Monitoring and measuring the maximum power of solar modules in real time is essential for evaluating the performance of a solar electric system. In order to monitor the rapidly fluctuating output power of high-concentration photovoltaic (HCPV) modules, a simplified maximum power point (MPP) estimation and measuring system is presented in this paper. The fractional open-circuit voltage (FOCV) technique and a controllable electronic load circuit were proposed to estimate and measure the MPP. The feasibility of using the FOCV technique on HCPV modules was evaluated, the results of which demonstrate the maximum voltage and power estimation accuracy of the experimental modules. The main advantages of this simplified HCPV MPP measurement system are rapid response time, low complexity, and ease of implementation. © 2014 IEEE. Source

This paper presents a wideband mixer chip covering the frequency range from 3.4 to 6.8 GHz using TSMC 0.18 μm CMOS technology. The linearity can be improved using multiple-gated-transistors (MGTR) topology. The measured 3-dB RF frequency bandwidth is from 3.1 to 6.8 GHz with an IF of 10 MHz. The measured results of the proposed mixer achieve 7.2-4.3 dB power conversion gain and 2-3 dBm input third-order intercept point (IIP3), and the total dc power consumption of this mixer including output buffers is 2.9 mW from a 1 V supply voltage. The current output buffer is about 2.17 mW, and the excellent LO-RF isolation achieved up to 54 dB at 5 GHz. The paper presents a mixer topology that is very suitable for low-power in ultra-wideband system applications. © 2010 Elsevier Ltd. All rights reserved. Source

The ever-increasing demand for H.264 scalable video coding (H.264/SVC) distribution motivates researchers to devise ways to enhance the quality of video delivered on the Internet. Furthermore, researchers and practitioners in general depend on computer simulators to analyze or evaluate their designed network architecture or proposed protocols. Therefore, a complete toolset, which is called myEvalSVC, for evaluating the delivered quality of H.264/SVC transmissions in a simulated environment is proposed to help the network and video coding research communities. The toolset is based on the H.264 Scalable Video coding streaming Evaluation Framework (SVEF) and extended to connect to the NS2 simulator. With this combination, people who work on video coding can simulate the effects of a more realistic network on video sequences resulting from their coding schemes, while people who work on network technology can evaluate the impact of real video streams on the proposed network architecture or protocols. To demonstrate the usefulness of the proposed new toolset, examples of H.264/SVC transmissions over 802.11 and 802.11e are provided. © 2012 KSII. Source

To strengthen the information technology skills of students living in remote areas, the Ministry of Education of Taiwan advocated the 2008 Country Development Plan to diminish the gap between urban and rural education development. This study proposes a hypothetical model to evaluate the effectiveness of the government policy in decreasing the Rural-Urban Knowledge Divide in higher education. There were 427 participants in this study. From the research results, we found that the government policy had a significant impact on reducing the Rural-Urban Knowledge Divide in higher education, and it demonstrated that most hypotheses were supported. Finally, as a virtual teacher or classroom for students living in rural areas, this research provides several suggestions as strategies in building up prospective resources for a Digital Opportunity Center or e-learning environment beneficial for both rural and urban students.© 2013 Elsevier Ltd.

The military landscape of Kinmen is an historical treasure left behind following the threat of war. Kinmen used to be a key military location of high strategic value, and witnessed some decisive victories battles. However, owing to rapid developments in the worldwide landscape and changes in cross-strait relations, Kinmen has been transformed from a high-alert military fortification to a famous group of islands that attract many tourists. In the last few years, the issue of climate change has increased the public's environmental awareness. In dedication to this issue, Kinmen is aggressively pursuing the construction of an energy-efficiency management network. As the current overall power supply for the Kinmen mainly from thermal power, Kinmen is hoping that by developing greener sources of energy it can play a role in the worldwide campaign to address the problems of global warming. In order to achieve the goal, the first focus should be on the best method of making good use of the natural resources of the islands - solar and wind power - and the integration of these natural resources with the unique resource of the islands - military installations. Kinmen needs to rethink the application and management of the regeneration of the abandoned military installations. By applying the approach proposed in this paper, Kinmen could develop a renewable energy scheme with distributed power systems to replace the centralized power plants. In addition to the unique characteristics of Kinmen's existing ecology and cultural history, the feasible development of renewable energy sources by integration with surplus military installations will convert Kinmen into an area with the unique combined characteristics of environmental education and tourism. © 2011 Elsevier Ltd.
