Firstly, through the analysis of the gyro static output data and preprocessing, the stationary time series gyro random error has obtained. Then established the gyro drift error model based on time series ARIMA, and test the applicability of the model through analysis of residual. Finally, through the establishment of the Kalman filter based on the model to filter out the gyro random drift, and the use of Allan variance analysis of the filtering results. The results show that the modeling and filtering method and can effectively reduce the atomic spin gyro random drift error, the angle random walk coefficient raised an order of magnitude compared with traditional ARMA modeling method, so as to effectively enhance the output accuracy of atomic spin gyro and stability of the system.","PeriodicalId":297617,"journal":{"name":"2016 10th International Conference on Sensing Technology (ICST)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122364879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the capillary force, the Nafion solution can fill the Nafion resin channels, and nanoporous junctions were created to generate ICP. To demonstrate the concentration ability of the device, we conducted the experiments with Rhodamine 6G (positively charged) and fluorescein sodium (negatively charged). As a result, the device is more appropriate to concentrate the negatively charged species with concentration up to 2-fold. For further application, the method is convenient and simple to achieve a high-throughput concentration flow and a higher preconcentration factor.","PeriodicalId":297617,"journal":{"name":"2016 10th International Conference on Sensing Technology (ICST)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115466657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First we review the chaotic circuit design methodology into three kinds of methods like blocks stickiness with 3-blocks, decreasing-or increasing-type, for root cause of period three implying chaos. Then two new chaotic circuits are designed and demonstrated in core features of 1L-1C plus 1 multiplier and 1 operational amplifier, and 2L-3C plus 1T-MOSFET. The phase diagrams and FFT spectrums of tested independent variables show that new circuits are chaotic with the greatest Lyapunov's Exponents more than zero.

Extraction of such transient components is crucially important for gear fault diagnosis. Sparse decomposition based on matching pursuit (MP) is one of the effective methods to extract the weak feature contaminated by strong background noise and has been extensively used for transient feature extraction. In this paper, a practical and effective method is proposed for MP based sparse representation, which is enhanced in terms of sparse dictionary construction and computational complexity of MP. A special wavelet basis matching with the transients is developed to construct the sparse dictionary for fault vibration signal. The inner product operation in MP is replaced by cross-correlation implemented by fast Fourier transform (FFT) to address the problem of enormous computational complexity of MP algorithm. Simulation study shows that the transient feature can be effectively extracted and the computational efficiency is essentially improved by the proposed method. Application in transient components extraction of gearbox vibration signal from an automotive gearbox shows that the proposed method can extract the fault feature effectively.","PeriodicalId":297617,"journal":{"name":"2016 10th International Conference on Sensing Technology (ICST)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124206679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this approach can not accurately calculate fractal dimension of image which have smaller gray level. In response to the issue, this paper proposes an improved differential box-counting method on the height h' of box. In order to verify the superiority of the improved algorithm, DBC, RDBC, SDBC and improved DBC are separately utilized to estimate fractal dimensions of random images with different gray levels and texture image with different sizes, and then to compare. Experimental results demonstrate that: improved differential box-counting approach is more stable for random images with different gray levels.","PeriodicalId":297617,"journal":{"name":"2016 10th International Conference on Sensing Technology (ICST)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133545670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its precision is greatly influenced by the coil and reflector parameters. It is important to analyze and optimize those parameters so as to improve the precision. Therefore, it is necessary to make further research on how the sensor nonlinear error is influenced by parameters, such as reflector size, shape and coil turns, so that the sensor can be tuned for more high precision occasions. Models of the coil and reflector of the grating eddy current sensor are established with finite elements method (Maxwell software) in this paper. Reflectors with different size and shape and coils with different turns are simulated and calculated. The analytical results demonstrate that the coil turns should be as many as possible and reflector with semicircular on both sides is better. Besides, the optimal reflector length (the length corresponding to the smallest nonlinear error) has a linear relationship with coil width and length. The research has provided a guide to set reasonable parameters of coil and reflector to improve the precision.","PeriodicalId":297617,"journal":{"name":"2016 10th International Conference on Sensing Technology (ICST)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127658776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
