The signal reconstruction problems of Compressed Sensing is equal to a nonsmooth optimization problem. Since the original signal is sparse, a new l 1 -Minimization reconstruction algorithm is proposed based on modified trust region method of nonsmooth optimization. The algorithm can also reconstruct signal in super-linear convergence rate. Simulation results show that the algorithm is robust in reconstructing the original signal.

Word sense disambiguation (WSD) is the hot and difficult issue in natural language processing. Feature selection is the major factor that influences WSD. Different disambiguation methods selected different characteristics. Because the word in the context influences the polysemous disambiguation results, we proposed the concept of scenario word. Scenario words play different roles when we use them to determine the meaning of polysemy. We divide scenario words into co-occurrence words, collocations and demonstratives. Through the experiment, we test the feasibility of the method.

Congestion of wireless sensor network will increase transmission delay, even cause serious data loss. Not only it has impact on data transmission and the quality of service, but also wastes energy and shortens the network lifetime. To address this challenge, a novel congestion control strategy is proposed for wireless sensor networks called CCBT (Congestion Control Based on Triangle module operator) that comprises three mechanisms: (i) congestion detection based on triangle module fusion operator, (ii) hop-by-hop congestion notification, (iii) distributed rate adjustment. The simulation results show that CCBT significantly improves the performance of data transmission such as queue delay and the number of packet retransmission. Also, CCBT achieves steady increasing throughput.

This paper presents two improved techniques to determine boundaries and depth from observed gravity or magnetic anomalies. The first technique is based on analysis of the largest curvature of the total horizontal gradient of the total magnetic field to determine boundaries. The second technique is based on analysis signal of the total gradient of the total magnetic field to estimate depth. The technique is just only to calculate the total gradient magnitude of gravity or magnetic anomalies, rather than two derivatives of the total gradient magnitude. It is a particularly useful transformation for reducing the effects of noise and increasing the coherency of solutions from model-independent functions. The techniques is shown to work successfully in models and yield excellent results in delineating magnetic contact edges and reasonable performance in producing depth estimates. A practical surveyed data of the South China Sea show good correlation with known structural features.

Unclassifiable audio data exists when the conventional SVM was utilized to make classification in the speaker identification. To overcome this problem, this paper proposes a novel hierarchical fuzzy speaker identification method based on fuzzy c-means (FCM) clustering and fuzzy support vector machine (FSVM). Two phases are employed to construct the proposed system. Firstly, the FCM clustering technique is utilized to partition the whole training dataset into several clusters which has its own cluster center. And then, FSVM is trained by the cluster centers to make final decision and process the unclassifiable data. Experiment results show that the proposed method heightens identification accuracy of system remarkablely compared with the baseline SVM speaker identification system.

As an effective method to improve the successful rate of marine oil and gas drilling, marine controlled-source electromagnetic method requires acquisition of many marine controlled-source electromagnetic receivers which record electromagnetic data on the same time axis. However, receiver works on the seabed where GPS signal is shielded and relatively constant temperatures, this will bring about a consequence that the land synchronization method could not be implemented. To get the marine receivers which are time synchronization, we combine the GPS and OCXO (Oven Controlled Crystal Oscillator), and then calculate time drift. This method makes time drift down minimum by time drift compensation between different receivers.

In order to extract cloud cover feature from ISCCP D2 dataset, a method of feature extraction using wavelet and statistics was used. This method concerned the characteristic of the cloud cover and the applications requirement, and combined the autocorrelation function, partial autocorrelation function with the wavelet method. We can get the conclusion from the features: (1) the features from wavelet analysis are more evident than the features from original series; (2) most of the cloud amount series in ISCCP D2 dataset are stationary series, and the autocorrelation functions (AF) and partial autocorrelation functions (PAF) shows there are diurnal cycle in these series. As a result, it is possible to establish ARIMA model to estimate the cloud amount for a small region in the world.

Encryption is often used to protect sensitive data in database applications. However the traditional database encryption schemes cannot well balance the tradeoff between security performance and efficiency because of the efficiency declining due to encryption, besides they did not solve the problem of storing multi-level encrypted elements within a database or a table, also they seldom focus on key management. This paper proposes a novel efficient database encryption scheme so as to solve the problems mentioned above.
