Let F be a uniform function of two complex variables to an additive introduced by Z. W. Sun in the 1980s. Suppose that x + 1, y ∈ Dom(F) for all x, y ∈ Dom(F). In this paper we establish the following reciprocity law: m−1 r=0 F x + nr m , my = n−1 r=0 F x + mr n , ny for any x, y ∈ Dom(F) and m, n = 1, 2, 3, · · ·. Several applications are also given.
The sparsity of the speech signals is utilized in the DCT domain. According to the characteristics of the voice which may be separated into voiceless and voiced one, an adaptive measurement speech recovery method is proposed in this paper based on compressed sensing. First, the observed points are distributed based on the voicing energy ratio which the… (More)
Task-and-role-based access-control model for computational grid [J]. Abstract: Access control in a grid environment is a challenging issue because the heterogeneous nature and independent administration of geographically dispersed resources in grid require access control to use fine-grained policies. We established a task-and-role-based access-control model… (More)
