Excellent color quality of phosphor converted white light emitting diodes with remote phosphor geometry
The advantage in using a remote phosphor design in a WLED package is
the superior luminous flux to that of the conformal and in-cup phosphor
geometries. However, the disadvantage is its color quality which is lower than the results from the other…

Modifying Hamming code and using the replication method to protect memory against triple soft errors
As technology scaling increases computer memory’s bit-cell density and
reduces the voltage of semiconductors, the number of soft errors due to
radiation induced single event upsets (SEU) and multi-bit upsets (MBU) also increases. To address this,…
