AUTOMATIC DETECTION AND RECOGNITION OF MAN-MADE OBJECTS IN HIGH RESOLUTION REMOTE SENSING IMAGES USING HIERARCHICAL SEMANTIC GRAPH MODEL
Objects detection Objects recognition High resolution remote sensing images Semantic graph model
2014/4/24
In this paper, we propose a hierarchical semantic graph model to detect and recognize man-made objects in high resolution remote sensing images automatically. Following the idea of part-based methods,...
Weights and degrees in a random graph model based on 3-interactions
Martingale random graph preferential attachment scale-free property
2012/6/19
In a random graph model based on 3-interactions we give the joint asymptotic distribution of weights and degrees and prove scale-free property for the model. Moreover, we determine the asymptotics of ...
Modeling Social Networks with Node Attributes using the Multiplicative Attribute Graph Model
Modeling Social Networks Node Multiplicative Attribute Graph Model
2011/9/15
Networks arising from social, technological and natural domains exhibit rich connectivity patterns and nodes in such networks are often labeled with attributes or features. We address the question of ...
The risk graph is one of the most popular methods used to determine the safety integrity level for safety instrumented functions. However, conventional risk graph as described in the IEC 61508 standar...
几何参数化计算的柴油机冷却风道键合图模型（Geometry Based Parametric Bond Graph Model of Diesel Cooling Fan-channel Analysis）
柴油机 冷却系统 风扇 流道
2009/9/2
为确定柴油机散热系统的空气流量及空气流速分布规律，以研究散热性能和风扇风道几何参数之间的关系，建立了风扇风道几何尺寸参数化计算的冷却风道键合图模型。通过分析风扇的尺寸和空气动力性能，应用键合图方法分析风扇风道的功率损失，建立了系统模型，系统模型参数均为元件几何参数及空气特性参数，提出了散热器出风口风速分布预测方程，实现了以风扇转速为输入的散热器风道的流量计算及出风口风速分布预测。样机的现场风速测量...
