(metallurgy)
A procedure by which a continuous multiple-pass joint is completed by alternating the deposition of intermittent cross-sectional buildup and intervening lengths of weld metal.

When it is convenient, we also denote a layered permutation by the sequence of lengths of its blocks using a "hat" to denote when the corresponding block is an antilayer, and we call this sequence, the block sequence or the block decomposition of the permutation, e.
We formalize the definition of the block sequence of a layered permutation [sigma] as the unique sequence [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] of elements of [?
i] = 1 corresponds to the "hat" in the notation of block sequence defined previously.
Surprisingly, this relationship is not repeated between alternating and block presentations if the block sequence is reversed, i.
It can be seen that in this case, the effectiveness of news cognition is further lowered if the subjects are presented the news in an undesirable-desirable block sequence.
In subsequent tests, they saw alternating presentations of the previous block sequence and a sequence going in the opposite direction.
The T submatrix of each block is updated using Rule 1 noting that the starting time of the block is now known (from all the trucks which must precede this block in the optimum block sequence produced by the decomposition rule).
Since [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] is a block sequence, we have [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] mod [2.
Embodiments of the invention provide a class of mesophase separated ethylene/[alpha]-olefin block interpolymers with controlled block sequences.
The length of the block sequences increases until recall is no longer correct.
In the light of the postulated symmetry between the verbal and visuospatial working-memory subsystems (for a review, see Logie, 1995), a concurrent executive suppression task which does not put a significant load on either of the slave systems may thus be expected to interfere with Corsi span performance on longer block sequences or at the supra-span level.
Key statement: Embodiments of the invention provide a class of mesophase separated propylene/[alpha]-olefin block interpolymers with controlled block sequences.
