Abstract: Start is an important link of sludge anaerobic digestion process, it is can according to the sludge disposal in sludge volume and there is no vaccination to select the startup method. Gas components are the important study-factors of anaerobic digestive startup, to visually reflect the stability of the anaerobic digestion of the startup process, in order to accurately analyze the causes of imbalance of anaerobic digestion process, to guide the anaerobic digestion system startup.

Abstract: Cyber-physical systems (CPS) are complex distributed heterogeneous systems which integrating cyber and physical processes by computation, communication and control. During interaction between cyber and physical world, the traditional theories and applications has been difficult to satisfy real-time performance and efficient. Cyber-physical systems clearly have a role to play in developing a new theory of computer-mediated physical systems. The aim of this work is to analysis the features and relation technology of CPS that get better understanding for this new field. We summarized the research progresses from different perspectives such as modeling, classical tools and applications. Finally, the research challenges for CPS are in brief outlined.

Abstract: A kind of differential method is proposed for to eliminate noise disturbance and signal delay problems in ship heading control. First, an asymptotic observer is designed without ship motion dynamic parameters. Then, it proves that the observer is stable and the convergence conditions if given. At last, simulation result shows that the designed observer can suppress noise in ship heeding signals, and differential delay is improved.

Abstract: Selecting the promising technologies to incorporate in new products is challenging for enterprises, especially for those who compete in emerging high-technology industries. By integrating external factor evaluation (EFE) and internal factor evaluation (IFE) matrix, this study proposes a new technology selection method. The proposed framework is applied to a real technology selection problem faced by a bio-technology enterprise in the context of Chinas economic, political and social environment. Two major aspects and 24 external/internal factors are determined. This study uses analytic hierarchy process (AHP) method to sort the information and derives weights of each criterion. Empirical results indicate that the candidate technology is promising, and shall be developed as one of the enterprises primary products.

Abstract: Table tennis is a sport that combines collective force, skill, intelligence, will. The specialized of the practice methods is the premise to control the accuracy and validity for table tennis players. sports training project and the specificity of the content does not exclude the other training content and means conducive to the special athletic ability, but carefully analysis of the content and means to improve athletic ability, including direct effects and indirect effects long-term effects and short-term effects, in order to more effectively choose a variety of ways and means to improve services at special competitive level. nerve impulses generated by the alternating load training method to make the frequency of nerve payment impulses speed up and synchronization enhanced. Therefore, it can be used in table tennis athletes strength training alternating load training method, the better the quality of the power of the development of table tennis athletes.

Abstract: With the changes in a variety of environmental factors, supply chain management on competitive potential impact become more and more important, the development of supply chain management is to establish a theoretical basis, in addition to the theory of constraints and Heide symbol on the outside , inventory theory, the theory of purchasing, logistics theory has gradually become the theoretical basis. In addition, the mode of management of the supply chain management, management techniques was also discussed, as well as the differences between traditional supply management and contemporary supply chain management. At last we elaborate application of supply chain management theory at home and abroad.

Abstract: According to the guideline and target requirements of green ship engineering and the needs on the prevention and countermeasures of all kinds of natural disasters in ocean ships, a design scheme of the comprehensive information platform for the prevention of natural disasters based on ocean ships is proposed by the author in this paper. In this design scheme, the seamless time-space integration of heterogeneous information resources in different application systems is realized through using modern technologies such as computer technology, wireless communication technology, natural disasters forecast (alerting) technology, digital information integration processing technology, geographic information system (GIS), and global positioning system (GPS), and also higher-level information services are provided for the commanders (decision makers) of ocean ships in an integrated and unified way, thus promoting the self-security ability, distress searching and rescue aid decision-making ability, and the sea (especially ocean) transport and production operation abilities of ocean ships to be effectively increased. Besides, the re-optimization idea and improvement technology for the design scheme in the future allowable conditions, the unique information transmission technology (satellite communication technology) of the prevention of natural disasters in ocean ship, and the good development prospects of green ships are generally introduced and forecasted in this paper.

Abstract: The implementation of a project contains a lot of uncertainty, by their nature, random uncertainty, uncertainty and human factors (such as peoples limitations of understanding things and design methods, the use of analog approximate calculation results) due to the uncertainty of the future to better improve the structural reliability, this paper, the probability model reviewed structural reliability.

Abstract: The technical roadmap which has been produced since the 1980s is used in many fields. In reality it has formed many technical roadmaps standard. Summarizing and studying these standards has the important meaning to this emerging modern management tool's development consummation of the technical road map. This article has carried on the preliminary discussion from the technical roadmap content, the formulation procedure, the representation, the formulation method and so on.

Abstract: The aesthetic is a need, the humanistic psychologist Maslow made his famous "Theory of Demand. In his view, physiological, safety, respect, aesthetic, self-actualization level from junior to senior development needs. Form of beauty, art and design epitomizes the spirit of this advanced form of aesthetic needs. Pottery as a traditional media people becoming more concerned about environmental consciousness and spiritual level, but also both involved in the environmental space in the case of modern consciousness, showing it is a form of the emerging field of environmental art, pottery design consistent with human on the environmental aesthetic needs of the development of results, its aesthetic value cannot be ignored. An art form as a visual language, environment pottery body language has a unique aesthetic value and characteristics, and continue to join in today's visual culture under the influence of cultural concerns, its aesthetic characteristics in terms of interpretation of the visual language also has the image era semantic features. An area designed as a public environmental art, Environmental Ceramic aesthetic environment and the environment of people closely related to the artistic life, the concept of the art of living also make work pay more attention to the reality of the workplace awareness and survival, the manifestation of the spiritual needs Therefore aesthetic inject a greater angle. The visual aesthetic activity comes from the sensory response, but limited to the spiritual feeling, which mobilized human emotion, imagination, understanding mental function. These aesthetic mental activities are affected by different environment, different populations, different era with different cultural backgrounds and Cultural Complex of the impact and role.
