Qin Xin við tveimum nýggjum vísindaligum greinum

Í august 2015 gav Qin út tvær vísindaligar greinar, sum eru at finna í tveimum ymiskum altjóða tíðarritum.

Niðanfyri er stutt lýsing var hesum báðum á enskum.

The first one is the joural article “A Novel Generator for High-voltage Bipolar Square Pulses with Applications in Sterilization of microorganism” published in IEEE Transactions on Dielectrics and Electrical Insulation, Volume: 22, Issue: 4, pages: 1887 – 1895, August 2015. In this paper, we propose and design a novel generator for the high voltage square pulses with the changeable polarities in order to reach the requirements and the needs for the intended experiments on sterilization of microorganism. The major component of our circuits is a non-trivial combination between a half bridge Marx generator and an H bridge in series, combining with the DSP control unit, which can adjust the voltages, frequencies, pulse widths and polarities, and also tolerate various loads. The effectiveness and correctness of our proposed circuit and methodologies have been verified and demonstrated by both PSIM simulation results and our own prototype. In this work, we also show the stability and reliability of the pulse generator we proposed in terms of various load conditions and operation safety respectively. We hope that our work will stimulate the further investigations on design and analysis of pulse generators with a focus on modularization and miniaturization. Note also that this is a joint work with our former visiting professor Lan Xiong at Chongqing University, China.

Another one is an edited book “Algorithm and Theory for Robust Wireless Sensor Networks 2014”: a speical issue of International Journal of Distributed Sensor Networks. The main focus of this special issue is devoted to a deeper understanding of the fundamental protocols, algorithms, modeling, and analysis techniques for robust wireless sensor networks, which exhibit substantial vulnerability when compared to other networks. Recently there are so many papers developing new techniques in wireless sensor networks. However, we believe that the algorithmic and theoretical issues in the robust wireless sensor networks were not fully explored. In this annual special issue, totally we have received 25 submissions, coming from different countries all around the globe in response to call for paper. We also invited some extended best papers from 2014 IET International Conference on Frontiers of Internet of Things (FIT), which was held in Hsinchu, Taiwan, on December 4–6, 2014. Each accepted article has been reviewed by at least three reviewers. In the end, nine articles are revised and selected for publishing in this annual special issue. We believe that the accepted papers present the most up-to-date progress in algorithms and theory for robust wireless sensor networks with respect to different networking problems.
