A transparent and ubiquitous access framework for networking and embedded system laboratories

Abstract

With the advances in network technology and development of an e-learning population, using the Internet to realize a distance laboratory has become prevalent and the distance laboratory can be accessed anytime from anywhere. However, it is difficult to present a seamless environment from the traditional physical laboratory into a distance laboratory. Practical devices in the traditional laboratory rarely supported distance access functions, and thus, constructing distance laboratories is difficult and time consuming. Hence, this work presents a distance laboratory framework with transparent and ubiquitous access platforms for various console-based experiments, especially for networking and embedded system laboratories. The proposed system can support multiple users to access a device at the same time. Thus, students can easily share their experiences with each other to increase cooperative learning chances. Moreover, the proposed framework can be integrated to various distance laboratories and the user can access multiple platforms in one or several distance laboratories at the same time. The experimental results demonstrate that the proposed framework can effectively improve the learning effect and the access platform can be used to increase the utilization of system resources. It can also reduce the cost of conducting laboratories and enhance student learning interest. ß

The Effects of Mobile-Computer-Supported Collaborative Learning: Meta-Analysis and Critical Synthesis

“…Applying the above-described screening criteria resulted in the exclusion of 15 studies in which mCSCL was implemented in both the experimental and control groups (e.g., K. Lai & White, 2014 ; T. J. Lin, Duh, Li, Wang, & Tsai, 2013 ). In addition, 19 articles that did not have sufficient information for ES calculations were excluded, such as those that did not report the number of people in each group, those that did not report the results for statistical inferences, or those whose statistical inference results were not sufficient to calculate ESs (e.g., Baloian & Zurita, 2012 ; Li, Dow, Lin, & Lin, 2012 ). After the third stage of screening, there were 48 articles left—47 journal articles and 1 doctoral dissertation—all of which were published between 2000 and 2015.…”

Embedded and real-time systems classes in traditional and distance education format

“…Remote laboratories offer a more realistic laboratory experience; however, this approach often requires expensive equipment and networking resources [6]. Therefore, a common way to address this issue has been to have distance education students combine simulations with using a low-cost, stand-along kit to construct and test their design at their home site [4] [16].…”

Dynamic spectrum extraction method based on independent component analysis combined dual-tree complex wavelet transform

“…It has achieved a series of results on spectrum extraction, signal acquisition and clinical trials, etc. 17 DS demands spectral data of high quality, thus it requires the measurement accuracy of spectral data to be as high as possible. Frequency domain analysis 18 and single trial estimation 19 are two famous extraction methods for DS currently.…”
