A structure model of urban traffic system evolution is built based on the analysis of the factors influencing the system evolution and the hierarchy between the factors. Then the influencing degrees of the factors are quantificationally analyzed by DEMATE （decision making trial and evaluation laboratory）. The analysis results indicate that the traffic mode structure which achieves the highest central degree is the dominant influencing factor of the urban traffic system evolution, and that economy development and the traffic policy are the second important factors that also affect the Waffle mode structures. Furthermore, physical geography is a basic restriction to the urban traffic system evolution.

In order to compensate reactive power and eliminate the negative-sequence and harmonic currents of electrified railway system, a new railway power compensator （RPQC） is proposed. The RPQC consists of three single-phase voltage source converters based on the chain circuit inverters. It connects the railway traction power system directly without isolation transformer. Power rating of the conditioner can be increased simply by adding chain links in series. The proposed topology is suitable for traction power system with impedance-matching balance transformer. Regarding the traction substation as a control object, the power quality of the traction substation with RPQC can be improved integrally. The RPQC always makes the traction substation become a nearly balanced three-phase power system in the public grid whether the loads of two feeders are balanced or not. According to simulation results, the proposed RPQC is feasible, and it can compensate reactive power, harmonic, and negative-sequence currents in two feeders together.

The Controller Area Network (CAN) is a well established control network for automotive and automation control applications. Time-Triggered Controller Area Network (TTCAN) is a recent development which introduces a session layer,for message scheduling,to the existing CAN standard,which is a two layer standard comprising of a physical layer and a data link layer. TTCAN facilitates network communication in a time-triggered fashion,by introducing a Time Division Multiple Access style communication scheme. This allows deterministic network behavior,where maximum message latency times can be quantified and guaranteed. In order to solve the problem of determinate time latency and synchronization among several districted units in one auto panel CAN systems,this paper proposed a prototype design implementation for a shared-clock scheduler based on PIC18F458 MCU. This leads to improved CAN system performance and avoid the latency jitters and guarantee a deterministic communication pattern on the bus. The real runtime performance is satisfied.

It is a very difficult and pressing issue to how to analyze the reliability of feature-parameters of complex radar emitter signals. In this paper, the ultimate state model of the signal feature-parameters is proposed based on the structure ultimate state of structure reliability theory, and the reliability models of signal feature-parameters are presented by point-estimate theory based on the structure reliability model. The reliability of the common feature-parameter PW and TOA are analyzed. The theoretical analysis and experimental results show that the reliability of feature parameters can be obtained by using the proposed approach when the variable distributions of the feature ultimate state function and bounds of features are known. Moreover, with the SNR and the bound of features increasing, the reliability of features are rising.

科学方法论对科学活动的研究,目的在于探索科学发现和科学检验所遵循的基本规则,并为科学预测和科学决策提供合理的依据。我国关于科学方法论的研究,主要集中在科学发现和科学检验这两个阶段,而对科学方法论的应用阶段———科学预测和科学决策———的研究则较为薄弱。本文通过波普尔证伪主义方法论与决策科学的比较,认为无论在决策科学的基础理论方面还是在决策科学的方法上,证伪主义方法论对决策科学都产生了重要的影响。

Since the theory of generalized two-dimensional (2-D) correlation spectroscopy was proposed, it has been keenly concerned in scientific research and its analytical method has been widely applied in various analytical fields. The mathematical process to construct generalized 2-D correlation spectroscopy and the physical meaning of 2-D correlation spectral map are described, and three examples in the fields of chemical analysis and molecular biology are provided, such as the component analysis of organic solvent, the analysis of biological molecules in the solvent with different pH values and structural analysis of protein. The theory and analytical method of generalized 2-D correlation spectroscopy are also detailedly commented.
