Active shape models (ASMs) have been widely used in segmentation tasks in medical image analysis. Complex structures and a limited number of training samples can, however, result in the failure to capture the complete range of shape variations. Various modifications to the point distribution model (PDM) have been proposed to increase the flexibility of the model. Still model parameters are often determined...
Aimed at the current development of hydrological model and the Web GIS technology, the redesign of TopModel based on Web Service under B/S Architecture was put forward. The main technology related to the development of system, the functions of system and the architecture of system was discussed detailed, and this system was named DotTopModel. At last, the DotTopModel based on Web Service was realized...
In order to study the capacity of vehicles at conflict points in intersections, and to obtain the passing flow rate of the two conflict streams, this paper provides an in-depth analysis of the dynamic characteristics of vehicles at the conflict points, as well as the two major parameters - the time headway and the critical gap. Microscopic simulation is used to achieve qualitative analysis of the...
Wireless sensor network is becoming increasingly important in applications such as environmental monitoring and traffic control. They collect a large amount of sensor data, e.g., temperature and pressure. Nearby sensor nodes monitoring an environmental feature typically measure correlated values. In this paper, we propose a new location-aware-based data clustering (LABDC) algorithm to analyze the...
On the basis of experimental data about carbon material binder modification additives, the bond strength prediction model of the carbon material with RBF NN (radial basis function neural network) is studied. An improved hybrid algorithm of nearest neighbor clustering algorithm (NNCA) and mode 2 decreasing gradient descent (M2DGD) is proposed to solve the low accuracy problem of NNCA. Then the prediction...
