基于径向基过程神经网络的油田开发指标预测

目前为止,现有的油田开发指标预测方法难以反映实际存在的时间累积效应对该指标预测的影响。因此,为提高油田开发指标预测的准确度,本文提出基于径向基过程神经元网络的油田开发动态指标预测模型,并将其应用到实际油田开发动态指标的预测中。实例分析结果表明,本文提出的径向基过程神经元网络的油田开发动态指标的预测方法精度高、速度快,是预测油田开发指标的一种较实用的方法。

An environment for End-User Development of Web mashups

End-User Development aims to find novel ways that are suitable and intuitive for end users to create their own applications. We present a graphical environment in which users create new mashups by directly selecting interaction elements, content and functionalities from existing Web applications without requiring the intervention of expert developers. Then, users just need to exploit a copy–paste metaphor to indicate how to compose the selected interactive content and functionalities in the new mashup. The environment is enabled by a Web-based platform accessible from any browser, and is suitable for users without particular programming skills. We describe the architecture of our platform and how it works, including its intelligent support, show example applications, and report the results of first user studies.

TSS （Tourism Support System） as a New Competitive Tourism Marketing Instrument

The recent trend in tourism marketing is focus on customer relationship management. Tourism industry today is one of the highest revenue generating industry and strategic approach for sustainable development of this industry hosts benefits not only for the tourism related stakeholders but also the community and economy on the whole. Oman is one of the most preferred destinations for the tourists especially after the declaration of Muscat, Arab tourism Capital for 2012. Thus to materialize this honor and position, the scientific study and analysis of tourist behavior will help to predict the future trend of tourism and will give direction for effort investment. This work presents a novel strategy to identify, analyze and highlights the main tourist behavioral factors that could increase tourists＇ loyalty to a specific destination or agency. The analytical TSS （tourism support system） will also classify customers into two categories--first category will be classified as ＂LT （loyal tourists）＂ and second category as ＂NLT （non-loyal tourists）＂. Dataset is collected from a tourism business organization. Twenty-four attributes and 545 instances were collected and were analyzed by algorithms like logistics, forest of random trees, naive Bayes, J48 and Id3. The explanatory variables were defined, and some transformations were done to identify the response variable. Entropy was used and adapted in order to find the response variable from the explanatory variables. The results obtained from this work confirm that the generated rules can be used for future prediction and tourism business can be improved and efforts can be directed in right place for the right consumer resulting in high return on investment.
