Many speech enhancement algorithms that deal with noise reduction are based on a binary masking decision (termed as the hard decision), which may cause some regions of the synthesized speech to be discarded. In view of the problem, a soft decision is often used as an optimal technique for speech restoration. In this paper, considering a new fashion of speech and noise models, we present two model-based...
Predicting the High Intensity Radiated Field (HIRF) coupling in complex system is highly required in the aeronautic industry, which can be performed by electromagnetic simulation. But the validation of electromagnetic simulation is a difficult issue which needs proper flowchart and validation methods. In this paper, the numerical simulation by the parallel Finite-Difference Time-Domain (FDTD) method...
In many information management applications, sensitive information must be stored as a record and be retrieved when necessary. When the record is stored in a distributed way in multiple databases and shared by multiple users with different trust levels and accessing privileges, the trust management model is called M-to-M model. In this model, on one hand the record is stored in a distributed way;...
