A machine learning approach has been implemented to measure the electron temperature directly from emission spectra of a tokamak plasma. This utilized neural network (NN) trained on dataset 1865 time slices operation DIII-D using extreme ultraviolet/vacuum ultraviolet spectroscopy matched with high-accuracy divertor Thomson scattering measurements temperature, Te. NN is shown be particularly go...
We describe the energy budget of a coronal mass ejection (CME) observed on 1999 May 17 with Ultraviolet Coronagraph Spectrometer (UVCS). constrain physical properties CME's core material as function height along corona by using spectra taken single-slit coronagraph spectrometer at heliocentric distances 2.6 and 3.1 solar radii. use plasma diagnostics from intensity ratios, such O VI doublet lin...
background: wearing spectacles is the most common approach in correcting the refractive errors worldwide. due to harmful effects of overexposure to solar ultraviolet radiations, the usage of multi-layer coatings in ophthalmic lenses has recently been increased. these lenses can reduce the reflections and hence increase the transmission of visible light; they can also decrease the transmission o...
The best performance of the phosphor Li(2)SrSiO(4): Eu(2+), Ce(3+) in terms of luminescence efficiency (LE), color rendering index (CRI) and color temperature (Tc) for light-emitting diode application was optimized with combinatorial approach. The combinatorial libraries were synthesized with solution-based method and the scale-up samples were synthesized with conventional solid-reaction method...
