A launch loop or Lofstrom loop is a design for a belt-based maglev orbital launch system that would be around 2000 km long and maintained at an altitude of up to 80 kilometres (50 mi). Vehicles weighing 5 metric tons would be electromagnetically accelerated on top of the cable which forms an acceleration track, from which they would be ...

System 2000 [1] [2] [3] (S2K) [4] [5] is a hierarchical database management system (DBMS). [2] Although not a relational database, S2K does have SQL support. [6] In 2007 it was noted that, while still 'running on systems cranking away in back rooms across the U.S.' it has a problem: "there's little curriculum coverage anymore at universities teaching computer science."
A system of bodies may have internal kinetic energy due to the relative motion of the bodies in the system. For example, in the Solar System the planets and planetoids are orbiting the Sun. In a tank of gas, the molecules are moving in all directions. The kinetic energy of the system is the sum of the kinetic energies of the bodies it contains.
In 1900, Max Planck derived the average energy ε of a single energy radiator, e.g., a vibrating atomic unit, as a function of absolute temperature: [24] = / (), where h is the Planck constant, ν is the frequency, k is the Boltzmann constant, and T is the absolute temperature. The zero-point energy makes no contribution to Planck's original ...
On 19 June 2000, STK announced the release of an upgrade kit, known as the 40mm Automatic Grenade Launcher Air-Bursting System (40mm AGL-ABS). [2] Upgrades consist of the electronic fire control system, the gun computer, the muzzle programming coil as well as the optical sighting system.

The STK 50 MG, formerly known as the CIS 50MG, [a] is a gas-operated, air-cooled, belt-fed heavy machine gun developed and manufactured by Chartered Industries of Singapore (CIS, now ST Kinetics) in the late 1980s, in response to a request by the Singaporean Defence Ministry to replace the 12.7mm Browning M2HB machine guns then in ubiquitous service with the Singapore Armed Forces (SAF).
