Public Private Partnerships (PPP) projects not only could attract abundant private capital to solve the scarcity of public funds, but also take advantage of techniques and experiences of private sector to accelerate metro development. PPP project capital structure had taken into account the interests of the Government, private investors and creditors, optimizing of the PPP project risks to an optimal capital structure to achieve a win-win situation. The object function was the weighted utility function of the internal rate of return and the debt service coverage ratio which included financial risk variables and financial assessment indicators to minimize the financial risk of the key participants and urban metro PPP projects. Then the Monte-Carlo simulation would draw an optimal capital structure, with the conclusion of the decision-making basis for investor, loaner as well as the governor.

Hazard assessment as a scientific tool provides technology support for emergency management. This paper summarizes systematically the wide-applied foreign hazard risk assessment models, and analyzes their advantages and disadvantages from the angle of methods, application characters. At the same time, this paper provides a set of hazard assessment model that suits the Chinese reality, summarizes the hazard assessment experiences in Sino-German project, details the steps of hazard assessment, creates the target system of hazard assessment, and researches typical cases according to the practice of hazard assessment. The result of research shows: this model suits the Chinese reality with instructive meaning and practical value and is worth of being extended all over China.

An optimized architecture is proposed for real-time automatic cloud detection system with Spectrum and Texture Analysis Combination (STAC) approach. The STAC approach is hard to be implemented in hardware, for the calculation of fractal dimension (FD) and angle second moments (ASM) of the approach consumes large computation time and hardware resources. By optimizing the calculation process of the FD and ASM, the proposed architecture efficiently improves the processing speed and dramatically reduces the logic resources and memories consumption compared to the automatic cloud detection architecture in standard STAC approach, with a 3 times running speed improvement and a more than 75% reduction of the hard resource consumption.

With the digital technology developments, Digital Cinema outperforms traditional films and attracts the movie industry. The first edition Digital Cinema System Specification was released by Digital Cinema Initiatives, LLC (DCI) in 2005, which advances the Digital Cinema development. We have developed a Digital Cinema Playback system compliant with the DCI Specification. It can extract and play the 2K-resolution component from the 2K/4K DCP (Digital Cinema Package) files at 24 fps, and support an up to 350Mbps video streaming service. Connected to Barco projector and Dolby digital device, this system can display the standard fully or partially encrypted test materials fluently and correctly. The synchronization of audio and video meets the DCI Specification.

The risks factor of construction projects are made an analysis on the characteristic of project, thus the international project risk evaluation system has been built based on the six risks that include bidding risk, market competition risk, engineering characteristics risk, contract risk, other participator risks and environmental risk. Construction of the project risk evaluation system has been established, and complementary judgment matrix is designed based on triangular fuzzy number. Furthermore triangular fuzzy matrix has been made a solution by expansion principle from the multi-attribute-based, priorities of complementary judgment matrices are provided. The result realize for identifying the pivotal risk factor of construction project risk.
