TOPOLOGY OPTIMIZATION OF CANTILEVER BEAM STRUCTURE OF FLAT SAND SYSTEM BASED ON ABAQUS by WANG ShuGuo, LI LiJun, LIAO Kai, YU QiuLiang, CHEN Wei

“…Starting from the internal material layout of the cantilever beam, taking the distortion energy density of the material as the optimization goal, the alterable density method was used to optimize the topology of the cantilever beam in the ABAQUS software, and the most reasonable material distribution is obtained. The optimization results show that when the applied load is 400 N required by the working conditions, the displacement of the front end of the cantilever beam decreased from 4.205 to 1.447 mm, which meets the requirements of the working conditions after optimization. …”

Research on the Collaborative Application of BIM in EPC Projects: The Perspective of Cooperation between Owners and General Contractors by Chengshuang Sun, Min Wang, Fengyong Zhai

“…The results show that the most effective suggestions to promote the BIM collaboration application in EPC projects are “increasing the proportion of BIM application initially strategies,” “increasing incremental revenue of BIM collaborative application,” “reducing costs of BIM collaboration application,” “avoiding excessive hitchhiking,” and “establishing reasonable reward and punishment mechanism.” On the basis of numerical simulation to illustrate the influence of the different initial strategies and parameters on the final decision in different situations, five solutions were proposed for the effective BIM collaboration application between owners and general contractors. …”

Characterization and Calculation of Ecological Water Quantity of Rivers in Plain River Network Areas ——A Case Study of Tongyu River by LIU Hongcai, DING Xiaowen, JIANG Yong, CHEN Qingwei

“…Ecological water quantity is the key to ensuring the stability and health of a river ecosystem.However,the traditional ecological flow has poor applicability when it is used to characterize the ecological water quantity of a river in a plain river network area because of the reciprocating flow of water.Therefore,studying methods of characterizing the ecological water quantity of rivers in a plain river network area has important practical significance.After analyzing the characteristics of rivers in a plain river network area,this paper proposes using ecological water level to characterize the ecological water quantity of the rivers in the plain river network area.Taking the Tongyu River as an example,it calculates the ecological water level of the Funing (Tong) section by the wetted perimeter method and the biological space method.The obtained minimum ecological water level of the Funing (Tong) section of the Tongyu River is 0.20 m.The comparison with the requirements of the relevant guiding documents shows that characterizing the ecological water quantity of rivers in a plain river network area by ecological water level is reasonable and that the calculation results are reliable.The research results can provide a new method and idea for the determination and management of the ecological water quantity of rivers in a plain river network area.…”

Student knowledge tracking based multi-indicator exercise recommendation algorithm by Bin ZHUGE, Zhenghu YIN, Wenxue SI, Lei YAN, Ligang DONG, Xian JIANG

“…Personalized exercise recommendation was an important topic in the era of education informatization, the forgetting laws of students in the learning process were ignored by the traditional problem recommendation algorithm, which failed to fully tap the students’ knowledge mastery level and the common characteristics of similar students, insufficient, could not reasonably promote students’ learning of new knowledge or help students find and fill omissions.In view of the above defects, a multi-index exercise recommendation method based on student knowledge tracking was proposed, which was divided into two modules: preliminary screening and re-filtering of exercises, focusing on the novelty, difficulty and diversity of exercise recommendation.Firstly, a knowledge probability prediction (SF-KCCP) model combined with students’ forgetting law was constructed to ensure the novelty of the recommended exercises.Then, students’ knowledge and concept mastery level was accurately excavated based on the dynamic key-value knowledge tracking (DKVMN) model to ensure that exercises of appropriate difficulty were recommended.Finally, the user-based collaborative filtering (UserCF) algorithm was integrated into the re-filtering module, and the similarity between student groups was used to achieve the diversity of recommendation results.The proposed method is demonstrated by extensive experiments to achieve better performance than some existing baseline models.…”
