In this paper, a Moodle-based educational system has been constructed by providing friendly interface to fit most students in e-learning. For the website implementation, the authors take the course "Multimedia Implementation Using JAVA" as a case study. From the modified Moodle-based educational system, the browsing time of each web page for students can be obtained. By analyzing the recorded information, teachers can find out factors which will affect students ' learning performance, so as to apply the proposed learning performance evaluation mechanism to evaluate students' learning performance for providing adequate auxiliary learning materials to individual students.

To reduce energy demand (both fossil fuel and renewable energy) for cooling the urban heat island environment, some solutions have been studied. Among these methods, the water spray system is considered more flexible due to its dynamic controls. This study investigated the cooling effect of water spray systems in the street canyon under different aspect ratios and high relative humidity environments using a computational fluid dynamics model. This model was validated with water channel and wind tunnel experiments. The results showed that the most effective cooling area was the area just under the spray nozzles. However, in a narrow street canyon, people in the middle of the street may feel the cooling effect because of the dispersion and accumulation of the cooled air. Our simulations demonstrated that air under the nozzles was saturated and this revealed that under drier conditions the water spray systems will have higher cooling performance. We also found that using large water droplets created a wider cooling area in the middle of the street canyon, and this phenomenon was not changed much if the nozzle height was increased from 2.5 m to 3.5 m.

In recent years, Web-based learning has become one of the major applications of the Internet. For Web-based learning, it is important to design an intelligent curriculum Website for students and to make teachers understand the learning situation of each student in order to provide adequate auxiliary learning materials to individual students. Seven factors, including learning behaviors, were assumed to affect the learning performance of students. These assumptions have been analyzed to determine their effectiveness, and five factors, the degree of interest in the course, the degree of the familiarity with the computer, the number of Web pages browsed, the length of the course content, and the degree of difficulty of the course content are selected for evaluating the learning performance of students. In the research, a Moodle-based curriculum Website was established as the experimental platform to record students’ learning behaviors for analysis. By applying the extenics engineering method, a learning performance evaluation scheme is proposed to generate an evaluated learning performance of individual students for instructors’ reference. Thus, according to the evaluated learning performance, instructors can provide students with more adequate learning materials in accordance with individual students’ learning performance.
