By means of an artificial neural network (ANN) model, higher measurement accuracy of integer harmonics can be obtained. Combining the windowed fast Fourier tran
This paper studies the digit watermark technology of numeric attributes in relational database for databases information security. It proposes a new mechanism b
We first discusses some threats to VoIP system and H.323 architectures designed for VoIP communications on security point of view. Continues with presenting sec
Several models of measuring case similarity in CBR systems are deeply explored. We also discuss the case matching process,and present three matching functions.
We combine the web usage mining and fuzzy clustering and give the concept of web fuzzy clustering, and then put forward the web fuzzy clustering processing mode
We cleveloped a high-speed information retrieval system. The system hased on the IXP 2800 is one of the dedicute device. The velocily of the information retriev
We address the problem of optimizing a distributed monitoring system and the goal of the optimization is to reduce the cost of deployment of the monitoring infr
A fingerprint matching method based on local relative orientation field is proposed. It extracts local relative orientation field around each minutia for minuti
