A method to structure the Jones quaternion utilizing Pauli matrices is proposed, improving the quaternion theory of polarization optics. It is proved that the Stokes quaternion is the double product of the Jones quaternion and its Hermitian transpose and that the rotation axis of the output three-adjacent-point Stokes quaternions is a mapping from the rotation axis of the three-adjacent-reflection-point...
The crosstalk caused by fiber nonlinear polarization rotation in Dual-Polarization QPSK (DP-QPSK) system is analyzed, and 100Gbps system is simulated. The results show that the one channel will produce a crosstalk and a ghosting in constellation to another channel, and the rotated angle of crosstalk constellation is proportional to the intensity of influencing signal. When the total input power is...
The college office as school comprehensive management organization, and its management level directly related to the normal operation of the school each work. Effective psychological contract management can increase the sense of belonging to the organization staff, improve work enthusiasm. This article mainly from the psychological contract theory, Pertinently discusses the connotation and characteristics...
In order to test and evaluate the influence of split share structure reform, an event study model is used in this paper. By introducing the unique characteristics of Chinese split share structure and the reform on 29th April, 2005, the CAR (cumulative abnormal returns) model can rationally explain the positive and negative effects of the reform around and after announcement. This paper provides the...
This paper proposes and designs a novel human vital signals monitor system based on wireless sensor network. It can realize the real-time measurement of multi-points and multi-signals at the same time. This system adopts RF controller CC2510 as the control core and SimpliciTI protocol to set up wireless network. After gathering the signals of temperature, heart rate and blood pressure, the terminal...
The fingerprint matching methods based on minutia has its drawbacks. Combined with minutiae and local neighbor flow pattern of the ridge, we proposed local bending potential energy around minutia as an important feature for alignment and matching. It is effective to align the direction of core point accurately. This feature achieves better alignment of local bending energy and was integrated into...
Economic and information globalization is the development megatrend of the world. Central Committee of the Party proposed clearly, the e-government is the focus of the national information work as for a time, the Government first, driving informatization in the national economy and social development. Comprehensively use of information technology to promote and improve the relationship between the...
With the economic and social development, Society for talents demand increased, Education undertaking in the status of national construction also is rising ceaselessly. Secretarial work in colleges teaching management role increasingly. How to plan better college secretary professional career, make them better play a role for vast practitioners, it is of vital importance. This article mainly researches...
Traffic sign detection plays an important role in a traffic sign recognition system. It is also an unsolved problem in the Intelligence Transportation System. Two main technique routes are typically used in current research of the traffic sign detection: the technique using gray-level object image or that using color object image. The former has the advantage that the related theories and methods...

It is known that the key factor affecting recognition rate of traffic sign is the color distortion caused by the color complexity. By analyzing the color characteristics and classification features of traffic signs, this paper proposes a novel model of the traffic sign classification method using color standardization based on the rule of "simplifying the problem, using the color information...
Support vector machine (SVM) is a novel machine learning method based on statistical learning theory, which can avoid over-fitting and provide good generalization performance. In this research, multi-category SVMs (M-SVMs) is applied to traffic sign recognition and is compared with BP algorithm, which has been commonly used in neural network. 116 Chinese ideal signs and 23 Japanese signs are first...
This paper presents a BiCMOS bandgap reference design, which possesses two Brokaw bandgap references with an RC filter at the output stage. Then a good temperature characteristic and a high power supply rejection ratio (PSRR), suit for a wide range of frequency, can be obtained. The simulation results show that within the frequency range from 100Hz to 10MHz, the design has achieved an average of PSRR...
