The recognition of the internal corners of a planar checkerboard calibration pattern image is very important to camera calibration. An effective approach is proposed to automatically recognize the internal corners of the planar checkerboard calibration pattern image based on the characteristics of local intensity and the grid line architecture of the planar checkerboard pattern image. The proposed procedure consists of the detection of image corners, the recognition of the corners at the intersections of black and white squares and the recognition of the corners at the intersections of two groups of grid lines. Experiments show that the proposed approach obviously reduces the time cost for camera calibration, speeds up calibration process and is especially adapted for automatic calibration based on multiple images.

The problem of non-fragile dissipative filtering for a class of nonlinear discrete-time systems with sector-bounded nonlinearities is investigated. The filter under study is subject to multiplicative gain variations, which are often encountered in practice and the sources of instability. It is worth pointing out that a more general type of filter gain variation is introduced. The purpose of the paper is to design a filter such that, for all admissible filter gain variations, the error filtering system is asymptotically stable and strictly (Q, S, R)-dissipative. A sufficient condition for the existence of such a filter is obtained by using appropriate Lyapunov function and linear matrix inequality (LMI) techniques. A numerical example is provided to demonstrate the effectiveness of the proposed designs.

This paper is concerned with the H∞ filtering problem for networked systems with multiple packet dropouts. A general model with multiple packet dropouts in multiple channels case is adopted to describe the data missing in the limited communication channels. A latest measurement data dependent Lyapunov function is proposed and exploited to develop a sufficient condition for the H∞ filter design in terms of a linear matrix inequality (LMI). The design guarantees the error system be exponentially mean-square stable and also achieve the prescribed H∞ disturbance attenuation level. A numerical example is given to illustrate the effectiveness of the proposed filter design method.

In QoS routing for wired networks, multiple path routing is popularly used. Because of excessive routing overhead, algorithms are not well suited for ad hoc networks. A Location-Based Multi-path Routing (LBMR) approach in Ad hoc is provided in this paper. This approach gets a shortest path by limiting the search for a new route to a smaller “request zone” of the ad hoc network (as in the LAR protocol) and uses intermediate nodes' location information to find another disjoint path by using Dijkstra's algorithm at destination node. Providing multiple routes helps to minimize route recovery process and to control message overhead. A per-packet allocation scheme is arranged to distribute data packets into two paths of active sessions. The results of simulation show that this routing method has good network performance with high packet delivery ratio, low control overload and low average end-to-end delay.

The conventional model of maintenance logistics is almost based on hierarchical structure, which exchanges information and shares resources depending on chain of control. It is not adaptive for requirement of sustaining all scope of operation and maintenance of equipments, and the research and development of an innovative maintenance model is necessary, which is evolved from chain-structure to networks-structure due to nonlinearity and complexity of maintenance support behavior. In this paper the organizational model and information model of maintenance support behavior are outlined, a topology structure of maintenance support networks is described, an approach to model maintenance logistics with three-level logistics architecture is presented using undirected unweighted networks, and then the performance metrics of complex logistics networks, such as average path length, clustering coefficient and degree distribution, is analyzed with Matlab based on adjacency matrix. Additional links between nodes of networks are evolved with small-world principle, and the performance metrics along with linkage probability are illustrated, which can be employed to optimize maintenance organizational and support networks.

This article considers the economic order quantity problem with imperfect items and service level constraint. We fuzzify the defective rate and annual demand to be the LR-fuzzy numbers and obtain the fuzzy total profit per unit time. The optimal order policy is determined using simple algebraic method and signed distance to maximize fuzzy total profit per unit time. Then, an algorithm which combined customer service level with optimal result obtained only from the aspect of maximize profit is provided to find the optimal order quantity in the fuzzy sense so that the required service level is attained and the total profit per unit time in the fuzzy sense has a maximize value. Furthermore, numerical examples are provided to illustrate the results of proposed model.

An indirect adaptive fuzzy control scheme is developed for a class of nonlinear discrete-time systems. In this scheme, the fuzzy logic systems are used to proximate unknown functions, and the unknown parameters are adjusted by time-varying dead-zone, which its size is adjusted adaptively with the estimated bounds on the approximation errors. The proposed design scheme guarantees that all the signals in the resulting closed-loop system are bounded, and the tracking error converges to a small neighborhood of the origin. Simulation results indicate the effectiveness of this scheme.

Logistics is divided into macroscopic logistics (also called social logistics) and microscopic logistics (also called enterprise logistics), according to microscope pattern and evolution line of TRIZ theory, this paper divides logistics into macroscopic logistics (social logistics), mesoscopic logistics (enterprise logistics) and microscopic logistics (individual logistics). we concentrate on microscopic logistics goods freight. We make use of integration pattern of evolution to integrate much single freight into super system. The selected technology is direct vehicular-customer communication (DV&CC) via radio transmission. It acts as intermediary in connection between vehicle and customer (v&c) in mobile ad hoc networks. In this way, we can make full use of nearby resource to meet customers' requirement at low cost, betimes and perfectly.

This paper considers the problem of robust generalized H2 filtering for discrete-time linear systems with polytopic uncertainties. Based on parameter-dependent Lyapunov functions combined with Finsler's lemma, new conditions for the solvability of the problem are given in terms of linear matrix inequalities (LMIs). Compared to the existing results, more slack variables are introduced to provide extra freedom for the generalized H2 optimization which lead to improving the performance and reducing the conservatism further. An example is give to illustrate the effectiveness of the proposed method.
