Extracting centerlines of coronary arteries is a challenging but important task in clinical applications of cardiac computed tomography angiography (CTA). In this paper, we propose an inertia-driven path tracking method based on the directional minimal path (DMP) to automatically extract the coronary centerlines. In DMP, the path tracing is divided into a number of segments. The proposed method adopts...
Originated in the 1970s, the theory of competence has become today's leading issue in the field of management and psychology. The current research interviewed 20 provincial grade and higher sports coaches relating to 8 sports events using the Behavior Events Interview (BEI) in Sichuan province, after which ldquoThe Competency Dictionary of Sports Coaches of Chinardquo was utilized to rate/code the...
This paper considers a continuous capacitated facility location problem without a priori knowledge of the desired number of facilities. The demand locations and volume are known to the decision maker. A new hybrid evolutionary algorithm combining variable-length GA (genetic algorithm) and PSO (particle swarm optimization) together is proposed to solve the problem. For variable-length GA, the chromosome...
Hardenability prediction is very difficult in the steel refining process. Based on the idea that the accuracy of model can be significantly improved by combining several sub-models, a multiple support vector machine(MSVM) based hardenability prediction model is proposed in this paper. The influence factors of hardenability are analysised to determines the number of sub-model and the input variables...
Fast verification of the prototype design on software radio platform has become one of the most important research topics in communication systems. Based on OFDM receiver which is implemented on FPGA, the paper focuses on many key issues in the implementation of the strategy in software wireless platform such as OFDM frame synchronization, frequency compensation, symbol timing, etc. The proposed corresponding...
