The application of Ca5B2SiO10:Eu3+ and YAl3B4O12:Ce3+,Mn2+ in dual-layer remote phosphor to enhance lumen output and color quality of WLEDs
This study proposes a dual-layer remote phosphor structure, comprised of a
green or a red phosphor layer and a yellow YAG:Ce3+ phosphor layer, to
enhance color rendering index (CRI) and color quality scale (CQS) of white
light-emitting diodes…

Quantitative approach for reclassification of the spatial cluster of archipelagos in Maluku Province for the basis of forest development
In natural resource management, it is necessary to group regions based on the
similarity of their spatial and non-spatial characteristics, to efficiency and
effectiveness Therefore, this study describes the re-grouping of the twelve
island…

Lower and upper bound intercept probability analysis in amplifier-and-forward time switching relaying half-duplex with impact the eavesdropper
In this paper, we proposed and investigated the amplifier-and-forward (AF)
time switching relaying half-duplex with impact the eavesdropper. In this
system model, the source (S) and the destination (D) communicate with each
other via a helping of…
