Chinese culture is an important force in the construction of “The Belt and Road Initiative”. But as a result of aging, backward means of repair and other reasons, the ancient books are facing the danger of destruction. This paper intends to take the ancient literature of ethnic minorities in Yunnan as an example, aiming to do the virtual digital protection of ancient books by introducing computer graphics, image processing, virtual reality, somatosensory recognition and other new technologies in the field of information. Firstly, the minority documents are collected by means of high definition photography or scanning to establish a 3D model database, the science, high precision and permanent preservation of endangered document resources will come true. Secondly, we can construct the digital protection technology network platform of the ancient books of minority nationality in Yunnan through the combined ways of building a front desk virtual scene by X3D language and building a background application system by JAVA language. Then, through the comprehensive application of Kinect and Leap Motion somatosensory recognition technology to achieve the multi-dimensional interaction between the user and the system, it can enhance operability. Finally, the ancient literature can be displayed more vivid, more realistic and more comprehensive through the network in a wide range, so that the ancient books can be out of the geographical restrictions to achieve resource sharing.

Under the influence of high voltage, UHV DC bushing will appears another complicated problem, which is the thermal insulation of the bushing. This paper has calculated the temperature distribution of the long term stable operation of the DC bushing under rated current. The gradient distribution of high voltage DC bushing in the radial temperature is obtained from the inside to the outside; The temperature present lowly in the end and highly in the middle which is in the axial direction, the maximum temperature appears near the top of conductive epoxy rods. And when the temperature of the insulation medium increases, it will seriously affect the resistivity value, which affect the bushing electric field distribution, and cause the insulation problem.

On the basis of the characteristics for the millimeter wave radar and infrared imaging composite seeker, an information fusion algorithm has been designed based on interactive multiple model particle filter for the radar and infrared composite seeker. The interactive multiple model is combined with the particle filter algorithm. In this algorithm, the sub-optimal filter of the interactive multiple model (IMM) has been replaced by the particle filter algorithm. And it has efficiently solved the tracking problem for the maneuvering target under the conditions which are nonlinear and non-Gaussian. The simulation results show that the interactive multiple model particle filter algorithm has higher performance than interactive multiple model algorithm based extended Kalman filter. And this algorithm can be very sensitive to the change of the target maneuvering and can effectively improve the target tracking accuracy.

The complexity and high insert loss of radio frequency (RF) front ends are main constrains in application of Multiple-Input Multiple-Output (MIMO) system, especially in large scale scenarios. As an attractive solution, the concept of switched parasitic array (SPA) was proposed to realize the same performance of MIMO system with single RF chain. To assess its feasibility and efficiency, in this paper, a systematic model based on SPA technique is built and simulated. Numerical results show great agreement with theory in aspect of bit-error-ratio (BER) and channel capacity.

In this paper, based on the electromagnetic properties of biological tissue in the gigahertz and terahertz frequency, we deduced the finite difference time domain (FDTD) algorithm for Debye media respectively. And in each of the two bands, two kinds of typical biological tissues were simulated. By comparing the cancer tissue with skin tissue, it can be drawn that the absorption rate of electromagnetic wave for cancer tissue is better than that of skin tissue. In addition, simulation experiments allow us to observe the propagation of electromagnetic waves in biological tissue, which can help researchers analyze and understand the theory of electromagnetic wave in cancer detection and treatment.

During the operation of high frequency inverter, the square wave output of inverter has a large parasitic oscillation due to the influence of the parasitic capacitance and wiring inductance of the power field effect transistor. This paper analyzes the generation mechanism of parasitic oscillation of the field effect transistor and uses Matlab/Simulink for parasitic oscillation's simulation, then the parasitic oscillation is superimposed in the ideal model of the inverter. Finally, the elimination of spurious oscillation in inverter's square wave output is realized by using the method of combining PI control with repetitive control.

Along with the development of EDFA, the high sensitivity of coherent detection is less attractive than it used to be. However, coherent detection has another advantage of high frequency selectivity, which is still important. In this paper, we investigate a coherent receiver with EDFA as a preamplifier, which has several advantages including relaxed LO power requirement. Numerical results show that the receiver with preamplifier is higher than that of the receiver without preamplifier when the power of LO is less than 10dBm. Besides, we emphatically analyze the background radiation, and find that the power penalty caused by background radiation is about 1.8dB at 1550nm.
