What are Spectral lines? What are the fundamentals of electronics? What do you mean by sextant? What detector is used to pick up the x-rays in hospitals? What is a spectrum ? What is the expanded form of LASER? What are the reasons for preferring diode lasers as light sources for opti...
What are Spectral lines? What is the law of reflection? What is the electric power of a lamp that carries 1 A at 120 V? What happens to the brightness of a light bulb when the current flowing through it decreases? What is power?
PAM4 doubles the network interface rate by upgrading the internal electrical chip of the optical module. Fortunately, the existing network control chips (for example, X86 chips) and the intra-board or inter-board interfaces (for example, SerDes interfaces) of high-end devices are able to proces...
To perform fragment analysis on a CE system, primers must be designed that flank the region of interest. Fluorescent dyes are attached to the primers, and the fragments are amplified by PCR before electrophoresis. To prepare for capillary electrophoresis, a spectral calibration with the ...
Spectral graph convolutional networks.Spectral GCNs are based on graph signal filters. They define the spectral domain of data based on a mathematical transformation called the graph Fourier transform. Recurrent neural networks (RNNs).RNNsare a type of artificial neural network that uses sequential or...
Engineers and technicians are also very concerned about distortion of the message modulated onto a carrier. Third-order intermodulation (two tones of a complex signal modulating each other) can be particularly troublesome because the distortion components can fall within the band of interest, which ...
(the spectral lines are blueshifted by the Doppler effect) while the other is receding (lines redshifted), a clear indication that the disk is rotating. The rotation speed is about 550 kilometers per second or 1.2 million miles per hour. Such a high rotation speed is evidence that there ...
Though the official jury is still out, there are hints that we may be right. For example, bridge engineers are now saying that the design is obsolete. Yet the bridge is only 25 years old. (There are 60 more like it still in use in Connecticut alone.) Did the designers of this ...
Almost 200 years later, Gustav Kirchhoff and Robert Bunsen showed that spectral lines are due to chemical elements in objects. Kirchhoff was also able to theorize about an object that absorbs all light and does not reflect any color. This led him to believe that there may be an object that...
CMOS sensors are significantly cheaper than CCDs, as they can be manufactured using semiconductor equipment. Furthermore, their digital circuitry and lower voltage operation substantially reduce power consumption (<1/3 the power of CCD), making them ideal for battery-powered devices.5...
