Authors: Li Li Hui , Zhu Jia Rong
Published: August 2014

In order to ensure the reliable transmission of important data between the host computers in fields of industrial control based on Zigbee. We designed a reliable serial transmission mechanism. The core of the mechanism is as follows: first identified the data packet with a sequence number, if the receiving node received a data packet, then compared the sequence number in the data package with expected sequence number, and determined whether to receive the data package and sends it to the host computer. Three values of the variable represented three kinds of status respectively, namely, data has been successfully sent, received duplicate packet and serial port is busy. Receiving node returned status identifier and other information to sending node. According to the statuses of data has been successfully sent or received duplicate packet, sending node would set the send status to allow transmitting new data. As to the case serial port is busy, the sending node would resend the old data package later. Experimental results show that this system is stable and reliable, with good adaptability.

A Degree Distribution Optimization Algorithm in Unequal-Protected LT Code
Authors: Jiang Wei , Yang Jun Jie
Published: August 2014

LT code is the first practical implementation of digital fountain code. The coding behavior of LT code is mainly decided by the degree distribution which determines the relationship between source data and codeword. Since coding systems with unequal loss protection are widely applied, a degree distribution optimization algorithm is designed for unequal-protected LT code. The degree distribution that minimizes the number of un-recovered source symbols is found. By introducing the weighted cost, the optimal degree distribution can be solved by evolutionary strategy. The experimental results are quite promising. Compared with LT code with robust soliton distribution, the proposed algorithm improves the number of the recovered symbols obviously with the same overhead.

Published: August 2014

Modern cameras typically consist up to dozens of individual optical elements to compensate for geometric and chromatic aberrations. In recent year, high-quality single lens imaging has been proved possible by eliminating aberrations with computationally. Point spread function (PSF) calibration is key technique for single lens imaging. However, the existing PSF calibration method is time-consuming and has to be completely repeated for every new lens. This paper proposes a fast PSF calibration to accelerate the process. A PSF model is firstly estimated from a group of single lenses, which is close to the ideal PSF for specific tested single lenses. Then the PSF model is used as the iterative starting point in the calibration optimization. Experimental results show that this method can significantly improve the efficiency of PSF calibration process, and deconvolution performance is competitive with existing methods.

Authors: Liu Han , Tian Xiao Lin , Xu Ao Ao
Published: August 2014

A new algorithm of automatic extraction of multi-size lunar craters has been proposed. The proposed algorithm could detect multi-size craters by using different filters in multi-steps, which is a loop to detect multi-size craters by different size filters. In the first step, the new algorithm will use a larger filter to reduce noise and detect larger craters by using circle fitting at de-noised image. After marked these areas in the original image, it will remove those detected crater areas from the original image and do the noise reduction with a smaller filter again. The new algorithm will repeat the second step several times to finish the detection of whole image. Finally the new algorithm will merge results of these steps and output a final result. The new algorithm has been tested based on the Chang’E Data in the Matlab environment. The result has shown that this new algorithm does have the ability to detect different sized craters on the lunar surface, which has pointed a way to detect secondary craters automatically.

In this paper, an effective motion comparison method based on segmented multi-joint line graphs combined with the SIFT feature matching method is proposed. Firstly, the multi-joint 3D motion data are captured using the Kinect. Secondly, 3D motion data are normalized and distortion data are removed. Therefore, a 2D line graph can be obtained. Next, SIFT features of the 2D motion line graph are extracted. Finally, the line graphs are divided into several regions and then the comparison results can be calculated based on SIFT matching ratios between the tutor’s local line graph and the trainee’s local line graph. The experimental results show that the proposed method not only can easily deal with the several challenge problems in motion analysis, e.g., the problem of different rhythm of motions, the problem of a large amount of data, but also can provide detailed error correction cues.

Recurrence Characteristics Analysis of Near-Surface Wind Speed Signal with Different Sampling Frequencies
Authors: Zeng Ming , Wu Zhan Xie , Meng Qing Hao , Li Jing Hai , Ma Shu Gen
Published: August 2014

The wind is the main factor to influence the propagation of gas in the atmosphere. Therefore, the wind signal obtained by anemometer will provide us valuable clues for searching gas leakage sources. In this paper, the Recurrence Plot (RP) and Recurrence Quantification Analysis (RQA) are applied to analyze the influence of recurrence characteristics of the wind speed time series under the condition of the same place, the same time period and with the sampling frequency of 1hz, 2hz, 4.2hz, 5hz, 8.3hz, 12.5hz and 16.7hz respectively. Research results show that when the sampling frequency is higher than 5hz, the trends of recurrence nature of different groups are basically unchanged. However, when the sampling frequency is set below 5hz, the original trend of recurrence nature is destroyed, because the recurrence characteristic curves obtained using different sampling frequencies appear cross or overlapping phenomena. The above results indicate that the anemometer will not be able to fully capture the detailed information in wind field when its sampling frequency is lower than 5hz. The recurrence characteristics analysis of the wind speed signals provides an important basis for the optimal selection of anemometer.

Published: August 2014

According to the demands of the text recognition in natural scenes, we focus on the text recognition system and its algorithm. Firstly, we present a secondary detection method in which we locate the text area quickly by using the edge of these characters and secondly introduce an improved segmentation algorithm of active contour to detect the location of the target character accurately, based on prior knowledge. Lastly, in the state of text recognition, we propose a KNN (K-Nearest Neighbor) classification method using the descriptor of shape context. The experiments show that our algorithm could achieve better detection rate than others.

Published: August 2014

The precision of the altitude measurement system installed in some type airplane does not fulfill the need of the airborne equipment, this paper propose a method based on the federated filter which utilizes the data of the air data computer system (ADS), inertial navigation system (INS) and the GPS to improve the precision and stability of the altitude output. The results of simulation show that the algorithm takes full advantage of all of the sub-system, which reduces the error of the ADS and improves the altitude output precision. Meanwhile the method may separate some faulted sub-system (e.g. GPS) and reform the system, which renders the system better fault tolerant and real-time performance.

Attenuation coefficient is frequently-used for ultrasonic creep inspection in metals. However, in practical inspecting, e.g. thick wall weldment in high temperature pipings, it is usually difficult to measure the accurate propagating distance of ultrasound, which results in an inaccuracy of attenuation coefficient calculation. Therefore, a modified method for attenuation coefficient calculating was proposed here, in which the flight-time of ultrasound was substituted for propagating distance. The new calculated attenuation coefficient was named as flight-time-attenuation parameter, and had a unit as dB/us. A uniaxial tension creep experiment with pure lead was conducted to verify the detecting ability of this new parameter. Two piezoelectric wafers were pasted on the pure lead specimen, and ultrasonic testing was carried out simultaneously without interrupting the tension procedure. Attenuation coefficient and flight-time-attenuation parameter were calculated with inspecting signal acquired from creep specimen, and compared with each other. The results showed that two ultrasonic parameters had the same variation tendency along with creep procedure, and flight-time-attenuation parameter had a better sensitivity. Accordingly, the flight-time-attenuation parameter could be used for ultrasonic creep inspection in metals, and worked as a replacement of attenuation coefficient calculated with propagating distance. Another creep inspecting experiment with P91 steel weldments was conducted to verify the practicability of the new parameter, in which the new flight-time-attenuation parameter showed a good distinguishing ability for different creep status.
