To fabric defect detection of rapidity and accuracy, a new method for defect detection based on curve fitting is presented. Firstly, acquiring fabric images are processed with median filter. Then take the measures of curve fitting to the enhanced defect imagines. Finally, the edge detection was carried out to the fabric defect. Experimental results show that the algorithm can effectively suppress noise, the edges are clear and accurate, that this method improves the speed of the defect detection while keeping the accuracy of the defect detection.

Combining the existing theories with the limited measurement data, we propose a method of determining whether a meteor burst exists or not and getting the corresponding distribution rule of meteor burst arriving interval, and simulate the whole process with C++. We judge the type of the meteor and give statistic results of the times of meteor, and get the curve of the received signal power. Based on the above work, we set up a channel model using the measurement data. The probability density function of the received signal power generated by our model is similar to that of the actual measurement data.

Channel capacity formula of MIMO system before and after antenna selection is derived. A modified dynamic antenna selection algorithm is presented. This algorithm selects the optimal k antennas based on Water Pouring principle, then the selected k transmitting antennas are redistributed equal transmit power. To verify the algorithm, it is applied to full-rank and rank deficient channel. Numerical results show the algorithm could select the optimal antenna subset in the two cases in a high degree of accuracy without redundant computation time.

This paper implemented MBIST in a H.264/AVC video decoder chip, Neptune. Neptune has 1.5 million gates, 37 memory blocks. In need of testing, a complete design for test should be done. This paper mainly designed and implemented Memory BIST targeting the 34 RAM block, except the 3 ROM blocks. The design included building design flow, choosing algorithm, generating background data and BIST controller integration. By BIST controller reuse, circuit area was saved. Working mode simulation, test time analysis, fault coverage analysis, circuit performance evaluation were done. The result showed that the MBIST achieved 100% fault coverage by a 2.49% increase in chip area.

In this paper, the Markov Family Models, a kind of statistical Models was firstly introduced. Under the assumption that the probability of a word depends both on its own tag and previous word, but its own tag and previous word are independent if the word is known, we simplify the Markov Family Model and use for part-of-speech tagging successfully. Experimental results show that this part-of-speech tagging method based on Markov Family Model has greatly improved the precision comparing the conventional POS tagging method based on Hidden Markov Model under the same testing conditions. The Markov Family Model is also very useful in other natural language processing technologies such as word segmentation, statistical parsing, text-to-speech, optical character recognition, etc.

Three-dimensional fluorescence spectroscopy technology is often used to identify the kind of the mineral oil. The dimension of it is high which cause the characteristic of the oil style-book are difficult to be maintained by the simple formula. In this paper, the principal component analysis (PCA) is used to reduce the dimensions of the spectroscopy. The independent component analysis (ICA) is used to do the matrix decomposition from the perspective of independence to extract the main feature of the spectroscopy data processed by the PCA. The support vector machine (SVM) is used to assort the main characteristic root books which are abstracted by the ICA. The species identification of the mineral oil will be realized by it. The identification result is visualized by the parallel coordinate's graph. The experiment results show that it is effective to extract the main feature of the spectroscopy. The classify speed is greatly increased. The identification of the oils can be realized with high discrimination which is 99.12%.

High frequency surface wave radar can detect targets beyond the horizon. It needs long coherent integration time (CIT) to detect low speed targets, such as ships, in the environment with sea clutter. In order to improve the efficiency of the radar system, and avoid the Doppler broadening caused by long CIT, it is necessary to shorten coherent integration time. Modern spectrum estimation technique is adopted to extract Doppler information from HF radar echo signals. It can provide high resolution to realize ship detection in short CIT. The real data processing and analysis show that the autoregressive spectrum estimation technology is effective to detect low speed target in short CIT in high frequency surface wave radar.

Grid computing provides a high performance computing platform to solve larger scale applications by coordinating and sharing computational power, data storage and network resources across dynamic and geographically dispersed organizations. Scheduling onto the Grid is NP-complete, so there is no best scheduling algorithm for all grid computing systems. An alternative is to select an appropriate scheduling algorithm to use in a given grid environment because of the characteristics of the tasks, machines and network connectivity. Job scheduling is one of the key research area in grid computing. The goal of scheduling is to achieve highest possible system throughput and to match the application need with the available computing resources. Motivation of this study is to encourage and help the amateur researcher in the field of grid computing, so that they can understand easily the concept of scheduling and can contribute in developing more efficient and practical scheduling algorithm. This will benefit interested researchers to carry out further work in this thrust area of research.
