Objective: To analyze the component law of Chinese medicines for knee osteoarthritis, and develop new prescriptions for knee osteoarthritis through unsupervised data mining methods. Methods: Chinese medicine recipes for knee osteoarthritis were collected and recorded in the database, and then the correlation coefficient between herbs, core combinations of herbs and new prescriptions were analyzed...
In the numerically controlled manufacturing process of the spring, there are some problems such as lower automation and inconvenient operation. In view of this situation, the paper presents the approach of digital manufacturing for spring. The composition and the key technology of the digital manufacturing system are revealed, and an example is given to illustrate the system application. The digital...
Social security system which is a necessary means to retain social stability and economic development is an important sign of modern nations and society with civilization. Firstly, this paper analyses the relations among the sub indexes of development level for social security systems. Secondly, it sets up differential equations model to quantitatively analyze the relations among the sub indexes based...
This article tests the information flow between Share A and share H adopting the common actor contribution method, which belongs to the price-discovery theory. We discover that in bear market information flow is lower relative to that in bull market. In bear market, information flow between closing price of share A and share H is largely the same as that of closing price of share H and opening price...
Quickly acquiring the data required from network node environments to share files in the vast P2P network environment is a challenging job. Many researches have proposed data sharing mechanisms and scheduling methods in P2P environments, however, most focused on the efficient utilization of network bandwidth, using greedy methods to deliver the data to the client end as early as possible. However,...
The main purpose of this paper is to predict stream-way transition with adaptive-network-based fuzzy inference system (ANFIS). Therefore, the downstream stream-way transition according to the upstream conditions is forecasted by ANFIS. Five main factors may affect the stream-way transition include inflow position, inflow angle, slope, flow discharge, and sand content of suspended sediment. We selected...
A new method for evaluating roundness error using polar measurement data, which named as polar mesh searching algorithm (PMSA), has been presented in this paper. The principle of the algorithm was that series of polar-coordinate mesh points were collocated around the periphery of the least square circle according to certain rule, the radius of all the measured points were calculated by regarding each...
Calcined layered double hydroxides particles were used as adsorbent to remove fluoride ions. Batch adsorption studies were conducted under various equilibrating conditions. The results show that the HTlc calcined at 500??C had the highest capacity of removal of fluoride ions, after adsorption it regenerated to its original layered structure, it is called "memory effect". In field water studies,...
With the rapid development of industry and agriculture, there are thousands of tons phosphate and nitrogen releasing into surface water. Phosphate becomes the main reason for eutrophication, resulting in deterioration of water quality. Ferric sludge from drinking waterworks was found to possess potential efficiency to remove phosphate ions from aqueous solutions. The maximum phosphate ions adsorption...
A diagnosis method based on integrated information fusion which combining neural network and Dempster-Shafer evidential theory is presented in this paper. In the method, vibration-testing data of hydropower units is processed through several sub-neural networks and the output result of each sub-neural network is used as the corresponding BPA (basic probability assignment) function that is hard extremely...
It is suggested in this paper to denoise the ultrasonic inspection signals using wavelet transform. The theoretic base is that wavelet transform is a band-pass filter. Firstly, the frequencies of the inspection signal are evaluated according to the excited signal. Secondly, an appropriate scale for wavelet transform is computed following the laws between the scale and the frequency. Thirdly, wavelet...
We present an algorithm to automatically extract skeletons for branched volumes by shape decomposition. First, a region growing strategy is adopted based on a distance transformation to decompose a volume into several meaningful components with simple topological structures. Then, the skeleton of each component is individually extracted. Finally, the skeletons of all the components are integrated...
