Both of them have limitations, however. We presented an integrated model of these two methods to increase the efficiency and quality of the problem solving process for conceptual design. AD is used for systematically defining and structuring a problem into a hierarchy. Sometimes, the design matrix is coupled in AD which indicates the functional requirements are coupled. TRIZ separation principles can be used to separate non-independent design parameters, which provide innovative solutions at each hierarchical level. We applied the integrated model to the heating and drying equipment of bitumen reproduction device. The result verifies that the integrated model can work very well in conceptual design.展开更多

Compact City is an urban planning and development concept which promotes relatively high population density associated with an integrated and mixed-use land district. It is enabled by transit-oriented development and results in low transport-related energy consumption and reduced the GHG (Greenhouse Gases) pollution. Compact City conserves the natural capital of land mass and subscribes to the strong sustainability ethics. ICT (Information and Communications Technology) could be deployed to optimize the Compact City operations by first tackling some of the development problems associated with Compact City and also unleashing new urban innovations and functionalities to achieve sustainable urbanization. The paper suggests and elucidates several general systemic synergies archetypes such as co-benefits, cascading, ICT infrastructure reuse, etc., which could be leveraged to facilitate the emergence of compact green smart and resilient city. These archetypes are solutions to the Compact City paradigm thus conductive to the development ofa Sustainability Science of Compact City.展开更多

People carry different schemas (background knowledge) that play an important role in guiding people's behaviors in intercultural communication. The purpose of this paper is to attempt to theoretically apply communication strategies to the development of intercultural communicative competence in light of Cultural Schema Theory. It focuses on the relationship between cultural schema and intercultural communicative competence. Some pedagogical implications are given that cultural schema could be previously intended to help communicaters have a better and easier life when they are living in other countries, such as awareness raising, knowledge acquisition, emotional management, and skills development. This paper is written on the basis of a collection of the Chinese university students' experience of culture-learning. The study has certain significance in the practice on cultural acquisition, communication competence, and intercultural communication.展开更多

A description of the chaotic approach for the DNDP model is described in details. Then a numerical example for the DNDP is carried out to investigate the chaotic approach. The results have been encouraging, indicating that the chaotic approach has great potential ability in finding the optimal solution of DNDP models.展开更多
