3. BRIEF DESCRIPTION OF THE SYb-i~4
Modem transfer-based MT systems are based on
the following design principles : (i) modularity,
e.g. separation of linguistic data and algorithms,
(ii) multilinguality ...

1. Variable loading in mechanical joints:
Machine parts are often ... inertia forces in machines and mechanisms, forces
due to unbalance of the rotating components etc. Since these forces are to be
withstood by the joints, care should be taken while designing a joint ... variable magnitude. Design of two important
