Computer aided detection and diagnosis system (CAD) is designed to improve the efficiency and quality of medical diagnosis. The existing CAD system tries to realize a diagnosis process in an automatic way to replace the doctor’s diagnosis work completely, but it is difficult to capture the doctor’s detection and diagnosis needs and goals accurately due to lack of doctor’s experience. Thus, the accuracy...
In this paper, we studied the statistical features of user posting behavior in microblog. The number of statuses exhibits a double power-law distribution and there is strong positive correlation between the number of forwarding and comments. According to the empirical analysis of user behavior in both group level and individual level respectively, we find the interval distribution of user posting...
Based on a sample of 218 first-line service staffs from hotel industry, this study explored the dimensions of Internal Service Quality (ISQ) and examined their relationships with employee work satisfaction, organizational commitment and work engagement. Results showed that the ISQ contains of two dimensions, namely environment quality and interactive quality. Environment quality had significant and...
In this paper, we present a novel electrical test structure for determining the thermal expansion coefficients (TECs) of micromachined polysilicon thin films. The electrothermal properties of the test structure are analyzed. The pull-in method is exploited in characterizing TECs of thin films. In addition, an analytical model and a measurement method are developed. The finite element software ANSYS...
A method to simulate the dynamics of public opinion formation with pheromone is proposed. It is assumed that an individual would sense and deposit pheromone during its opinion formation, and it changes and updates opinion basing on the transition probability determined by the distribution of pheromone. Using the proposed model, simulations with several sets of parameters are carried out. The results...
In this paper, with dynamics analysis on whole vehicle and hydraulic retarder, the dynamic simulation model of engine and hydraulic retarder continual braking on sloping hillside of tracked vehicle is built by using Simulink software. The simulation results show that when engine and hydraulic retarder continual braking is used opportunely, it can meet the demands for tracked vehicles to safely travel...
