The bottom-up self-assembly fabrication process of nanoelectronic results in higher defect density. Furthermore, transient and permanent faults could also occur during operation due to the sensitivity. Thus, defect and fault tolerance techniques are urgently needed. In this paper, we propose a concept of diversity mapping and three corresponding algorithms for defect-tolerance logic mapping in nanoelectronic crossbar. As the results show, our algorithms can achieve several or ten times higher logic mapping success rates compared to the best recently published technique over a set of samples with various problem sizes, especially superior in large scale problems. What's more, our algorithms can offer a set of different mapping schemes as by-products which we can utilize for accelerating online self-repair from the faults.

In this paper, based on Lyapunov function method and stochastic analysis theory, the stability of a class of impulsive stochastic reaction diffusion differential equations is investigated and some new criteria are obtained ensuring the mean square stability of trivial solution. As an application, a class of semi-linear stochastic impulsive reaction diffusion differential equations has been discussed to show the effectiveness of our results. This work is ended with an illustrative example demonstrating the valid of the provided criterion.

In order to improve the accuracy of centroid localization,a modified localization algorithm is proposed. On the base of centroid Localization algorithm, the effect comes from distance between the nodes is considered. Node localization with a higher accuracy is realized by weighted centroid localization. It is proved that the method can decrease location error, and the accuracy of location increased as communication radius decreased by experiment.

This paper is concerned with the implementation of ZigBee based wireless sensor networks, which has been applied in our service robot intelligent space successfully. A simplified ZigBee stack is proposed and the primitives of simplified ZigBee based wireless sensor networks are illustrated, which reduces the stack, thus the storage, size and cost of the nodes was brought down. To show the functionality of the ZigBee based wireless sensor networks in service robot intelligent space, we describe some of the components in detail, such as environmental sensors for environmental perception, home devices controllers for device control, localization system for positioning and ceiling projector for mobile robot navigation. Finally, we conclude this paper and the direction of future research are given.

This paper proposes an image fusion scheme based on a hybrid representation of empirical mode decomposition (EMD) and contourlet transform (CT), named the EMD-CT decomposition. The EMD-CT decomposition consists of three stages: the EMD stage, the Laplacian pyramid stage, and the multidirection analysis stage. As a result, the proposed EMD-CT shares high adaptivity of the EMD while owning multidirection analysis of the CT. For image fusion, fusion rules are applied on the EMD-CT representations of input images to produce a composite representation. The fused image is obtained by inversely transforming the composite EMD-CT representation. Experimental results show that the proposed fusion algorithm is more effective than fusion algorithms based on individual EMD or CT, and produces high fusion quality, especially for images with rich directional features such as edges and contours.

Granger causality is one of the most popular measures to reveal causality influence of time series and has been widely applied in economics and neuroscience due to its simplicity and easy implementation. In this paper, we first introduce two key assumptions which are showed to be pre-required for defining Granger causality; that is, without the two assumptions, one cannot draw a conclusion that there is no real causality even if we derive zero Granger causality. We then discuss two cases for which Granger causality is zero but there exists real causality between two time series. Therefore, researchers must be caution in drawing any conclusion based on Granger causality value.
