stop fraud is an important factor of highway fees loss, which is more than the proportion of 20% of the total loss in statistics. The paper uses data mining and data warehouse technology to resolve the deficiencies of traditional data management information system on the analysis of vehicles report-stop fraud. The significance of the issue and mining goal were described, and the correlational...
Chinese ancient buildings are mainly made of wood. For thousands of years they have experienced sorts of earthquakes but remain intact. In this paper, we took Ying-Hua Palace in the Forbidden City in China as an example. By simulation methods we carried out analysis on dynamic character as well as a seismic capacity of the building. By introducing 2-node semi-rigid spring elements, we simulated tenon-moritse...
