We have carried out experimental and numerical analyses for reconstruction of permittivity distribution using a pair of long distance small size electrodes and additional arc electrodes. A reconstruction method for permittivity distribution that uses a genetic algorithm and numerical analysis (finite element method) based on measured capacitance has been proposed and investigated. However, the conventional method had a problem in accuracy. In this paper, the reconstruction method has been improved by using a Parameter-free Genetic Algorithm(PfGA) based on measured capacitance and electric potential. In addition, we have evaluated the fitness function with PfGA. © 2016 The Institute of Electrical Engineers of Japan.

We evaluated the temperature change of facial parts as affected by mental work-load (MWL) using infrared thermography. Under MWL, autonomic nerves are active, and the skin surface temperature changes with muscular contraction. In particular, the nasal part of the face experiences the most intense change. Based on this, in previous studies MWL was evaluated by using nasal skin temperature. However, we considered whether other parts of the face experience temperature change under MWL. Therefore, in this study, to identify which other parts of the face experience temperature change, we performed an experiment to acquire facial thermal images when subjects perform a mental arithmetic calculation task. Our results indicate that, in addition to the nasal part, the temperatures around the lips and cheek might also increase under MWL. © 2016 The Institute of Electrical Engineers of Japan.

Real-time real-life oriented DSP Lab modules

2015 122nd ASEE Annual Conference and Exposition

作者： Ryan, Isaiah I. Cramer, Aaron Lin, Ying Western Washington University Electronics Engineering Technology/Electrical Engineering program United States Western Washington University Engineering and Design Department United States

In this paper, we present a sequence of engaging lab exercises that implement real-time real-life signal/data acquisition, analysis, and processing using MatLab, LabView, and NI myDAQ. Examples of these signals include real-time human voice and music signals. These lab modules are designed to enhance the existing lab components in the digital signal processing and/or digital communications curriculum in an Electronic engineering technology (EET) program at Western Washington University. The lab topics cover fundamentals of digital signal processing (DSP) such as real-time data acquisition, sampling, time-domain and frequency-domain analysis, and digital filtering. Noise analysis and removal examples have been also introduced in the lab modules. Moreover, advanced DSP techniques such as speech recognition have been incorporated in the labs to implement a voice-controlled DSP application as well. Besides serving the EET curriculum, the labs developed in this work can be used as effective outreach tools. For instance, we have adopted these labs as demos to groups of 5thgraders of an annual Compass to Campus program in our institution to promote engineering and technology to young minds. These newly developed engaging lab demos will help to further attract and spark young students' interests in engineering and technology. © American Society for engineering Education, 2015.

Ultrafast optical pump - optical probe and optical pump - terahertz probe spectroscopy were performed on vanadium dioxide (VO2) and vanadium sesquioxide (V2O3) thin films over a wide temperature range. A comparison of the experimental data from these two different techniques and two different vanadium oxides, in particular a comparison of the electronic oscillations generated by the photoinduced longitudinal acoustic modulation, reveals the strong electron-phonon coupling that exists in the metallic state of both materials. The low energy Drude response of V2O3 appears more susceptible than VO2 to ultrafast strain control. Additionally, our results provide a measurement of the temperature dependence of the sound velocity in both systems, revealing a four- to fivefold increase in VO2 and a three- to fivefold increase in V2O3 across the phase transition. Our data also confirm observations of strong damping and phonon anharmonicity in the metallic phase of VO2, and suggest that a similar phenomenon might be at play in the metallic phase of V2O3. More generally, our simple table-top approach provides relevant and detailed information about dynamical lattice properties of vanadium oxides, opening the way to similar studies in other complex materials.

Rejection of aliases for a direct sampling mixer with complex poles

IEEJ Transactions on Electronics, Information and Systems

引用

IEEJ Transactions on electronics, Information and Systems 2016年第1期136卷 60-67页

作者： Imai, Hiroyuki Wada, Kazuyuki Electrical Engineering Program Graduate School of Science and Technology Meiji University 1-1-1 Higashi-Mita Tama-ku Kawasaki214-8571 Japan Department of Electronics and Bioinformatics School of Science and Technology Meiji University 1-1-1 Higashi-Mita Tama-ku Kawasaki214-8571 Japan

This paper proposes the design scheme of direct sampling mixer (DSM) by which unallowable amplitude characteristics due to aliases spreading over relatively broad band is suppressed. It is pointed out that the periodic frequency characteristic of a stage processing decimated signal causes decrease of attenuation in the stopband of the DSM, and an IIR section with a low decimation rate is employed as the first stage. A DSM the amplitude characteristic of which falls into the spectrum mask for IEEE 802.11 is designed as an example. Simulation results show that the designed DSM satisfies specification widely in not only the passband but also the stopband. It is confirmed that gradual decimation approach or use of a non-decimated section for the first stage is effective. © 2016 The Institute of Electrical Engineers of Japan.
