After providing a background of the local land transportation scene, the paper provides a chronological discussion of the metro development in Singapore where the characteristics of each new metro line was briefly discussed. The next part of the paper shares some features and initiatives through developing the Singapore metro system over the years, such as funding arrangement, bringing artworks to transit stations, integrated planning between road and rail, integration between transit facilities with non-transit developments, barrier-free accessibility and improving connectivity to the metro stations, and transforming transport nodes into lifestyle hubs. Finally, the paper concludes by discussing the challenges on the land transport system in Singapore and the way forward.展开更多

However, more attention should be paid to the teaching quality to develop this web based College English teaching model. Therefore, the construction of the quality guarantee system is of major significance to promote the effective design of web based College English course system and improve the quality of web based College English teaching.展开更多

The mass appraisal system has been developed in some foreign countries, especially in American for a long time. In Taiwan, we still have few experiences in using computer-assisted mass appraisal system, especially using artificial neural network （ANN）. This article has two objectives： （1） to illustrate application of ANN to the Kaohsiung property market by the method of back-propagation. The study is based on the properties data of sales price, we also use multiple regressions in the same data; （2） to evaluate the performance of two models by using the mean absolute percentage error （MAPE） and hit ratio （HR）. This paper finds that using artificial neural network （ANN） is able to overcome multiple regressions＇ methodological problems and also get better performance than multiple regression model （MRA）. These results are useful in helping local government to assess their assessment value.展开更多

We employ Secrecy Capacity （SC） to charac terize the security of transmission. In order to ac curately describe the timevarying characteristic, related channels are modeled as FiniteState M ark ov Channels （FSMCs）. The remaining energy of candidate node is considered in a similar way.展开更多
