CoPtP alloys have been grown by electrochemical process in an external magnetic field in order to enhance the perpendicular magnetic properties. The coercivity and squareness of the alloys were improved as the external magnetic field was increased. The alloys have a mosaic microstructure consisting of grains with size in the range of 10–15nm. The grains are separated by highly well defined 1–2nm grain boundaries. The alloys exhibit a columnar microstructure with a hcp [002] fiber texture. The films exhibit significant perpendicular magnetic anisotropy and permanent magnetic properties in the perpendicular direction, with coercivity of up to 6.1kOe and squareness of up to 0.9.
Motion artifacts can degrade the quality of data measured. In this paper, we suggest a capacitive sensor application which is able to be fabricated easily and employed for adaptive filtering. When the motion artifacts occur, the capacitance varies as well. Thereby, the capacitance data coincide with the motion artifacts. The capacitance data synchronous with the motion artifacts and the corrupted blood pressure signal were applied to the adaptive digital filter so that motion artifacts in blood pressure signal managed to be removed successfully.
In this study, a new method for acupuncture point detection using the impedance measurement system based on the PSM (Phase Space Method) is presented. The developed device has been developed as detectors for acupuncture points which are used for diagnosis and treatment in acupuncture. In this system, multi-frequency current injection and voltage measurements are both performed by the surface electrodes, which are controlled by a microcontroller. Also, the microcontroller process continuous time demodulation of the modulated signal by multi frequency components using the adaptive notch filter. After that, PSM is applied about each frequency using an acupuncture equivalent model which is proposed in the pre-study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
