Electronic journals: Their use by teachers/researchers of engineering and social sciences
Libraries must attend the needs of their different users. Academics are usually a particular kind of users with specific needs. Universities are environments where scientific communication is essential and where electronic format of journals is becoming more and more frequently used. This way it becomes increasingly important to understand how academics from different scientific areas use the available electronic resources. The aim of this study is to better understand the existing differences among the users of electronic journals in Engineering and Social Sciences. The research undertaken was mainly focused on the study of the use of electronic journals by teachers/researchers from the Faculties of Engineering and of Arts from the University of Porto, Portugal. In this study an international survey was used in order to characterize the levels of use and access of electronic journals by these communities. The ways of seeking and using scientific information, namely in terms frequency of access, the numbe...
Adopting computer technology for building virtual prototype model of special electromechanical device. After analysis and evaluation for structural form of that device, we find out the means and measures of optimization design. Take the advantage of that virtual prototype don’t limited by virtual experiment test length like physical prototype, there is no need for manufacturing and testing the physical prototype and we can acquire optimum design plan. To sum, we choose virtual prototype model in design electromechanical device can shorten the period of study and development electromechanical product effectively and improve design quality of electromechanical product conspicuously.
