Compression of speech from the TIMIT corpus was investigated for several transform domain methods coding near-best and best bases from cosine and wavelet packet transforms. Satisficing (suboptimizing) search algorithms for selecting near-best bases were compared with optimizing algorithms for best bases in these adaptive tree-structured transforms. Experiments were performed on several hundred ...

abstract We present a uniied framework for most of the known and a few new evaluation algorithms for multivariate polynomials expressed in a wide variety of bases including the B ezier, multinomial (or Taylor), Lagrange and Newton bases. This uniication is achieved by considering evaluation algorithms for multivariate polynomials expressed in terms of L-bases, a class of bases that include the ...

We construct two new families of basis for finite field extensions. Bases in the first family, the so-called elliptic bases, are not quite normal bases, but they allow very fast Frobenius exponentiation while preserving sparse multiplication formulas. Bases in the second family, the so-called normal elliptic bases are normal bases and allow fast (quasi-linear) arithmetic. We prove that all exte...

Studies were conducted on the anthelmintic property of about 15(e-h, 1e-1h, 2d-2f and 3e-3h) synthesized aminobenzylated Mannich bases bearing N-methyl piperazine using Indian earthworms Pheritima Posthuma against piperazine citrate as standard reference. Three concentrations of each compound (0.1, 0.2, 0.3% w/v) were studied, which involved the determination of paralysis and death time of the ...

external effects or opposabilité is a legal subject that some legal authors of france take advantage of which for clarifying the scope of the doctrine of the privity of contract and as a complementary principal. the use of the foresaid term does not go back to a long way and there is still a dispute over its bases. because the doctrine of the privity of contract is adapted from the civil code o...

The Balian–Low Theorem is a strong form of the uncertainty principle for Gabor systems which form orthonormal or Riesz bases for L(R). In this paper we investigate the Balian–Low Theorem in the setting of Schauder bases. We prove that new weak versions of the Balian–Low Theorem hold for Gabor Schauder bases, but we constructively demonstrate that several variants of the BLT can fail for Gabor S...

There is a close relation between comprehensive Gröbner bases and non-parametric Gröbner bases over commutative von Neumann regular rings. By this relation, Gröbner bases over a commutative von Neumann regular ring can be viewed as an alternative to comprehensive Gröbner bases. (Therefore, this Gröbner basis is called an “alternative comprehensive Gröbner basis (ACGB)”.) In the first part of th...

While RNA primary structure describes solely the string of bases, RNA secondary structure includes local intra-molecular interactions between pairs of bases, which form weak hydrogen bonds. Two such bonded bases are called paired. Thus RNA secondary structure can be represented as a sequence of bases annotated with lines between paired bases. A more intuitive representation displays RNA seconda...
