Abstract: In the use of Ajax technology on web pages, it is needed to execute client-side Javascript code to present dynamic information. This will result in that a lot of useful data cannot be retrieved with search engine. This paper will introduce a method based on calling browser API and, add the preprocessing stage and put forward effective element specification before trigger the Ajax page events. Besides, several experiments are introduced to testify it’s feasibility and effectiveness.

Abstract: The large-scale competition, which usually refers to a major international sports events and domestic levels, provincial and municipal as well as state-level large-scale games, such a massive game, exists the characteristics of large-scale, big investment, big risk and a longer cycle, etc. According to above uncertainty factors, natural risks, there are main risks, like social risks and personal risks. So, it is indispensable to bring information management technology into the big game, which makes the large-scale competition more rational scientific, reduces the risk, and makes large-scale competition successful.

Abstract: Because studies of traditional regional creations neglected the main role and value of human, ignored daily goods for the service of ordinary people and the relevance with the nonmaterial culture resources such as folk literature, folk rituals, folk beliefs, regional design has turned into the imitating, patching and borrowing from traditional forms, styles and prototypes, and ultimately become an over-elaborated decorative display, and gone further and further away from the essence of life. Therefore, reconstruction of both the implicit and explicit knowledge systems of the regional cultural resources becomes necessary for the purpose of finding out the deep value of regional cultural creations. We should explore deep into the relationship system involving people, matter, place, time and meaning through events of culture and life to activate the value and meaning value of traditional regional creations in contemporary life and in accordance with the sense of belonging in cultures.

Abstract: Lying to the north of the Haixinsha Island, where the Opening and Closing Ceremonies of 2010 Asian Games were hosted, the Flower City Square (the Square) by itself forms an integral part of the new Central Axis of Guangzhou. Thanks to the media publicity of the Asian Games, the Square has now become a household name in Guangzhou and China. Relating major sports events with city squares, as in this case, taking advantage of the Asian Games to foster a festival atmosphere on the Square and present a spectacular metropolitan view, is proven to be a very effective measure to brush up the city image. This paper, based on a two-year survey on the Square, the record of spatial annotation analysis on uses of the Square, and questionnaire surveys involving the randomly selected visitors on the Square, compares the uses of the Square during and 2 years after the 2010 Asian Games through the means of Frequency Analysis, probes into the visitors satisfaction degree on the Square and its evaluation factors with the Factor Analysis Method, and demonstrates the impact of mega-events on the city squares and its implications.

Abstract: In this paper, we propose a framework of smart supermarket using Internet of Things, which includes three layers: perception layer, data management layer and application layer. This framework is quite powerful, flexible and extensible for constructing smart supermarkets. The key technological issues for this framework are also discussed.

Abstract: The purpose of this study is to find out the AE characteristics and fracture mechanisms through AE signal analysis for the weldment, PWHT specimen and basemetal of the pressure vessel steel. Charpy sized specimens were taken from the multi-passed weld block. Specimens were given to four point bend and AE tests. Lots of AE signals were emitted from the weldment compared with the basemetal and PWHT specimen. Besides, amplitude for the weldment was the largest, followed by PWHT specimen and basemetal and more AE counts for the weldment were emitted in the process of deformation. Lots of microcracks around the notch for the weldment were formed so that more AE signals were produced. In addition, second phase particle such as MgO for the basemetal acts as AE source. However, in case of weldment, debonding mechanisms between matrix and hard oxides which are formed during welding in air attributed to the emission of AE signals and softened particles for the PWHT specimen cause to produce the low level AE signals.

Abstract: The purpose of this study is to find out the method to detect AE signals at around the notch tip and to evaluate the AE signal characteristics for the basemetal, PWHT(post weld heat treatment) and weldment specimens of SA-516 steel during bend test. AE signals were produced in the process of plastic deformation. AE signal strength and amplitude of the weldment was the strongest, followed by PWHT specimen and basemetal. More AE signals were produced from the weldment because of the oxides, and discontinuous mechanical properties. The stronger AE signal strength, amplitude and more AE event counts for the weldment were shown.
