Lineage tracing queries help to locate updated views quickly in data warehouse. Materialized views can improve the efficiency of the data lineage tracing and view maintenance. This paper, a method to select materialized views using Top-k query algorithm is presented. The selection is based on the query frequency, the view storage space and maintenance cost. Experimental results show that Top-k query algorithm has a better query performance than the Heuristic algorithm for lineage tracing query.

In order to solve the shortest path planning problem in the time-dependent road network, we proposed a landmark-oriented heuristic algorithm based on the dynamic shortest tree (DALT). Experimental results show that the DALT algorithm in dynamic scenarios, not only to ensure the robustness and accuracy of the query, but also get better query time. In addition, by comparison with the classical static shortest path algorithm, the DALT algorithm in the preprocessing time and query efficiency achieved better performance.

This paper proposes a new algorithm FIM_AIUA, which updates association rules with incremental transactions and minimum support changes simultaneously. The algorithm expands FIM algorithm and AIUA algorithm, improves the efficiency and corrects the mistakes of My_IUA algorithm. Moreover, it modifies FIM algorithm with a new argument and presents a new function fim_aiua_gen() that rewrites the function aiua_gen() of AIUA algorithm. Experiments with real transaction data of a supermarket show that our proposed algorithm FIM_AIUA is efficient and outperforms both My_IUA algorithm and Apriori algorithm.

Feature extraction is one of the most important technologies for underwater targets recognition. In the past few decades, a number of methods for feature extraction have been developed, and under certain conditions they can achieve high recognition rate. However, for complex environments, it is still difficult to improve the robustness of the recognition system, and new robust feature extraction methods are expectant. This paper presents a novel method of feature extraction based on the spectrogram of acoustic signals. The image moment features and image texture features are extracted and the algorithms of LDA, PCA and their combinations are used to select the effective features respectively. The experimental results show that, these selected image features can achieve high recognition rate.

This paper describes a Computer-Aided Diagnosis (CAD) system for automatic pulmonary nodules detection on serial CT scans based on shape features. The system recognizes nodules by 3D geometric information through the process of interpolation, segmentation, suspicious area searching and recognition. Firstly, the serial CT images are interpolated to equal scales in X, Y and Z dimensions, in order to recover the original 3D shape of nodules. Secondly, pretreatment is implemented to segment the lung parenchyma region. Thirdly, detect objects called regions of interest (ROIs) as potential nodules by threshold of gray level and region growing. Finally, distinguish ROIs to find real nodules using moment invariants. The experimental results from CT scans data sets demonstrate that the proposed method yields a good performance of nodule detection. The system recognizes all the nodules of the data sets with a reasonable false positive (FP) 1/serial scans.

In this paper, we study supervisory control of a nondeterministic systems -- probabilistic discrete event systems. As language equivalence is not an adequate notion of behavioral equivalence for some nondeterministic systems, here we use the finest known notion of equivalence: bisimulation equivalence. The design of a supervisor such that the controlled system is bisimilar to the specification is studied and a model theorem obtained, in which it shows that a supervisor exists if and only if it exists over a certain finite state space. Also, notions about state-controllability are introduced as part of a necessary and sufficient condition for the existence of the supervisor.

In this work, a temperature predictor has been designed and implemented based on different series of meteorological data. The prediction is built by an artificial neural network multilayer perceptron, using 5 samples as window size of meteorological data. Besides, the floating point algorithm was evaluated, reaching a mean square error of 0.35, meaning a variation of 0.28 Celsius degrees versus the real temperature. Different approaches will be applied in order to show our best proposal.
