Abstract: The Mechanical and Technological Innovation Centre (CDMIT) of the National Autonomous University of Mexico has a research area focused on the design of upper limb prosthesis. A large number of prosthesis have been developed and tested. This paper presents the analysis made to different proposals of myoelectric hands based on TRIZ. Two TRIZ tools were applied: The Innovation Situation Questionnaire (ISQ) and the Radar of Evolution. The analysis was made in terms of time, space and the user interface. The ISQ helps to better define the scope of the problem through six basic questions; each question provides a different view of the problem. The radar of evolution helps to make a selection of trends of evolution depending on the product or system, as an analogy of a benchmark. The analysis was made considering the state-of-the-art hand prosthesis: i-limb, be-bionic, Michelangelo and Myohand against the prosthesis prototypes developed by the CDMIT. The result of this tool is a diagram that reveals the level and opportunities of evolution. These opportunities imply a strengthening of research areas not only in the CDMIT but around the world. The conclusion achieved is that different design paradigms linked to bio-mimics criteria are needed to design more innovative user-friendly prosthesis.

Abstract: the online social network has served as a critical medium for information dissemination, diffusion of epidemics and spread of behavior. In this paper, we proposed a model of opinion spreading and evolution based on online social network, where the social temperature is taken into account. First, the forms and features of the opinion spreading and evolution in social network are analyzed. Then a model of opinion spreading and evolution is established, in which social temperature as an external factor participate the opinion evolution of nodes and then affect the opinion spreading. Simulation results show that social temperature has an important impact on the opinion spreading and evolution.

Abstract: The Luyang Lake, a declined ancient lake, is located in Lubotan area in northeast of Shaanxi Guanzhong Plain. As one of the relict lakes of Sanmen Lake in early Pleistocene, Luyang Lake formed in the Pleistocene of Quaternary period dating back to about 3 million years ago, and later gradually retreat into a beach in the late Ming dynasty due to crustal tectonics and global climate change. Water area of the lakes becomes larger due to development of irrigation systems and artificial water source in the past 30 years. And now, the groundwater level is rising and Wetland trend intensifying.

Abstract: Riverbed structures were developed in many very coarse gravel-bed rivers as a result of fluvial morphology. And the distribution of them was obviously relevant with environment conditions. This paper carried out field investigations in natural rivers, to study the riverbed structures size, distribution in the basin, as well as their connections with local environmental conditions. The results indicated that: The structures can enhance resistance to water erosion and protect riverbed. Given the conditions of little bedload, the structure intensity is in direct ratio to the unit-width stream power which consumed by the structures when rivers are in dynamic equilibrium. If the structures are not able to dissipate the whole power, the river status turns to disequilibrium and the riverbed will be eroded by excess energy. The fluvial morphology of coarse-grained riverbed is controlled by this process.

Abstract: The evolution of adaptive IT capability in the ever-changing business environment are not well explained. To fill this gap, this paper depicts a micro-interpretation of the evolution of adaptive IT capabilities from a routines perspective, and uses the agent-based simulation methodology to simulate the evolutionary process of adaptive IT capability as well as to identify the underlying principles.

Abstract: The study explored global climate change influence on water resources in Yellow River basin. A HBV hydrological model was developed to simulate the rainfall-runoff relationship at the region. Importing the CCLM climate model data, runoff at Lijin station was obtained in 2000-2039. The results indicate: (1) the annual average runoff depth is 1213mm, runoff in summer is larger than in spring,autumn and winter. The water resources decrease in three months (March, April and Jun) and increase in other months. (2) for inter-annual variations, the water resources increases slightly, and increase trend is about 64.8mm/10a. Water resources are insufficient in 200-2016, and rise gradually from 2017. (3) for different decades, the water resources are lack relatively in 2001-2010 and 2011-2020, and the differences are-59.4mm and-76.0mm respectively. While, the water resources in 2021-2030 and 2031-2039 are abundant, and the differences are 90.6mm and 88.8mm respectively.

Abstract: San ye House Village are located in Farming-pastoral zone of eastern Inner Mongolia after a hundred years of development history, from mainly nomadic settlements into agricultural and pastoral settlements. The evolution of the settlements' pattern experienced a total of three stages. With the combination of different periods of settlement pattern analysis, the characteristics of San ye House village settlement pattern development is studied and the reasons for its formation and evolution process are presented.

Abstract: The reasonable layout of city space is an important guarantee for the healthy development of cities. Along with the expansion of urbanization, economic structure transformation, urban space layout is also in constant change. Urban spatial development of society, economy, the humanities, the ecological factors, especially the industrial structure adjustment to the urban development played an important role. Based on the theory of using Baotou city as an example, analyzed the evolution of urban spatial form of Baotou and puts forward the countermeasures.

Abstract: In order to promote the educational informationization, most universities, which own different cycles with various understanding, are experiencing the transition from campus network construction to digital campus construction. Similar difficulties and solutions are encountered in the course. This text is dealing with the process of educational informationization in Chongqing Normal University, offering a good example for your reference.

Abstract: When Internet has been becoming a platform of all kinds of resources sharing and integrating, service computing can just satisfy this kind of computation. When the users needs and the running environment change frequently, the original structure of the composite service should be rebuilt and reconfigured to need these alterations. Since the availability and the reliability of service composition will not be guaranteed, the correctness of service composition evolution must be verified. In this paper, a formal model-WSPN was presented to describe service composition evolution, WSPN can express the structure of service composition and also can simulate the evolving process of the composite service. In order to keep the evolving correctness of Web service composition, an algorithm was provided to verify the composition relationship between both component services, in this way, the reasonable relationship can be obtained. Finally, the concluding remarks and the future work were pointed out.
