This paper deals with hyperspectral detection in impulsive and/or non homogeneous background contexts. In hyperspec-tral imaging applications, the detection performance of the detectors (target detection or anomaly detection like Maha-lanobis distance) is typically evaluated on Gaussian assumption. However, it is well known that hyperspectral imaging data(More)
We report on the observation of broad photoluminescence wavelength tunability from n-type gallium nitride nanoparticles (GaN NPs) fabricated using the ultraviolet metal-assisted electroless etching method. Transmission and scanning electron microscopy measurements performed on the nanoparticles revealed large size dispersion ranging from 10 to 100 nm.(More)
Indoor horticulture offers a sensible solution for sustainable food production and is becoming increasingly widespread. However, it incurs high energy and cost due to the use of artificial lighting such as high-pressure sodium lamps, fluorescent light or increasingly, the light-emitting diodes (LEDs). The energy efficiency and light quality of currently(More)
