Because it is hard to depict real world traces, researchers proposed some mobility models in the study of mobile ad-hoc networks. It is aware recently that some mobility models will lead to non-uniform node distribution, which decreases the credibility and validity of simulations. Many researchers reconsider the node distribution characteristic for random waypoint model and have gotten some valuable and quantitative results. But similar investigations on the random direction model (RD) in square region are still missing. We presented a detailed analysis to the probability behavior of RD model in square region. Numerical solutions of node distribution are obtained. It shows that node distribution probability is higher and higher as its location varies by the sequence of center, border, and corner. It is to say that the stationary node distribution of random direction model is non-uniform.

The friction coefficient identification of dry clutch is a precondition for precise model-based dry clutch control. Recursive Least Square with forgetting factors is adopted to identify the friction coefficient of dry clutch during vehicle starting-up process. Because the accuracy of the engine damp coefficient affects friction coefficient identification of the clutch, it is necessary to identify the clutch friction coefficient and engine damp coefficient simultaneously. Through model simulation, it is shown that accurate and fast identification can be achieved no matter what initial values were chosen. It is also verified that the identification performance is good enough for different launch maneuvers with different throttle operations.

This article proposes an efficient and reliable communication mechanism of mobile Agent based on the current communication mechanism of mobile Agent to combine mobile Agent name resolution mechanism with message transfer mechanism. The communication component of the domain server and mobile Agent system are combined to realize the mobile Agent communication. The message processing uses the message storage and transfer mechanism based on the e-mail and the buffer pool processing, message transfer status and offline transfer in mobile Agent. In the Agent message and email migration we need check whether the message is timeout or not and its priority status. When deleting overtime message, give priority to the implementation of high priority message. This mechanism improves the communication efficiency of mobile Agent, solves the communication failure of mobile Agent problems, ensure the stability of the system and realize a distributed communication mechanism.

The difficulties of aircraft type recognition methods are introduced and the necessity of multi-classifier fusion decision method is discussed. The some kinds of invariants: Hu moments, Affine moments, Zernike moments, Wavelet moments, are used for constructing four SVM classifiers. Based on the above four classifiers, an adaptive-weight regularization method is proposed for improving aircraft type classification performance. Experiments are shown that, the recognition rate by the proposed method in this paper is better than any classifier of the above four classifiers, the fixed-weight multi-classifier fusion method and the majority multi-classifier fusion method.

This paper is concerned with the finite-time stabilization for a class of linear systems subject to actuator fault using limited information. A sufficient condition is derived which reveals the relationship among the sampling period, the norm of the transition matrix of the open-loop system over one sampling period, the input matrix, the feedback gain and the vertex set of the actuator fault to achieve finite-time stability of the closed-loop systems. An example is given to illustrate the theoretical result.

This paper concerns the finite-time stabilization of discrete Markov jumps systems (MJSs) with partly known transition probabilities (TPs) which are allowed to be known, uncertain with known lower and upper bounds and completely unknown. Combining the property of TPs, sufficient conditions are developed to guarantee that the system states do not exceed a certain threshold in mean-square sense during a specified time interval. It is shown that the method proposed in this paper is less or at least the same conservative than the existing result. Numerical examples are further given to demonstrate the effectiveness of the proposed method.

This paper concerns with the dynamics of TH equations both in the time domain and in the true anomaly domain. Based on the homogeneous solutions of TH equations, a state transition matrix for the TH equations in the true anomaly domain is obtained. The state transition matrix applies to any eccentric orbit. Through the state transition matrix, the sampleddata descriptions are obtained for both the TH equations and the dimensionless equations. In order to evaluate the sampleddata description presented in this paper, a discrete time model constructed by the state transition matrix derived by Melton is introduced. At last simulations present the errors between these sampled-data descriptions.

In this paper, a new method for music symbol classification named Combined Neural Network (CNN) is proposed. Tests are conducted on more than 9000 music symbols from both real and scanned music sheets, which show that the proposed technique offers superior classification capability. At the same time, the performance of the new network is compared with the single Neural Network (NN) classifier using the same music scores. The average classification accuracy increased more than ten percent, reaching 98.82%.

A SINS/CNS/GNSS integrated navigation scheme is researched for advanced upper stage in this paper. First of all, the composition of the integrated navigation is introduced. Then, the error model of the integration system in launch inertial frame was established. especially the misalignments of star tracker are inputted as system states, and also the federated filter algorithm is used to estimate the state errors of the integrated navigation system. Finally, simulations results show that the SINS/CNS/GNSS integrated navigation can provide navigation parameters with high accuracy, which can meet the accuracy requirements of advanced upper stage.
