Electromagnetic pulse

magnetic field. Using strong radio waves/signals, the computer searches for the frequencies for specific types of atoms. Even after the radio signals are turned off the atoms will still emit energy that they have absorbed. The computer then reads the pulses of energy that the atoms are emitting and constructs a 3D image of the scanned area. MRIs also allow physicians to create 3D images of larger sections of molecules and reconstruct areas where the tissue is too soft for x-rays to pick up.…

crack resistance in addition to the other properties of auxetics mentioned earlier [10]. Non-auxetic foams are manufactured to be auxetic through a process of compression on all axes and thermal deformation [3] as well as soaking the foams in electromagnetic fluids to alter their physical properties…

They are all simply electromagnetic radiation of different wavelengths. For fiber optics with glass fibers, infrared light is used for fiber optics because it contains wavelengths longer than visble light, which is around 850 to 1150 nm. (As seen on the diagram) Infrared is used…

Acoustic wave therapy is non-invasive and employs acoustic waves to stimulate the patients’ tissues. The procedure is done with the CELLACTOR® SC1. This system uses extracorporeal pulse activation technology or EPAT. The CELLACTOR® SC1 has two hand pieces that operate differently. C-ACTOR utilizes a high intensity electromagnetic system. Acoustic planar waves are generated and have an effect on both cells and their metabolism. The permeability of the cells increases, allowing for easier escape…

u know that the first message of Morse code was sent to someone 40 miles away in May 1844, the message sent was "What hath God Wrought?” My name is Shae Phillips and today I will be telling you who, what, when, where and why Morse code was invented and how it changed the economy, society and what were the short and long term effects and how revolutionised the future. In 1838 Morse code was invented by Samuel Morse. Morse then further introduced a working telegraph in 1844 which allowed users on…

book. So, first off, I would like to say one word: zombies! Yes, it’s another zombie book, but this one has a unique twist. Rather than being undead, these zombies are still alive; they just eat people. See, it all began on day when a giant electromagnetic pulse flooded the earth causing all adults, ages 20-50, to drop dead on the spot. While many people died, all youth were turned into flesh eating zombies, but the twist is that these kids are still alive, though they’ve lost all traces of…

A ray of light travels in a straight line. This is true until it passes from one medium (eg. air) into another medium (eg. glass) of a different optical density. When this happens, the ray of light changes speed causing it to bend either towards or away from the normal which is an imaginary line at 90 to the interface between two mediums. This is called refraction. How much it bends depends on the refractive indices of the two mediums which is a ratio of the speed of light in one medium…

1000 books or 16 high-definition TV channels per second. That means that the HAUV would be capable of transmitting super high-quality sonar images, several HD video feeds and HD images, all at the same time [3]. It can be used in rich, intensive electromagnetic environments with no significant effect to the transmission quality or rate. Since it uses only light, it poses a very low security risk. The only way to compromise the security of a fiber optic cable is to intercept the light emission…

invention of the telegraph and developed from then on to become the most important and powerful medium of communication, through the work of influential people, and most of which, Edwin Howard Armstrong. Radio is the exchange of sound messages and electromagnetic signals…

The 5th Wave opens after aliens have invaded and attacked Earth. First, electricity was destroyed with an electromagnetic pulse; then the coasts were enveloped by rising seas; next, an Ebola-like plague wiped out much of the population; then, what were effectively alien sleeper cells were activated, and the few remaining humans can't be trust anyone. I know what you're thinking: Another post-apocalyptic novel? The 5th Wave isn't just another post-apocalyptic novel. It's character-driven, it's…
