Instant Messaging (IM) tools have been popularly spread over the campus in recent years due to its good interactivity for geographically distributed users. Many lecturers have chosen one of the IM tools as complementary means to improve their classroom teaching effects. In this paper, a number of issues we experienced are presented, including privacy concerns, trade-off between efficiency and fairness, and inside or outside classroom. Then, a model previously published for peer to-peer time-free learning is discussed. Finally, a result of teaching practice using IM tools is presented, which approves promising use of IM tools based on this model.

In order to model normal behaviors accurately and improve the performance of intrusion detection, a heuristic genetic neural network(HGNN) is presented. Feature selection, structure design and weight adaptation are evolved jointly in consideration of the interdependence of input features, network structure and connection weights. The penalty factors for the number of input nodes and hidden nodes are introduced into fitness function. The crossover operator based on generated subnet is adopted considering the relationship between genotype and phenotype. An adaptive mutation rate is applied, and the mutation type is selected heuristically from weight adaptation, node deletion and node addition. When the population is not evolved continuously for many generations, in order to jump from the local optima and extend the search space, the mutation rate will be increased and the mutation type will be changed. Experimental results with the KDD-99 dataset show that the HGNN achieves better detection performance in terms of detection rate and false positive rate.

In the human-machine systems impedance control and admittance control methods are wildly used. Impedance control is a dynamic mapping from motion to force and admittance control is a dynamic mapping from force to motion. In this paper, position-based impedance control system is constructed in human-vehicle interaction to adapt to human operation under unstructured environment. For predicting the desired impedance, a predictive fuzzy inference algorithm is purposed. Finally an experiment using driving simulator is set up to verify the effectiveness of constructed impedance control system.

In this paper, a new method for estimating multivariate density functions is proposed based on Support Vector Machine (SVM) technique and copulas. It is well-known that the SVM method can result in a sparse and accurate estimate of a density function, however, the knowledge of marginal densities of a multivariate density are not employed directly although they may be known in some applications such as multi-sensor systems. Benefitted from Sklar's theorem, in which a joint distribution function is characterized by its margins through a copula, the proposed approach can incorporate efficiently the knowledge of the margins and dependence structure of random samples into density estimation so that more accurate estimates are obtained. Some numerical examples are given to demonstrate that our approach can result in more accurate estimates than both direct SVM method and multivariate kernel density method based on copulas.

Wang et al. [6] proposed a scheme of allowing granter nodes to allocate multiple mini-slots to improve the data scheduling efficiency of the three-way handshake procedure, however, the size of the availability mini-slots is no considered. In fact, the available mini-slot space may not be contiguous but can include many windows of several slots in the actual data scheduling. To address this problem, we propose a novel data scheduling scheme, which is based on our proposed optimal model of mini-slots allocation, to reduce the number of mini-slot segments and to keep continuous mini-slots as long as possible. Simulation results show that our proposed scheduling schemes can achieve low transmission delay of data packets and high utilization ratio of mini-slots of all network nodes.

A new wavelength detection technology about fiber Bragg grating(FBG) is reported, which is combined with the wavelet analysis. It can be used in wavelength multiplexing techniques, which can increased the degree of automatic calculation and the objectivity. By using this method, the spectrum of light wave is obtained better, thus, the influence of the side lobe voltage is solved by this method in wave processing, also the calculation speed is improved. The results of the experiments show that reflective signature is reconstructed preferable, and in addition, the influence on of the real peak detection which is caused by the side lobe voltage is wiped off.

Mathematical model of the attitude control system of Flapping Wing Micro Aerial Vehicle(FWMAV) is presented, and a novel multi-variable Active Disturbance Rejection Control(ADRC) scheme is proposed. The design of attitude controller is challenging owing to the complex flight process. The heavy difficulty is that the system embodies uncertainties, nonlinearities, coupled multi-variableness, and all kinds of disturbances(such as gust). Because ADRC does not depend on the accurate mathematical model of plant, the disturbances and uncertainties are taken as one state matrix vector to design Extended State Observe (ESO) and nonlinear PD (proportional derivative)controller. The controlled attitude angles can reach the desired results simultaneously if the relevant parameters are tuned harmoniously. Simulation results are presented to verify the effectiveness of the proposed method.
