This work exhibits design and characteristic study of highly sensitive temperature sensors of long-period fiber gratings (LPFGs) in Ge–Sb–Se fibers. Temperature characterization of the designed LPFGs with different working modes, operating wavelengths, and surrounding refractive indices (SRI) were studied. Results showed that temperature sensitivity of the proposed Ge–Sb–Se LPFGs reached 0.5787 nm/...
Multivariate time series, which is a set of ordered observations for multiple variables, is pervasively generated in air condition, traffic, entertainment, etc. Echo State Network has shown promising performance for processing multivariate time series due to its ability to approximate sequential dynamics. However, the intrinsic relationships among time series have not been generally analyzed in the...
Bridge shape is the important indicator to estimate the safety of the bridge. A bridge shape measurement system based on fiber optic gyroscope is builded up to survey the continuous shape of bridge. This measurement system comprises angular velocity sensor, linear velocity sensor, position sensor and etc. The bridge shape survey using the leveling measurement and bridge continuous shape measurement...
The angular velocity data of Fiber-Optic Gyro (FOG) has been analyzed to locate the singularity by the wavelet transform (WT) method. By using WT analysis method to decompose and reconstruct the signal of pavement data collecting by the FOG, the different types of pavement singularities can be extracted. The experiments are conducted on different road surfaces. The experimental results show that the...
Failure analysis is carried out in an irregular way because failure occurred in different situations with different phenomena. Experiences are usually needed to do failure analysis. When a new failure case occurs, it is difficult to make an effective scheme to implement the failure analysis without experiences. To solve this problem, an analysis method based on reliability physics is proposed in this...
This paper solves the problem of the excessive memory footprint and the slow speed of parsing when using the DOM method to parse the XML data. As we know the current XML parsing technology is the key of XML research field and now there are a lot of XML parsers, their works plays a significant role in promoting XML parsing, but failed to achieve a good balance in the analysis of both time and memory...
Three kinds of chromatography materials with temperature response have been prepared, and they were characterized by IR and TGA. By using the three materials, we studied the separation performance of four different steroids under 5 different temperatures. The results showed that bigger grafting density would lead to shorter chain, lower temperature response and longer retention time. Thus, it is important...
In present study, three kinds of temperature-responsive chromatography materials with different graft densities under the same graft chain length were synthesized via Atom transfer radical polymerization (ATRP), and they were characterized by Infrared detection and Thermo gravimetric analysis (TGA). Furthermore, the influences of temperature and graft density on the separation performance of steroidal...
In present paper, a novel smoothing function method for nonlinear complementarity problems is proposed. Then the property of the function is discussed. And the conditions of convergences of this iteration algorithm are given, so that the reference conclusions are extended. Theory analysis and primary numerical results illustrate that this method is feasible and effective.
