Large amplitude microwave emission and reduced nonlinear phase noise in Co2Fe(Ge0.5Ga0.5) Heusler alloy based pseudo spin valve nanopillars

We have studied microwave emission from a current-perpendicular-to-plane pseudo spin valve nanopillars with Heusler alloy Co2Fe(Ga0.5Ge0.5) electrodes. Large emission amplitude exceeding 150 nV/Hz^0.5, partly owing to the large magnetoresistance, and narrow generation linewidth below 10 MHz are observed. We also find that the linewidth shows significant dependence on the applied field magnitude and its angle within the film plane. A minimum in the linewidth is observed when the slope of the frequency versus current becomes near zero. This agrees with theoretical prediction that takes into account non-linear phase noise as a source for linewidth broadening

Effect of short-term temperature treatment to clusters on anthocyanin and abscisic acid content in the peel of 'Aki Queen' grape

The effect of short-term low and high temperature treatment to clusters before and after the onset of color development on anthocyanin and abscisic acid (ABA) content in the peel of 'Aki Queen' (Vitis labruscana L.), a tetraploid grape cultivar with red peel was investigated. Grape clusters were exposed to different temperature conditions, either from the beginning of the berry softening to the onset of color development, 47 to 56 days after full bloom (DAFB), or from the onset of color development onwards for 10 days, 56 to 66 DAFB. Low-temperature (2-5 °C lower than control) treatments in both, 47 to 56 DAFB and 56 to 66 DAFB had the tendency to increase anthocyanin concentration and the concentration in the peel was higher than that in the control. The difference in the ABA content after low and high temperature treatment in the 47 to 56 DAFB suggests that temperature from the beginning of berry softening to the onset of color development might affect the ABA content of the peel. On the other hand, treatment from the onset of color development onwards for 10 days might affect the anthocyanin concentration, but the effect on ABA content is relatively low. These results suggest that temperature-dependent accumulation of anthocyanin during maturation correlate with ABA content at the onset of color development in 'Aki Queen' grape.

A Research of Basic Energy Reduction Approach Using PV Power Smoothing EV Storage System and LED Simple Circuit for Create Green Innovation

In general, Light Emitting Diode (LED) is low power consumption, and Photovoltaic (PV) generation of Renewable Energy is effective as energy creation. However, LED applications have a problem of LED Circuit Radiation Noise and PV generation applications have a problem of the Output Power fluctuation in the weather. This paper will be proposed as an especial approach of the energy reduction to contribute to the realization of the low carbon society in the world. In this research, without using Common Mode Choke (CMC) Noise Cut filter, the Radiation Noise reduction result in World Standard Guideline by the selection of a simple circuit of the most effective LED lighting of various power reduction methods have been confirmed by the examinations. Additionally, in order to investigate the lighting specification, the simple Lighting evaluation equipment has been developed. As an energy fluctuation reduction research, the new control system of the PV fluctuation electric power using EV battery charge-discharge electric power that is able to be easily connected with a Power Conditioning System (PCS) input is proposed. A simulation result using the actual PV generator output data is provided to confirm the effectiveness of Simple Moving Average (SMA) method. Moreover, the outline of a new large area monitoring control GIS system for the implementation of the PV generator power prognostication without the weather estimation is introduced.九工大・マレーシアプトラ大学国際合同シンポジウム: International Symposium on Applied Engineering and Sciences (SAES), September 30- October 1, 2013, Universiti Putra Malaysia, Malaysi

Bifurcations associated with sub-synchronous resonance

This paper describes a set of results of detecting nonlinear phenomena appearing in a turbine generator power system with series-capacitor compensation. The analysis was based on the Floquet theory as well as the Hopf bifurcation theorem. After the first Hopf bifurcation, the stable limit cycle bifurcates to a stable torus and an unstable limit cycle which connects to a stable limit cycle by a supercritical torus bifurcation. The stable limit cycle joins with an unstable limit cycle at a cyclic fold bifurcation. This unstable limit cycle is connected to the second Hopf. It has been also numerically demonstrated that such a strange sequence of periodic orbits is created by a q-axis damper winding.published_or_final_versio

Comparative study of excitonic structures and luminescence properties of Bi4Ge3O12 and Bi12GeO20

Published in physica status solidi (b), Vol. 245, No. 12, pp2733-2736, 2008.Bi12GeO20 crystals have been performed, in addition to relativistic molecular orbital calculations. Both materials consist of the same elements but form different crystal structures. Based on the obtained results, the excitonic reflection structures and luminescence properties of Bi4Ge3O12 and Bi12GeO20 are discussed in comparison with each other.Bookphysica status solidi (b). 245(12):2733-2736 (2008)journal articl

Performance of a Low Noise Front-end ASIC for Si/CdTe Detectors in Compton Gamma-ray Telescope

Compton telescopes based on semiconductor technologies are being developed to explore the gamma-ray universe in an energy band 0.1--20 MeV, which is not well covered by the present or near-future gamma-ray telescopes. The key feature of such Compton telescopes is the high energy resolution that is crucial for high angular resolution and high background rejection capability. The energy resolution around 1 keV is required to approach physical limit of the angular resolution due to Doppler broadening. We have developed a low noise front-end ASIC (Application-Specific Integrated Circuit), VA32TA, to realize this goal for the readout of Double-sided Silicon Strip Detector (DSSD) and Cadmium Telluride (CdTe) pixel detector which are essential elements of the semiconductor Compton telescope. We report on the design and test results of the VA32TA. We have reached an energy resolution of 1.3 keV (FWHM) for 60 keV and 122 keV at 0 degree C with a DSSD and 1.7 keV (FWHM) with a CdTe detector.Comment: 6 pages, 7 figures, IEEE style file, to appear in IEEE Trans.
