This paper presents an optical electric field sensor (OEFS) based on evanescent field characteristics of micro-nano fiber (MNF) and electro-optic effect of electro-optical polymer to solve the problem of large size, large influence on measuring field and low sensitivity in the traditional electric field sensors. The sensor body is fabricated using a MNF coating Special electro-optic polymer. In the...
A system and source joint estimation method for EM emission modeling is proposed in this paper. Based on the priori knowledge, i.e., the transfer function of system is smooth and the form of source signal was already known, the paper using joint estimation method to solve modeling problems when measured only the emission amplitude spectra at some ports. Experimental results verify the method could...
A developed phase differences interpolation algorithm in the correlative interferometer is proposed in this paper. Using the phase differences interpolation operation in the follow-up data processing, the improved method could reach a high precision while the process-time is acceptable. Simulation results show that this optimization method works well and has a much higher accuracy than traditional...
Being different from the previous studies, a comprehensive indicator system is constructed in this paper in order to reflect the influence the accounting information quality and corporate governance have on SVM model. This system includes financial indicators, the indicators of accounting information quality and those of corporate governance. Then taking Chinese listed companies of A-stock market...
