The corresponding computational program was developed using FORTRAN language. A comparison between the obtained solutions and the model test results was made to show the validity of the obtained solutions. The calculation results indicate that both the maximum lateral displacement and bending moment increase with the increase of the vertical and lateral loads and the pile length above ground, while decrease as the pile stiffness, the coefficient of subgrade reaction and the yielding displacement of soil increase. It is also shown that the pile head condition controls the pile responses and the vertical load may cause the instability problem to the pile. In general, the proposed method can be employed to calculate the pile responses independent of the magnitude of the pile deflection.展开更多

The weight of each evaluation index is determined with the methods of Delphi and expert consultation again.

This paper also attempts to explore the circumstances under which the original thematic progression pattern can be retained and the substitute should be reconstructed.展开更多

This proposal discusses the issues and dilemmas about the curriculum implementation in the EFL (English as a foreign language) education in China’s middle-schools and examines the nature of integrated contend-based (ICB) instruction by providing its rationale, definition, evolution, and delivery, and based on the above, it explores an excellent venue that the ICB could provide for Chinese student’s EFL learning and calls for the application of the curriculum of ICB into the EFL instruction in China’s secondary education.展开更多

While the students are learning, their learning is far from ideal or from what the lecturers had intended. Ramsden's findings suggest that there are different levels of learning and that the majority of students are not attaining the level that lecturer's judge to be of value. Learning the English language can be fun through the use of a Virtual Learning Environment (VLE). Obviously, the trend nowadays is the application of modern technology. Students can now get learning applications on their mobile phones, IPhones, IPads, and ITouch to widen their vocabulary and to increase their knowledge in the four skills such as, Reading, Writing, Listening, and Speaking. The accessibility of learning materials from the library can now be made available anywhere and anytime for students and teachers. This paper seeks to answer the following questions: (I) What is VLE? (2) What are the purposes of establishing VLE in a university? (3) How will the contents make student learning possible? (4) What will its impact on student learning be? The author believes that learning "how to learn" (metacognition) can be improved and enhanced for the students. The VLE serves as a supplementary learning tool in attaining such a goal.展开更多

Through a dozen years of English learning, some of them have high ability of passing examinations, but the practical application ability is barely satisfactory with relatively poor listening level and oral expression ability. The objective cause for this situation is the relatively single and stylization English teaching model used by traditional colleges and universities. This model only emphasizes learning on class which greatly harms students' English learning enthusiasm and initiatives. The result is that although the students passed CET4 and CET6 long time before their graduation, they still not dare to open their mouth to speaking concerning face to face English communications. Over the years, the researches on how to improve college students' English application ability never stop and they did obtain some achievements and show some opportunities, for example, if we can bring APP (application programs) into college English listening class, it will largely meet students requirements on English learning and this can also replenish and perfect traditional English teaching model.展开更多

The aim is to develop a form of technical assistance that supports them in the control of schedules, prevention of dangerous areas in the work place, warnings and automatic alarm generation. The device chosen to exchange all this information is a smartphone based on Android Operating System and GPS (Global Positioning System) technology mainly. A set of Android applications has been developed using Java language, and controlling the device via Google-developed Java libraries. All of them are connected to the Server Application through the Communications Module. The Server Application Module provides the assistants or psychologists the possibility of supervise all the handicapped people activities. The assistants, psychologists and users have all evaluated the application very positively as it covers disabled people's needs perfectly.展开更多
