A new computational algorithm is introduced for solving scattering problem in periodic structure. The PML technique is used to deal with the difficulty on truncating the unbounded domain while the DSC algorithm is utilized for the spatial discretization. The present study reveals that the method is efficient for solving the problem. 展开更多

In aircraft structural dynamic design the matching of guns with their supporting structure is one of the most important tasks on which hinges the success or failure of the structural design. The design curves for matching guns with their supporting structure can be obtained from response calculations of the plate-spring system supporting the gun on the ground,the model structure tested on the ground and the actual structure.A set of matching curves is given for engineering application.Then,the matching design can be accomplished by means of impact load spectrograms so as to perform an optimal structural design and to make further improvements on dynamic design program. 展开更多

The concept WALKING on structures is proposed, and the partial ordering between a structure and a query structure (substructure) is also created by means of WALKING. Based upon the above concepts, authors create the Heuristic-Backtracking Algorithm (HBA) of structural match with high performance. In the last part of the paper, the applications of HBA in molecular graphics, synthetic planning, spectrum simulation , the representation and recognition of general structures are discussed. 展开更多

Different types of capital are better suited to financing technologies with different risk profiles,and structural matching between finance and technology may critically influence economic growth.Using cross-province panel data from China,we estimated the impact of the matching relationship between regions'financial structure and technology level on economic growth.We show that:(ⅰ)the matching relationship had a statistically significant positive impact on economic growth;(ⅱ)structural mismatching reduced economic growth in comparison with the optimal matching point;(ⅲ)structural matching better facilitated economic growth in more developed regions;and(ⅳ)capital accumulation and technological progress were two of the main channels through which matching influenced economic growth.We address potential endogeneity concerns and perform robustness checks,and our results remain valid.Our findings provide convincing evidence for the optimalfinancial structure theory and explain China's rapid growth despite its comparatively underdeveloped securities market. 展开更多

Financial systems generally operate under two different models:one where capital markets play a primary role in financial transactions and resource allocation(market-oriented model),and another where banks are the central institutions for these activities(bank-oriented model).The degree of investor protection afforded by the legal system varies across these systems.What is the most efficient alignment between financial structure and investor protection?This paper attempts to quantify the structural matching relationship between the financial structure and investor protection in various countries,and examines empirically the impact of this relationship on economic development.Using a sample of cross-country panel data,it finds that the degree of structural matching was positively related to economic development.Both the combination of a securities market and strong investor protection and the combination of a banking system and weak investor protection can contribute to promoting economic development.It extends the law and finance theory framework,enhances the analysis of scenarios with weak alignment between financial structure and investor protection,explains the growth path of developing countries,and highlights the diversity and the dynamic nature of the optimal financial structure. 展开更多

Based on mode acoustic emission theory,the paper analyses the acoustic emission analog signal of thin steel plate using matching pursuit,then obtains the characteristics interpretation of the different frequency signal energy concentration degree; Combined with four-point arc positioning method,the papers researches the damage localization of the plate-like structure. Simulation experiment shows that this method can accurately detect and locate the damage. This can provide data support for further imaging research based on time reverse theory. 展开更多

Privacy preservation is a primary concern in social networks which employ a variety of privacy preservations mechanisms to preserve and protect sensitive user information including age,location,education,interests,and others.The task of matching user identities across different social networks is considered a challenging task.In this work,we propose an algorithm to reveal user identities as a set of linked accounts from different social networks using limited user profile data,i.e,user-name and friendship.Thus,we propose a framework,ExpandUIL,that includes three standalone al-gorithms based on(i)the percolation graph matching in Ex-pand FullName algorithm,(i)a supervised machine learning algorithm that works with the graph embedding,and(ii)a combination of the two,ExpandUserLinkage algorithm.The proposed framework as a set of algorithms is significant as,(i)it is based on the network topology and requires only name feature of the nodes,(i)it requires a considerably low initial seed,as low as one initial seed suffices,(ii)it is iterative and scalable with applicability to online incoming stream graphs,and(iv)it has an experimental proof of stability over a real ground-truth dataset.Experiments on real datasets,Instagram and VK social networks,show upto 75%recall for linked ac-counts with 96%accuracy using only one given seed pair. 展开更多
