T-TRAK (all letters capitalized) is a modular model railroad system based on standards for module size, track placement, track interface, and electrical connections. The standards allow for a wide range of flexibility in design yet still maintain interoperability with all modules built per the standards. The popularity of T-TRAK is worldwide ...
Zambia: 5 T-54s were ordered in 1975 from the Soviet Union and delivered in 1976. 20 T-55s were ordered in 1980 from the Soviet Union and delivered in 1981 (part of a $72–100M deal). 60 T-55s, PT-76s and Type 59s were in service in early 2001 and early 2003. 10 T-55s were in service in 2004 and 2006.
A V5.1 interface relates to a single aggregate E1 (2 Mbit/s) link between a multiplexer and an exchange. V5.2 ( ETS 300 347-1) which provides for concentration where there are not enough bearer channels in the aggregate link (s) to accommodate all subscribers at the same time. A single V5.2 interface can control up to 16 E1 links at once and ...
A rack and pinion is a type of linear actuator that comprises a circular gear (the pinion) engaging a linear gear (the rack ). Together, they convert between rotational motion and linear motion. Rotating the pinion causes the rack to be driven in a line. Conversely, moving the rack linearly will cause the pinion to rotate.

Its main use is in utilities such as electric and water companies. Usage in other industries is not common. It was developed for communications between various types of data acquisition and control equipment.
The transformation is easy to describe if the circuit is wholly constructed out of 2-input NAND gates (a functionally-complete set of Boolean operators): assign every net in the circuit a variable, then for each NAND gate, construct the conjunctive normal form clauses (v 1 ∨ v 3) ∧ (v 2 ∨ v 3) ∧ (¬v 1 ∨ ¬v 2 ∨ ¬v 3), where v 1 ...
The Improved Outer Tactical Vest ( IOTV) is an enhanced version of, and a replacement for, the older Outer Tactical Vest (OTV) component of the Interceptor Multi-Threat Body Armor System, as fielded by the United States Army beginning in the mid-2000s.
