Adjustable Plasmonic Core–Shell Nanoparticles for Personalized Color Vision Correction
Advanced Engineering Materials, EarlyView.This study introduces a personalized solution for correcting color vision deficiency (CVD) by embedding tunable core‐shell metal nanoparticles—a common nanotechnology—into contact lenses. By customizing the nanoparticles’ optical properties to filter specific wavelengths, these lenses address individual visual impairments, enhancing color ...

Advanced Engineering Materials, EarlyView.Laser powder‐bed fusion (L‐PBF) can produce dense WE43 magnesium alloy parts, but their mechanical properties are limited by a nonhomogeneous microstructure. This study investigates the effects of varying direct aging (T5) and artificial age‐hardening (T6) conditions on microstructure and strength. Optimized T6 treatment significantly improves strength

Advanced Engineering Materials, EarlyView.Herein the metal‐to‐insulator transition is investigated when depositing vanadium dioxide (VO2) on glass or aluminum‐doped zinc oxide (AZO). O2 flow tuning during the deposition and additional post annealing are effective to control the metal‐to‐insulator transition. However, the VO2/AZO/glass stack reveals an increase in the transition temperature and

On the analysis of the phosphorescence spectrum of [PDF]
Journal of Physics B: Atomic, Molecular and Optical Physics, 1996 The phosphorescence spectrum of , recently obtained in an alcane matrix at low temperature, has been modelled by means of semi-empirical quantum-chemical calculations. The transition is symmetry as well as spin-multiplicity forbidden. The spectrum is successfully analysed in terms of the Herzberg - Teller mechanism combined with spin - orbit ...

Spectrum Analysis of Human Pulse [PDF]
IEEE Transactions on Biomedical Engineering, 1983 Pulse spectral graphs (PSG) were obtained from pulses taken on the wrist by using electronics and computers. Energy ratio (ER) is defined as the ratio of the energy of PSG below 10 Hz to that above 10 Hz. We find that the ER for healthy persons is above 100 at all three-finger positions on both wrists, but those for sick persons are below 100 at some ...

International Symposium for Testing and Failure Analysis, 2017
Abstract We present a new, non-destructive electrical technique, Power Spectrum Analysis (PSA). PSA as described here uses off-normal biasing, an unconventional way of powering microelectronics devices. PSA with off-normal biasing can be used to detect subtle differences between microelectronic devices.

Computerized Spectrum Analysis
Applied Spectroscopy, 1970A system to automatically reduce and analyze the data on a spectrogram is in current use. The techniques used and the system are described. The system's principal components consist of a scanning densitometer with a built-on linear encoder, a 16-kc word rate analog-to-digital converter, and an IBM 1800 process computer with magnetic disk memory.

Publisher Summary Spectrum analysis transforms a displacement/time chart into an amplitude/frequency chart known as a spectrum. This analysis consists of decomposing a time-varying signal into its component pure tones. Pure tones are sinusoidal wave forms of constant frequency and amplitude.

IETE Technical Review, 2000
In the analysis of EMG signal during dynamic movement, we have proposed an estimation algorithm for the time varying parameters. The parameters correspond to less biased time varying reflection coefficients. We determine the less biased estimation using a locally quasi-stationary model and name these parameters “K-parameters”.
