RS232 interface executes the role of Transportation and Communication, which has became the important interface between MCU of embedded system and peripheral equipment. Because RS232 mainly work in bottom of communication protocol, so it is important to protect the infrastructure of RS232. In test, pulse double electromagnetic is pulled into RS232 data transmission lines by coupling clamp, simulated differential-mode pulse voltage, basing on the test data, it will get the damaged mechanism of RS232 interface, meanwhile presenting the Logistic model of injected voltage pulse and probability of damage to the port interface, and getting the performance evaluation of RS232 interface, moreover estimating the voltage pulse range of upper and lower bounds at the port in the normal and damage state.

Human auditory has non-linear characteristics, while wavelet packet transform (WPT) has flexible analysis ability to time-frequency property so that it is more compatible to simulate the human auditory model. In this paper, human auditory model is analyzed, after which a new algorithm for speech enhancement using node-threshold wavelet packet transform based on bark-scaled decomposition is established, multi-resolution singular spectral entropy method is applied to estimate the node noise, and uses soft threshold to deal wavelet transform coefficient. The experiments show that this algorithm is valid on various noise conditions, especially for color noise and non-stationary noise conditions.

In Kriging interpolation, the types of variogram model are very finite, which make the variogram very difficult to describe the spatial distributional characteristics of true data. In order to overcome its shortage, an improved interpolation called support vector machine-Kriging interpolation (SVM-Kriging) was proposed in this paper. The SVM-Kriging uses least square support vector machine (LS-SVM) to fit the variogram, which neednpsilat select the basic variogram model and can directly get the optimal variogram of real interpolated field by using SVM to fit the variogram curve automatically. Based on GODAS data, by using the proposed SVM-Kriging and the general Kriging based on other traditional variogram models, the interpolation test was carried out and the interpolated results were analyzed contrastively. The test show that the variogram of SVM-Kriging can avoid the subjectivity of selecting the type of variogram models and the SVM-Kriging is better than the general Kriging based on other variogram model as a whole. Therefore, the SVM-Kriging is a good and adaptive interpolation method.

Image segmentation is the foundation of multi-flow high speed video analysis. Based on improved canny operator, we provide a method to bubble gas/liquid two-phase flow image segmentation, which takes the more gray distribution information into account, uses gauss sigma smooth filter to maintain edges and eliminate noise, then by non-maximum control of grads and lag-threshold process, the clear bubble edge image is obtained. The method is very effective for the analysis and recognition of bubble multi-flow.

Finding top K items in data streams means finding K items whose frequence are larger than other items in data streams. There are some methods to find most frequent K items in the whole data streams, but they can't be used in arbitrary time interval. This paper proposes a new method-MMF(K)_MS to find most frequent K items based on Hierarchical Synopsis. MMF(K)_MS supports query in arbitrary time interval through using HFVN framework with variable number of node in every layer and using Count Stretch data structure to maintain Synopsis in each layer. At Last, Proving MMF(K)_MS rational and available by experiment.

I2C bus and RS-232 serial port are the important data communication interfaces between the MCU of embedded system and the peripheral equipment. The embedded system performance will be affected under complex electromagnetic environment by the improper disposal to the interfaces, which results in the low speed and reliability. According to the speed matching problems in current embedded programming, the paper designed two kinds of buffers, the double buffers and cycle single buffer, which separately solved the problems of the speed improvement of I2C bus and the serial transmission reliability of RS-232. The result of the experiment shows that communications of I2C bus and RS-232 serial port under complex electromagnetic environment can be of speediness and stabilization, and the ideal goal has been obtained.

The collocation strength algorithms based on statistical models have many disadvantages,Thus this paper constructed an algorithm for collocation of relation word based on P/T system. The algorithm established a basic model for the collocation of a relation word based on P/T system. Number of transition was then applied to distinguish single-layer model which described simple complex sentence of Chinese from multi-layer model which described multiple complex sentence of Chinese. The decomposition of multi-layer model were further discussed. The feasibility and reliability of this algorithm was verified with the feasibility of the decomposition and invariance of the model. Finally, the algorithm stored the place and transition in the form of a linked list, and was described in C language. The conclusion shows that P/T system is indeed a suitable mathematical model to construct the algorithm.
