Abstract: Planting roof technology as the main types of urban stereo greening，not only has the meaning of ecology, but also can improve the city landscape, rich architectural forms of efficacy. This paper will divide planting green roof technology into heavy planting roof and light planting roof, which are discussed respectively, in order to strengthen public understanding of planting roof technology.

Abstract: The architectural autonomy have different meanings in different contexts, this article attempts to read the architectural autonomy which reflected in the architecture of the city from multiple perspectives. As types of architecture is the core of a building, "type ", so this article analyze the meaning of types by it between the city and architecture , the culture and form, the initiative and presupposition, the rationality and sensibility, then ultimately it comes to the dialectical features of architectural autonomy.

Abstract: This article first introduces task-driven teaching approach, then analyzes the perplexity in software engineering teaching, and finally discusses, by giving an example, how to adopt task-driven teaching approach in software engineering teaching. Since software engineering is abstract and very practical, its learning will become an active process rather than passive one when task-driven teaching approach is adopted. Students can better grasp teaching contents and teaching effects can be greatly improved if they know the teaching tasks.

Abstract: Focusing on the wireless relay in heterogeneous wireless networks, a new signal processing architecture of a wireless relay has been proposed. And with an example of the heterogeneous wireless network consisted of GSM and CDMA systems, the detailed design is illustrated. The instance of the wireless relay demonstrates the feasibility of the proposed signal processing architecture.

Abstract: This paper based on the coordinated development mechanism of transportation and regional economy, and constructed and calculated the coupling coordinated model of transportation and economic development with the data of 31 provinces. The results are in the following: First, the construction of transport infrastructure is overall better, but the regional difference is quite big, the eastern region is better and mid-western regions are backwardness; Second, from the coordinated degree of transport and economic development, the eastern region is obviously advantage over the mid-western regions.

Abstract: Using GPS and GIS technology, the next generation of ERP (Electronic Road Pricing) system, are designed in this paper. The structure and approaches of the system has also been presented. The next generation of ERP system has resolved the issues of traditional ERP system, such as, high cost, unavailable for wide range of application. And, The new system not only more consistent with road pricing principles and objectives of reducing traffic congestion and air pollution, but also more flexible for the integration of ERP system with other Intelligent Transportation Systems (ITS). The paper also elaborated the key technical issues of the system.

Abstract: It exits nonlinear relationship between near infrared spectrum and print color. We could make use of diffuse spectrometric to get the near infrared spectra of print sample. The traditional method is using the partial least squares (PLS) to establish relation mathematical model, but the partial least squares (PLS) has the problem of low accuracy and bigger training sample size. The least squares support vector machine (LS-SVM) is presented in the paper to establish prediction model of print color. The result shows that the LS-SVM model has higher accuracy than PLS model.

Abstract: The remote sensing (RS) technology is a synthetic detecting technology and has been developed very quickly for recent years. As its main features, the RS technology could help to acquire data in multiple means, wide range, quick speed and high precision. Now it has been applied comprehensively in such area as geohazard prevention & mitigation, water conservancy engineering and transportation engineering. The application of RS technology in these areas was introduced in this paper. The future application was also prospected.

Abstract: Regarding ant routing algorithm parameters selection over mobile p2p networks, a basic ant routing algorithm is proposed and related parameters are analyzed. They are the power function of pheromone and evaporation time interval. They obey some parabolic functions of the velocity of nodes. A new method of ant routing parameters optimization based on an independent variable is proposed. Simulation results show that this algorithm selects the parameters effectively.

Abstract: The digital filter technology includes two aspects, which are the filter design process and filter realization. The article expounded the basic structure of FIR filter, with examples on the use Matlab to determine the FIR filter coefficient, analysis of the cycle of the buffer zone algorithm Principle, based on the algorithm, combination of filters designed to achieve the input of mixed-signal FIR digital filter. In the end, the filter is given before and after the input and output signal waveform simulation.
