In the trench warfare of World War I, soldiers could use grenades to take out machine gunners without ever revealing themselves to the enemy. Thanks to mechanical ignition systems that made the weapons relatively practical and safe, grenades took their place as an indispensable element in modern ...

U-Boats:Brainchild of the two World Wars, U-boats are considered one of the pioneering developments in naval warfare. During the wars, they were indispensable and intimidating components of Germany’s and Britain’s maritime fleet. The typicality in their design was very different from modern, s...
The microstripdipole antennais a thin microstrip conductor and is placed on the actual part of the substrate & it is covered totally with metal on one face known as the ground plane. These antennas are used in digital communication devices like computers & the nodes for WLAN. The width of t...
Most of the modern devices use sensors to monitor and control various physical quantities like pressure, temperatures, humidity, light intensity, direction, etc. One of such sensors, used to measure the acceleration of the devices, is called the accelerometer sensors. ...
(depending on the heading requirement) – 3 magnetometers.IMUs are used to maneuver modern vehicles such as aircraft, missiles, unmanned aerial vehicles, satellites, etc. In navigation systems, the data provided by the IMU is entered into a processor that uses it to calculate altitude, position...
Computer’s history can trace back to the Abacus, a calculating tool of ancient times, which eventually gave way to the development of the computer. The very first mechanical computer was developed in the 1820s by Charles Baggage, credited as the Father of the “Modern Computer.”” Later, ...
Especially in the millimeter-wave band, it is the most powerful solid-state device in modern times, which can work in continuous waves or pulse. The disadvantage is that the noise is slightly higher than that of electron transfer devices. Avalanche oscillators and lock-in amplifiers made of ...

and the era of modern military fortification opened. The principle governing the design of the new forts constructed all over Europe was that the wholebuildingshould be concentrated in one compact block. Its low walls could then be defended all around byartillery, the guns being mounted onbastion...
