The extracorporeal Focused Shock Wave Therapy (EFSWT), is used to treat human tissue disease as a non-invasive technology. Wave field of EFSWT is very complex without standard analysis and modeling method. It is worthy to study the field of ESWT and has significance. According to ultrasonic theory, the parameters of the ultrasound pressure field in core frequency and the transducer are measured, and...
Given a large and complex network, we would like to find the best partition of this network into a small number of clusters. This question has been addressed in many different ways. Here we utilize the simulated annealing strategy to maximize the modularity of a network with our previous hard partitioning formulation for the community structure, which is based on the optimal prediction of a random...
The question of finding the community structure of a complex network has been addressed in many different ways. Here we utilize a clustering method called affinity propagation, associating with some existent measures on graphs, such as the shortest path, the diffusion distance and the dissimilarity index, to solve the network partitioning problem. This method considers all nodes as potential exemplars,...
Along with increasing credit cards and growing trade volume in China, credit card fraud rises sharply. How to enhance the detection and prevention of credit card fraud becomes the focus of risk control of banks. This paper proposes a credit card fraud detection model using outlier detection based on distance sum according to the infrequency and unconventionality of fraud in credit card transaction...
This paper analyses the causes that give rise to the risk of credit fraud and presents an anomaly detection method by using an outlier detection model based on similar coefficient sum. It finds fraud record by computing similar coefficient sum of every two objects and an example is given to validate the model. The result show the feasibility and validity of the method. The research work furnishes...
We investigate two competing products with network effects diffusion on heterogeneous Newman-Watts (HNW) network based on a computer simulation model. Consumerspsila behaviors in our model are determined not only by their individual preferences and purchasing resistances but also by their interactions with others. To analyze the determinant factors in products diffusion we divide network effects into...
