In this paper we studied the relationship between social capital and organizational performance, and tried to confirm whether learning orientation is an important medi- variable. Through theory ...analysis, we built research framework and constructed Structural Equation Model, and then carried out an empirical research on 134 enterprises which come from the Peal River Delta, China.
In order to study the electromagnetic coupling law of a metal body with different form holes, the body model and electromagnetic field needed were set up by the electromagnetic emulation software ...FEKO. Data showed that: the electromagnetic wave near the source presented obvious reflection; the intensity of electric and magnetic field changed tempestuously at frequency of 700MHz, which was the resonance frequency of electromagnetic coupling; the intensity of the round hole coupling field in the experiment is higher than the square hole; obvious electromagnetic wave diffraction happended at a distance from the body; the vertical far field changed greatly, affected by the body reflection mainly; in z, y direction the internal electromagnetic fields had asymmetry nature as to the hole.
The radiation effect experiment to a complicated electronic system by using of GW ultra-wide band (UWB) radiation source has been carried out. In cases of opening or closing the door of device under ...test (DUT) , the responses of test points on combination No.04 and No.08 of DUT have been measured. The response characteristics of test points on combination No.02 have been tested at different orientations of antenna of EUT And spectrum analysis has been performed for response waveforms. The results have shown that the response voltage on internal circuits of EUT may reach about 1.6 kV at condition of opening door of DUT when radiated by UWB source with 2.0 X 10 4 V/m of field strength (rise time is 0.3 ns and pulse width is 3~4 ns). The maximum response voltage on combination No.02 is about 1.6 kV under condition of optimum coupling of antenna. In this case, some of the electronic components which are sensitive to electromagnetic field may be damaged.
By proceeding from micro electromagnetic damage function of the device, combining with domestic and foreign research achievement on square wave EMP damage, the relation between the damage data of ...square wave and it of ESD EMP is analyzed. The dependence among the damage data of square wave and it of ESD EMP is setup tentatively. Then, the conversion among damage voltage of square wave and it of ESD EMP is finished.
One of the major drawbacks in block-based discrete cosine transform (BDCT) is the blocking artifacts at low bit rates. In this paper, an adaptive deblocking algorithm based on Markov random field ...(MRF) is proposed. A visibility function of blocking artifacts is introduced which based on human visual system (HVS), together with edge information to construct a new adaptive potential function of MRF. The experiment results show that the proposed algorithm reduces the blocking artifacts effectively and preserves the original edges faithful
This paper presents a novel original theory of artificial psychology based on artificial intelligence. We analyze human psychology comprehensively from the context of information science research ...methods, especially in regard to aspects of emotion, willingness, character, creativity and the realization of artificial machines. We also present tentative definition, purpose, rules, research content, application domain and algorithms, in order to establish an architecture for artificial psychology and promote artificial intelligence research to probe deeper into the human mind and so, to generate higher levels of development in the field.
This paper firstly analyzes the stability conditions of cascade brush-less doubly-fed induction machine(CBDIM) by means of the small signal linear model and Lyapunov theorem. Then the simulation ...including CBDIM, cyclo-converter, vector control system and the whole system experiment is done. Finally it draws a conclusion that CBDIM drives have the same performances as the DC drives and the simulation results are in excellent agreement with the experiment according to the experiment under the typical working condition. The CBDIM drives which is firstly developed in China makes a contribution to the wide application to some extent in variable-speed constant-frequency generators in the future.

A new gait recognition approach for human ID based on Fourier descriptors is presented in this paper. Body silhouettes are extracted by background subtraction, and cyclic gait analysis is performed ...to extract key frames. The body contours are processed by Fourier descriptors with data dimension being reduced, and templates are created. The recognition is achieved by nearest neighbor algorithm. We evaluate the proposed gait recognition method on the SOTON gait database, and the experimental results demonstrate that our approach has a good recognition performance.
