Abstract: Mobile e-business, with a full use of its mobility, makes information exchange and commercial transaction anytime anywhere become possible. But in the transmission technology and terminal handling ability, there is a huge gap to the traditional e-commerce. According to the existing wireless network communication technology, this paper introduces a new communication control algorithm to the mobile e-commerce transmission control. This algorithm can adjust data sending time according to the user’s needs and the constant change in the wireless communication and channels status. In this way, it can reduce the number of redundant data and network energy consumption, and makes the fusion between network and technique under the time requirements become possible.

Abstract: This paper focused on the problem of imprecise categorization of software behavior data, using relative data mining techniques to find determined categorization of software trustworthiness which represents the consistency of software behavior and its claim. In detail, addressing to the measurement method of software trustworthiness mentioned above, this paper propose a new measurement framework for software trustworthiness based on imprecise categorization. We firstly define the formal representation of software trustworthiness according to its definition about imprecise categorization. Secondly, we introduce relative measurement framework about imprecise categorization and its application approaches in measurement for software trustworthiness. Finally, we make the conclusion of this paper and discuss some research area in software trustworthiness in future.

Abstract: Online mining of frequent closed itemsets over streaming data is one of the most important issues in mining data streams. In this paper, we proposed a novel sliding window based algorithm. The algorithm exploits lattice properties to limit the search to frequent close itemsets which share at least one item with the new transaction. Experiments results on synthetic datasets show that our proposed algorithm is both time and space efficient.

Abstract: A intelligent variable frequency amplitude reduction advance control system whose single-chip-microcomputer act as the core controller is built, and the vibration frequency curve with multiple wave variable sine increase and decrease periodic cycle is applied as the input frequency curve, which made the vibration mill have multiple frequency and amplitude. The control methods are studied, and the operation program is debugged. By using the sensor signal amplification, A/D conversion, on-line monitoring, data mining, and the forecast of the extreme value point of the vibration intensity and its distribution, and then by conducting the judgment, detection, correction and real-time feedback of constraint condition to achieve advance control of vibration intensity over-limit and over-time.

Abstract: Aiming at the problem that it’s hard to get the real construction information during the site management of high arch dam, this paper proposes the method of Unity3D-based three-dimensional (3D) dynamic interactive query of high arch dam construction information. Firstly this paper elaborates the basic theory of this method, and then adopts parametric modeling method to build the Unity3D-Based 3D virtual scene of high arch dam, combines with database technology and programming technology to realize the 3D dynamic interactive query of dam construction information. Finally this research is applied to the construction of a hydropower station high arch dam to build a system of 3D dynamic interactive query of dam construction information. This system achieves the real-time interactive query and analysis of arch dam construction information to provide technical support for site management scientifically.

Abstract: The electrostatic discharge (ESD) failure of power drain-extended MOS (DEMOS) devices, the protection circuit SCR, and a DEMOS with SCR protection circuit will be investigated in this paper. The ESD immunity of the DEMOS was very poor under the human-body model (HBM) testing. Here we discuss how to design an ESD good SCR device. Eventually, the ESD immunity of DEMOS test sample with an SCR circuit can significantly improve device ESD performance.

Abstract: Brand is a special, highly integrated value of the assets. It is also that companies dominate the market, a magic weapon to win in the competition. This paper starts from the analysis of the characteristics and limitations of the current brand valuation methods, analyzing the problems and the reasons of the website brand valuation, and making a description of the website brand value evaluation system. Finally this article puts forward the choice of strategy assessment methods.

Abstract: In this paper the network advertising player is introduced. It can update the contents conveniently. The Kind-Arm 6410 development board is used as the display of the player. In one PC, the HTTPD server is set and the control interface is set in another. Firstly, the user logs into the background web interface, chooses the files and sends to the server through the socket network. Then the file is sent to the development board by the server. On the board it is decoded by the mplayer and displayed on the screen.

Abstract: An improved resource limited artificial immune algorithm is proposed, which is applied to the incremental data clustering. The algorithm adopts an improved function of stimulation level, allowing the system to distributing resources more reasonably. And the algorithm introduces the immune response model, simulating the initial response and the secondary response. Through simulation experiments on the UCI data sets, and comparison with the artificial immune based influential incremental clustering algorithms, it shows that the algorithm is effective, can extract data characteristics, and increases the clustering accuracy and data compression rate.

Abstract: In this paper, the Schrödinger operator on n dimensions Euclid space with the non-zero, nonnegative potential function satisfying the reverse Hölder inequality is considered. The weighted boundedness of the commutators composed of several Riesz transforms associated with the Schrödinger operator and weighted Lipschitz function on weighted Lebesgue integral spaces are obtained, for some weighted function.
