查询词典 a priori bound

The influence of the electric field on the properties of the bound magnetopolaron in an infinite-depth GaAs semiconductor quantum well is investigated using the linear-combination operator and the unitary transformation method. The relationships between the polaron's ground state energy and the Coulomb bound potential, electric field, magnetic field, and well-width are derived and discussed.

In this paper we have studied the Upper bound for the time derivative of information entropy for a dynamical system driven by colored cross-correlated colored noises. The Fokker-Planck equation was obtained by using the unified colored noise approximation. The upper bound for the rate of entropy change can be calculated explicitly based on the definition of Shannon's information entropy and the Schwartz inequality principle.

Moreover, an improved upper bound on the average MAP decoding error probability of linear Slepian-Wolf systems for stationary memoryless sources is derived. Based on this improved bound, we analyze the performance of Slepian-Wolf systems based on LDPC codes and random permutations, and prove that under some conditions, all but diminishingly small proportion of LDPC encoders and permutations are good enough for the design of practical Slepian-Wolf systems when the coding length is very large.
