We experimentally demonstrate a 750 Mb/s real-time visible light communication(VLC) system based on non-return-to-zero on–off keying modulation by employing single commercially available monochromatic lightemitting diodes. To enhance the 3-d B bandwidth of the VLC link, we propose a low-complexi...
1. A method for detection and wavelength discrimination of a monochromatic light beam comprising; installing at least one detector pair consisting of a first photo detector with progressively increasing active area per unit distance in one direction and a second photo detector aligned with the first...
based on their characters. We have a Mimic for the Dungeon Master, a mouse for the guy whose character had a pet mouse, a bear for the druid who turned into a bear sometimes, a shield for the asimar who used his shield to light our paths, a mug of beer for the dwarf...
The speed of light in a transparent medium is 0.6 times that of its speed in vacuum. What is the refractive index of the medium? View Solution Monochromatic light of frequency6.0×1014Hzis produced by a laser. The power emitted is2.0×10−3W, (a) What is the energy of a photon in ...
An experiment similar to that of Example 1 was performed by placing the light-sensitive element in a camera, and exposing it for one second to an image on a visual display terminal of an IBM Personal Computer. The element was processed as in Example 1. Upon separation of the laminate after...
The neutron subthreshold fission cross section of $sup 240$Pu has been measured from 500 to 10 000 eV using the Oak Ridge electron linear accelerator neutr... GF Auchampaugh,CD Bowman - 《Physical Review C》 被引量: 24发表: 1975年 Possible observation of light neutron nuclei in the alpha...
LED curing light (LUX E, Guilin Woodpecker, Guilin, Guangxi, China) was used to cure each composite for 20 s. The final finishing of composite restorations was performed using white stone bur (Shofu, Kyoto, Japan) and Soflex disc (3M, Minnesota, USA). Figure 1. The dimensions of Class ...
The blue light radiation played a key role in the TP uptake of the tested plants. The N removal rates of plants were relatively lower (10–40%), limited by the low COD content. The S. trifolia exhibited the highest efficiency, and red light promoted the removal of TN and NO3−-N, ...
i would say this a lightweight comforter, which is perfect being from texas since it never really gets cold here. the small details with the tufted areas gives it a classy look. it comes in a shoulder bag, made of material, so easy to carry if needed. the accent pillow is a great ...
(1) means for measuring the time interval required to send a laser pulse into the sample and receive a return signal caused by light scattered therein and (2) means for measuring the amplitude of the return signal, the distance of the sample from the apparatus 10 as well as the pollutant...
