Endovascular coiling is an endovascular treatment for intracranial aneurysms and bleeding throughout the body. The procedure reduces blood circulation to the aneurysm through the use of microsurgical detachable platinum wires, with the clinician inserting one or more into the aneurysm until it is determined that blood flow is no longer occurring within the space.
The V-boats were a group of nine United States Navy submarines built between World War I and World War II from 1921 to 1934 under authorization as the "fleet boat" program.. The term "V-boats" as used includes five separate classes of submarines: large, fast fleet submarines (V-1 through V-3), large long-range submarines (the minelayer V-4 and two submarine cruisers V-5 and V-6) and three ...
Rogowski coil. A Rogowski coil is a toroid of wire used to measure an alternating current I(t) through a cable encircled by the toroid. The picture shows a Rogowski coil encircling a current-carrying cable. The output of the coil, v(t), is connected to a lossy integrator circuit to obtain a voltage Vout(t) that is proportional to I(t).
Cohen–Daubechies–Feauveau wavelets are a family of biorthogonal wavelets that was made popular by Ingrid Daubechies. [1][2] These are not the same as the orthogonal Daubechies wavelets, and also not very similar in shape and properties. However, their construction idea is the same. The JPEG 2000 compression standard uses the biorthogonal Le ...

The S5G reactor plant floats in a tank of water to simulate the engine room of a submarine. The S5G reactor was a prototype naval reactor designed for the United States Navy to provide electricity generation and propulsion on submarines. The S5G designation stands for: S = Submarine platform. 5 = Fifth generation core designed by the contractor.
Electromagnetic coil. The magnetic field lines (green) of a current-carrying loop of wire pass through the center of the loop, concentrating the field there. An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil (spiral or helix). [1][2] Electromagnetic coils are used in electrical engineering, in applications ...
A Tesla coil is a radio frequency oscillator that drives an air-core double-tuned resonant transformer to produce high voltages at low currents. [4][7][8][9][10][11] Tesla's original circuits and most modern coils use a simple spark gap to excite oscillations in the tuned transformer. More sophisticated designs use transistor or thyristor [7 ...
