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.

integration of Geographical Information System (GIS) and Remote Sensing (RS) methods is one of the most important methods for detecting LULC's change. In this study, with the support of GIS, RS technology and based on recent 10 years LULC data, the landscape pattern dynamics and regional spatio-temporal features related with the LULC change of three metropolis in Asian region, Zhangjiagang (China), Dehradun (India), and Hanoi (Vietnam) are analyzed. We mapping the LULC using supervised method with parallelepiped-maximum likelihood algorithm in ERDAS Imagine 9.1 of the study area based on three consecutive satellite images: Land sat TM, Land sat ETM+ and ASTER. The regional feature of the three cities illustrates different development direction, and the urbanization process of the cities was at different stages. Zhangjiagang was found at the highest stage of urbanization, and with the significant high per capita income level. Hanoi and Dehradun were demonstrated a moderate degree of urbanization and extensive land alternation of agricultural and non-used land to urban area. In Hanoi, Vietnam's capital city, urban agriculture is a longstanding feature, but rapid urban growth is leading to greater competition over land use. In Dehradun, urban areas increased from 96.15 ha to 150.23 ha while agricultural areas decreased from 91.59ha to 45.33ha from 2000-2009. Urban class showed an overall amount and extent of change from 28023 ha to 33215 ha while agricultural areas decrease from 45031 to 41173 during 2002-2010 in Zhangjiagang. As the result, the issue of low quality and security of food was concerned in these three areas. Government support has encouraged urban producers to modernize and invest in safer developing practices. However, in these cities, as indeed elsewhere, there is an urgent need to recognize the significance of sustainable development, agriculture and native forest area reservation in future planning strategies. This kind of strategies identifies key trends and underlying environmental and socio-economic factors, and considers the future sustainability of the practice.

In state-of-the-art ASR technology, audio and video (AV) information based speech recognition is one of key challenges to cope with noise problem. AV fusion is one of the robust approaches for ASR. The main issues of AV fusion is where and how to integrate the two modalities' information. To enhance the AV fusion performance the paper [1] has proposed the optimum reliability fusion (ORF) and applied the ORF to AV speaker identification. In this paper we adopt the ORF based fusion in AV based speech recognition and evaluate the performance improvement in that domain. The ORF's main idea is to introduce weighting factors in score-base reliability measure (SCRM) for solving the over- or under-estimation problem in SCRM calculation. Our AV speech recognition system is implemented for Korean digit recognition using SAMSUMG AV database. Experimental results show that ORF effectively reduce the relative error rate of 42.8% in comparison with the baseline system adopt the previous AV fusion scheme [2].

Based on the charge control theory, a accurate analytical model of I-V characteristics for AlGaN/GaN high electron mobility transistor (HEMT) is presented considering the relationship between self-heating effect and polarization, electron mobility, velocity saturation, conduction band discontinuity, doping concentration, channel temperature. The comparison between simulations and physical calculation shows a good agreement. The model is simple in calculations, suitable for design of microwave device and circuit.

In [1] the decision feedback equalizer (DFE) based on constant modulus algorithm (CMA) and decision directed (DD) adaptive algorithm was proposed. It has been proved that it is much more effective than the conventional DFEs such as DFE based on CMA and DFE based on DD. However when Doppler frequency shift occurs in the communication channel, which can result in carrier phase rotation, the decisions precision is very low which degrades the performance of these DFEs. Consequently based on the DFE in [1] a new DFE with phase-looked loop (PLL) is proposed. The PLL works in CMA part which can offer correct decision for DD, so the proposed method can obtain lower steady state MSE and compensate phase rotations. The efficiency of the method is proved by computer simulation.

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.
