A foreign key is a set of attributes in a table that refers to the primary key of another table, linking these two tables. In the context of relational databases, a foreign key is subject to an inclusion dependency constraint that the tuples consisting of the foreign key attributes in one relation, R, must also exist in some other (not necessarily distinct) relation, S; furthermore that those ...
Lima produced Mk. 2B BFK, FK and TSO and Mk. 2E FO and TSO models. These were approximately 1 cm under scale length, and have not been produced since Lima was taken over by Hornby. Bachmann Branchline introduced Mk. 2 and Mk. 2A BFK, BSO, FK and TSO models in the early 2000s, which were more detailed than the various older models. Bachmann have ...
The 4DR6 is a direct injection turbo version with 17.5:1 compression ratio and Mitsubishi TD04-1 turbocharger that produced up to 94 PS (69 kW) and 21.0kgm of torque. Both of these engines were used in large forklift trucks, as well as Canter models and the Mitsubishi J20 and J50 series Jeep.
The design staff ultimately drew up five different designs: FK 1, FK 1a, FK 2, FK 3, and FK 4. The proposals ranged in size from 3,000 metric tons (3,000 long tons; 3,300 short tons) to 7,500 t (7,400 long tons; 8,300 short tons) designed displacement and were armed with a main battery of between five and eight 15 cm (5.9 in) guns.
Appearing in November 2001, the 2KD-FTV is the 2nd generation of the KD series of engine with a smaller 2.5 L (2,494 cc) displacement and went on sale in the UK market in the 2002 Toyota HiAce producing either 66 kW (88 bhp) at 3,800rpm and 192 N⋅m (142 lb⋅ft; 20 kg⋅m) at 1,200-3,000rpm or 76 kW (102 bhp) at 3600rpm and 260 N⋅m (192 lb⋅ft; 27 kg⋅m) 1,600-2,400 rpm.
Because of the difference in techniques needed, to avoid leg fatigue, and to reduce the risk of injury, on the professional level most teams employ separate players to handle the jobs. The placekicker usually will only punt when the punter is injured, and vice versa (one player often handles both jobs in the Canadian Football League , which has ...
This algorithm creates a number between 0 and 1 that is approximately uniformly distributed in that space. If the P k of a weapon/target engagement is 30% (or 0.30), then every random number generated that is less than 0.3 is considered a "kill"; every number greater than 0.3 is considered a "no kill". When used many times in a simulation, the ...
The Frenkel–Kontorova (FK) model is a fundamental model of low-dimensional nonlinear physics. [ 1 ] The generalized FK model describes a chain of classical particles with nearest neighbor interactions and subjected to a periodic on-site substrate potential. [ 2 ]
