Application of Improved Graph Theory in Planning of River and Lake System Connection by JIANG Yu, ZHANG Qionghai, YAN Meng

“…This paper first analyzes the river system characteristics,hydrodynamic conditions,and status quo of water environment in the tidal river network area.On this basis,a preliminary connection scheme is then drawn up by the concept of connectivity in the graph theory based on “flow resistance” and the connectivity diagnosis and optimization method of river systems based on the “shortest path” idea.The scheme is further refined by a one-dimensional hydrodynamic mathematical water quality model.The results reveal that the scheme of minimum resistance connection by the graph theory is the optimal scheme of structural connectivity,and the problem of connection failure caused by the sluice control mode is solved after the scheme is refined by the mathematical model.This method can quickly diagnose the structural connectivity of river and lake systems,enrich the diagnostic means of river and lake connectivity,and provide a reference for the planning of river system connectivity in the tidal river network area of the Pearl River Delta.…”

Multi-objective Optimization Design of RV Reducer Considering the Cycloid Gear Profile Modification by Wang Quan, Zeng Lilei, Qin Zhengzheng

“…In view of the fact that the influence of cycloid gear profile modification on contact force is not taken into account in the structural design of RV reducer，a multi-objective optimization design method for the structure of RV reducer considering cycloid gear profile modification is proposed.Combining the theory of tooth profile modification with the calculation of contact stress of cycloidal gear，considering the factors of volume，efficiency and contact stress，an optimization mathematical model with small volume，high efficiency and low contact stress of cycloidal gear as multi-objective function is established.The solution is carried out by using NSGA-II algorithm，and compared with single-objective optimization method.The results show that compared with the original design，the volume of RV reducer decreases by 21.24%，the efficiency increases by 2.03%，and the contact stress of cycloid wheel decreases by 20.26%.Meanwhile，the multi-objective optimization method has higher comprehensive performance than the single-objective optimization method.…”

Debates and Discourses on Ornament in Contemporary Architecture by Deniz Balık Lökçe

“…This book distinguishes itself from other current publications because it is one of the first works to discuss ornament from a new viewpoint by graphically analyzing a variety of twentieth and twenty-first-century buildings in terms of form, screen, structure, and surface. The book shows that ornament, as an integral element, is integrated to material, structure, and form, rather than being extrinsic and additional, which brings us to the etymology and the origins of the term. …”
