A fluorescent bulb consuming the same amount of power as an incandescent bulb will produce three to five times more light, and it does this by using a phosphor, a chemical that glows when exposed to electromagnetic energy. (The term “phosphor” should not be confused with phosphorescenc[r]

Die Casting. Manually operated casting machines were patented as early as 1849 (Sturgiss) and 1852 (Barr) in an effort to satisfy the insatiable demands of a growing reading public by way of rapidly cast lead type. These early inventions led to Ottmar Mergenthaler's Linotype, an automatic[r]

In this paper, we tried to address a very effective technique called Wavelet thresholding for denoising, as it can arrest the energy of a signal in few energy transform values, followed by Marker controlled Watershed Segmentation.

151 The nonlinear scattering usually arises from the formation of two types of scattering centers after photo-excitation of the G-Polymer solutions. At higher pump fluence, the excitation energy absorbed by the graphene flakes easily transfers the thermal energy to the poly[r]

Combining fluorescence and force measurement
In contrast to the above examples, there have been relatively few experiments that measure single-molecule forces and flu- orescence at the same time. This is predominantly because of the problems of detecting single-molecule fluorescence where a hig[r]

two pumps are generated from different laser source; therefore, their phase is not locked. Moreover, in order to maintain the same polarization direction, we need to use polarization controller (PC) or polarization maintaining fiber (PMF) to keep the two lightwaves have the same polarization dir[r]
