Some theoretical aspects of generalised quadrature methods

Some theoretical aspects of watermarking detection

This paper considers watermarking detection, also known as zero-bit watermarking. A watermark, carrying no hidden message, is inserted in content. The watermark detector checks for the presence of this particular weak signal in content. The paper aims at looking to this problem from a classical detection theory point of view, but with side information enabled at the embedding side. This means t...

Some aspects of self-duality and generalised BPS theories

If a scalar field theory in (1+1) dimensions possesses soliton solutions obeying first order BPS equations, then, in general, it is possible to find an infinite number of related field theories with BPS solitons which obey closely related BPS equations. We point out that this fact may be understood as a simple consequence of an appropriately generalised notion of self-duality. We show that this...

Some Theoretical Aspects of the Critical Values of Birandom Variable

There are two types of critical values for birandom variable: the optimistic and pessimistic values. In this paper, some theoretical aspects of optimistic and pessimistic values of birandom variable are investigated. Based on the results, some properties of birandom chance-constrained programming models can be further discussed.

Some Theoretical Aspects of Language Learning and Language Teaching

1.1 Diffeerences and similarities between (a) the child's acquisition of his f i r s t language, (b) the child's acquisition of a second language, and (c) the adult's acquisition of a second language. The infant-child acquires his first language in the most natural o r least artificial manner possible. There is normally nothing in his mind to prevent him from ultimately learning a native langua...
