Continuous speech segmentation using local adaptive thresholding technique in the blocking block area method
Continuous speech is a form of natural human speech that is continuous
without a clear boundary between words. In continuous speech recognition, a segmentation process is needed to cut the sentence at the boundary of each word. Segmentation becomes…

Influence of Ba[Mg2Al2N4]Eu2+ phosphor particle size on optical properties of the 6000K CPW-LEDs
In this paper, we consider the red phosphor Ba[Mg2Al2N4]Eu2+ as
the novel recommendation for improving the optical properties of the 6000K conformal packaging WLEDs (CPW-LEDs). For this purpose, we investigate the influence of the Ba[Mg2Al2N4]Eu2+…
