Base on field testing, the vibration intensity was increased by 28%, meanwhile, the noise was reduced by 4% and the impact vibration to foundation was reduced by 24% , which successfully solved the plugging screen problem and also verified the validity of the vibration isolation system.

Authors: Yan Xing Wei , Hu Jie Min , Zhang Jun , Wan Jian Wei
Published: September 2013

Image registration is widely used in applications for mapping one image to another. As it is often formulated as a point matching problem, in this paper, a novel method, called the Geometric Inference (GI) algorithm, is proposed for feature point based image registration. Firstly, according to affine distance invariant, the global geometric relationship between collinear correspondences is deduced and used for collinear point matching. Secondly, utilizing affine area invariant, geometric relationship between noncollinear correspondences is inferred and used for noncollinear point matching. Finally, the best affine transformation can be discovered from the correspondences composed of the collinear and noncollinear corresponding point pairs. Experiments on synthesized and real data demonstrate that GI is well-adapt to image registration as it is fast and robust to missing points, outliers, and noise.
Validation Criterion Functions for Geospatial Classification: A Case Study of Election Data
Authors: Wei Xiao Rui , Li Yang Ping
Published: September 2013

Classification on geospatial data is different from classical classification in that spatial context must be taken into account. In particular, the validation criterion functions should incorporate both classification accuracy and spatial accuracy. However, direct combination of the two accuracies is cumbersome, due to their different subjects and scales. To circumvent this difficulty, we develop two new criterion functions that indirectly incorporate spatial accuracy into classification accuracy-based functions. Next, we formally introduce a set of ideal properties that an appropriate criterion function should satisfy, giving a more meaningful interpretation to the relative significance coefficient in the weighted scheme. Finally, we compare the proposed new criterion functions with existing ones on a large data set for 1980 US presidential election.

Similar to the orthogonal frequency division multiple access (OFDMA) system, the carrier frequency offset (CFO) is a challenging problem in the single carrier frequency division multiple access (SC-FDMA) system, which can destroy the orthogonality among the subcarriers. As a consequence, multi-access interference (MAI) along with serious performance degradation will be induced. In this paper, a zero forcing (ZF)-based MAI cancellation scheme is proposed. Compared with other cancellation schemes, the proposed one mitigates the interferences in the time domain instead of the frequency domain. Simulation results show that the proposed method can significantly reduce the degradation and enhance the Bit Error Ratio (BER) performance.

In the paper, the region of the number of equilibrium points of every cell in cellular neural networks with negative slope activation function is considered by the relationship between parameters of cellular neural networks. Some conditions are obtained by using the relationship among connection weights. Depending on these sufficient conditions, inputs and outputs of a CNN, the regions of the values of parameters can be obtained. Some numerical simulations are presented to support the effectiveness of the theoretical analysis.
Mobile-Base-Station Location Privacy Based on Greedy Random Walk in WSN

Published: September 2013

As wide applications of wireless sensor networks, privacy concerns have emerged as the main obstacle to success. When wireless sensor networks are used to battlefield, the privacy about base-station-locations become a crux issue. If base-station location will be exposed to adversary, the consequence is inconceivable. Random data collection scheme has a problem that message latencies become larger higher for protecting mobile-base-station-location privacy. In this paper, GROW (Greedy Random Walk) is proposed to preserve mobile-base-station-location privacy. In GROW, data are forwarded and stored at pass nodes in the network, the base-station move in greedy random-walk to collect data from the local nodes occasionally, which prevents the attackers from predicting their locations and movements. Compared to random data collection scheme, GROW has smaller message latencies, while providing satisfactory mobile-base-station-location privacy.

By using of the principle of the reverse engineering and CATIA V5 software, the torque rheometer mixer rotor used in high polymer material test is designed. The POWERMILL software is used for NC programing and manufacturing simulation, the MIKRON UCP710 five axis linkage processing center is used for manufacturing. The practical application of this rotor on torque rheometer proves that this rotors structure design is reasonable. The test requirement of torque rheometer is well satisfied. This kind of rotor has a very good promotion value.

Cloud storage is a new extension and developed concept on the base of the cloud computing, aiming at providing data storage and transaction access service. On the base of the analysis of the basic concept of cloud storage, make the research and analysis on the safety of cloud storage. For the unauthorized access, data leakage, data access breakdown and other security problems, poses some security policies, including a challenge-response cloud storage identity authentication, encryption storage based on key associated with the username and a fast data recovery service which is parallel with data access. Hope cloud storage can provide a service of confidential, reliable and authentication.

Social networks provide customs with a platform for interaction and information sharing. In real social activities, whether individuals or businesses, have to rely on some relations to live, work or engage in commercial activities. The formation of relationship between different actor clusters based on the same actor in real social networks is described in the paper. The relationships and their types as well as relationship attributes in real complex social networks are analyzed in details. An index calledQinshuduto represent the degree of closeness between two actors in real complex social networks is proposed and its computation model based on relationship types and attributes etc. are given. Case study shows thatQinshuduis a very reasonable and effective way for the use of complex social networks.

In recent years, with the rapid development of mobile communication technology, intelligent mobile terminal tendency is increasingly popular. People are stepping into the era of mobile networks. Information systems created for enterprise or individual gradually rely on mobile networks and mobile devices. Because the mobile network is often interrupted, data synchronization working on the mobile network is very difficult. We put forward a model of the data synchronization in mobile network. JSON and data compression with parallel processing are introduced into the model. Thus, the model has high efficiency. It was applied to a company's Warehouse Management System and solved the problem of data synchronization preferably.

Published: September 2013

The effect of the cavity design parameters on the integrated performance parameter net thrust of hypersonic vehicle was investigated by computer numerical simulation methods in this paper. The cavity design parameters include position value XL and length-to-depth ratio L/D. The research purpose of the paper is to develop ideas for the integrated design of hypersonic vehicle. The studied results show that the effect curve charts of the ratio L/D on net thrust are similar at variable cavity positions. The extreme value of net thrust is obtained at some value of L/D. The fuel mixture touch underside step of the combustor easily to cause eddy loss which make against combustion and lead to net thrust descend while the cavity locates down step in the combustor. While the position of cavity on more combustor back, the combustion process is not built completely and the gas is exhausted quickly, which induces the more net thrust loss.
