The system achieves the measurement of gas density information mainly by demodulating the cavity length of EF- PI fiber optical sensor. There are many ways to achieve the demodulation of the cavity length. For shortcomings of the big intensity demodulation error and complex structure of phase demodulation, this paper proposes that BP neural net-work is used to locate the special peak points in normalized interference spectrum and combining the advantages of the unimodal and bimodal measurement achieves the demodulation of the cavity length. Through online simulation and actual measurement, the results show that the peak positioning technology based on BP neural network can not only achieve high-precision demodulation of the cavity length, but also achieve an absolute measurement of cavity length in large dynamic range.展开更多

The author does not agree with Joseph Needham’s view:“There can be little doubt that on the whole its action was powerfully inhibitory”, and the author thinks Buddhism took a positive promotion and influence on the development of science and technology in ancient China as a whole. There were four main ways of Chinese Buddhism influence on ancient science and technology:(1) The Buddhist scriptures actually contain a wealth of knowledge of science and technology;the eminent Buddhist monks introduced them into China through translation, therefore enriched contents of science and technology in ancient China.(2) Some knowledge of science and technology in ancient Indian and other districts got into China along with the spread of Buddhism.(3) Ancient Chinese Buddhists took part in science and technology practice actively at that time, and they had got a series of achievements in science and technology.(4) Being inspired and affected by Buddhist scientific knowledge, those non-Buddhist scientists had engaged in many created work in a further step, and made much contributions to development of science and technology. The doctrine of Buddhism was not a complete hindrance to the development of science and technology, and the result turned out contrary in many respects that it had promoted development of science and technology. In fact, Chinese Buddhism had made many important contributions in the fields of astronomy, mathematics, medicine, and so on.展开更多

To overcome this limitation,a new vehicle positioning method based on radio frequency identification( RFID) is proposed. First RFID base stations are divided into three categories using fuzzy technology,and then Chan algorithm is used to calculate three vehicles' positions,which are weighed to acquire vehicles' accurate position. This method can effectively overcome the problem that vehicle positioning accuracy is not high resulting from the factors such as ambient noise and base distribution when Chan algorithm is used. Experimental results show that the performance of the proposed method is superior to Chan algorithm and 2-step algorithm based on averaging method,which can satisfy the requirements of vehicle positioning in VANETs.展开更多

Because handover location technology is one kind of pattern matching based location technologies, offiine handovex location positioning is an essential problem to be studied for successfully matching mobile probes on GIS map. Offline handover location positioning method involves two stages, handover location positioning respectively via two weighted models and an optimized model based on the intermediate results obtained in the first stage. A preliminary field test is conducted on a stretch of freeway in the inner suburban region in Beijing, and performance evaluation results show that the proposed method is superior to standard least square model in location accuracy and location precision, which is an effective method of offline handover location positioning.展开更多
