An earthing system (UK and IEC) or grounding system (US) connects specific parts of an electric power system with the ground, typically the equipment's conductive surface, for safety and functional purposes. [1] The choice of earthing system can affect the safety and electromagnetic compatibility of the installation.
An active protection system (APS) is a system designed to actively prevent certain anti-tank weapons from destroying a vehicle. Countermeasures that either conceal the vehicle from, or disrupt the guidance of an incoming guided missile threat are designated soft-kill active protection measures.
The 3B20E was created to provide a cost-reduced 3B20D for small offices that did not expect such high availability. It consists of a virtual "emulated" 3B20D environment running on a stand-alone general purpose computer; the system was ported to many computers, but primarily runs on the Sun Microsystems Solaris environment.
As of 31 March 2022, L&T has 93 subsidiaries, 5 associate companies, 27 joint ventures and 35 joint operations. [18]L&T – Construction Equipment Limited: having its registered office at Mumbai, India and focusing on construction equipment and mining equipment, L&T-Komatsu Limited [19] was a joint-venture of Larsen and Toubro, and Komatsu Asia Pacific Pte Limited, Singapore, a wholly owned ...
The T-carrier is a hardware specification for carrying multiple time-division multiplexed (TDM) telecommunications channels over a single four-wire transmission circuit. It was developed by AT&T at Bell Laboratories ca. 1957 and first employed by 1962 for long-haul pulse-code modulation (PCM) digital voice transmission with the D1 channel bank.
For example, three identical systems starting to function properly at time 0 are working until all of them fail. The first system fails after 100 hours, the second after 120 hours and the third after 130 hours. The MTBF of the systems is the average of the three failure times, which is 116.667 hours.
Heavy Equipment Transporter System (HETS) is the name of a U.S. Army logistics vehicle transport system, the primary purpose of which is to transport the M1 Abrams tank. It is also used to transport, deploy, and evacuate armored personnel carriers , self-propelled artillery , armored bulldozers , and other heavy vehicles and equipment.
Unlike an I-beam, a T-beam lacks a bottom flange, which carries savings in terms of materials, but at the loss of resistance to tensile forces. [5] T- beam designs come in many sizes, lengths and widths to suit where they are to be used (eg highway bridge, underground parking garage) and how they have to resist the tension, compression and shear stresses associated with beam bending in their ...
