In this paper, ULearn (University of Surrey learning on-line) and e-learning techniques are used to enhance the students’ understanding and participation in Dynamics modules for an undergraduate programme in the School of Engineering, University of Surrey. The Dynamics modules are taught at Levels 2 and 3 and contain several mechanisms and vibrating systems. The modules consist of several chapters, each of which has its own folder, or content file, in ULearn. In addition to the discussion board and chat room, on-line simulations have been made available and integrated within ULearn. In order to evaluate students’ understanding and encourage the student participation in ULearn, timed on-line assessments, in the form of multiple-choice quizzes, have been designed. The feedback of the students has indicated that the use of ULearn was of great help to improve their understanding of the Dynamics modules. 相似文献

It is still unknown how the MDGs have impacted the socioeconomic situations of the elderly in Nigeria. This has become essential to appraise the attainability of the MDGs in Nigeria. Quantitative data were collected through an individual-based questionnaire. Multistage sampling was employed to select local government areas, enumeration areas, and individuals for the study. In all, 810 respondents were interviewed. The study shows that more than 3 out of every 10 female respondents mentioned trading; more than a quarter of their male counterparts mentioned the same. Only 3.5% of the female respondents and 7.5% of their male respondents mentioned investment as their sources of income. A few of the respondents live above a dollar daily. The general response among the respondents is that the impact of MDGs is yet to felt. The paper asserts that primitive capital accumulation via corruption causes poverty for some, increased social inequality, and geographical objectives, which are currently insufficiently alleviated by policy action. 相似文献

An experimental machine vision apparatus was used to identify and extract recyclable plastic bottles out of a conveyor belt. Color images were taken with a commercially available Webcam, and the recognition was performed by our homemade software, based on the shape and dimensions of object images. The software was able to manage multiple bottles in a single image and was additionally extended to cases involving touching bottles. The identification was fulfilled by comparing the set of measured features with an existing database and meanwhile integrating various recognition techniques such as minimum distance in the feature space, self-organized maps, and neural networks. The recognition system was tested on a set of 50 different bottles and provided so far an accuracy of about 97% on bottle identification. The extraction of the bottles was performed by means of a pneumatic arm, which was activated according to the plastic type; polyethylene-terephthalate （PET） bottles were left on the conveyor belt, while non-PET bottles were extracted. The software was designed to provide the best compromise between reliability and speed for real-time applications in view of the commercialization of the system at existing recycling plants. 相似文献

A functional monochromator model in a cardboard box, made from rotatable grating using a digital versatile disk is described
to highlight the working principles of a UV-Vis monochromator. The light source is a bright white LED and the colored bands
from the exit are displayed on the screen. The concept of absorption, complementary color, excitation and fluorescence, flame
emission spectrum, and wavelength dependence of light scattering can be visually shown in this model. With a minor modification,
one can use the same box to monitor flame emission spectrum of sodium and different light sources. As an optional activity,
the same properties are observed on a scanning spectrophotometer. 相似文献

The democratization of education has brought forth an unprecedented demand for education by the masses, especially at the tertiary level. However, the availability of education is hampered by limited resources to provide pervasive and effective teacher–student interaction, changing lifestyle patterns, changing expectations of the students, and the problems associated with the great urban–rural divide and nonuniform access. The problem of availability of education is compounded by the tide of globalization and the Internet that demands not only high efficiency but also competitive delivery of services and goods in all sectors of our economy, including education. Education is not immune to these current trends. It is imperative that education institutions rise up to the challenge in meeting the demand of a more discerning, discriminating, mobile, and selective student population. It is imperative that education institutions reconsider the necessary ingredients to make learning effective, relevant, and fun for the students. Our company, Kolej Damansara Utama (KDU), has embarked on an education experiment begun almost 3 years ago to implement a student-centered, teacher-facilitated, Information and Communications Technology (ICT)-enabled and knowledge-based initiative. The goal of this experiment has been to create an active learning environment, and to promote learning for our students. The knowledge ecosystem, comprising students, teachers, administrators, parents, partner institutions, employers, and the community at large, forms the KDU e-Community Network (KCN). The KCN enables passive, interactive, collaborative, and constructive learning to take place as long as the stakeholder has a connection to the Internet. 相似文献

Objective
Scandix pecten-veneris L. is a less studied wild edible herb and is considered an extinct plant species in many parts of the world. This study was designed to evaluate its phytochemical composition and biological potential of S. pecten-veneris L.Methods
Phytochemicals including alkaloids, flavonoids, polyphenols, and tannins were determined in extracts of S. pecten-veneris. Antioxidant activity was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH), while reducing power was tested by ferric reducing/antioxidant power (FRAP) assay. Antimicrobial activity against seven bacterial and four fungal strains was evaluated using agar well diffusion assay. Enzymes inhibition study was performed for urease, phosphodiesterase-I, and catalase-II.Results
S. pecten-veneris showed moderate antiradical activity and reducing potential of hydroxyl radicals to about 20% of the initial value. The antioxidant activity of various extracts of S. pecten-veneris showed a linear correlation with total phenolic contents in the order of water>n-butanol>chloroform>ethyl acetate>methanol extracts. S. pecten-veneris leaves showed the highest inhibitory activity against Staphylococcus aureus while the highest antifungal activity was observed against Candida albicans. The plant extract was most potent against urease enzymes but showed moderate activity against phosphodiestrase-I and carbonic anhydrase-II.Conclusions
Our data demonstrate that in addition to its culinary uses, S. pecten-veneris has good medicinal potential and hence could be used for treating some specific health ailments.7.
