In the recent years, power line communication technology has seen a rapid development. However, due to the unsteadiness of the power line channels, there are still some problems of obstruction and attenuation in this field which decrease the prospect and scope of this technology. This paper which is based on previous basic studies about spread spectrum communication and OFDM (orthogonal frequency-division multiplexing) investigates the methods of using OFDM to restrain the obstruction and attenuation in low-voltage power line communications and give the systematic model based on the transfer characteristic of power line. Meanwhile the results of testing and simulation are presented which make power line communication technology more practical and applied.

The performance of lithium-ion rechargeable battery depends on its coulombic efficiency, which determines the measurement accuracy of the state of charge as well. In this context, the regularity that coulombic efficiency changes with environmental temperature and charge-discharge rate was analyzed in different cases, and a TPS (Thin Plate Spline) surface fitting-based coulombic efficiency estimation method was proposed for lithium-ion rechargeable battery. The presented method has a unique advantage in 3D smooth surface interpolation, which made it possible to model the functional relationship between battery coulombic efficiency, ambient temperature and charge-discharge rate, and then adjust the reconstructed precision with the plate rigidity sequentially. The experimental results illustrate that the proposed method is able to estimate the corresponding coulombic efficiency in the presumed range of ambient temperature and charge-discharge rate without battery cycling procedure. Furthermore, the accuracy and promptness of the novel method are verified simultaneously.

Aiming at the passive ranging to the non-cooperate target, the passive ranging algorithm based on the image sequence is proposed. The analysis on the image matching algorithms were performed, including SIFT, SURF, and ASURF. In which, the SURF algorithm is better method in our system becouse of the real time and precision. It can find plenty of special regions from the target images grabbed at real time. Each special region includes not only the position, size and direction of itself, but also includes a feature vector with shifting, rotation and scale invariance. According to that information, each special region in grabbed image can find a corresponding region in target features database, and build a matching pair. So, the ranging from the target to the camera can be estimated by the parameters of the matching pairs. Experimental results show that the passive ranging algorithm is effective and reliable.

In the field of milk quality testing, the technology of the ratio of scattered intensity to transmitted intensity has become a hot topic. In general, the particle size of fat globules after homogenizing is supposed to be the same. In fact, there is still the particle size distribution. The image processing technique is used for processing and analyzing the image of milk fat, in this paper. The results show that the particle size distribution exists in the homogenized milk fat solution. The results of calculating the radiation characteristics show that, the scattering properties and the attenuation properties have a significant change, and the absorption properties changes slightly, when fat particle size changes. And when the milk fat volume is 3.3%, the influence of absorption properties of light scattering properties can be ignored. When the wavelength is 1333nm, the scattering factor of the fat globules (D>3.0μm) will produce the largest deviation with 1.94. This paper will have important significance for calculating the scattering properties of milk fat.

In view of the widely used 1.55 μm coherent lidar for wind measurement, the theoretical analysis and numerical simulation is prepared. The theoretical analysis is made of four parts: the principle of wind measurement lidar, laser transmitter, the atmospheric transmission and signal processing. At the same time, the modeling of those parts and a numerical simulation are performed by MATLAB and Simulink. Results of a simple demonstration experiment coincide with those from the models, the coherent heterodyne signal can be clearly detected. Through the reverse calculation of peak of the simulation spectrum, the result accords with the given wind speed.

Face recognition involves artificial intelligence, pattern recognition, image processing, psychology and other fields. It is a critical research topic in human interaction. The facial expression recognition based on dynamic image sequence is becoming more attractive with the improvement of the computer speed. It is different between the facial expression recognition based on the dynamic image sequence and the facial expression recognition based on static image. More dynamic and static feature information is involved in the dynamic features. Expression feature extraction describes by static information and the changed trend of expression due to the collection of multiple images. This paper provides the dynamic feature extraction algorithm based on Candide-3 face model parameters to extract the dynamic feature with matching facial model.

The task partition algorithm is the key issues in distributed crowd simulation. To overcome low execution performance of existing task partition methods, we proposed a partition algorithm based on grid and graph partition. Firstly, the virtual environment is partitioned by uniform grid, gpu threads are introduced to accelerating the calculation. Later, all pairs of neighbor cells of the grid are connected with an edge. Then a connected graph is constructed, the cells are set as vertexes and the edges connect the cells. Finally, the connected graph is split by k-way partition method for task assignment. The experiments prove that the coarser-grained method can provide higher performance than existing algorithms for different population distribution while keeping low cost. Also the max imbalance rate can be kept very low.

The optimal control of reactive power and voltage is one of the essential issues in power system's secure and economical operation. After analyzing the model of reactive power optimization in regional power grids and the mechanism of particle swarm algorithm, this paper has proposed an improved discrete PSO algorithm with dynamic parameters and a diversion strategy to solve ORP problem in regional power networks. Compared with several other algorithms, the simulation results of tests on IEEE 30 bus system and an actual regional network indicates that the improved algorithm is more efficient and attains better voltage profile and less active power loss.
