The network of public opinion has reflected more and more influence to government and society. A new multi-indicator grey target decision model with the positive and negative bull's-eye is studied. We propose the method and its algorithmic steps, then evaluate and rank the influence of the network public opinions, by the number of news and microblogging messages. © 2015 IEEE.

To find a new algorithm for non-invasively detecting ankle brachial index (ABI) by synchronous acquisition of four limbs pulse wave signals and cuff pressure-wave signals based on waveform character method and amplitude coefficient method in priority rule. The turning point was judged in certain range by calculating the difference of adjoining pulse waves and their relative ratio based on priority rule. The method settled the problem of misjudgement of the turning point before systolic blood pressure (SBP) and around average pressure. Many cases analyses and lots of clinical tests proved the algorithm effective and reliable. ABI is a handy and dependable predictor of atherosclerosis; it is associated with conventional risk factors such as age, blood pressure, and so on. © 2013 Springer-Verlag.

More and more tower crane accidents happened these years. It's necessary to development a system to ensure the operation safety of tower crane. Such a system was designed based on 51 serial MCU. Its functions include lifting weight detection, processing and output controlling. Additional functions such as password setting, standard weight setting, and power down detection and USB data reading are included also. Through the definitions of effective weight and normal/abnormal weight wave, a lifting weight calculation model was proposed clearly. Such a system is cheaper and functional. © 2013 Springer-Verlag.

This paper presents a novel grey clustering evaluation method based on standard triangular whitenization weight function by comparing the existing two types of triangular whitenization weight functions. We employ the new method to evaluate quality of human resources in recruitment for one college. The result shows that the new method provides improvement over the traditional methods on model simplification and universal application. © 2013 IEEE.

Internet mass incidents have become an important issue in China. To evaluate the scale of Internet mass incidents, we can collect the data of views, posts and replies in some typical websites such as BBS, Microblog and SNS, etc. However, different website takes different importance in transmission of internet mass incidents. The existing research usually sums the data of posts and replies of websites without considering the weight of different websites. This paper applies Analytic Hierarchy Process (AHP) to determine the weights of websites and evaluates the scale of internet mass incidents based on the weight grey target decision model. The results show that the method of weight grey target can achieve a more reasonable sort result by considering the weights of websites. © 2013 IEEE.

In this paper, an adaptive RBF network controller is devewloped for a class of uncertain system of dual arm robot. RBF neural network is employed to estimate the unknown continuous functions. The tracking error is proved to be bounded and ultimately converges to an adequately compact set. The results indicate that the proposed controller has satisfying tracking performance. © (2013) Trans Tech Publications, Switzerland.

Arterial stiffness is a very important physical parameter and the measurement to it is very important in clinic. This paper describes the principle and arithmetic of arterial stiffness index. The measuring algorithm based on oscillometric method is also discussed. The algorithm proves effective and reliable through the analysis of many cases and doing lots of clinical tests, it has been developed software under LabVIEW7.0 and applied in the hospital. Furthermore, it can give the information of the measurer's arterial stiffness and provide reference to doctor to determine the measurer's cirrhosis level. © (2012) Trans Tech Publications.

With the development of Chinese stock market, its stock data analysis becomes more and more important. Based on the analysis of Apriori, an improved Apriori algorithm using cross linker structure called CL_Apriori is proposed. The cross linker structure shorted the length of the objects linked, so that it could reduce the algorithm's time cost. The cross linker structure didn't save the candidates of frequent itemset, so that it could reduce the algorithm's memory cost. The experiments illustrates that CL_Apriori algorithm's performances are comparable.

To build the tower crane monitoring system is so important because of the accidents increasing in construction industry. Utilizing lifting weight ring to detect the goods weight is a reasonable way in such a system. Ring size should be considered in the situation to lift different weight goods. Through the definitions of two rings of the smaller and the bigger, the detected weight curves are explored. Through the simulation of tower crane operation, lifting weight curves are obtained and analyzed in different stages of starting, transmitting and ending. The experiments demonstrated that different weight level of goods should select the different size ring, and the detected weight data has its own attributes in different stages. © (2013) Trans Tech Publications, Switzerland.

An audio signal acquisition and analysis system with low-cost and high performance was developed, taking LabVIEW as the software development platform and the computer sound card as hardware platform. This system is capable of audio signal acquisition, real time dynamic display, analysis processing, storage and display of audio signal. Practical application shows that this system not only has those advantages such as high-precision, stability, reliable performance and being easy-operated, but also can achieve common data-acquisition within the designed frequency range of the sound card. The signal acquisition technology based on the sound card, especially the technology combining with virtual instruments has broad prospects in the field of engineering test measurement and teaching practice. © (2012) Trans Tech Publications, Switzerland.
