Abstract: The cement stabilized macadam mixed with different admixture influence the vibration compaction effect , under certain aggregate gradation and vibration parameters, carry out vibratory compaction and compaction tests on cement stabilized macadam with incorporation of different admixture and cement dose of 4% , test results show that: when single mix water-reducing agent, adding 1.0% , cement stabilized macadam most easily compacted; when single mix fly ash, the mixing 30%, cement stabilized macadam most easily compacted; when compound mixed with fly ash and water-reducing agent, help reduce optimum water content, increasing the maximum dry density compared with single mix water-reducing agent or fly ash , and water-reducing agent dosage is 1.0%, fly ash dosage is 20% are the best.

Abstract: Spectral prediction of spot color ink has always been a difficult problem in the field of color research. The current paper adopted color parallel and superposition models to deal with the Clapper-Yule model and to simplify the prediction model of spectral reflectance of spot color ink. respectively. Based on the experimental verification. the simplified method has a certain practical application value. and the spot color prediction of general presswork can meet the requirements fully. The most important consideration is that the simplification can largely reduce the computational difficulty. Moreover. the current paper compared the accuracy of color parallel model with the superposition model to simplify the spectral prediction model of spot color ink. The result showed that the color superposition model has higher accuracy in simplifying the spectral prediction model of spot color ink.

Abstract: Considering information asymmetry between the entrepreneur and external investors, this paper makes a hypothesis that the entrepreneur would manipulate information when issuing shares, and derives a stock issue price model based on information manipulation and effort the entrepreneur would make. Analysis of the model shows the level of information manipulation does affect the stock issue price. Market regulators should improve the capacity of identifying information manipulation and increase penalties for manipulators, so that the market can be more accurately pricing shares being issued.

Abstract: Because of its unique role in the information flow analysis, the design structure matrix (DSM) is widely used to the optimization of the organization, parameter and other aspects. Its matrix representation, the dynamic features make it possible that be applied to optimization of business processes, but so far the DSM in the business process application is also rare. In the paper, DSM is tentatively applied to topological sort in the business process and is compared to the traditional topological method. These explorations for the application of the DSM in the optimization of business processes are positive.

Abstract: Manufacturing industry is pillar one of China industry, and is also major upstream of resource wasting and environmental pollution. This paper approached to sustainable development of manufacturing industry, one Machine Tool Plant was used as an example to analysis how to lead towards sustainability applying sustainable development theory of The Natural Step. This paper combined theory with practice, the result showed the model of theory has good theoretical and practical value, and could be a new path of exploration for sustainable development of manufacturing industry

Abstract: In response to the increasingly stringent diesel emission regulations, the paper analyzes the relationship of the low-speed marine diesel engine's emission with the combustion process, the fuel injection law, the exhaust recirculation and the SCR. Then the scheme of the fuel injection system with the high-pressure common rail for the low-speed diesel engine is proposed, and the test system for the diesel engine's emission performance is established. Through the experimental research, the optimization and matching technology for the diesel combustion process based on the emission control is analyzed, and the best injection law of the diesel engine is revealed under the different conditions. That will provide the technical support for the design and operating management of the diesel engine.

Abstract: In this work, the notion of orthogonal two-directional shortly supported wavelets with poly-scale is developed. A new method for designing two-directional orthogonal wavelet wraps is proposed and their properties is investigated by means of time-frequency analysis methodand, operator theory. The existence of shortly supported orthogonal two-directional vector-valued wavelets associated with a pair of orthogonal compactly supported vector-valued scaling functions is investigated. A new method for designing a sort of orthogonal shortly supported two-directional vector-valued wavelet functions is presented by using multiresolution analysis and matrix theory.

Abstract: Sulfonated chitosan (SCS) was prepared from chitosan and sulfuric acid via sulfation reaction. SCS was used as superplasticizer in cement. The test showed that the maximum fluidity of the cement paste was 232 mm with dosage of 0.75 wt % at water to cement ratio (w/c) of 0.29. Meanwhile, lesser loss of fluidity and slump over 60 mins were observed comparing to naphthalene sulfonated formaldehyde condensates (NSF). A well-distribution of cement particles can be seen from the image of SEM in the sample of mortar prepared by SCS. The water reduce ratio of SCS reach 19.2 %. The applied results showed that SCS could slightly improve the mechanical properties of mortar. The paste fluidity, mechanical properties and slump loss of the cement paste incorporated SCS indicated that it can be used as superplasticizer in concrete.

Abstract: Fiber grating is an optical passive device which is developed very fast in recent years. FBG is the most grating which is used as fiber sensor. Cross-sensitivity of fiber grating sensor is an important problem which is restricted the development of the fiber sensor. We do a deep research on the cross-sensitivity problem of the Fiber Bragg grating in this paper. Based on the basic principle of how the cross-sensitivity problem is produced, we suggest a modification in a dual-wavelength matrix calculation method which is used to solve the cross-sensitivity problem in traditional. The modified dual-wavelength matrix calculation method has a higher accuracy than the traditional method.
