With the rapid development of electricity production, SO2 from coal-fired power stations causes severe air pollution problem. In 1997, the SO2 emitted from thermal power plants reached 7.,0 Mt, accounting for about 33% of the national emissions. At present and in the future, th...

This paper discusses the algorithms for achieving global states and self-stabilization for communication protocols. It first describes a primary algorithm including its suitability for achieving global states and limitation of self-stabilization for communication protocols. and then presents an impr...

A concept of secret sharing scheme with the function of assignment is proposed. It provides great capabilities for many practical applications. In this scheme, the dealer can randomly assign one or more than one participant to get the secret at any time, but these participants can get nothing about ...

A novel multi-view 3D face registration method based on principal axis analysis and labeled regions orientation called local orientation registration is proposed. The pre-registration is achieved by transforming the multi-pose models to the standard frontal model's reference frame using the principa...

Ontology evolution is the timely adaptation of ontologies to changing requirements, which is becoming more and more important as ontologies become widely used in different fields. This paper shows how to address the problem of evolving ontologies with less manual case-based reasoning using an automa...
